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 cannot find any examples of this kind of port, can you share a link?

It is one of these connectors: https://en.wikipedia.org/wiki/USB_hardware#USB_On-The-Go_connectors https://en.wikipedia.org/wiki/USB_hardware#USB_On-The-Go_con... But every OTG device I have ever used has just used the USB-A port.

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! https://www.guru3d.com/miraserver/images/reviews/soundcards/H320////H320-bottom1.jpg https://www.guru3d.com/miraserver/images/reviews/soundcards/... 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)

  Another example of mini-AB is the TI-84 series. Two calculators can be directly connected but a USB A-A cable is verboten by the spec (although I sometimes see them nonetheless), so TI put an AB port on the calculator and sold a mini-A to mini-B cable. It is somewhat confusing to users that a cable with two different ends was nonetheless completely transposable. I'm not sure of this at all but I sort of doubt the TI-84 used spec compliant OTG, because in general the USB implementation on that calculator was very weird and unreliable and gave the feeling that they were doing something uncouth like bit-banging and not quite fast enough. I remember it routinely taking multiple attempts to get something to transfer successfully.
