 > **MX Master 4 smooth scrolling** is disabled in the shipped descriptor: the hardware does not respond correctly to the HID++ configuration used on MX Master 2S / 3S. Regular scroll wheel and SmartShift work normally; only sub-tick smoothing is unavailable. Re-enable yourself by setting `"smoothScroll": true` in `devices/mx-master-4/descriptor.json` if your unit behaves differently; if it works we will promote the default.
