Problems solved by technology

[0014] In this procedure, in the case of an information processing device operating as a server without an input device such as a mouse or a keyboard connected, there is a problem that the OS cannot be notified that the USB device has been removed.
[0015] In addition, when a screen display unit for displaying the connection status is not connected as in Patent Document 1, and when the screen display unit for display is provided but the application is operated in a state where the application is displayed on the entire screen, the same The OS cannot be notified of the detachment, so there is a problem that it cannot be visually recognized that it has become a detachable state.

Embodiment 1

[0035] figure 1 It is a configuration diagram of an information processing device equipped with a USB port according to the first embodiment. The information processing device 1 is constituted by, for example, a general-purpose PC.

[0036] exist figure 1 Among them, the information processing device 1 is equipped with: a USB port 13, which is connected to an external USB device 2; an input unit 15, which requests to remove the USB device from the USB port 13; The connection processing state when USB port 13 is connected and the processing state of taking off when taking off are controlled; Input and output control hub (I / O ControlHub) 12, input USB port 13 and the presence or absence signal of the connection of USB device 2, will come from The take-off request signal of the input unit 15 is sent to the USB device connection control unit 11, and receives the output from the USB device connection control unit 11, and outputs the connection processing status and the removal pr...

Embodiment 2

[0056] refer to Figure 4 and Figure 5 Embodiment 2 will be described. Figure 4 In Example 2 shown, the same reference numerals are assigned to the same parts as in Example 1, and description thereof will be omitted. The difference between Embodiment 2 and Embodiment 1 is that, in the case where the USB device 2 is a removable USB memory, the following functions are added to the information processing device 1: a USB enclosure (enclosure) 16 for accommodating the USB memory is provided, Therefore, it has the security function of protecting the information of the USB memory.

[0057] Figure 4 is a configuration diagram of an information processing device 1 provided with a USB case 16, Figure 5 It is a plan view or a side view of an example of the structure of a portion of the USB case 16 .

[0058] Such as Figure 4 and Figure 5 As shown, the USB housing 16 is equipped with: a mechanical shutter (shutter) 16b for opening and closing the attachment and detachment por...

Abstract

The invention provides an information processing device having USB ports, which can easily visually identify the connecting states of USB devices including the state of applicability or the state of being capable of being removed and remove USB devices having USB ports when no output device such as a mouse or a keyboard is connected. In the embodiments, the information processing device comprises USB ports, an input part for inquiring removing performances of a USB device from the USB ports, a USB device connecting control part for performing the connecting processing state operation of the USB device during a connecting state with the USB port and further performing the removing processing state operation of the USB device during a removed state, an input output control hub for sending signals showing whether the USB port and the USB device is connected or not to the USB device connecting control part, as well as removing inquiring signals from the input part, and receiving the output from the USB device connecting control part and further output the connecting processing state as well as the removing processing state of the USB device, and a display part displaying the output of the input output control hub.

Description

[0001] This application is based on and benefits from prior Japanese Patent Application No. 2011-37595, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to an information processing device equipped with a USB port. Background technique [0003] In recent years, peripheral devices (herein referred to as USB devices) of information processing devices such as PCs (Personal Computers) equipped with USB (Universal Serial Bus: Universal Serial Bus) ports are increasing. [0004] Such USB is characterized in that it can communicate at high speed and with high reliability, is easy to plug and play, is a small connector, and can save space for power supply, so it is also used in external applications. High-speed devices such as HDD (Hard Disk Drive) and flash memory (FlashMemory), low-speed devices such as mouse / keyboard, etc. [0005] After these USB devices are connected to a host device such as a PC, after a...
