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.
If your running windows, trying disabling the COM ports and re-enabling them. That should clear any driver errors caused by the power down. If that still does not work, sounds like the hub is just not properly resetting and not much you can do about it. You could also install some sort of remote switch/relay on the hub socket and restart the hubs remotely that way.
