- The author uses a Logitech G502 mouse due to its ergonomics and customizable buttons, but dislikes the official G HUB software for being bloated and lacking Linux support.
- To avoid G HUB, the author stores button mappings on the mouse's onboard memory, mapping extra buttons to unused function keys (F13-F24), then uses Karabiner-Elements to translate those into shortcuts via a plain text JSON file.
- When upgrading to a newer G502 X, the author used the open-source tool 'opengcontrol' to migrate configurations, but it lacked support for their devices, so they extended it with Claude's help to add device definitions, profile cloning, battery readouts, and fixes.
- Claude assisted in reverse-engineering the mouse's memory layout and checksums, enabling scriptable control over profiles and battery status, leading to a menubar widget for battery monitoring.
- The integration allows an agent to edit both the mouse's firmware profiles and OS remappings coherently via CLI and plain text, making the entire setup machine-readable and improvable without proprietary software.
