Block Erupter and Raspberry Pi

[nubbins]

is anyone running thier Pi and USBASICs off the same USB hub? or is it recommended to run the Pi off a seperate PSU?

I'm running five erupters and my pi off a Rosewill hub with no problems.

rosewill hub? i've only heard of ankers and the dlink hub... how many ports do you get on the rosewill?

BTW is there a list of test/working hubs for RPi mining? im using my PC atm but wnat to move to my RPi for obvious power saving reasons

Just for the record:

Raspberry working fine with 3 eruptors using cgminer 3.1.1 and this hub:
http://www.digitus.info/en/products/accessories/usb-hubs/usb-20-7-port-hub-da-70222/

This hub is a 7-port hub, but only 5 eruptors will fit in (I actually tested the hub on my laptop with 5 eruptors for about 2 hours). Now it's running stable with 3 Eruptors on my raspberry (as only 3 of the 5 eruptors were my own).

To compile cgminer 3.1.1 on a current raspbian system I just did the following:

Code:

sudo apt-get update
sudo apt-get install libusb-1.0-0-dev libusb-1.0-0 libcurl4-openssl-dev libncurses5-dev libudev-dev 
wget http://ck.kolivas.org/apps/cgminer/3.1/cgminer-3.1.1.tar.bz2
tar xvf cgminer-3.1.1.tar.bz2
cd cgminer-3.1.1
./configure --enable-icarus
make
# and do a short check if the binary is running:
./cgminer --verbose --text-only

Check that user pi is part of the group "dialout" so it can access the device files /dev/ttyUSBx:

Code:

pi@raspi1 ~ $ groups
pi adm dialout cdrom sudo audio www-data video plugdev games users netdev input

For starting cgminer 3.1.1 with 3 eruptors I use this commandline on the raspberry:

Code:

./cgminer  --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S /dev/ttyUSB0 -S /dev/ttyUSB1 -S /dev/ttyUSB2 --config /home/pi/cgminer.conf

And the config file cgminer.conf looks like this:

Code:

{
"pools" :
        [
                {
                "url" : "http://stratum.bitcoin.cz:3333",
                "user" : "<my user>",
                "pass" : "<my pass>"
                }
        ],
        "expiry" : "120",
        "failover-only" : true,
        "hotplug" : "5",
        "log" : "5",
        "no-pool-disable" : true,
        "queue" : "2",
        "scan-time" : "60",
        "temp-hysteresis" : "3",
        "worktime" : true,
        "shares" : "0",
        "kernel-path" : "/usr/local/bin"
}

hashing away just fine now!

[edit]
corrected wget command to correct link for cgminer 3.1.1
[/edit]

Thanks for the step-by-step! Just got my Erupter mining away on my Pi. Only tweak I had to make was eliminating the "http://" from the "url" string in cgminer.conf

is anyone running thier Pi and USBASICs off the same USB hub? or is it recommended to run the Pi off a seperate PSU?

I ran two USB Block Erupters, and the Raspberry Pi of the same hub (D-Link DUB-H7, power the rPI off on off the charge ports. Hub does not backfeed on the uplink, so works great with the pi).

Only problem is that with the current minepeon, only cgminer runs the Block Erupter, and only bfgminer runs the Jalapeno. So I moved my Block Erupters to my main computer...

[southerngentuk]

The Anker hubs definitely do not work with the PIs. I picked up 5 of them which I have to return because I want to go pure PI based. They partially work and look sexy. On a USB 3.0 machine they work great though.

I have ordered a hub that looks like the Anker Just a thought, has anybody tried a usb 2 hub between the Pi and the Anker, Would this work?? Pi-USB2-USB3

Damn, Thanx for letting us know...I`ll try a few things when my hardware arrives....

I'm running five erupters and my pi off a Rosewill hub with no problems.

Sorry, I'm only seeing this now.

I think Rosewill is newegg's in-house brand. Mine is a 10-port, 3.5A (model RHB-520). There's a switch to enable all 10 ports or just the first 6, but I'm not sure if this causes a drop in the first 6 ports, so I've left it off. 6 was fine for me, anyway, as I only had 5 erupters and the pi.

For the record, that specific Rosewill hub wasn't listed in the RPi compatibility charts, but another Rosewill model was. They probably all work.

[macromode]

I discovered this Rosewill usb hub, RHB-500 http://www.rosewill.com/products/1543/ProductDetail_Overview.htm, that might adequately power at least as many as the RHB-520 due to its power supply giving 4A. And it's not a USB 3.0 hub so I suspect it'll play nice with RPi as well. Anyone have reason to doubt its suitability?

[mrgool]

I'm waiting more Erupters from www.asicminer-shop.de
I hope will lunch 16 Erupters on my Raspberry before WE.
Currently 10 work just fine:

BTW I'm selling this ANKER HUB now (working with Raspberry, used ~ week):

I was looking at that one before.. couple different manufactures have it.. the usb ports themselves look way to close together..

[platti]

you can stick 3 erupters on each side, then you have one  ampere reserve (6 sticks = 3 A)

Hey everyone, would the raspberry pi offer sufficient power to run 1 USB Block Erupter?  I will be receiving my first device later this month, and plan to use strictly one unit with the pi for a while.  I currently use a 1.2 A usb power adapter for the raspberry pi.  Thanks.

No it will not.

Maybe (depending on the voltage) - I had a rPi+BE running, but using a 2A/5V Power Supply, 1.2 might be high enough ... W=V*A

For stability and ease-of-remote-reboot, rPi+PoweredHub+BE(on hub) would be the way to go

No, the maximum power the USB port of a Raspberry Pi can deliver is 100mA.
There is a fuse that blows if you ask more.
You need a powered usb hub.

[volosator]

my pi doesn't work with any hubs I have.

I have old trendnet and some noname usb 2.0 hubs, both have external power. pi detects hubs and 'lsusb -t' shows correct topology. sticks run for 2-3 seconds, then I see hashrate drop and then pi hangs when I kill cgminer. then, hardware watchdog reboots pi and I get to try again. I can run my sticks on PC just fine using any of my hubs. I ordered DLINK DUB-H7 hub - this one works with pi, i've seen many pictures online proving that.

i will post more when I have updates

[-Redacted-]

Switch back to cgminer version 3.1.1a and I think you'll have better luck. 

[volosator]

Dlink DUB-H7 arrived today; plugged it into Pi and seen exactly the same behavior I've seen before.

Downgraded to cgminer 3.1.1 and everything works great, USB sticks seen as ICA0..3

I guess the issue is with cgminer direct access to usb port. 3.3.1 doesn't work, 3.1.1 works.
