![[RANT] The DUMBEST Thing About USB](http://i.ytimg.com/vi/gShRBsahzXg/mqdefault.jpg)
I realize it’s a generational thing, but compared to the disaster of connectors we used before USB, this is still a HUGE improvement. Never needing a gender-bender, null-modem, or centronix-to-db25 is what made it universal and all this modern BS is a walk in the park in comparison.
Back when I used to edit videos professionally, after each project was completed, I used to render out the final iteration of the video as "final.mp4"
But then I'd spot a mistake and call this one "final2.mp4"
But then the client will ask for a few tweaks; "final2_final"
By the time I'm actually done the file would call itself "final7_finalClient_v6_YesThisIsActuallyFuckingDone.mp4"
I'm guessing USB is going through the same phase
See this is why we have FOLDERS guys. File names are wrecked by other people but an organised folder system will easily deal with it!
Name it "Decent filenames are for pussies folder" and drop your client files in there lol.
@@DailyCorvid tags are even better
I can relate to this quite a lot. I've never edited videos professionally before, but I have done numerous videos as personal projects and I've done that exact same thing with the "final4_etc" madness.
Some of us don't have unlimited storage space, so we would overwrite "final.mp4" instead of keeping all the superseded versions. But PPro project files (or sequences within those projects) are another matter!
@@L4JP use a Version Control System with incremental backups, not full size backups.
I'm so exited for USB 4.1.2 Gen6 rev3-3 Mk2_final_final. It finally clears up the confusion between 4.1.1 Gen5 rev3-2 α6 and it's predecessors. The handy comparison chart is wonderful, and doubles as wallpaper; 6.5 posters completely covers your average room! Though seriously I think switching to a unified color scheme might be the best solution for consumers, most people could ignore the technobabble entirely: I plug into the yellow one for power, because yellow is electricity color.
Also I thought that the red ports were for bios recovery or something similar?
that name looks likes its from gmod lol
You probably mean USB 4.1.2 Gen6 rev3-3 Mk2_final_final hyper ultra mega supra speed, since USB 4.1.2 Gen6 rev3-3 Mk2_final_final is just a rebrand of past iterations.
If they made a standardized colour for each USB gen then all the Chinese companies will make USB 1.0 cables with that colour to rip ya off so India and China mess everything up anyway
I exhaled through my nose fairly hard reading this :)

This would never have happened under Clippy. Clippy would pop up and go "I see you are plugging a USB 3.1415265 device into a USB 3.131527 port using a USB 3.10 cable - would you like to reevaluate your life?"
I had a teacher we used to call Clippy. Then one day he tripped over and lost a tooth.
Poor bugger become chippy for the rest of his life :D Children are mean.
Yes and people would immediately click the Go Away button without considering Clippy's advice or has human nature changed in the last 20 years?
@@wayland7150 Nope, Clippy is gone, but human nature has not changed one bit.
I live in Japan and had the Japanese version of Office during the Office Assistant era - its Office Assistant character was a dog that was much cuter and less annoying than Clippy. But I still clicked Go Away without reading its advice (which was in Japanese, of course).
@@L4JP Well, you could always swap out Clippy for a cute little robot helper or a dog.
@@earthtaurus5515 The dog in English Office is different from the one I was thinking of. But now I'm discovering that my memory is fuzzy - the dog was related to Windows XP, not Office. His name was apparently Rover: ruclips.net/video/rjy53IOsC4U/видео.html
In Japanese Office, I'm now reminded that the default was a dolphin, apparently named Kairu. Did the English version have the dolphin as an option?
Here is a video of just Kairu's movements: ruclips.net/video/Plax9B2e9wM/видео.html (The video is longer than it needs to be, but it gets a little more interesting in the latter half or so, including animations I don't even remember seeing before.)
And here is Kairu in context: ruclips.net/video/WjZcgMFwTOU/видео.html (At 1min 14sec, the user typed the question we have all asked at some point: "How do I get rid of you?")
In a previous version of Office, the Japanese default was a lady named Saeko-sensei, which seems highly likely to be Japan only, as it fits the culture here perfectly.
Well, pretty sure the "Universal" is because it was supposed to replace the game controller port, printer port, serial port, ps/2 for keyboard and mouse we had before and it did.
Still, fuck usb marketing guys lol
No shit.
Yeah, it's definitely better than it was before. Otherwise we'd still be seeing manufacturer-specific charging ports for phones too.
Riley forgot the "SB". Literally "Serial Bus". In other words, he can still manage to be a smarty pants about 1/3 of a full concept, which is impressive.
But 33% is still an F.
@@porkstamina Well as manufacturers thinking about going 'portless'(port that needs a hole in this case), it will come back soon, dont worry, whit all the diffrenet magnet-based ports, like magsafe. (My only hope is a magnetic USB release that could solve this issue before it comes up)
I think it's important to note at 2:55 there are USB 2.0 Type-C cables so the connection speed could range from 480Mb-40Gbps
Yep. The majority of USB-C cables that are sold as "charging cables" are only USB 2.0. It has fewer wires and so is less expensive to manufacture.
@@userjames2009 I bought my mom Ulefone Armor X8, and I can confirm it uses USB-C 2.0.
this is my main gripe with usb-c, it supports everything, but unlike usb-a, you can't just LOOK at it to see what it supports, you have to blindly hope it works, and if it's e.g. usb2.0, you better label it, or you'll have to rediscover it's slow-ass all over again...
usb-A you can clearly see whether it's 2.0 or 3.x by the amount of pins, "more than 4 pins = good speed", and tbh, around usb 3.0 or 3.1 is enough for normal usage, and higher bandwidth is needed only for fancy stuff like stuffing video signal or gigabit ethernet over it (even usb2.0 should be able to do 100mbps internet I think, there are usb2 ethernet adapters)
@@userjames2009 Not only that, but these charging cables also tend to be easier to bend. Where as nearly all USB-C 3.x cables are difficult to bend
Bendy cables are way easier to work with, especially for just charging.
@@MrDeaf Exactly, and Thunderbolt (and presumably USB-4) is even thicker. The only exceptions are active cables like Oculus Link that convert the signal to and from fiber optic, so the cable only has the thin fiber optic line and 2 copper wires for charging. I wouldn't be surprised if active cables became more popular in the future for long, high speed, low wattage cables.
The very fact that they took existing specs and rebranded them is just insane. For example, taking USB 3.0 and rebranding it as USB 3.1 Gen 1 and then rebranding that same spec again as USB 3.2 Gen 1. Sure, they claim they are trying to make things more transparent for the consumer with USB4 since it has to be type C and 20gbps or 40gbps but just you wait until they make USB 4 Gen 1x2 or some BS rebranding for an older spec.
The only reason they did it was for marketing.
This way you can sell USB 3.0 devices as 3.2 and people with no technical knowledge will believe its better, even thought its exactly the same thing.
The same happened to HDMI for exactly same reason.
@@hubertnnn The thing is manufacturers dont all use the same terminology. When trying to find a motherboard some say they have usb 3.0, and others 3.2 -gen 2- gen 1. The thing is, they both support 5GB, because they are the exact same thing. Some boards even had usb 3.2 gen 2 while others had just 3.2.
I need that USB4 version 6 gen 3 revision 9 in light Antique Brass
@@warriorsmustang1784 yeah they dont use the same terminologie but you are wrong in youre statement usb 3.2 gen 2 is 10gbps vs usb 3.0 5gbps but its the same as 3.2 gen1.. but the fact is that this is complete bullshit....
That is some absolute bullshit.
I used to build computers with my dad when I was a boy, back in the mid eighties and I very much remember how ecstatic he was about USB when it came. A while ago, I told him about the current affairs with USB and he simply didn't believe me. «Nobody's that stupid», he said.
TBH, that's more or less me. I was psyched to get a computer that had USB in it, even though it was one of those early ports, I can't recall if it was 1.0 or 1.1. But, the ability to swap devices and choose how to divvy them up was amazing.
Not since the demise of Firewire have I been so saddened by choices with respect to connectivity. Firewire was awesome because you could access the RAM of a hung computer and dump that for debugging, something that is incredibly hard without.
@@SmallSpoonBrigade: Yes, it's incredibly crazy. Firewire, was of course, crazy for the reason you describe. Plug-to-hack is a bad idea. :)
@@jeschinstad Yes, but even with other protocols, you shouldn't be plugging in random things, do I'm not sure it's that much worse.
But, the speed was incredible.
@@SmallSpoonBrigade: Peripherals having direct access to main memory means they can be very fast, but it also means you have absolutely no security. While you shouldn't plug in random USB devices because they can be used to exploit vulnerabilities in the OS, it's still very different from allowing peripherals to bypass OS security entirely. One is a risk, while the other is guaranteed failure.
Please show your dad the new Intel naming schemes
I have been using USB forever. I have never learned about any standards. I didn’t know about colour codes. My strategy has been simple: if it plugs in, basically works, and nothing complains, that’s enough. After all, I remember hand-wiring serial ports.
It was only recently that I had to be aware of 3.0 or better USBs. Features such as Oculus Quest PC Link needs the faster speeds.
This is the way
That's until you need a USB-C to HDMI adapter. Those are hella picky.
That is the point of it. Once the connector fits into the rectangle shaped thingy, it works.
@@qT_p13 but it doesnt fit in the goddamn port and i'm jiggling it and it just wont *Turns upside down* oh never mind i had it the wrong way even though i tried that way first...
"There are still USB C ports that only support old 5Gbps"
Well, there are also ones, that only support USB2.0 or even lower.
Yeah, but you usually only find those on most products, such as the latest cutting edge phones and tablets like the Galaxy Sfuckyou HyperDeluxe and Galaxy TabTastic Number Edition. Niche products like random external ssd docks sold under a brand with zero recognition whatsoever use USB 3xyz ?Gbps, and I've even seen a few ssd enclosures with support for TB3 (and usb 3xyz ?Gbps).
A lot of audiophile products have USB C ports that are only 1.0 speeds
I just love that whenever given a chance, Riley will go on huge a rant about this new USB semantic.

And consider that wireless USB was a thing a few years ago...
yes the biggest rickroll by phone manufacturers, even the most expensive bbk phones use type C but it's 2.0 ffs
I have a keyboard with detachable usb 2.0 type c. The passthrough is 3.0 though.
ruclips.net/video/qkNev2lA-u4/видео.html finally it's here.
@@MayankJairaj well, the point of usb-c is to have universal cable... the phones have ALWAYS been usb2.0, so it's no surprise that most of them stay at 2.0, and only the higher end ones that support stuff like external displays, have any need for anything faster... the point for phones, is that usb-c is physically stronger, and that you don't need separate charging cable types, even if your device doesn't support some specific fast-charging, it would still be able to charge slowly, with ANY power brick and ANY cable... etc...
It's way faster to transfer files between smartphones and computers using FTP instead of cable. Yeah, the world has changed.
We need a revolution to overthrow the committee that names USB standards
The universal universal standard standards committee perhaps? The UUSSC for USB :D
Let's call it just NSB: New Serial Bus. Because then they can't call the second one new new sb.
I'd like to think that the USB Implementers Forum actually do want to simplify all of this, but every time they try to have an in person meeting to hammer it all out they can't ever get all of the necessary meeting hardware properly working due to USB cable confusion. I can dream, can't I?

Hell yeah Riley Reid is the best
@@swsephy 🌚
I swear he singlehandedly gives me life
My problem is I shouldn't have to read a spec sheet or reviews to determine if my usb-c cable is a true to spec cable. Keep it consistent with the speed, quailty, and colors and we're good to go.
But then someone would complain about not being able to buy $1 usb cables
Yes, and if you fail to read it, or understand it, the cable shouldn't be capable of destroying your devices.
Still, it's super-great that so many modern gadgets use USB to power themselves, instead of the myriad of proprietary power supplies in years before.
I even predicted this circa 2008, when I still had my OG Moto Razr -but not to this extent.-
Yep. Still remember a time where every phone had a different iteration of a charging port. Samsung used something different, so did the moto and lg. Nokia even had a few different ports and sizes for charging.
It would be nice if they could make it so the USB could power everything including printers and everything else that still need external power.
@@KevinBenecke Impossible. The more power a device needs the thicker the wires have to be. So unless you want a chunky USB cable as a standard, high power devices will need their own power sources.
@@hubertnnn Not everything could, but things like printers could easily work if laptops can
@@hubertnnn Not impossible, USB-4 supports alot of watts and most appliances don't require that much watts. The only appliance the USB standard won't work on (perhaps later versions) is a large fan assisted oven. The only reason electronic appliances won't switch over to USB connectors is the fuses. It's easier to replace a blown fuse in a plug then it is to replace an fuse inside an electronic appliance.

You can run usb 2.0 through a USB type C connector, as the connector is just the connector, it doesn't do anything else other than provide an electrical connection between things.
I hate when manufacturers do that, worse offenders are some Chinese phone makers that have USB-C but with 2.0 speed and their proprietary fast charging that only works with a USB-C to A cable on their brick.
Doesn't that depend upon the chips involved? USB 2.0 was only backwards compatible to the 1.x versions because it had extra chips to handle the other protocols.
@@SmallSpoonBrigade USB 2.0 controllers can run on slower clock speeds to support 1.0/1.1 devices, this has been built into every USB 2.0 controller. Up until USB 3.0, USB used just two differential wires (D+ and D-) to transmit data, USB 3.0 (or USB 3.2 Gen 1 as I think it's called now...) introduced two extra pairs for more bandwidth.
The available USB type depends on many things, including the USB controller, the USB device, the cabling, ports, USB hubs in between etc.
For instance you can have a USB C cable that only connects VBUS, GND, D+ and D-, connect it to the latest USB port and it will only support up to USB 2.0 (or lower).
I liked the older connectors more, because it was easy to tell what it was for.
Yes and when PC97 was standardized, they even added color coding to help with that. It was kind of overkill as it was mostly the mouse and keyboard ports that looked the same, but still nice and helpful. You could tell even the most ignorant of end user to plug the cable into the port of the appropriate color and the only bad things that could happen would be if they damaged the pins trying to insert it upside down, or swap the keyboard for mouse as those parts were more or less the same. It's been quite a while, so I don't even remember if that mattered after the computer booted.
How the USB standard should be, in my opinion:
usb-c 20.15 --> usb type-c port that handles 20gb/sec with 15w power delivery.
There are only three real parts, and if this were engraved/printed on ports OR the heads of cables, it would make it easier.
We already have the standard little lighting bolt to mean "charging port". This isn't all that much more information.
Or call it "USB-C 20GB 15W." I'm 100% sure manufacturers would switch around 20.15 and 15.20 if done in that format.
So why don't we just use USB-D 100W instead? Because it hasn't been invented yet. Do you see the issue here?
15W @ 5V = 3 Amps. Which in the world of power is not a particularly small number. 1.5 Amps is a lot more realistic with small chargers. Double of 1.5 A and you're starting to talk about some real hardware to manage it.
To understand USB standards fully, you need to take a full-time 4-year USB course.

Tried to buy a USB 3.x Type-C cable for my phone.
It was a nightmare... x.x I ended up having to read most of the technical specification just to be sure that what I ordered was what I really wanted. It's become a nightmare.
You most likely wasted your time doing so, unless you have a very niche phone with USB 3 speeds and not 2 speeds. USB 2 is still the default option for modern phones, since OEMs know that 99+ percent of smartphone owners never do wired data transfers anymore.
@@awesomeferret It turns out it actually has a USB3 capable controller - but has problems when run at USB2. I thought the same at first too but since getting the proper cable, it works as expected and no longer has errors. Fastboot and ADB also behave as they should now whereas Fastboot would lose connection way, way too often with the older cable. Its quite a nieche though... but that didnt make finding the right cable any easier and I probably overpaid for it x.x
it is the bus that is universal, as the name "universal serial bus" implies; the connectors and link speeds may vary, but simple adapters providing electrical and physical compatibility essentially ensure that what you plug in will hot-plug, and work.
ruclips.net/video/qkNev2lA-u4/видео.html finally it's here.
Esperanto pretty cool doe
"hot-plug, and work"
No keyboard detected press F1 to continue
It's not even a bus (not the schoolbus type... the electrical type) but a point to point architecture...
It is (originally) serial though, but even that is not fully true anymore as since USB 3.0 they use multiple pairs (parallel) to speed things up, so 'not-very-universal serial and parallel point to point' would be the new name...
Also, the universal refers to the origins of USB, when it replaced gameport, serial, parallel and a few more obsolete ports I've forgotten about, it became 1 universal connector for all those things, universal doesn't refer to the 'bus'
Also, USB is not electrically compatible, starting from USB 3.0, it uses multiple pairs making it electrically incompatible with USB 2.0 and older, requiring weird and bulky combined connectors. Same for voltage, used to be 5VDC, but can now be up to 38VDC I think with some power delivery modes...
You forgot the full size USB 3.0 Type B connector. It's used mostly on 3.5" external drive cases. As for port colors, my Dell laptop has black in all of its ports, USB 2 and 3, and the combo eSATA/USB 2.0 port.
Yeah I recently bought a keyboard with a detachable cable and a few of the reviews warned that the included USB-C cable fried their keyboard. Definitely something to watch out for
ruclips.net/video/qkNev2lA-u4/видео.html finally it's here.
It's because the standard just dictates the connectors and cable, not what you do with it. The first Rapberry Pi 4s had issues due to the way they were designed that caused issues when they were plugged into the wrong power adapter.
As soon as you started talking about manufacturer's coloring their USB ports for aesthetic purposes only, RAZER IMMEDIATELY jumped to mind haha. I have several Razer peripherals and a Razer Blade 15, so I am all too familiar with the green colored USD port 😂
I feel like I’ve seen this video before
I work on Lenovo machines and I can tell you they don't even follow those port colors... Sometimes you'll see the blue ones but sometimes they make them all black anyway no matter the speed and it's really annoying because the only way to find out is to check the maintenance manual or dig through the device manager.
They needs to come up with USB magnetic standard so that we don't stuck with all the manufactures making their own magnetic ports & cables.
Called Qi wireless charging
You can always just magnetise an existing connector? It wouldn't impede performance at all.
Yeah, pogo, magsafe, Microsoft's Surface. It's annoying.
@@DailyCorvid I've bought some magnetic adapters. The problem is that they aren't all compatible and I'm lucky enough that the two versions I have don't use the same polarity, so there's no risk of accidentally plugging the wrong one in. It should still be fine as the pins on the computer and device are the same, so the wires inside should also, but I worry a bit about such things.
0:17 Mi parolas Esperanton tamen.
It's actually amazing to be able to charge most devices with the same cable and charger! Remember the early years of this century when it felt like every single device had a different proprietary connector?! But yes, shopping for a laptop last week was still too much work. So, the c-ports on the T580 are half-thunderbird, so I can't do x, but the X1 Extreme has full thunderbird while the E580's c-port is only USB 3.1 (and that's just one brand, ThinkPad). And, which c-ports can I use to charge the laptop? And how much power do I need? Oh probably 45W when on with low use but maybe less when it's asleep or off, but we can't give you an exact number. Just try it. Then, so, which dock is just a USB hub and which is thunderbolt? The ad says thunderbolt but the ports look like it's only a hub. This other one has two c-ports on the front, but oh, those are labelled "usb-c" instead of the more useful "USB 3.1" that the type A ports are labelled with. Do they behave any different? Many hubs/dock have HDMI but good luck trying to determine which laptops output HDMI on the c-port. And, to output to two displayport monitors... Also, why are thunderbolt docks so expensive?!
I thought things were odd when my fancy new USB-C phone started powering the Dell MiniPC I use at work instead of charging from it. Ok, so that didn't actually happen, the phone just failed to charge.
The other flow that I missed in the video is the wrong implementation, e.g. in the Raspberry Pi 4 (fixed in newer revisions) or the Nintendo Switch were they didn't add a transistor to signalizes charges to charge. With the effect that some won't work.
I had already concluded that the world of USB was entirely awful based on prrsonal experience, but this vid shows that I've only encountered the tip of a gargantuan iceberg of confusion/frustration. How could it have gotten so bad?
lack of standardization, letting a corporation/private organization oversee the spec instead of an organization that specialized in standards, like ANSI, ISO, IEC, ECMA, IEEE, etc. One might recognize IEEE as the organization overseeing such standards as IEEE 754 (Digital Floating Point Number Representation) and IEEE 1394 (Firewire)
Design by committee.
I could see a software that lets you know when you got a mismatch and then points to a compliant port if your computer has one. This would be based upon the hardware you currently have plugged in and could even recommend moving some connectors around to optimize the situation.
Windows does this to an extent by default in file explorer
The beauty of having a standard is that there is a lot of variety
But if that variety is unpredictable it can mitigate the point of the standard by rendering it unusable due to lack of understandability
ruclips.net/video/qkNev2lA-u4/видео.html finally it's here.
The beauty of having a standard is basic compatibility/interoperability and minimum specs.
And all these years my only concern was looking at the plug before I plug it in, to pull it out of its state of quantum flux.

You guys ever plug a USB 2.0 into a 3.0 port 'just in case' the USB 2.0 wants some extra capacity? LMAO
Woah woah woah calm down buddy... I like to live dangerously but I'm not a bloody psychopath
USB started out well, no more different specific ports for keyboard, mouse, joysticks, modems, printers, plotters, display, external storage. But it gotten really confusing after 3.0 came out.
Also, USB Type-B physically fits (but doesn't work, obviously) into Eithernet port, both of which are often present in printers.
This causes a lot of confusion in offices, especially the ones without a dedicated IT guy.
One of the things that pisses me off THE MOST about USB is the power delivery. Prime example: smartphones and tablets. When you plug these devices into your desktop or laptop, chances are they won't charge anywhere near as quickly compared to using a separate dedicated charger. And apparently there are NO hubs / docks etc out there that support power delivery for the DEVICES -- they support it for the host only.
You're confusing USB with your laptop's limited hub power.
It's not USB's fault here. Plug stuff to the back of your desktop if you need it to charge quickly.
@@YounesLayachi I’m not. Desktops may support some quick charge standards, typically only on a single port, but this is NOT USB-PD (power delivery). Power delivery is only supported for a *single* HOST, not end devices, even on more expensive hubs and docks that use PD charging bricks.
@@5urg3x now I'm not sure what you're talking about. None of your USB A ports support power delivery (PD) anyway... but some of then can deliver more power than others
@@YounesLayachi I’m talking about a laptop computer - or a desktop computer - or even a powered hub connected to a laptop or desktop computer being able to provide PD to a connected end device like a phone or a tablet; this is not possible. Some may be able to do certain quick charge standards, but quick charge is a pain in the ass, for the reasons stated in the video. Too many different standards. A powered hub may support PD, but only on ONE port - the host port, for a laptop, for example.
3:26 if you’ve ever had to deal with a dodgy hard drive port you’ll know how frustrating it is that these are still widely used.
I honestly love USB-C but I wish we could all just go back to DB-25 connectivity. Sooo much more simple.
ruclips.net/video/qkNev2lA-u4/видео.html finally it's here.
Interesting that DB-25 was used for a variety of incompatible signal types and protocols.
Is the DB-25 port on your computer RS-232 serial, SCSI or IEEE 1284 (parallel printer), and if 1284 then is it standard, bidirectional, EPP or ECP?
Or on pro AV gear it could be eight balanced analog channels, multitrack AES3 digital audio (in one of a few different pinouts), or perhaps SMPTE 274M digital video.
And that's not to mention proprietary uses such as an Amiga joystick port.
@@abdicantrecursion8964 lol
Didn’t IEEE 488 use DB-25 connectors as well?
"but there is hope on the horizon!"
"oh yeah?"
"USB 4.0!"
"oh no"
Well, B in USB stands for Bus, I.e. it is about communication and protocol logic. Physical implementation of connectors has nothing to do with anything. Have you ever heard about internal connectors? Or maybe devices with built-in USB hubs? Keyboards with extra USB ports usually contain 2 independent USB devices: keyboard and hub, which connected using 4 conductors on PCB, you even can resolder your own device instead of hub. (See Ben's Eater video here in RUclips)
Ww shouldn't even need hubs! It's supposed to be an actual bus, so we should be able to plug them in parallel.
ruclips.net/video/qkNev2lA-u4/видео.html finally it's here.
@@JulianSildenLanglo yes,yes, but actually connecting it as hub device has own benefits.
Don't forget USB cables/ports that are for charging only and are actually missing the data pins.
As muddled as USB has become, I'm glad to be long past the days of RS-232, parallel ports with giant connectors, PS2 for mice and keyboards, and for phones... well... those springy handset cables that always twisted on themselves after you stretched them out because you tried to stand in a different part of the room while talking. How many of you are old enough to relate to this?
I mean, RS-232 is still widely used to this day (and the next few decades...)
this is a prime example of when you let only a bunch of techie guys design stuff for regular consumers.
More like marketing and sales. Basically what happens now is that the can sell devices with USB 3.0 and call them USB 3.2.
That way they can fool customers who don't know better into thinking they are getting the latest USB standard.
@4:36 your inner Gilbert came out for a sec lol
I didn't even know there were colors for USB, and I've been a tech nerd for most of my life. It always felt random. Every port on most modern devices I've owned are either white or blue for 3.0 or better.
Are you color blind wtf
I got to know about colors because my monitor's USB hub had a red one so I Googled what it means. And I am pretty sure the red color in this case means always on, it's definitely 2.0.
And my USB 3.whatever cable are purple lol
Thanks for the color scheme specs. For years I never bothered to learn what the colors meant (not that it matters anymore apparently). My Gigabyte monitor came with a crazy USB 3.0 AB and I just don't know why they keep making variants with the same specs.
USB: We always hated that word "universal." We've been trying hard to get rid of such notions.
That's a bit sensational.
Because in truth there is definitely a universal interface due to backward compatibility. Speed may not always be optimal, but I can connect modern devices to 20-year-old cables and vice versa.
Them young'uns don't know their born. In my day we had 25 way RS232 to 9 way RS232 and Centronics cables and PS/2 and loads more.
It is indeed. USB has been incredibly successful in consolidating almost everything into a few types of ports and being able to charge your devices with basically anything. Complaining that a port might work at 5Gbps rather than 40Gbps or it's the wrong color...
From the title, I was expecting something like every device and operating system having to implement a ton of custom code/integration to be able to work. To an extent this is essential complexity and e.g. printer drivers are a necessary evil to manage that problem.
Also be sure to note that there are USB C 2.0 cables. You can actually find those on Amazon, and I was nearly scammed from one seller who kept sending me those when I ordered 3.0 cables. It was clearly on the label what they sent me, so they were either hoping I was blind, or they were the blind ones.
Do people actually not know this? Wow.
It's the same reason why 3G was never actually 3G, going on to 4G, 4G LTE, and now the various flavors of 5G. The sales team steps in and mandates putting certain names on the product, and nobody's able to stop them because the standard isn't actually enforced in any meaningful way.
Yeah, the marketing department bullies all the engineers and gives them wedgies until they agree to change the numbers.
Don't knock Esperanto, that was a beautiful dream. Everyone learns two languages and the second one is cake to learn for half the world and still pretty easy for the other half. Bam. The whole world can talk to each other. Breaks my heart it never caught on.
USB c can also do usb 2.0 speeds which you did not mention (my phone for example)
i thought that was more dependent on the internal storage, my note 9 storage was barely faster than usb 2.0 iirc
3:12 That's why I only use cables and chargers for my tablet and phone that are the same brand as the devices.
As a fluent Esperanto speaker who's very familiar with the shortcomings of the language, I was both pleasantly surprised and appreciative of that joke at the beginning
Ignoring the specs, I think it is pretty much universal. All devices have them, and when you plug it into the thing it just works. Dont even have to setup an IRQ for my LPT port.
Most annoying thing I've ever had the displeasure of setting up was a Gravis Ultrasound Max. First you have to set all of the jumpers for IRQ, DMA and IO ranges, then once the configuration software can find the card, you have to setup a few more that don't have jumpers for things like SB compatibility. And once you think you are done, you find out that something else quit working due to IRQ/DMA conflict. Many a days were wasted trying to figure out the perfect setup where everything works at the same time.
Tell that to USB-C only portable monitors that are WORTHLESS to me even tho my Laptop has 2 c ports. ZERO support for video over usb-c on the laptop so I am pretty much forced to use a portable monitor with an hdmi port and separate USB port for power
@@Montisaquadeis i feel like that is a cable or a configuration problem, not actually a port problem to be fair.
@@qT_p13 nope NOT all ports atr treated equal
@@Montisaquadeis well It is a fact that the whole usb standard has gone off the rails since it first began. They definitely lost the plot.
why does "usb micro b super speed" rhyme awfully good
Calling something "universal" and having this many iterations in the first place is already a crime against logic.
They all still work with each other though. Making it FAR more universal then the wide range of different cables it replaced.
Isn't that the very definition of universal though? Different iterations still fit in the same slot.
The much stronger counter argument is that it's very very appropriate to call it "universal" because... It truly is in a way that nothing else is. Sorry but it's very very hard to defend your position. The speeds are not universal, but come on. The fact that you can plug a 20 year old flash drive into a modern computer and be effectively entitled for it to work without any adapters is the "universal" in USB. The only standard that's more universal is the 3.5 mm headphone jack. Frankly it's a bit shocking that 9 people upvoted your comment, considering how illogical your statement actually is.
I'm seeing more USB A ports that are black regardless of the speed. Sometimes the symbol next to it will tell more information about the speed and power delivery. Just my 2 cents.
I'm glad someone is finally calling usb-c what it is, a connector! So many people on RUclips talk about usb-c like it's a standard in and of itself and it isn't. This can be very misleading for people and I really wish a lot more places were a lot more clear about this.
At least we can be certain that a usb cable from Apple will be overpriced
and never be on sale. 8o)
Reminds me of the shitty old days when printers were connected with big ass parallel cables. Joysticks were hooked up to the 15 pin D-sub "game port" which found its way onto the sound card. Back then differential serial signaling was something worth bragging about. Even the PCI bus had single-ended singnals which referenced to GND. Today, virtually all highspeed electrical signals come with serial timing, transmitted through differential pairs, even display panels come with crazy fast LVDS lanes. The keyword "serial" is no longer seen as a highlight, but rather a mark of history.
Biggest problem is that while they all look the same, except coloring, if they will do their 20 gbps or fast charging is decided by their controller on the mobo, and that might still be good old usb 2.0 controller.
That's life.
Fun-fact a port that accepts this cable, will also accept a standard Micro usb cable; you just dont get stuck with 2.0 speed. (so if you have a device like an external hard-drive that requires one of these, but you cant find a cable, you can make due with any micro usb)
usb is equivalent to "you had something nice but you went and messed it up"
USB began with a lie. It came out around the same time as "plug and play," and the #1 advertised feature was "no more driver disks!" That boast quickly disappeared when devices other than HMIs hit the scene.
3:25 we still use that funky thing for external drives
usb specs and names make me want to ventilate my skull with a hunk of lead
Yep, confusion still gets the consumers who doesn't know a thing about what USB they'll need.
I love the new usb A and usb c charges. All of the usb a ports are capped at 10w charging but to find that info is actually insane.
Many people think USB-C means it's USB 3.x, but not always. Many laptops with USB-C most likely support 3.x specs, but many phones still likely have 2.0 data specs.
My video lagged and I didn’t realize and thought Riley was just standing g there and totally thought it was normal
I can hear the Esperanto studiers screaming right now. That bite at them was a giant chunk 😂
USB 5 where at least everything from the past is mandatory & supports all the alt modes & Thunderbolt... Not sure about VirtualLink though.
They had room to go from 24-pin to 26-pin & just add in ID/Data & clock signal connectors.
You misunderstood the mean of universal in the term. I came from 90s when the mouse works on serial port, keyboard has its own port, printer too etc.
Why we just don't call USB by it bandwidth?? USB 5Gbps, USB A 10Gbps, USB C 10Gbps, USB C 480Mbps etc. It would be so easy and impossible to mistake! Even people that doesn't give a damn about tech would understand, the higher number, the better.
USB 3.0 exists since 2008? Damn... I still refer to it as "the new thing" 😭🤣
My favorite is the orange standard for high retention force.
1:50
*looks down at my neon green USB ports*
Feeling personally attacked right now.
Universal is referring to the fact that you could make just about any peripheral connect through a USB port instead of all the various ports that were used before
Universal serial *Cool Aid Man of Disruptions busts in* "Oh Yeah!"
Well, we had a nice thing...
I've read through the USB1.1 documents multiple times and I know there are tight specifications for cable length, shielding and even what color each internal wire must be. I don't recall anything about port colors tho. Pretty strange.
Not to mention the increasingly smaller pin sizes are great for dust and pocket lint. Gotta flip the cable around sometimes to get it charging
hmmm My phone has a USB C port, my PC has a USB C port...stick cable in, phone go charging. Perfect.
One thing that doesn't ever get mentioned is that the whole color coding debacle doesn't even apply to USB-C because of the physical design change, leaving you with nothing but the purposely confusing naming scheme that will ALWAYS be truncated to "3.2" for the sake of consumer confusion.
Imagine a world where every connection is USB-C, your keyboard, mouse, phone, monitor, microphone, everything. Even your GPU can just connect anywhere to your motherboard and stream via the USB-C ports on the motherboard so you don't need a traditional GPU anymore, you could have a cube GPU, one that fits to the top of your case, etc.
you don't need a traditional GPU anymore, you could have a cube GPU, one that fits to the top of your case, etc. Then people will be building cases that encompass your cube GPU, cube CPU, etc
Basically, such complexity is inevitable once the decision was made to put different signals, including power, into the same physical form factor. Now there will be always guesses at what a given physical port supports, since it makes no sense to support all functions in all instances. That is more an issue for me than speed of the USB part itself
The most annoying thing is USB cables will often not list their capabilities. Often they won't even list the basics, so I can be in a store looking for a cable and literally not know if it's even vaguely capable of what I'm looking for. Looking for cables and chargers for the Steam Deck will likely be a pain, as you need a minimum wattage to charge while playing, and I'd like it to be able to carry a video signal.
I beg of you to make a full video on USB bandwidth. It would make my life and I bet a lot of other people's lives a lot easier.
I have a few of those old power supplies with the globbed on extra pins
The same is true for usb-c cables too! I just do a file transfer to an SSD to check speed
Whoever came up with that super-speed micro usb design really, REALLY should be fired for that abomination.
I have no faith that USB4 will fix anything at all. The USB cable market is loaded with so much false advertising that you'll probably end up seeing cables that can only support 2.0 speeds labeled with it.
Not only are they not universal, the “Micro B Super Speed” doesn’t even look serial.
