Abstract

Retrieval of status information from a remote device performed on a host system is provided, wherein the remote device is connected to the host system via a bus system comprising at least two signal lines terminated with resistors on the host system side and on the remote device side. The retrieval method includes: activating a sensing phase; sensing the at least two terminated signal lines during the sensing phase; and determining operating state of the remote device based on the sensing result; wherein at least a first operating state representing a connected and powered remote device is detectable.
