Abstract
A testing device for a USB I/O board includes USB plugs connected to the USB I/O board, a connector connected to the USB I/O board, an indication module, and a testing module including data output terminals connected to the USB plugs, data reception terminals connected to the connector, and indication terminals connected to the indication module. The testing module sends a testing signal to the USB I/O board via the data output terminals, and receives the testing signal from the USB I/O board via the data reception terminals. The testing module compares the testing signal to a threshold signal stored in the testing module. If the testing signal and the threshold signal are not substantially the same, the testing module generates an alarm signal to drive the indication module via the indication terminal. The indication module indicates the USB I/O board is abnormal.
