PROBLEM TO BE SOLVED: To provide a method enabling an operation without a driver of a key chain storage device using an existing operating system and used for activating automatic execution and a private command interface. SOLUTION: A peripheral device of a host computer includes a microcontroller and two virtual devices. The first virtual device passes, to the microcontroller, commands of a first command set from an arbitrary user of the host computer and also commands of a second command set from only privileged users of the host computer. The second virtual device passes, to the microcontroller, commands of the second set from the arbitrary user of the host computer. The two virtual devices are implemented as separate physical devices, and the second device is connected to an interface to the host computer only if the user is not privileged.
