Yes, I'm sure, that ID pin is routed properly. It is also not BBB, but real device Baltos iR 5221 (http://visionsystems.de/produkte/baltos-ir-5221.html). With 3.15 I'm able to use OTG port both as device and host. I boot the device, insert FTDI based hardware into OTG port and my ttyUSBx devices, then disconnect and connect to PC and I get usb0 network interface and can communicate with PC.
