The Asus T304UA convertible sports a magnetic detachable keyboard with touchpad, which is connected over USB. Most of the keyboard hotkeys are exposed through the same USB interface as the touchpad. The mapping defined here is the same present in hid-asus, but when using hid-asus to drive this touchpad, we lose the multitouch funcionality. In my experiments, when trying to add mark this USB id with QUIRK_IS_MULTITOUCH in hid-asus, both the keyboard and touchpad stop responding. I would be happy to re-work this series if some guidance is provided on how these kind of mappings should be implemented (is it ok to have vendor-specific mappings in hid-multitouch? how can we keep the mt funcionality if using hid-asus? how can we bing hid-asus only to the to USB interface?). Bellow is the output from usb-devices, where If#=0 exports the keyboard and If#=1 exports the touchpad and media keys.
