This error is because the miner temporarily lost contact with the USB port, this happens on cheaper hubs...especially if you have the sticks vertical mounted. The vibrations from the fans can cause the port to lose contact with the pins inside the USB connector. Unfortunately a USB disconnect is not recoverable and it would need to be unplugged/replugged.
okay this is a 4x PCI-e slot card to 2 USB ports connector that does 2A per port with a SATA cable connector for power. It worked great at first then started having this issues after about a month. I have been dealing with it rebooting the program every half hour. I had a power outage last night and since then I have had issues. So I will double check the connections and see if something came loose.
