Ok, nice to know that it works.

Do you use the default vendor-/product-id? Maybe it would help if you use a
different product id that the d2xx-driver doesn't know about.
You can ask FTDIchip, they will usually provide you with a unique product id
out of their range for free.

The async-mode of libftdi is an evil hack which I wrote when libusb-1.0 wasn't
available yet. It would be nice to replace it with something based upon
libusb-1.0. I currently don't have the time to do that, but if someone wants
to work on it we could certainly provide some help and feedback.
Actually Jie Zhang wrote that he is working on it some days ago, you can
search for his post the mailinglist-archive.
