Hi All,
I am a complete newb to this hobby and after 4 days of tinkering am extending a cry for help.
I am running 4 Antminer U1 blocks in a Etekcity® Premium 10 Port Powered External USB 2.0 Hub - with 12V 3A Power adapter
which is cooled with a ARCTIC Breeze Mobile USB-Powered 92mm Portable Fan.
I am using MultiMiner 2.3.3 on a Dell XPS 8300 Intel Core i7 CPU @ 3.4 GHz, 8 GB RAM, 64-bit Operating System
MultiMiner has recognized all of the devices, but since I started mining, approx 12 hours ago the Hash Rate of all four devices combined
has never exceded 1.24 GH/s. Each device seems to fluctuate from 0 to 500 MH/s individually with high error rates of up to 50%, but seldom
below 25%. It seems MultiMiner is using CFGminer.
I am mining Bitcoins in the "Slush" Pool.
Below are the lates entries from the three tabs MultiMiner produces.

Looking for any advice as to why the devices are running so slow with high Error Rates.
Thank you all.
