Default Rapoo E6700 Bluetooth Keyboard z/y and other key problems

Hello guys, i have bought a Rapoo E6700 Bluetooth Keyboard and the manufacturer says its compitable with windows, abdroid and apple. i am german and running mz sgs3 with cyanogenmod 10.2 stable. i have connected my keyboard with android and set up german as key layout. but the keys are still not right:

ae and oe are not working and showing:
. and , are working but with shift they are displaying=

and many more. is it a cyanogenmod related problem or another ?

i have tried modified .kl and .kcm files in system/usr/keylayout and keychars.
it changes nothing.

the keyboard offers menue, home, play stop and volume keys. they are all working.

does someone knows a fix for this ? it reallz bugs me.
