4.) Reverse engineer/disassemble the hardware access routines and
embed them in your own camera firmware that includes USB storage
commands. Probably about equal difficulty to option 3 (i.e., way
too much work) but gives you total control of the software when
you're done. Throw in one of Joseph's text to speech systems
while you're in there. (-:
I agree with Mike that #1 is the way to start, and I'll point to
Greg KH's slides from his Linux USB driver class. They make it
look like the process of driverizing working code is pretty
straightforward.
