Title: USB Block erupter
Post by: JBT on September 03, 2013, 05:53:36 PM
my friend gave me his usb block erupters, i install the drivers and they show up as comm devices. how do i use guiminer with them as bfgminer just uses one pool for them all.

can someone at least point me in the right direction

guiminer doesn't seem to support USB block erupters. See topic: https://bitcointalk.org/index.php?topic=3878.0

cgminer seems to be supported though (see https://bitcointalk.org/index.php?topic=220450.msg2321308#msg2321308), so you can mine on multiple pools with that.

thanks going to lookl. i use bfgminer with a few shortcuts bit instead of using -S all  i used -S com8  and the other shortcut -S com9.   althou com10 and com 11 doesnt seem work.....   with -S all only uses one worker....messy

ed..... \\.\com10 works now got all miners in seperate windows.....not nice but hell it works

I have seen where someone use -S erupter:all instead of -S all, dont know if that worked in bfgminer.  Also, you have to make sure you have the icarus options configured right, --icarus-options 115200:1:1 --icarus-timing 3.0=100"

Also, be aware that for many setups, cgminer 3.1.1 works best with Erupters.

Using the later CGMiner's with direct USB makes it really easy to run multiple instances with however many AMU's you want in each instance.

I use the command line --usb ICA:5 in each instance and have 5 devices pointed at multiple pools.  Makes it really easy to assess pool performance.

really? it works like that? what if there is one gpu, will they fight over it? i was wondering what i was going to do when there were too many AMUs to fit in the bigest window i can make.

Yep, just like that.

I retired my GPU's so I use the cgminer-nogpu.exe.

So if you want to run one instance of cgmner.exe for your GPU's only use --usb ICA:0 and it won't use any AMU's.  Then run a separate instance with cgminer-nogpu.exe for all your AMU's, or any number of them you wish.

It's covered in the readme under "Advanced USB options:".

i suppose that i could run one regular instance and one no gpu instance.

Yep, or use -G to disable your GPU with regular cgminer.exe.

Install VCP drivers, run bfgminer with the -S eruper:all -G parameters, that'll mine with the Erupters and not the GPU.  Remove the -G to mine with GPU as well.  Simple.

Or you could use cgminer to do the GPU mining, and bfg for the Erupters.

Personally I find bfg to be far better for the Erupters - I still use cg for GPU mining (basically because it's working and I couldn't be bothered changing it).

can i specify which erupter to use instead of all?
