Is there a reason ekiga was not already installed?
Could you unplug the usb cord, then plug it back in. Then run

dmesg | tail

and post the output?

Ekiga was not found installed in kubuntu.the command output is
dinesh@dinesh:~$ dmesg | tail

hmmm. not exactly what I expected to see. You may need to temporarily disable usb 2.0 to get it to work. try :

sudo modprobe -r ehci_hcd

Then repeat the unplugging/replugging of the cam, and try an application...you may need to reboot. If you must have usb 2.0 re-enable:

sudo modprobe ehci_hcd

EDIT: ehci_hcd may get reloaded during boot. I'm not sure if sudo rmmod ehci_hcd will solve that...you many also be able to disable usb 2.0 in your bios.

[dineshs]

sir can you explain,because I am a beginner.

[spiderbatdad]

The kernel loads modules to provide functionality to the operating system. I am asking you to try disabling one of the modules that gets loaded.

 sudo modprobe -r ehci_hcd

Then try unplugging and replugging your cam again. If it doesn't work, enable the module:

sudo modprobe ehci_hcd

and try again. Sometimes removing and adding the modules is enough to fix the problem.

It didnt help.
During trial and error I had installed easycam2.It displays microdia usb2.0 webcam12.But ekiga says no device found

[spiderbatdad]

during configuration for ekiga did you select v4l2? Good luck. Maybe someone else will chime in. Also search google. Kubuntu may have some bug or workaround necessary.
