so remove it

[hurricandave]

I think GPU is disabled by default, unless you specify opencl the miner will ignor GPU and CPU without any additional action needed by the operator.

That's the USB hub I'm using.

Figure that I'm a noon and you need to help me remove or add stuff to my config.

try starting with a batch file instead of a config file.
BFGminer will create a config file for you when you have the setup working correctly.

here are some sample .bat lines:-

1) for antminers               bfgminer.exe  --set-device antminer:clock=x0981 --icarus-options 115200:2:2 --no-submit-stale -o http://stratum.bitcoin.cz:3333 -O worker:password -S antminer:all

2) for erupters                 bfgminer.exe  --no-submit-stale -o http://stratum.bitcoin.cz:3333 -O worker:pasword -S erupter:all

EDIT:- what is the rating of the PSU for the hub?

[FaSan]

I've read on the bitcoin sources code (already from 0.8.5 version) that the getwork "midstate" and getwork "hash1" are to consider "deprecated".

I've test if miner will work without this, but not. Have you plan, already, to update the miner for work fine with getwork "data" and getwork "target" only ?

I'd suggest people be careful with setting no-submit-stale.  
Some pools like BTCGuild pay for stale/orphan shares and not submitting stales in this case would be like refusing free money.  
Also in the case of P2Pool, a stale share on the p2pool chain may actually be a valid solution on the Bitcoin Blockchain, so you never want to set no-submit-stale when connected to P2Pool.
In the case of some scrypt based multi-coin pools (Middlecoin, Hashcows, Wafflepool, etc), you also want to submit stales because BFGMiner may think a share is stale during a coin switch when the pool may accept it.

Can't forget one of the newer multi-coin pools (the one I'm having fun with):  multicoin.zapto.org:8080.  Its scrypt only at the moment, but still under active development.  Would love to get your comments on it.  I'll ask about stale/orphan shares.

I believe The AntMiners use the same Watts as Erupters (~2.5 watts). Does the AC Adapter say it'll do more than ~18 Watts?

for 5 ants and 2 erupters I would be looking for at least 26 watts at the Wall (even better with 30 watts)
the losses in the hub (as heat) could exceed 1/3 of the total available.

usb3 hubs with 9 or 10 erupters and 12v 4a (48watt) PSU soon fail. Many have been replaced with 60 watt units.

Yep, went with http://www.amazon.com/Charging-Adapter-VL812-B2-Chipset-Firmware/dp/B005NGQWL2

Specifically to avoid premature failure.

As for DBC's issue. I would pull the Ants that are hashing at the expected rate and see if the other two 'pick up speed'. If so, then it's a power issue. If not, then they may be defective.

[dbcmaster]

I just removed the two block erupter usb sticks and now the antminers are working as expected.

This is the power supply: Input 100-240v. 50-60Hz. Output 5V -- 2500MA. Model: SAW-0502500

Looks like not enough power. That's only 12.5 Watt output.

Or 2.5 amps @12v (2500ma).
barely run 5 ants with that. ants are .06a and higher if clocked.
Do not be tempted by USB 3.0 hubs, some work most do not.
All present USB miners like/use USB 1.1/2.0 spec.
Watts spec is misleading use AMPS.

[dbcmaster]

Any recommendations on a power supply?

You'll want a second opinion on this.

But it'll definitely have to be a supply that outputs at 5 volt; anymore and you'll be investing in a fire extinguisher
--So you'll want one with more Amps.

You'll also need to match the polarity of the plug end going into the USB Hub; see above's additional investment if you don't


As for which to look for...I'm not sure if a 3rd party PSU can be used with 'commercial' USB Hub.

Hi, using a mac and i hit m to add antminers but I'm not sure what the path is or how to fnd the path to my antminers.
here is the example i get,erupter:/dev/cu.SLAB_USBtoUART
thanks in advance.

Presuming you are talking about Antminer U1s you need to use "-S antminer:all" and optionally "--set-device antminer:clock=x0981" or whatever clock you want.

Oh, you MUST be running 3.10.0, not an older version, too.

Being masochistic, I like to start my mining week out from a common spot, so I tend to pull the latest bfgminer git, install, and reboot my (3) miner machines.

Tonight being the night for such things, I found I'm having a new quirk:

Miner machine #1, with (2) GPUs, is working as expected:

Note that both GPUS are reporting their temps.

Miner machine  #2, with (2) identical GPUs to machine #1, is only reporting temps on the first GPU:

Miner machine #3 is acting like Miner machine #2.

I rather like seeing the temps as it allows me to tweak intensities to keep at or below 80C (wouldn't want to burn any out too quickly!).

Start-up scripts have not changed in weeks.  Typical command line:

./bfgminer -S opencl:auto --intensity 17,18 --temp-overheat 90 --temp-cutoff 100 --temp-target 80 --scrypt --gpu-fan 100 --auto-gpu -o ...

Any ideas on what I broke?  

[Luke-Jr]

More likely I broke that... Can you perhaps pinpoint which commit caused the problem?

Thanks
