Abstract:
A method for controlling a bus is provided. In particular, an external device may be interfaced with a bus internal to a computer system. The method involves detecting when a device is coupled to the bus, and driving signals onto the bus in response to detecting the device being coupled to the bus. Alternatively, when the external device is not coupled to the bus, the signals are blocked, disabled, or otherwise prevented from being delivered onto the bus.
