I would rather suspect a problem with the hardware.
Disconnecting is normally an action of the attached device, not of the
driver. 

  https://docs.kernel.org/6.0/driver-api/usb/power-management.html#what-is-power-management
mentions "autosuspend" but i cannot find an example of a system log
message which would announce such an action.

This systemd rule is supposed to disable autosuspend.
This supports the suspicion that the disconnect is not caused by
the operating system.


Have a nice day :)
