I have a P4P800SE mobo. Here's the link:

When I tried to boot my computer after getting back from the holidays, nothing USB will work! Thinking it might be windows, I reinstalled with no luck. Anything I plug into the sockets seem to be getting power but windows just doesn't recognize it.
Going into the device manager, it shows all the USB root hubs and host controllers as functional and operating.
Does this sound like a mobo problem? I can't think of anything else to check...
