USB Micro-B

These are very similar to their Micro-A counterparts. These connectors are usually found on parallel devices. Compatibility exists between USB 3.0 Micro-B plugs and USB 3.0 Micro-B receptacles and receptacles of USB 3.0 Micro-AB only.

Specifications of USB 3.0

USB 3.0 has been modified in several ways to fulfill the huge demands of peripheral devices. Some of the unique properties of USB 3.0 are mentioned below.
