Only one usb port works correctly with cam and remote mouse--how can I repair the other 2 ports?

only one usb port allows sight and sound and cordless mouse...how do I fix the other two usb ports?

I have three usb ports, they all accept usb sticks with pics and videos, and they all light up when plugged in, but only one will give both sight and sound with cam, and that same one is the only one to allow the remote mouse to work....
