Got this great box from Emsti. Installed win 7 Pro on it. It runs great, but when I leave it for a while, the USB ports lock up and I need to reboot to get them to work. Checked the power settings and was surprised to actually find a setting to turn them off to save power, but they were not set to do so. The box has both USB2 and 3.0. I have tried to switch the connections back and forth with no luck. Has anybody experienced this before? Am I missing something? I don't have the time to really search in depth for the correct setting. Any ideas are appreciated.
