You don't need to remove ukbd from kernel unless you want to use
uhidd's own keyboard "driver". Since it's a gamepad, you only need to
compile the kernel without uhid(4) and start uhidd with "uhidd -hs
/dev/ugen.X.Y". Then you can try something like "usbhidctl -f
/dev/uvhid0"...

However, uhidd doesn't have specific joystick/gamepad support at the
moment.  The only benefit of using uhidd on joystick/gamepad is:

1) split multiple joysticks using one endpoint (for converters, very rare).
2) strip the report id byte so usbhidctl and the userland usbhid(3)
   parser can support the device.
