Well as far as I can make out the OTG cable I am using should be pulling pin 4 to ground always.
So the Edison has seen voltage on the USB_ID line and decided that the USB was no longer OTG.
So unless there is a software issue it should mean faulty cable.
Perhaps it could be worth hacking the minibreakout to pull the USB_ID line low. Assuming I would always want it to be OTG.
