I have a PMP device that uses a Rockchip RK27xx chip.
Currently it his hooked up to my computer via a USB cable and I want to create a program in Windows (Vista) to access and interact with it. I want it to return a list of files stored on the device, and add (and possibly delete) new files to and from it. It's very important to me I get this done and that it's all done from within the program.
I can't simply access it as a Generic Storage Device, both because the firmware isn't letting me, and because of the uses I want to put the device too I can't allow myself to use that as an option.
So I'm trying to figure out the best way to communicate with it, on every level from accessing the USB data, to sending commands, to having file level access of the main storage of the device.

EDIT: I apologise for posting in the wrong form. If it could be moved to the "Support and How To" forum that would be very helpful.
