I have a similar problem with a Creative Optia webcam. I have found that removing the ehci_hcd module and reinserting it fixes the problem. If your kernel ships with ehci_hcd built-in (F11 and later), the script included also fixes the problem (it rebind the device). Of course, I'd love to see this issue fixed. Phil.
