I have not been able to get the USB OTG port on my Sabre-SD card to work as a USB host. It clearly works when I get the MfGTools v2 working but I believe it is a client in this mode.
When I plug in my Belkin hub with a mouse and keyboard attached they are not recognized. Any help in getitng these up and running would be greatly apprecaited.

This is the one I used succesfully:
