So apparently you are running some Ubuntu-based distribution and
"The UPS works correctly with kernel 7.0.2-6-pve, but fails with kernels
7.0.14-5-pve and 7.0.14-6-pve". 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
