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 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.
