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 suspect you can't actually get Gen 3 performance in this configuration. IIUC you should still be limited by the uplink to the host.
One "explanation" could be that the distance from the SoC to the Type-C connector is relatively long which would require a retimer to get the Gen3 speeds.
