[SOLVED] How to disable IR remote as keyboard?

I have got my IR remote to work with LIRC, but it seems that IR usb dongle is recognized also as a keyboard, and duplicates arrow presses.

For example irw gives following output:

000000037ff07be9 00 Play mceusb
000000037ff07be0 00 Down mceusb
^[[B000000037ff07be0 01 Down mceusb
^[[B000000037ff07be0 02 Down mceusb
^[[B

Archlinux LIRC Wiki has a section "Setup a HID device with lirc" which teaches how to use IR device which is recognized as a keyboard, but my device already works as IR remote and i do not need this duplicating behavior.

Is it somehow possible to block my usb device as HID keyboard without damaging the IR remote functionality?

Some info about my device, if it helps:

cat /proc/bus/input/devices

gives

...
I: Bus=0000 Vendor=0000 Product=0000 Version=0000
N: Name="Media Center Ed. eHome Infrared Remote Transceiver (1934:0702)"

Re: [SOLVED] How to disable IR remote as keyboard?

Found the solution.
To block the unneeded keyboard functionality i added following snippet to file /etc/X11/xorg.conf.d/10-quirks.conf

Section "InputClass"
        Identifier "Ignore IR remote as keyboard"
        MatchProduct "Media Center Ed. eHome Infrared Remote Transceiver"
        Option "Ignore" "on"
EndSection

There Identifier is just a descriptive name which i choosed myself and MachProduct is found from the output of the command

cat /proc/bus/input/devices

Now my IR remote works and doesn't give me duplicating keyboard events.
Life is good!
