USB controls peripheral devices in a master/slave relationship.
It is hot-pluggable, eliminating the need to turn off or restart the computer when attaching a new peripheral. USB also provides power to the bus, enabling many peripherals to operate without the added need for an AC power adapter. The high-speed USB 2.0 features a maximum transfer rate that's forty times faster than USB 1.1, 480mbps. Intel's new motherboard chipsets for Pentium 4 processors will include the new USB 2.0 standard and Microsoft supports USB 2.0 in Windows XP.
