Can someone else using cgminer confirm this claim? lolololololololololrofllololteeheeheeheehee

I have a very thin tip 40watt soldering iron, will this be ok to put some lead on the tip and make the bridge between points? or 40w is too much?

Use a multimeter. One probe on the outside, the other inside the barrel plug. Also check continuity between the yellow molex wire and the center of the barrel plug, and between black wire and the outside. Molex connector is fine up to 4 miners in scrypt mode.

I dont know how to check that?

for mine they just flash green lights when I have them plugged into the molex adapters I made, they show up in CGminer just fine and show a speed of 360 each, but they dont actually start accepting shares.

Is it possible that my molex adapters are not providing enough power?

or the PSU's molex cable isnt up to par?

lol, cgminer does this. That's why so many of us want to use cgminer and not 50 instances of cpuminer. 

I bought 20 GS's and split them between 2 750W power supplies because hopefully this afternoon I will crank up dual mining - if the IT gods cooperate

Did you double-check that you are actually getting 12V out the end of the barrel plug?

I had some weird things on mine. First off, I used exising power brick which has 5.5/2.5 and found it didn't fit very well, was very loose.

I noticed that when I plugged in the USB, that the lights came on (red/blue) and I could see it in Windows and start cpuminer, but the fan wasn't running and also wasn't getting any shares.
Tried re-positioning the barrel plug to get the fan working, restarted cpuminer and then it was working.
Could be that it kinda looks like it's running just from USB only but unless you get good 12V on the barrel plug it won't run properly.

So I fashioned my own power plugs with the barrel connectors and some molex adapters that came with my video card. Yellow In the + and black for the - then plugged them to a molex cable from my psu

They power my gridseeds but they don't get any accepted shares, I switched one to a regular power brick and it hashes and works fine. Any ideas?

If that would fix the daisychain problems with USB hub depth, I would be in

It just occurred to me. Wouldn't it be cool to have, as an option, all miners locally combined to equal one big hashing miner? What ever the number, you have them combined so they all receive work and report completed work 'yays' to the pool?
Instead of the pool seeing 10 different miners and combining and averaging them on that end, do it locally and have the pool see only 1 miner that is the equivalent of 10 hashers-hashing Hah! Gives me an idea for a Christmas carrol. Right, I know, it's way too frikkin early for that crap!
I wonder if this would yield higher overall completed shares?
Anyone hackers out there interested in trying out my theory?
Just an idear!

I have thought about something sililar yesterday.

Someone said that the miners run so cool that you would not even need fan nor heatsink, having just the board would also save up alot of space.

It would be awsome to find a way to connect for example 5 of these board together so that they work as a unit.

Like 5 Gridseeds, just one usb cable that connects them. Someone that could do this could make like a gridseed V2 @ 2000KH/s

this would be amazing

What about instead of using a Raspberry, would it not be an idea to run these on like the cheapest Intel NUC ?
those NUC like run something like 15watt

Cool.
I've always wanted to learn Unix-Linux. I do have a bit of uP programming under my belt, some assembly, machine and years ago, Windows.
I forgot about the --help call in cpuminer. Duh!

Im use to unix commands such as 'sed' where you can specify multiple identical flags, for example "sed -e 'foo' -e 'bar' ...", so it didn't bother me at all to give it a try. Anyhow, it doesn't work. I was told by someone that you can only run 1 GS per cpuminer, so I fired-up multiple cpuminers each with it's own COM port, and that's working fine for now. Eventually I would like to use cgminer.
As for the -G option itself, I ran "minerd --help" to get various alternate (and shorter) options.
Seems like many of the double-dash arguments offer a single dash version...

Where did you pick up the -G call in cpuminer. Is there a command list I don't know about? Please?
I mean, using it twice in the same flag twice in the same line. Really?
It seems that if so, it would allow one to run at least 2 miners as a 'team' in one window instead of 2 separate instances in two separate windows.

Hmm I have no com & lpt tab in the device manager.

but maybe this only appears when I'll hook up a gridseed to the laptop? ( I'm getting them soon )

Never mind. Narrowed down the gidseed having issue. Could be a DOA but will try playing with clock freq and such

what distribution are you guys using to compile cgminer?

the one that listed in the gridseek setup thread compiles fine but does not run on my pi rasberry - it just hangs

I need one that compiles and runs!

thanks

Can cgminer control more than 10 gridseed?


Cross linking here in case someone knows in this thread:
https://bitcointalksearch.org/topic/m.5788431

still can;t get cgminer to work
compile gies fine using instruction in post #1 of this thread.

has anyone else tried cgminer yet?

in any event - when attempting to run cgminer with all usb devices I get a segmentation fault.


and when trying it with a usb device defined it just sits there - although It does write some info to the syslog - rasberry pi

root@raspberrypi:/home/miner/usb-miner/software/cgminer# ./cgminer --gridseed-options=baud=115200,freq=850 -o stratum+tcp://us.ltcrabbit.com:3334 -u xxx.17 -p 123

it just sits there.

I also run netstat -an and it has not opened any connections either.
