Creative Live Cam Notebook does not work on Ubuntu

After 3 months with Ubuntu, the only thing that I cannot get working is the Web Cam.

The camera is: Creative Live Cam Notebook.

I have installed linux-headers-2.6.22-14-generic.

After that I installed “gspcav1-20071224.tar.gz” from this link

To do this I have followed the instructions from help.ubuntu

Then the lsusb output is:
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 002: ID 046d:c03e Logitech, Inc. Premium Optical Wheel Mouse
Bus 003 Device 003: ID 041e:4068 Creative Technology, Ltd
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

I have also created a group named “video” and I have added myself there.

When I try to connect to camorama or kopete it shows the error message “could not connect to video device (/dev/video0)”.

What could be wrong?

Thanks in advance!
