I recently bought a unibody 13" 2.4ghz Macbook and have had USB problems since the day I got it (only 3 days ago). Basically, whenever I leave the Macbook idle for a bit (not necessarily till sleep mode), the USB hub is inactive when I try to use it. It doesn't happen all the time, just intermittently. I've tried two different USB hubs, both have external power sources, which I've tried with it on and off to no effect. I've done all the updates, and I even remember one of the firmware updates being specifically about USB port issues. I'm at a loss of ideas right so suggestions would be appreciated, thank you!
BTW I've tried both USB ports and there was no difference.
