Can you please see if you can repro and fix this?

This all was with current 5.16-rc3 on a tigerlake nuc.

Also, perhaps you can update the guide on what sort of setup/cables
etc.. you need when either the host or the client is a usb3.1 usb-c only
device.

+ Mathias, maybe he still has a USB 3.0 debugging cable.

Should have at the office, I'll pick it up next week and try it out.

Is someone at Intel responsible for this thing? get_maintainer.pl
doesn't think so:
