Hi everyone, I'm running Windows 7 with boot camp on my unibody MacBook Pro. Quite often, I'll close the lid to put it to sleep, then, a few minutes later I'll notice that the Apple light has turned on, and when I open the lid I confirm that it's woken up. In Event Viewer, I've noticed that every time this happens, the following event is listed, in the Power-Troubleshooter category: "Wake Source: Device -USB Composite Device". I have no USB devices, ExpressCards, CDs, or anything plugged in. Any ideas? Thanks very much, Michael EDIT: It doesn't only happen when it's running on battery power, since it just happened with the AC adapter in.
