OK...
So here is my quick review of the GridSeed chips I got from Hashra.
Probably should post this on a separate forum thread.. but.. meh.
In full here is a video: (Sorry for my ugly mug shot there in the beginning of the video.. you have been warned.)

The packages came in very late and I am a little upset that the prices dropped by a lot roughly a week after getting mine. So I feel cheated out of roughly 3+ grand.
But either case Hashra isn't a scam by any means. They are just a little slow. Which is my only real compliant other then the price drop. And hopefully they have fixed the shipping delay problem.
Thanks for the vid, was interesting.
Regarding the USB configuration, can you tell me more about how you wired up the 49 port hubs? Are you using the modified cgminer on the laptop to address all the GSDs in the whole rack?
