Live Cam VX-6000 Resolution issue

Hi everyone!

I bought a LifeCam VX-6000 few weeks ago and the maximum resolution I got is
640 X 480. Well I downloaded the latest driver from the Microsoft website and
still no more result and that is not all I mean the picture is not even
clear. I got a big problem with pixilation. So I heard there must be a
compatibility issue between my Windows Vista the VX-6000 and my motherboard
wich is a Asus P5GD1. I just don't have a clue.
I hope someone can help me!

Thanks in advance!!!
