I am trying to connect an imu VN-100 Rugged to ROS via this package. But, I get the following output in my terminal:

process[rosout-1]: started with pid [13597]

[imu-2] process has finished cleanly

I tried to change the baud rate of /dev/ttyUSB0 to something else according to the acceptable baud rates in this link. However, I get the same result each time.

Does anyone know how I can solve this problem.

Thank you.

link text This is what solved it for me. Now this is a setting you can change in the launch file itself.

The reset function in the SDK of the imu did not let me open the port. The problem is solved now.

How did you solve the issue?

Could you tell me how you solve this problem, please? Do I need to install any SDK before I install the ROS driver?
