Welcome to Ubuntu forums!
To figure out the bluetooth we'll have to look at a few things.
The thread for the Wacom Graphire bluetooth is here: http://ubuntuforums.org/showthread.php?t=674738 along with the associated community wiki: https://help.ubuntu.com/community/Wa...phireBluetooth The thread is where you would normally post bluetooth questions.
What output are you looking at that says it is a mouse?
Let's look at the output of the following (with your bluetooth on):
dmesg | grep [Ww]acom
lsmod | grep [Ww]acom
and see what you have.
Hope this helps.
