This can be made to work. Please read the following thread http://old.nabble.com/USB-OTG-port-power-issue-with-webcam-to28492360.html#a 28510479 about needed SW changed, since OTG officially only supports USB devices asking for a maximum current draw of 100mA during enumeration. This you might need to "hack"...
