Why each option
USB 2.0 introduced Hi-Speed USB with a maximum theoretical transfer rate of 480 Mbps, a major improvement over USB 1.1.
USB 1.1 supports a maximum of 12 Mbps (Full-Speed) or 1.5 Mbps (Low-Speed), far below 480 Mbps.
USB 2.0 (Hi-Speed USB) is specified at a maximum transfer rate of 480 Mbps. This specification was standardized by the USB Implementers Forum and remains the rated ceiling for USB 2.0 connections on both host controllers and devices.
IEEE 1394b (FireWire 800) operates at up to 800 Mbps, which exceeds 480 Mbps.
IEEE 1394a (FireWire 400) operates at up to 400 Mbps, which is less than 480 Mbps.
