USB ASIC ERUPTER - Setup & Config. BCG Miner, cgminer & Hubs "Oh Pi"!

[ashpooler]

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
If you plug the avalon into the USB port of whatever you are mining with
Would be interesting to see if an RPi could handle mining on an avalon

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.

Heh, interesting (obviously I never had an Avalon in my hands or did a lot of research about 'em), very good to know. Thanks for sharing ckolivas.

Hi,

I have problem with usb erupter,
when I write command in raspberry : sudo modprobe cp210x vendor=0x10c4 product=0xea60
I get error :  ERROR: could not insert 'cp210x': Invalid argument


what the problem is ?


thanks for feedback

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

2.) Download/install Macminer 10.7
http://fabulouspanda.co.uk/macminer/downloads/MacMiner.app-10.7-1.1.2.zip
place macminer in applications folder

3.) Open terminal type: [edit details]

Code:

/Applications/MacMiner.app/Contents/Resources/bfgminer/bin/bfgminer -o [pool url] -u [username] -p [password] -S /dev/cu.SLAB_USBtoUART

4.) Press enter

Mining bitcoins with USB Block Eruptors bitches!

Done in minutes as opposed to all the BS I had to go through with my stupid pc.  Done and done!

edit:  Please note, developer has made changes since I made this post.

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"

What does this do?

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

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):

sudo ./cgminer -n

 CL Platform 0 vendor: Advanced Micro Devices, Inc.                   
 CL Platform 0 name: AMD Accelerated Parallel Processing                   
 CL Platform 0 version: OpenCL 1.2 AMD-APP (1016.4)                   
 Platform 0 devices: 3                   
    0   Tahiti                   
    1   Tahiti                   
    2   Tahiti                   
 3 GPU devices max detected

.USB dev 0: Bus 4 Device 6 ID: 10c4:ea60
  Manufacturer: 'Silicon Labs'

But then when I run cgminer....

sudo ./cgminer --disable-gpu -o eligius.sw -u xxx -p xxx

 Started cgminer 3.2.0
  No devices detected!
  Waiting for USB hotplug devices or press q to quit

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

Thank you! Its working in 3.2.1

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