Sonoff Zigbee 3.0 with HA OS

You do not need to install a device driver when using Home Assistant Operating System on barebone.

If using other OS/image then you might need to first install the right drivers and reboot before plug it in.

Sonoff ZBDongle-E needs CH9102/CH343 device drivers from WCH, while if you have Sonoff ZBDongle-P then it instead needs CP210x USB to UART Bridge VCP Drivers from Silicon Labs.

Read in another thread that someone has problems with their computer enclosure not allowing them to physically plug the USB adapter all the way in and as such USB connector didn’t make proper contact.

The workaround was to use a USB extension cable that has a longer USB port so properly plugged in.

Alternative was to modify the computer enclosure removing casing around the USB port to make it fit.
