I've done I2C using the FT245 using the libftdi library in Linux: http://www.intra2net.com/de/produkte/opensource/ftdi/ Very slow at reading since the USB latency kills performance. But writing is ok since you can assemble large chunks of data and send it out in a single USB packet. I believe there are some libraries for Windows that use a different (D2XX?) mode that will give you better performance.
