could not connect /dev/video0 (webcam), what should i do?

I am working in Ubuntu 10.04 LTS - Lucid Lynx. My notebook is Samsung r720 with internal livewebcam (webcam SCB-1600). I have installed ubuntu all was ok, but a couple week ago my WebCam stoped to work.

When i tried to run camorama i have got "Could not connect to video (/dev/video0) Please check connection".

I checked on windows, all is working.

What i have to do to fix it?

ls -la /dev/video0 
andrew@andrew-laptop:~ $ ls -la /dev/video0
ls: can not access /dev/video0: No such file or directo开发者_开发知识库ry

Have you got any other video device (maybe just video, or video1: ls -la /dev/video*)?

If you haven't any other device, it most likely means your webcam isn't supported by your kernel. You should install (or load) the kernel modules (ie: drivers) for it.
