Intersense-900 wand and headtracker

[Daniel1]

Hello Jeff,
Thanks for your reply. I did all you ask me to do according to the link provided, and I also tried to add wand tracker to it with the code bellow, but it's gave me an error. Please I need your help again. How can I solve this error problem? ERROR: Failed to create extension sensor with intersense.dle

code:
viz.go()
viz.setMultiSample(4)
vizconnect.go('vizconnect_config.py')
dojo = viz.addChild('dojo.osgb')
PORT_INTERSENSE = 3
isense = viz.add ('intersense.dle')
tracker = isense.addTracker(port =3)
tracker1 = viz.add('intersense.dle')
#keyTracker = vizconnect.getTracker('keyboard').getNode3d()
tracker0Tracker = vizconnect.getTracker('tracker0').getNode3d()

import vizshape
axes = vizshape.addAxes()

#viz.link(keyTracker,axes)
viz.link(tracker0Tracker,axes)


The errors are:

** ERROR: Failed to connect to Intersense tracker on port 3
** ERROR: Failed to create extension sensor with intersense.dle
