Ignoring infrared devices as input devices

[Martin Pitt]

Hello all,

We got a rather curious bug report in Ubuntu: https://launchpad.net/bug/322483

The problem is that some common infrared devices are detected as input
devices in the modern -evdev world, and thus end up being handled as
such:

udi = '/org/freedesktop/Hal/devices/temp/77'
  info.parent = '/org/freedesktop/Hal/devices/pci_14f1_8800'  (string)
  info.subsystem = 'input'  (string)
  input.device = '/dev/input/event6'  (string)
  input.originating_device = '/org/freedesktop/Hal/devices/pci_14f1_8800'  (string)
  input.product = 'cx88 IR (Leadtek Winfast 2000XP'  (string)
  linux.device_file = '/dev/input/event6'  (string)
  linux.hotplug_type = 2  (0x2)  (int)
  linux.subsystem = 'input'  (string)
  linux.sysfs_path = '/sys/devices/pci0000:00/0000:00:1e.0/0000:06:01.0/input/input6/event6'  (string)

However, with -evdev you can only use the digit and Enter keys. Thus
the bug reporter proposed to set rules like

     <match key="info.product" contains_ncase="saa7134 ir">
        <merge key="info.ignore" type="bool">true</merge>
     </match>
     <match key="info.product" contains_ncase="IR-Receiver">
        <merge key="info.ignore" type="bool">true</merge>
     </match>
     <match key="info.product" contains_ncase="cx88 IR">
        <merge key="info.ignore" type="bool">true</merge>
     </match>
     <match key="info.product" contains_ncase="bttv IR">
        <merge key="info.ignore" type="bool">true</merge>
     </match>

to ignore these devices as input devices. This will allow LIRC to use
them properly.

Now, I haven't encountered this kind of quirk so far, and I'm not sure
what its home should be. 

 - hal-info -> has lots of hw specific quirks, also for input devices,
   but doesn't have this kind of quirk so far
 
 - hal itself -> already ships rules to set input.x11_driver="evdev"
   for devices with input.keys capabilities, so it would be kind of
   "you broke it, you fix it"

 - lirc packages -> would be correct in the sense that if you don't
   have lirc installed, you can still use the devices in a restricted
   manner

Right now I'm leaning towards stuffing them into lirc.

Any opinions on this?

Thanks,

Martin
