USB Device Server Disconnection After Remote Connection Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional monitoring and control systems face risks when a client computer hardware fails or a remote desktop connection is lost, as the USB device remains connected, potentially allowing unauthorized operation of the system.
Innovation Solution
An information processing apparatus that stores a correspondence relationship between client devices and device servers, detecting disconnections and automatically disconnecting the USB device server when a remote connection is lost or fails, using a processor to manage these connections based on stored relationships.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the USB device remains connected to the information processing apparatus after remote connection loss, then the system maintains continuous device availability, but the system security and operational reliability deteriorate due to unauthorized operation risks
Solution Approach 1:
The system performs preliminary action by detecting remote connection status changes and proactively disconnecting USB devices before unauthorized operations can occur. The information processing apparatus monitors connection status and automatically executes disconnection when remote connection is lost, preventing potential security incidents rather than responding after they occur.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring remote connection status and using this information to control USB device connectivity. When the remote connection status changes from connected to disconnected, the system receives feedback and automatically adjusts the USB device connection state accordingly, creating a closed-loop control system that maintains security.
2Reliability
If the system automatically disconnects USB devices upon remote connection loss, then system security improves, but the system complexity increases due to additional monitoring and control mechanisms
Solution Approach 1:
The system merges the remote connection monitoring function with the USB device connection control function into a single integrated mechanism. The information processing apparatus combines these previously separate functions, using the same connection status detection to control both remote access and USB device access, thereby reducing overall system complexity while maintaining security.
Solution Approach 2:
The system implements self-service by enabling the information processing apparatus to automatically monitor its own connection status and autonomously execute disconnection actions without external intervention. The apparatus manages its own security by detecting remote connection loss and automatically disconnecting USB devices, eliminating the need for separate manual monitoring or additional control systems.

AI summary
An information processing apparatus includes a memory that stores a correspondence relationship between identification information of a client device connected to the information processing apparatus through remote connection and identification information of a device server to which the information processing apparatus is connected, a processor coupled to the memory and the processor configured to: detect a disconnection of the remote connection, and disconnect a connection between the information processing apparatus connected through the remote connection from the client device that has requested the disconnection and the device server based on the correspondence relationship when the disconnection is detected.
