Error Handling

If you get a message like "operation not permitted" you have probably not the right to open the USB device. Therefore, add an udev rule with:

sudo echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="06c2", MODE="0666", GROUP="dialout"' >>  /etc/udev/rules.d/10-persistent-usb.rules && sudo chmod a+r /etc/udev/rules.d/10-persistent-usb.rules && sudo udevadm control --reload-rules 

Make sure your user is in the group "dialout" with groups.
