first guess here is that the ID_INPUT_JOYSTICK or some other tag isn't
applied by udev, so the rest of the system doesn't identify it correctly.
that could lead to e.g. the X server not initializing it. Usually the
solution to that is to either add a specific set of axes/buttons to trigger
the tag, or assign the tag manually with a custom rule.

What's the evemu-describe output of the device?
