Title: Trying to setup ASICMiner USB erupter with BFGMiner, please help
Post by: bosco500 on August 05, 2013, 01:37:08 AM
I had my block erupter(s) working on Bitminter, but started having problems when I added more than 2 erupters.  I am trying to setup BFGMiner, but when I run the .bat file, I am getting an error "Failed to load opencl library, no gpus usable.  All devices disabled, cannot mine".

Can someone please point me in the right direction?  Sorry if this is a retarded question, all of this is new to me.

I am on Windows 7 32bit.  I have a single ASICMiner USB erupter plugged into the computer.

Thanks

I use CGMiner-nogpu.exe 3.3.1 with my block erupters and it works great for me.  It doesn't require OpenCL.

I would think BFGMiner would have a command line option to disable GPU support so that you don't need OpenCL, but I don't know that for sure.

Code:
bfgminer -o stratum+tcp://mint.bitminter.com:3333 -u UserID_worker -p **** --disable-gpu -S all

This will disable the GPU/Video Cards
Code:
--disable-gpu 


and this will detect all ASIC Erupters and to load all of them to run.

-S all

Dump it and re-install it.
Unzip it, create a batch file with the command I posted above and your good to go.

-G also disables GPU on the latest version of BFG.

You'd want -G -S erupter:all for BFGMiner 3.1.4 (which is far better for the Erupters than 3.1.3 and any version of cgminer IMHO).
