Hello,

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

By recommendation from the list linux-media I use the older firmware from http://palosaari.fi/linux/v4l-dvb/firmwa...40/4.0.11/

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

The TV part is working, however the IR receiver is not working yet.

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

Code:

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:

Code:

# 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:

Code:

# 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

I have a similar problem (different card, same chip, see this debian bug) since linux 4.5.

Does downgrading to 4.4 or 4.3 work for you?

No, I returned the card to the vendor, not been able to get any information from the IR port.
