因为我们只对可通过驱动器号访问的设备感兴趣，所以程序首先枚举系统中与GetLogicalDriveStrings函数相关的所有逻辑驱动器。对于每个驱动器，我们都可以使用IOCTL_STORAGE_QUERY_PROPERTY来获取VendorId，ProductId和ProductRevision等信息。 IOCTL_STORAGE_GET_DEVICE_NUMBER的使用允许我们获取驱动器类型（如CD / DVD或磁盘/软盘）。此外，两个数字：DeviceType和DeviceNumber在系统中是唯一的，我们可以使用这些数字作为驱动器的设备实例（使用SetupDi - 函数）的基础。
由于软盘和磁盘设备具有相同的定义类型FILE_DEVICE_DISK，我演示了另一个带NtQueryVolumeInformationFile参数的函数FileFsDeviceInformation，以便为设备命名特性。特性是从其他磁盘转发软盘的最佳方法，并为设备枚举选择相应的类和接口GUID（GUID_DEVINTERFACE_FLOPPY或GUID_DEVINTERFACE_DISK）。我们获取了SetupDi API枚举的所有设备的DeviceType和DeviceNumber。在我们找出哪个设备有哪个驱动器号的方式。
更重要的是设备的层次结构：父/子关系。为了演示这一点，我在代码示例中使用了CM_Get_Parent和CM_Get_Device_ID函数。因此，我们可以看到哪个USB设备具有哪个存储设备作为孩子。
我显示了有关找到的设备的一些信息。您可以将示例中的API与IOCTL_MOUNTMGR_QUERY_POINTS（请参阅Using IOCTL_MOUNTMGR_QUERY_POINTS）或FindFirstVolumeW，FindNextVolumeW和GetVolumePathNamesForVolumeNameW（请参阅http://msdn.microsoft.com/en-us/library/cc542456(VS.85).aspx）合并以获得更多详细信息如果需要。
更新：顺便提一下IOCTL_STORAGE_QUERY_PROPERTY返回的缓冲区还有其他字段，例如STORAGE_BUS_TYPE BusType（BusTypeUsb，BusTypeFibre，{{1}您也可以使用BusTypeSd来询问其他信息，例如IOCTL_STORAGE_QUERY_PROPERTY或StorageDeviceUniqueIdProperty等。如果您想获得更多USB特定信息，我建议您{{3} }，其中显示了StorageDeviceUniqueIdProperty，IOCTL_USB_GET_NODE_CONNECTION_INFORMATION_EX和IOCTL_USB_GET_NODE_INFORMATION的使用情况。
更新2：由于stackoverflow.com中邮件大小的限制，我将程序的扩展版本放在http://www.emmet-gray.com/Articles/USB_SerialNumbers.htm下。测试输出类似于http://www.ok-soft-gmbh.com/ForStackOverflow/EnumMassStorage.c
更新3：我发现了一个错误并更新了代码。请使用最新版本的代码并验证问题是否已解决。
