When a peripheral device is connected to a host apparatus for the first time, an easy and secure installation of the driver of the peripheral device into the host apparatus is made possible. A printer 102, and a storage 103 storing a driver 104 for the printer 102 and an installer thereof, which function on a PC 200 are connected, as USB devices 111, 112, to a USB hub 110. An installation flag 105 records a value indicating an installation state of the driver 104. When the PC 200 is connected to the USB hub 110, if the value of the installation flag 105 indicates "non-installed", the PC 200 is so controlled as to make access only to the storage 103. If the value of the installation flag 105 indicates "already installed", the PC 200 is so controlled as to make access to the storage 103 and the printer 102.
