I have a late 2010 MBP 15 10.7.2 that will no longer boot up if any USB devices are attached. A dongle, a hub, anything. It goes to the gray screen and stays there. Disconnecting all USB devices the MBP will boot up. Then connecting the USB devices they work. It just will not boot up with anything connected to the USB ports. I have reset PRAM, SMC and fixed disk permissions. Made sure login items are ok, and start up disk is correct. I cant really say when the problem started as it worked fine before, maybe on 10.7.1? Not sure.


Any suggestions for a fix?

MacBook Pro, Mac OS X (10.7.2)
