Subject: FT2232H shows up like FT4232H

Hello all,

I have problem with my FT2232H chip:
I want to use it to communicate via sync FIFO. As the data sheet
suggests you have to reprogram the eeprom, but when using the tool
from libftdi I found that the chip id is FT4323H. Maybe someone who
used the board beforehand overwrote the value.
I tried to change the eeprom by hacking the eeprom example of the
actual libftdi version (git clone), but I did not succeed.

Can anyone tell me, how to change the chip id in the eeprom without
breaking the device.

Thanks a lot,
Matthias Brugger
