+Using the DFU loader–Windows
+============================
+
+Set up the image loader
+-----------------------
+
+#. Open the DFU Console Window from the Thesycon folder on the Start menu
+   (Program Files>Thesycon>USB Audio 2.0 Class Driver EVAL>DFU console).
+#. change directory to where the files have been extracted.
+
+To check the device has been detected, run the following command in the DFU
+console:
+
+  ``dfucons info``
+
+The console shows the DFU devices that have been detected.
+
+Download new firmware
+---------------------
+
+To program the new firmware run the command:
+
+  ``dfucons download usb_audio_class1.bin``
+
+Note that once this is done the device restarts as an XMOS audio 1.0 device. The
+original factory default audio 2 application is still present but the device is
+now running the upgraded application firmware.
+
+You can check the device has been updated by running the command:
+
+  ``dfucons info``
+
+This will display the device revision.
+
+Uploading existing firmware from the device
+-------------------------------------------
+
+You can retrieve a firmware image from the device, providing an upgrade image is
+present.
+Run the command:
+
+  ``dfucons upload currentfirmware.bin``
+
+The file ``currentfirmware.bin`` contains the latest upgrade image. This file is
+an exact copy of the data from the flash and can be downloaded to the device
+again to test.
+
+Reverting firmware to factory image
+-----------------------------------
+
+To revert the device back to its factory (i.e XFLASH) installed state from the
+new firmware, run the command:
+
+  ``dfucons revertfactory``
+
+The device will now only contain the factory firmware and will be running as an
+audio 2 device again.
