I have no clue if this would even work or is possible, but here's what I was just thinking while being bored at my desk.
I have a usb extension cable. usb female on one end and male on the other...etc. do they make double female usb ended cables or could you rewire one and then plug in a flash thumb drive in one end and the droids usb to micro on the other and hook it into the droid?
Would the droid detect it at all assuming the cables worked? Could you mount it and use it? could this be programed to work at all? or perhaps there already is adapters to do this I don't know.
Prob a stupid idea, but as I said I'm bored and i just happen to have this extension sitting in front of me on the desk and I was like hmmmm.
