The Windows USB video class driver

In 2003, Microsoft added a standard USB video class (UVC) driver, Usbvideo.sys, to Windows XP as part of SP2. It is also included in all installations of Windows Server 2003 and Vista. This means that if you have a webcam or other video device that has a USB device driver that conforms to the USB video class specification, you can just plug it into your computer and it will work! No driver installation necessary. Any video device that has the “Designed for Windows Vista” logo must have a UVC compliant driver. The really cool thing about the UVC driver is that it is not just provided on Windows, but also on Linux and Mac OS-X, so a video device that complies with this spec will work anywhere!
