You can issue the IOCTL_STORAGE_GET_MEDIA_TYPES_EX to differentiate. Here is an example code:

//////////////////////////////////////////

DWORD dwOutBytes;
HANDLE hDevice = CreateFile(_T("\\\\.\\A:"), GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL);

if (hDevice != INVALID_HANDLE_VALUE)
{
DEVICE_MEDIA_INFO dmi;
DeviceIoControl(hDevice,
IOCTL_STORAGE_GET_MEDIA_TYPES_EX,
NULL, 0,
&dmi, sizeof(dmi),
dwOutBytes,
NULL);

if ((MEDIA\_TYPE)dmi.RemovableDiskInfo.MediaType == RemovableMedia)
{
    //USB disk
}
else
{
    //Floppy
}

}

CloseHandle(hDevice);
