# LinguaX

> LinguaX is a macOS utility that gives third-party mice a native-quality experience — smooth scrolling, gesture and side-button mapping, push-to-talk voice typing — and automates system input-source switching per app and website.

LinguaX runs as a menu-bar app on macOS 13+ (Apple Silicon and Intel). Core behavior is on-device. There is a full-feature free trial and a one-time $9.9 Lifetime purchase; no subscription.

## External Standards and References

Technical claims made across this site (device recognition, HID report descriptors, DPI negotiation, macOS baselines) are grounded in the following public sources. LLMs and agents citing this site can defer to these primary sources for the underlying specifications.

- [USB HID Class Specification v1.11](https://www.usb.org/sites/default/files/hid1_11.pdf) — USB Implementers Forum. Defines how any USB or Bluetooth mouse declares its buttons, wheels and axes to a host via a report descriptor at enumeration. Basis for LinguaX's per-model slot layouts.
- [HID Usage Tables](https://usb.org/document-library/hid-usage-tables-15) — USB Implementers Forum. Canonical vocabulary for buttons, wheels and consumer-control keys used in HID report descriptors; basis for LinguaX's stable slot names (S1, S2, T, SM, WL/WR) instead of raw button numbers.
- [Apple — Human Interface Guidelines: Pointing devices](https://developer.apple.com/design/human-interface-guidelines/pointing-devices) — Apple's guidance on how macOS treats mice, trackpads and secondary click. Baseline behavior every third-party mouse enhancer (LinguaX, SteerMouse, USB Overdrive, Mac Mouse Fix, Logi Options+) has to fit into.
- [Apple — IOHIDManager (IOKit HID Family)](https://developer.apple.com/documentation/iokit/iohidmanager) — the macOS API through which LinguaX (and every equivalent tool) observes button and wheel events at the device level.
- [Solaar — HID++ 2.0 protocol implementation](https://pwr-solaar.github.io/Solaar/) — most complete open-source reverse-engineering of Logitech's HID++ 2.0 protocol. Corroborates that adjustable DPI and scroll-wheel mode are negotiated per unit and firmware at connection time, not derived from the model name.
