  • USB 1.x

    Released in January 1996, USB 1.0 specified data rates of 1.5 Mbit/s (Low-Bandwidth) and 12 Mbit/s (Full-Bandwidth). It did not allow for extension cables or pass-through monitors, due to timing and power limitations.

  • USB 1.1

    USB 1.1 was released in August 1998, fixing problems identified in 1.0, mostly related to using hubs.

  • USB 2.0

    USB 2.0 was released in April 2000 (now called "Hi-Speed"), adding higher maximum signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s or 280 Mbit/s), in addition to the "USB 1.x Full Speed" signaling rate of 12 Mbit/s

  • USB 3.0

    USB 3.0 was released in November 2008. The standard defines a new SuperSpeed mode with a signaling speed of 5 Gbit/s and a usable data rate of up to 4 Gbit/s (500 MB/s). A USB 3.0 port is usually colored blue, and is backwards compatible with USB 2.0

  • USB 3.1

    A January 2013 press release from the USB group revealed plans to update USB 3.0 to 10 Gbit/s
