I once had the optimistic assumption that it would be possible to write code for devices which are not available to me for testing. With this intention in mind, I wrote up some instructions what data to record to be able to figure our the protocol by which host and device communicate (basically reflecting the experiments I made to implement the PODxt Pro driver):
http://www.tanzband-scream.at/line6/usblog.html Although it turned out to be very difficult to actually write code based on these data without being able to test myself, it might provide some hints for you. For the kernel part of the ALSA interface, you should read this: http://www.alsa-project.org/~tiwai/writing-an-alsa-driver/index.html For the USB stuff, I only used the documentation included in the kernel sources. Hope that helps, feel free to ask if you are looking for a particular piece of information!
