I've seen ways to activate the USB OTG on the bionic though i have yet to try it. The OTG will not function if the device is not being powered. using a powered hub and connecting a USB Y cable through the device and drive is what seems to be the trick... a lil research and you should be able to find an easy answer. can't remember the web address to the site off hand but not hard to find. there is even some howto's to make a battery powered hub for on the go.
