What does it do?

Modifies the default D-link USB capture device (1 audio/1 video) to extend the number of video inputs to 4.

Detailed Description

The default device for the id: 0x573:0x400 in usbvision is "D-Link V100"
I changed this to:

"4-input USB video suveillance", the usual name for this device.
It still can be used for D-Link, but just 2-nd and 3rd input (as Composite 1 and S-Video)

The inputs are renamed using the color of the connector (Green, Yellow, White, Red)
