Is it possible to use the included usb cable and plug in a female to female usb adapter to make it a camera connector?

No, I thought of the same thing, but apparently that won't work. Apple made sure of that so they could bilk you of another $29.

Lol I expect apple did that to stop crazy sods stuffing all sorts of random items into the socket, toasting the machine, then demanding a free replacement.........
