To my recollection, National Instruments has never manufactured a product called the USB-GPIB. We have had the GPIB-USB, GPIB-USB-A, GPIB-USB-B, and now the GPIB-USB-HS. Are you sure this is a National Instruments product? Do you have the assembly number or partnumber from the device? It will be in the format of "183001C-02".
Thanks,
