I need help getting started on USB control of an instrument in C# or VB.net. I linked to the ivi.visa.interop library, but am at a loss how to properly initialize and talk to an object via the USB interface. Any help or point me to an article would be appreciated.

Hello Brain,

What instrument are you talking about? Spectrum Analyzer?

The communication setup in VB .NET or C# would be the same as for any other GPIB or LAN instrument. You would just need the correct VISA address string for the USB device. This address can be found in the Agilent Connection Expert and would have the format of "USB0::2391::1031::MY43000786::0::INSTR". This is one time that I recommend using a VISA Alias. You can find more information regarding communicating with USB instruments in AN1465-12 Using USB in the Test and Measurement Environment.
