• History

  USB technology was originally introduced in 1995 as a means to all multiple devices connect to computers or each other using a uniform connector. The first version, USB 1.0, allowed a maximum speed of 1.5Mbps to 12Mbps. A second version, USB 2.0, was released in 2000 allowing a maximum speed of 480Mbps. A USB 3.0 version is currently in the works and is expected to be available to consumers in 2009 or 2020. USB 3.0 will allow ten times the speed of USB 2.0, a maximum of 4.8Gbps.
