The problem is that the gamepad then gets assigned the type
XTYPE_UNKNOWN which excludes it from all run-time code path switches.
Ah sorry for the noise. xpad_probe() already takes care of detecting
the gamepad type for the XTYPE_UNKNOWN case.
And this works for my Xbox 360 pad - not sure what's wrong with jstest,
but that is unrelated.
Ah okay good, that's what I was expecting.

To avoid that confusion, how about

I like this idea. There's a small risk of causing userspace breakages for
games matching "Generic X-Box pad" by name, but we already run that risk
each time we update xpad_devices[] anyway. You might even consider dropping
"Generic" from the name and just call them "Xbox One gamepad" or similar.

Can you also replace "Generic X-Box pad" with NULL in xpad_devices[]? I
don't think it would ever be used anymore after this change.
