On linux, node red server access a tty device for no reason

Hi,

my installed node red server interfere with a /dev/ttyUSB0 device and I dont want that
how can I tell nodered server to leave that device alone ?

it is a freshly plugged device and I never configured into nodered

thanks

I'm what way is it interfering with it?

If you search for USB in the editor does it find anything?

Show us the full node red startup log please.

well I use a software on that usb device, and every once in a while that device has a handle from nodered

I want to stop that
I just installed node red, did not do anything around it
the only workaround is to disable the server

why is nodered accessing my usb device ? it is a usb lidar, I dont see why nodered would , by default access it

Do you have any flows added to the workspace?

Did you search (ctrl-f) for usb inside the node-red editor?

Did you install any contrib nodes? (What does palette manager show?)

I don't understand what you mean by that.

Also please show us the node red startup log.
