OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[Mikestang]

Had a power outage yesterday, since then I've been getting weird errors with my nanofury usb sticks.  They'll run fine for a while, then this starts:


The only cure is to quit cgminer, physically unplug and replug each stick (some of them the mining light stays on even after quitting cgminer), then restart cgminer.

Any ideas what is causing this?  Thanks.

Looks like a fatal error on the sticks - they're just not talking back. Not sure how they would have gotten damaged by a power outage but they look like they've had it. Each and every one of my nanofuy USB stick based miners eventually died on me.

Each and every one of my nanofuy USB stick based miners eventually died on me.

Hmm, well that's disheartening to hear.  I had one die on me months and months ago, but I had it OC'd and was just asking to burn it out.  These 6 have been champs since that one burned out, I've run them at stock setting with a fan the entire time.

The screen cap above shows errors only on one stick, maybe I've got one bad apple in the group, I'll mess with them tonight and see.

Does the fact that they come back just fine for a while (hours at this point) when unplugged/replugged not mean anything?  Just another symptom of their inevitable demise?  If so then I just got room for a few more compacs.

Not really. When I say mine died, they all ended up like that - they'd start up ok but last progressively less time before dying. Think of them as evolving into antminer U3s (in a bad way).

I'm trying to get a config file to split hashrate between 2 different pools.  I'm running on Win7 with a gekko usb stick.  I would like to run maybe 50% on pool1 and 50% pool2.  I have the following code:

Code:

cgmine  --url stratum+tcp://solo.ckpool.org:3333 -u 1JiWuyX94wrCr7JhkAn7x5qNMCEef1KhqX.Chris_Sabianstick -p passa --quota stratum+tcp://solo.ckpool.org:3333 -u 13fKi6ND8mbiAnD4DCj9wg3P9CXyFzFvCi -p passb --compac-freq 155 --usb :2 --suggest-diff 10

I believe that I just have a simple error or two somewhere.  Not sure where of if I'm even getting the context correct.

If you just want a 50/50 split, I'd suggest using the --balance option instead, or use --load-balance without setting quotas (they default to an even split across pools).  You do need one of those commands or else it'll just be in failover mode, regardless of you having used --quota

In terms of your command line, have a look at the documentation:

Code:

--url poola:porta -u usernamea -p passa --quota "2;poolb:portb" -u usernameb -p passb

"Will give poola 1/3 of the work and poolb 2/3 of the work."

so in your case you might use any one of:

Code:

--balance --url poola:porta -u usernamea -p passa --url poolb:portb -u usernameb -p passb
--load-balance --url poola:porta -u usernamea -p passa --url poolb:portb -u usernameb -p passb
--load-balance --url poola:porta -u usernamea -p passa --quota "1;poolb:portb" -u usernameb -p passb
--load-balance -quota "1;poola:porta" -u usernamea -p passa --quota "1;poolb:portb" -u usernameb -p passb

Yet another alternative would be to use the --rotate option, presuming the pools perform much the same then rotating through the pools every N minutes has roughly the same 'even split' effect.

Thanks!  I was able to get what I needed from your code.

  For some reason, I was messing up the poola:porta part.  I didn't realize that it was poolA:PortA .   ugh.  I guess this is why I'm not a programmer. I was looking for a 'poola' command...

Hi, everybody,

I need help with 4.9.2

I have - 
Windows XP sp3
Antminer U3
cgminer 4.9.2 from official download page.
All drivers are installed

The problem with 4.9.2 is the next - it doesn't start with batch file in any syntax. No matter cgminer or cgminer.exe. That means I have to start my cgminer manually everytime and run it with standart freq 225/volt 775. I did the conf file with changes in --au3 lines from default 225/775 to 250/850. The conf file is in the same folder with cgminer as well as the batch file. No results at all. If I start the batch file the cmd window appears and drops in ½ second. If I start cgminer itself it come and works but with default 225/775! How I can organize start with batch file and change the settings for my u3?

There were no problems with my previous  cgminer 4.6.1 at all except the speed and tons of errors. Now with 4.9.2 and default settings for u3 I have speed up to 54 Gh/s and 1-2% of dups/stoles. The only thing that makes me sad is the configuration and batch which still useless.

Could you give me any suggestion?

The sample of batch I try to use - "cgminer.exe -o *** -u *** -p *** --au3-freq 250 --au3-volt 850"

I thought that the batch file with just "cgminer.exe -n" in line will start cgminer and show the settings for device. But this one doesn't work too...

[os2sam]

Put a pause after your command line so that you can see what the error. 

such as

cgminer.exe -o *** -u *** -p *** --au3-freq 250 --au3-volt 850
pause


Or open a command line dos box prompt and then type in your complete command so you can see why if failed.

[maximcmd]

Thank you! Adding "pause" to the .bat file works perfect, cgminet starts with .bat.

There is another problem I found trying sugestion #2, using full command line in cmd - it says that devices found: USB 0; BUS 1 (and this is my u3!)
 I am confused... It works perfect if I plug U3 to the desktop, U3 is recognized as usb device. But when I move it to the laptop it is recognized as BUS device and I do not understand why there is no connection to usb port. Both computers are with XP and have similar tree in device manager...

Did you install the WinUSB driver via Zadig for WinXP?

[maximcmd]

Yes, I did. I did install 2102 usb to uart bridge controller and change driver to WinUSB using Zadig (with plugged U3 as it's written in the instruction to U3
)... Should I reinstall the driver? Or install the controller again?

Run Zadig again, select "list all" and verify that all your miners are using the WinUSB.  Also copy and paste the error your getting so we can see what you are getting.

[maximcmd]

I am not sure I can copy-paste from cmd line. But in words some results -
1. When I start cgminer directly without .bat it still quiet for a while. I see that cgminer is connected to the pool but there is no section with usb device settingsand nothing happens in sense "accepted/rejected/duplicate/etc."

2. When I start with .bat file from previous post it still quiet as well, but after a few minutes starts to send messages Libusb attempting to reset and libsub Success every 5 seconds. No more information.
3. If I start by entering full path to the .bat file into cmd line it says - "cgminer.exe is not an executive file"
4. If I start with batch "cgminer.exe -n" to get information about devices i see found usb device 0; bus 1 (and this is the one that match my u3).

There are no error messages or "failed to..." stats.

Maybe it will be helpful to set the WinUSB to all listed devices from the zadig's dropdown menu? I do not go to use this laptop for other works than mining and hope that changing all usb drivers from current to WinUsb will not affect adding or moving files from usb-sticks and back.

Looking for solution to get at least screenshots of cmd. Will be back with pictures soon )))

[os2sam]

I am not sure I can copy-paste from cmd line. But in words some results -

In the dos box go to properties and check the quick edit option.  Then just select the text and copy it to the clipboard.

2. When I start with .bat file from previous post it still quiet as well, but after a few minutes starts to send messages Libusb attempting to reset and libsub Success every 5 seconds. No more information.

Unplug and replug your miners.

3. If I start by entering full path to the .bat file into cmd line it says - "cgminer.exe is not an executive file"

You must have your path wrong.

Maybe it will be helpful to set the WinUSB to all listed devices from the zadig's dropdown menu?

I would not do that.  Just do it for your miners.  How many miners are you connecting to WinXP.  XP has a limit of 12 or 13 devices.

[hurricandave]

Well, since it has not been clearly stated. Did you install the Zadig driver, then, unplug the device, then, replug the device, into the same USB port? CGMiner will not see the device until you have reset USB by unplugging it. Some need to take the extra step of removing power while its disconnected to completely reset. Once you have reset the device, double check the driver properties before launching cgminer.

[maximcmd]

I did reinstall zadig driver, unplug, plug again and run cgminer with command "-n". Cmd comes up with next -

C:\Documents and Settings\cgminer-4.9.2-windows>cgminer.exe -n

 [2015-10-13 14:13:02] USB all: found 8 devices - listing known devices.
USB dev 0: Bus 1 Device 1 ID: 10c4:ea60
  Manufacturer: 'Silicon Labs'
  Product: 'CP2102 USB to UART Bridge Controller'

I did check usb-port settings with plugged in the same nest usb-stick first and then with U3 by AIDA64. The results are different...
Usb-stick appears on the first port with correct settings (USB 2.0/highspeed)
U3 appears on the last port and settings are USB 1.1/fullspeed

That's strange.

Also the results from PC Wizard 2008 look very strange - I found U3 connected  but with wrong usb settings

Actually, I wonder for which reason my laptop has 5 (!) PCI-USB host-controllers, 4 standart with 2 usb ports (as it is physically) and 1 extended with 8 ports - two from which are busy with camera and generic C-RW...


There is also a copy of my conf file -

"au3-volt" : "775",
"no-submit-stale"
}

>>>

The .bat file is with the same settings

I still not able to get a copy of messages from working cgminer's cmd window, it starts with the message of "fatal JSON error in configuration file" (the same file on another machine works perfect), then "no hotplug usb devices detected", then 5-6 minutes it stays calm and after this pause come LibUsb Errors reset/success...

-ck,
Did you know that Firefox is now blocking your web pages?

Never got a fatal json error before.  Hopefully someone else can chime in on that one.
Good Luck,

The U3 is notoriously fickle and a piece of crap (see the U3 thread in hardware).  I would suggest that much of your difficulty may stem from the device and not cgminer, per se.  Do you have any other mining devices you can try?
