24 Hi mlen,
25
26 thanks for your help ! :)
27
28 The interesting thing is: I have a pololu avr programmer (v20, an
29 ISP-programmer it is), which uses also /dev/ttyACM<n>...and that
30 one works fine. I plugged it in simultanously to ensure all drivers
31 get loaded...and then I plugged in the Digispark...and udec does
32 nothing.
33
34 Or do I misinterpret here something?
35
36 Cheers
