Hi ! 

I  have some questions about GPIO_122. 

In datasheet  DM3730_Technical Reference Manual I found that GPIO_122 (pic.below):

But in source of WinCe. In platform.c  I found unexpected comment , that this GPIO_122 is included in USB OTG. When I  change mux_mode from 0 to 4. I set GPIO_122 as gpio, but my device didn't connect to PC host. (pic.below)

Can we explain me which function had on GPIO_122? 

Thanks a lot !
