Hi, I’m a new user of Opensuse Tumbleweed and I have installed it on a X1 Carbon laptop. I have a dock station for it, a Displaylink, that is recognized, but not in a stable form. That is, the dock is connected, but after a minute or two it is disconnected and quickly reconnected. And this happens continuously, almost every minute. This causes a temporary fall of internet connection and the unmounting of the external hard drives associated through the dock station.
When the dock is connected lsusb give this output:

It’s really a problem linked to the kernel. With the 5.2.10-1.1 kernel the dock was working fine. But with the following kernels the dock station no longer worked properly.
What could I do?
Thanks in avance for help.
