I know that other users are successfully using the NI GPIB-USB-HS+ interface, though I don’t have any personal experience with it. But I do believe it is the Keysight instrument and not the USB to GPIB interface adaptor that requires the HPIBS driver. As you may know, HP became Agilent, and then Keysight. So there is a chain of software compatibility and even many model numbers are the same.
