NI-VISA

USB Summary

NI-VISA provides a convenient means of accessing low-level RAW functionality of USB devices as well as support for the USB Test & Measurement Class (USBTMC) protocol. The alternative to using NI-VISA for USB device communication is writing a kernel driver or using an existing kernel driver supplied by the vendor. By using NI-VISA, you avoid having to learn how to write kernel drivers, avoid having to learn a different kernel model for each operating system, and gain platform independence and portability by scaling to other operating systems in the future.
