PURPOSE: A device and a method for supporting standby mode of a complex network device are provided to directly request the standby mode change to a PDO of a USB complex device driver, thereby using a USB selective standby function about the USB complex network device in a Window XP. CONSTITUTION: A network device driver transmits an IDLE request IRP(I/O Request Packet) to a PDO(Physical Device Object)(263). The PDO transmits the IDLE request IRP(I/O Request Packet) to a bus driver(265). The bus driver transmits a IDLE Callback message to a network device driver through the PDO(267,269). The network device driver registers the active mode chanve Callback to a FDO(Function Device Object)(271). The network device driver transmits a Setpower D2 to a complex network device(273~277).
