How many gekkos are you able to run with one plugable? How much speed do you get (average) ? Does it run stable or does the pi "freeze" after a couple of days? Does it work without Y to?

Wow. Looks great! It's also avaiable in my country

I think you're right.
I tested the dlink with just one gekko. 200MHz unstable, 225MHz no response ..
So I think I need a 70W USB hub (unfortunately amazon isn't selling the Superpbag in my country. Hopefully I'll find it somewhere else in the www
)
Thank you all very much for your help!!

Plugable hub also works with pi and compac's:
https://www.amazon.com/Plugable-Charging-Adapter-Support-Android/dp/B00L2LK164
This is a BC 1.2 device, which means that it allows up to 1.5A per slot (limited by a total of 5A/60W).
I added Y's to it and was able to run compac's on it at a very high speed with heavy cooling, of course, just for kicks.
It does not matter that it is USB 2.0, hashing is unaffected.

my 5 compacs run on a rpi model b, stock rasbian image, with a superbpag 70 watt hub and an artic cooling usb fan on them. cgminer-gekko version, compiled from source.
i run root on the rpi and ssh into it. once in a while from cold boot all the compacs do not come up running, i just warm boot the rpi again and they usually come right up. never had to "hot plug" them.
compacs run at 300 mhz with 0.70 volts set on my mulimeter.. thats from recollection, might be wrong on that voltage though.
just listing what works for me. ymmv of course.
EDIT removed some unneeded stuff.

I was running the US AND EU versions on the dlink hub no problem.

correct
compac =>USB3 Superbpag => DLINK USB2 => RPI3
at 0.77Vcore, you stick should draw 7W, that's 21W (ish) for 3.
can you hub deliver 20W ?
I can of course be very very very wrong

Wow. Your construction looks very awesome! Nice done!!!
Just for better understanding:
You plugged in your gekkos into the usb 3 hub you'd recommend me. All of your 6 without Y-cables (so you only need one of these usb 3 hubs). Then you plugged in the data-cable of the 3 hub into a random usb 2 hub and the 2 is connected into your pi 3. Am I right?
I've bought several hubs, too ... so I want to be 100% clear, you know
But I'm confused about your statement the d-link can't provide the power which is needed by the gekkos.
The hubs were also recommended to me by another user in this tread. He argued, that the hub has 2 charging-ports which can be used by the Y's to provide as much power as needed ... is there a reason in your opinion why your solution works and the d-link doesn't?
Or is the d-link just trash for mining?

3 compac on the DLink hub ?
with Y cables ?
this hub ?;
I've had issues with this one
I'm now using this one SuperbPag 7ports, with 6 compac @300Mhs
https://www.amazon.com/Superbpag-Portable-Charger-Transfer-Samsung/dp/B013OK10YM
You may be over what the hub power can deliver.
I did a lot of attampt at running multiple compacs (I have 6 running)
I used several 10 ports USB2 hubs on RPI: worked more or less
I used a usb 3 hub for power and a usb 2 hub for data on a RPI: worked
I used a usb 3 hub for power and a usb 3 hub for data on a gibagyte Brix: worked
I'm currently using a USB 3 hub plugged in a USB 2 hub on a RPI: works
cf https://bitcointalksearch.org/topic/m.14582497
(i've since replaced the Y cables by normal cables for tidyness)
with Y cables ?

I'm sorry: I was meaning which version of the gekko are you using 
October 22, 2016, 04:26:42 PM
To be honest I'm not sure. I got it from www.raspberrypi.org
October 22, 2016, 04:06:43 PM
Are you using the american or european version?
October 22, 2016, 02:39:55 PM
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.
October 22, 2016, 01:00:18 PM
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?

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.
October 22, 2016, 11:52:35 AM
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.

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.

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.

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
