Specifically this Anker USB hub listed here http://www.amazon.com/Anker%C2%AE-Uspeed-10-Port-Adapter-Aluminum/dp/B007ZWFKX8 . I have had no problems running 10 miners on this one style only. It has a 12V 4A Power Adapter plus Smart chip power management allows devices to communicate idle states and latency tolerance for progressively lower power states and subsequently increased performance and power efficiency. Most USB hubs are less than 4A . The trick here is that you get the 4A(which wouldn't quite be enough to run 10 miners) AND 12V(instead of common 5V) which is plenty together for 10 miners.

Reply sent. Let's get the group buy orders coming in. Thank you for your orders!

Confirmed. Thank you.

Confirmed and greatly appreciated. PM me your shipping address please.

I am awaiting confirmation from friedcat that this has shipped. I will update when I get a reply from him.

Yes. Try the Anker brand USB hubs that hold 10 that have a better power supply than cheaper hubs. I will post a link later and maybe a picture or two.

Store is closed. Please buy USB miners in my group buy, upcoming auctions, or PM me to make a purchase.

The first mass production batch (sapphire) has finished its PCB production and assembly today.

It has significant improvements in:

Heat reduction: 500-510mA (sapphire)

Stability: We stressed it with 9 Block Erupter USBs in a row without heatsinks heating up each other in a very dense USB hub with 25C without active airflow. No unexpected (non-probabilistic) HW errors ever happen.

Speed: This comes after better stability. Now the hashrate converges to its theoretical value of 336MH/s.

Appearance:
  SMT machine assembly (sapphire)
  heat-sink front-case 2-in-1 logo-ed (sapphire).
  LED added.
