All have done is wire-wrap the pins for bus powered mode. I am using
libftdi version 0.16 in bit-bang mode. I downloaded it about 2 weeks
ago and see some changes in the repo I might download to see if they
solve the issue. The pattern is interesting though and each port
works fine until you access the fourth port then the first port you
accessed now seems to control the fourth port you accessed. Once you
have touched the fourth port the 3 ports work as expected regardless
of the order accessed and the 1st port remains an alias to the 4th
port. If I can find a couple of hours this weekend I plan to do some
more testing but as for now I'm stumped. It would be really cool if
someone else could replicate this behavior though because right now
I'm still not convinced I don't have something else wrong with my setup.

the example bitbang_ft2232.c (substituting 6011 for 6001 for
the device id), and also using a copy i've been modifying for
my purposes, which only opens one interface, i can get success
on interface B, but not on interface A.
Hi Paul, what version of libftdi are you using? I've been able to
test the serial operation of all ports successfully by tying rx/tx
together. I haven't tried GPIO on interface A yet.
