The device drivers that support video capturing on Linux is called Video4Linux (V4L), and the latest version of V4L is V4L2 (the second version). You need packages from V4L to use the USB UVC camera modules. The easy way is to use software that supports V4L, like the VLC media player.
Since the camera operations is similar on different Linux distributions, you can also refer to this page about using webcams on Ubuntu if you need more help than this doc can offer.
