I am thinking that by connecting an OTG to the micro USB with a regular female USB connector on the other end I might be able to connect a keyboard or Bluetooth dongle. Probably overly optimistic, but maybe there is some hack that can be applied.
According to the Freescale documentation I have read, the OTG port does not support "Auto-Sense", at least on the K3.

You should be able to use a OTG **HOST** micro USB cable and manually do the remove and install of the kernel modules required to switch from device to host operation.

Amazon does sell such an adapter - listed for the K4 and the K5, without mention of the K3.

Another note -
The power available from the Kindle's OTG port may be less (maybe much less) than what can be expected from a standard USB port - since they did not build the hardware to by used this way.

Translation: Use a powered hub to provide power to the external devices.

Let us know how you get on with this -
This subject has come up here before.
