Dear all, I am trying to control an instrument using USB connection and VISA. I used the VISA Driver Wizard to create the driver and the instrument is correctly recognized by NI MAX. I can also send and receive bytes. The instrument does not have any software / driver provided by the vendor so I think the only choice I have is going with the VISA wizard. The developer can send me USB low level details (command number XX, number of bytes to read, etc). Even if the instrument is correctly read by max and Vendor ID and model ID is correct, when I try to have access in labVIEW , I use the VISA open and the VISA resource name is not found.... Can you help please? Thanks.

Did you close down your other interface to it (in MAX)? You can only have one open session at a time to a resource

LabVIEW

Solved!

So I solved the problem by uninstalling all versions of LV, then installing only the 32-bit 2017 version. Took a long time, but it did the trick.
