I want to create a siumulated USB-6341, but that model is missing from the list of X-series devices available under the simulated devices in MAX. All I see under the X-series devices available for simulation are PCIe devices. I have MAX 4.7, DAQmx 9.1.5 and LabVIEW 2010. I have done this on other computers running slightly older versions of software and seen this device on the list, so there must be some software component that I did not install, but I can't figure out what it is. Any suggestions?
