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 two .inf files, one for Windows XP/Server 2003 R2, the other for Windows 7/Vista/Server 2008 R2. Using the wizard for a USB device is not necessary for use on Linux or Mac OS X. At this time, the list of supported operating systems includes Windows 7/Vista/XP/Server 2008 R2/Server 2003 R2, LabVIEW RT, Linux, and Mac OS X. The .inf file created by the wizard can then be distributed with an instrument driver distribution kit.
