+Routine Description:
+
+    Worker routine called to create a device and its software resources.
+
+Arguments:
+
+    DeviceInit - Pointer to an opaque init structure. Memory for this
+                    structure will be freed by the framework when the WdfDeviceCreate
+                    succeeds. So don't access the structure after that point.
+
+Return Value:
+
+    NTSTATUS
