You do not need a proper driver to get the webcam up and running because the camera takes advantage of the built-in webcam drivers and upon installing a new operating system (as it's stated on the official page : Windows XP & Windows Vista [32 bit version]) the webcam will install itself.
For a good clarification of things, I invite you to visit the official support link for your product and scroll down to Camera section. You will find a message saying what I have explained above.
