Every time a new USB spec comes out the version number goes up. A new spec comes out because they add more features. The spec is a whitepaper that explains all the features. It's a "The King is dead, long live the king!" situation.
If you just never used the version numbers to mean something that they never meant (transfer speeds) then literally none of this is confusing.
They've officially renamed the transfer speeds one time after people made a big huff. here's how they changed:
USB SuperSpeed -> USB 5Gbps
USB SuperSpeed 10Gbps -> USB 10Gbps
USB SuperSpeed 20Gpbs -> USB 20Gbps
And If you can't follow along with that, I'm really, really sorry. There's not much I can do from a internet discussion board. XD
the whole USB 3.2 Gen 2 2x2 (hands of blue) bullshit
If you're not trying to wire your own USB port you can just use the recommended names "USB SuperSpeed 20 Gbps" or "USB 20 Gbps". You don't have to be confused by technical names if you don't want to be.
The real bullshit is between your ears--you and only you can fix it.
A device or port that does 480mbps transfer speeds is a "Hi-Speed" device/port. That's the real name and always has been.
It doesn't matter what version of the USB spec it was certified under. If it was designed between 2000 and 2008 it was certified under USB 2.0 or 2.1
If that device was certified between 2008 and 2013 then it was certified under USB 3.0. That absolutely doesn't make it a "SuperSpeed" device/port, but that's more than clear when we use the real names.
They are a Silicon Valley-based foundation half-heartedly rehashing Silicon Valley's worst trends.
The truth is, you have to do these sorts of things to attract and retain talent, even if they aren't great ideas.
