Michael, yes, i'm trusting the firmware on the chip connected to the FT245R to report accurately whether or
not it's receiving data
and yes , it has worked before.
Before i was using the D2XXX library to talk to the device ,
As far as i know, I am doing anything to enable RD# ,
do i need to do this?
i don't have direct access to the chip, as it is embedded in device.
Also, i tried writing twice as per Alex's suggestion , and this didn't help
-Howard
btw, the reason i'm trying to use the libftdi library rather than libftd2xx.so is so
i can try to compile the code for a Gumstix processor .
thanks...
