fastrak

What advice would you give to someone who is trying to use the the fastrak dls over a USB connection? FTgui works just fine, but with the following code:

polhemus = viz.add('fastrak.dls')
polhemus.reset()
viz.tracker()

one of two things happen. Either the boring error message:
fastrak.dls Polhemus Fastrak v1.0
** ERROR: Failed to connect to Polhemus Fastrak over USB or COM1

Or the program simply exits instantly after opening a new window and giving the following output:
fastrak.dls Polhemus Fastrak v1.0
** NOTIFY: Connected to Fastrak over USB Connection
2 station(s) detected

Which to me seems like its working? This also happens on the testPolhemus script. I get the same results whether or not I include the "PORT_FASTRAK = 1" option or any variation thereof. How should I go about making this work?
