USB device path on Synology

Hello.
I am trying to install HA in docker to my Synology NAS. The problem is in the PATH_TO YOU_USB_STICK. in the command:
sudo docker run --restart always -d --name homeassistant -v /PATH_TO_YOUR_CONFIG:/config --device=/PATH_TO_YOUR_USB_STICK -e TZ=Australia/Melbourne --net=host ghcr.io/home-assistant/home-assistant:stable

As i have connected my Conbee II to the USB hab with UPS i can’t find the correct path to USB device.
When i’m using “lsusb” command i can see that Conbee II is connected.
Is there a way to determine the correct path to my USB stick.

You can SSH into your Synology with your admin user, and do ls -la /dev/tty*.

That’s what I did in the past on DSM 6.2

There too much devices:

Oh that doesn’t look right. :sob:
I used to have ttyUSB0

Sorry turns out I got nothing. I recall having to install some drivers from synokernel, have you perhaps done that?

Thanks for the link. But unfortuanally it does’nt work on my system. I installed drivers, but USB device is not detected.
