Abstract:
1. A keyboard/mouse switching controller, comprising: a keyboard connector; a mouse connector; a first group of signal lines and a second group of signal lines coupled to the keyboard connector and the mouse connector respectively, the first group of signal lines for receiving a first group of signals from the keyboard connector, and the second group of signal lines for receiving a second group of signals from the mouse connector; a detector for transmitting a control signal; wherein the control signal is at low level state when a mouse is connected to the keyboard connector or a keyboard is connected to the mouse connector, and the control signal is at high level state when a keyboard is connected to the keyboard connector or a mouse is connected to the mouse connector; a controller coupled to the detector for controlling the first group of signals and the second group of signals output to the detector; a third group of signal lines and a fourth group of signal lines coupled to the controller; and a switching control circuit for coupling the first and second group of signals to the third and fourth group of signal lines respectively when the control signal is at high level state, and for coupling the first and second group of signals to the fourth and third group of signal lines respectively when the control signal is at the low level state.
