USB - Universal Serial Bus was born out of the
need to provide designers and end-users with:
• an alternative to Apple's 1394 digital link
standard (FireWire )
• a fast, bi-directional, low-cost,
dynamically attachable serial interface
• that removes the port availability
constraints for the PC and other devices
