+/*++
+ 
+  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
