Type-A 3.0 to Mini-B adapter
A USB Type-A (SuperSpeed) plug on one end and a Mini-USB Type-B socket on the other. This converts a port rather than carrying a signal any distance, so it is usually a stubby dongle rather than a cable.
- Mini-USB Type-B is obsolete - introduced 2000 and superseded in 2007. Expect a thinner, cheaper and more variable selection than for current connectors.
USB Type-A (SuperSpeed) — plug
The same rectangle as Type-A, with a blue tongue and five extra pins.
How to recognise it
- Identical outline to a normal Type-A - it is the same plug.
- The plastic tongue is usually blue; teal or red means a faster or always-on port.
- Five extra contacts sit behind the four you can see on a 2.0 plug.
- Maximum speed:
- 5 Gbps, or 10 Gbps on a USB 10Gbps port
- Maximum power:
- 4.5 W standard
Mini-USB Type-B — socket
The fatter, older cousin of Micro-B. Cameras and MP3 players.
How to recognise it
- About 7 mm wide but noticeably deep and chunky compared to a Micro-B.
- Trapezoid outline with a rounded, almost bulbous profile.
- If it looks like a micro plug but will not fit, it is probably this.
- Maximum speed:
- 480 Mbps (Hi-Speed)
- Maximum power:
- 2.5 W standard
