I am writing a LabVIEW program to do functional testing on a PCBA that has several USB hubs and connectors on it. I want to test each of these USB connectors for functionality. I've created an NI-VISA USB raw driver for a simple USB memory key. I can plug this device into any USB port on the board and by using the "VISA Find Resource" routine, I can tell when the device is plugged in or not. I need to identify which specific USB port the device is plugged into. I've tried using the property node for a USB raw class object. One of the properties available is the USB Interface Number, but this number never changes, no matter where I plug in the USB device. Does anybody have any suggestions on how I can do this? Thanks, Ron
