Hi, I have a Lenovo Thinkpad T580 notebook connected to an i-Tec docking station via usb-c cable. All USB peripherals (mouse, keyboard, etc.) and 2 monitors (HDMI) are connected to the docking station. I used DisplayLink driver to make everything working fine until the version 5.4.0.89 of Linux kernel. With version 5.4.0.90 and the latest 5.4.0.91 a strange situation occurs. Occasionally the monitors darken and even the mouse does not respond. From in-depth analysis it seems that there is a problem on the USB bus for which the devices are disconnected for a few seconds until everything starts working again. It is definitely a problem related to the new kernels because everything was fine with the previous ones. Anyone have an idea and can help me? Thanks

Facing the same issue. I also think it's related to the latest kernel / firmware somehow. Not sure if it is a Displaylink problem at all, maybe it's connected to USB firmware. I have only bluetooth mouse / keyboard and cannot connect my monitor directly to the laptop. Maybe to test, can you connect everything directly to your computer and see if keyboard / mouse stop working at some point? That would indicate a problem with the USB firmware itself which then kills our displaylink docks as well :mad:

I just remembered that i had this fix applied before. Trying it again now, either it got vanished due to some update or at least something reactivated this behavior. I think I remember that I had undone this fix after some upgrade and it was working fine since but now it started again. Comment out this line in /etc/pulse/default.pa Code:

I tried to connect mouse and keyboard to the notebook instead of the docking station. I have the same problem. There is something related to kernel that cut usb. It can't be explained in any other way.

Maybe you can open a support ticket for it? I don't think this forum is actively monitored by the staff at all times.
