Re: Elantech Touchpad Woes - Support for Elantech touchpads over i2c/SMBus still possibly missing

Hi all,

I have a ASUS Zenbook UX430U with the same problem. I am heading to 
BSDCan (and the FreeBSD Dev Submit as a guest) this week and could spend 
some time working on this in the hacker lounge. That said, I am new to 
FreeBSD driver code, so I could use some guidance to help me along. 
Anyone headed to the conference that might be able to lend me a hand?
