great.
I'm currently awaiting my device, so I can start hacking.
Mebay I need to build me some "special" USB cables to work on the 
FOTG-USBdriver.

So they are three extra pins, not covered by Faradays IP, for each USB 
port. I have a (small) vision about the layout, but I need this NAS.

Oh, and for the soldering :
This is a piece of cake, part of my day job.
