Hi,

I know that iMX6 has a OTG enabled USB controller and I would like to know if an API is available to change the role of the USB controller dynamically from host mode to device mode.

I expect to call this API from user space.

After calling the API I exepct the USB host stack to go down and the USB gadget stack to come up.

Thank you.

Salvatore
