Remote USB Disconnection Control After 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 and operational, potentially leading to unmonitored plant operation.
Innovation Solution
An information processing apparatus that detects disconnection of the remote connection and automatically disconnects the USB device from the server based on a stored correspondence relationship, ensuring the USB device is disconnected when the connection is lost or the client hardware fails.
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 USB device can continue to operate, but system security and reliability deteriorate due to unmonitored operation
Solution Approach 1:
The system performs preliminary action by detecting remote connection status and proactively disconnecting USB devices before unmonitored operation can occur. The information processing apparatus monitors the remote connection state and automatically disconnects the USB device server when connection loss is detected, preventing the harmful state of unmonitored USB device operation.
2Reliability
If the information processing apparatus automatically disconnects USB devices upon remote connection loss, then system security improves, but system complexity increases due to additional monitoring and control mechanisms
Solution Approach 1:
The system implements feedback by continuously monitoring the remote connection state and using this information to control the USB device connection state. The information processing apparatus receives feedback about connection status and automatically adjusts the USB device server connection accordingly, creating a closed-loop control system that maintains security without requiring complex manual intervention.
3Device complexity
If manual disconnection of USB devices is required after remote connection loss, then system simplicity is maintained, but productivity decreases due to delayed response and additional manual operations
Solution Approach 1:
The system performs self-service by automatically detecting remote connection loss and autonomously disconnecting the USB device server without requiring manual user intervention. The information processing apparatus monitors its own connection state and takes corrective action, eliminating the need for manual operations while maintaining system simplicity.

AI summary
An information processing apparatus (3) includes a storage unit (13) that stores a correspondence relationship between identification information of a client device (2) connected to the information processing apparatus (3) through remote connection and identification information of a device server (4) to which the information processing apparatus (3) is connected, a disconnection checking unit (21) that detects a disconnection of the remote connection, and a disconnecting unit (22) that disconnects 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.
