[pyusb-users] Accessing FT4232

Hi,

I'm have been unable to access the 2nd, 3rd or 4th port of the
FTDI FT4232H. I can successfully bit bang or use SPI on Port A.

I am currently using pyftdi, but I"m pretty sure I'm missing the correct
information for pyUSB. I am using the following:

self._gpio.open(vendor=0x403, product=0x6011, interface=1,direction=out_
pins)

I thought changing the interface would work, but both 0 and 1 access Port A
and 2 gives me
GpioException: Unable to open USB port: No such FTDI port: 2

Can someone point me in the right direction?

thanks,
Geoff.
