-Module Name:
-
-    Device.cpp
-
-Abstract:
-
-    This module contains the implementation of the UMDF socketecho sample
-    driver's device callback object.
-
-    It does not implement either of the PNP interfaces so once the device
-    is setup, it won't ever get any callbacks until the device is removed.
-
-Environment:
-
-   Windows User-Mode Driver Framework (WUDF)

-/*++
-
-  Routine Description:
-
-    This method initializes the device callback object and creates the
-    partner device object.
-
-    The method should perform any device-specific configuration that:
-        *  could fail (these can't be done in the constructor)
-        *  must be done before the partner object is created -or-
-        *  can be done after the partner object is created and which aren't
-           influenced by any device-level parameters the parent (the driver
-           in this case) might set.
-
-  Arguments:
-
-    FxDeviceInit - the settings for this device.
-    FxDriver    - IWDF Driver for this device.
-
-  Return Value:
-
-    status.
