Also referred to as
Hi-Speed USB, USB 2.0 is an external
bus that supports data rates up to 480
Mbps. USB 2.0 is an extension of
USB 1.1. USB 2.0 is fully compatible with USB 1.1 and uses the same cables and connectors.
Hewlett-Packard, Intel, Lucent, Microsoft, NEC and Philips jointly led the initiative to develop a higher data transfer rate than the 1.1 specification to meet the bandwidth demands of developing technologies. The USB 2.0 specification was released in April 2000.
