Abstract
A testing device is capable of simulating plugging and unplugging operations in relation to an USB port of an electronic device. The testing device comprises a processing unit to detect an electrical connection between the testing device and the USB port, and to control an indicator to cycle between a state of recognizability and a state of unrecognizability even though a physical connection to the USB port of the electronic device exists at all times. The state of recognizability indicates the testing device is capable of being recognized by the electronic device, and the state of unrecognizability indicates the testing device is incapable of being recognized by the electronic device. Reading and writing tests are carried out by the testing device each time that recognizability is indicated, to repeatedly test the integrity of the USB port being tested.
