Logitech Quickcam Pro 4000

I am using 2.6.32-ARCH (64-BIT) on a Shuttle SP35P2 with Quickcam Pro 4000.

Followed the instructions on the arch webcam setup wiki (http://wiki.archlinux.org/index.php/Webcam_Setup.  When i try to test using gstreamer-properties, using v4l2 just displays testing but no picture and when using v4l the picture freezes and i see these kind of entries in dmesg:

pwc: isoc_init() submit_urb 0 failed with error -28
pwc: isoc_init() submit_urb 1 failed with error -28

running lsusb:

Re: Logitech Quickcam Pro 4000

Hi I had the same dmesg output using a Philips SPC 900NC.

The problem in my case was, that I connected the camera through a usb hub.

When connecting it directly to my pc it works perfect.

Good luck
