USB to Serial (Prolific 2303) Device Cannot Start (Code 10) in Windows 8/8.1/10

Is this a rare situation where a piece of legacy hardware works fine in Linux and is broken in Windows??

The Prolific 2303 works perfectly fine in Linux Mint.  Yet, for some reason, Prolific says that some of these chips have reached the end of life and won’t be ‚supported’ under Windows 8.  Prolific suggests that you purchase their updated chipset (PL2303HX Rev D):

In the resulting dialog, click „Browse my computer for driver software”:

Select „Let me pick from a list of device drivers on my computer”:

Select the Prolific driver version 3.3.2 from 2008:


If all went well, you’ll no longer see the yellow triangle:
