Works great with Raspberry Pi and OpenELEC

The configuration is totally easy. Download software flirc.tv and install (works fine on Win8.1 x64).
Flirc USB Stick connect, select Profile. Did the simple chosen which includes only the direction keys, Enter and Return, as these are just as available on my TV service and the TV will only respond to them when I am in the menu.

Then click on the "Go" button on the screen and the buttons blink to which you then have to press the desired button on the remote control.
If a signal has been correctly identified, the software jumps to the next key.

Then simply remove the stick and put it in the Raspi. Works instantly and flawlessly.

Total duration of the configuration was not even a minute in my case.
