I own Gigabyte U7000 DVB-T receiver with integrated remote IR
receiver. Receiver is working but I have problems with IR receiver.

Dmesg reports:

When I press key on remote:

[15089.153588] dib0700: Unknown remote controller key:  D 78  1  0

By the way, I use firmware version 1.1 because there are problems with
v. 1.2 (keys are simply not detected, even if I use

In source code of module dvb_usb_dib0700 I can see that my remote
control is not supported. Supported remotes have hardcoded key maping.

I could manually add keymap to driver, but I would like to do mapping
in userspace with LIRC. I have seen a lot of howto's telling me to use
proper /dev/input/event? socket but driver only sends resolved keys to
it. If remote controller key is not recognized I only get "Unknown
remote key.." line in kernel log, /dev/input/eventX stays silent.

What should I do to get key codes directly to /dev/input/eventX socket
without mapping them in dvb_usb_dib0700? Or is there any other way to
make remote controller work?

Thanks and best regards,
