Good idea -

I ordered 7 units, and plan to use the following gear.  Will post pics and updates when the whole thing is running.

Platform - Raspberry Pi Amazon
Hub - D-Link DUB-H7 Amazon
Network - Edimax EW-7811Un Amazon

It's important that if you plan to run on RPI you should consult the list of verified powered hubs which can be found here http://elinux.org/RPi_VerifiedPeripherals#Powered_USB_Hubs


I received my Erupters this evening and I have some more data to help similar users.

I am using the Raspberry PI to mine with MinePeon http://mineforeman.com/minepeon/

I had to manually configure wlan0 using these instructions https://wiki.archlinux.org/index.php/Wireless_Setup
The wireless driver is already included in MinePeon - but you have to write the network.service and wpa_supplimant.conf

Once the RPI was connected I had to build bfgminer from git - and even then there is a minor issue.  
Seems bfgminer's -S auto will not detect the USB sticks.  You therefore have 2 options, use -S all which will make bfgminer open all usb's for mining and is not advisable.
Or, you can manually list all devices like so
Quote
-S /dev/ttyUSB0 -S /dev/ttyUSB1 -S /dev/ttyUSB2 -S /dev/ttyUSB3 -S /dev/ttyUSB4 -S /dev/ttyUSB5 -S /dev/ttyUSB6
After I built bfgminer I moved it to /opt/minepeon/bin/bfgminer so MinePeon's scripts will use it.

I then edited the service file and changed the command to start bfgminer to

Quote
sudo /opt/minepeon/bin/bfgminer -S /dev/ttyUSB0 -S /dev/ttyUSB1 -S /dev/ttyUSB2 -S /dev/ttyUSB3 -S /dev/ttyUSB4 -S /dev/ttyUSB5 -S /dev/ttyUSB6 -c /opt/minepeon/etc/miner.conf --icarus-options 115200:1:1-r
(note - experimenting a bit with the icarus-options.  Some people have reported using cgminer this way, I am not sure yet if it matters to bfgminer)

Finally, this code will switch MinePeon to bfgminer

Quote
sudo systemctl stop cgminer.service    # Stops cgminer
sudo systemctl disable cgminer.service # Stops cgminer from starting at boot
sudo systemctl enable bfgminer.service # Makes bfgminer start at boot
sudo systemctl start bfgminer.service  # Starts bfgminer

I feel I should note that these things run HOT.
I was hoping to use the 2 over-voltage ports on my hub to squeeze a little more power from these guys, but when they sit by themselves with no air flow they will burn the skin if touched.
Also hardware errors are slightly problematic.  I am not sure what is normal, but a couple of my seem to be incapable of doing anything except spit out errors.  (see pic)
Not sure if its the heat, the RPI, or the hub just yet.

If you found this info helpful feel free to help me out too 13vEmRoo8beAfdLc9ELw8GGAH3WTYgoEg4

Finally - here are the pics

i ordered this 10-port, 3.5A hub: http://www.newegg.ca/Product/Product.aspx?Item=N82E16817182257

should be good enough to power my 5 miners (~2.5A).

i've heard reports of people having success using Rosewill hubs with the Raspberry Pi, so I'll be giving that a try with MinePeon as well.

i've heard reports of people having success using Rosewill hubs with the Raspberry Pi, so I'll be giving that a try with MinePeon as well.

That's a 3.5A you've got there. and 2.0

I heard the 3.0 is better due to increase in amps per hub.
edit: Though I have heard some software has issues with 3.0 hubs.

However the 3.0 listed and proven Hub is 4A.
So at 2.5W ea. the 4amp gets you 8pcs Erupters.

The 3.5amp gets you 7pcs Erupters.
Not including powering any fans.

However IF the transformer powering the hub is external you could find a 4 or 5amp one and switch it out.

IF you buy a Hub at half the cost and power 5 Erupters and a fan while skipping every other port
it may aid in keeping heat down or need of a fan in certain circumstances.
Especially IF you have the Hub mounted on something skinny to aid air flow from underneath.
IF the Hub is on a completely flat surface (as most are) it does not pull cooler air from below
efficiently enough to cool them properly IMO. And the entire Hub gets warm.

This Hub has a switch to possibly Power 6 or 10 ports.
There may be "limiters" on each port.

I'm trying only to post known "in use proven" hardware etc. on the main page.
Let me know how it works out!

I started mining with my Erupter / Raspberry Pi yesterday.

I'm running the hard-float Raspbian image (2013-02-09-wheezy-raspbian) from raspberrypi.org on my pi.  I liked MinePeon but when I tried it there was no way to upgrade the system other than completely rewriting the SD card with a new image.  I had trouble getting my wifi working with the arch linux image from raspberrypi.org.

I'm mining on the rpi with cgminer v3.1.1.  I downloaded a tar of the tagged version from github (https://github.com/ckolivas/cgminer).  Build dependencies were installed with apt-get.  I had to set my LD_LIBRARY_PATH so that it could find the jansson library.  I'm using the following hardware-specific cgminer options:

  --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S /dev/ttyUSB0

I have this Manhattan hub (http://www.adafruit.com/products/961) which I would not recommend for Erupter mining due to the layout of the ports.  I'll be replacing it with the DLink DUB-H7 mentioned earlier in this thread.

why is the HW error so high on erupters?

What I have discovered so far is that some are expected and others are due to too much heat. I have also seen posts noting conflicts with certain software and USB3.0 Hubs. Last I saw is patches were being developed and by now may have already been completed.

Let me know what you find out.

I get about 1-1.5% HW errors.  I only have one erupter, so it isn't a sufficiently large data set.  I'm hanging the erupter with a usb extension cable in front of a box fan.

I am also seeing about 1% HW errors - and my units are no longer hot now that I have moved things around a bit.
I believe these numbers to probably be normal  Undecided

If it is, it must S/W controlled.  I've looked at the stick, I don't see any place place where you can adjust the voltage/current like on the blades.

I'm not sure if you'd be able to do it within cgminer, have you tried? Similar to how you can adjust GPU clocks, maybe the voltage of the stick can be changed.  Huh

I heard it regulated the W on board.

So IF say you plug in a 6.5v transformer into your usb hub it may just regulate it down to 5v.

I'd like to see it done though.
Wonder if it will blow anything on your computer through the USB connection to it though???

Did anyone figure out how to run it on a mac?

There is a mac only thread here somewhere. Try there.
Please let me know what you find out.

I was unable to build cgminer or bfgminer on OS X 10.6, so I couldn't even test it.

I am also seeing about 1% HW errors - and my units are no longer hot now that I have moved things around a bit.
I believe these numbers to probably be normal  Undecided

I switched to the DLink hub (D-Link DUB-H7) with the ARCTIC Breeze fan (~5mm above the erupter) and I'm seeing <0.1% HW errors.

I am using Windows 7 32-bit and CGMiner 3.1.1 with no special settings on Slushs Pool. My usb hub is an old hub i had from my Xbox 360 Rock Band kit. I picked up a desktop fan from Walmart.

To get Windows 7 to see my Block Erupter i downloaded the driver from here: http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx
I looked in device manager under Ports (COM & LPT)
I didnt install any of the things from the .zip, i just extracted the contents into a folder on my desktop. Then from my Block Erupters Properties i manually searched for the directory of the driver. It found the driver and installed it when i pointed to the extracted folder.

I made myself a .bat file in the cgminer folder. At the end, the "COM#" is whatever number the Block Erupter gets assigned in device manager -> Ports (Com & LPT). Mine happened to be COM3. Only one line in my .bat.
Quote
cgminer.exe --disable-gpu --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S COM3

I saved the .bat and made a shortcut to it to place on my desktop. I just run the .bat and my miner gets to work. Of course on first startup, i had to enter the address:port of the pool i am using, my worker name, and worker password.

Just about 1% Hardware Issues.

Heres some pictures.

I also have three more Block Erupters, a new USB hub, and a couple fans heading my way in the mail right now.

USB Hub: http://www.amazon.com/gp/product/B000KUQ8FG/ref=oh_details_o00_s00_i01

I found this in the USB hub reviews. "Comes with external power adapter. Output 5V, 2.6A, Energy Consumption 13W max."
I should be able to power my 4 Block Erupters with no problem.

I plan to get cgminer compiled on my Raspberry Pi Model B. Can anyone help a Linux noob compile cgminer 3.1.1 on a Raspberry Pi?

My order in the Europe group buy for 2x USB Block Erupter's arrived safely today here with me in the UK.

Thank you! - yxt (and Friedcat ofc).

I decided to test the device on my old Asus Eee 700 PC (laptop) which has a 2GB SSD HD - 800 Mhz CPU - 512 MB RAM - running Windows XP.

This is a special laptop - as in 2009 I used this very machine to generate 'a few extra Bitcoins' - Yes really!  Shocked  Cool

With it's 800 Mhz processor this laptop probably generated somewhere around 1000-ish Bitcoin's, which are now in full circulation ofc. It ran 24/7 for several months (2 of these laptops actually on/off), until 100's of new nodes arrived on the Bitcoin network and the difficulty level got to great.



Obviously I'm not running the 2x USB Block Erupter sticks 24/7 using this laptop...

My Alienware desktop has a USB 3.0 'charger' cable socket and I've also purchased an ORICO W8PH4 Series 'Super Speed USB 3.0 Hub' (4 port) and although it doesn't need a power cable I did need an AM/AF 1.5m USB 3.0 (blue) extension cable for it. Note that only 2 USB Block Erupter's can attach to this hub due to the direction and spacing of the ports, but it is a fully working hub. Also pictured is an USB 'Mini-Fan' JLK-002 which has an 'Ultra-low Power-wind Volume' (according to the box - lol), which was 'cheap as chips' on ebay and just the job. It really does have 'Power-wind', I had to stick it down with blue tack, I'd recommend it in fact! Grin

Interestingly enough plugging the USB Block Erupter into the Hub didn't load or recognize the drivers at first. However, plugging the stick into the PC's same USB port and then afterwards (reconnecting it) via the hub, it was recognized instantly! I suspect that this might be the case with most hubs!



A good cooling fan is essential and USB 3.0 charger (blue) Ports / Cables / Hubs (where possible) - as I've noticed much reduced HW errors when incorporating all of these factors.



With this 'High-Power' / good cooling set-up each USB Block Erupter has settled at around 334 to 335 Mh/s with cgminer 3.1.1 after several hours of operation.

I was a very early Bitcoin adopter - I sold over 12,500+ BTC before they reached just a few cents! I bought a slice of a rather famous Pizza!? and donated 500 BTC to the first Bitcoin Faucet. Got a bit lost along the way... logged out 2010... logged back in 2013... the rest is history? I did 'find' around 25 BTC (in various wallets and websites), which is better than none!

Thanks for the thread. I got my Erupter yesterday but I can't get the damn thing to work :/

Here's what I have tried so far :

Plugged directly into Thinkpad X60 laptop USB (should be enough power).
Plugged into a D-Link DUB-H7 (same as pictured in an earlier post that shows it working).
Plugged into a PlusCom U7PH-3A.

When I plug the Erupter in the green light flashes 4 times then stays on.

lsusb shows :
Bus 002 Device 009: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light

/dev/ttyUSB0 appears.

Ubuntu 13.04 with http://ck.kolivas.org/apps/cgminer/3.1/cgminer-3.1.1-x86_64-built.tar.bz2 (i read v3.2.0 doesn't work) I run :

./cgminer-nogpu -o http://eu-stratum.btcguild.com:3333 -u xxx -p xxx

tried these extra options too :

--icarus-options 115200:1:1 --icarus-timing short
--icarus-options 115200:1:1 --icarus-timing 3.0=10
-S /dev/ttyUSB0
-S all

Nothing gets detected and its "Waiting for USB hotplug devices" and just idle.

I tried bfgminer 3.0.2 too and that just CPU mines as it can't seem to find it either.

I also tried MinePeon on my RaspberryPi and get no results either.

Am I being dumb, have I missed something obvious or do I have a faulty Block Erupter ? Any ideas welcome Smiley

This is a fantastic piece of equipment for new comers as well, for people who are not familiar with mining Bitcoins, I have been suggesting these, because they are so simple to use.

Thanks for the quick reply!

No I haven't installed any drivers. I just tried to build the one you linked to but it fails.

Ubuntu 13.04 uses the 3.8.0-22 kernel which as far as I know already has the driver built in. /dev/ttyUSB0 appears so I guess this implies it does. Here's my syslog when i plug the device in :

sorry, have to ask - hub is connected to external supply/wall wart?

Otherwise, your built in driver may be icompatible

Yes. I will look further into the possibility that its a driver issue. My gut tell's me it isn't but I'm running out of ideas and suspect that perhaps the Erupter may be faulty :/

Thanks anyway Smiley

Using cgminer on windows 7

Drivers installed with zadig as described and can view in device manager

I set up a .bat file and I when I try to run it, it flashes on the screen and automatically closes. Says "-S unrecognized option" Any ideas why?  I unchecked "hide extensions for all file types" as instructed when creating a .bat file.

My text in the bat file reads as follows: (replacing user/pass with xxx/yyy)

C:\cgminer\cgminer-nogpu.exe -o http://rr.btcmp.com:8332 -u xxx -p yyy d --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM3

The pathway is correct.  Can anyone see any problems?  Only 1 miner plugged into usb port. Thanks!

What version of cgminer?
I've tried both 3.1.1 & 3.2.0
Same thing happens.  I wish I could take my *ish to someone's house.  You guys would probably fix it in 2 minutes.  Anyone live in Northern VA?

Okay, new problem.  I gave up on cgminer and thought I'd try bfgminer.  When I run it, I get this System Error:

"The program can't start because libcurl-4.dll is missing from your computer.  Try reinstalling the program to fix this problem."

How do I fix this?

I set up a .bat file and I when I try to run it, it flashes on the screen and automatically closes. Says "-S unrecognized option" Any ideas why?  I unchecked "hide extensions for all file types" as instructed when creating a .bat file.

My text in the bat file reads as follows: (replacing user/pass with xxx/yyy)

C:\cgminer\cgminer-nogpu.exe -o http://rr.btcmp.com:8332 -u xxx -p yyy d --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM3

The pathway is correct.  Can anyone see any problems?  Only 1 miner plugged into usb port. Thanks!

Try COM3 instead of //./COM3

Are you sure you are using capital S?

And set the directory.

So you should have this in your bat:
Quote
cd \cgminer
cgminer-nogpu.exe --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S COM3 -o http://rr.btcmp.com:8332 -u xxx -p yyy
pause
(pause optional)

Mine just started working Smiley Problem is I can't see what i did any different this time. It does mention here that you have to replug it in between trying different versions. I left it plugged in while i was trying different versions etc... Will post if I find out any more info that might be of use to others in the same situation.

I plan to get cgminer compiled on my Raspberry Pi Model B. Can anyone help a Linux noob compile cgminer 3.1.1 on a Raspberry Pi?
 Embarrassed

Which linux distribution are you running on your raspberry pi?
2013-05-25-wheezy-raspbian
http://www.raspberrypi.org/downloads

Its debian but made for the pi.

This page has a good overview of how to build cgminer:
http://techblog.sethleedy.name/?p=24276

1. Install the dependencies using apt-get
2. Download cgminer v3.1.1 from here: https://github.com/ckolivas/cgminer/tags
3. Unzip or untar it somewhere in your home directory.
4. cd into the cgminer directory
5. Run "./autogen.sh" since you downloaded the zip/tar from github
6. Run "./configure --enable-icarus" (icarus support is required for the erupter)
7. Run "make" to build cgminer
8. Run cgminer with the icarus options listed earlier in this thread and one -S /dev/ttyUSBX for each of your erupters, where X is the number of the unit starting from zero.

If you get errors in any of the autogen/configure/make steps, it's likely there is a missing dependency that needs to be installed with apt-get.

This is what I get.  Without the pause, the window closes.

In my experience with cgminer 3.1.1, it asked me for the pool information the first time i started it up and continues to use it whenever i close and re-open cgminer. If it doesnt ask, you can go into the [p]ool settings and add your pool yourself. You can check out my post on page two of this thread and see if what i did could help you at all. Im using windows 7 32 bit and cgminer as well.

Also, im sure you did this correctly but i gotta ask anyway, COM3 is the correct COM# for your erupter right?

Well for what it's worth, here are my results of building and testing cgminer 3.2.0 on a Raspberry Pi running MinePeon-2013-05-25 (all in all pretty straightforward). Please consider, as a test, I did all this as root which might not be the best choice if you want to "update" your Minepeon system with it later on.

Imagine I'm logged in through ssh, I did a system upgrade beforehand.
Code:
pacman -Syu

Then I got the sources from the repo and built cgminer (btw, you need at least "--enable-icarus" for the USB Block Erupter to be supported). It suggests a little different compile flags in the README, you might consider using those.
Code:
cd ~ ; mkdir src ; cd src
git clone https://github.com/ckolivas/cgminer.git
cd cgminer
CFLAGS="-g -W -Wall" ./autogen.sh --enable-bflsc --enable-icarus --enable-bitforce --enable-modminer --enable-ztex
make

This should compile cgminer without errors obviously. Don't forget to stop any mining tool that might be running.
Code:
systemctl stop cgminer
systemctl stop bfgminer

Optional but lets start cgminer in a screen window, always nice.
Code:
screen

Then I just ran cgminer without any special options.
Code:
cd ~/src/cgminer
./cgminer -o http://<poolurl>:<port> -u <workername> -p <workerpassword> (or to set difficulty if supported by pool i.e. "d=2")

It threw some "comms error" msgs but after a sec all miners showed up and started hashing.  Cool

Here are my stats with a diff of 1 at start and 2 hours later (2 Lancelots and 5 USB Erupter). I still have to investigate the exceptionally high HW errors on 2 of the USB Erupters (But I got them too using the "build-in" versions of cgminer and bfgminer when I started hashing with these babys).





(seems cgminer sometimes reports wrong speeds like on BLT 1 in the 2nd pic, but that is sporadic and it is correct again after a short while, well here at least)

So all in all cgminer performs pretty nicely on my Pi. Thanks to the devs for all the effort they put into it!

Here's my setup: https://bitcointalk.org/index.php?topic=195037.msg2388932#msg2388932

I can't run plain cgminer.  My computer gives a system error, "The program can't start because OpenCL.dll is missing from your computer.  Try reinstalling the program to fix the problem."

How do I reinstall that?  Reformat?

COM3 is what my devices menu call it.

This guy has some good intructions.

http://rdmsnippets.com/2013/05/29/setting-up-asicminer-block-erupters-on-windows-7/

I got mine up and running on a Windows 7 and a Windows XP machine.

Download the correct drivers from http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

I had problems letting Windows search for the driver on the XP machine. It found the wrong one. Under Devices in the Ports section it should say Silicon Labs CP210x USB to UART Bridge (COM3) 

Yours may have a different COM number. Mine was 3. It is important for the command line later on.

I was initially unsuccessful with CGminer 3.2.0 but it may have been my problem.

I backed down to cgminer 3.1.1. Created a short cut to cgminer-nogpu.exe.

The I edited the properties of the short cut so the Target  looks like this on the Windows 7 machine

C:\cgminer\cgminer-3.1.1-windows\cgminer-nogpu.exe -o  stratum.btcguild.com:3333 -u yourusername_2 -p 123 --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM3

And this on the Windows XP machine

"C:\cgminer\cgminer-3.1.1-windows\cgminer-nogpu.exe" -o  stratum.btcguild.com:3333 -u yourusername_3 -p 123 --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM3

Note the parenthesis on the XP command. I do not know if it is critcal but it defaults that way.

The name after -u is really the worker name for btcguild. Which in btcguild is yourusername_suffix. So I have two workers called yourusername_2 and yourusername_3. Some of the examples have periods instead of underscores and I don't think that works with btcguild. I have played with any other options. Both units are hashing around 334M. And btcguild does not care about passwords for the stratum servers so use "123"

Is it stable with that hub??

i am thinking of getting one....

Do you think it will handle all 10 connected? I also saw a 12 port version. Would it work?

Well hopefully the new version of cgminer (3.2.1) that has a significant bugfix for these devices will allow people to move to it instead of sticking to the old version.

Compiled it on my Pi and it looks like as if it does perform much better with lesser HW errors still on diff 1 (check my previous post). Also, no need for additional options just like with 3.2.0. Thanks ckolivas and kano for the fast cgminer updates. Here's an addition to my previous post to get my test build to 3.2.1. Stop cgminer and do this:

Code:
cd ~/src/cgminer
make clean
git pull
./autogen.sh
CFLAGS="-O2 -Wall -march=native" ./configure --enable-bflsc --enable-icarus --enable-bitforce --enable-modminer --enable-ztex
make

You can also add --enable-avalon Smiley
If you plug the avalon into the USB port of whatever you are mining with

LOL well the avalon itself is only a tplink 703 router and it averages ~20% CPU running an avalon, so the rpi should certainly be up to the task.

LUL... yeah, I saw the option but is it even possible to "circumvent" the hacked up tplink board they use (are the Avalon blades connected via USB)? But I too think a RPi should be more than sufficient, although Avalon added more RAM and stuff to the tplink board. I believe I even read that Bitmine.ch is planning to replace the tplink board with a RPi in their clones at a later time.

Oh yes, it's easy to take the lid off, pull off a jumper and plug your USB cable in where the Avalon's own FPGA controller plugs into it. I've run one off a PC for a while.

Just tried the 3.2.1 version on Windows 7. It seems to have the same problem I have seen in the past. It opens a command line window for about 200 milliseconds and then closes.

Short cut command used was C:\cgminer\cgminer3.2.1\cgminer-nogpu.exe -o  stratum.btcguild.com:3333 -u XXXXXX_2 -p 123 --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM3

This command works well in version 3.1.1. It also does not work in 3.2.0

I'm happily hashing with 3.1.1

New version does not take -S parameter all, and will also not need icarus options or icarus timing set since it knows the devices, so get rid of "--icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM3"

https://www.dropbox.com/s/fpxc6q94gqix9zl/RPi-CGMiner-1Erupter-1Hour.png

I see <1% errors usually, with peaks around 1%.  I saw >1% before I found a good cooling solution.

How hot is your erupter getting?  Can you hold your finger on the heat shield?

I see <1% errors usually, with peaks around 1%.  I saw >1% before I found a good cooling solution.

How hot is your erupter getting?  Can you hold your finger on the heat shield?



I think these puppies will overclock fine with an innovative cooling solution.

From what I can tell, we'll need some type of software interface to make overclocking possible. 
I believe this was previously accomplished with GPUs through the use of OpenCL.  So we'd need info/etc from ASICMiner on how/if this is possible.

ck or kano can likely clarify.

IMO- There needs to be an overclocking incentive to the Erupter...
Could you ask them?

I'm having trouble getting one of these to work... I'm using cgminer on linux. I'm probably missing something obvious, so any help is appreciated.

cgminer seems to detect it because I can get this (cgminer v. 3.2.0):
Quote
sudo ./cgminer -n

But then when I run cgminer....

Pretty sure I'm just being an idiot and missing something obvious, but any help would be appreciated.

What you're missing is that support for this device was broken in 3.2.0... try 3.2.1 or roll back to 3.1.1

No possible because the oscillator for the USB is a fixed frequency one. The voltage is also fixed at the lowest possible for the current frequency to match the 500mA spec of USB ports.

My Mother Board has 6 USB ports on the back.  It's an MSI 870-G45.

Is it safe to plug in 6 USB Block Erupters into it?  I don't see anything in the manual as to what the total power/current draw is.

So far it's steady around 334.2Mh/s.  I finally got 99 of them working with CGMiner 3.1.1 this evening on a Win7 laptop.

Had a lot of trouble with 3.2.1 crashing on Win7 after about 6 detections, so I decided to roll it back and try my luck with 3.1.1.  Missed the hotplug aspect of 3.2.1, but being able to specify each com## worked out well.   Running 10 Anker hubs with 9 usb miners with arctic fans, and 1 Anker hub without the fan.  For some reason one of the ports isn't working on the 11th, so 100 has been elusive.  

Ran a copy of CGMiner for each Anker hub and hopefully this will stay up.  With BitMinter, I had to restart a couple of workers every so often, so CGMiner has been great.

Earlier in this thread, Rounder gave me instructions on how to install and configure cgminer 3.1.1 in linux. I updated them a little bit to get the newest cgminer which plays much more nicely with the block erupter.

This page has a good overview of how to build cgminer:
http://techblog.sethleedy.name/?p=24276

1. Install the dependencies using apt-get
2. clone git://github.com/ckolivas/cgminer.git
4. cd cgminer
5. ./autogen.sh
6. ./configure --enable-icarus
7. make
8. sudo make install
9. sudo cgminer

If you get errors in any of the autogen/configure/make steps, it's likely there is a missing dependency that needs to be installed with apt-get.

(If anyone sees a wrong command or anything, feel free to quote and fix it. Im still kinda new to linux.)

That's .5 Amp.  So you think that can be delivered by all 6 ports?  I do have some USB hubs on the way but the Block Erupters will probably be here first.

How are your error rates with the Arctic fan? I was running one on an Anker as well, but it seemed like it wasn't big enough to get airflow to the USB ports at the edges. On the other hand, right now I have an 8" desk fan pointed at the hub and miners, and I'm seeing about 1% errors, so I'm not convinced that that's much better than the Arctic.

Well hopefully the new version of cgminer (3.2.1) that has a significant bugfix for these devices will allow people to move to it instead of sticking to the old version.
Compiled it on my Pi and it looks like as if it does perform much better with lesser HW errors still on diff 1 (check my previous post). Also, no need for additional options just like with 3.2.0. Thanks ckolivas and kano for the fast cgminer updates. Here's an addition to my previous post to get my test build to 3.2.1. Stop cgminer and do this:

Code:
cd ~/src/cgminer
make clean
git pull
./autogen.sh
CFLAGS="-O2 -Wall -march=native" ./configure --enable-bflsc --enable-icarus --enable-bitforce --enable-modminer --enable-ztex
make


What does this do?
Quote
CFLAGS="-O2 -Wall -march=native"
CFLAGS is used to pass arguments to the compiler. In this case "-O2" for optimization (enables various optimization flags) of the generated code, "-Wall" enables various warning flags and "-march=" selects for which processor architecture you'd like to compile, "native" determines the processor type of the compiling machine.

You can find most flags explained i.e. here.

Currently getting about 1%+ with the Arctics.  While the ones on the edge feel a bit warmer, the error rate is actually on par with the interior ones so I've been thinking about getting a desk fan to increase the overall airflow.

Interesting, maybe I should switch back to an Arctic. I get a little under 1% with a desk fan, but not much under 1%. The big problem with my desk fan, at least, is that it's just wide enough to cover all my Erupters, but there's a big airflow dead spot in the middle where the fan's axle is. So the BE in the center of the hub runs slightly hotter and has a slightly higher error rate than the rest.

I have a couple of these on order, maybe they'll work better: http://amzn.com/B00080G0BK

don't mean to re-ask a question, but im holding 330 mh/s in my cgminer window, but when I check my pool stats page (coinotron.com) my reported hash rate is much lower at times and also much higher, ive seen it anywhere from 100kh to 500 kh/s

just wondering if that normal and reason behind it. thks

Yep, that's the plan.  I'm just worried about stressing or frying the M/B or having the current on the hairy edge and start having flaky problems.  Hopefully I'll find out tomorrow night.

You're probably going to be better off with the Thermaltakes on order, the arctic fans aren't cutting it right now.  After more than 24 hours the HW errors are piling up, it's jumped to over 10% error rates.  Sad Thanks for the link, might just get a couple of thermaltakes as well.

"snipped"

It could be the hub itself.
On main page info of lesser error D-Link hub.
Also calculate how many watts you are using to not over draw from hub.
don't put hub on flat surface as heat builds up.
Put hub low in altitude as it's a few degrees cooler on the floor.

It's true the hubs can make all of the difference, I had been running 10-port Manhattan hubs with many problems it powering off intermittently.  Decided to go all Ankers which have been rather stable in comparison.  Appreciate the suggestion on the draw and placement, will give it a try!

don't mean to re-ask a question, but im holding 330 mh/s in my cgminer window, but when I check my pool stats page (coinotron.com) my reported hash rate is much lower at times and also much higher, ive seen it anywhere from 100kh to 500 kh/s

just wondering if that normal and reason behind it. thks


A pool can only calculate your hashrate through your actually submitted shares/time.
So it could vary quite a bit at times... should be normal as long as your payout is what you'd expect (or accepted shares).

No possible because the oscillator for the USB is a fixed frequency one. The voltage is also fixed at the lowest possible for the current frequency to match the 500mA spec of USB ports.

Ah - thanks for that insight.

""Generation 1:
Block Eruptor. 130nm with 6-8J/GH. Each chip's rated frequency is 336MHz at 1.05V. It translates to 336MH/s because it does one hash per cycle. The chips work stable and well at 392MH/s at 1.15V. Further overclocking needs proper handling of heat and power supply.""

I had one of the arctic fans running but it was too loud (my HTPC is passively cooled, so completely silent - this fan is not!).  Anyway, I let them run without the fan and they've been doing fine for days now (famous last words).  No change in performance.

What speeds are you guys holding? Mine is at 330.5Mh/s. Been going a since Wednesday. About 3.5HW errors an hour.

So far it's steady around 334.2Mh/s.  I finally got 99 of them working with CGMiner 3.1.1 this evening on a Win7 laptop.

Had a lot of trouble with 3.2.1 crashing on Win7 after about 6 detections, so I decided to roll it back and try my luck with 3.1.1.  Missed the hotplug aspect of 3.2.1, but being able to specify each com## worked out well.   Running 10 Anker hubs with 9 usb miners with arctic fans, and 1 Anker hub without the fan.  For some reason one of the ports isn't working on the 11th, so 100 has been elusive.  

Ran a copy of CGMiner for each Anker hub and hopefully this will stay up.  With BitMinter, I had to restart a couple of workers every so often, so CGMiner has been great.

A big thanks to MikeMike for starting this thread and to everyone who has posted.


How are your error rates with the Arctic fan? I was running one on an Anker as well, but it seemed like it wasn't big enough to get airflow to the USB ports at the edges. On the other hand, right now I have an 8" desk fan pointed at the hub and miners, and I'm seeing about 1% errors, so I'm not convinced that that's much better than the Arctic.

Currently getting about 1%+ with the Arctics.  While the ones on the edge feel a bit warmer, the error rate is actually on par with the interior ones so I've been thinking about getting a desk fan to increase the overall airflow.

Interesting, maybe I should switch back to an Arctic. I get a little under 1% with a desk fan, but not much under 1%. The big problem with my desk fan, at least, is that it's just wide enough to cover all my Erupters, but there's a big airflow dead spot in the middle where the fan's axle is. So the BE in the center of the hub runs slightly hotter and has a slightly higher error rate than the rest.

I have a couple of these on order, maybe they'll work better: http://amzn.com/B00080G0BK

You're probably going to be better off with the Thermaltakes on order, the arctic fans aren't cutting it right now.  After more than 24 hours the HW errors are piling up, it's jumped to over 10% error rates.  Sad Thanks for the link, might just get a couple of thermaltakes as well.  

Thanks for the info. Hopefully the Thermaltakes will arrive today. I'll report back on how effective they are.

"snipped"

It could be the hub itself.
On main page info of lesser error D-Link hub.
Also calculate how many watts you are using to not over draw from hub.
don't put hub on flat surface as heat builds up.
Put hub low in altitude as it's a few degrees cooler on the floor.
Just a word from the blind...
  Wink


It's true the hubs can make all of the difference, I had been running 10-port Manhattan hubs with many problems it powering off intermittently.  Decided to go all Ankers which have been rather stable in comparison.  Appreciate the suggestion on the draw and placement, will give it a try!     
Even the Anker's have issues as someone posted about an issue of two USB ports of the 10 on one hub always had issues.
So on that particular hub they ran two less Erupters. I'm nearly certain it was an anker.

That's .5 Amp.  So you think that can be delivered by all 6 ports?  I do have some USB hubs on the way but the Block Erupters will probably be here first.
Thanks,
Sam

y'know, i'm really not sure. add them one at a time until things stop working Wink

Yep, that's the plan.  I'm just worried about stressing or frying the M/B or having the current on the hairy edge and start having flaky problems.  Hopefully I'll find out tomorrow night.
Thanks,
Sam

Well, I could only fit 4 Erupters into the M/B six USB ports.  But they seem to be working just fine.  So I doubt there would be any problems powering them.

I am using CGMiner 3.2.1 and got them mining without a hitch, so far anyway.  I was afraid I would have some problems like everyone seems to be having but the install and setup could not have been easier.

I received the Thermaltakes earlier today and they've been running for about 8 hours now. I can report that, so far, they cool at least as well as the desk fan; I'm slightly under 1% errors overall. The two of them side by side also cover the length of the Anker hub a bit better, without much of a dead airflow spot in the middle.

They're a bit noisy at full speed, but they draw a *lot* less power than the desk fan, so that seems like a fair trade-off to me.

I'm using the 120mm TT fan @ ~80%, surprisingly quiet - found no benefit to running @ full speed.

Nice! I'll have to try turning these down a bit and see if it makes any difference to error rates.

On the overclock issue - what software or commands would you use to change the voltage on these??

On the increased rate of errors over time issue - maybe a periodic programmed cooling-off period would be overall beneficial?

I had the same thought. Running the fan off of a separate hub doesn't seem to help in my setup though. 
Not sure if fan proximity could play a role (motor EMF?). 

Need to establish a little testing protocol here.


On the overclock issue - what software or commands would you use to change the voltage on these??
friedcat (he of ASICMiner) stated earlier in this thread that overclocking was not possible due to the chip's timing being dependent on USB fixed clock frequency & voltage.  One could speculate that one would need to get the chip running off of an external variable voltage and/or clock - but one would certainly risk bricking their erupter with such an experiment  Tongue

Also might want to try putting the ones with higher errors in slot of ones with lower errors and skip every other one for heat related and POWER related issues...

No don't..... it is a STUPID idea......

1. Peltiers consume a MASSIVE amount of power for the cooling you get.
2. There is a significant cooling down time.
3. They fail silently.
4. You STILL need a fan....

Hmm - after a few hours of testing with the added heatsink, I'm seeing no significant reduction in error rate.
(This was w/ a 120mm ThermalTake fan, btw)

I'm guessing we might see some benefit from replacing the large stock heatsink w one that has a greater surface area (such as the one seen on the emerald prototypes) - but again, just a guess.  No doubt that friedcat did plenty of testing before finalizing this design - always fun to experiment tho.

As cool looking as these are, and as much as I want to get into ASIC, it looks like these will probably never earn you your 2BTC.  At current difficulty, it would take something like 240 days to recover your investment, but we all know difficulty is shooting through the roof.  Considering the basic chip is around $10 in bulk, the whole shebang should be going for around $50.  I know you didn't set the price Canary, but that's my .02 BTC.

I take it error rate % is determined by HW/A * 100 (cgminer)? Also mine is holding at 330MHs. Anyone getting better? No fans, plugged into my desktop.

Mine are holding at 335.5MHash/s. Error rate about 4.5/m but this is without any cooling.

Hmm - after a few hours of testing with the added heatsink, I'm seeing no significant reduction in error rate.
(This was w/ a 120mm ThermalTake fan, btw)

I'm guessing we might see some benefit from replacing the large stock heatsink w one that has a greater surface area (such as the one seen on the emerald prototypes) - but again, just a guess.  No doubt that friedcat did plenty of testing before finalizing this design - always fun to experiment tho.


I do think the Emerald type heat sinks protrude so much they heat up the Erupter next to it in the Hub.
Hub spacings are too tight.

Maybe it would help to have a cross piece added to the heatsink that hangs over the sides like a telephone pole's crosspiece.

I suspect that adding a heat-sink on the 'back' of the chip is not going to achieve much..., the thermal resistance is too high.

What is the temp on the inductor next to the chip and the DC/DC control chip?

Also looking at the board & it's PSU... it could do with a couple of tants. NOT ecaps...

also a bit surprised that the 'crypto' chip does not appear to be 'decoupled'...


But first point would be the temp on the inductor....

Ironically, I started playing around with the infrared temp gun yesterday and the ambient temp of the room seems to be the biggest factor. In the afternoon, the highest temp was ~120F. This morning it is ~110F. The inductor(along with the support chips) is about 5 degrees lower. I'm waiting on another Anker hub and I have an extra one plugged straight into a PC port vertically and it has a spot near the LED in the ~135F range. But the same area on the 9 in the hub is fine.

I used cgminer 3.2.1 to connect to btcguild, but I get this error:

It tells you why exactly there. You need to install a windows usb driver. As the docs say, you DO NOT USE THE FTDI DRIVER that other software uses, when using cgminer. You'll see exact instructions for it spelt out in the ASIC-README included with cgminer.

I can confirm that with proper cooling, the HW error rate of the Block Eruptor drops to a fraction of the rate without cooling. The Arctic Breeze USB fan is ideal for this, although you may have trouble fitting it into your USB hub. I used a separate USB power supply.

Their fans were not doing the trick so....their idea did as errors rate dropped after mod.

Actually, scratch what I said. I haven't run the rig long enough to see if the cooling affects the HW error rate this much. Watch this space.

Actually, like I said previously, I have 9 with the fan in a hub and one just plugged straight into the PC and while that one has one of the higher error rates, it is not the worst!  I also tried throwing one in the fridge and then freezer for 20 mins and trying it and hashrate & error rate was the same as the others. Also, about the theory that they are too close - one of the worst error rate ones is right next to one of the best ones. So, I'm getting the impression that it's pretty random how each one performs, just like lemons come off car assembly lines and I can tell you from my job, that quality of workmanship is really the BIGGEST factor in how a product performs. Obviously, design and quality of materials are also huge factors.

In that case I'm getting about 0.8% error with cooling. Without cooling I'm getting 1.0%

However, without cooling, my hashrate starts to drop after a couple of days. The fan seems to fix this.

Considing it's the size of a thumb, you are being a bit picky.  :-D    GPUs mining BTC may have low error rates, but mining scrypt all out... anything less than 3-5% is acceptable, and normal. BTC is intensity 8-11(depending on GPU model) and scrypt is usually 13+

I was just talking about that, I am not sure ROI will be reached inside of 365 days sadly. There is however a growing market on the auction sites which could be profitable. I have a fan mounted on my rack which moves air across all the mining hardware, I had a usb fan but it was causing hardware errors on a couple of the AMUs, I suspect the fan is a power hog and the DLink did not have it to spare. I have been running for 6+ Hours with NO issues  Grin

What's your HW error % rate? Divide HW by A to get it. Mine is 0.8%.

EDIT: You might need to calculate it individually because you have other hardware besides the AMUs.

I've got the same/similar setup(hub/pi/bfgminer).  when i plugged in 7 sticks i had 2 give problems.  one was puking errors and the other refused to hash.

i unplugged 1 stick and started a fan blowing across the 6 USB sticks.  the 1 stick which was previously giving >10% hw errors started hashing normally.
the 6 sticks even after not clearing errors are now averaging ~1% hw errs over 30 hours now.  the actual rate should be much lower once i restart and clear the counters.  i measured the sticks at 140 degrees F without the fan.  with fan they're comfortable to the touch.

How much current does your power adapter deliver? The USB eruptors require 500mA each. The DUB-H7 can deliver 3A, which is 5 eruptors and 1 fan, or 6 eruptors.

So I have 2 USB ASIC Erupters on a DLink H7 connected to my pi (using latest wheezy hard-float build). Got cgminer 3.2.2 installed and it's mining. However, 1 is averaging at 60 MH/s and the other one is averaging 116 MH/s. I have no clue why it's going so slow.

I using these current configurations
http://learn.adafruit.com/piminer-raspberry-pi-bitcoin-miner/configure-settings


Now when I go a plug the hub into my PC running Windows 7 and I run cgminer with same configs, I'm getting the desired average of 333 MH/s per stick.

Since I'm getting my desired hashrate on my windows machine it's making me think that it's a software problem. I though of it maybe being a hardware problem concerning power, but people are posting this hub works fine with 7 usb erupter's connected to them. I only have 2 connected at the moment.

I'm running out of ideas. Anyone have an idea of what it could be?

So the way I read that is

HW/(A*Diff)

which is
115/(200*128) = 0.0044921875 = .449%

Seems pretty good to me.

With this .bat CGminer opens and Runs all three gpus 7950s, as well as recognizes my block erupter.  I have the BE in a USB 3.0 slot and its mining consistently at 333mh/s~.

Also, as you can see by my bat config I did not need to include and special settings for the Block Erupter.  I just installed the two drivers, restarted my computer and CGminer 3.2.2 recognized the card.

As far as hardware errors, Im literally seeing like 20 per 1000 shares accepted. give or take. so not so bad.

Increasing difficulty in stratum increases hw error % across the board for me.

Didn't mean to imply you didn't understand, sorry.

What is your "slight" increased rate? from what to what?

Calculating Diff1 shares won't be exact so there will be slop in how many diff1 you would have submitted if you weren't using higher difficulty.

Those are a bit dear! I'd be going for these cause copper doesn't transfer heat to the air very well either.

You could just stick a load to the top 'heatsink' side if they dont fit on the little chips on the other!

Well of course it won't work.

ASIC stands for Application-Specific Integrated Circuit -- it's hard wired to do only one thing: mine bitcoins.

It can't do other cryptocurrencies (except namecoins which use the same result at Bitminter).

49 Erupters … theoretically, yes should work as the bus should max out @ 127 devices.
Need an example of someone using that many devices on a single RPi before we know for sure.

Well your diagram poses a new question with me.

Is it better to configure the USB Hubs in a Star Topology as you are doing or to Daisy Chain them in a type of Bus Topology?

I am connecting mine in a Bus Topology and never really put much thought into doing a Star.

A Star topology offers a more direct route so that would be my first choice pending testing.  Why not spend a little extra for two Pi units for less chance on a single failure causing problems?  (both the primary usb hub and the pi)

I'm using 7 port Rosewill hubs which have 5 Powered ports and 2 unpowered which, I believe, have their own separate controller for the purpose of daisy chaining, or so I thought.

Are all 7 of the Dlink ports in Alexrossi's diagram powered?

I have been running cgminer version 3.3.0 on a raspberry pi/D-link 7port HUB with a single usb erupter for days without any problems.

However, when I put more than one usb erupter into the hub I can barely get one or two shares before all the leds light up on all erupters and they stop hashing.

Wondering if anyone else has seen this problem and if it might be due to version 3.3.0, since there are posts in this thread of folks running multiple usb erupters with a raspberry pi.
Thanks.

It can be done, here is another screenshot for you;-



That's 1 x BFL Jalapeño (VERY old version) running alongside 9 Block Eruptors.  I have heard that there has been stability problems with the AMU driver (even the cgminer authors say that there might be) but I have always been curious as to why MinePeon does not appear to be affected.

Is there any chance I could convince you to download MinePeon and see if it makes a difference?

Perhaps something Arch Linux has over Raspbian?

I had to roll back to cgminer 3.1.1 to get multiple eruptors playing nice.

fwiw - I plan on trying MinePeon asap - nice work.
