[ERROR] []: start: open: Permission denied about bno055_usb_stick HOT 7 CLOSED

The easiest fix will be running the driver with sudo.

The next easiest method will be sudo chmod 666 /dev/ttyACM0.

The right thing to do is sudo usermod -aG dialout $USER

The other thing you can do is to set up a udev rule to create correct permission for /dev/ttyACM0

Agree with @BillWSY . What I always do is the third one. Doing once after installing Ubuntu is enough.

Hey,
thank you for your answers.

I tried typing sudo cmod 666 /dev/ttyACM0 and it worked. But I need to type it every time I plug in the usb imu stick.

Then I tried to create a rule by creating a rule file in /etc/udev/rules.d
and applied following rule in the created rule file:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0x152a", ATTRS{idProduct}=="0x80c1", MODE:="0666"

With this rule the imu stick worked once. Now when I run the node I get following output:
[ERROR] []: start: open: Device or resource busy

EDIT: In the case I plug out the imu stick and replug it in, I get this error. Is it possipble that I have to restart roscore in this case?

How can I solve this?

Thank you again :)

Your udev rule may miss a GROUP attribute. Or try the 3rd proposal in @BillWSY 's post.

I tried sudo usermod -aG dialout $USER but somehow it said, that permission was still denied.
Do I have to modify anything in this line?

sudo usermod -aG dialout $USER should work on ubuntu 16. Reboot the computer or google "ubuntu 16 add user to group dialout".

it works, thank you for your help!
