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?
