Worked on enhancing the reliability of USB HID descriptor parsing in the microsoft/mu_plus repository, focusing on embedded systems and firmware development using C. Addressed a critical stability issue by implementing a defensive check in the UsbGetFullHidDescriptor function to detect and handle zero-length descriptor headers, thereby preventing infinite loops caused by malformed USB descriptor data. This targeted bug fix reduced the risk of system hangs and excessive CPU usage, directly improving the robustness and maintainability of driver code. The contribution aligned with broader goals of system reliability, ensuring that USB peripherals interact safely and predictably within the firmware environment.
