+kinect-audio-setup makes audio input from the Microsoft Kinect Sensor
+device work on GNU/linux systems.
+
+When the Kinect is first plugged in the USB port it shows up as a
+generic USB device with a bulk endpoint; after uploading a certain
+firmware a reenumeration takes place and a USB Audio Class device
+becomes available.
+
+kinect-audio-setup provides tools to download the firmware off the net
+at installation time —since it is not redistributable—, and it sets up
+udev rules to call the firmware loader when the device is plugged in to
+finally get the USB Audio Class device.
+
+Note that for all the magic to happen automatically pulseaudio >= 1.0 is
+needed, as it contains the kinect-audio.conf profile which fixes audio
+device detection:

+
+kinect-audio-setup provides:
+  - kinect_fetch_fw which downloads and extracts the firmware from the
+    Microsoft Kinect SDK;
+  - kinect_upload_fw which loads the firmware to the generic USB device
+    in order to get the USB Audio Class device to show up;
+  - udev rules to call kinect_upload_fw when the device is plugged in.
+
+
+To install kinect-audio-setup from the source distribution follow the
+steps below with superuser rights:
+

 Install kinect_upload_fw first:
 
 Install kinect_upload_fw first:
 

-  $ make install
+  # make install

 
 

-Then run the firmware download script:
+Then run the firmware fetcher script (remember this is only needed
+once):

 
 

-  $ ./kinect_fetch_fw /lib/firmware/kinect
+  # ./kinect_fetch_fw /lib/firmware/kinect
