Where should I start looking for documentation? Do I need to read everything about IOKit? I'm a fairly experienced programmer and I have a newertechnology USB floppy disk drive that OS X does not have a built-in driver for. However it is recognized by System Profiler. I think it would be fun to write a driver for it, but I have no driver writing experience.

Check out the OS X documentation that's installed with xCode.

I wondered if there was anyone else out there with a uDrive.

Let me know if you have any headway ... I'll gladly beta test for you. (My programming skills are pretty much limited to PHP and VB, otherwise I'd volunteer coding as well)
