Counterfeit FTDI chips?

Hi,

I have an Olimexino-328 with an FTDI chip with week code 1213. As reported in this thread it doesn't work with FTDI drivers newer than 2.08.14.

In light of the recent FTDI decision to brick counterfeit chips, I'm concerned that the reason my chip doesn't work with the newer drivers is because it's counterfeit. I'm hesitant to attempt to upgrade my system drivers to find out!

Will any Olimexino-328 boards be bricked by the new FTDI drivers? If there's any danger of the board not working in the future due to inadvertent driver updates then there's no way I can use it in my application!

The FTDI chip on my Olimexino-328 (Rev C) was "bricked" by the new Windows 8.1 FTDI driver.

Easy way to restore the chip is to use ft232r_prog from http://rtr.ca/ft232r/ft232r_prog-1.24.tar.gz on Linux

.. disconnect and connect Olimexino-328 here

My 328 with a '1213' FTDI chip works fine on my Win7 64bit. No problems, no bricking.
I have the 2.8.14 driver installed for 328 use, though.
