Yes, you're right my comment was too broad, I meant "all other cables
I have tried were junk". I dont mean to imply FTDI are the only good
ones... just the only good ones I know about.
But it was cables with Prolific chipset the ones that made me go
through "drivers hell" on Windows machines. Prolific says on its web
page that there are copied versions of its chip set, and that because
of that newer drivers detect "fake" ones and refuse to work.
"
Warning Notice: Please be warned that counterfeit (fake) PL-2303HX
(Chip Rev A) USB to Serial Controller ICs using our name, and device
drivers, were being sold in the China market. Counterfeit IC products
show exactly the same outside chip markings but generally are of poor
quality and causes Windows driver compatibility issues (Yellow Mark
Error Code 10). We issue this warning to all our customers and
consumers to avoid confusion and false purchase."
Well, if a company cant protect its IP or fight knock-offs being sold
in the open market, and not a dark street corner, it s certainly a
firm I dont want to do business with. "Avoid confusion and false
purchase"... the nerve of this people! how am I supposed to know? Have
they heard about holograms? (like some Taiwanese wifi vendors
implemented), or codes I could enter on its web site to check?). They
say nothing about that, so I guess you buy a Prolific cable and you
mightas well flip a coin to know if it s legit or fake.
They cant even speak English for Gods sake. What is a false purchase?
a purchase made by con men, that doesnt actually happen? a visual
trick?.... ohh they meant "avoid confusion and the purchas of a false
unit"... now I get it.

I dont know if that was the cause, but most of the Made in China USB
rs232 cables available for cheap down here have a Prolific chipset
inside. I had to go to great lengths to find ones with FTDI
chipset,and the difference was day and night, flawless operation from
minute one with FTDI. Drivers hell with Prolific.
My suggestion remains, unless you buy something with a "known good"
chipset like FTDI, chances are, you are asking yourself for trouble.
I hope you dont work for Prolific or one of its distributors and felt
offended, but thats my experience. If you ever visit Argentina and
drop by you can have the 4 or 5 JUNK CABLES that are taking space in
my drawer.
