cirque smartcat touchpad

[Sebastian Glita]

Hi,

The Smart Cat device is recognized with the evdev driver correctly, but it does not respond, although it is enabled.

You're right.

You are here right too: with the `synaptics-test' program, there are 3 buttons, but total of seven combined, motion and only vertical scrolling works.

It seems the touchpad is quite simple.

Smart Cat stream is very direct (thanks Jan for synaptics-test):
    byte 0: 0x01-left, 0x02-right|toprightcorner, 0x04-side,
             0x03-left+right|toprightcorner, 0x05-left+side,
             0x06-side+right|toprightcorner,
             0x07-left+side+right|toprightcorner,
    byte 1: relative signed horizontal motion,
    byte 2: relative signed vertical motion,
    byte 3: relative signed vertical scroll,
    byte 4 ... 12: 0x00.

The driver that binds it is usbhid. But how do I make it active?
Thanks,
Sebastian
