Abstract
A method is provided for extracting device status information from a device which includes an IEEE 1394 interface. Said device is instructed by a device status information tester connected to said device to execute device self tests and to provide corresponding self test results and device specific information for said device status information tester, wherein said reading and instructing procedures between said device status information tester and said device are performed on the basis of a low level communication protocol of said IEEE 1394 interface.
