I have downloaded repository, compiled using catkin_make , and connected a cheap USB-UART module to check how it works. when i used command: $ rosrun serial serial_example -e|/dev/ttyUSB0 9600 TestString i got: bash: /dev/ttyUSB0: Permission denied I belong to dialout group, and don't know what else I can do.

(The same problem appears when i try to check this library on RaspberryPi with ROS.)
