[FIXED] t480: usb port stopped work

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

IT'S WORKED! I don't know really why, but thank you very much, I already scared about it, but right now port is working!

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.
