hi jeff,
sorry for the elementary question but I have 20 of these on the way and need to know exactly what type of USM cables I need to hook these up the the hubs I've ordered.
i think you will find everything you need to know (and much more!) in miaviator's complete guide:
https://bitcointalk.org/index.php?topic=494625.0@miaviator excellent guide by the way! respect.
i didn't follow up on mining with gridseed by the way, because a few other things distracted me recently.

my single gc3355 is now sitting in a box doing nothing. :-/
