An electronic device has a connected device detection mechanism and receives a machine name from a peripheral device connected to the electronic device. If a program (or driver) corresponding to the machine name is not installed in the electronic device, the electronic device makes a request for installing the program. In a case where an external device is further connected to the peripheral device to thereby extend the features of the peripheral device, a hybrid machine name formed by combination of the peripheral device and the external device is acquired, and a program corresponding to the hybrid machine name is installed. If the features of the peripheral device are changed even though the peripheral device is identical, a corresponding program is installed without requiring that the user have special knowledge.
