Topic: Block Erupter and Raspberry Pi (Read 12275 times)

Just done a couple of mods to my pi to get it ready for a single BE.

Drilled the lid and created a fan mount, and a little breakout board for the GPIO 5v which the fan is plugged into. Fanf floats right above the USB port. Power mods; bypass all polyfuses and add direct power supply to the USB ports. You don't really need a powered hub

Which Rosewill 10-port powered hubs are you using? (they have 4 different models, more like 3 since two of them are just different colors).

My RPi Model B (v2) has been powering a block eruptor directly without problems for over a month now. (Plugged into a 2A USB outlet)

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.


topology looks like this:

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

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

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.

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 it will not.

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.

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

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

does this hub

work with raspberry pi?

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):

https://www.bitmit.net/en/item/48972-anker-usb-3-0-10-port-hub-with-12v-4a-power-adapter-4-raspberry

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?

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.

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

I have tried this - no dice  :/

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

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...

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

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

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

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

Yes, most definitely, using a D-Link DUB-H7 USB 2.0 powered hub: https://bitcointalksearch.org/topic/a-case-study-in-entry-level-mining-224015

Bummer.

Apparently it's a no go.  Wish it did work though, perhaps it's a USB 3 issue …

Has anyone gotten the Anker 10 port hub working with an RPi?  I see it in a lot of photos but haven't heard or read anything about it.  It wasn't listed on the "Official" RPi USB hub list either.

I confirm that with one stick everything works fine. Seems the same problem.

I didn't use the apt-gets (since minepeon is arch linux and not debian based.  Plus it comes with everything you need to build cgminer)

I downloaded 3.2.1 instead of 3.1.1 of course.

Then I added --prefix=/opt/minepeon in configure so that I could swap out the existing /opt/minepeon/bin/cgminer. 

That's it.  His instructions are essentially correct with a version change.

when manually compiling did you do anything different than mr_john a few posts above?

Yes using a manually compiled cgminer 3.2.1 on MinePeon.  Everything autodetects at startup now with no additional switches beyond url, user, and pass.

I'm using 1 Sabrent 7 port hub for 4 block erupters.  Then another Sabrent 7 port hub to power the RPi, a USB fan, and the wireless adapter.

Averaging just under 1.0% HW errors.  My own experience is that HW errors are a function of the stability of the power getting to the RPi and the Erupters.  Hence the separate hubs for powering the RPi and the sticks.  When I tried everything together in different combinations, the HW rate went up drastically.  Sometimes on just one stick.

having the same problem with my 3 sticks here
cgminer 3.2.1
pi and digitus 7port hub (confirmed working with cgminer 3.1.1 in this thread)


the strange thing with this issue is, if I remove all sticks beside one from the hub everything works fine!
any ideas what I could try beside downgrade cgminer?

My raspberry detects the USB sticks and start mining on 3.2.1, but with a lot of errors and declaring SICKS. I am on powered hub though.

My RPI works fine with 3 Block Erupter USBs through a 2A powered USB hub.

my raspberry don't work well with cgminer 3.2.1. I have three Block erupter. there are to many errors

Has anyone got cgminer 3.2.1 working with four or more block erupters on the raspberry pi yet?

You are welcome!

Thanks a lot!!!

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:

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

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

And the config file cgminer.conf looks like this:


hashing away just fine now!

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

Has anyone done a test to see if hardware errors go up (and average mh/s down) when using a Pi vs a desktop?

some info here: https://bitcointalksearch.org/topic/m.2326740

i have a pi and 2 USB miners on thier way - whats the best way to configure this? my pi has been used once or twice since i got it last year

Burned out the hubs. No problem at all with 5 sticks though. Been running 5 per hub for several days now with no problem at all (external cooling - 80 total).

You burned out the block erupter or the hub??

With 2.0 hub(s)!!!

A single PI can handle 45 block erupters decently well. If you view my profile and click on view posts I posted about this with screenshots in a couple times.

How many Erupters can Pi handle?

Without a hub? probably none.

Anybody running BE USB devices *and* Cairnsmore CM1s on Raspbian and MPBM.

That combination crashes the machine when I tried it.

What is the range of hw errors as a percent of accepted shares that you're getting, please?

On my working one it is running at about 0.9%. (IIRC, several other folks have reported getting about a 1% hw error rate.)

One which is now dead and in the process of getting replaced ran at about 10% hw errors for roughly eight hours. Then it died.

NOTE: I had a fan blowing over them. They were both 'warm to the touch'. Not the 'freaking hot' you encounter without active cooling.

Worth noting I have 80 units running 5 per hub on the hubs I mentioned above.. several days now with no problems after I downgraded from 7 to 6 to 5.

Thank you for this important piece of information. I have ordered one of these through an American user of this forum. Looks like I'll have to try something different.

i've got this Rosewill hub on the way... good to know you've got yours to work!

http://www.amazon.com/Rosewill-10-Port-High-Speed-RHB-520/dp/B007ZSKJV0

it's a 3.5A, so i think 7 erupters would be a hard limit

I have it working on a Pi running cgminer 3.1.1 (on Raspbian).  I had to specify -S /dev/ttyUSB0 etc.

I did not have any luck with cgminer 3.2.0 (yet), or with 3.1.0.

I did not try MinePeon.

I'm using Rosewill 10-port powered hubs.  They seem to have no problem powering 6 or 7 sticks (7 on 2 of them, 6 + the Pi on another).

Was anyone able to get the latest cgminer to work? I was also able to get bfgminer but no luck with cgminer.

I have bfgminer working on minepeon - had to compile from git, the one installed by default does NOT work.

I posted some instructions and such here https://bitcointalksearch.org/topic/m.2326740

Oh yes. I definitely need to mention that =) These can only power 5 sticks. I burned two of them out trying 6 and 7 sticks.

Also, block erupters USB run way to hot for not external cooling so don't stress the closeness to much. Its mandatory you cool these or they hardware error through the roof.

Most definitely.

The ports look too close together for Erupter sticks.

This is the hub I would recommend.

http://www.amazon.com/Plugable-Port-Speed-Power-Adapter/dp/B003Z4G3I6

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 didn't have any luck with cgminer either. I had a little raspberry pie and the Anker 3.0 USB hub, and I heard the Anker could have been the problem though. Waiting for a new version of cgminer and a new hub to arrive - keeping my fingers crossed!

They won't work out of the box on the version that is released as of today. I was able to get the current version of bfgminer to run on it but not cgminer.

I posted more on it here: https://bitcointalksearch.org/topic/m.2345214

With MinePeon, does anyone know of the USB Block Erupter ASICs will work 'out of the box'?

Thanks for the help
