In the dmesg you shared above, there are still unplug and USB tunnel creation fails so you only get USB 2.x connection with all the USB devices on the dock. How do you determine if it "works"? I guess keyboard and mouse (both USB 2.x devices) and display (tunneled over USB4 link) all are working right? However, if you plug in USB 3.x device to the dock it enumerates as FullSpeed instead of SuperSpeed. There is definitely something wrong here. I asked from our TB validation folks if they have any experience with this dock but did not receive any reply yet. What you mean by 40Gbit mode? The dock exposes two lanes both at 20G so it should always be 40G since we bind the lanes, also in Windows. Also In Windows, do you see if the all USB devices on the dock are enumerated as FullSpeed or SuperSpeed? I suspect it's the former there too but can you check? Keyboard and mouse should be FullSpeed but there is some audio device that may be USB 3.x (SuperSpeed), or alternatively if you have USB 3.x memory stick (or any other device) you can plug that to the dock and see how it enumerates.
