sunk818, racebyu I have a laptop connected and i have two separate hubs for 8 USB sticks MLD2. The problem is that if power failure and after comes back even if i connect remote to laptop and restart bfgminer i still get FutureBit write error after 2-3 minutes. And to get them run again i have to restart hubs and is need to be there.
The laptop still run on battery after power goes down. I don't know if i can find a solution.
I had same problem before too. There's no solution. Quit bfgminer, turn off hub, turn on hub, start bfgminer.
How often is this happening? The reason it happened to me is that USB HUB could not handle 10 ML2. I have 8 ML2 running at 744. Even though hub says they can support 120W, I think it is a lie and real wattage is closer to 70-80W. So many quality problems from unknown brand China made electronics. (Talking about hub, not ML2. ML2 is solid engineering!)
