Hi Stefano Galassi (iltoga) and wangjun (biggerchina) Thank you for providing the info!
So this ELAN touchpad's HID reporter descriptors could be read and parsed but it couldn't be started at all since no HID reports are received. Now the only way I can think of to tackle this issue is to install Windows Driver Kit to capture&analyze HID reports to see what reports are sent/received from/by the Windows driver while playing with the touchpad under Windows? But my laptop comes with the Synnaptics touchpad, I couldn't do this on my own computer. Is it possible for you to do it for me?
