Can VISA Read be used to read USB Interrupt Data?

Hardware: Instrument Connectivity Other>>USB

Problem:
I am reading data in USB Raw mode using interrupts. Can I use VISA read on the block diagram to get the data from the interrupt pipe?

Solution:
Yes, it is possible to use VISA read to get data from a USB Interrupt pipe.  Follow these steps:
  1. Using a USB Raw property node, set Interrupt-In Pipe to -1.
  2. Also on that property node, set Bulk-In Pipe to the value of the interrupt pipe you want to read.
  3. Use VISA read to read the interrupt.
