The ports are supposed to be labeled using friendly customer names like “SuperSpeed USB”. https://en.m.wikipedia.org/wiki/USB_3.0#USB_3.2 See “USB-IF recommended marketing name”

* 5 Gbps transfer rate: “SuperSpeed USB”

* 10 Gbps transfer rate: “SuperSpeed USB 10/Gbps” - applies to both Gen 2x1 and Gen 1x2.

* 20 Gbps transfer rate: “SuperSpeed USB 20 Gbit/s”



I think the quotation marks should go around the phrase "friendly customer names".

I have never been able to differentiate between "Full speed", "high speed" and "super speed" though I guess they are each different from "low speed. Of course there are several speeds all labeled "SuperSpeed+"


5Gbps, 10Gbps, and 20Gbps seem like pretty clear names to me.


And then you connect two devices labeled with "SuperSpeed USB 10 Gbps"... and it turns out that only 5 Gbps works, because one device was Gen2x1 and the other Gen1x2?
