A big sorry from my side ... i totally forgot that i did also boot into Windows during the last months at least once ... looks like windows update or something similar broke the device, installing updates in that other system and rebooting to ubuntu did the trick. I had to reenable the profiles again in order to get it fully working but now it runs smooth as before :) - only tested the front port though :)
