Hello,
Thank you for contacting National Instruments.
Unfortunately, you cannot use your GPIB-USB-B device under Linux. You have a couple of options here. First, you can use the driver developer's kit
DDK to make your own drivers for this platform. Second, you can contact NI sales to upgrade from USB to ENET, for GPIB-ENET can be run under Linux. If you'd like to upgrade to ENET, please call #(800)531-5066 to speak to a sales representative."
I hope this helps. Please let me know if I can further assist you.
Best Regards,
Joe Des Rosier
