I also havent found it yet somewhere on the net. Neither did i find the other one, which doesnt even have a company sticker or something. Maybe its some diy device. Anyway, there is an option to switch the function of the Out ports, but i already tried it. Guess i just stick to the keyboard for now and be happy that its working at all
