[pvrusb2] IR help linux newbie

Fri Dec 29 21:28:15 CST 2006

Ok,

So I made some changes, but I'm still not any closer to a solution
unfortunately.

I used the commands you suggested:
mknod /dev/lirc0 c 61 0
ln -s /dev/lirc0 /dev/lirc

And now I have this:
[root at schmitzerLNX dev]# ls -l /dev/lir*
lrwxrwxrwx 1 root root    10 Dec 29 22:06 /dev/lirc -> /dev/lirc0
crw-r--r-- 1 root root 61, 0 Dec 29 22:05 /dev/lirc0
srw-rw-rw- 1 root root     0 Dec 29 22:09 /dev/lircd

*I noticed I don't have lircm, could this be an issue?
Also before I ran mknod and ln -s, lircd was the only one listed.  Should
lirc already exist or does that just get created during the ln -s step?

Then I restarted the lircd service, and still no luck.  Here is the
messages:

Dec 29 22:09:26 schmitzerLNX lircd-0.8.1-CVS[3106]: lircd(userspace) ready
Dec 29 22:09:29 schmitzerLNX lircd-0.8.1-CVS[3106]: accepted new client on
/dev/lircd

device
Dec 29 22:09:29 schmitzerLNX lircd-0.8.1-CVS[3106]: caught signal

*Same errors as before, but now I do have lirc0 created via mknod

Also here is my lirc.rules file if that helps at all
KERNEL=="lirc[0-9]*",   NAME="lirc%n"
KERNEL=="lirc0",                SYMLINK="lirc"
