I've been searching for a driver for my old webcam in order to be able to use it in Vista. It appears that it's not supported anymore and the driver's not in Windows Update or on Philips support pages. You can get a driver updatePro

en Philips Vesta Pro (PCVC680k) and Vista = works! I've been searching for a driver for my old webcam in order to be able to use it in Vista. It appears that it's not supported anymore and the driver's not in Windows Update or on Philips support pages. Webcam Philips PCVC680K (Vesta Pro), Bus 001 Device 016: ID 0471:0308 Philips (or NXP) PCVC680K Webcam.

Pcvc680k from there, but it needs the original Installation CD, which I have probably lost. So I decided to isolate needed files from my Windows Server 2003 installation and try to use them on my shiny new Vista Ultimate. Guess what? It worked! Don't know how legal it is to share such files, but what the hell. Here they are. ;)
Good luck!
