Hi all,

I am the next one asking for some help  Wink
I almost read all of the pages in this post but I am not able to get the Compac Miners from Bitshopper working as expected.

I am using this hub: http://www.amazon.com/ORICO-Charging-Adapter-Windows-H10C1-U3/dp/B00HSHN82K/ref=sr_1_4?ie=UTF8&qid=1453394936&sr=8-4&keywords=orico+10+port
with two miners in it.

I am also using bfgminer with compac support enabled.
The usb hub is running on my Linux box (standard desktop pc) because I am running an Bitcoin full node so there is no need for me to take one of my PI's for it Wink

Both sticks are just running fine with .674V and 125MHz. But then the speed is "just" 8.26GH/s per each miner. I tried almost everything (spinning the potentiometer with setting the MHz to almost everything between 125 and 300). I can get the sticks running very well with different configurations and about 16 to 17 GH/s average. But after 10 minutes the sticks stop working, no hardware error or something like this.
I even dont see any message using journalctl stating that the sticks are disconnected.

Does someone has a hint for me what I can try next to get more hash power out of these miners?

Thanks

on that hub you are limited to 0.9A/slot, which is probably why it does not work at some settings that you tried. Solution-a different hub (Anker with up to 2A/slot works fine on Linux) or Y-cables (cheaper). Search Y-cables on this thread-there are dozens of posts. something like this:

EDIT: nevermind re Anker-I forgot that it has regular slots also at 0.9A. the ones that have 2A/slot are Superbpag (some people say that it is called simply PAG now) and Plugable:
