Synology DSM 7.2 - Adding USB Devices / Dongles (SkyConnect / Z-Wave)

DSM7.2-USB-DRIVER.md

Adding SkyConnect Dongle according to Blog Post or better Youtube

Summary

Synology has disabled USB drivers. Additionally one important driver is not available on Synology DSM 7+. Thus we need to enable some USB drivers plus download one driver and enable this on the system. For future DSM updates we need to add a Scheduled Task, so that the drivers will be loaded.

This Tutorial works fine for DS920+, in case your NAS has another process, change "geminilake" within the commands to your processors architecture name according to https://kb.synology.com/en-global/DSM/tutorial/What_kind_of_CPU_does_my_NAS_have!

Download usb drivers from Github

git clone https://github.com/robertklep/dsm7-usb-serial-drivers.git ~/DSM-USB-DRIVER/

Review available USB Devices

ls /dev/ttyU*

Copy necessary driver to lib/modules

sudo cp ~/DSM-USB-DRIVER/dsm7-usb-serial-drivers/modules/geminilake/dsm-7.2/cp210x.ko /lib/modules

Adjust access rights of new ko module

sudo chmod 644 /lib/modules/cp210x.ko

Initiate usb-serial-drivers.sh

sudo chmod +x ~/DSM-USB-DRIVER/dsm7-usb-serial-drivers/usb-serial-drivers.sh
sudo sh ~/DSM-USB-DRIVER/dsm7-usb-serial-drivers/usb-serial-drivers.sh start

sudo sh /usr/local/etc/rc.d/usb-serial-drivers.sh start

Check all devices connected to NAS

ls /dev/ttyU*

Add following startup script to NAS through Task Manager

cp ~/DSM-USB-DRIVER/dsm7-usb-serial-drivers/modules/geminilake/dsm-7.2/cp210x.ko /lib/modules
bash ~/DSM-USB-DRIVER/dsm7-usb-serial-drivers/usb-serial-drivers.sh start

For anyone having issues here, remove "/dsm7-usb-serial-drivers" from the commands

I will add that if you use HA in Container manager you will need to run the container with "High privilege" (in Capabilities) section of container configuration.

BEWARE it is considered as UNSAFE as the container can have access to Syno Filesystem.

Another solution is to launch the container via docker compose and pass the device (customize to your needs):

version: "2"
services:
  homeassistant:
    image: homeassistant/home-assistant:stable
    container_name: homeassistant
    network_mode: host
    restart: always
    volumes:
      - /volume1/docker/homeassistant/config:/config
    devices:
      - /dev/ttyUSB0
    environment:
      - TZ=Europe/Madrid

You should be able to use docker-compose file in Container Manager via "Project" (untested)

The script on the Task Manager isn't working, the output is:
sudo: a terminal is required to read the password; either use the -S option to read from standard input or configure an askpass helper
sudo: a password is required

At every NAS restart I have to run all commands again

Did you select root as task executer?

Did you select root as task executer?

Thanks, it works now.
I switched to root and I had to change the script, since the files are located inside a user folder.
It had to be something like:

sudo cp /var/services/homes/USER/Downloads/DSM-USB-DRIVER/modules/geminilake/dsm-7.2/cp210x.ko /lib/modules
bash /var/services/homes/USER/Downloads/DSM-USB-DRIVER/usb-serial-drivers.sh start

When I run sudo sh /usr/local/etc/rc.d/usb-serial-drivers.sh start, I get:

sh: /usr/local/etc/rc.d/usb-serial-drivers.sh: No such file or directory

When I run sudo sh /usr/local/etc/rc.d/usb-serial-drivers.sh start, I get:

sh: /usr/local/etc/rc.d/usb-serial-drivers.sh: No such file or directory

What is the output of:

sudo ls -la /usr/local/etc/rc.d/ | grep "usb"
