I would like to help, but I have not seen that error specifically.  Can I get a little more info about your setup?  What OS, How are you powering, did you rebuild cgminer,etc?  Maybe get a little more cgminer output?


I don't know if they will detect correctly, as the icarus driver specifically can detect anything with approximately the correct chips.  You can try, you'd need top build with --enable-icarus and --enable-gekko.


Here you go:

Thank you. I posted a question for you on another thread do you know if I can run older U2's in the same instance of cgminer or can I only stick to the compacs id like to fill the rest of the hub with my older U2's and ahve only 1 pi 2 running them all

Nice rig! Thanks for sharing the pics.

Novak can you provide a diagram showing the voltage adjustment position in relation to voltage I use the flat surface as a guide and with it directly flush with USB port I have been able to get to 250 mhz or so no HW errors I dont have a volt meter handy to test what voltage that brings me up to

You can run minera on all editions of the Pi I tested the cgminer-gekko on a Mac runnign windows 7 Vitual Machine worked great today I built out a fresh pi image on a Pi 2 and its running more stable also using a much beefier USB hub with 60AMP of 5V power

One of them needs a little more voltage
I just got it up and running Minera modified edition on raspberry Pi 2 running great with 10 Sticks Clocked at 256.25 Screen Shots of setup below

I haven't run cgminer-gekko without minera, but my guess is that there would be no actual difference (other than usability). The mining itself is handled by cgminer.

Minera is just the management application. It makes it easier to change the config (if you like GUI interfaces over config files) and it provides a nice summary of statistics in a nice looking web GUI. It also takes care of things like starting the miner at boot, auto starting if it crashes, and stuff like that.

But under the hood it's still just cgminer running under screen.

Has anyone tested to see which is best on RPI Minera or Raspbian running cgminer?  I thought I would get it today, but looks like Tuesday I'm getting a RPI model B.

Just wondering if anyone has tested both.

So far my biggest issue is going past 2 sticks.  All 3 pc's windows 7 or windows 10 act poorly once I add a third, fourth, or fifth stick.

I can run two sticks as high as  freq 350  I NEED A REALLY GOOD FAN FOR THIS! But they run fine.

If I do 3  or more sticks on the same setup even at freq 175 they start dropping hash.

Not liking this issue.  Has anyone been running 4 or  more sticks with good results.

did you use zadig to change the driver ?  the compac has silab…  needs to be changed to winusb
here are 5 compac's all have had the driver changed by zadig

Thanks for the tip

Trying CGMiner now. Getting a "Failed to initiate device" error. It recognizes the devices.

Using ./cgminer -o stratum+tcp://peercoin.ecoining.com:3336/ -u blackbird.2 -p 12345 --compac-freq 150

Tried another build on the Pi2 with 2015-05-05-raspbian-wheezy , this time from putty I restarted cgminer with the "s" and then "c", after restarting it shows

"fatal json error in configuration file"
"configuration file could not be used"

I have been doing the builds with libjansson-dev, so tomorrow after work, I'll try one more time with out it and see if that takes care of the configuration problem with the pi.

Which I think it will.

my next project is to build a minera Pi 2 and run all 10 off of my eyeboot 49 port hub with 60AMP 5v Power Supply and some additional cooling

Picture of my setup and screen shot of cgminer

Yes I wasn't able to get them to hold there without turning the dial up. I also have a USB hub rated at 2 AMP per 2 outputs I cant put 2 sticks in or I get unstable so just 1 stick per group of ports rated to 2AMP they ran all night long 4 sticks Average 42GH with about 217 HW errors

I'm assuming you also turned up the voltage to get to 250MHz?

I got mine today running them on a VM on my mac i wasnt able to get bfgminer to work but the cgminer worked after copying the missing .dll file from a previous cgminer folder I have 4 running on a small test USB hub at 250 mhz with a fan running great. Any higher and I find they start to become unstable think they're hitting their power limit of this hub

I did the same with w 7.  And w 10

OK, ran in to a problem with the Pi/Raspbian and cgminer-gekko, it will not write the cgminer.conf file. Every time I use "s" then "w" it ask for name and I hit enter, it stops  (also try typing in /home/pi/cgminer(even cgminer-compac)/cgminer.conf).

I'm trying to add more pools, so I can run 1 stick at philipma1957 Sidehack stick solo pool club and then have 4 pointed at solo.ck my self.

I've got it set to where it starts mining as soon as the Pi starts, but all 5 sticks are on 1 pool, until I add 4 more pools with "p" and "a", and switch to balanced (trying to get everything automatic (no typing)).

1 time when I tried it, it did make a cgminer.conf file, but it was blank. So I edited it to add the pool info (copied from another cgminer.conf file):
{
"pools" : [
   {
      "url" : "stratum+tcp://stratum.kano.is:3333",
      "user" : "Jake36.worker3",
      "pass" : ""
   }
]

Tried without the api and worked my way down until all that was left was "compac-freq" : 150.

Anyone got any ideals?  Getting ready to put Minera on a SD and give it a try probably tomorrow.
