Comment 8 for bug 1332722

I am having this problem as well, however, the only difference is that once the USB 3.0 device drops, no devices are recognized via any USB 3.0 port until a reboot. When this happens, USB 2.0 ports are unaffected.

Mint Cinnamon 17.2, up to date (according to Update Manager).

Motherboard: ASRock 970M Pro3
