[Cbe-oss-dev] Some issues with a USB webcam on a PS3

[Andrea]

Hi,

I've tried to use a Logitech QuickCam 4000 Pro USB on my PS3 running Fedora 12
It does not work and in /var/log/messages I can see some errors

The first part is the driver failing to capture (I had already loaded it) and it might be buggy.

But the there is something I am not sure what it means:
Could it be a bug in the PS3 kernel?
