TM4C129ENCPDT: Example of HOST mode using ULPI.

Part Number: TM4C129ENCPDT

I have not be able to get the external usb22.0 to woerk in HOST mode.

Does anyone have a working example of using a  external ULPI in HOST mode, as far I can tell, it simply does not work.

 Everything i try set the internal and external registers back to Device mode on Host session start.

Preferably with a USB3320 ULPI chip.

    Are you using custom hardware, or one of TI's development boards? Have you tried one of the USB host examples from TivaWare?

    custom hardware, 

     and there are no example of HOST mode using EXTERNAL ULPI that i can find, all the example I find arefor device mode with external ULPI.

    I have fully functional code using host mode with internal USB at full speed ,But it is external ULPI that refuses to function the same,

    the internal register imply that it switches back to device mode even though i set up for host mode.
