You won't need a driver. Just plug the base station thingy in to the PC,
press the "connect" buttons (if there are any), and it'll work.

Same for me, for my wireless mice, I've used several,
you press a link button on the base USB unit, and a
button on the mouse, then it works, no driver needed.
Possible causes of problems
Range - plugging the dongle into the back of the
case, where it is shielded by the cases metalwork,
is not a good idea, use a USB extension to put
the receiver nearer the mouse.
Low battery power, particularly with the 2 x AAA
battery versions.
Rechargeables with a USB cradle, these can suffer
from insufficient charge. It only charges when the
PC is on, but then you are using the PC and the
mouse is out of its cradle and not charging.
Best solution I've found is a 2 x AA mouse,
2500mAh NiMH batteries, and fitting a
power cube to deliver 10mA charging current,
even when the PC is off.
