The Logitech QuickCam Pro 4000 is a great camera, but it is hard to get working. Ubuntu 6.10 (Edgy) includes the pwc kernel module driver that is supposed to work with this camera.

 # uname -a
 Linux noah-kubuntu 2.6.17-10-generic #2 SMP Tue Dec 5 22:28:26 UTC 2006 i686 GNU/Linux

The driver is broken in this kernel. You will see only a black or gray image with xawtv or camorama. The solution is to download and install the latest driver from http://www.saillard.org.

The pwc-10.0.12-rc1 driver works with Edgy Ubuntu 6.10. INSTALL.en taken from saillard:

1) download the file pwc-10.0.12-rc1.tar.bz2 (or the last available file on the site)

   wget http://www.saillard.org/linux/pwc/files/pwc-10.0.12-rc1.tar.bz2 pwc-10.0.12-rc1.tar.bz2

2) unpack the file using the command command:

   tar xjf pwc-10.0.12-rc1.tar.bz2

3) compile the module (this needs the source of your actual kernel to be installed)

   cd pwc-10.0.12-rc1

4) login as root


5) In case an older version of the module was already installed, use the following commands to delete that module, if not go to 6)

   find /lib/modules/`uname -r`/ -name "pwc*.ko*"
   rm <name of the file.ko>

6) Copy the new modules to the old ones

   make install


   cp pwc.ko <path to the folder of original pwc.ko module>
   For example: /lib/modules/`uname -r`/{misc,extra}
   depmod -a

7) Unload the old module(s) (or reboot the machine)

   rmmod pwc
   rmmod pwcx
   modprobe pwc
