Forum Post: The AM335X(beaglebone black) usb0 as otg driver

Hi,

Recently,our team  use the beaglebone black 's otg(miniAB) port to be the host or slave device,I use the Linux kernel is Linux-3.2.0-psp04.06.00.11 ,And my configure is below:

And i insert the g_file_storage.ko or g_mass_storage.ko like usb wiki.

But when I insert my otg device(My otg device is the ID port connect the GND),My beaglebone black will print the error log:

"ti81xx_interrupt 1146: VBUS error workaround (delay coming)".

I don't change the board-am335xevm.c file,so I want to ask whether I must change the board-am335xevm.c file,and how to change it to realize the otg function.
