I bought a small touchpad to stick on top of the keyboard, and it works fine on the windows computer, but not on my ubuntu desktop.

I mean, when I do "xinput list" it shows the following:

? Virtual core pointer                          id=2    [master pointer  (3)]
?   ? Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
?   ? PIXART USB OPTICAL MOUSE                  id=8    [slave  pointer  (2)]
?   ? Logitech USB-PS/2 Optical Mouse           id=11   [slave  pointer  (2)]
?   ? Microsoft Wired Keyboard 600              id=13   [slave  pointer  (2)]
?   ? Macintosh mouse button emulation          id=14   [slave  pointer  (2)]
?   ? Cirque Corporation 9925 AG Touchpad       id=15   [slave  pointer  (2)]
? Virtual core keyboard                         id=3    [master keyboard (2)]
    ? Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ? Power Button                              id=6    [slave  keyboard (3)]
    ? Power Button                              id=7    [slave  keyboard (3)]
    ? No brand SP04-A1                          id=9    [slave  keyboard (3)]
    ? Elite Silicon USB Audio Device            id=10   [slave  keyboard (3)]
    ? Microsoft Wired Keyboard 600              id=12   [slave  keyboard (3)]

The Cirque Corporation touchpad (I'm assuming that's the component name) is the touchpad. Is there anything I'm missing?
