Hi mlen, thanks for your help ! :) The interesting thing is: I have a pololu avr programmer (v20, an ISP-programmer it is), which uses also /dev/ttyACM<n>...and that one works fine. I plugged it in simultanously to ensure all drivers get loaded...and then I plugged in the Digispark...and udec does nothing. Or do I misinterpret here something? Cheers Meino
