Peripheral device and device connection system

A device connection system comprising:

• a device subject to connection;
• a peripheral device that is connected to said device subject to connection;
• and
• a device subject to communication that is separate from said device subject to connection,
• said peripheral device having
• an input/output block that is connected to said device subject to connection,
• a communication block configured to communicate with said device subject to communication, and
• a conversion block configured, if said device subject to communication is a storage device, to convert a storage access command output by said device subject to connection to said input/output block into a communication command that is transferred between said communication block and said device subject to communication,
• said communication block transmitting the communication command generated by said conversion block to said device subject to communication, thereby transferring, with said device subject to communication, one of data that is written by said device subject to connection to said device subject to communication and data that is read from said device subject to communication.

A peripheral device comprising:

• input/output means connected to a device subject to connection;
• communication means for communicating with a device subject to communication;
• and
• conversion means for, if said device subject to communication is a storage device, converting a storage access command output by said device subject to connection to said input/output means into a communication command that is transferred between said communication means and said device subject to communication, wherein
• said communication means transmits the communication command generated by said conversion means to said device subject to communication and
• transfers, with said device subject to communication, one of data that is written by said device subject to connection to said device subject to communication and data that is read from said device subject to communication.
