I'd start by downloading the latest test driver, alsa-driver-1.0.14rc3.
There have been a lot of changes to the usb audio recently.  That would
be a good starting point.

As to developing drivers, I couldn't tell you where to start.  The base
for snd-usb-audio is already in place, I'd look it over an get an idea
how it works, then see about getting specs for your sound device to add
to this base.
