Nov 7, 2016 at 16:29 comment added goldilocks @Ghanima I have a stack of Android devices here from various big names that will work as OTG hosts and they all follow the same pattern: micro-B jack. So obviously the industry did not really go with the microAB type receptacle -- possibly because that jack is square and the big ones are confusing enough having to peer into to determine which way is up so you don't snap something.
Nov 7, 2016 at 16:08 comment added Ghanima By the book (An OTG product must have a single micro-AB receptacle and no other USB receptacles.) an OTG device should have an micro-AB (and not an micro-B) jack and the OTG cable should have an micro-A plug (not an micro-B). The Pi however has an micro-B jack and the adapters that ship with it have a micro-B plug. It would seem that neither the Pi nor other devices really care about the spec. So your answers seems to be right - in the real world.
