Web Cam

Okay I have a laptop, with XP Professional with all
updates even XP1a package.. I'm using Logitech Webcam pro
for laptops.. After talking with Logitech.. it seems my
USB Controller SIS 7001 PCI to USB ... and its not
working with the Logitech. camera.. seems I need a new
UHCI Host controller or QHCI host controller... is there
a fix for this? OR WILL i have to purchase an upgraded
USB upgrade card for my laptop? thanks..
