Hello,

I downloaded the package. When I run:
roslaunch imu_vn_100 vn_100_cont.launch
I get the following result in the terminal. "/imu: VN: Permission denied". Would you please help me to solve the problem.

Thank you.

Update: I tried to change the baud rate both on the launch file and the USB port, but it didn't change the error at all.

On line 217 in src/imu_vn_100.cpp, try changing BINARY_ASYNC_MODE_SERIAL_2 to BINARY_ASYNC_MODE_SERIAL_1 and see if that changes anything. I had the same error and this fixed it for me.
