Proprietary Kinect connector
My Kinect was purchased separate from the newer XBox, and was designed to work with the older units that did not have this connector.  As such, it has an adapter with the connector mating to what you have above, as well as a power supply and a standard USB connector.  I would suggest sourcing this cable and using standard USB.

First link I found... Niking store has it for &lt; 10 bucks and free shipping.
