USBB OTG ID pin management | |
The ID pin come from the USB OTG connector (A and B receptable) and allows to select the USB mode host or device. The USBB hardware can manage it automatically. This feature is optional. When otg_ID_PIN equals true in conf_usb_host.h, the USB_ID must be defined in board.h. | |
