maybe out of date, it's group 'dialout' on my systems. debian 9.1 stretch

bearing in mind he hasn't got root, how do you edit /etc/udev/rules.d/45-maple.rules ?
can you try without sudo/root

Code: Select all

ls -l /etc/udev/rules.d/45-maple.rules
ls -ld /etc/udev/rules.d
ls -ld /etc/udev

Basically if he cant access the USB Serial, he is never going to be able to talk to the hardware.

He may not even be able to upload to a Arduino Uno.


There is nothing we can do on systems which are locked down in ways the user cant change.
