Let me start out by explaining what exactly I'm trying to do. I have a cRIO-9068 that I would like to use the USB port on to connect to an RF module (radio) which is capable of communicating through USB. I've already gotten it working in LabView by using the USB port on my PC running Windows 7. In Labview, I'm using the VISA commands (Configure, Read, Write, Open, Close).
When I connect the radio to the USB on the cRIO, I can see that MAX detects the device because it adds the interface (ASRL4::INSTR) with the port binding "/dev/ttyUSB0". In LabView, if I do something as simple as use the VISA command to configure the serial port I get an error code "-1073807192" as shown in the attached screenshot.
In my investigation to resolve this issue, I was able to SSH into the LinuxRT OS and verify that the USB module was being recognized when the radio is plugged in, and even went so far as to communicate through the "/dev/ttyUSB0" port to my radio successfully. It seems as though it is an issue with VISA, but I can't figure out how to fix it. I tried reinstalling VISA, with no success. It seems to me that the interface Status "Not Present" reported in MAX (see screenshot), might be a clue, but I can't figure out what to do from here.
Thanks in advance!
