This article describes the steps needed to configure a Zotac remote control for Kodi/XBMC under Linux.

In the original configuration of Kodi/XBMC in Ubuntu the remote control works at all but several buttons on the remote control e.g. the colored buttons are not recognized by Kodi/XBMC.

This guide was created and tested on the following system:

Kodi/XBMC Forum

Build and install Lirc from source code

Download and unpack the source code from FernetMentas github repository. If unsure how to do this, please read the Forum thread mentioned above. 

 zbox:~$ sudo apt-get install wget unzip dialog checkinstall
 zbox:~$ mkdir src
 zbox:~$ cd src
 zbox:~/src$ wget https://github.com/FernetMenta/lirc/archive/master.zip
 zbox:~/src$ mv lirc-master lirc
 zbox:~/src$ cd lirc

Now start actually the configure and build process. 

 zbox:~/src/lirc$ ./autogen.sh
 zbox:~/src/lirc$ ./setup.sh

(requires package dialog, select driver zotac, save & configure) 

 zbox:~/src/lirc$ make

Generally it is not the Debian/Ubuntu way to run a make install. Using checkinstall from the package with the same name is a better way. This utility asks for some information and after that generates a Debian/Ubuntu package from the install process. This package may easily become uninstalled using the package manager apt-get purge lirc-zotac. 

 zbox:~/src/lirc$ sudo checkinstall make install

Configure UDEV

There are two goals of this UDEV rule. First create a link pointing to the correct /dev/usb/hiddev? device. Second it sends a message to the Upstart script that the device is available now.

Create a UDEV rule in file /etc/udev/rules.d/10-ir.rules. It differs from the content of the original article. If using the SUBSYSTEM=="usb" the created link from this rule /dev/remote points to something like /dev/bus/usb/003/002. It seems that lircd cannot handle that device but needs a device like /dev/usb/hiddev?.

The output of 

 zbox:~$ udevadm info --attribute-walk --name=/dev/usb/hiddev1

showed that a rule containing SUBSYSTEM=="usbmisc" will produce the correct link. It is strongly recommended to not hardcode the /dev/usb/hiddev<num> device in the other config files. On my system the device gets nearly on every reboot a different number. 

 # /etc/udev/rules.d/10-ir.rules
 # vim:set ft=udevrules:
 #
 # remote control 0471:2168
 SUBSYSTEM=="usbmisc", ATTRS{idVendor}=="0471", ATTRS{idProduct}=="2168", SYMLINK+="remote", ACTION=="add", RUN+="/sbin/initctl --quiet emit --no-wait ir-ready"

Configure System Startup

Configure Upstart

 # content of /etc/init/lirc.conf
 # vim:set ft=upstart ts=2 sw=2 et:
 
 description "lirc"
 emits "lirc-ready"
 expect fork
 start on (remote-filesystems
           and local-filesystems
           and started rsyslog
           and ir-ready)
 stop on runlevel [!2345]
 
 pre-start script
   while [ ! -e /dev/remote ]
   do
     sleep 1
   done
   mkdir /var/run/lirc
 end script
 
 exec /usr/local/sbin/lircd -H zotac -d /dev/remote --output=/var/run/lirc/lircd
 
 post-start script
   ln -s /var/run/lirc/lircd /dev/lircd
 end script
 
 post-stop script
   rm /dev/lircd
   rm -rf /var/run/lirc
 end script

Configure SYSV init

After Upstart isn't default init system anymore, the following simple script in /etc/init.d/lirc will do the job: 

  #! /bin/sh
  
  ### BEGIN INIT INFO
  # Provides:          lirc
  # Required-Start:    $local_fs $remote_fs
  # Required-Stop:
  # X-Start-Before:    rmnologin
  # Default-Start:     2 3 4 5
  # Default-Stop:
  # Short-Description: Provide support for Zotac remote control
  # Description: Provide support for Zotac remote control
  ### END INIT INFO
  
  . /lib/lsb/init-functions
  
  N=/etc/init.d/lirc
  
  set -e
  
  case "$1" in
    start)
      mkdir /var/run/lirc
      /usr/local/sbin/lircd -H zotac -d /dev/remote --output=/var/run/lirc/lircd
      ln -s /var/run/lirc/lircd /dev/lircd
      ;;
    stop)
      killall lircd
      rm /dev/lircd
      rm -rf /var/run/lirc
      ;;
    *)
      echo "Usage: $N {start|stop}" >&2
      exit 1
      ;;
  esac

  exit 0

Configure Xorg

Create a file /usr/share/X11/xorg.conf.d/09-zotac.conf with following content. It is not recommended to edit the file /usr/share/X11/xorg.conf.d/10-evdev.conf what recommend other guides, because this file is overwritten during every Xorg update.

This configuration section tells Xorg not to configure the remote control device as a keyboard. 

 # content of /usr/share/X11/xorg.conf.d/09-zotac.conf
 # vim:set ft=xf86conf ts=2 sw=2 et:
 Section "InputClass"
   Identifier "PHILIPS OVU710023"
   MatchProduct "PHILIPS OVU710023"
   MatchIsKeyboard "true"
   Option "Ignore" "true"
 EndSection

The exact name of the device differs.

The following command could help to discover the correct name: 

 zbox:~$ dmesg | grep hid-generic
 [    2.590261] hid-generic 0003:0471:2168.0001: input,hiddev0,hidraw0: USB HID v1.11 Keyboard [PHILIPS OVU710023] on usb-0000:00:14.0-1/input0

Configure Kodi/XBMC

configure and test

While testing keymaps it is often helpful to activate the changed keymap without restarting Kodi/XBMC. There is a XBMC event ReloadKeymaps to handle that. Either you could assign that command to a key on the remote or on the keyboard 

 <remote>
   ...
   <mykey>ReloadKeymaps</mykey>
   ...
 </remote>

or you can send it from the command line: 

 xbmc-send --action=reloadkeymaps

Eventually you have to install the xbmcsend utlity before (here the Ubuntu way): 

 sudo apt-get install xbmc-eventclients-xbmc-send

  </lircmap>

Test, Debug and Troubleshooting

There are different Levels to check if all is going well. To check if Lirc is going well you could use the irw utility. After starting that with root rights it should show a message for every key press on remote control. 

 zbox:~$ sudo irw
 0000000000070051 00 KEY_DOWN zotac.conf
 0000000000070052 00 KEY_UP zotac.conf

Problems with the USB device you could detect in the log file at /var/log/lircd. Correct handling looks as follows: 

 ...
 zbox lircd: lircd(zotac) ready, using /var/run/lirc/lircd
 zbox lircd: zotac initializing '/dev/remote'
 zbox lircd: accepted new client on /var/run/lirc/lircd
 zbox lircd: removed client
 ...

To check if Xorg and Kodi/XBMC are configured correctly you have to enable debugging inside Kodi/XBMC system settings or using command line 

 zbox:~$ xbmc-send --action=ToggleDebug

After that you should see the following messages in the XBMC log file after every keypress on remote control: 

 zbox:~$ tail -f .kodi/temp/kodi.log
 ...
 12:58:44 T:139757977200576   DEBUG: LIRC: Update - NEW at 2594:0000000000070051 00 KEY_DOWN zotac.conf (KEY_DOWN)
 ...
 12:58:52 T:139757977200576   DEBUG: LIRC: Update - NEW at 3409710:0000000000070052 00 KEY_UP zotac.conf (KEY_UP)
 ...

The most important thing is that 'zotac.conf' in these lines. Otherwise the remote control device is handled by another driver (e.g. inputlirc) and you will not be able to use all remote buttons.
