// Reference: https://docs.microsoft.com/en-us/windows-hardware/design/component-guidelines/touchpad-configuration-collection#selective-reporting-feature-report
// Details:
// The two rightmost bits control the touchpad status
// In order, they are:
// 1. LED off + touchpad on/LED on + touchpad off
// 2. Clicks on/off
// So, the options are:
// 0x00 LED on, touchpad off, touchpad click off
// 0x01 LED on, touchpad off, touchpad click on
// 0x02 LED off, touchpad on, touchpad click off
// 0x03 LED off, touchpad on, touchpad click on
