USB connectors and specifications tutorial, including USB 1.1, USB 2.0, USB 3.2, USB4 Version 1.0, and USB4 Version 2.0. Video also covers USB DP (DisplayPort), USB PD (power delivery), as well as the USB Type-A, Type-B, Mini-B, Micro-B, USB-C and nine other connectors. :)
Information for this video was primarily sourced from specifications included in the Document Library made available by the USB Implementers Forum at: https://www.usb.org/
Inevitably, as always, I've had to decide what to leave out, as well as what to include. Given the number of USB specifications and revisions that exist -- for example, there have now been 17 just for power delivery -- the only sure way to check anything for certain is to look at the instruction manual or online specification for your particular device. This said, right now, if you need the highest specification, go for a device with USB4 ports, and purchase USB power cables that support 100W -- or 240W if you can get hold of them. :)

Its so interesting that we once thought host and component plugs had to be different. Like for no reason at all we couldnt have a universal reversible cable that could plug into both. Its just odd that thats how we started from. I woulda been so much simpler to just make usb-a to usb-a. A and B are so similar in size

I have a samsung 12 inch tablet that has a double usb outlet. You cannot plug in a thumb drive like the smaller tablet. I wonder when they will make a USB C thumb drive. 73

thanks to this video, I was able to prove a friend that a USB-B 2.0 fits in a USB-B 3.0 Port! 7:02

I've never been this enthralled by what is in essence a boring slide presentation about a topic I mostly know already.
If ever there was a Platonic ideal for an informative and well paced presentation it is this video. Great work and definitely very valuable for someone who hasn't grown up watching all this unfold while working in IT. Great work!

@michealdufresne5509 Says:
people who make USB
_USB 3.0 is USB 3.1 Gen 1 Which is USB 3.2 Gen 1x1
The Connector Doesn't Mean it can Support 5Gbps or 10Gbps
it'a a Man With Different Names & Faces,why're you so confused?? what's so confusing here!_
😂😂😂
@contactrpg5936 Says:
Why say 80 GBit per s is 600 GByte per minute? Much clearer to put it as 10 GByte/s
@LawpickingLocksmith Says:
USB means Upper Side Band. Theft has resulted in a mess.
@jamesf2697 Says:
Great video! If you make an updated video, please include clarification for people who don't understand the difference between a bit and a byte. This one got me for so long. Thinking a would be able to transfer a 10GB file in a second 😂
@brendanfalvy1281 Says:
Can we lease get a legal body to regulate good minimum standards for USB cable construction then.
@sfaustina Says:
Jeeez i needed a refresher, thx for the video. yrs of tech stuff and loads of cables. So confusing 😅 think im going to go back to a typewriter, landline and a disposable camera.
@yodek1846 Says:
09:08 - Seriously?! 🤯 I thought that was completely new versions of USB... turn out, that they changed names... bastards!
@avinotion Says:
I'm new here. Are rodents a staple of this channel?
@RUHappyATM Says:
I'm CONFUSED.
Edit: I suppose I will wait for USB 5.0 and just send all my obselete PCs to the landfills.
@guessundheit6494 Says:
Bring back serial and parallel!
@airborne2876 Says:
The USB 4 standard is insanely over powered. Insane data tranfer speeds, audio and high resolution video supported. Pretty much every connector possible in one.
@JohnDavidSullivan Says:
Coming back to this video just to vent my frustration. I'm sure I'm not the only one - Chris you alluded to it in the video. I was actually unaware there was a USB4v2 until recently, can't wait for USB 4v2 gen 2 😏. So I work as an AV technician in the IT department at a London university, I can't emphasise enough the frustration with the USB standard, when my boss and I had to setup meeting pods and getting USB devices to work with USB C and the power delivery with managed Lenovo laptops was an absolute nightmare, basically because the contractors had installed the wrong spec USB C that were incapable of providing enough power to be used with the laptops we had provisioned. We had to add our own setup using kit from amazon and tell staff not to use the ones that were in situ.

I had no idea mice were called rodents

I have a wireless rodent these days, but it does still use USB from time to time

Thanks. My port is red.
@cheekyoscar1353 Says:
thanks for your quick thumbs up just one question. What is the difference between HC & XC
AND Does it matter if I'm using an A1 card in a dash camera where the A1 is not needed . thanks
@ObiWanBillKenobi Says:
3:17 Rodents? Are there other USB animal-name peripherals that are not mice?
@Kirmo13 Says:
I bought a new HDD to use as cold backup storage and to my surprise it came with an usb micro-b SS connector. I've never seen one in the past and I was very surprised to see it in 2024
@austinharding9734 Says:
this video explained it PERFECTLY, now I understand EXACTYLY why I'm so confused

@placeholder3853 Says:
For something so universally used as well USB, the naming really is a mess. Renaming the standards was possibly the silliest thing they did, and the worst part is it wasn't even remotely necessary.

@joeniemand9047 Says:
could you perhaps give me a source for your power over usb facts?
I've been having some high power draw notifications on my phone from a connected nvme enclosure
and it would seem that my S23 Ultra USB3.2 type c power only gives 5v900ma ? :( not enough to power the 5.4W nvme drive.
@mihailvormittag6211 Says:

@tutacat Says:
Alt mode completely changes or adds a different signal to the connector, such as DisplayPort, or PCIe lanes
@tutacat Says:
USB 1.0 requires data for any power

Thank you for summarizing the USB.
@Rinzler0001 Says:
This is such a severely underrated video! I personally can't think you enough for this one. I've always scratched my head as to why the nomenclature went the way it did.
Sometimes I think it was done on purpose because a few people wanted to be a**holes. People have done worse for less. 🤷♂️
