I thought OTG was just changing up where the host controller is sitting in the USB relationship? So you can have a device that acts like a client when hooked to a computer, or a master when hooked to a thumb drive/webcam/etc...?
Yeah it just allows you to use a B port as a host (if supported). It's still the USB protocol.
AFAIK, according to the standard you still cannot use the B port as a host, it should instead be an AB port (a socket in which both A and B plugs fit).
I had an iRiver H320 with USB-OTG support. At the time I thought it was just a straight-up mini-B port but you're right, that's actually a mini-AB port!

I am not sure I have ever seen mini-A anywhere.
God, what a wacky standard. (USB-OTG specifically but really USB plugs in general)

It is one of these connectors:

But every OTG device I have ever used has just used the USB-A port.
