IS-900 Wand Data

[Kaminski]

Hi All,
I am unable to retrieve button data from my IS-900 Simtracker wand. When using the following commands:

isense = viz.add('intersense.dle')
wandTracker = isense.addTracker(port=4,station=2)
def printData():
    print wandTracker.getData()
vizact.onkeydown('p',printData)

I only get two datapoints in the list, such as '[127.0,37.0]' -- just the joystick data. Is there any way to make sure that I have the most recent version of intersense.dle? I suspect I may need to update the intersense firmware, as it is probably pretty old, but want to exhaust any other options first.
