How to make a wired serial touchpad work in 12.04 LTS?

I have a Cirque serial touchpad that I would like to use, even though the usb mouse works fine.

Checked software center, it shows these are installed: X.Org Mouse input driver, X.Org VM mouse driver, Synaptics touchpad driver, Simple Directmedia Layer, X11 utilities.

I powered down, unplugged the usb mouse, plugged in the serial touchpad and rebooted, the touchpad does not respond. On the Windows computer the regular mouse driver ran the touchpad, no special driver was required.

This is not critical but I like the touchpad and a new usb pad costs $40 or $50! Have not found a question that covers this situation. Any help appreciated.
