How to configure USB OTG as host in Pandaboard under Android ICS

There is a group that is supporting pandaboard that could help with this kind of questions: pandaboard@googlegroups.com

Thanks for the reply, though i already asked there but i haven't get any answer and i'm kind of hurry on this :(, i don't know if in Pandaboard this is working under Android ICS.

Best Regards.

i do the following:

echo host > /sys/bus/platform/drivers/musb-hdrc/musb-hdrc/mode

and i got the following:
