The GPIB-USB-HS is considered a mature product. NI recommends customers migrate to the GPIB-USB-HS+ to take advantage of newer technologies, lower prices, and longer-term availability.

The GPIB-USB-HS+ is considered a drop-in replacement for the GPIB-USB-HS, provided that a supported version of the NI-488.2 driver is installed.
