Perhaps this is the problem...the FTDI chips have the odd 
characteristic that the WRITE strobe is active-high, rather than the 
otherwise universal active-low standard.  The FTDI write pin is 
normally held low, and should only go high as a write strobe.  The 
READ pin uses the normal active-low convention.  On boards I pull the 
WRITE pin low with a ~20k resistor.
