This did happen to me on Intrepid, thinkpad X41 tablet. The issue was that the fingerprint reader would "crash", thus not being recognized by the USB subsystem anymore (error -71). The solution was to activate autosuspend for it: echo "auto" > /sys/devices/pci0000:00/0000:00:1d.2/usb4/4-2/power/level Then the device would virtually "disconnect" from the USB bus and reconnect upon usage, which does not only reduce energy consumption, but in this case helped that it would be recognized again.
