There are a few common problems that can crop up when using different types of control-
lers on your Pi. The most common one, is that you just can't seem to get your game to re-
cognize any input. Your first step should be to check /dev/input and ensure that there is
a jsX (where x is the joystick number) file in the directory.
If you see your jsX file, type jstest /dev/input/jsX . You should now be able to
press the buttons on your controller and see the different input.
