I'd be very glad to have a new subdriver in the gspca (framework?).

Sorry for I had no time enough yet to write a documentation...

The principle is that all the v4l2 API and kernel stuff is done by the
main module, and the subdrivers have only to do the exchanges with the
USB devices.

You may look at a simple subdriver as stk014 to know how to create your
own private structure, and how are realized the exchanges with the main
driver. If the images come through bulk messages instead of isochronous
messages, look also at the finepix subdriver.

Once done, you will remain the maintainer of the subdriver. Updates
could be then done either via my mercurial repository or by a new
mercurial repository created for you at LinuxTv.org.

Don't hesitate to ask me for any question.

Best regards.
