That's true, but in this case I am 99% sure that's just Windows 7 glitching. I've seen that message on boards that don't even have a hub. G1 Sniper 3 and UD5H rev 1.0 use the same hub. I had this message on Windows 7 which didn't cause any connected USB device to shut down. It also disappeared after driver updates, and I've never had it on Windows 8.
