MatchIsJoystick only works on devices that are assigned ATTR_JOYSTICK.
config/devd currently only does so for joy(4) devices but not uhid(4) as
the latter isn't specific to joysticks. The proper detection may require
teaching it to speak usbhid(3) but for now see inlined patch at the end.
MatchIsJoystick is specified just like the following line. It isn't an
option passed to a X11 driver.
> MatchDevicePath "/dev/uhid*"
config/devd is a bit too pessimistic. Any device not in hw_types table
seems to be ignored by default, so MatchDevicePath may not be applied.
For one, config/udev only ignores non-ID_INPUT devices which translates
for USB into intclass=0x03 in devd(8).

FWIW, emulators/joytran maybe more useful for Wine unless all your games
have the same keybindings.
