Sonoff Zigbee 3.0 USB Dongle Plus wierdness

Not quite. It is indeed an issue with the dongle itself reporting incorrectly, but if you got shipped an early version of the dongle then the fix should be to write the new custom description of its CP2102 firmware for the USB-to-Serial Bridge chip, (and not just a simple firmware upgrade of the dongl CC2652P chip).

So while new Home Assistant 2022.2 release note mention USB discover of Sonoff Zigbee Dongle Plus, adding automatic USB auto-discovery in ZHA if USB dongle has unique custom product description…

…, this only applies to newer batches of shipped dongles as initial batches are missing ID in CP2102N.

ITead have posted a script/program that should let users themselves update the product description on already shipped dongles to supposedly match the 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).

So sad that ITead did not release a script tool based on this open-source cp210x-program by VCTLabs:

FYI, there is more information about how the automatic USB discovery feature works discussed here:
