You didn't specifically say so, but I assume that you removed the ftdi_sio
module before running xc3sprog?  Because that's one obvious way to prevent
it from working.  The low-level calls will fail if the serial device driver
has control of the device.

If that is not the issue, then let me know;  I have some other suggestions
concerning the description string in the cablelist.txt file.  I have not
tried accessing the default FT2232 (with its original internal description
string) using the "-c ftdi", but if the above comments aren't the solution
to your problem, I can check how this works on one of my boards.
