I just receied my 5 singles I ordered on 3/21.  Unfortunately 1 of the 5 appears to be DOA.  I cannot get it to work with cgminer, although the other 4 work perfectly.  EasyMiner_V_1.1_Beta.exe shows No. Processors [ 0 ], while the others show No. Processors [ 2 ].  It also fails all the diagnostics with Done [FAST RETURN FAULT], Unit NOT reliable. Processed: 3, Avg/ Speed: 0MH/S, Errors: 5, Throttles:0. Total time: 0 seconds.

I sent an email to BFL.  Hopefully their customer services handles this quickly.
