We will agree to disagree then. I have never had an FTDI deice do anything but 
work with one singular exception, it was on the end of 2 usb extension cords, 
with the far end devices plugged into a separate circuit, and the hub did not 
survive a very close lightning hit, one of maybe .1 secs between the flash and 
the crack.  pl2303's will not work to my ups, nor will they work for heyu 
about 25% of the time.  FTDI's Just Work(TM) for both.
