Accessing data from HID compliant USB device

Does the joystick produce keyDown/Up or rawKeyDown/Up messages? If so,
you could map out the numbers that each motion triggers and have your
app react accordingly.
There is a utility on my web site that detects keystrokes and displays
the various codes for them.
