Responding to: ???'s previous message
Mentioned it because there were suggestions that the issue could be related to application software. FTDI support guy wanted to have a look at the source code. Anyway, finally he gave me the links to some of the circuits/PCBs on FTDI site, which I had already downloaded for reference.
