Community help wanted to whitelist all compatible Zigbee and Z-Wave dongles/adapters for automatic USB Discovery in Home Assistant

Hello, I was just wondering if anyone has experienced this issue before, Is set it up originally and it was all working correctly. Then I tried installing ZIgbee2MQTT and it failed, I have deleted Zigbee2MQTT and tried going back to ZHA but it keeps failing, I get the error Failed to set up check the logs

I have tried to uninstall it Remove the Zigbee database file, Go To a backup of home assistant before I installed Zigbee2Mqtt.

When I reinstall ZHA it finds the serial device path to the USB without any Issues,

Created configuration for CP2102N USB to UART Bridge Controller, s/n: Serial Number shows up - Silicon Labs.

But I get this error image

Any Ideas What I am doing wrong?

You are sure Zigbee2MQTT is not running anymore ?

Yes It’s definitely not running or installed

@Luke1 off-topic for this subject so please suggest that you create a brand new thread for that instead.

FYI, got a reply from ITead that they will change default “CP2102 USB to UART Bridge Controller” text in the Product Description String value field to “Sonoff Zigbee 3.0 USB Dongle Plus” in their next batch.

They already tested that USB discovery works in Home Assistant on Linux, but the change will require them to generate and provide a custom device driver for Microsoft Windows-based operating systems.

Why it would require them to generate and provide a custom device driver I do not know as changing only changing the “Product Description” and leaving the original VID and PID should not require that.

BitronVideo AV2010/10 ZHA stick to be added here:

ZigStar Stick USB discovery to be added here (PR patch by @mercenaruss = the maker of ZigStar):

ZigStar is by the way an open source hardware (USB dongle is based on CC2652P + CH340B chip):

@tteck reported in another thread that the very latest batch of Sonoff Zigbee 3.0 USB Dongle Plus that has shipped now looks to have a unique product description value written to CP2102N EEPROM.

The question that remains to answer is which exact product description that ITead chose to go with.

Perhaps people with new batch can verify product description and test changes from this pull request:

That uses wildcards so think it will work as long as product description contains “sonoff” somewhere(?).

@tteck posted serial path old and new batch shipped from ITead with updated Sonoff Zigbee 3.0 USB Dongle Plus product description in

Old ID


New ID


Serial path adds “usb-” + vendor as prefix and some ID and port-number as suffix + added underscores.

So assume new product description is “Sonoff Zigbee 3.0 USB Dongle Plus” (without underscores).

Again, can someone with new batch HW test PR? →

I do not own a dongle from the new batch with the new product description so can not test it myself.

FYI, ITead now posted a script/program that should let users themselves update the product description on already shipped dongles to supposedly match description already written to latest batch of dongles:

Tested it myself on a Windows 10 computer and it did not work for me (it closed without any messages).

Sadly ITead did not just release a script tool based on this open-source cp210x-program by VCTLabs:

Again, the point of having a unique custom product description is to allow USB auto-discovery in ZHA:

FYI, OpenMyDog submitted a new PR for ZHA discovery of Sonoff Zigbee 3.0 USB Dongle Plus:

FYI, Home Assistant 2022.2 release notes now menation USB discover of Sonoff Zigbee Dongle Plus:

Again, this only applies to newer batches of shipped dongles the initial batches missing ID in CP2102N, as if your dongle does not have this unique description then it will be discovered as dongle for Z-Wave.

FYI, looks like Home Assistant will soon support automatic USB discovery for the new ITead’s “Sonoff Zigbee 3.0 USB Dongle Plus V2” model “ZBDongle-E” based on Silicon Labs EFR32MG21 if merge:

      "vid": "1A86",
      "pid": "55D4",
      "description": "*sonoff*plus*",
      "known_devices": ["sonoff zigbee dongle plus v2"]

It uses a WCH CH9102F (CH9102/CH340 device drivers) for USB-to-UART chip which has VID (Vendor ID) "1A86 "and PID (Product ID) 55D4 as well as the new USB product description identifier “sonoff zigbee dongle plus v2” on this variant.

see product discussion:

FYI, it is still a known problem that USB discovery entries for Z-Wave JS are too generic, with the main root cause of that problem being most manufacturers of Z-Wave Controller, unfortunately, have the bad habit of not writing their own custom “Description” to USB-to-Serial converter/bridge chip EEPROM.

See issue →

The Z-Wave discovery of these USB devices was removed months ago, in release 2022.9. It would seem the issue has been addressed, or do you observe otherwise?

FYI, Zvidar released both a black-colored Z-Wave 800 series USB dongle called “Zvidar Z-GW-V20” as well as a white-coloured Silicon Labs EFR32MG21 based Zigbee dongle called “Zvidar Z-DG-Z01”:

Apparently, the “Zvidar Z-DG-Z01” USB Zigbee adapter is USB discovered by VID/PID "1a86:55d4 " and product identifier "QinHeng Electronics USB Single Serial " or with serial by-id as "usb11a86_USB_Single_Serial_54F7005713-if00 " (where “54F7005713” is the serial number), which I believe is just a default for WCH CH340 Serial-to-USB bridge chip and not a unique product identifier, or is it?

Again, someone should try to inform companies like Zvidar that they really need to use Serial-to-USB bridge chip with writable EEPROM and write a unique USB product identifier to it for USB discovery!

Check out this blog:



First, Zvidar are focused on the ODM market, this is primarily meant to be a whitelabel product.

Most variants of the CH340 dont include an EEPROM, only the CH340B has one AFAIK.

Anyone got the Aeotec Zi-Stick (model “ZGA008”) and if so can check its USB product description?

If anyone own one would appreciate it if let us know USB product description to be used as identifier:

FYI, there is a draft pull release for ConBee III USB product description for automatic USB discovery under Home Assistant OS (e.i. ZHA whitelisting for automatic USB discovery of ConBee 3 adapter):

Tip to radio USB adapter manufacturers using CP2102 or CP2102N CP210x USB-to-serial bridge chip is to check out this new CP2102N programmer add-on for Home Assistant that allow end-users to program the manufacturer and product strings to the EEPROM CP210x USB-to-serial converter chip if missed doing so for an already shipped batch of adapters or for want to change a string (or both):
