Unfortunately the issue that FTDI is trying to combat is counterfeiters,
and I think you will find that the counterfeit devices will report the
same product and vendor id as the genuine ones. The product and vendor
ids are how the OS identifies a device and how they decide which device
driver should be used. Apparently at least some of these counterfeit
devices are not perfect copies or else a device driver would be unable
distinguish them from genuine. It is like a number of years ago when
cable TV companies where having a lot of trouble with counterfeit cable
descramblers, they found a flaw in the code used in them and transmitted
what became know as a "magic bullet" that caused them to fail.

Before you buy it yes, you can't know. But it's trivial to find out
after you own it. For example click the Apple logo then choose "about
this Mac" and the data is there. For example it says this random USB
thumb drive I have is
Product ID: 0x3260
Vendor ID: 0x0aec (Neodio Technologies Corporation)
Version: 1.00
Serial Number: 20040602032741578
This same exact information is logged every time the device is
inserted to my Linux system too. I assume MS Windows will tell you
all the vendor info as well.
The vendor IDs are handed out to manufacturers by an outfit at "usb.org".
So, check your devices. It's not hard to find out about the ones you have.
This is pretty insane actually.
I buy products that I believe are legit no way to know just as if the cpu
in my acer or emachines not legal. Heck I have no idea.

Short story: FTDI released a new version of their USB driver (via
Windows automatic updates no less) that bricks other vendor's compatible
versions of their interface chip. They also updated their license file to
indicate that this may happen... except you never get a chance to decline
the new license with automatic driver updates. I can just hear the class
action lawyers drooling...
