    And this seemed to work for Windows 11. Weird that an old driver works better than the latest one.

    I have the PL-2303 TA chipset.

Thanks for the info, this solved a problem with a Windows 11 installation and a jewelry engraver.

There seems to be a new driver (v4.0) as of 12/30/21. Has anyone given it a go yet? I'm trying to get a handheld radio (AnyTone 878uv v1) connected to my Alienware laptop. For now I'll stick with the older driver. Thanks all for figuring this out!

 

EDIT: It looks like the older version no longer works with Win 11 (Version 21H2 OS Build 22000.493).  I'll give the latest driver a go.
