I was referring to the HOST-ONLY mode available on the other USB pins, used for 3G. The external port is OTG, and can be switched between multiple modes. It may not have the connection needed to detect a host mode OTG cable, in which case you would need a software OTG mode-switch program (like the Nook Simple Touch hack uses).
