I bought an IR receiver from manoweb.com a few days ago, so I'm trying
to get lirc and myth working, but am running into some trouble and I'm
not real sure where to turn. I believe I have lirc working correctly
because I can see that it is receiving codes from my remote. I
installed lirc from source, and ran irrecord to set up my remote. I
followed the documentation and also recompiled myth after enabling
native lirc support in settings.pro.
If I run irw I can see my buttons being received by lirc, but Myth does
nothing. I am also receiving one error when I run modprobe
lirc_serial. Here it is:
/lib/modules/2.4.22-28mdk/kernel/3rdparty/lirc/lirc_serial.o.gz:
init_module: Input/output error
modprobe: insmod
/lib/modules/2.4.22-28mdk/kernel/3rdparty/lirc/lirc_serial.o.gz failed
Starting Linux Infrared Remote Control daemon: [ OK ]
I also get this in the log:
Apr 17 10:44:41 darthmaul kernel: lirc_serial: auto-detected active low

Apr 17 10:44:42 darthmaul lircd: lircd startup succeeded
I'm not sure what this stuff about dev_fs is. I have /dev/lirc,
/dev/lircd, and /dev/lircmd and that's all. I set the following in
/etc/sysconf/lircd:
DRIVER=default
HWMOD=lirc_serial
# with devfs enabled -> not sure what this is
#DEVICE=/dev/lirc/0
# without devfs -> not sure what this is
DEVICE=/dev/lirc
COM_PORT=/dev/ttyS0
I have no prior experience with lirc, so I'm not sure what to look at or
how to get rid of the problems above. I can't tell because of these
errors if the problem is with lirc or with Myth not using lirc for some
reason.
I appreciate anybody's help or advice or pointers.
Thank you,
