+Description: Set the mode the ROG Ally xpad operates in:
+ - 1 = Game mode
+ - 2 = WASD mode
+ - 3 = Mouse mode
+ This setting applies instantly and applies settings that were previously changed
+ under that mode which are:
+ - deadzones
+ - anti-deadzones
+ - button mapping
+ - button turbo settings
+ - response curves
