Hi spacerox,
My suggestion is to download and install MacCam 0.9.2 (
http://webcam-osx.sourceforge.net/downloads.html ).
It is free and it makes work lots of webcam plugged to your Mac without the use of specific drivers.
The Philips TouUcam Pro II is listed within those supported.
You can have a look to the entire list from here
http://webcam-osx.sourceforge.net/cameras/index.php
Let me know how it goes.
Cheers.
