driver for "Fujitsu Takamisawa USB Touch Panel"?

I've got Linux running happily on a Panasonic Toughbook CF-T4 (and I
love this laptop!). The laptop has a touch panel that I can poke with
my finger in Windows. I'd really like it to work in Linux.
I've done lots of searching and haven't found a Linux driver for the
touch panel, which is reported as "Fujitsu Takamisawa USB Touch Panel".
The Ubuntu Device Manager tells me its "info.capabilities" include
"input" and "input.joystick". "lsusb -v"  tells me the
"bInterfaceProtocol" is "Mouse". Does this mean I can use an existing
joystick or mouse driver? (I've clumsily tried both without success.)
The device file for the touch panel is "/dev/input/event1", and I can
see it spit out promising batches of data whenever I touch the panel.
It makes me tempted to write a driver.
1. How can I definitively determine whether a Linux driver exists
for this device?
2. Can I use an existing mouse or joystick driver with it?
3. If the answers to the above questions are "no", then I'd like to
write a driver for it myself. Where should I start? Is there
an existing driver I should modify (fpit?) or should I start
Thanks for helping out this newbie,
