So after playing with it a bit more I went for this command line which seems to be stable but still not hashing correctly.  "cgminer.exe --bmsc-options 115200:10 -o nl2.stratum.io:3333 -u magicstix.mainpc -p x --bmsc-freq 0882"


Still getting Lib USB Errors:

Code:

Then it will randomly goto:

 [2014-11-11 14:02:52] Bitmain detect (6:1) failed to initialise (incorrect device?)

When it does stay stable for 5+ mins (Which is random at this point in my eyes) cgminer reported 3GH/s and Ghash.io Reported 8.03GH/s.   So I would trust the pools report at this point with those command settings.
