We are actually just doing system maintenance and preparing to relaunch on Monday.  Phew, i was worried for a second there. |

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: 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? CFLAGS="-O2 -Wall -march=native" |

This page has a good overview of how to build cgminer: http://techblog.sethleedy.name/?p=242761. Install the dependencies using apt-get 2. Download cgminer v3.1.1 from here: https://github.com/ckolivas/cgminer/tags3. 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. HTH SUCCESS! Thank you so much!  I have been running my Raspberry Pi with cgminer 3.1.1 and just one block erupter. Does the pi give the erupters high hardware failures for everyone? https://www.dropbox.com/s/fpxc6q94gqix9zl/RPi-CGMiner-1Erupter-1Hour.pngI 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.
Thanks!
Install the OpenCL SDK included w AMD's Catalyst drivers. (It's an open source platform for GPU hardware) Yes. This. I got mine from here. http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/ |

Rounder, Thank you so much! Ill have to try this out tonight after work. joae1975, Try running cgminer.exe instead of the cgminer-nogpu.exe with a .bat that just has this one line. cgminer.exe --disable-gpu --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S COM3 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? |

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?  Which linux distribution are you running on your raspberry pi? 2013-05-25-wheezy-raspbian http://www.raspberrypi.org/downloadsIts debian but made for the pi. |

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.aspxI 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. 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. https://www.dropbox.com/s/vqbplyi5s2ghk42/Block%20Erupter%20Win7%2032bit.png?v=0mcnshttps://www.dropbox.com/s/189fmeosipf7jlj/IMG_20130509_013839_951.jpg?v=0mcnshttps://www.dropbox.com/s/51rcalcnq5ogih6/IMG_20130605_155107_922.jpg?v=0mcns--------- I also have three more Block Erupters, a new USB hub, and a couple fans heading my way in the mail right now. Fans: http://www.amazon.com/Coolerguys-Dual-80mm-Cooling-Fans/dp/B002NVC1DS/USB Hub: http://www.amazon.com/gp/product/B000KUQ8FG/ref=oh_details_o00_s00_i01I 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? I want to thank doubledave for helping me out with everything. He introduced me to bitcoins and has been helping me out with anything pertaining to them since. Hes the best, around! |

Just to check, on Linux, is 3.2.0 working fine? (Using 1 Ztex, 2 BFL FPGA and a bunch of ASICMINER USB sticks)
Or should I stick on the previous version?
If it initialises the AMU (Asicminer USB Block Erupters) correctly, then yes go with it. If not, on linux, you simply need to unplug and re-plug in your USB devices before you start 3.1.1 (and use --icarus-timing 3.0=100 --icarus-options 115200:1:1 + the -S device selections) Is there a way to get this Block Erupter working with the litecoin mining -scrypt option? |

So is this Block Erupter capable of litecoin mining with cgminer?

A question for those of you running these block erupters on their raspberry pi:
Where in /dev/ do you find these? Is it /dev/ttyUSB1 or /dev/bus/usb/ or somewhere like that? Does some driver need to be installed for them to show up? I plan on trying to use bfgminer first with the -S all option.
They will show up as /dev/ttyUSBx. No need to install a driver, the USB2Serial driver is preinstalled on a rpi.  I dont know if it would make a difference but do you have any recommendations for a USB hub that i could use with a raspberry pi? One that can power at least four of these block erupters. Please and thank you! |

Canary,
Updating the status of verified messages in your original post like you have done in group 1 and 2 and now in group 4 serves two purposes. Many of us see that post long before we check PM. Once verified we can also stop worrying about it. I had trouble sending a verified message intially because I was a newbie. I'm certain I could do it flawlessly now. However, I don't want to send you a second one lest I just confuse the issue. So I am waiting for you to update the original post for group 3. I know you have a day job. Frankly I don't know how you can handle this load. Keep it up. Thanks.
Well said! I had so much trouble just not understanding that you could send a verified message from an address without sending a payment...So it jailed me for a week! You guys are right, this whole send message with payment as opposed to just sign any message with an address and send the text is confusing everyone... that's got to be it, I can totally see how it's confusing... --- i'm going to be incognito for 1 hr, need to finish entering shipping info into insurance system... got 1 hr till cutoff The updated OP of this thread shows most of us didn't get the signed message right. I have resent you a signed message, the short version, per your instructions in the group 4 thread https://bitcointalk.org/index.php?topic=222960.msg2343943#msg2343943Here's hoping you can get group 3's orders out today. PS - when do you sleep? Ive done the same. The first pm i sent you wasnt formatted correctly, but now it should be an easy copy and paste to varify. |

Received and tested. It works, thank you arklan!

MikeMike, please try to follow my instructions here... I would like you to sign this message with each of the sending addresses (so you will have 2 PMs for me): Quote: your name street address city, state zip end Quote now wrap it around: ----------start--------- -----end--------------- and PM it to me with the generated signature.... that's it. I don't want a poem, I just want those 3 simple lines without any line breaks or new lines.... Can you please do what's in my example so that I can verify your message? 3 lines please! Ill have to remember that format. Sorry if my pm was annoying to try and varify. |

I'm purchased 20 of them.
The plan is to hook them to a Raspberry Pi. Do you think it can handle communicating with 20 units?
Powering them seems to be another issue. Could a socket be soldered to the board to power them, instead relying on the power from a powered hub?
Wow thats one hell of an experiment. I plan to use one with my RPi on a powered hub.. but twenty. Im not sure man haha. |

I was just saying that it is kinda upsetting that were ready but cant get them just yet is all. I never really thought i would make my full btc back and its just unfortunate that the difficulty is skyrocketing for whatever reason. I just want to get my hands on this usb miner since its gonna be my first real reason to start mining again. Toying around on mtgox is too stressful so i wanna get back into the mining game. Im excited! haha. Oh, and i still want my unit even if it takes a little more time!
arklan and John, you guys have been amazing and part of the most positive experiences ive had with bitcoin. Wish i could say the same about some other mining hardware dealers.
; D

Will this order be the first batch to go through, or was there a group buy that already went 300+ before us ?
Idk but its starting to look like by the time we get these units difficulty will be between 13 and 15 million. Good bye roi.  How upsetting.. :' ( |
