This looks indeed weird. You have a Winbond 8769L  and tries to use the
lirc_wpc8769l kernel module, which should present data from your remote
on /dev/lirc0. However, this kernel module has been dropped, it never
made the transition process when the kernel modules was moved from lirc
to the kernel prior to 0.9.0.

Still, the kernel gives you some sort of input. The question then
becomes what module it uses for your device, and if it's supposed to
support that device. So,  what is the dmesg output when you plugin in
the usb receiver?

This is an old  bug. We need this input to advance it. Otherwise, it
will eventually be closed.

Title:
  Lirc-Drop-Outs / Lirc just stops receiving signals

Status in lirc package in Ubuntu:
  Incomplete

Bug description:
  Hi,
  After asking around in several forums I now file a bug-report here because nobody could actually help me.

  I'm using Mythbuntu (Ubuntu Precise 12.0.4.1 on 64Bit with always
  newest kernel) with xbmc on top and an intel CIR-receiver connected
  with a CIR-header on the mainboard for infrared. I'm sorry I just
  can't tell you the exact lirc-package-name because I'm using a
  different computer for writing this report, right now. It is the usual
  lirc-package provided with mythbuntu. If there were any updates in the
  last 4 months, I of course installed them.

  My problem is that Lirc spontaniously just stops receiving any input.
  I have to reboot the system afterwards to get it back to work again.
  The problem can occur a few seconds after boot-up or after a couple of
  hours - there seems to be no certain time for the drop-out.

  Restarting Lirc didn't work for a long time until I found out that
  /etc/lirc/hardware.conf has a line causing trouble:

  LOAD_MODULES="true"

  needs to be set to false because lirc is not using any kernel-modules
  in my mythbuntu-CIR-setup (the setup was done by mythbuntu
  automatically).

  When doing so, lirc can be restarted but without effect. IRW and xbmc
  both still don't see any input.

  Strange thing: When changing the load-modukes-line to "false" xbmc is
  reacting too quick after a reboot and receives fail-inputs. E.g. When
  pressing right-button on the remote it sometimes receives left or
  enter-pushes. Holding the button causes the menu rotating a lot too
  fast. Drop-Outs still occur.

  Therefore I changed the line back to "true". After a reboot, reaction-
  speed is usual again.

  I don't understand at all why lirc is starting-up properly on boot
  with the faulty line. I figured out that there are just no kernel-
  modules for my CIR. Lirc is recognizing it as "Winbond 8769L CIR port
  (e.g. Acer Aspire 6530G)"

  The drop-outs are really annoying. When not suffering them lirc is
  just running fine.

  
  Last forums I discussed the problem on many pages:

  -debian-und-derivate/117969-lirc-läuft-plötzlich-nicht-mehr/

  http://www.mythtvtalk.com/suffering-lirc-drop-outs-16275/


  My /etc/lirc/hardware.conf:

  ----------------------------------------------------------------------------------

  #to leave this set to "false"
  FORCE_NONINTERACTIVE_RECONFIGURATION="false"
  START_LIRCMD=""

  ----------------------------------------------------------------------------------

  Is it possible that there is some trouble with the modules lirc_dev
  and  lirc_wpc8769l?

  In the first forum someone told me lirc_wpc8769l doesn't actually exist.
  Somewhere else (I think it was a bug-report) someone wrote something about conflicts with 
  lirc_dev, some sources and udev...not sure.

  I would be glad for help / confirmations.
