Hello,
I would like to have some help to add support for multitouch support for
Asus T300LA TouchPad.
In the current state, both keyboard and touchpad are binded to
hid-generic driver because the USB VID:PID is not set in hid-asus
driver. So keyboard and touchpad are partially working (some keyboard
keys missings, touchpad only works with one finger).

The mouse descriptor seems very weird to me and I cannot understand how
am I suppose to enable multitouch from it.
Does any one have an idea ?
