Has anyone figured out why one or more miners do not hash( shows 0 K hash/s and 0/0 blocks)on the dashboard. It seems like the usb hub is not working correctly. In my case it is only one miner but I had them all working and hashing , then after 24 hours of hashing, one miner always shows 0 k hash/s. I know it is not the miner, I checked each one individually.

Update: This morning I checked and just before they restarted themselves, the miner in question was mining at only 5 k hash/s and the rest average 325 k hash/s, after self reboot the same miner is at 0 k hash/s again. Any suggestions would be appreciated.
