I'd definitely appreciate testers once I get some work done. Actually, if
you're on Linux, would you mind testing out the bit of code in the attached
file? You'll have to open a joystick device first in pyglet, then pass it
to the function. It'll should then give you an sdl2 style GUID. (I just did
some crude conversion of the available id_*s in pyglet, but I imagine there
might be a better way to get these values).
Also, whether or your Windows/Mac/Linux, would you mind sending me the
id_bustype, id_vendor, id_product, id_version, and name from your
joysticks? I've no idea if these are the same on other platforms, but I
will need to figure out how they get converted in any case.
Thanks!
