[mythtv-users] iMON IR config on Fedora 14 is broken

[Todd Brunhoff]

  For some time now, my iMON mini has not worked under Fedora 13, and 
after upgrading to Fedora 14, that does not appear to work either. 
Various postings (e.g. http://wilsonet.com/?page_id=95) point to the 
change in design to the devinput driver and the move from the lirc_imon 
to the imon driver. I don't have a complete solution yet, but I have 
collected a number of notes along the way. Some of the notes may be 
helpful to others, and perhaps one of the notes points to my mistake and 
the reason I can't get the imon to work.

    * My primary symptom I am stuck on is that 'irw' produces no output
      even though I can see the IR device winking when I press buttons
      on the remote. I don't see an errors in /var/log/messages and
      lircd is running and reports that it is using the device I
      configured in the next bullet.
    * The preferred setup for the lircd is to specify the devinput
      device by-id explicitly. For me, the devices that appear are
      /dev/input/by-id/usb-15c2_0042-event-if00
      /dev/input/by-id/usb-15c2_0042-event-mouse
      /dev/input/by-id/usb-15c2_0042-mouse
      I cannot find any reference to which one of these devices is the
      correct one to use. Lircd can attach to the first two but not the
      last one.
    * This posting
      (http://mythtv.org/pipermail/mythtv-users/2010-November/301836.html)
      suggests that ir-keytable could be used to load scancode->keycode
      mappings to the driver. ir-keytable is part of v4l-utils, but none
      of my yum repositories carry that package.   I found some binary
      RPMs for v4l-utils, but they exclude ir-keytable binary. I found
      source for 0.8.0 and 0.8.1 at
      http://linuxtv.org/downloads/v4l-utils/ and I found a test tarball
      for 0.8.2 (http://people.fedoraproject.org/~jwrdegoede/). This
      does not seem quite ready for prime time.
    * The packages above build and include keymap tables for the imon
      (utils/keytable/rc_keymaps/imon_pad and
      utils/keytable/rc_keymaps/imon_mce). However, using the command
      'ir-keytable -w <file>' to load either of these files does not
      work. The imon_pad file loads without complaint, but 'ir-keytable
      -r' shows no keymappings. Loading the imon_mce file produces one
      error for every line that looks like 'Setting scancode <X> with
      <Y> via EVIOCSKEYCODE: Invalid argument'.
    * With the old lirc_imon driver, you could select whether it decoded
      MCE or native iMON codes by including a param when loading the
      driver with insmod or modprobe: protocol=1 or protocol=0. This is
      now set by a parameter in the keymap files, or with 'ir-keytable
      -p <protocol>' where protocol for the iMON is RC-6 to decode MCE
      codes, and empty (?) to decode native iMON codes.

This all makes me think that the imon driver 
(/lib/modules/2.6.35.10-74.fc14.x86_64/kernel/drivers/media/rc/imon.ko) 
is not fully baked and that I'll have to wait for Fedora 15. Please tell 
me I am wrong...
