There were even some Fake FTDI chips about a few years ago.<br>
<br>
In Windows, use the Device Manager to view the list of connected
devices. Look under printer & serial devices, if a Serial
device is marked with a yellow warning triangle with a ! in the
middle, there is a problem between the driver and the device itself.<br>
<br>
I've come across some fake IC's that were marked up as FTDI, but
identified themselves to the OS as Prolific! So, obvious fakes.
(Though on a Linux box, they did work OK as Prolific devices.) That
was for a work project too, we got our refund though.<br>
<br>
(I've given up with Windows for my own personal and Ham useage, no
regrets...)<br>
<br>
I wanted FTDI specifically, as you can program the behaviour of the
status lines, and also the "sense" of the data lines. I needed the
TX data line inverted from normal (to accommodate an Fibre Optic
sender, but the RX line left as default, as the FO RX device doesn't
invert the data, in that configuration, with the pre-existing TTL -
Fibre interface boards I had to use.)<br>
<br>
The Fake FTDI chips allowed me to do that without error, but did't
actually make the changes, or "stick" the settings in their internal
memory.<br>
<br>
If I need any USB-Serial bridge products, I now only buy from FTDI
direct, or from reputable sources (but of course, the cost is higher
than the "other" sources.)<br>
<br>
You get what you pay for.<br>

What data lead were you using? If it uses a Prolific
USB-Serial <br>
bridge, it may be an old type of chip, or a clone. Either way
Windows <br>
(and many Mac systems) will not use them. (Without
compromising the <br>
security of your system by blocking automatic updates and then
manually <br>
installing an earlier driver suite.)<br>
<br>
But Linux (even recent distro's) use them just fine,
regardless. Had <br>
similar issues locally, with a group that uses dozens of
Baofeng <br>
radios. All the interface leads used "hookey" chipsets. A
Windows box <br>
and a Mac, both failed. My old Dell running Mint, "just
worked"...<br>
<br>
Counterfeit IC's are rife in that part of the gadget after
market.<br>
<br>
Take care.<br>
