looks like it's not tagged as ID_INPUT_MOUSE by the default udev rules
because for that we need x/y axes (either relative for real mice or absolute
ones for the VMWare USB mouse). This keyboard only has buttons though. So it
gets ID_INPUT_KEYBOARD for the keys, but no ID_INPUT_MOUSE.

Google isn't overly forthcoming on "DELL Dell USB Entry Keyboard" but the
few pictures I can find all point to a keyboard that doesn't have any
physical mouse buttons at all. Does yours have buttons? Can you post a
picture of it somewhere?

Cheers,
