there do seem to be (at least) TWO distinct issues:
"Windows 8/8.1/10 are NOT supported in PL-2303HXA and PL-2303X EOL chip versions. Windows 11 and higher are NOT supported in PL-2303HXA/ TA/TB/HXD/RA/SA/EA (EOL chip version)".

and:
"Putty is constatly giving an error „Unable to open connection”. In addition in the device propperties I found an error
1. This device cannot start. (Code 10)
2. A device which does not exist was specified.
A quick investigation gave an unpleasant anwser – PL2303 chips are fake! In the newest drivers Prolific blocked all fake chips and the driver in Windows 8.1 is also blocking my fake pl2303. But there is a solution – you have to install old drivers – version 3.3.2.105".

i've never been a fan of the Prolific devices, having them in practice prove flaky from as far back as the days of windows 2000.
