$ uname -r 3.16.0-4-amd64 $ grep CONFIG_HID_APPLE /boot/config-3.16.0-4-amd64 CONFIG_HID_APPLE=m CONFIG_HID_APPLEIR=m $ lsmod | grep hid_apple hid_appleir 12724 0 hid_apple 12596 0 hid 102264 4 hid_generic,usbhid,hid_appleir,hid_apple $ lsusb -d 05ac:0231 Bus 005 Device 020: ID 05ac:0231 Apple, Inc. Internal Keyboard/Trackpad \ (MacBook Pro 4,1) (ISO) Now, APPLE_IGNORE_MOUSE only appears in drivers/hid/hid-apple.c:28, where it is #define'd but never referenced, making it hard for me to see the connection. However, while looking for uses of USB_DEVICE_ID_APPLE_WELLSPRING2_ISO, I found hid_mouse_ignore_list defined in drivers/hid/hid-core.c:2358 and referenced after the switch statement in drivers/hid/hid-core.c:2482 as an argument to hid_match_id(), which is executed only if the device's type in question is of HID_TYPE_USBMOUSE. If I had to venture a guess here I'd say that that is never the case. Cheers, Christian
