You will most likely need the video4linux support libraries.

Check if you have them already.

 locate v4l1compat.so

In my case, the output is /usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so, yours might be different if you're on 32bit.

If it't not there, just install it:

sudo apt-get install libv4l-0

and try to locate it again.

Try to launch cheese with preloading the library

LD_PRELOAD=/usr/lib/your-path-to-lib/v4l1compat.so cheese

TLDP has some background information on shared libraries and their preloading.

first you have to check is the camera is attached
start the terminal by Ctrl+Alt+T then execute lsusb, do you see something like ?
