Hmmm Mike when I use the locate command it just returns with no output.
IIRC the grey remote uses the lirc_i2c module the same as mine does,
so it's a question of checking to see if the modules is getting loaded
and if not then loading it and setting it to load at boot time. A
simple way of finding the module location is to grab a shell and do
locate lirc_i2:
Mike@P-733-Lin:/var/lib> locate lirc_i2
/lib/modules/2.6.27.19-3.2-pae/updates/lirc_i2c
/lib/modules/2.6.27.19-3.2-pae/updates/lirc_i2c/lirc_i2c.ko
/lib/modules/2.6.27.29-0.1-pae/weak-updates/updates/lirc_i2c
/lib/modules/2.6.27.29-0.1-pae/weak-updates/updates/lirc_i2c/lirc_i2c.ko
All that means is that it found no matches.
What I did originally was to cd into the directory with the moduleWhoosh! Sometimes Linux can give me a real headache! Ok I attempted to
file and then lsmod | grep lirc*, then modprobe lirc_i2c and then redid
the lsmod (why? well it's really the first time I had to load a module
and make sure it loaded every time at boot, so I wanted to see the
results as I progressed through this). IIRC insmod lirc_i2c is used to
have the module load every time, but I could be wrong, I was following
the far ranging advice of google.
follow your route and here is what happened -
nova:/var/lib # lsmod | grep lirc*
lirc_atiusb 14692 0
lirc_dev 11068 1 lirc_atiusb
usbcore 165556 8

So far that seems pretty good. I have one question. Will this be
persistent? In other words do I have to execute this modprobe command,
to load the lirc_i2c module, each time I reboot my computer? If so, is
there a script or config file somewhere that specifies what kernel
modules are to be loaded on boot up?
Darn I can't remember if it will or not, so I'll have to go back over
that, there is a config file for loading modules, but I have never had
to adjust it, either insmod or modprobe deals with that.
I Googled around and learned a bit
about loading kernel modules but nothing answered this question. Also,
how in the world is one suppose to be able to discover what kernel
modules are available on a system? This seems like a lot of insider
knowledge! Is there a tool (with a GUI to guide a poor soul) that helps
a user to configure the kernel with appropriate modules? I am looking at
all this output and just shudder at trying to understand all this!
have a look in /sys/module or /lib/modules/<uname -r>/kernel, and there
are other places, that I don't offhand recall.
Well further Google attempts and a visit to the LIRC website seemed toI also have an IR Blaster with runs off the serial port of the computer.
With this, I am going to want to control a Dish Network HD settop box
and a Harmon Kardon receiver. So I have run the IR transmitters to the
front panel of each, in front of their IR receivers. I have tracked down
a set of button code definitions for the Dish Network HD settop box and
appended them to the lirc.conf file (where I already have the button
code definitions for the Hauppauge 350 remote) I have not yet tracked
down the Harmon Kardon codes yet, so I may have to generate them myself
later.
You might want to subscribe to the mythtv mailing list for this info.
indicate that I need another module loaded in the kernel called
lirc_serial. However when I tried to load it I got the following surprise -
nova:/var/lib # modprobe lirc_serial
FATAL: Error inserting lirc_serial
(/lib/modules/2.6.27.29-0.1-default/weak-updates/updates/lirc_serial/lirc_serial.ko):
Device or resource busy
Interesting, I was just redoing this on my 11.1 system and got that
exact same message.
I dunno for sure what I am doing, so consider this as a bad guess on my
part? I will keep Googling but wowza am I getting in over my head? Sure
seems awfully complicated! If you (or anyone else) got any ideas, I sure
could use some....
Tell me about it. :( I'm seriously beginning to wish I had written
down the step by step I did. I too looked all over Puce and back before
getting it to work. (Of course my MythBuntu install did all of that
grunt work for me!!!!!!!!!!), all I had to do was start using it.
Didn't I just do that already? With the lirc_i2c module? Or are youYaST2 reports that I have the lirc-kmp-default and lirc-kmp-pae packages
already loaded.
So what we really need to do is determine which module drives the
remote, and get it loading, so google for the 350 and it's remote to see
what lirc module it needs.
referring to something else and perhaps I lost you...
Yes the 350 uses the lirc_i2c module, just like the 150 does. I
wasn't sure if that was the case when I said to Google it.
There are a few on this list using mythtv, and the best resource that
I've run across is Charles Philip Chan, who's helped me in the past, and
looking back at some older messages, you too, but I didn't see any
mention of which module you used for LIRC.
Yes, the wiki, I did not find much help in it, updating it would be
good.
Yes I have been down part of this path before, but it was so long ago I
have forgotten what I had done to get the Hauppauge IR receiver
working... That coupled with a computer crash that lost all the previous
configuration did not help matters any. So yeah I will try to capture as
much as I can on the wiki for future reference!!!
I hear ya, while I may well ditch oS as my primary desktop, there's no
reason other people shouldn't benefit from other peoples past
experience.
My next message will be dealing with the config files.
