How comes you have so low HW rate?
My ANTIMNERS are running at 2GHS @ diff 8. and i have about 150 HW to 1000 Accepted shares.
What do i do wrong?
The Antminers are powered from SUB3:0 hub with 4 A output.
The hub is connected to the USB2.0 port on my PC, but i assume that there is not so much data to transfer, so speed shouldn't be a problem.
Miners are pretty well cooled to about 35 C°
What am i missing?

I have 30 u1 oc @ 2GH/s :
one has a lot of HW err ( 13 %)
bot others have less than 1% HW err
