STMicroelectronics Joystick in FS Mode
$cat /dev/input/mice
Returns funky text when I move spinner or trackball. Used to identify device #
$ cd /dev/input
$ ls -la
Returns mouse0 with only spinner plugged in to USB. When I plug in the track ball I also see mouse1. This 0 or 1 index is very important when assigning controls. The thing is unplugging and re-plugging into usb can change these mouse #'s. Especially if we put into a different USB Port.
On fresh Boot with both plugged in Trackball moved to mouse0 and Spinner to Mouse1.
$ cat /dev/input/mouse0
$ cat /dev/input/mouse1
Move trackball or spinner The # will correspond to mouse #.
Spinner goes in Bottom Left
Trackball into Upper Left
Joystick bottom right
Servostick top Right.
Do this to attempt to preserve mouse index.
