My program needs to access ttyUSB without root permission.
I tried changing it with chmod 777 /dev/ttyUSB0 as you know, when I reboot this permission changed to default. How can I configure my udev rules.d for this?
Look for
ttyUSB*in therules.ddirectory and update it to look lke below:Leave any other entries you find on the line unchanged, add the mode attribute if it does not exist.
