USB-OTG ports are technically mini-AB and micro-AB ports that can fit both A and B plugs.

And USB-C is neither full-duplex (at least not for USB 2) nor host-to-host; there is a protocol negotiation and some devices can never act as hosts, although some can indeed assume both host and device roles.

Even in a “host-to-host connection”, only one side will act as the host.
