I think the above is missing the point; presumably David has a USB 
joystick and a USB port
on his target computer; so no need to do "the down-and-dirty" with the 
soldering iron.

What he needs to do is ascertain is, for example, whether the USB 
joystick sends Unicode chars when
it is moved, rather like the chars for right-arrow and left-arrow on a 
keyboard, and whether
they are interpreted by the computer as mouseDown and mouseStillDown 
signals.

I have a Belkin Nostromo (silly gaming pad) which I use for 
RunRev/LiveCode programming:
now it comes with a set-up control panel where one can set all the keys, 
wheels and twiddly things
on it to do what one wants - having set up one's preferences 
RunRev/LiveCode can pick up
whatever I do on the Nostromo without any trouble at all.

However, I suspect that David is trying to be somewhat cleverer than me, 
insofar as he wants
to 'skip' the requirement of an intermediate, platform specific, set-up 
panel / driver-thingy.

My own inclinations would be to run round the corner and buy a crappy 
USB joystick and plug the
thing in, and then set up some silly little stack that will pick up the 
signals from the USB stick

[ they cannot be that other-worldly ]

and see whether they can be interpreted as KeyDown, rawKeyDown type 
signals . . .
