I've got Debian 10 as OS and for a Project, I need my arduino to always be connected as /dev/ttyUSB0, not any other ttyUSB-number, and I need it to be connected with the 0777 rights for a script to work.
I've read some things about udev, but nothing I tried yet worked.
I tried creating
with the content
SUBSYSTEM=="tty", MODE="0777", KERNELS=="ttyUSB0"
but it does not work, even after reboot (like nothing changed). I must admit though that I do not really understand udev.
How to do this?
