+** Driver TODO: Complete the implementation of EvtDriverDeviceAdd for your specific device.
+**
+** WDF calls this callback when a device instance is added to the driver.  Good drivers will do a lot of
+** work here to set up everything necessary, such as adding callbacks for PNP power state changes.
+** This function defines an IO queue for handling DeviceIoControl and file read requests, both of which are
+** important to the POS barcode scanner model.
+**
+** Note that this is not a complete device add implementation, as the PNP power callbacks are not handled.
+** Additionally, driver writers may wish to set up additional queues to serialize device property requests
+** (see Ioctl.cpp for more info).
