Hi Greg. Would be great if you could pick up 690eb7dec72a ("HID: logitech: Disable hi-res scrolling on USB") for the next 6.1.y release, as it's fixing a regression I saw multiple people report.

The commit (see below) that was recently merged to mainline and has a proper stable "Cc: <stable@...>" tag, so I guess you scripts will at some point pick it up automatically. But I noticed you updated the stable queue and hour ago and this patch afaics is not in it yet (despite some other patches being in it that were merged later), so I thought: just to be sure send a quick heads up.

Ciao, Thorsten

HID: logitech: Disable hi-res scrolling on USB

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++.
