Your RegisterDeviceNotification[^] code is probably working correctly, however it will only detect changes while your application is running.

You failed to mention what type of USB device your application needs to enumerate. I will assume that you need all USB device types. You will essentially need to call SetupDiGetClassDevs[^] and pass the enumerator filter of "USB". Dont be frightened by the Windows Driver Kit references in the MSDN documentation. You will be able to use the SetupAPI without the DDK installed, although I believe you will need Platform SDK/Microsoft SDK.

The following link should be enough to get you started:
How to enumerate hardware devices by using SetupDi calls[^]

You should modify the Microsoft sample code to something like the following:

#pragma comment (lib,"Setupapi.lib")
hDevInfo = SetupDiGetClassDevs(NULL,"USB", 0,DIGCF_PRESENT | DIGCF_ALLCLASSES );


You can perform additional device filtering using the System-Supplied Device Setup Classes[^] or other Enumerator strings such as "USBSTOR".
