Its not that I don't trust the device, but if the ep9302 can do it w/o
adding hardware, thats a better solution. Also, my initial concept has
4 high speed ports, and each port has to be able to pump out 1280
bytes of data every 33ms.

Also, I have not programmed usb before, and did not want to set off
having to learn it (going with the devil I know...). This is only one
small part of the product design.  Anyway, I got the datasheets on the
ft232r, and ordered a couple demo units from ftdi.

My main concern is that I can have both usb ports driven so that the
can both send the 1280 bytes of data in 33ms. I know I can do it with
the serial ports (just slower for now).
