"HID: logitech: Disable hi-res scrolling on USB" says: " On some Logitech mice, such as the G903, and possibly the G403, the HID events are generated on a different interface to the HID++ one. If we enable hi-res through the HID++ interface, the HID interface wouldn't know anything about it, and handle the events as if they were regular scroll events, making the mouse unusable. Disable hi-res scrolling on those devices until we implement scroll events through HID++. " This bug is about tracking re-enabling hi-res scrolling support for G903 mice.
Hey there thanks for the patch in the other report, it at least restored sane functionality in my case. I'm "working" as a support staff/forum moderator on the Arch Linux boards and there where a bunch of people that mentioned to still be having issues/the high res enablement in general not really leading to the results they want/generally unexpected scrolling behaviour. https://bbs.archlinux.org/viewtopic.php?id=282852 So I'm asking how much of an issue it would be to consider my original proposal in https://bugzilla.kernel.org/attachment.cgi?id=303559 of providing a module parameter to control whether high res is enabled in the first place or not. Since this is somewhat related to the original report, I surmised to add this here, sorry if this should rather be a report on it's own.

I would be against adding any module parameter to work-around driver bugs. If there are still problems with hi-res scrolling on particular Logitech devices with an updated kernel, you should consider reporting those to the linux-input list, or filing a bug in this bugzilla. The bug you mentioned has details on what information to provide.
This also happens with MX Master 3 (running through USB Unifying receiver)
