USB OTG Extension Cable and DAC
Solved! 

I went home and soldered a piece of wire between the two cut negative wires and now the extension cable works! I assume it has something to do with grounding out the ID wire in the micro usb. In anycase, SOLVED! Yay!

So as summary, I have an extension cable which allows my devices to get external power while still receiving signal from the tablet. The reason for this is to minimize power draw on the tablet and to extend battery life.
