[PROBLEM] RPI 2 + Harmony One

[bang_]

Hi,

i have ordered 2 new Rasperry Pi 2's and installed Xbian 1.0 with Kodi 14.2-BETA2 (compiled 25021015). At the beginning , the harmony one works fine and everything / every button was ok and accepted by the rpi2. But after a few updates (settings->xbian->updates), the "OK" Button doesn't work anymore. That's why, I have to reinstall the whole system .

I have tried a lot of solutions (like this). But nothing helps.

Has anyone an Idea for me?
