OK.  So I've tried everywhere.  First off please don't tell me that my miners are junk...it's all I could afford right now.  Second...I've got 4 Asicminer Block Erupters and 1 Antminer u2 (?).  Yes, they're plugged into a powered USB with a fan on them.  I've tried bfgminer AND cgminer and can't get either of them to work.  I've followed the instructions that i've been able to find...which is few and far between and old.  Can someone please tell me what I'm doing wrong?   
Also, when I do get the cgminer (i think) to run, it says that they're too slow to be an icarus and calibrating, but then I get nothing.  I see that they're working, but that they're not totally connecting.  I have class today so it will be a while before I can respond again...but I do appreciate anyone willing to help me and provide some guidance!
Thanks in Advance!
