I tried to open the ttyUSB0 console from the Terminal view of Intel Pathfinder but it shows:
Failed to open port /dev/ttyUSB0 with selected settings.
The error from the serial driver:
Error opening /dev/ttyUSB0: Permission denied
Can you suggest a fix?
Usaully this happens because your user is not part of the dialout group that controls the acces to serial ports.
Add your user to dialout group .
You can type:
sudo chmod 0666 /dev/ttyUSB0
then go back to Intel Pathfinder and open the ttyUSB0 console from the Terminal view
