Upgrading LIRC package from https://launchpad.net/~commandir-team/+archive

deb http://ppa.launchpad.net/commandir-team/ubuntu intrepid main

2. Install drivers as root, or sudo:

Download the CommandIR hardware.conf (also configures MythBuntu Control Panel):

(wget command is 1 line ending with the '/etc/lirc/lircd.conf')

wget "/downloads/CommandIR II Resource Files/commandir-lircd.conf" 

  -O /etc/lirc/lircd.conf

apt-get update
apt-get install lirc

Unload old CommandIR kernel modules, if you are upgrading:

rmmod commandir

rmmod lirc_cmdir

Try some test commands with 'irw' or 'irsend'.

3. (If needed) To reconfigure your remote and/or blasting devices open up the MythBuntu Control Centre:

from the MythTV main menu select:

• Utilities / Setup
• Setup
• (scroll down) MythBuntu  

4. Restart MythTV, or reboot.

Troubleshooting

"No remotes work"

The most common problem is an LIRC bug when your selected remote files in hardware.conf are not included properly, and thus no remotes work.

If the running lircd manually test (plus irw in another window) yields output like this:

user@mythtv:~$ sudo lircd -n --driver=commandir

lircd-0.8.4a[4086]: lircd(commandir) ready

lircd-0.8.4a[4086]: accepted new client on /dev/lircd

lircd-0.8.4a[4118]: Child Initializing CommandIR Hardware

lircd-0.8.4a[4086]: CommandIR driver initialized

lircd-0.8.4a[4118]: Product identified as CommandIR II

and the "A" LED has changes to GREEN when 'irw' is also run - but pressing buttons on a remote only causes the CommandIR II remote LED to blink 'red' and not 'green', then try putting all your relevant lircd.conf's into the master /etc/lirc/lircd.conf. 

eg:

mv /etc/lirc/lircd.conf /etc/lirc/lircd-backup.conf

cat /usr/share/lirc/remotes/hauppauge/lircd.conf.hauppauge >> /etc/lirc/lircd.conf

cat /usr/share/lirc/transmitters/motorola/dctxxxx.conf >> /etc/lirc/lircd.conf

cat /home/mythbuntu/Desktop/lircd.conf.commandir >> /etc/lirc/lircd.conf

Then restart the test. 

Note, the PVR-150 lircd.conf (with "one    0  0" and "zero   0  0" lines) is specific to Hauppauge cards and not compatible with CommandIR!  Use the generic lircd.conf.hauppauge, which has the signal timings, instead. 

The 2nd most common problem is MythBuntu automatically loading the CommandIR Mini driver when a CommandIR II is plugged in:

Symptoms are 'lircd --driver=commandir -n' reporting:

  "Unable to read version request - Is CommandIR busy? Error -110"

or

 "lircd-0.8.4a[6064]: Unable to claim CommandIR - Is it already busy?

  lircd-0.8.4a[6064]: Try 'rmmod commandir' or check for other lircds"

Verify that none of these kernel modules are loaded:

- lirc_cmdir

- commandir

- lirc_dev

By running (as root):

rmmod lirc_cmdir commandir lirc_dev 

You can perminantly disable lirc_cmdir and commandir by blacklisting it, or deleting these files (MythBuntu 8.10):

echo "blacklist lirc_cmdir" >> /etc/modprobe.d/blacklist

echo "blacklist commandir" >> /etc/modprobe.d/blacklist

OR

rm /lib/modules/2.6.27-7-generic/kernel/ubuntu/lirc/lirc_cmdir/lirc_cmdir.ko

rm /lib/modules/2.6.27-7-generic/kernel/ubuntu/lirc/lirc_cmdir/commandir.ko 

To find these files on a different system, use:

find /lib/modules/`uname -r`|grep commandir.ko

1. To test on the command line (Terminal), try these commands:

1.1 irw

Running 'irw' should "freeze" while waiting for you to press remote buttons. 

If you receive 'connect: Connection refused' then LIRC is not running.

If irw returns/exists immediately, then LIRC is initialy running, but isn't configured for CommandIR.  Check your MythBuntu IR Devices settings, or manually install a preconfigured hardware.conf for CommandIR on MythBuntu from CommandIR Downloads:

/component/option,com_jdownloads/Itemid,53/task,view.download/cid,16/

If 'irw' freezes but doesn't display anything when you press remote buttons, double-check that LIRC has an lircd.conf for the remote you are using. 

1.2 irsend send_once <remote name> <button name>

Running 'irsend' should cause CommandIR to transmit the remote key.

If you receive the message:

irsend: could not connect to socket
irsend: Connection refused

then LIRC (lircd) is not running.  Check your MythBuntu IR Device settings and hardware.conf.  If you don't know the name of your remote or buttons, check out your lircd.conf file.

2. CommandIR II Light "A" goes red after a remote button press 

This can happen because:

• Old kernel module 'commandir' and/or 'lirc_cmdir' are loaded.  If running 'sudo lsmod' lists them, then remove them.
• Your LIRC isn't the latest, as of August 11, 2008
