+  * sets the USB polling rate in milliseconds for the keyboard, mouse, and shared (NKRO/media keys) interfaces
 * `#define F_SCL 100000L`
   * sets the I2C clock rate speed for keyboards using I2C. The default is `400000L`, except for keyboards using `split_common`, where the default is `100000L`.
