Multi USB RAW device testing at the same time using PXI controller

[NIPA]

Hello,

I can able to communicate with one USB RAW device using Labview..., The question is ... How can i communicate with multiple RAW USB device at the same time , on one PXI controller , which has same product and device ID and no serial #. How can i find which device is connected to which port at computer?

* there are few ways i can do that ...1) write serial # and serch for that when USB connected... but it is not possible in my test production environment..

2) serach for enumuration string and get the port # connected...(dont know how to serach?)

3) There is a link ( http://zone.ni.com/devzone/cda/epd/p/id/3622 ) for USB RAW connection but it says you have to close the session of one USB and start another which means i can not communicate at the same time...)

Hello NIPA,

You can add the driver for your USB device using the VISA driver Wizard. If you have several devices attached to your computer, they will appear with different address in MAX (you can also change their Alias). By having different VISA resources name, you can have several opened sessions in LabVIEW.
