[pwc] Quickcam Zoom and Playstation 3

[Prest Alessandro]

Hi everybody,
I'm trying to use a quickcam zoom (silver) on a Playstation 3 (which 
runs FC5 PPC).

I have some problem using the driver. I can mout pwc and I see 
/dev/video0 but as soon as I try to read from the camera lot of errors 
occurs.
The errors are pretty the same described by user "Raymond" in post 
"[pwc] Difficulties with a QuickCam 4000 Pro and USB2.0 hubs" (march 2006)

The playstation 3 has only usb 2.0, so I tried removing module 
"ehci_hcd" in order to make the ports to become usb 1.0, but the result 
it's the same (while this trick worked for "Raymond").

Any suggestion?
Thanks in advance
