    Is it supposed to work with anything other than a mouse?

          By USB key you mean what, exactly?

          A flash drive, or a license dongle, or something else?

              You may have some kind of incompatibility? Like flash drive is too big, the file system format is unsupported, maybe even the interface USB 3 vs USB 2 is some issue?

              What is the model of this device? Is there any specification about what kind of drives it supports?

                  Then change that USB controller / host IC, and look hard between it and the port for damages like the protection diodes.
