hey everyone, i just got my antminer u1 up and running as a test rig to make sure i could get all my account and wallet settings etc, before i bought a stand alone unit.  it worked for a little while (slowly, but obviously expected) but when i disconnected the U1 to move it to a different USB slot and restarted CGminer i cant get it to run again. i dont think anything changed so could anyone tell me what im doing wrong please?  here is the cgminer window
