It reconnects again after a few seconds, but it's an incredibly jarring experience since it will just cut out in the middle of mouse operations. This patch ignores querying the battery and avoids disconnects. This bug is reported here: - https://bugzilla.kernel.org/show_bug.cgi?id=204589 - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1834085 It looks like a similar approach (disabling battery checking) was also suggested for the Apple Magic Mouse before a custom driver was created: https://bugzilla.kernel.org/show_bug.cgi?id=103631 Signed-off-by: Nimish Gåtam Signed-off-by: Jiri Kosina --- diff --git a/drivers/hid/hid-input.c b/drivers/hid/hid-input.c index 851ee86eff32a..96659a7fb4634 100644 --- a/drivers/hid/hid-input.c +++ b/drivers/hid/hid-input.c @@ -358,6 +358,9 @@ static const struct hid_device_id hid_battery_quirks[] = { { HID_BLUETOOTH_DEVICE(USB_VENDOR_ID_APPLE, USB_DEVICE_ID_APPLE_ALU_WIRELESS_ANSI), HID_BATTERY_QUIRK_PERCENT | HID_BATTERY_QUIRK_FEATURE }, + { HID_BLUETOOTH_DEVICE(USB_VENDOR_ID_APPLE, + USB_DEVICE_ID_APPLE_MAGICTRACKPAD), + HID_BATTERY_QUIRK_IGNORE }, { HID_BLUETOOTH_DEVICE(USB_VENDOR_ID_ELECOM, USB_DEVICE_ID_ELECOM_BM084), HID_BATTERY_QUIRK_IGNORE },
