I'm trying to get a new installation of Mythbuntu working. So far, everything is OK except the remote. The sensor for the remote is on my Hauppauge WinTV HVR 1250.

First I tried to run irw to see what was being picked up by the sensor:

$ irw 
connect: No such file or directory

Then trying to run lircd gives:

$ lircd start$ lircd start
lircd: can't open or create /var/run/lirc/lircd.pid

I look for any lirc devices and find there are none:

$ ls /dev/li*
ls: cannot access /dev/li*: No such file or directory

Just to be sure, I check in /proc/bus/input/devices, which shows me two powerbuttons (not sure why), kbd and mouse dev, and the audio devs. Nothing for the IR receiver on the tuner card (which I thought was strange because shouldn't the tuner show up here?).

According to dmesg, the driver was registered, but it doesn't look like any devices was associated with the driver:

$ dmesg | grep irc
[   10.631162] lirc_dev: IR Remote Control driver registered, major 249 

So far, I've seen a number of forum pages suggesting that I use some trick to create a link between /dev/lirc and some other device that is the REAL IR sensor, like /dev/event5, but those cases assume that the real device is shown from /proc/bus/input/devices, and I don't see any such device there.

Any suggestions on how to fix or further diagnose this?

FWIW, it seems like this question describes a similar problem, but has no solution yet:

lirc isn't running because you are trying to start it as a regular user instead of root. That is why there are no lirc devices. irw needs to be run after lirc has been started, you will only get irw to show responses from the remote if lirc has been successfully started.

You need to start lirc as root, e.g.

sudo lircd start

Though I always use

sudo service lirc start
