How to set and test a USB keypad device in VISA Raw mode

[ee_engineer]

I can setup a simplified USB keypad device using NI-VISA Raw mode but I can't seem to read interupt data from the device. Basically, I want to be able to push a button on the USB keypad device and then read the output hex code using LabVIEW. Do I have to further configure my device through NI-VISA in order to read the device output?

This example shows how to get the interrupt from your USB device.
InterruptUSB.vi

Let me know if this helps!
