So as the title reads, I bought 6 of the asicminer block eruptors along with an arctic breeze usb fan and a powered hub just for the fun of it. They run fine for a couple of hours but then they all go dead/zombie.

1) Why do they go into dead/zombie status?

2) Anything that I can do to remedy this?

3) If not does anybody have a script(windows) to reset them and take them out of dead/zombie status?

TIA
