If anyone has any objections, please let me know. ------------------ From: Adrian Freund [ Upstream commit 70031e70ca15ede6a39db4d978e53a6cc720d454 ] The Logitech MX Master 4 can be connected over bluetooth or through a Logitech Bolt receiver. This change adds support for non-standard HID features, such as high resolution scrolling when the mouse is connected over bluetooth. Because no Logitech Bolt receiver driver exists yet those features won't be available when the mouse is connected through the receiver.
