Logitech QuickCam 4000 Pro USB webcam is detected but does not work on Debian 

  * The hardware works absolutely rightly on a Debian Lenny machine.
  * On Debian squeeze, I plug it in and tt is detected (/var/log/syslog or
    dmesg), /dev/video0 created. lsusb shows the new device.

      Bus 003 Device 005: ID 046d:08b2 Logitech, Inc. QuickCam Pro 4000

    However, even if it is detecte rightly,
      * 'ekiga' hang when cam is enabled.
      * 'cheese' shows black screen, both at photo and video mode.
      * 'xawtv' hangs when USB set as source of video.

Linux kernel changed a bit with how it deals with webcams, change from v4l to 
v4l2, but debian kernel should come with all the needed stuff.

Module "pwc" is loaded.

  * lsmod 
	pwc                    72006  0 
	videodev               29977  1 pwc
	usbcore               121703  9 snd_usb_audio,snd_usb_lib,pwc,

  * modprobe -r pwc && modprobe pwc

  /var/log/syslog shows the below lines. Nothing odd:

I think that is a Linux kernel problem. Is it specific to Debian or to the 
mainline Linux kernel 2.6.32?

Feel free to ask me for more testing, Linux kernel patching and so on. Also 
let me know if I am direct this bug report to the main Linux kernel 
development mailing list.
