Synology DSM 7 does not support external USB devices and their drivers. USB devices (Wi-Fi dongle, Bluetooth dongle, 3G/4G dongle, USB DAC/speaker, and DTV dongle) are no longer supported in DSM 7.0. If your Synology NAS is currently connected via a wireless dongle, it will be disconnected after the update. Many of you have asked me to create a simple guide to solve the problem with Home Assistant and USB CC2531 Dongle Zigbee Support. If all the steps below are performed successfully, everything will work fine. In this step by step guide I will show you how to add USB Support on DSM 7.

• STEP 1

Please Support My work by Making a Donation.

• STEP 2

Go to Control Panel / Task Scheduler / Create / Scheduled Task / User-defined script. Follow the instructions in the image below.

• STEP 3

Once you click on User-defined script, a new window will open. Follow the instructions below:

1. General: In the Task field type in DSM 7 USB Support. Uncheck the “Enabled” option. Select root User.
2. Schedule: Select Run on the following date then select “Do not repeat“.
3. Task Settings: Check “Send run details by email“, add your email then copy paste the code below in the Run command area. After that click OK.

chmod 777 /dev/ttyUSB0
chmod 777 /dev/ttyACM0
/sbin/modprobe usbserial
/sbin/modprobe ftdi_sio
/sbin/modprobe cdc-acm

• STEP 4

After you click OK on STEP 3 a new warning pop up window will open. Click OK.

• STEP 5

After you click OK on STEP 4 select your “DSM 7 USB Support” Task then click the “Run” tab. You will be asked to run DSM 7 USB Support – click Yes. Follow the instructions in the image below.

• STEP 6

Remove your USB stick/key and insert it back in.

Supported USB Keys / Devices

CC2531 Dongle Zigbee Supported on DSM 7.
CC2652RB Supported on DSM 7.
Wireless USB ASUS NANO N10 Supported on DSM 7.
ConBee II Zigbee Supported on DSM 7.
Z-Wave Stick Supported on DSM 7.
3D Printers Supported on DSM 7.

Note: If the script above don’t work for you can try to force the installation of the USB drivers directly into the kernel. Select your CPU model then download the files by following the instruction in the readme file.
Note: Contact me if you find a Supported USB stick and the guide works for you so I can add your USB stick model in the Supported USB stick/key list above.
Note: If you restart your NAS for one reason or another, remember to follow STEP 5 and STEP 6 again. If you don’t do that, you will lose the connection with your USB key.
Note: You can also add Triggered Task instead of Scheduled Task on STEP 2, then add a Boot-up rule. I don’t recommend it because you don’t know how DSM 7 will evolve in the future and how this might affect your NAS.
