I believe my HUB isn't performing to what it says. I got the superbpag USB 3.0 Superspeed HUB,http://www.amazon.com/gp/product/B00W4X3DAA?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00, and when I plug a moonlander in, it wont read on bfgminer. My computer will give the error "usb device not recognized the item has malfunctioned", I thought I received a destroyed miner, but when I connected my other two, it gave me the same error. I connected the miners directly into the computer and they all work.

Yet I'm having an issue of the speeds slowly decreasing and bfgminer 5.4 declaring it "SICK. Does anyone know how I can fix this? Should I increase the intensity?

Also to get multiple miners working at one time, should I run two instances of bfgminer each with its own config or can I put in the config to use two login information?
