The new patch for cgminer is very nice.
There is any solution to restart the USB device? All 6 device work nice for a while, then _random_ one or more device performance fall down drastic. I have tryed restart the cgminer, but this is no solution, they still work with low performance continue.
They dont work normal, until i unpower the boards.
I have hex16a2, MTT USB hub. Enough PSU power.
