What is unique about the USB Type B 3.0 connector compared to earlier versions?

The USB Type B 3.0 connector is unique because it supports a feature known as "reversible" or "bi-directional" design. This means that the connector can be inserted in either direction, enhancing usability and convenience. This design mitigates the common frustration of trying to connect a USB cable in the correct orientation, which was a limitation in earlier versions of USB connectors that had a specific direction for insertion.

The advancements in USB technology with the introduction of Type B 3.0 connectors also incorporate enhancements in data transfer rates and power delivery, but the key distinguishing factor here is the ease of use brought by the reversible connector design. This improvement highlights the focus on user experience in modern USB versions compared to older iterations.
