USB requires a host controller whereas IEEE 1394 is cooperatively managed by the connected devices. USB was developed subsequently and gained much greater market share. FireWire is also available in Cat 5 and optical fiber versions. Power and data is carried over this cable, allowing devices with moderate power requirements to operate without a separate power supply. The copper cable used in its most common implementation can be up to 4.5 metres (15 ft) long. It is also known by the brand names i.LINK (Sony), and Lynx ( Texas Instruments).
