Hmmm looks about right, though that male A connector is not quite as nice as the female A that you'd really expect, so you'd need to attach a gender changer as well for most applications. Since that's marked as an "OTG" connector it might already have the appropriate pins shorted, though I'd be surprised as I don't get the impression that whoever designed it in the first place really had a practical application in mind for it.

Good idea on the marking the adapter so that people won't get it mixed up; one of the other guys here at the office is pretty creative when it comes to things like that so I'll see what the best permanent way we can come up with is.
