Lemme first give a recommendation: buy a POWERMATE! They are terrific, 
fantastic, best thing since .... well, best thing EVER!

The PowerMate works great with O under Linux if you use an application
called "evrouter". In fact, you can route events from the PowerMate
(actually: any event) to any application with an X window. Now, evrouter
will also work with the spacemouse, so there is your hint.

Ditlev Brodersen and Jesper Karlsen in our lab came up with a great way
of interacting with O using the PowerMate. First, the scroll-wheel on
the mouse is connected to the Dial Function (the little arrow in the
lower left-hand corner that shows what pseudo-dial is active). Next, the
PowerMate controls whatever function the arrow points to. Simple, and
very, very useful.

Here is the .evrouterrc file you need in your root to implement this
functionality. You may need to change the device names. Use "evrouter
--dump /dev/input/event*" to figure out what device the PowerMate
uses... it depends on what USB port it is plugged into.


----- 8< ---- snip ----
Window "O_Linux"
"Griffin PowerMate" "/dev/input/event3" any rel/7/1 "XKey/Right"
"Griffin PowerMate" "/dev/input/event3" any rel/7/-1 "XKey/Left"
"Logitech USB Receiver" "/dev/input/event2" none rel/8/-1 "XKey/Down"
"Logitech USB Receiver" "/dev/input/event2" none rel/8/1 "XKey/Up"
"Logitech USB Receiver" "/dev/input/event2" none key/276 "XKey/y+e+s+KP_Enter"
"Logitech USB Receiver" "/dev/input/event2" none key/275 "XKey/n+o+KP_Enter"
-----8< ----- snip ----

(The last two lines map a couple of extra buttons on the mouse to "Yes" 
and "No", respectively). Ahhh, it so great! :-)

Enjoy,
Morten

PS: there is similar application called "PowerMated", but it can only
handle PowerMate events. However, if that is all you need, it is more
advanced than evrouter.
