True, I had a pi, unfortunately hated it and tossed it.

Get yourself a raspberry pi. Cheaper than running another PC.

Thanks. I ended up adding a second computer anyway due to usb problems. 128 device limit is bs. Mine couldn't handle 20. Or these serial chips suck. Wonder if prolific has the same issues. Ftdi Has always been a Bitch.

No I was serious. Took a while to find a psu with 2 8 pin pcie and turns out the splitter has it wrong.

The limitation is in the windows dos box, not cgminer. Open a command prompt window without anything running in it. If you right click on the top of the command prompt window you should find something like settings, and you can change the window size to include more lines every time you open it.

Alternatively you can start cgminer in the --compact form which will fit any number of devices but only give you the summary, not the details of every device running. A small text display was never designed with so many lines in mind

I don't know if your joking or not but yours has it too and your ATX power supply has that same connector.

Thanks.

CGminer: How can I use more than 15 devices?
How do I increase the window size? I can only see 14, hoping there's one more but the window won't resize.

Damn I spent a lot of time and money finding my PSU with all the right plugs.

From blackarrow. 600 watts to 20 lancelots.

Apologies, didnt know the full history.

My power break out box from Black Arrow had a 24 pin ATX connector on it. I used that one and only that one. Working fine for me.

Where did you get that thing?
Is that still available?
What wattage does it handle?

Yeah trying to pull 600 watts off only one connectors will melt it. You have to use them all.

I don't want to use linux :/ I have a windows server 2012 that I use for everything.

Great pics Bitpop.

I wouldn't have thought you would need to plug your PSU into every connector on the adaptor board.

Your using Windows on that old IBM of yours?  3.11?

Try Linux. cgminor on a USB stick.

Yay got my 20 Lancelots! In 6 boxes! Took over 2 hours to unbox and assemble.

PROBLEM: Blackarrow, your pci-e ports are wrong! I can only get 6 pins in, not 8! You seem to have used EPS sockets. What is the remedy? Will there be shorts or problems with only 6 pins or were you expecting EPS and I will get shorts? I paid extra for a PSU with 2 8 pin pci-e and this is frustrating.

Yay finally assembled and wired up!

PROBLEM: After plugging in 15 lancelots, any more and windows will say usb device unrecognized and the hub shuts the port down. It's not the boards because when I switch them out, they work if I stay below 15 boards. I don't think it's a Windows problem because even the hub refuses it.

Help! Cgminer, ever heard of this? I'm using 2x10 port hubs, uplinked to 1x7 port hub uplinked to one usb port on the computer.

Dwayne,

I'm sure we can help you. I'd be happy to help you get them up and running. I'm running mine on an RPI right now without any issues whatsoever (distro is Raspbian).

And I agree with Kano and ckolivas -- the bfgminer is nothing more then cgminer ripped off with the name changed. Its actually quite a shame that Luke feels he can get away with this.

Interesting history lesson.  I had no idea about any of that.  I am loving me some cgminer, glad I am with the legit dev team.  Right now I am just nervous about being able to get my first two Lancelots working with my power supply on my raspberry pi.  Windows+GPUs is no problem, but I am just a linux dabbler.

Oh and my 2 were just picked up in Hong Kong!  Can't wait.

D

We apologize kano.

Somewhat incorrect.
We don't get (or want) any code from Luke-Jr (hardly got anything from him for a VERY long time)
However, every release he has, he copies a lot of our new code to his clone.
Simply look at the commits in his git and ckolvias git.

The last big piece of code he submitted to cgminer was the MMQ driver last year ... which didn't actually even work.
He never sent the pull requests that completed it - which is why I ended up rewriting it in cgminer.

Here's where he cloned cgminer and changed the donation address from ckolivas to himself:
https://github.com/luke-jr/bfgminer/commit/b9df56511c7bd1a2e1f075e9c184c1a4b0f1ba20

Until the addition of the ASIC code, even his "BFL FPGA" driver - the driver that he goes on about being his masterpiece, he has less than 50% of the code in it in his git until the recent ASIC update.
e.g. back on 25-Jan the below command gave him only 34% of the driver-bitforce.c code written by him.
git blame driver-bitforce.c | perl -n -e '/\s\((.*?)\s[0-9]{4}/ && print "$1\n"' | sort -f | uniq -c -w3
(The above numbers have of course recently changed since he added his ASIC code into the same file)

However, in the master git right now it is now even more interesting (the ASIC code is in a separate driver in cgminer)

Though, that isn't as reliable as one would hope since for example not long ago he edited my API-README and changed the line breaks on 200 lines of it so it now says he wrote 200 lines of my API documentation.
He has also taken some of my code from cgminer and made claim to writing it or not put my name in the header whereas it was originally.

A simple example of the stupidity by him is visible in your post.
When he added himself originally to the AUTHORS file, after I was already in there, he decided he should add himself above my name
https://github.com/luke-jr/bfgminer/commit/9e40e87a1ed1003734a3aae114f7d1ac0643469d#AUTHORS

Also, as for my name in there, I used to have API+ next to my name (since I wrote the API and have written a lot of other code in there)
Oddly he decided to remove the plus and not add any of the other things I have done.
As an example, in his git right now, more of the Icarus code is written by me 45% (more than anyone else including him)
The php web code is written by me - and simply check even recent commits for code written by me all through his clone.

Or to be more specific:

So yes your comment is actually very unreliable.
