OK, a little about me before I start, I've taken up Bitcoin mining five years too late. I am aware that it's unlikely to make me any money however in doing so I'm learning a little linux, finding out about Bitcoin and generally enjoying my time doing this. I've worked with PC's for many years and consider myself fairly proficient however linux is a different story..
A month or so ago I started Bitcoin mining with my GPU (a lowly 95 Mhash/s) but I thought I was the bee's knee's! hahaha, as I've been learning more I find that statement more and more hilarious. Recently I got a few ASIC's and bolted them onto the front of my PC
Running (via Windows) using command cgminer.exe -o stratum.bitcoin.cz:3333 -u USERNAME -p PASSWORD
Hash rate was just over 1.1 Ghash/s with three Block Eruptors, which I thought wasn't too bad (again in heinsight that is also amusing..)
Then I got myself a Raspberry Pi, fiddled with it (repeatedly over and over until I had achieved what I wanted and boy does it take a long time to rewrite those SD card images. I had to do that at least five times!)
So today my USB hub finally arrived and I removed the three Block Eruptors from my PC and plugged everything together with my Pi.
The power used from the wall socket was a little higher than I had anticipated but that's because I'm using an old BT Home Hub to act as a temporary repeater while I wait for a replacement RJ45 crimping tool to arrive. Also this is peak power and doesn't seem to go above this, normally it's around 4W lower than this but it does fluctuate a little.
So currently I'm running the Homehub, my Pi, a USB Hub and 8 Block Eruptors.
Everything went smoothly until I fired up VNC to ensure the Pi was doing it's job correctly
Running (via Pi) using command sudo cgminer -o stratum.bitcoin.cz:3333 -u USERNAME -p PASSWORD
As you can see seemingly all of the Block Eruptors are taking it in turns to fail, getting disabled, then re-enabled and restarting
Surely this isn't usual (it never did this on the PC although that's not saying much I guess) and I assume something isn't right, the only problem is I don't know what!
I would certainly appreciate your help and suggestions in getting this resolved, I had hoped the hash average to be around 2.6 Ghash/sec although because of all of these interruptions I am currently only getting 1.99 Ghas/sec
