Abstract

A Universal Serial Bus node having a non-volatile memory is preprogrammed with the data bits necessary to configure an attached state machine to become a translator or modified translator for signals from a computer peripheral device. On startup, the Universal Serial Bus node is configured to translate signals to and from the computer peripheral device into USB protocol signals to and from a Universal Serial Bus equipped computer in order to assure proper communication therebetween.
