Abstract
A keyboard controller supports both a first keyboard/mouse interface and a second keyboard/mouse interface. Data is routed between the first keyboard/mouse interface and a first host interface when the first host interface is active. Data is routed between the first keyboard/mouse interface and a first shell when a second host interface is active. The first shell provides compatible connection between the first keyboard/mouse interface and the second host interface. Data is routed between the second keyboard/mouse interface and the second host interface when the second host interface is active. Data is routed between the second keyboard/mouse interface and a second shell when the first host interface is active. The second shell provides compatible connection between the second keyboard/mouse interface and the first host interface.
