RE: ASUS G752VS Touchpad does not work

Hi Chris,

His Interrupt is fasteoi, I guess it's kind of level trigger.

I remember that you debug for an Acer PTP which cause touchpad no function sometimes.
And it works fine after interrupt modified to edge trigger.

What's your comment?

Thanks	KT

I read the whole threads. It's normal there's no interrupt observed 
if using elan_i2c driver. It should use hid-multitouch.

I would like to know if there's any interrupts observed when it load 
hid-multitouch driver instead of elan_i2c driver.

Something noted here, on my G752VSK the input device shows as 
ELAN1200 not ELAN1203. Although I think it should make no difference, 
just to note that my machine maybe a little different from the bug reporter's.

Can you provide information Chris asked?
His G752 uses a slightly different touchpad so more information is 
needed.

Thanks!
