# OpenMouse: reconstructing Kysona M600 V2 mouse control

> OpenMouse implements a macOS client for the Kysona M600 V2 mouse from recovered HID control messages. The author derived framing and checksums from the vendor's Windows library, refined the protocol with USB captures, and wrote Swift code for settings such as DPI, report rate and button mapping.
