Elantech PS/2 touchpad stops responding after a suspend/resume in Asus X450LCP

Hi guys,

after putting my Asus in the nomux list, it stops to work after I close and reopen my laptop(suspend/resume). Do you have any idea what's going on?

I tried to get some additional information in dmesg before and after it stops working, but it seems that I don't give any useful information there.

Thanks,
    Marcos
