hi - i'm using VS2010 and .net 4 running on Windows 7. I want my app to respond to a specific usb device being connected to the computer - while the app is running. is there an event that i can trap? can you provide some code that would show how the call back would work?
the usb device is of my making, so i have some control over the device protocol. however it uses the ftdi chip to control the enumeration, so i don't have control over the device driver. it instantiates as a USB serial device. The actual device is an Arduino Nano.
thanks,

thanks, but this shows up as a serial device (COM port). i suppose i could scan for a new COM port using the serial.ports but i would rather try and get a notification.

There's a device change notification via the Win32_DeviceChangeEvent WMI provider. However, this provider doesn't really tell if a new device is connected via USB right away.  You can enumerate USB devices via Win32_USBControllerDevice and see what's changed.

It may be easier to just pinvoke RegisterDeviceNotification and pass GUID_DEVINTERFACE_USB_DEVICE as the filter's class type.
