Problem description:
My mouse and keyboard keep randomly getting disconnected and they do not receive any more input signals after that. The solution at the moment is to physically re-plug both devices until the issue reoccurs.
For context: I have somewhat of a weird hardware setup. My whole periphery is connected to a Dell WD22TB4 USB-C docking station and the USB-C cable of the docking station is connected to the USB-C port of my GPU. This hardware setup worked without any issues when my PC used to have Windows installed on it. The setup also works with on my Dell laptop which I use for work (both Windows and Ubuntu in that case).
Some additional information: When the issue happens both mouse and keyboard are disconnected at the same time. When I type while the disconnect happens, the last key input keeps repeating indefinitely until I re-plug the keyboard. I have also noticed similar behavior with my two monitors where one of them would randomly disconnect or not be recognized during startup. Similarly to the mouse and keyboard issue, I would then need re-plugging the monitor for it to work properly.
Screenshots or error messages:
Here is the output of sudo dmesg when the issue happens:
As far as I can see when the mouse and keyboard disconnect, nothing is being printed to the kernel buffer and the only thing that is being printed is when I re-plug the hardware. What I also noticed is that my mouse still has its RGB lights turned on when the random disconnect happens.
What I’ve tried:
- Updating my GPU driver (currently using the latest available version 570)
- Updating my Docking station driver (currently using the latest available version 01.01.00.13)
- Looked in the BIOS for power related settings to USB ports without success
- Disabling USB autosuspend int
/etc/default/grublike so:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1"
Assumptions:
- It could be that the usb autosuspend feature is the cause of this issue in combination of my rather weird “docking station into GPU” setup. Maybe there are some other settings apart from
usbcore.autosuspend=-1which I do not know of and which I could try? - It could also be that the GPU driver is causing issues. I do remember vaguely when I freshly installed Ubuntu and while using the open source drivers that my monitors where recognized without any issues and only when I installed the NVIDIA drivers the issue started happening. Although I cannot say the same for the mouse and keyboard.
Any input is greatly appreciated!
Kind regards,
