Open a konsole and run the command, 'sudo lsusb' ( without the quotes ). That will give you some output. What you need is the Vernder ID and Product ID. It will look something like this...
Bus 002 Device 002: ID 04f9:0028 Brother Industries, Ltd Printer
The example I show here is the my printer, however the camera should show up the same way. The 04f9 is the Vender, and the 0028 is the product ID. Once you have that, you can go looking for a driver. Here is one link to try:
This driver supports a lot of web cams. If that doesn't do it, Google the info. ie 'www.google.com/linux/whateveryouaresearchingfor'
Once you have identified what driver, look in Synaptic to see if it is included with buntu, a lot are.
You may have to load the driver with the modprobe command. So the will look like this: modeprobe thenameofthedriver.whatever
Then try your apps to see if it is working...
