I tried to find an answer for this.
I have now tried to mine first with block erupters and then with antminers. I have same problem with both.
I have a powered USB hub with 5 volts and 2 amps power. I put for ex. three erupters in hub. First erupter and last erupter works fine, but the one in the middle does not. I also tried with three Antminers and got same results.
What could be the problem? I see all three in API window, but only the first and last give me results. The middle one gives only HW errors.
It does not matter in which ports miners are, result is still the same.

I tried those miners with bfgminer and still got the same results. I think this might be a driver problem.
Is there any other suitable drivers for OS X or is Silab-driver the only solution?
Or is there some tricks for Silab-driver?
