Please, get real. Look at any computer or motherboard spec sheet. They're not listed as SuperSpeed because they can operate at a range of speeds.

That's for *hosts*, which in fact must support all speeds for any given USB spec version they claim to support. *Devices* were never supposed to put the USB version front and center. What people care about is the transfer rate they use.

This is what a device controller spec sheet looks like: https://www.nxp.com/products/product-information/ip-block-licensing/usb-2.0-full-high-speed-solution:USB-2-FULL-HIGH-SPEED-SOLUTIONS … Note "USB 2.0 Full-Speed". The version specifies the spec it's based on, the speed what transfer rate(s) it actually supports within that version.

First random consumer device on Amazon I found: https://www.amazon.com/ORICO-External-Enclosure-Installation-Supports/dp/B01MYTZW5R/ … Note "SuperSpeed USB 3.0". SuperSpeed comes before the USB version even.

So for example someone literally just tweeted this Into my timeline. https://www.amazon.com/dp/B06XC1WGQR/ref=cm_sw_r_cp_apa_i_5jPDCbFR8X606 … "USB 3.1", it proudly claims... and then you scroll down and see it's actually only 3.1 gen 1, and so will operate at max speed on 3.0 ports. No 3.1 necessary.

Yeah, so that marketing is garbage and is exactly what USB-IF does *not* want people to be doing. But I guess they won't listen. I mean at least USB-IF are *trying* to get people not to do that?

If USB-IF stopped rolling forward old versions it would happen much less. But their members want the confusion. They want to be able to slap the latest version number on old hardware. This isn't unique to USB, but it's the offender with the most reach.
