help!! my wired controller isnt recognized by games.

Fatal error
The game has crashed and will now close.
DXGI_ERROR_DEVICE_REMOVED
The GPU device instance has been suspended.
a fighting game crashed once when i plugged it in mid-session. Windows sees the controller, and the test page in the game cnotrollers panel responds to buttons. But games act like nothing is there. It started after teh Maximus V GENE Intel USB 3.0 Driver update from ASUS. Is there a way to see which input API the game uses and why it's not getting the controller?
