This is a note to let you know that I've just added the patch titled HID: multitouch: Add quirk for Logitech Bolt receiver w/ Casa touchpad to the 6.6-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: hid-multitouch-add-quirk-for-logitech-bolt-receiver-.patch and it can be found in the queue-6.6 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit dc79a766aa6e5972f763cc185bd5084a52c6b80c Author: Kenneth Albanowski <kenalba@xxxxxxxxxxxx> Date: Fri Oct 4 10:24:29 2024 -0700 HID: multitouch: Add quirk for Logitech Bolt receiver w/ Casa touchpad [ Upstream commit 526748b925185e95f1415900ee13c2469d4b64cc ] The Logitech Casa Touchpad does not reliably send touch release signals when communicating through the Logitech Bolt wireless-to-USB receiver. Adjusting the device class to add MT_QUIRK_NOT_SEEN_MEANS_UP to make sure that no touches become stuck, MT_QUIRK_FORCE_MULTI_INPUT is not needed, but harmless. Linux does not have information on which devices are connected to the Bolt receiver, so we have to enable this for the entire device.
