try it in another usb port, should then come to life
this might be a bit obvious but does it have an on off switch?
if yes, is it turned on?
the lazer does no light up underneath,uninstall drivers and then re-install don,t know what win you using but there is a win 7 driver out now for it,plus have you pressed the infra red button on the mouse so it can sync with the docking station,think thats your problem.
Have you tested it wired?
