"USB has a maximum bandwidth of 12 Mbps for USB 1.0 and 1.1 and 480 Mbps for Hi-Speed USB 2.0. Up to 127 peripheral devices can be attached to the bus, and USB 1.1 devices can plug into USB 2.0 ports. Fast devices can use the full bandwidth, while low-speed ones can use a 1.5 Mbps subchannel." -- via Answers.com

There is a caveat,USB 2.0 has a theoretical max speed of 480 Mbps; however, in the really world it is usually half that speed.
