Analog joystick on the PyGamer

I sometimes got apparent hangs on a PyGamer also when trying to use the “analog in test” program, the numbers simply stopped updating. This is inconsistent, just now it failed the first time I tried it, but then hasn’t hung again for the next several attempts.

Here’s my numbers:

center: ranges around -10 to 2,14 to 17
… and now it hung again as I tried to get readings.

Is there anything we can do to diagnose this or to help get this working more reliably? I’d love to add analog joystick controls to Space Rocks 3D.
