it is not a straight wires-to-wires connection. An adapter/capturing device is needed for the connection. There are adapter cards that can be install in the computer that do this as well (not through the USB).
I was wondering if anybody has a diagram to make an AV to USB converter, I know the quality wouldn't be the best, but I have an old camera, that has no way to hook up to a computer. I just need where the wires hook from the AV to the usb and line in plugs.
