Topic: Trouble setting up USB Block Erupters with cgminer (Read 4333 times)
Working perfectly, thanks!
This "--usb ICA:1" I assume is some kind of system name assigned to the block erupter. Where do I find it to?
Thanks for your help!

It's under the Advanced USB Options in the readme.
"--usb" is self explanatory
"ICA" means Icarus device since the block erupters use that driver
":1" means to use one Icarus device, it doesn't matter which one.

PS - Also would like to know the correct syntax for assigning each USB Block Erupter to a separate worker.
Once you have the direct USB working you run two instances of CGMiner
cgminer-nogpu.exe --usb ICA:1 -o mint.bitminter.com:8332 -u username_workername01 -p password
and
cgminer-nogpu.exe --usb ICA:1 -o mint.bitminter.com:8332 -u username_workername02 -p password
This will run one Block Erupter in each instance to two different worker names. Don't know why you would want to run two workers on one pool. I run three instances with the same number of BE's for three different pools. That way I can compare performance between different pools easily. Also helps ameliorate variance.
Also using port 8332 implies your using getwork protocol. I would strongly recommend that you use the stratum protocol.
The -S and --icarus option's is ONLY for CGMiner 3.1.1.
The later versions use direct USB. So follow the instructions with the ASIC Readme included with the CGMiner download.
The problem with these web sites are that they are rarely up to date. The readme's with the software is always up to date.

I just got my first two USB block erupters and I'm trying to configure them in cgminer. I'm following the instructions here: http://bitcoinrigs.org/mining-resource/how-to-setup-asic-block-erupter/
I put the following command into the target of a desktop shortcut:
C:\cgminer\cgminer-nogpu.exe -o mint.bitminter.com:8332 -u username_workername -p password --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM3 -S //./COM5
And when I double click it, the command prompt just opens and closes again. So I open the command prompt directly, running as administrator, type in the same command and get the following error message:
[2013-09-08 18:17:23] cgminer-nogpu.exe: -S: unrecognized option
What gives?
