Computer Hardware Terms, Glossary and Dictionary

USB 2.0, an enhancement of USB 1.1, is a high speed external bus that supports data rates up to 480Mbps. USB 2.0 is fully compatible with USB 1.1 and uses the same cables and connectors. Not all USB 2.0 devices are Hi-Speed. A USB device should specify the speed it will use by correct labeling on the box it came in or sometimes on the device itself. The USB-IF certifies devices and provides licenses to use special marketing logos for either "Basic-Speed" (low and full) or High-Speed after passing a compliancy test and paying a licensing fee.
