I have one of the new 2xBM1384 miners.

Using cgminer (it appears there as one AMU GS-10008) I don't seem to be getting anything above 530Mh/s or so. I increased the Vsupply to something around 0.7V (no multimelter, just turned it clockwise but not all the way).

I've tried frequencies 200 - 350MHz, none seem to give much higher hashrate. My USB hub is only rated at 1A, I suppose the problem is I need higher current supply?

I'm mining at kano.is, although it seems this isn't the best to use with lower powered miners.
