Just installed Windows 7 on my late 2012 27" iMac with 1TB fusion drive.  Went pretty smoothly.  Once the installation was complete I proceeded with the Windows Support install, which also seemed to go smoothly.  Got the message that I needed to restart for the changes to take effect so I did, and now my USB ports seem to be dead (in Windows only, OSX is fine).  I get stuck at the login screen with no way to do anything but hit the power button on the back and shut down.  I've removed all external devices and my USB hub and directly connected just the mouse and keyboard to the iMac, but that didn't work.  Restarted a few times with no change.


Any ideas?  Should I scrap the install, remove the bootcamp partition, and start again?

iMac, OS X Mountain Lion (10.8.2), [Late 2012][27"][1TB Fusion Drive]
