I'm not sure what you mean exactly. However as a guess -> I am not familiar with these boards.
This is all on a Unix/Linux system. Get a USB hub. Connect them all to the USB hub via USB connections. Run cgminer with the relevant FPGA support compiled in an point them to your USB ports. With cgminer pointing to a pool of some sort and configured for with your pool login/miner details and off you go.
I'm sure somebody will correct my mistakes and or oversights.
I want to try to usb, but I think the result is not optimal
