problem with using different miner types on the same USB hub

[ShurikAg]

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.

Power supply isn't strong enough on your hub.

Really? It's built for 10 devices, it does not work for more than two...

The hub is built for 10W

AntMiner is 2W
Erupter 2.5W

Should be enough for at least 4 of them. With AnMiner only one more work. However, if I use all 4 Erupters, all of them functioning.
Does not make sense.

Bitcoin miners use more power than USB Flash drives, printers, keyboards and the like.

Well, I just checked the specs for them.
However, I also rechecked the specs of the power adapter. Apparently it's 5W.
Seems like you are right... 

Thanks,
