Now this is odd... I've tested another cable - a very short one used with a Gen3 nvme enclosure that I'm sure it's working - and I got Gen2 20 Gbps. I also have tested this on Windows 11 and I still just got a Gen2 connection. I was almost sure it was caused by a bad USB4 implementation by the PC manufacturer, then I tried to connect a Thunderbolt 3 disk enclosure via daisy chain to the Caldigit dock and I got the full Gen3 40 Gbps connection! See the attached picture. I'll try to connect the dock to a laptop via Thunderbolt 3 as a last test and I'll report back.
