    What speaker? What kind of USB socket is not working? Where are the photos? What to do? If you are "green" do nothing yourself. There are some topics on Elektroda regarding USB replacement ... Just look for it.

    I understand that we are talking about USB - type A. There is nothing else but to unscrew the "speaker" and check if the socket / PCB connections are not damaged. Of course, start by replacing the cable with another (functional) one.
