I manually inserted mythtv into the /etc/group file and rebooted. Now the grep command gives the desired result, but the remote still doesn't work.
Do we know that udev works properly with serial port devices and LIRC?

The http://www.lirc.org/html/install.html page says the following

So, perhaps we need to copy this lirc.rules file as suggested?

Ok, from the beginning. Remove those last two lines in bootmisc.sh. They are not needed. The /etc/init.d/lirc script should load the module and start lircd. Doing it in bootmisc.sh too is going to cause confusion.

Diagnosing serial port receivers:

Reboot. First thing to check is the lirc_serial module loaded?


Next thing to check: Is it receiving a signal?
Then press buttons to see mark/space information. If you see nothing then you have a problem.

If that works, next thing to check is is lircd running?


Is lircd working?
Again press buttons and see if you get a line displayed for each button that you press.

Let us know exactly which check fails first.

It works fine with udev out of the box. I have tested this with my own serial receiver.

NOTE: All the hardware is plugged together the same as it was a few days ago when I was still running R5D1. In fact, it was never disconnected. Only the software has been changed.

OK. I removed the last 2 lines in the miscboot.sh file and rebooted.

This probably means that lircd has started properly and is using /dev/lirc0. That is good. But to test that your receiver is working properly, you want to stop lircd and then use mode2.
Then press buttons again and report what happens.

Thanks for your attention Greg. From my scanning of the forum, you are the LIRC expert, so I am in good hands!



Oh, I guess I hit the wall, here.

I wonder if my upgrade from R5D1 is the problem? I have the /etc/init.d/bootmisc.sh file as part of my restore files (in tjc's backup.list file).

Perhaps I need to get a "stock R5E50" version of the /etc/init.d/bootmisc.sh file? Does that sound reasonable? (can I extract this from the cd or can someone send it to me?)

I have sent you a bootmisc.sh.

Thanks very much! Logged in as root, and using nano, I just replaced the contents of my bootmisc.sh file with the version you sent me but left the last few lines as:
I rebooted and tried the tests that you suggested before and got no response from the mode2 command, again.
After that, I rebooted several times and tried the tests again - no change. After that, I decided I didn't like the bootsplash screen and decided to remove it from the system by undoing what the add_bootsplash.sh script does. Then, I decided to remove the serial cable and IR receiver from the Mythtv computer and move it to another computer to test it. The IR receiver worked with a virgin auto-install of R5E50 on the other computer. So, I moved it back to my main Mythtv computer and reran your suggested tests.
JOY!

It's working now. I wonder if an iffy connection on my serial cable was the problem all along? I hope not - after I stated that I was sure my hardware setup had not changed since I was running R5D1 just a few days ago.

The bottom line is that the LIRC is working correctly with udev and all the settings are as you said they should be.

THANKS FOR ALL YOUR TROUBLESHOOTING HELP Greg and tjc!

Eric

can you summarize your experience for others. Like what, if anything, did you end up changing from your original install. thanks.

Well, I'm not 100% sure what the problem was, but my theory is:

1. part of the problem was my using a backup-restored version of the /etc/init.d/bootmisc.sh file from my R5D1 install. I did an automatic install of R5E50 to a blank hard drive in a different pc (to test my IR receiver with a stock R5E50 install) and my IR receiver and IR remote worked fine after only restoring my custom-tweaked LIRC config files. So, replacing my old /etc/init.d/bootmisc.sh file, with the "stock" version from R5E50 seemed to be important.

2. part of the problem may have been the connection of my serial IR receiver. The serial cable may have worked itself loose when I was using my KVM switch during the upgrade process. The KVM switch is down on the floor next to my Mythtv computer. Unplugging and replugging the IR receiver may have been part of the fix.

3. I did manually edit the /etc/group file so that mythtv was the owner of the dialout group (see top of this thread page), but since a stock install of R5E50 didn't have this addition, I don't think it was important to fixing my problem.

Based on my experimenting, it looks like a stock install of R5E50 works fine with a serial IR receiver and IR remote, but an upgrade may not work if you try and restore too many system files from a previous version.

thanks. my /etc/group file didn't have mythtv as the owner of the dialout group after auto upgrade either.
I guess since you did a clean auto install and manually copied your /etc/init.d/bootmisc.sh that could have been the problem.

I think my lirc.conf and .lircrc files were copied automatically during the "auto upgrade", but i'm not sure about my bootmisc.sh

anyway, glad you got things working.
