Hi, The G500s (and the G500 too, I think) does support the "scrolling
acceleration" bit. If I set it, I get around 8 events for each wheel
"click", this is what this driver expects, right? If I understood
correctly, I should try this patch with the
HIDPP_QUIRK_HI_RES_SCROLL_1P0 quirk set for my mouse.
