The retroactive renaming of speed+versions. I'm not talking about the Mac.

My whole argument is that this confusion wouldn't be an issue if the USB Consortium had reserved USB 3.1 for 10 Gb/sec speeds exclusively. In other words, this:

    3.0: 5 Gb/s  "SuperSpeed"
    3.1: 10 Gb/s "SuperSpeed+"
    3.2: 20 Gb/s "SuperSpeed++"

That, and that alone (with none of the "Gen" nonsense) would avoid confusion. Then, if I pick up a USB 3.1 device, I would know it's 10 Gb/sec "SuperSpeed+" without having to use a stupid "generation" number. But no, the USB Consortium decided to deprecate 3.0 and 3.1 because all new devices are "3.2 Gen whatever". That's confusion.

Versions are not speeds.

3.2 continues to describe everything in 3.0, which means it continues to describe how to make devices supporting 5 gbps over USB-A/B

Well, the argument is that versions not being speeds anymore is the problem and it would've been easier if they were. Like they are in Wi-Fi for example.

If you use the smallest version number that fits your device, then you avoid confusion.
