AM1808 USB2.0 as peripheral mode

Hi 

    We have custom AM1808 device and i need to enable the USB2.0 in peripheral mode but there is no initialization part in board file.

Please let me know what is the procedure to activate USB2.0 as peripheral mode which means i just want to connect the device with PC. 

1.Schematic

2.Board file

3.Kernel driver config

Thanks
