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]

    Search this forum. Bootcamp does not support fusion drives.

    This support article seems to indicate that it is not supported on 3TB Fusion Drive configurations only.  I have the 1TB.

    Can I add a Windows partition?

    You can create one additional partition on the hard disk with Fusion Drive. You can create either a Mac OS X partition or a Windows partition.

    I am having the exact same issue with a 21.5 iMac. Under Windows Safe Mode the wired USB keyboard works but the mouse still does not respond. If you find an answer please post

    I just reinstalled Windows and the support drivers again.  Before I let it restart I paired a bluetooth keyboard.  I also attempted to pair a bluetooth trackpad, but it wouldn't see it for some reason.  I also installed an iOS remote mouse/keyboard server as a backup.  Then I went and disabled a driver called Intel(R) USB 3.0 eXtensible Host Controller and another one that was similar but looked more like a hub.  I remembered seeing these fly by while the bootcamp support stuff was installing.  Despite these efforts, I am still at a loss.  My USB keyboard & mouse still dont work (or anything USB for that matter - although curiously the bluetooth adapter seems to be connected to an internal USB hub, and my paired USB keyboard was working ok and allowed me to login).  Anyway, I'm still not really sure what to do.  It's very frustrating.

    I have a 2012 i7 mac mini and just installed windows 7 ult 64 bit on to a second internal 1T drive, All went fine including installing the apple software but once I restarted I have no keyboard or mouse (both USB wired) If I boot into safe mode then they work, I tried to reinstall the apple software but get an error when in safe mode. I have tried unplugging everything els but the keyboard and mouse and still not working. The USB hub lights up like it is connected as well as a little light on my external microphone but no way of knowing if anything works as I can't log in.

    Has anyone figured this out yet?

    I just ordered a cheapo bluetooth mouse since my bluetooth keyboard worked.  It's not an ideal solution, but I hope it'll get me by until Apple finds and solves whatever USB driver issue this is.  Will post back if it works out.
