one should pick FTDI over Prolific because of all the Prolific<br>
counterfeits in circulation. It seems that this is now becoming a<br>
problem with FTDI, as well.<br>
<br>
Up to now it was not a problem for the end-user. FTDI has decided to<br>
change that with their latest driver, which changes the configuration of<br>
a "fake" FTDI chip so that it is rendered useless (at least without a<br>
bit of fiddling with configuration tools and device IDs on Linux or XP).<br>
<br>
I hadn't realized that FTDI had such an issue with fake chips until I<br>
read this article. Some of the comments point out that the end-user of<br>
the device has no way of knowing whether the chip is genuine or not.<br>
Further, as noted above, many in the radio programming community<br>
purchased devices touted as having FTDI chips in good faith as an effort<br>
to avoid the counterfeits Prolific chips.<br>
<br>
Anyway, if you suddenly have issues with your FTDI USB-to-serial<br>
adapter, take a look and see if the PID has been changed to 0. If so,<br>
then you may have been affected by this new driver.<br>
