activate "unknown controllers"
and show a warning to the user to check and reassign controls
Background: Most Controllers are recognized already. If a (gamepad) controller is not recognized a fallback to "Gamepad Template" happens. For some reason some - especially china controllers - are recognized as joystick instead. Joysticks are not comparable to gamepads in manner of axes so the profile "unknown controller" is applied. Those are not supported until now.
