DisplayLink Driver service turns off and on
 

Hi,
Device that I am using: https://i-tec.pro/pl/produkt/u3dual4khdmi-7/

I have a problem with display link on ubuntu 20.04. DisplayLink service starts and stops every minute.

Any idea what could be causing it?

I have found that one of the HDMI ports connect/disconnect all the time

Maybe device is overheating or can be physically damaged?
