Title: powered USB for antminer and BE Post by: zipman on February 17, 2014, 02:18:07 AM I am just getting into the bitcoin mining and I did have a powered usb hub that I had my raspberry pi and I had an antminer. the antminer fluctuated and would not be steady over 1000 hashes. I tried putting in a BE that I had bought and they both worked but together they did maybe 1000 to just a bit over. Someone on another thread suggested that my usb hub was not strong enough so I looked at the specs for it on the manufacture website and right on the page it stated it will not work with asic mining. so I went back to my computer store and found a nice powered usb hub that runs 5v and 4 amps. The thing is that it is a 28 port usb hub. I am just wanting to know as I expand and buy more antminers will I have a lot of unusable ports that will go to waste because of the power drain from the antminers? If so what would be a good investment for a usb hub? I guess if I have too I can just use the big 28 port as a central hub for other usb ports for transferring the data thru to the pi. Please help with my delima. Thanks in advanced

Title: Re: powered USB for antminer and BE Post by: zipman on February 18, 2014, 12:02:41 AM yes its a usb hub, each port has its own on/off switch. being that its 4amps and I think I read somewhere that an antminer or BE uses .5 amps which means I will only be able to use 8 of those usb slots correct? I guess I will find out when I eventually put in a 9th miner
