Could not set BinaryResponseListener output on device

Hi guys, I got vectornav vn200, and I have followed exactly this tutorial : https://github.com/dawonn/vectornav When I write "roslaunch vectornav vn200.launch", I get an error:

quuser@quuser:~$ roslaunch vectornav vn200.launch

Before it was connected to /dev/ttyTHS0, I was getting error ls: cannot access /dev/ttyTHS0: No such file or directory, however i changed it to dev/ttyUSB0 and it is fine.
