problem talking to usb device in Vizard


I have written a .dll to allow Vizard to get data from a usb device that collects physiological data (ex: heart rate) from the user. The module works when I run it from Python.exe (Python 2.3, if this matters). However, when I use the same commands in Vizard, it is always unable to find the device--the other functions which do not depend on the device still work.

Unfortunately, I do not really know how the code finds the USB device because it is a proprietary function.

Is Vizard doing something that alters the ports? And how can I get around this? I am currently not including any Vizard files, if that could be the problem.

Thanks for your help,
