Worked on improving input device reliability in the libsdl-org/SDL repository by addressing false-positive input events from the Huion Tablet Kamvas Pro 22. Focused on device driver development using C, the contribution involved implementing a blacklist entry to prevent this tablet from being recognized as a functional joystick across supported platforms. This change enhanced the accuracy of SDL’s input filtering pipeline, ensuring more consistent behavior for both users and OEMs. The work strengthened the baseline for input device recognition by introducing clear, traceable logic to ignore problematic hardware, reflecting a targeted and maintainable approach to cross-platform device management in C.
