Topic: USB ASIC ERUPTER - Setup & Config. BCG Miner, cgminer & Hubs "Oh Pi"! - page 16. (Read 156908 times)

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?

Stands for "dont' know"   jk
No clue, took it out and no change.

hmm - what is that "d" for?

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?

What version of cgminer?

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!

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


I'm open to any other suggestions from other users ?

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

Otherwise, your built in driver may be icompatible

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 :

When I try and communicate directly with "screen /dev/ttyUSB0 115200" I get not output. Never tried this before so not sure if that means anything.

I would like to get this running on Linux (eventually my Raspberry Pi) and I don't have Windows so I'm unable to try any Windows programs / guides.

you've installed the driver?

(not sure if that was inferred anywhere in your post)


Also - a nice guide for win7 users is here:
http://rdmsnippets.com/tag/install-block-erupter-on-windows-7/

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 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

Its debian but made for the pi.

Which linux distribution are you running on your raspberry pi?

Awesome! Thanks for your Contribution. I hope you find what you need.

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.

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.

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_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?
 

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!

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