Problems with cx23885 IR receiver

Problems with cx23885 IR receiver

[Florian Lindner]

Hello,

I bought a TechnoTrend TT-budget CT2-4500 [1,2] DVB-C card.

By recommendation from that list I use the firmware from
http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/4.0.11/

Aaccording to linuxtv.org my card is an OEM version of the DVB Sky T980C).

Thanks to this list, who helped me to get the TV part working. However,
the IR receiver is not working yet.

I do a modprobe ir-kbd-i2c, the journal then says:

kernel: Registered IR keymap rc-fusionhdtv-mce
kernel: input: i2c IR (FusionHDTV) as /devices/virtual/rc/rc0/input20
kernel: rc rc0: i2c IR (FusionHDTV) as /devices/virtual/rc/rc0
kernel: ir-kbd-i2c: i2c IR (FusionHDTV) detected at i2c-7/7-006b/ir0
[cx23885[0]]

The device works as a dev/input device:

# ir-keytable
Found /sys/class/rc/rc0/ (/dev/input/event17) with:
        Driver ir-kbd-i2c, table rc-fusionhdtv-mce
        Supported protocols: unknown
        Enabled protocols: unknown
        Name: i2c IR (FusionHDTV)
        bus: 24, vendor/product: 0000:0000, version: 0x0000
        Repeat delay = 500 ms, repeat period = 125 ms

However, I can get no results from event17 using `cat /dev/input/event17`.

The remote works (I can see the IR blinking using a cellphone camera)

Also, lircd gets no results:

# lircd --loglevel=debug --nodaemon -H dev/input -d /dev/input/event17
lircd-0.9.3a[2273]: Warning: Running as root
lircd-0.9.3a[2273]: Info: Using remote: Technotrend.
lircd-0.9.3a[2273]: Notice: lircd(devinput) ready, using /var/run/lirc/lircd

Now using irw /var/run/lirc/lircd also get's no signales from the remote.

Any hints you might have? Any more lowlevel debugging ideas?

Thanks,
Florian
