Unable to Use Bluetooth Mighty Mouse or Wireless Keyboard with Boot Camp
This trick seems to work reliably if you have a Bluetooth device that pairs fine in OS X but not in Windows:
- Boot into Mac OS X and go into the System Preferences -> Bluetooth pane.
- Rename the troublesome device.
- Remove the troublesome device.
- Boot into Windows and pair the device. (This should now work, because the renaming and removing in OS X gets the device back into a state where Windows will pair with it.)
- Boot back into Mac OS X and connect the device, re-pairing it if necessary.
After this, the device should work fine in both OS X and Windows.
The devices may have exited discovery mode before Windows was able to complete the pairing process. I've had this problem happen before and the best thing to do is turn everything off and on again and go through the process as quickly as possible. You may have also had a problem with the mouse and keyboard thinking it was already paired. This might have happened because the computer's bluetooth device is identified by an id address. If it were already registered the headphones may be trying to connect while the PC is trying to pair.
