Hello folks,
I'm Chris and i'm new.
I bought an Omegon veTec 16000C and i have some Issues. First, the cam works. But not very well. If i make in Kstars dark frames or sequence the imaging brokes  (kstars-bleeding installed from ppa stable release or nightly build from indilib.org).
Sometimes but it works. I think if the exposure 1sec or < 5sec it is better but not always.
I tested with Windows 10 and the original software a long time exposure  sequence with about 60sec x 5 images. That was working. I think the cam is all right.
If i use Linux Kubuntu 20.04 or Kubuntu 21.10 it fails most of the time. Not always.

I've made some logs and outputs form my system. I hope someone can help.
Thank You!!

UPDATE:
Tested with AstroDMx Capture and it works (Kubuntu 21.04 and Kubuntu 20.10)
I tried it again and found out that i can't make images in the normal sequence, too. I get always the same error:

Toupcam ATR3CMOS16000KPA : "[DEBUG] Capture timed out, restarting exposure... "

I tried the other "drivers", too. Touptec, Omegon and Meade. Same problem. What do i wrong?  What settings do i need?

I changed my /udev
from:
SUBSYSTEM=="usb", ATTRS{idVendor}=="0547", MODE="0666"

to:
SUBSYSTEM=="usb", ATTRS{idVendor}=="0549", MODE="0666"

but nothing ...

UPDATE 14.11.2022
in the meanwhile, the cam works fine with an update... don*t know the version of kstars. Now, another update later (one or two updates), same problems, cam doesn't work again.

Here my logs and outputs:
