The actual LIRC devices (/dev/lircd and /dev/lirc0 if using Fedora)
are still not present. What type of IR receiver are you using? You
likely need to load the LIRC driver (either lirc_i2c for Hauppauge
cards or lirc_serial for serial IR receivers).

Looks good. Should create /dev/lirc symlink to /dev/lirc0 when the
correct LIRC module is loaded.

What's the output of

# lsmod |grep "lirc"

after you've loaded the correct LIRC module? You generally modprobe
the specific LIRC driver for your receiver which in turn pulls in
lirc_dev automatically.
