Hey,
Next time before you buy something better think twice before jumping into china miners
What about the original software is it working?
I was playing with grind seed units just once grind seed chip
I can tell you that I was mining happily for hours and cgminer fork of greendsed was showing me hashes flowing when USB was not working at all
These guys are funny
So chose what you buy wisely for the feature
Never buy something with close source that is all
