Abstract
A USB controller is provided between a personal computer main unit and various devices. By providing the USB controller with a switch part for temporarily cutting a current flowing between the USB controller and the personal computer main unit, the circuit is connected or interrupted. With the configuration, when a new device is connected, by sequentially turning on and off a switch in the switch part, an operation similar to pull-out and insertion of a connector or resetting of a system can be executed, so that the newly connected device can be made usable immediately.
