IKsNodeControl Interface

The IKsNodeControl interface must be implemented by USB Video Class (UVC) extension units. A UVC extension unit is a COM object that provides extended functionality to a USB video device, beyond the functionality provided by the UVC class driver.

The IKsNodeControl interface is used by the KsProxy filter to communicate with the extension unit. Applications do not use this interface. For more information, see the topic "USB Video Class Extension Units" in the Windows DDK.

In addition to the methods inherited from IUnknown, the IKsNodeControl interface exposes the following methods.

Method Description
put_KsControl Provides an instance of the IKsControl interface to the extension unit.
put_NodeId Sets the node identifier for the extension unit.
