Title:
  imon driver (or IT87 driver) does not work, irw crashes lircd

Status in “lirc” package in Ubuntu:
  New

Bug description:
  Binary package hint: lirc

  Description:    Ubuntu 8.10
  Release:        8.10
  lirc 0.8.3-0ubuntu2 Linux Infra-red Remote Control support

  oot@mediapc:~# dmesg | grep imon

  When I run irw it simply exits the 1st time without any message, the
  second time it errors and the lirc daemon crashes.

  root@mediapc:~# /etc/init.d/lirc restart
  * Stopping remote control daemon(s): LIRC [ OK ]

  I do not have a /dev/lirc0 but I do have /dev/lircd.
  Running irw /dev/lircd does not help.

  Mode 2 errors:

  root@mediapc:~# mode2
  mode2: error opening /dev/lirc
