I'm trying to configure lirc with a RC-6 receiver. So far I've got the system to be able to read inputs from /dev/input/event0 and I've recorded the remote keys with irrecord, but irw doesn't seem to show any output. This is my actual configuration:

Kernel configuration:
Code:
Device Drivers  --->
    <*> Multimedia support  --->
        [*] Remote Controller support
        <*> Compile Remote Controller keymay modules
        [*] Remote controller decoders  --->
            <*> LIRC interface driver
            < >   Enable IR to LIRC bridge
            <M> Enable IR raw decoder for the RC6 protocol
        [*] Remote Controller devices  --->
            <*> Windows Media Center Ed. eHome Infrared Transceiver


/etc/portage/make.conf lirc device:
Code:

# LIRC
LIRC_DEVICES="devinput"


/etc/conf.d/lircd options (the rest are commented)
Code:

LIRCD_OPTS="-H devinput -d /dev/input/by-id/usb-_Windows_Media_Center_IR_Transceiver_GFKE-event-if00"
LIRCD_SET_SYSCLASSRCS="rc0"


With the above configuration, ir-keytable outputs the following:
Code:
Found /sys/class/rc/rc0/ (/dev/input/event0) with:
        Driver mceusb, table rc-rc6-mce
        Supported protocols: RC-6
        Enabled protocols: RC-6
        Repeat delay = 500 ms, repeat period = 125 ms

And I can use irrecord to record all the keys in my remote. If I run irw and press some keys, irw doesn't seem to do anything, but dmegs outputs the keypresses
Code:
[ 3671.828922] mceusb 3-2:1.0: rx data: 81 7f (length=2)
[ 3671.828933] mceusb 3-2:1.0: Raw IR data, 1 pulse/space samples
[ 3671.828941] mceusb 3-2:1.0: Storing space with duration 6350000
[ 3671.828953] mceusb 3-2:1.0: rx data: 9f 14 01 (length=3)
[ 3671.828961] mceusb 3-2:1.0: Got long-range receive sensor in use
[ 3671.828970] mceusb 3-2:1.0: rx data: 9f 15 00 00 (length=4)
[ 3671.828979] mceusb 3-2:1.0: rx data: 80 (length=1)
[ 3671.828985] mceusb 3-2:1.0: End of raw IR data
[ 3671.829001] mceusb 3-2:1.0: processed IR data, calling ir_raw_event_handle


I've also tried compiling the kernel with 'Enable IR to LIRC bridge', but doing so, I can't get any output while doing a cat to /dev/input/event0 nor irw works. Any idea why the kernel sees the remote input but lirc doesn't seem to like it (despite recording the keys without issue)?

I went thru that ordeal half a year ago when my non-LIRC remote disappeared (I have two little dogs) and I happened to have a media center remote as a spare.
After testing different configurations I ended up with working setup.
My final kernel config is not exactly same. Differences are below.
Code:
<M> Compile Remote Controller keymap modules
< > LIRC interface driver
<*> Enable IR raw decoder for the RC6 protocol
<M> Windows Media Center Ed. eHome Infrared Transceiver

I found it was important in what order they load, this is why some are built as modules. Enabling LIRC interface driver messed it up for me.
Code:
LIRC_DEVICES="userspace"

I remember /etc/lirc/lircd.conf plays important role, but cannot recall how I generated it. :(

Edit: I think I copied it over from /usr/share/lirc/remotes/devinput/lircd.conf.devinput.

Just with that changes doesn't seem to work either. Whats your /etc/conf.d/lircd config?
