I am in the process of interfacing a 3D joystick to our 340VGX.  It has a
RS232 interface.  So far, I have been able to read its X, Y, Z and button
reports with no problem ( except the initial setup - 8bit no parity, ARGH).
Right now, I'm in the midst of getting a gl driver working so we can use
it like any other available gl device.  The driver is based on the tabletd.c
driver which used to be found in ~4Dgifts/examples/... in previous releases.
It seems to work OK, reading the reports and calling gl_changedevice() to
tell gl about the changed device state.  However, the application I've 
modified to work with the joystick (~4Dgifts/.../paint.c) doesn't read the
events reliably.   Its a back-burner project which I haven't touched in
3 weeks, and won't again for another 1 or 2, but if you have any questions 
regarding what I have accomplished, ask away.  If I get it working, I'll let
you know.
