ABSTRACT:
A device is connectable to a computer through USB interface. The device includes a mode switching section configured to switch the device to one of a first mode and a second mode in which an access from the computer to a USB storage device is permitted and prohibited, respectively. When a standard data string is received and the device is in the first mode, the device accesses the physical storage area of the data storage section. When the standard data string is received and the device is in the second mode, the device transmits a pseudo response to the computer, the pseudo response indicating that no storage medium is mounted to the data storage section. When a particular data string is received, the device accesses a file through a file system provided in the device.
