Okay, I lied. That /did/ happen to me once -- but I didn't blame the 
FTDI driver.   I blamed my five year old laptop that had never been 
defragged or had its OS refreshed. <g>

I had to remove the battery, and then deliberately unplug the PS. 
Laptops don't really have anything other than a soft reset button which 
they call a "power" button.  But it takes software somewhere to 
recognize "Oh, he held the 'power' button down for five seconds -- that 
means actually shut off now"

Unless your power management settings say that it means hibernate, 
instead. Like mine did. yeesh.

That was my configuration when the above occurred.
