I don't know precisely but I can get you started. First let's see if it's showing up in your hardware information. Open System -> Administration -> System Log -> Syslog or Messages (either one should show if a device is plugged in). Here's what it looks like in messages when I plug in my webcam:

And as you can see the device is properly detected. Granted, this is a webcam that is specifically sold for Skype and I have Skype on my machine so it works perfectly. Can you verify that your machine is detecting the hardware?
As you can see, the device is put
