PURPOSE: A method capable of controlling data of an additional storing device by connecting to a personal computer port(USB), a device for controlling data of card type built-in personal computer(USB), and device for controlling data of integrated personal computer port(USB) are provided to move, store, or search data stored in an HDD, a CD-ROM, an FDD to other PC or PDA through a PC port(USB) with other PC or PDA by inserting a card type built-in PC port(USB) data control device or a PC integrated type PC port(USB) data control device in a PC or a PDA. CONSTITUTION: When a power source of a PC main body is turned on, an external computer PC port(USB) connection unit(17) is operated with a PC port(USB) data conversion unit(14) by a PC port(USB) interface switching unit(13) at a non-contacted state. At this, time, a computer device connected to the connection unit(17) is not recognized. When a power source of a PC main body is turned off, the external computer PC port(USB) connection unit(17) is operated by the PC port(USB) interface switching unit(13) at a contacted state, a computer which is operated at an exterior is connected through a connection cable. At this time, a power source is applied to the PC port(USB) data conversion unit(14) and an IDE connector connection type built-in auxiliary memory connection unit(15), and an external computer may be connected to the auxiliary memory. Thus, data may be exchanged between the external computer and an internal auxiliary memory.
