I added pause, this is what i got. if i press enter it closes.

Its doing what its meant to be doing, I still suspect its some form of antivirus or windows defender which is closing it as its shutting down at a point that cgminer never would do so itself.

But, i can mine with my graphics card, at 500mhs. I just allowed cgminer through my firefall though just to make sure, still the same. all went into task and turned off all antivirus.

It has to be something silly im missing.

So i downloaded cgminer 3.8, ive been trying every version now. and i got this . . . when i plugged it into usb 3.0 slot, usb 2.0 it does the usually.
What does this latest event mean?

But you're not mining on your graphics card with this particular instance of cgminer. Maybe CK will have some ideas as to what's going on once he's back.

Are you using a USB hub? Is it powered? USB 2, 3 etc?

Probably a hardware issue, most likely vreg bugging out.

I have the same problem this morning

[Iskavan001]

I unplugged and replugged into my powered hub, and my desktop, all ports. 2.0 and 3.0

To the ongoing discussion on cgminer: Currently using cgminer 4.9 with the options --au3-freq 245 --au-volt 785, working just fine on windows.

Had two U3s for a few weeks now, tested both on my windows and linux setup with cgminer 4.9. They are easy enough to use after cgminer got support for them and extremely silent, compared to for instance my old butterfly jalapeno. But, they are not so very stable or well performing, but it varies a lot. For the most port, one of them has given me an average around 57-58 gh/s, the other one around 45-46, consistent across machines. And one usually zombies every day or two. Now suddenly, they have both been averaging around 57-58 for the last 30 minutes after i unplugged for a little while and restarted cgminer.
Using the power supplies that came with the units, bought from cryptocrane on amazon.com. Bit hard to understand whats going on with these units and their performance...

For some reason they average higher on my windows box than ubuntu 14.04, a little difference in hardware though. Faster wireless on the windows machine as well.

[Iskavan001]

visvas what do you type exactly? I have to be missing something stupid.

[Visvas]

cgminer.exe -O username:pass -o stratum+tcp://pool:port --au3-freq 240 --au3-volt 785

the latest 4.9 version downloaded from the compiled binaries folder. If you have multiple cgminer versions, like me, make sure you're in the right directory as well:)

[Iskavan001]

Visvas, your code is different from every other guide ive found, sadly it still does not work for me. Thanks though.

Hmm, the lock is a separate issue and usually requires a windows restart to clear. Then replug and check zadig again because it can drop.

[Iskavan001]

yeah tried that, and downloaded an older version of zadig to try that.

I'm out of ideas, sorry. Could be anything software wise causing it, or simply hardware. Please contact BitmainWarranty if you would like to arrange a replacement (if you bought directly from Bitmain). Else, contact your reseller.

What version of cgminer and OS are you on? Also, have you used zadig to replace the usb drivers for U3? When you say it's not working, what kind of error do you get?

Thats the switches relevant to UE3 in the Readme of the latest cgminer, but yes, i know all of the old guides out there. cgminer addedd native U3 support in 4.8 release.

latest build, using this on my windows machine.

If you read back to previous posts i believe pages 20 and 19 i begin my quest to get this working. So you can get idea of what ive tried. I use windows 7 though, and ive tried it on rapberry pi raspbian. I have used every version of zadig i can find and ive tried 3.1 .3.8, antiminers cgminer and 4.8 and 4.9 of cgminer.

SO i was repackaging this to attempt to send back to amazon and i notice the 4 screws in the fins on the bottom are not even half way in, should they be screwed all the way in? things life up on the inside when i press them.

I am trying to run this from the command line in the cgminer 4.8 directory

cgminer.exe --bmsc-options   115200:0.54  –o   stratum.antpool.com:3333
-u(myuser) -p(mypwd)   --bmsc-voltage   0800    --bmsc-freq   0982 --startdiff   6

And I keep getting unrecognized error on all of the options.

Can anyone fill me in what am I doing wrong?


And once it goes ZOMBIE, is there another way to reset it without reseating the usb cable?

As far as i understand it, the guides showing you those settings are quite outdated. After 4.8 you don't really need to give any switches to get u3 to work pretty well i believe. And if you run cgminer.exe --help you'll see the available options. For mye 4.9, its the --au3-freq and --au3-volt thats relevant. And for those, the parameters are straightforward decimal numbers. 785 to specifiy 785 mV and 240 to specify frequency for instance. Just a few posts back i give an example of what i have working with  UE3 and cgminer 4.9

You could try something like cgwatcher to automate fixing and monitor your mining, with regards to your (too normal with ue) zombie problem. But for me that didnt work to well, cgwatcher freezes my whole machine up...
