correct settings for cgminer 4.9.2
bmsc only works with the BITMAIN cgminer...

I have fully tested and configured cgminer 4.9.2, the latest to work with the U3, check out my videos on vimeo and dailymotion, do a search for cgminer and antminer u3, full instructions are included.

I have bfgminer working with the U3 as well....
