Curious: for an FTDI, why use serbb? It's among the slowest possible
options. Don't you have the possibility to use FTDI's MPSSE? All it
requires is one of the supported chips (see the FTDI website), and
the presence of libftdi (which is opensource) on your system.
Since all the bitbanging is then handled inside the FTDI chip, this
is going to be way faster than serbb which has to complicatedly
transfer full USB packets for each single bit change.

Never trust an operating system you don't have sources for. ;-)
