    try:
        # Retrieve the first USB device
        device = AlarmDecoder(USBDevice.find())

        # Set up an event handler and open the device
        device.on_message += handle_message
        with device.open():
            while True:
                time.sleep(1)

    except Exception, ex:
        print 'Exception:', ex
