After a few days of normal operation, all USB devices stop working on my PVE 9.1.1 host. After reboot, lsusb outputs all devices but after a few days, lsusb outputs nothing and no USB devices (keyboard, mouse, UPS) work anymore. This scenario has been repeated multiple times.

I run the following commands at startup to save power:
echo "powersave" | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
echo balance_power | tee /sys/devices/system/cpu/cpu*/cpufreq/energy_performance_preference

and recently added usbcore.autosuspend=-1 option to the GRUB configuration. But this had no effect.

Any suggestions on what could be the problem would be greatly appreciated.
