   Not sure if this works, since I don’t own a bus blaster.

   Based on libftdi’s example bitbang_ft2232.c
   Uses libfti which is available on linux/windows/mac.

   Since MSPPE is 16 bit wide I tried using two ports.

   Maybe it’s atleast a starting point

   /* bitbang_ft2232-busblaster.c

   based on FTDI’s bitbang_ft2232.c

   Thanks to max@koeln.ccc.de for fixing and extending
   the example for the second channel.

   I just sent you (by e-mail) a Qt app for testing.
