i switched to evdev and the perixx game-mouse with seven buttons (http://www.perixx.com) now works absolutely fine. however, my old perixx keyboard didn't work with evdev at all. it has a very slim layout with all keys present just once. the evdev driver triggered the alt key non-stop, so that, if i typed something, menues and dialogs popped up randomly. the keyboard was not to mention so or so. i now have a cherry evolution stream, which seems to be very good. however. with evdev, the arrow keys, the window keys, and the multimedia keys are dead. the arrow keys on the numpad work. also, evdev doesn't recognize the german keyboard layout by itself (why is 'us' default? the default should be none or locale!) here's the xorg and the proc output:
