How to catch an event when USB device is plug-ed / unplug-ed?

[AndrazS]

I want to register for an event that is generated when user unplugs / plugs USB device into PC. I saw solutions in other languages like Delphi and C++ but cannot find a way in Labview...

I don't want to check for devices in a loop, I want to have event generated automatically when this happens.

I suspect you will need to use a .NET event that calls a callback VI and have that VI send a user event to your events case.

I would start with this Stackoverflow thread:

https://stackoverflow.com/questions/26975946/detecting-usb-device-insertion-and-removal-in-c-sharp

And try to implement roughly what that person did in, but in LabVIEW using .NET nodes.  

This is likely the .NET class to use:

Any other hint or maybe even VI that does this?

You'd have to fiddle a bit with the 'e' object to get useful info, but it's a start...

What about continuously checking visa find resource results for changes?

Thank you, but could you please save this two VIs in 2019 version? Thanks very much

Converted to 2019 LV Version and attached.
