UBS Port not functioning
The right side (facing the display) UBS port has already become non functional.
It seems like a hardware issue.
I would still suggest the following tests before you visit a service center.
- Open the Konsole application and run
udevadm monitor,now connect a functional USB device such as a pendrive/keyboard/mouse and monitor the output
If you see some output immediately after connecting the USB device then the slot is fine and OS could detect it.
If your output remains unchanged then you may have a damaged USB port.
Optionally, you can try repeating the same test with the other USB port to confirm.
