I have been trying to build a USB-JTAG converter using FT2232D. I have programmed channel A to MPSSE mode as per the app note -AN_110_Programmers_Guide_for_High_Speed_FTCJTAG_DLL using Visual Studio and it executed error free. But when I plug in the device, it is still being recognised as Serial converter. I would appreciate any help to figure out what I am missing.
