USB 3.2 used to be what we now call USB 3.2 gen 2x2, doesn't it? So it used to be that the version dictated the max speed: 3.0 was 4Gb/s, 3.1 was 10, and 3.2 20, right?

But then they decided to memory hole that and now USB 3.0 and USB 3.1 are also USB 3.2 and USB 3.2 is called "generation 2x2", whatever that is supposed to mean

It makes no sense anymore. It used to be quite simple.

No, they just renamed things when new standards were released (3.1 and 3.2). 20Gbps wasn't possible before 3.2, and it called Gen 2x2 at the time of release.

5 and 10 Gbps were renamed, though.

5 Gbps first was USB 3.0, then 3.1 Gen 1, then 3.2 Gen 1.

10 Gbps first was 3.1 Gen 2, then 3.2 Gen 2x1.

3.2 Gen 1x2 is also 10 Gbps, but physically different

Do any real devices use 1x2? I think we largely escaped that mess and it's mostly a strict progression of 5Gbps, 10Gbps, 10Gbps*2, 20Gbps*2, 40Gbps*2
