Hi all,

I have 5 USB minders:
1 x AntMiner 1.6Gh/s
4 x Block Erupter ASIC Mining BTC 333 Mh/s

I am using cgminer and 10 ports usb hub.

- When I plug in only 4 Erupter and strt the miner everything seem to function perfectly fine.
- If I plug in all 5, sometimes AntMiner and one of the Erupters work, but none of the others; sometimes only AntMiner and the rest throwing errors.

What would be a problem and how to overcome it? Is it even possible.

Thanks,
Alex.
