Can't get LIRC to work on Feisty

[tranquillion]

Hi,

I followed the instructions at https://help.ubuntu.com/community/Install_Lirc_Feisty to install LIRC for my Hauppauge remote. However, when I start irw for testing purposes, irw is exiting right away, so according to the instructions some modules are not loading correctly. The relevant lines from dmesg are:

[   50.156492] lirc_dev: IR Remote Control driver registered, at major 61
[   50.172942] lirc_pvr150: no version for "lirc_unregister_plugin" found: kernel tainted.
[   50.218763] lirc_pvr150: chip found with RX and TX
[   50.219440] lirc_dev: lirc_register_plugin: sample_rate: 0
[   50.231127] lirc_pvr150: firmware haup-ir-blaster.bin not available (-2)

I'm not planning to use the IR blaster, but I don't know if the missing firmware causes the module to fail. Any pointers would be appreciated!

Thanks
Klaus

If you aren't planning to use the blaster, there is no need to build the pvr150 module. Just need the lirc_i2c module. Rebuild with just that and you should be fine.

Ok, thanks; I removed pvr150 in both the dpkg-reconfigure dialog, and in /etc/lirc/hardware.conf. Now the only lirc-related message I see in dmesg is

[ 53.879014] lirc_dev: IR Remote Control driver registered, at major 61

However, irw still exits immediately... any suggestions where to look for the problem?

Thanks
Klaus

You should still be getting a lirc_i2c module loading, can you attempt to modprobe it.

sudo modprobe lirc_i2c

Oh, maybe I've read the instructions at https://help.ubuntu.com/community/Install_Lirc_Feisty wrong! I took the MODULES line literally from the instructions for the pvr-150 on-card blaster and added only lirc-dev and lirc-pvr150. Now I realize that this probably activates only the blaster, and I should also have lirc-i2c in there. Is that correct?

I'll try this when I get home...

Thanks

Or is this a simple misprint in the instructions? Should the line in /etc/lirc/hardware.conf read

MODULES="lirc_i2c lirc_pvr150"

?

It should be

MODULES="lirc_i2c"
if you don't need the blaster.

MODULES="lirc_i2c lirc_pvr150"
if you do need the blaster.

Thanks! I've updated the documentation.

I also got stuck at the point where irw does not work as described in the guide. I fixed it by quiting lircd if it is running (note that if you try to run irw and it returns with no response, it will also stop lircd if is running). Then I did the following:

sudo ln -s /etc/lirc/lircd.conf /etc/lircd.conf

Then start lircd with:

sudo lircd -d /dev/lirc/0

the irw command should now work as expected and you can continue with the procedure.

Lircd will have to be started using the sudo lircd -d /dev/lirc/0 command after a reboot unless you get it to load that way at boot.

I found most of this information at:

I don't know if this will work for everyone but it worked for me in edgy and feisty...

If you are stuck using these workarounds, then you don't have the init script from the ubuntu lirc package installed. You are using an init script from a source tgz typically.
