ubuntu 11.04 - lirc init script sets invalid ir protocol for imon driver (imon Looks like you're trying to use an IR protocol this device does not support)

[Ash]

I have the following VFD + IR device...
Bus 002 Device 002: ID 15c2:ffdc SoundGraph Inc. iMON PAD Remote Controller

With the following installed versions...
kernel: 2.6.38-10-generic
lircd: 0.8.7
...and configured using the devinput driver (config generated via "dpkg-reconfigure lirc") I get this error in syslog and lirc fails to work:

kernel: [ 20.254591] imon 2-7:1.0: Looks like you're trying to use an IR protocol this device does not support
kernel: [ 20.254597] imon 2-7:1.0: Unsupported IR protocol specified, overriding to iMON IR protocol

Running lircd manually works...
sudo /usr/sbin/lircd -n --output=/var/run/lirc/lircd --driver=devinput --device=/dev/input/by-path/pci-0000:00:0b.0-usb-0:7:1.0-event

So to get lirc working when launched via the init script I have to comment out the in_kernel_support() function so that it doesn't try setting the incorrect protocol.

Status changed to 'Confirmed' because the bug affects multiple users.

I have been trying to diagnose an issue where my MythTV box (with an iMon LCD) occasionally hangs on shutdown. I have tracked the issue down to the lirc init script, and the line it freezes on is:-

  in_kernel_support "enable"

I still haven't figured out what this is function is doing yet, but searching has brought me here, and I also notice the following lines in dmesg:-

  imon 6-3:1.0: Looks like you're trying to use an IR protocol this device does not support
  imon 6-3:1.0: Unsupported IR protocol specified, overriding to iMON IR protocol

My device is "15c2:0038 SoundGraph Inc. GD01 MX VFD Display/IR Receiver" running on Ubuntu 11.04.

I have been trying to find out why my mythbox hangs on every shutdown. Checked a lot of components (even switching to GDM from KDM) to no avail.

Today I've found that it was the lirc process that hung. Disabling the in_kernel_support in the stop part of the stop/start script fixed the issue (like described here).

However: unlike the OP I am on 11.10 with all the latest patches installed.

Bug has been very annoying and almost made me switch to another distro. It would be nice if someone could fix it.

After a few years of happy Mythtv use I finally upgraded from Ubuntu 8.04 to 11.10 and came across this problem where my Antec Fusion case with this IMON unit (the non-remote control version) would not shut down after I got everything installed.

Was pulling my hair out for ages until I finally stumbled on this bug report. I have commented out the suggested section and now it shuts down nicely.

Thanks so much to the previoous posters for finding a workaround!

Thank you for providing a workaround, that was driving me nuts.

The new lirc version 0.9.4c (zesty) sports a much-simplified systemd setup which lacks this kind of initialization. Could you make a check with this new package? Please note that the update requires major configuration changes
