DIRECTORY STRUCTURE-BASED READING OF CONFIGURATION ROM

摘要

A method of reading configuration ROM in a serial bus device reads only portions of the ROM that are organized in a directory structure. Typically, the configuration ROM follows the IEEE 1212 and/or 1394 standards and uses IEEE 1394 bus. Based on the information read from the configuration ROM, a connecting computer can determine the appropriate device driver to use for communications with the device.
