This probably isn't enough to make the devices work.

The FT2232H and FT4432H are High Speed devices with defaul buffer sizes of
512 bytes. A recieve buffer contains two status bytes and then up to 510
bytes of data against 62 bytes on the old devices.

Shame on me. I did only check whether the device with its four channels are
registered. Since the chip is built-in on our board and I still need some
additional libraries to check the devices connected to it. I haven't done any
function tests still. Will keep an eye on this. Sounds that it could be a little
hairy then. Afais the PID 6001 is e.g. shared by common/high speed devices. I
didn't grab deeper in the ftdi code, probably it'll be some way to work around
this.

cheers

For libusb access, some work for the H-Type chips has already been don in
libftdi (www.intra2net.com/en/developer/libftdi/)
