“USB 4 2.0”… someone should really do something about the incredibly goofy naming scheme.

These are all equivalent, which is dumb as fuck:

• 3.0 / 3.1 Gen 1 / 3.2 Gen 1
• 3.1 Gen 2 / 3.2 Gen 2 / 3.2 Gen 2x1

I suspect the corporations that influence USB did this specifically to confuse consumers (increase sales) when they could have told them exactly what they were getting e.g:

• USB3 5Gb
• USB3 10Gb
• USB4 500Mb/100w
• USB4 20Gb/100w
• USB4 40Gb/20w
• USB4 80Gb/240w

The jump from 3 to 4 could’ve indicated the change to USB-C ports, which should be the greatest breaking change for USB (otherwise it’s no longer USB). The “/Xw” could’ve been used to indicate PD max watts.

This can also continue indefinitely, like “USB4 10Tb/500w”, “USB5 5Pb/2kw”, etc.

What I’d really like to see are regulations that require manufacturers to specify the actual speeds the specific component(s) model/batch have achieved under real world testing — both best case scenario and averages — as the theoretical limit is completely irrelevant; with wild variation between cables of the same specs.
