webcam Creative Go Plus not work

Hi all,
i have an old USB webcam Creative Go Plus.

I tried to connect it on my Pentium 4 with Ubuntu 9.04 but all software cannot recognizes it.
i tryied to use : Nautilus, gThumb, f-spot, Skype.

Althought, if i try to do:

$ lsusb
Bus 004 Device 007: ID 041e:4003 Creative Technology, Ltd VideoBlaster WebCam Go Plus [W9967CF]

i can see the webcam is present.

My first important step is to download the files (images/clips) to my PC and to clear the webcam memory.
Second step is to use it in skype.

In internet i found:
http://sourceforge.net/projects/winbond-webcam
but i worried to use it because it's a pre-Alpha software.
What do you think about it?

Thank you for patients.
