Abstract

An apparatus, a method, and a system for controlling communications between a host device and a USB device. The apparatus includes a controller to perform an operation for communication between a first device and a second device, and a first processor to selectively stop the operation of the controller according to information indicating a status of the communication between the first device and the second device. Thus, the USB device can perform a unique function even when the USB device is connected to the host via USB.

Description

[0001] References to related applications [0002] This application claims priority from Korean Patent Application No. 2007-31732 filed in the Korean Intellectual Property Office on March 30, 2007, the disclosure of which is incorporated herein by reference. technical field [0003] Aspects of the present invention relate to an apparatus, method and system for controlling communication between a host device and a USB device, and more particularly to a USB device and its corresponding method, which can be used even when no operation is being performed on the host communication or charging process over USB without physically cutting off the connection with the host device. Background technique [0004] The Universal Serial Bus (USB) was created to standardize the interface between computers and computer peripheral devices such as a mouse, keyboard, printer, modem, or speakers. Communication over USB speeds up the installation and removal of complex adapters such as drives. F...
