Abstract
A system which serves both as a host and a device cannot be realized with a single connector due to the constitution of hardware in the prior art. The prior art system only detects the existence of a device and cannot distinguish between a host and a device while a power source is turned on and switch its function. The information processing apparatus of the present invention separates the data lines of a host communication controller and the data lines of a device communication controller and activates the selected controller by means of selecting the data lines of the controllers and means of determining which is connected to a connector, a host or a device.
