USB3 Vision Ports
The NI CVS-1459RT provides two standard A USB 3.0 ports to acquire images from two USB3
Vision cameras simultaneously. The USB ports also support common USB mass-storage
devices such as USB flash drives, USB-to-IDE adapters, keyboards, and mice.
LabVIEW usually maps USB mass-storage devices to the /U, /V, /W, or /X drive, starting with
the /U drive if it is available. Refer to the
LabVIEW Help
for more information.
