I see however, the problem rather be the CGminer itself, because it deregulates the stick for wathever reasons

'wathever reasons' is the problem.

Often as simple as a power source issue.

Hello Kano,

Thank you for your reply. Smiley

I've got a gekko usb hub with 120W PS and a fan running beside this miner. The power consumption of these can't be more than 5V/3A=15W + 5V/2,5A=12W, Sum: 27W, which is covered with the 120W PS abundandtly.

If I run two other miners + the fan there are no problems. They are running rock solid so the PS can't be a problem.

If I put this problematic miner in usb-port-pair with the others, it kicks the others out and they restarts automatically in about every 2-3 minutes.
If I run it beside them - not in a port-pair -, the two are running stable and this one is restarting with a reduced T until it gets to a point where the T is in the (-) minus range... Than it kicks the others out as well and they stop working.

I'm starting cgminer with the following line:

--gekko-compacf-freq 420 --gekko-start-freq 350 --gekko-mine2 --gekko-tune2 85

Now I lost nerves playing around with them days long without any success and let the 2 unproblematic without the other one running.  Roll Eyes

Added some simple troubleshooting steps at the bottom of the setup post.
May or may not be useful.

Of course the miner itself 'can' be faulty, but these steps, somewhat related to what you've done, point out specific testing.

Also, since that's an odd number to use, I'll point out that "--gekko-tune2 85" simply means:
every 85 minutes, if it's not "--gekko-compacf-freq 420", check if it can go faster
