I evaluated several of these a few years ago for a client, and concluded the customer was better off with a smart contoller...

  In your DDK installation directory ,there is a folder called SRC which contains the source code for different drivers (audio/video/printer etc). Also it contains a ddksamples.chm which explains about each project and how to compile. This will help you to start the development.
