Under Ubuntu 10.04 are these the last lines from dmesg when I plug the
Creative webcam in :

But here with Ubuntu, the Logitech cam does not seem to work. Unplugging and
re-plugging shows this in dmesg :
[  684.648065] usb 5-1: USB disconnect, address 2
[  684.648286] gspca: disconnect complete
[  689.485026] usb 5-1: new full speed USB device using uhci_hcd and address
3
[  689.682151] usb 5-1: configuration #1 chosen from 1 choice
[  689.685151] gspca: probing 046d:092f
[  689.744119] gspca: probe ok

In Ekiga in de Video Devices (when both cams are plugged in), I can choose
out of : Camera (PTLIB/V4L), Unknown/Generic (PTLIB/V4L) and Unknown/generic
(2) (PTLIB/V4L). But in Ekiga I have no camera image.

In Skype 2.1.0.81 the Creative Webcam 5 works as /dev/video2. When I click
on the Test button I get an image.
