USB uses two wires to supply power and two wires to transfer signals. The following data transfer rates are supported:

Performance	Attributes	Applications
Low-Speed: 1.5 Mbits/s	Lower cost Hot-pluggable Multiple peripherals	interactive devices: mouse, keyboards, game peripherals
Full-Speed: 12 Mbits/s	Low cost Hot-pluggable Multiple peripherals Guaranteed latency Guaranteed bandwidth	phone, audio, compressed video, printers, scanners
High-Speed: 480 Mbits/s	Guaranteed latency High bandwidth	video, mass storage

Note

• SuperSpeed - 5 Gbits/s - is not covered in this document.
