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:
