After a unexpected fall of light power outage, three of my miners started giving various types of LIBUSB error. I tried everything and had no success. If you know how to fix it, enjoy, my loss is your gain.

1x Sierra Board (Just one board 500+GH/s when it worked.)
2x Prospector Board (~500GH/s when it worked.)

I have also one Sierra WaterCooler.

Any offer for the boards of at least 0.20btc 0.50BTC 0.75BTC(current offer) will be considered.
Free Shipping to US48.
