3. Usage Page
4. Usage
The first two can easily be found in your keyboard's `config.h` in the keyboard's main directory under `VENDOR_ID` and `PRODUCT_ID`. **Usage Page** is **`0xFF60`** and **Usage** is **`0x0061`**.
The first two can easily be found in your keyboard's `config.h` in the keyboard's main directory under `VENDOR_ID` and `PRODUCT_ID`.
The final two can be overridden in your keyboard's `config.h` in the keyboard's main directory by redefining the values: `#define RAW_USAGE_PAGE 0xFF60` and `#define RAW_USAGE_ID 0x61`.
By default, **Usage Page** is `0xFF60` and **Usage** is `0x61`.
