I need some help with USB ports on my pc. I am not able to use them. It was working fine but some ports were facing connectivity issue. Now the front two ports stopped working. When I connect the pen drive it is not detected. I cannot also use my mouse on the same. I am actually using a laptop. It is easier for desktop to change ports but for laptop it is complicated and costly also. Is there a way to find out which ports are still working.
