Human Interface Device Peripheral Control via MCU Without OS Drivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-media input devices require operating system (OS) dependent drivers to function, limiting their use and functionality across different OS platforms and making them vulnerable to manipulation by malicious actors.
Innovation Solution
A system-integrated approach that utilizes an out-of-band communication pathway via a micro-control unit (MCU) to receive requests from human interface devices, bypassing the need for OS drivers, allowing direct control of peripheral devices through an inter-integrated circuit (I2C) bus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If OS dependent drivers are used to enable multi-media input device functionality, then the devices can control peripheral functions, but the system becomes vulnerable to manipulation and lacks portability across different operating systems
Solution Approach 1:
The patent introduces a driverless multi-media input device that acts as an intermediary between the user and the operating system. The device includes a controller that processes input signals locally and generates control signals for peripheral devices without requiring OS drivers. This intermediary architecture enables the device to function across different operating systems while maintaining security by bypassing the vulnerable driver layer.
Solution Approach 2:
The patent segments the functionality of the multi-media input device into independent components: an input signal receiver, a local controller for processing signals, and a control signal generator. This segmentation allows the device to operate autonomously without relying on OS drivers, thereby improving both security and cross-platform compatibility while maintaining full functionality.
2Ease of operation
If driver-based control is implemented, then peripheral device functionality can be accessed, but the system complexity increases and ease of operation decreases
Solution Approach 1:
The patent implements self-service functionality within the multi-media input device itself. The device includes an integrated controller that automatically processes input signals and generates appropriate control signals for peripheral devices without requiring external driver software. This self-service capability simplifies operation for users while reducing overall system complexity by eliminating the driver layer.
3Productivity
If conventional USB communication is used for input devices, then standard connectivity is maintained, but direct control of peripheral devices without CPU involvement is not possible
Solution Approach 1:
The patent introduces a new communication dimension by enabling direct control signals to bypass the traditional USB-CPU-OS driver pathway. The multi-media input device directly generates and transmits control signals to peripheral devices, creating a parallel control channel that operates independently of the conventional communication architecture. This dimensional change enables efficient direct control while maintaining compatibility with existing USB connectivity standards.

AI summary
A system-integrated solution for input/output device extended-control without operating system driver involvement is provided. In examples, systems and methods include receiving an out-of-band request from a human interface device, receiving an in-band request from the human interface device, and sending a signal directly to a peripheral device, via a micro-control unit, to honor the out-of-band request. In examples, the out-of-band request is received via an inter-integrated circuit.
