Z-Stick GEN 5 Controller is offline

OH 2.5.6
Docker Syno
Hello all,
last week after syno reboot, my stick gen5 stay offline :

changed from INITIALIZING to OFFLINE (BRIDGE_OFFLINE): Controller is offline

Dmesg shows this when i plug the stick :

[761423.060279] usb 1-3: new full-speed USB device number 4 using xhci_hcd
[761423.201829] Got empty serial number. Generate serial number from product.
[761423.697552] PPP generic driver version 2.4.2
[761423.714506] cdc_acm 1-3:1.0: ttyACM0: USB ACM device
[761423.720460] usbcore: registered new interface driver cdc_acm
[761423.727037] cdc_acm: USB Abstract Control Model driver for USB modems and ISDN adapters

In Dockerfile :

  USER_ID: "1026"
  EXTRA_JAVA_OPTS: "-Duser.timezone=Europe/Paris -Dgnu.io.rxtx.SerialPorts=/dev/ttyACM0"
  LC_ALL: "fr_FR.UTF-8"
  LANG: "fr_FR.UTF-8"
  - "/dev/ttyACM0:/dev/ttyACM0"

I’ve tried everything (reboot syno, change usb…) no luck.
I have downgraded on 2.5.5, same problem.

On my laptop WIN10, the stick works and i can read my network.

Any ideas ?

Ok i have found it !
By default, the rights on /dev/ttyACM0 is
crw------- 1 root root 166, 0 Jul 17 10:48 /dev/ttyACM0
I have changed for
crw-rw-rw- 1 root root 166, 0 Jul 17 10:48 /dev/ttyACM0

Zwave comes alive !

Does that survive a reboot?

Nop :frowning:
Same if you unplug/plug the stick…

So that is a Synology issue then.
Sorry. I had to ask. Better to find out now then later, unexpectedly.

Is it possible to define udev rules on that box ?
In case that is possible you can set an instruction to define permissions.
Just one example: https://askubuntu.com/questions/15570/configure-udev-to-change-permissions-on-usb-hid-device
