lirc_zilog IR transmission no longer working with HD-PVR on 12.04

  • 772

I have been running a ubuntu 10.04 with a patched version of lirc_zilog for two years. I upgraded to 12.04 and lirc_zilog is no longer working with my HD-PVR. The MythTV wiki reports that it did work out of the box with 11.04.

The error message I get on irsend is as follows:

johnf@carbon:~$ /usr/local/bin/irsend SEND_ONCE blaster 0_130_KEY_POWER
irsend: command failed: SEND_ONCE blaster 0_130_KEY_POWER
irsend: hardware does not support sending

The lircd daemon, run interactively, reports the following:

 lircd: accepted new client on /var/run/lirc/lircd
 lircd: could not get hardware features
 lircd: this device driver does not support the LIRC ioctl interface
 lircd: major number of /dev/lirc0 is 250
 lircd: LIRC major number is 61
 lircd: check if /dev/lirc0 is a LIRC device
 lircd: WARNING: Failed to initialize hardware
 lircd: error processing command: SEND_ONCE blaster 0_130_KEY_POWER
 lircd: hardware does not support sending
 lircd: removed client

Checking dmesg seems to indicate that the kernel module is loading properly:

Here is my /etc/lirc/hardware.conf

 #Chosen IR Transmitter
 TRANSMITTER="HD-PVR"
 TRANSMITTER_MODULES="lirc_dev lirc_zilog"
 TRANSMITTER_DRIVER=""
 TRANSMITTER_DEVICE="/dev/lirc0"
 TRANSMITTER_SOCKET=""
 TRANSMITTER_LIRCD_CONF=""
 TRANSMITTER_LIRCD_ARGS=""

My lircd.conf is a copy of the recommended one.

Examination of the kernel source seems to indicate that the lirc_zilog module should support transmission, it's newer than the patched version I was manually compiling on 10.04. I was previously using a manually built version of lirc 0.8.7 and not the packaged one. I'm now running the packaged version 9.0.

I can provide any additional information required and will perform tests quickly. I'm very eager to get this issue resolved.

    That's odd...it works out of the box for me with 12.04.

    Why are you using /usr/local/bin/irsend instead of the one in /usr/bin/irsend?

    Here is an irsend command that works for me:

    /usr/bin/irsend --device=/dev/lircd SEND_ONCE blaster 1_27_KEY_2

    Perhaps you need to specify --device, and use the binary in /usr/bin?
