USB cut off

snipe122 · 01-10-2022, 10:06 AM

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

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:

### Automatically suspend sinks/sources that become idle for too long
# load-module module-suspend-on-idle

I'll report back how it goes. Just had a blackout before and applied the fix now. If I don't get another blackout during the day I guess this fix is working again.

Just got a blackout again, you can forget about this "fix" then.

I was hoping...
I didn't try yet to connect mouse and kboard directly to the notebook because I always forget.
I will

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.

Any other idea or suggestion?

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