touchscreen on USB


Is it possible to connect a touchscreen
(devi-elo or devi-carol) as a USB device?

Is it as simple as starting the usb mouse device
and then telling touchscreen to look for

devu-uhci &
devu-mouse &
devi-elo smartset fd -d/dev/usbmouse0

or does a special devu-touchscreen have to
be written ?
