I have a setup that was running fine in the past. I can get it to run on the older version of minera but eventually it stops responding but still mining. Then eventually it quits mining. I was excited for 0.9.0. However when I connect all my gridseed blades and try to restart the miner to get them going it just sits there updating. I have them on usb hubs that you can turn off/on in banks of three. I can get minera to start on 15 of the 18 blades (9 miners with 2 blades each.). I thought maybe it was one of the blades causing issues. But I tried isolating them by sets of threes and they seem to all work. Any help would be appreciated. Edit to add this is on a RPi 2. I ordered a RPi 3 to see if that helps.
