I forgot to ask a few things....

The USB Hub IC and JM20329 chips, what is the minimum Quantity for the
reported price, and how many ports are enabled by each IC?

As for the FPGA, how complex would it be to rework numerous opencore
designs? Some of the designs I am talking about are these
projects...usb 2.0 core[1], a Serial ATA controller [2],  SPDIF
interfaces[3][4] and AC'97 [5] interface. And finally, How fast of an
FPGA is truly needed for each task.
