Also with "Ubuntu mainline 7.1.5". If your distribution supplies such kernel packages, I would suggest starting with narrowing it down to a single exact release, e.g. "7.0.8-3-pve is the first broken one". This will make bisecting faster, or maybe there will be few enough USB and HID changes in this release that something will become obvious. Regards, Michal
