Abstract:
1. An information processing system comprising: a host device that transmits an order according to a USB (Universal Serial Bus) standard; and an information processing terminal that responds to the order, which is transmitted from the host device, according to the USB standard, characterized in that the information processing terminal includes: a storing unit that stores data; a first operation unit that receives a first user input indicating a first instruction for processing; a receiving unit that receives the order transmitted from the host device according to the USB standard; an operation-mode switching unit that switches, when the receiving unit receives an operation mode switching order for ordering the information processing terminal to switch an operation mode of the information processing terminal itself in a state in which the information processing terminal is connected to the host device, the operation mode of the information processing terminal to a first operation mode, a second operation mode, or a third operation mode according to the operation mode switching order; a first processing unit that executes, in the first operation mode, the first instruction for processing indicated by the first user input using the data stored in the storing unit and does not execute, in the second operation mode and in the third operation mode, the first instruction for processing indicated by the first user input, the first processing unit performing management of a file system of the storing unit while in the first operation mode; and a first outputting unit that outputs a result of executing the first instruction for processing by the first processing unit, and the host device includes: a second operation unit that receives a second user input indicating a second instruction for processing; a transmitting unit that transmits, when the host device is instructed to switch the operation mode of the information processing terminal, an operation mode switching order for ordering the information processing terminal to switch the operation mode to an instructed operation mode to the information processing terminal according to the USB standard, the instructed operation mode corresponding to the first operation mode, the second operation mode, or the third operation mode; a second processing unit that executes the second instruction for processing indicated by the second user input, when the information processing terminal is switched to the second operation mode according to the operation mode switching order transmitted by the transmitting unit, the second processing unit using the data stored in the storing unit to execute the second instruction for processing and the second processing unit performing management of the file system of the storing unit while the information processing terminal is in second operation mode; and a second outputting unit that outputs a result of executing the second instruction for processing by the second processing unit; the second processing unit executing the second instruction for processing indicated by the second user input, when the information processing terminal is switched to the third operation mode according to the operation mode switching order transmitted by the transmitting unit, the second processing unit using the data stored in the storing unit to execute the second instruction for processing and the first processing unit of the information terminal performing management of the file system of the storing unit while the information processing terminal is in the third operation mode.
