This happened back in the 4.8 release candidate and I thought it would be fixed when the kernel went stable but I'm still having the issue. The kernel seems to randomly reset my USB controller or do something to that effect. Basically all my USB devices stop will randomly stop working and I have to force reboot the system to get them to come back only to have them work for 5 minutes or so before doing it again. I've rolled back to 4.7.6 so I can use my system but 4.8 just doesn't seem to want to work with USB. I've attached a segment from my syslog that I think shows the issue.
