我用的还是vc 6.0
查msdn得到的
HRESULT GetDeviceInfo(
LPDIDEVICEINSTANCE pdidi
);
参数和返回值都和你说得不一样呀
你确定 GetDeviceInfo 是如你所说的吗？

GetDriveType
The GetDriveType function determines whether a disk drive is a removable, fixed, CD-ROM, RAM disk, or network drive.
UINT GetDriveType(
LPCTSTR lpRootPathName // root directory
);
Parameters
lpRootPathName
[in] Pointer to a null-terminated string that specifies the root directory of the disk to return information about. A trailing backslash is required. If lpRootPathName is NULL, the function uses the root of the current directory.

The return value specifies the type of drive. It can be one of the following values.
Value Meaning
DRIVE_UNKNOWN The drive type cannot be determined.

好像没办法识别出来。
在windows中，USB和硬盘一样对待。
