Abstract

There is provided a radio communication device including: a host connection interface which is connected to a host apparatus and receives commands input from the host apparatus; a radio communication interface which performs radio communication with another radio communication device; and a controlling unit which controls operation of the host connection interface and the radio communication interface, wherein the controlling unit controls the host connection interface to output device information indicating that the device itself is a peripheral device capable of accessing a storage medium to the host apparatus in response to a command indicating inquiry about information regarding the device.

Claims

1. A radio communication device comprising:

a host connection interface which is connected to a host apparatus and receives commands input from the host apparatus;

a radio communication interface which performs radio communication with another radio communication device; and

a controlling unit which controls operation of the host connection interface and the radio communication interface,

wherein the controlling unit controls the host connection interface to output device information indicating that the device itself is a peripheral device capable of accessing a storage medium to the host apparatus in response to a command indicating inquiry about information regarding the device.

2. The radio communication device according to claim 1,

wherein the device information is information indicating that the radio communication device is a peripheral device capable of accessing a removable storage medium.

3. The radio communication device according to claim 2,

wherein, when connection between the radio communication interface and another radio communication device is not established, the controlling unit controls the host connection interface to output the device information, indicating that a removable storage medium is not attached, to the host apparatus.

4. The radio communication device according to claim 3,

wherein said another radio communication device is a device having a storage medium, and

the controlling unit transfers at least one of commands input from the host apparatus to said another radio communication device via the radio communication interface when connection between the radio communication interface and said another radio communication device is established.

5. The radio communication device according to claim 4, further comprising:

a storage unit which previously stores data defining commands at least either to be transferred or not to be transferred to another radio communication device in a case that connection between the radio communication interface and said another radio communication device is established.

6. The radio communication device according to claim 4,

wherein the controlling unit converts a format of a command from a format corresponding to a first protocol with which the host connection interface complies into a format corresponding to a second protocol with which the radio communication interface complies when the command input from the host apparatus is transferred to said another radio communication device.

7. The radio communication device according to claim 1,

wherein the radio communication interface regularly searches for another radio communication device to be connected while connection between the radio communication interface and another radio communication device is not established.

8. A method of responding to a host apparatus in a radio communication device which is a peripheral device including a host connection interface connected to the host apparatus and a radio communication interface performing radio communication with another radio communication device, comprising the steps of:

receiving a command input from the host apparatus via the host connection interface; and

outputting device information indicating that the radio communication device is a peripheral device capable of accessing a storage medium to the host apparatus via the host connection interface.

9. A program for causing a computer arranged at a radio communication device which includes a host connection interface connected to a host apparatus and a radio communication interface performing radio communication with another radio communication device to function as a controlling unit which controls operation of the host connection interface and the radio communication interface,

wherein the controlling unit controls the host connection interface to output device information indicating that the device itself is a peripheral device capable of accessing a storage medium to the host apparatus in a case that a command indicating inquiry about information regarding the device is input from the host apparatus via the host connection interface.
