Dear Bob

You do need to qualify that statement a little!

Whether or not a Prolific adapter will work does depend on which Windows 
system you are using

For my work I have W7 and pretty much every adapter in my "tin of 
goodies" works

On my shack PC and personal laptops I have W10 and every Prolific 
"fails" while all the FTDI ones are OK.
