I've got a USB joystick that I'm having lots of trouble with. The
buttons all work fine but the directional input is problematic. I think
the problem is that he X/Y axes send values of 0 for Left/Up, +127 for
Center, and +255 for Right/Down; however, the range of the joystick is
detected as being from -127 to +127, and +255 gets interpreted as -1.
I've tested this with several kernels, inlcuding the latest stable
(2.4.14.3). I've also tested it in Windows 2000 where it behaves properly.
TIA,
Garron
