Apparatus and method for automatic self-diagnosis using universal serial bus port in digital equipment

An apparatus for digital equipment that is connectable to an external storage unit, the apparatus comprising:

• a processor for searching for a diagnosis file for self diagnosis stored in the external storage unit when the external storage unit is connected;
• and
• an execution unit for, when the diagnosis file is found in the external storage unit, collecting information for at least one item required by the diagnosis file,
• wherein the processor stores the collected information as an output file in the external storage unit.

A digital equipment apparatus, the apparatus comprising:

• an external connection port for connecting to an external storage unit;
• a connection manager for determining if an external storage unit is connected to the external connection port, and if the connection manager determines that an external storage unit is connected to the external connection port, for informing a file processor that the external storage unit is connected to the external connection port;
• the file processor, when being informed by the connection manager that the external storage unit is connected to the external connection port, for searching for a diagnosis file stored in the external storage unit, when the diagnosis file is found in the external storage unit, for sending the diagnosis file to a self diagnosis execution unit, for generating an output file, and for recording information provided by the self diagnosis execution unit in the output file;
• and
• the self diagnosis execution unit for performing self diagnosis of the apparatus based on the diagnosis file received from the file processor, collecting information resulting from the self diagnosis of the apparatus, and providing the collected information to the file manager.
