I just recently have seen a few COMPACS begin to surface on the net here and there. If anyone has 2-3 new units for sale, please contact me for an immediate sale! Thanks.

"nice" premium, maybe wait a couple of mo for a new version (likely to be 3-5 times faster).

Hy everyone. It's me again 

After all I've bought a new setup (after I red some advices which were given me here in this thread):
 - 1x Raspberry Pi 3
 - 2x D-Link 2.0 7 active USB-ports (5 USB ports, 2 charging)
 - 4x Y-cables

I've choosen the raspbian image and compiled the cgminer version from gekkoscience.com.

I want to set my 4 gekkos (EU-Version) with 250MHz but 225MHz seems to be "the magic border".
Only 1 or 2 of the 4 miners do run. The rest is marked as "ZOMBIE". If I try to hotplug (warm the miner a little up
with my hands) and put it back in the Y-cable slot it says: Gekko detect (1:11) failed to initialise (incorrect device?)

Is anyone able to help?

[sidehack]

Have you turned the voltage up a bit from stock? What's it currently set at?

[raiding]

Yes. I've turned it up to 0.77V.

Hotplug the troublesome ones a few times. One of my stickers used to take quite a few plug and unplugs. Also try restarting the raspi if it fails to recognise it completely. Turn the freq down to 200m and start them up, leave them running then restart the raspi at a higher freq. I just leave mine running at 200m for the sake of 1Gh difference it's not worth having them stopping all the time and having to restart.

Have you got an auto run setup on the raspi?

[raiding]

Thx. I'll try that.

I put several stuff  in my /etc/rc.local for startup. The cgminer-part:

screen -m -d -S ckpool /home/username/cgminer-gekko-rev2/cgminer -o stratum+tcp://solo.ckpool.org:3333 -u bitcoinaddr.workername -p x --compac-freq 200 2> /home/username/cgminer_log/`date +%Y_%m_%d`.log

Looks good to me. Let them run at 200m for a few hours and then turn them up to 210m for a few hours. Do it in increments

Hey

I was trying to hotplug the troublesome gekko a few times. Tried different tactics (short period of time to wait and often replug and long wait ..) nothing worked. I still get "failed to initialise (incorrect device?)"-error.

What am I doning wrong?

You've restarted the raspi with them unplugged and plugged them in one at a time? You've got both hubs connected to the pi? As usually one side of the "Y" cable is power only and the other side transmits data and power.

[raiding]

No. Everytime I started the Pi I have the gekkos already plugged in. Is this not the common way?

Both hubs are connected to the Pi. I plugged in the Y-cables with all ends in the data-ports (I could use the amp-only ports for the power cable from the Y, but I have fewer errors if I plugged both in data. It doesn't matter anyway I think cause the second data should provide enough power for 200MHz (correct me if I'm wrong)).

Yea two data ports should be fine for 200m. Leave the y cables plugged in and unplug the gekkos. Leave one plugged in so it finds it and starts mining. Then plug the others in one at a time.

[raiding]

Ok, I tried.

I powered off the pi, unplugged all gekkos except one.
Then I started the pi, let it boot and waited until the gekko lightened blue.
After that I plugged in the others one at a time (I logged in via ssh on the pi first, so I could see the cgminer-screen).
But none of these were recognized. I tried plug and unplug them again, nothing happened.
Not even the cgminer-screen displayed some hotplugs or something.

[gt_addict]

Its very strange that it recognises one but not the other two. Try the same process again but with a different gecko to see if it gets recognised.

[raiding]

Exacly the same ..
I tried each of my gekkos (which were recognized, but 20% chance of libusb-error) and also tried to plug in two miners first and after that the other 2. Hotpluging seems not to work for me. Did I miss some configuration?

[gt_addict]

I followed a guide on the raspberry pi forum (after googling it) but changed a couple of parts to "wget" and then unpacking the tar file from the gekkos site that's listed on the first page. Also it's running raspbian that I got from the raspi forum aswell. Not sure if you've done anything different but it works for me.

[raiding]

Are you using the american or european version?

[gt_addict]

To be honest I'm not sure. I got it from www.raspberrypi.org
