General instructions for interfacing with USB RAW devices using the NI-VISA driver are given in the article How Can I Communicate With a Device Using NI-VISA USB RAW Mode?
The VISA Driver Development Wizard is used to create the INF file so that Windows can detect your USB RAW device and use the NI-VISA driver to communicate with it.
However, HID Compliant devices are a special case. By default, Microsoft Windows installs a Microsoft signed driver for any HID Compliant device on your machine, which can not be overwritten by the VISA Driver Development Wizard generated INF file (on Windows Vista, Windows7).
The best way to access an HID Compliant device is by making calls directly to the
library provided in Windows Vista and Windows7. In LabVIEW, this can be done using the Call Library Function Node
located on the functions palette under Connectivity » Libraries and Executables » Call Library Function Node
