Does the parameter have to be called "mouse"? I'd rename it to "input"
and drop the work "class" from parameter description.

Please consider implementing mdps_input_open() and mdps_input_close()
and create and run the polling thread from there - there is no point
in polling the device if noone listens to its events.
