To make your PXI/PCI or USB device visible to NI-VISA applications, the operating system (OS) must know to associate your hardware with the NI-VISA driver. This association is accomplished on Microsoft Windows operating systems using a Setup Information file (.inf file).
The NI-VISA Driver Wizard generates one .inf file for your PXI/PCI device for use on all supported operating systems. For a USB device, the wizard generates one .inf file on Windows. Using the wizard for a USB device is not necessary on Linux. The .inf file created by the wizard can then be distributed with an instrument driver distribution kit.
The list of supported operating systems can be found here.
