UVC Stands for 'USB Video Class'. It defines video streaming functionality on the Universal Serial Bus. UVC compliant peripherals only need a generic driver; much like mass storage devices (USB flash disks, External disc enclosures, etc.) can be managed by a single driver because they conform to the USB Mass Storage specification.

UVC Linux Driver
The GNU/Linux UVC Driver page is at http://linux-uvc.berlios.de/ and includes a list of supported devices
UVC support in Ubuntu
7.10 and later
In 7.10 the UVC module has been included which means that some webcams 'just work' however UVC is still at an early stage and device support and bugfixes are being added all the time. It may well be necessary to update to the latest version to get your hardware to work, in particular Skype will only work properly if you have uvc version 166 or above, earlier driver versions freeze up after a minute or so with some cameras.
7.04 and earlier
UVC support is not included and you'll have to install it yourself.
Installing UVC
UVC has not released any 'snapshots' yet and has not been packaged and included in the Ubuntu repositories. There is a debian package located [url http://packages.debian.org/unstable/graphics/linux-uvc-source here] but the best way at the moment is to grab the latest build from the Subversion repository and compile it yourself.
Checkout from SVN
If you do not already have subversion installed get it with:
sudo apt-get install subversion
Then get that latest source from the repository with:
svn checkout svn://svn.berlios.de/linux-uvc/linux-uvc/trunk
This will make the directory 'trunk' containing the source in your working directory
Build
Make sure you have kernel header files. In Ubuntu 7.10 and later, you need the header files package specific to your CPU architecture, for example, linux-headers-2.6.22-14-386 in addition to just linux-headers-2.6.22-14. You can do this with:
sudo apt-get install linux-headers-`uname -r`
Navigate to the 'trunk' directory containing the source and run:
make
Install
Ubuntu keeps the kernel module for UVC in /lib/modules/your kernel/ubuntu/media/usbvideo and the makefile has to be altered slightly to install to the correct directory. Open the the makefile in a text editor and change :
INSTALL_MOD_DIR := usb/media to INSTALL_MOD_DIR := ubuntu/media/usbvideo
then run
sudo make install
Insert Modules
sudo modprobe uvcvideo
If you're running 7.10 this may complain that the module's already loaded. In that case unplug your camera and remove the old module with :
sudo modprobe -r uvcvideo
then insert the new one again as above
