Comment 15 for bug 1998103

hi, i am seeing the same problem. I think the reason is the automatic saving of energy.
In my case, if you use the powertop tool and carefully look at the Tunables tab, you can find Autosuspend for unknown USB device 1-1.3 (8087: 07dc)
change the state to bad and the problem no longer persists until the next system reboot.
