Type-A 3.0 to Type-B 3.0 adapter
A USB Type-A (SuperSpeed) plug on one end and a USB Type-B (SuperSpeed) 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.
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
USB Type-B (SuperSpeed) — socket
Type-B with an extra storey stacked on top, almost always blue.
How to recognise it
- Looks like a Type-B that has grown a second chamber above it.
- Nearly always moulded in blue plastic.
- A plain Type-B plug will fit this socket; this plug will not fit a plain Type-B.
- Maximum speed:
- 5 Gbps
- Maximum power:
- 4.5 W standard
