It doesn't work on Ubuntu 16.04

[bigbigpark]

I'm using Xsens MTi-30 AHRS.
I downloaded xsens driver from ethzasl_xsens_driver
when I type the command,

$ roslaunch xsens_driver xsens_driver.launch

An error occured, the log messages are below:

$ roslaunch xsens_driver xsens_driver.launch

What should I do?

Best regards.

Try to set the driver to verbose mode (you can force it for example on this line: https://github.com/ethz-asl/ethzasl_xsens_driver/blob/f9bf1c9f02c266c04880d01a8e8be949507e94f3/nodes/mtdevice.py#L26 ). Post the output.

@bigbigpark Hi, have you solved this problem? I also met this question. How did you do？

[bigbigpark]

Pretty far, I cannot remember what I did.

I could not find any solutions on Ubuntu 16.04. So I upgraded my system on Ubuntu 18.04
