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. :)

Cables are now starting show the charge and data speeds on the plug.
i.e "18W 5 Gbps" for a standard USB-A former 3.0 cable, or "240W 40 Gbbs D" for a USB-4 cable with display support.
I have seen the same on brand new motherboards.

I have an hard drive that has a male to male USB - A cable
@artramirez3506 Says:
I can't wait until all the legacy ports are eliminated as well as the slow speeds. USB-C all the things!!!!😅
@artramirez3506 Says:
I hate how we have USB cables these days that support charging at like 50gigawatts of powah!!! and which are still limited to data speeds of only 480mbps. Lol. 😅. Yes I know they are intended for different cases but still. Lol
@terrance_huang Says:
and the first usb4 is usb4 gen2, and it has 20Gb/s x 1 lane
@nagarathnam2010 Says:
Thank you so much sir 🙏
@QuicksilverSG Says:
TL;DW: USB started out with two connector types: USB-A for computers and mice, and USB-B for printers.
Later they came out with mini-USB connectors and USB-3, which used high-speed blue USB-A connectors.
Everything they came out with after mini-USB and before USB-C was misguided, obsolete garbage.
After way too much bullshit, they came up with USB-C, which actually works as advertised, end of story.
@Aulia.Aliyev Says:
My key takeaway is this: humans want smaller USBs (to save space in their devices) with bigger bandwidths. Hence the not so universal Universal Serial Bus
@JamesMiller-v4s Says:
I am a type AB+. Is there an adapter for Type O?
@Mvvkt Says:
Did you know that the USB 3 version is called USB 3.2 Gen 1 today not 3.1 Gen 1? The table on the video is slightly wrong or outdated. Also the Wikipedia article on USB has a nifty SVG graphic explaning the retcons, lol, your video is handy however if one is no the reading type, which many aren't nowadays sadly! Aso on the USB hardware article on Wikipedia there's even a nifty colors table!
@JamieTheEnby Says:
There is one more absolutely cursed connector called Mini USB-B 3.0, I only have one device that uses it and it's a external IDE 2.5, IDE 3.5, and Sata tool I got, I thought I've seen everything.
@roybragg9999 Says:
Great explanation. Thanks.
@Banana85021 Says:
If it was not for your vid and the EU the iPhone would not have USB C 😅
@Mystic-Voyager Says:
great video
but "rodents"? lol
@bearweston8350 Says:
Why not start using other colors instead of blue for each new specification & speed.
@GTAManRCR Says:

a rather precise and brilliant delivery of very useful knowledge .
thank you professor .
@aibulat1871 Says:
Awesome explanation! Do u happen to have a similar video for Thuderbold, potentially including differences: Thunderbold vs USB. Like usb polling in cpu vs DMA used in Thuderbold?
@robertphilip1832 Says:
I can't understand who and how can accepted the idea to put several watts power delivery into this tiny little contacts. I saw my collegaue daugther macbook's connector, the contact pads disappeard. Same winth my ipad and iphone lightning connector, almost same size contacts. You cant use as much of them to be enough to handle these ampers.
@jpegxguy Says:
I have 2 questions/suggestions:
1) I love your "Explaining X" series. Do you have a playlist/Could you make one?
2) Do you have a video on "Explaing CAT cables and connectors"/Could you make one?
Love the no BS clear content
@jpegxguy Says:
Why did they rename evrything lmao that's horrible
@mummoorthy6511 Says:
Thanks for good explanation 👍

EC videos are the gold standard for computing-related topics. Thank you for making computing more accessible and relatable for everyone, Mr. Barnatt, and kind greetings from Mexico.

Funny to think that USB is "Universal Serial Bus":
The cable standard to END all cables!

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

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.
