I need to make the usb3.0 port work in usb2.0 mode, to do some testing, and then revert the usb port to 3.0 mode. can someone help me about this. thanks a lot
I don't think this is a LabVIEW question. Who makes the USB port hardware? Who makes the driver that it uses? What Operating System are you running? Does the OS have some system calls that can do this for you? Have you tried to search the Web for an answer to this question?

P.S. -- if all else fails, can you find a plug-in board or USB 2.0 expansion hub (that can plug into a USB 3.0 port but runs at USB 2.0 speeds -- should be fairly inexpensive)?
