Lightbulb USB-C Dock is switching off while monitor is displaying

Hi,
HP G6 USB-C Docking station
HP Probook 650 G5-C port.
I start the laptop via USB-C Dock. Two external screens are switch on, I can logon, but then the USB-C Dock is switching off =:-/
When I power recycle the USC-C Dock, then I can switch on again, but the it take a while and the the USB-C Dock is switching off again.
I assume it that the Laptop is switching off the USB.

I cannot really judge, what is going on.
I paste the debug text, which I get, after the USB-C Dock has switched off!
And I attach a txt-file with output from dmesg.
At the USB-C dock to monitors are connected: One on HDMI, one Displayport. Third port on USB-C dock is not used. I'm wondering about the 5 providers listed below. Maybe the laptop screen, HDMI connector in the laptop, the one HDMI plug in USB-C dock and the two DsiplayPort plugs.
