Say Y here if you have an Apple USB BCM5974 Multitouch

The BCM5974 is the multitouch trackpad found in the Macbook

Air (JAN2008) and Macbook Pro Penryn (FEB2008) laptops.
|

|

It is also found in the IPhone (2007) and Ipod Touch (2008).

This driver provides multitouch functionality together with

the synaptics X11 driver.

The interface is currently identical to the appletouch interface,

* The Wellspring trackpad, like many recent Apple trackpads, share

||||
* device, resulting in trackpad malfunction under certain

* circumstances. To get around this problem, there is at least one
|

* example that utilizes the USB_QUIRK_RESET_RESUME quirk in order to
|
||||
* recieve a reset_resume request rather than the normal resume.
|
