SRU Justification:

 * Plugging in a SB Arena USB headset or a number of other usb
   headsets causes the current window to hold focus, and prevent other
   windows from being selected essentially making the desktop unusable.

 * Without this patch users are forced to not use these devices.

 * cherry picked from upstream commit
 * This fix was arrived at via bisection, and has been verified in
 * Fixes the button mappings for the volume control which shows up as a
   hid device which is attached to the headset.


 * Create 2 windows
 * With focus set on one of them
 * Plug in the headset
 * Attempt to change focus using the mouse to the other window.
 * User will not be able to select focus on the other window.

Patches for Quantal and Precise attached.

Ack for the patches. Although should affect only users of HP keyboards,
not sure everyone on the bugs has the same issue.

Appears to already have been applied. Updated bug accordingly.
