Hello Uwe, This is the output of: ~$ ls -l /dev/ttyACM0 crw-rw---- 1 root dialout 166, 0 15 feb 17.03 /dev/ttyACM0 Then I changed the permissions of / dev/ttyACM0 like you said and everything works beautifully, thanks! You can automatically change the permissions of / dev/ttyACM0 during installation? so as to avoid the manual setting Kindly, Davide Governale.
