Maybe udev has assigned another device name to your Create cable (/dev/ttyUSB1, /dev/ttyUSB2...)?

Here are some commands that might help you identify the correct device name:

ls /dev/ttyUSB*
dmesg | grep ttyUSB


Once you find the correct device name you should update your turtelbot configuration.

If neither of the above commands produces results, then there might be something wrong with your cable.

Good luck!
