Normally USB device requires corresponding kernel mode
device driver (WDM). App programs need to access via
File I/O. Normally it is done by a DLL. So you need
prepare both device driver and DLL. Then the LV app
can access the DLL via Call Library functionality.

This link is one that actually pertains to USB and VISA. You would only use this procedure though if you had the USB RAW information from the vendor or you are creating your own USB device. This is often difficult to get. Typically, a vendor will provide a dll that you can use with the Call Library Function Node. What is the device?

[Deepu]

Yeah Dennis,

I got the wrong link... that was for PXI/PCI

Thanks for the correction.

It all depends on the USB device that is connected. You can look at the link I provided for USBTMC devices and devices for which you have no driver from the vendor.
