Module Name:
Driver.cpp
Abstract:
This module contains the implementation of the Biometric
core driver callback object.
Environment:
Windows User-Mode Driver Framework (WUDF)

Routine Description:
The FX invokes this method when it wants to install our driver on a device
stack. This method creates a device callback object, then calls the Fx
to create an Fx device object and associate the new callback object with
it.
Arguments:
FxWdfDriver - the Fx driver object.
FxDeviceInit - the initialization information for the device.
Return Value:
status

// Call the device's construct method. This
// allows the device to create any queues or other structures that it
// needs now that the corresponding fx device object has been created.
