How to remap the USB serial port name Maybe you should change the usb device port mode with the authority of read and write, more than make the port remap to an fixed name. install USB port remap: ./scripts/create_udev_rules.sh

chaeck the remap use command: ls -l /dev | grep ttyUSB usb_port_remap

Once you have change the USB port remap, you can change the launch file about the serial_port value.

I SOLVED MY PROBLEM WİTH COMANDS THAT ABOVE.

KERNEL=="ttyUSB*", ATTRS{idVendor}=="10c4", ATTRS{idProduct}=="ea60", MODE:="0777", SYMLINK+="rplidar"
