I had a shot at something very similar to this recently but gave up! I’m not experienced enough in Linux to see it through to the end.

You could have a shot and see if you have any more luck. Here are the links to the pages I used:

Using UDEV rules to assign persistent names to joypads

As a rough guide, here are the steps I used:

lsusb

udevadm info –name=/dev/input/js0 –attribute-walk

and then use the information which is returned to create a udev rule (in /etc/udev/rules.d)

Good luck!
