Did you set the timeout to a short period? Did you try to terminate the
sequence with a "send immediate". Otherwise the FTDI may take a long time
until the chips decides to flush the few bytes in the buffer back to the
host.
Otherwise post a small example against the example directory so other can
have an easy look at the problem.
