I have the exact same webcam; my computer is a Dell XPS M1530. For quite some time I have not been able to use my webcam with the Video4Linux drivers, which I wanted to because they seem to have more active development.

I found out that this webcam is supported by another driver, UVC Video. There is a list of the supported devices here, and it includes the webcam you mention.

Use your webcam with UVC Video

Each of the commands shown here you have to run in a terminal window.

1. Check if you have the driver by running $ sudo modprobe uvcvideo.

   • If you get an error saying FATAL: Module uvcvideo not found., then you should follow the steps in this Ubuntu Community Documentation article to install the module. After you're done, retry this step.

2. Check if other drivers are loaded, that are conflicting with uvcvideo: Run the following commands:

   • $ sudo modprobe -r videodev
   • $ sudo modprobe -r v4lTab (repeat this command for every entry listed when you press Tab).

3. Unload and load back again uvcvideo by running:
   $ sudo modprobe -r uvcvideo && sudo modprobe uvcvideo.

4. Open Cheese or any other application that will allow you to view through your webcam to see if you are getting video.
5. If this worked, you should blacklist videodev and make uvcvideo load everytime you boot.
   • To blacklist videodev run the following command:
     $ sudo echo blacklist videodev >> /etc/modprobe.d/blacklist-local.conf
   • To enforce the load of uvcvideo on every boot, run this other command:
     $ sudo echo uvcvideo >> /etc/modules

Comment

I only wrote this guide because this is how I got this problem fixed in my case; however, I don't know whether each of the commands I cited are mandatory or optimal.

Try this:

sudo apt-get install guvcview
