Repeatable Lirc Issue - no /dev/lirc0

Wondering if anyone here has anything to add to the thread below... I
noticed the thread as I fought through issues with Lirc yesterday (to
no avail), posted a reply to a thread that seemed identical to my
issue, and another person has since posted a "me too". Seems there
are at least 3 of us fighting the same issue on the same platform.

Platform: PVR-150, Ubuntu 7.0.4.

My best guess at the issue: No /dev/lirc0 is created when following
the instructions at:
https://help.ubuntu.com/community/MythTV_Feisty_Backend_Frontend_Desktop

Here's the thread at ubuntu forums:
http://ubuntuforums.org/showthread.php?t=487674&highlight=mythtv+lirc

Not looking to move the thread here and wasn't going to since it's not
a MythTv issue per se, but with 3 or more of us having the same issue,
I thought I'd just call out to see if some of the experience here
could help out.

Thanks much!

Bryce

I had similar problems getting lirc to work with Feisty. I finally
found these directions:
https://help.ubuntu.com/community/Install_Lirc_Feisty that solved my
problems.

My setup is a little different, I'm using a serial port IR receiver;
but I believe this will work for you.

No /dev/lirc0 means that your LIRC modules have not loaded properly.

# lsmod | fgrep "lirc"

will list all LIRC modules currently loaded. To use the PVR-150
on-card receiver, you need the lirc_i2c module loaded. To use the
on-card receiver *and* blaster you need to load the newer lirc_pvr150
driver.

Once the modules are successfully loaded, restart lircd, and, with a
suitable lircd.conf in place, irw and LIRC should start working. Note
you may have a udev rule for LIRC that creates both a /dev/lirc and a
/dev/lirc0 device. You just need to ensure that lircd is being started
with a device path that actually exists.

Re: Repeatable Lirc Issue - no /dev/lirc0 [In reply to]

Thanks to all those that replied...

I had reason to reinstall Ubuntu (new SATA controller, finally got
video card) since the last one was a test run of sorts...

Anyway, looks like
https://help.ubuntu.com/community/MythTV_Feisty_Backend_Frontend_Desktop
was updated and now calls out a Live CD install of Ubuntu 7.0.4 which
for a relative noob like me feels better anyway. Just yesterday, it
called out for the "Alternate" install.

Starting from scratch, it seems like that took care of it!

Thanks to everyone for their help. Wish I knew what it really was.
And that Zap2It would let me create a channel line up, even for 2
months...

Bryce
