Title:
Kernel turns off USB-devices
Status in linux package in Ubuntu:
Confirmed
Bug description:
Kernel turns off USB-devices.
A mouse connected to an usb-port works until some time. Then this device is
turned off and never turned on again. I tried to turn off power saving for such
devices, but without success.
This started with kernels 5.4.0-49-generic and later. I do not see
this with kernel 5.4.0-48-generic.
This bug renders all usb-ports used unusable. You can unplug the
device (a mouse or keyboard) to an unused usb-port. But this will be
switched off then soon too. At some point in future you are out of
working ports, because all of them are switched off and never on
again.
