USB enumeration project based on "C# UsbViewer" SourceForge project by Nick Vetter
That project is licensed under the Lesser Gnu Public License, version 2.1

This project is available free from any additional restrictions whatsoever.

No user interface in this project, enhancements were added to access
usb hub and port number, and the USB and HID DevicePath parameter
suitable for use with CreateFile() to access your USB device.

Beware:Calling RefreshTree() to enumerate the USB will close any open
USB devices. This behavior is the same as the Microsoft C++ UsbViewer
program.

RefreshTree() will enumerate the USB and call the Action<> routine if
the specified VID and list of PID's are found. The Action<> routine
will be called for the specific USB DevicePath passed in.

This is intended to work with the WM_DEVICECHANGE message, which gives
the DevicePath of any USB device plugged in. You have to cast the
WM_DEVICECHANGE args to certain structs to get at the DevicePath.
