ATI Southbridges + Creative Webcams = Nothing.

Let's start off with this from the Creative Knowledge Base:

"Solution ID # 17557

Creative WebCam Live! Ultra, WebCam Live! Ultra for Notebooks and Live! Motion and Certain ATI Chipsets

Summary:

* Creative WebCam Live! Ultra, WebCam Live! Ultra for notebooks and Live! Motion may be incompatible with some ATI southbridge SB400 and SB450 products.

All the listed Creative products are USB-IF certified. To learn more about USB-IF certification, please visit: http://www.usb.org/developers/compliance/

A PC System Configuration that has ATI southbridge SB400 and SB450 may have connection issues with the 3 models from Creative.
If you believe you are experiencing connection problems, we recommend:

1. Check with your PC motherboard manufacturer for a BIOS upgrade. or
2. If one is not available or does not resolve the issue, use a PCI to USB 2.0 or PCMCIA to USB 2.0 card.

If these steps do not address your problem, we would suggest returning your product to your retailer to exchange for a Creative Live! Cam Voice, WebCam Live!, or WebCam Live! Effects camera or alternatively a refund. Please contact Customer Support for further assistance."

And now, an angry response via a forum post from a former Creative customer:

CREATIVE PEOPLE: YOU DON'T CARE WITH YOUR CUSTOMERS. I WILL NEVER PURCHASE ANOTHER CREATIVE PRODUCT AGAIN UNLESS YOU SOLVE THE PROBLEM FOR THE CAM TO WORKS WITH USB 2.0! PLEASE STOP BLAME ATI CHIPSET! DON'T TELL ME YOU ARE *INCAPABLE* OF WORK AROUND THIS PROBLEM IN YOUR DRIVER. DON'T TELL ME TO BUY A PCMCIA CARD! SOLVE IT OR I WILL BE GLAD TO BLAME YOU TO CUSTOMERS THAT ARE CONSIREDING PURCHASE YOUR PRODUCTS!

With that I decided to create this petition: http://www.petitiononline.com/cwcamati/petition.html
