Yesterday this usb port works as usual, but today I turned on the notebook and just nothing. I tried to connect usb stick, phone, but nothing. lsusb can’s see it. What can I do, what can I check?

    You could try the little reset hole on the bottom of the laptop.

    I had some weird issues with my z16 none of the usb c ports were working and neither was the usb c dock.

    I think there must have been some static buildup or something that triggered a surge protection or something but for me using the reset pin hole did the trick

    Just have a read up on doing that for your model

    It’s doesn’t wipe the laptop. Just resets the power circuit or something

    You can try to see if lspci sees the USB controller. Next I would try running diagnostics from UEFI, see if you get any errors. Try a bootable USB to verify if it’s a hardware or software issue.

    Any hardware diagnostic failure or failure to boot from it will tell you you need a new system board.
