For those that happen to have a Logitech MX Anywhere 3S mouse connected via Bluetooth, the upcoming Linux 6.19 kernel release is enabling HID++ support for it to enjoy [1]high resolution scrolling and other functionality of the updated protocol.

HID++ is [2]Logitech's addition atop of HID providing extra functionality for mice from high resolution scrolling to onboard profiles, force feedback, and other features depending upon the hardware like RGB effects. [3]Supporting Logitech HID++ on Linux has been a headache and resorting to white-listing products that are known to work properly with the upstream Logitech driver when the HID++ mode is enabled.

The newest Logitech device added to that HID++ permitted list is the Logitech MX Anywhere 3S mouse that has been confirmed to work properly. Independent contributor Dennis Marttinen sent in a patch a few days ago to add the device:

"I've acquired a Logitech MX Anywhere 3S mouse, which supports HID++ over Bluetooth. Adding its PID 0xb037 to the allowlist enables the additional features, such as high-resolution scrolling. Tested working across multiple machines, with a mix of Intel and Mediatek Bluetooth chips."

That patch in turn was merged to Linux 6.19 Git today as part of the [4]HID fixes pull request . In addition to enabling HID++ for the Logitech MX Anywhere 3S, that pull also adds HID ELECOM M-XT3DRBK (018C) support, a HID quirk for the Edifier QR30, and other small HID fixes for the week.

The Logitech MX Anywhere 3S retails for around $90 USD and features a 1000 DPI sensor and 500 mAh battery.
