Need to use multiple drivers (VISA and win-USB) for a single piece of hardware

I am communicating with a piece of equipment via Labview (using an unsigned VISA USB driver) and via commercial software that came with the equipment (using a signed windows USB driver) using the same computer.  The two drivers are not compatible, and switching between them is painful due to the unsigned nature of the VISA driver (also, this task needs to be undertaken by a lightly trained production operator). 

 

Does anyone know of a way to temporarily disable the VISA driver (in a way that is easy to undo)?

 

Thanks,

Dave

Hello Dave,

 

What is your method currently to disable the VISA driver? What versions of both drivers do you have?

 

You may be able to switch between which driver is primary, but it would still be a process. This article gives a description on how to do so with NI-VISA, you may be able to switch between the two.

What is the instrument?  Can it be controlled via SCPI commands?  If you are able to use the SCPI commands to control the instrument, it may not be necessary to switch back and forth.
