Micro-USB is a variant of the USB-B connector. The whole point of A and B was that A ports were used on the "host" system, and B were used on the peripheral. If you remember USB On-the-Go, that was an attempt to reverse the trend and allow a USB-B device (including micro ports) to act as a host.
USB-C erased that distinction in favor of a full duplex network connection between two hosts.
- lxgr 3y agoUSB-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.

- Dylan16807 3y ago> Micro-USB is a variant of the USB-B connector. In the same sense that A and B are variants of each other, sure. Even though it's called micro-B, the design is closer to A, and micro supports both ends with basically the same plug. I would never refer to it as just "B". "B" means the square plug.
