[chirp_users] vx-6r redux

[Dave B]

There were even some Fake FTDI chips about a few years ago.

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.

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.

(I've given up with Windows for my own personal and Ham useage, no 
regrets...)

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.)

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.

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.)

You get what you pay for.
