Game Controller on X9S

Not sure if I'm doing something wrong, or missing an enable somewhere, but none of the game controller I plug into the usb work.

I've tried an xbox 360 wired controller, an xbox 360 wireless controller (this uses an xbox360 wireless dongle for pc), a logitech cordless precision controller (also uses a usb dongle for pc). The wireless controllers seem to be connecting fine to the usb dongle attached to the x9s, but none of the 'gamepad supported' games work with the controllers.

I wouldn't...
