The IMDSPDevice interface provides an instance-based association with a media device. Using this interface, the client can get a storage media enumerator for the device, get information about the device, and send opaque (pass-through) commands to the device. IMDSPDevice2 extends IMDSPDevice by providing methods for getting video formats, getting Plug and Play (PnP) device names, enabling the use of property pages, and making it possible to get a pointer to a storage medium from its name. This interface is optional for the service provider but is recommended.
In addition to the methods inherited from IUnknown, the IMDSPDevice interface exposes the following methods.
