Topic: FTDI driver via Windows Update bricked counterfeit devices

"The FTDI FT232 chip is found in thousands of electronic baubles, from Arduinos to test equipment, and more than a few bits of consumer electronics. It’s a simple chip, converting USB to a serial port, but very useful and probably one of the most cloned pieces of silicon on Earth. Thanks to a recent Windows update, all those fake FTDI chips are at risk of being bricked. This isn’t a case where fake FTDI chips won’t work if plugged into a machine running the newest FTDI driver; the latest driver bricks the fake chips, rendering them inoperable with any computer."
"Because the FTDI USB to UART chip is so incredibly common,  the market is flooded with clones and counterfeits. it’s very hard to tell the difference between the real and fake versions by looking at the package, but a look at the silicon reveals vast differences. The new driver for the FT232 exploits these differences, reprogramming it so it won’t work with existing drivers. It’s a bold strategy to cut down on silicon counterfeiters on the part of FTDI."

Well, i might need to include that driver, which is available directly from FTDI as "CMD v2.12.00 WHQL".

Yes, the Terms are included in the .Inf.  It is also apparently only a "soft" brick, as you can download their firmware tool & reprogram the HWID's, providing you know what it was ...

Apparently, a competing product, Prolific's PL2303 drivers simply register "Code 10" for counterfeit devices.

What do you, the reader, think?
