Mom just bought a pc camera for me. I'm clueless! HELP!?

So my mom bought this little green and white box w/ a pc camera. at the lower right corner of the box it says Driverless Windows XP-SP2 VISTA. The back of the box explains all of it's features. Once I opened the box, I only found the little camera and the USB cord. Nothing else and no directions. So I plugged it into my computer and a little bubble came from the bottom of the page saying it installed the Vimicro USB Camera (Altair). Well, afterward I had no clue what to do next. I wanted it, so I could be able to chat w/ my friends on oovoo. But I don't know if i'm suppose to install a driver off the web, or if it's just good to go. Please help me get a clue. :)
