yup .5A
most accomodating hub i've used so far is the d-link dub-h7

+1

I'm using the same model (newer, black version) it's well built and works great connected to the Pi.

Note that I haven't done tests with the Block Erupters, by now it's connected only to some FPGAs
(powering the Pi itself too)

So my best bet would to use link multiple USB 2.0 hubs but I'm hardly seeing compatible 10-port on that list with enough amps to use all 10-ports.

Correct me if I'm wrong but each USB miner uses .5a, right?

I'm planning to run 30 usb miners with the PiMiner, could I hook up 3 of these 10 port USB hubs (RPi non-compatible) to say 1 D-link hub that is compatible for the RPi?

Will this work?

Unforch, not likely. USB 1.1 devices, like the Erupters, don't work through USB3 hubs on the Pi.
sucks. I wanted to use one as well.

Quick question:

I'm planning to run 30 usb miners with the PiMiner, could I hook up 3 of these 10 port USB hubs (RPi non-compatible) to say 1 D-link hub that is compatible for the RPi?

Will this work?

I plan to add more later.

Thank you for this!

I'm planning on building a PiMiner also...just gather all the parts.

Wish me luck!

Good Luck!

Working on v1.1 now - new features coming soon.

Also - please ensure you're using a USB hub which is compatible with the RPi.
As a general rule - avoid USB 3.0 hubs!

a list of verified compatible hubs can be found here:

Guys thanks for all the help, I got it fixed.
Someone asked me for a screen grab of the .conf file and when I was editing out the login info I noticed something.

The instructions said Update the below template with your mining pool credentials by replacing "PoolAddress:Port",
"UserName.WorkerName", and "Password" with your info, then copy & paste into the nano editor: Well I din't verify it transferred over properly. Roll Eyes

There were some line break errors. I fixed those and it's up and hashing away.

hrrrmm … possible you have another instance cgminer running in the background?

Your best bet is to reboot the Pi and try running cgminer normally (not in background) using:

sudo ./cgminer-3.1.1/cgminer --config /home/pi/cgminer.conf -S /dev/ttyUSB0 -S /dev/ttyUSB1

If cgminer runs into an issue, it should display an error.

Occidentalis this time but I tried Raspbian and had the same problem.

As far as the USB hub, I have used it for several things, and never had an issue. I'll try it without the hub and 1 miner.

And it's a powered USB hub capable of supplying a full 500mA to each port?

Yea the Hub is on the list. Trendnet TU2-700. It has a 2a power supply.

Oh yea I remembered I cant try it without the hub. No power in the main USB header.

Yea 2 usb block erupters miners they showed as usb0 and 1.
Edit: same ones from the tutorial. The also work fine on my PC, so I know it's not an equipment problem from that side.

you're using Raspbian or Occidentalis?

Ask here for troubleshooting help? If not I'll edit this out to keep your post clean.

I ran through the Adafruit tutorial with both the Raspbian and the Occ distros with the same results.

I get to the part where you start cgminer and then PiMiner and nothing seems to happen. The LEDs on the USB sticks stay solid and the LCD says "no connection to cgminer"

Thanks
Rotor

k, it looks like cgminer was unable to start mining and therefore exitted/quit

So just to confirm, you have 2 miners connected?
you can double-check by entering:
ls /dev/*USB*

EDIT: also - what type of miners are you using - ASICMiner Block Erupters?

You can OC the rPi all you all you want, it's still going to be slow. It's an ARMv6 CPU. They've been using ARMv7 for years now, and ARMv8 is coming out in the next year or so (gonna be sweet!). That's like OCing a PIII to compete with an i3.

apparently you 'can' overclock the CPU - i dont know how or to what value - i'd definately investigate cooling - as i've seen people say they've over clocked to 800mhz

just googled and found this:

http://www.jeremymorgan.com/tutorials/raspberry-pi/how-to-overclock-raspberry-pi/

1000Mhz and much improved RAM speed? I think thats a win BUT i'd definiatly want a cooler on the chip Wink

Trouble with that is that overclocking often corrupts the SD card requiring a complete reinstall. Gonna be a bit of a pain if your miner goes down cause of this, mine is at 975 core/475 cache/500 mem with +0.15v Heat shouldn't be too much of an issue; it only gets to 64 degrees even with a little aluminium ramsink and a sealed plastic case (see top post on this page) after 3 days of LTC mining on the CPU. But I certainly won't run it this way for long!

When I send it off to the datacentre it'll definitely be back to stock - not worth risking it; the performance is so low anyway, even 30% more is still really slow!
