# IPI STAY FLY Driver: reconstructing mouse configuration over HID

> IPI STAY FLY Driver reconstructs mouse configuration in a Windows app using reverse-engineered 16-byte HID frames. It exposes DPI, polling, button and sensor settings, documents a frame checksum, and includes a WebHID capture extension plus protocol notes for ATK FIERCE X.
