Detect when a USB Token with digital signature is insert or remove

Can i detect when a USB Token with digital signature is insert or remove in a USB plug?

What does it show up as?

If it's just a storage drive you can check the file list on, that's easiest.

But if it's some special hardware device that doesn't show up as a drive letter you'd need to use RegisterDeviceNotification/WM_DEVICECHANGE to detect DBT_DEVICEARRIVAL notifications for the devinterface class GUID giving you the specific device type like smart cards, security devices, sensors, etc.

Thank you
it's a SmartCard and i want to detect only if it's insert or when insert/remove

If, when connected, it's in the Device Manager under the "Smart cards" category, then you'd use RegisterDeviceNotification with DBT_DEVTYP_DEVICEINTERFACE and DEVICE_NOTIFY_ALL_INTERFACE_CLASSES, then WM_DEVICECHANGE to detect DBT_DEVICEARRIVAL/DBT_DEVICEREMOVECOMPLETE and be looking for a device with the class guid {990A2BD7-E738-46C7-B26F-1CF8FB9F1391}
