My Dell XPS 13 Ultrabook can't detect Cypress Trackpad correctly.
It detected as 'ImPS/2 Generic Wheel Mouse'.
'Cypress Trackpad' works just basic function not fully.
The trackpad(touchpad)'s L-button and R-button works and scrolling and dragging work not perfectly.
Tapping work not perfectly, either.
For tapping, I should tap and hold the tapping for about 1sec. and then, it recognize tapping.

In launchpad exists a bug with this problem:

We do not have dedicated Cypress touchpad support in kernel at this time...

Cypress touchpad has been added to Lenovo laptops now, I have an ideapad U400 and I have the same problem.

Comment 5 emailgrant 2012-11-09 00:26:20 UTC

Is Cypress touchpad support in the kernel yet?

It is now in the upcoming 3.9.x.

Comment 7 emailgrant 2013-04-19 23:27:52 UTC

And it works great! :)

It really does for you? Using no specific config here and it "feels" slow and it doesn't react on taps, only the click-area can be used.

Care to share your config (if you have specific one)?

Comment 9 emailgrant 2013-04-20 00:39:15 UTC

I actually have no config at all.  It just feels better to me.  I hate taps. :)

The new versions of kernel solve this problem!
