I just upgraded from 6.04 to 7.1 and everything seems to have gone well except for losing my remote. I am currently using a Hauppauge PVR-150 card and IR receiver for my remote control.

I have searched and seen a couple of similar issues but nothing that is leading me tward a solution. It appears that the IR receiver hardware is not being detected. The tuner itself is working fine. I tried deleting and restoring the card but saw no improvement. irw is not registering any events. I saw that '/sys/class/rc/rc0' is not being created which finally led me to look at the logs.

tail /var/log/lircd
Jan 20 21:51:09 mediabox lircd: caught signal
Jan 20 21:51:13 mediabox lircd: lircd(default) ready, using /var/run/lirc/lircd

Jan 20 22:01:13 mediabox lircd: removed client

dmesg | grep -e lirc -e LIRC
[ 10.969734] lirc_dev: IR Remote Control driver registered, major 250
[ 11.009099] IR LIRC bridge handler initialized

To my untrained eye it appears that lirc is not seeing my hardware. If someone could point me in the right direction I would greatly appreciate it.

saw a couple of posts here about remotes not working in R7. I think the fix has to do with assigning the correct type of keyboard.

Update - I had already seen the posts you pointed me toward, and in each of them irw or mode2 would return results. I am seeing nothing.

So I just did a fresh install on a spare drive to see what would happen. I ran the install in no-splash mode. I saw that the hauppauge ir receiver was detected, but an error message was generated stating that myth was unable to create /sys/class/rc/rc0

$ mode2
mode2: could not get file information for /dev/lirc
mode2: default_init(): no such file or directory

I am at a loss.

I am perfectly willing to just throw money at the problem to get the spousal approval back, so does anyone know which IR receiver is guaranteed to work with 7.1? Hopefully something I can go pick up at microcenter.

Update - To rule out a hardware failure I pulled out an old PVR-250 and did another fresh install. Unfortunately I am having the same results.

Had a similar problem.

Quote:
The next problem I discovered was that my romote was not working.
Code:
Service Menu -> Mythtv Configuration -> Setup -> General -> Page 9(last page)

Changing 'lirc daemon socket' from /dev/lircd to /var/run/lirc/lircd

Covered in post - R7.1 upgrade PVR-250 remote /sys/class/rc/*/ missing? - Thanks again goofee!!


Fixed it for me.

Well, I found that I was combating 2 different issues. I made these discoveries on a fresh install of 7.1. First off, no variant of /dev/lirc was being created with my PVR-150 installed. I have no idea why, If I find an answer I will update this thread. The model number on the sticker is "ntsc/ntsc-j 26032 rev c199". The IR receiver on this card works fine with 6.04.

On to the second issue. I did another fresh install of 7.1 with my older pvr-250 installed. This time /dev/lirc0 was being created, but lirc was looking for /dev/lirc according to the error I received when I tried to run 'mode2'. So I created a sym link 'ln -s /dev/lirc0 /dev/lirc', then restarted lirc 'sv stop lircd' 'sv start lircd' and the remote was fully functional.

I then reconnected my upgrade installation. I verified that the PVR-150 was still not being properly initialised, as seen in the fresh install, but the pvr-250 did properly initialise. I also had to create the sym link as I described above, restarted lirc, modified the 'lirc daemon socked' to point to the correct location, and she came back to life.

Thanks for your help.

Same problem here - fresh install of 7.2 no remote - this soft link fixed it! Great work - thanks!

I just posted a bit more explanation about how lirc connects up at viewtopic.php?p=134047#p134047

It might be that the PVR-150 is using the devinput driver. you can check this by shutting down lirc and then using ir-keytables to see if you are ven getting anything from the driver.
