Synology: How to Add USB Support on DSM 7

Synology How to Add USB Support on DSM 7

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.

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.

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.
