UMDF Device Object Creation and Initialization
Chapter 5 describes device callback objects
UMDF drivers create a device callback object that partners with a framework device object. The device callback object implements callback interfaces that the framework uses to notify the driver of Plug and Play and file-related events.
The driver callback object’s IDriverEntry::OnDeviceAdd method creates and initializes the device object. The framework calls this method with the following two parameters:
A pointer to the IWDFDriver interface on the driver object.
A pointer to the IWDFDeviceInitialize interface on the driver object.
The IWDFDriver interface defines the CreateDevice method, which the driver calls to create the framework device object. The IWDFDeviceInitialize ...
