USB 2.0

Universial Serial Bus (USB) 2.0 is a complete overhaul of the Universal Serial Bus input/output bus protocol which allows much higher speeds than the older USB 1.1 standard did.

The goal of the new serial bus is to broaden the range of external peripherals that can be used on a computer.

Hi-Speed USB 2.0 has a maximum bandwidth of 480 Mbps. Up to 127 peripheral devices can be attached to the bus, and USB 1.1 devices can plug into USB 2.0 ports.

Fast devices can use the full bandwidth, while low-speed ones can use a 1.5 Mbps sub-channel.
