Apparatus and method for supporting suspend of composite network device

摘要

An apparatus and a method support a selective suspend mode in a driver for any one of at least two devices constituting a composite network device. When a device of the driver requests suspend mode transition, a Physical Device Object (PDO) constituting a driver of the composite network device is identified by a PDO check part. A suspend mode transition request information of the device is sent to an operating system through the PDO. When the operating system allows the suspend mode transition, a control part sends suspend mode transition indication information to the device through the PDO.

1. A method for supporting a selective suspend mode in a driver of a composite network device, the method comprising:
identifying a Physical Device Object (PDO) for a first device among a plurality of PDOs constituting the driver if the first device among a plurality of devices constituting the composite network device requests a suspend mode transition, the network device comprising the plurality of PDOs and a Function Device Object (FDO); sending an idle request for the first device to an operating system through the identified PDO without passing through the FDO; and sending a suspend mode transition indication information to the first device through the identified PDO if the operating system allows the suspend mode transition.
