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. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
