, can you tell me the, use the interface to get the agreement version? Because if you give a link in the general idea, did not say the interface interface to get field is said protocol version? Can you give some tips? Because there is no integral, cannot download the link you gave the demo

with IOCTL_GET_USB_DESCRIPTOR device descriptor, excuse me I why complains GetLastError 1, the code is as follows:

TCHAR diskPath [DISK_PATH_LEN];
Swprintf_s (diskPath, _T (" \ \ \ \. \ \ PhysicalDrive % d "), Disk).
HANDLE hDevice=CreateFile (
DiskPath,
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,//the default security attributes
OPEN_EXISTING,//disposition
0,//the file attributes
NULL
);
MyPrintLog (_T (" hDevice Disk: % s: % ld "), diskPath, hDevice);
If (hDevice==INVALID_HANDLE_VALUE)
{
Fprintf (stderr, "CreateFile Error: % ld \ n", GetLastError ());
}
DWORD dwBytes;
STORAGE_DEVICE_NUMBER number;
Int nResult=DeviceIoControl (hDevice, IOCTL_STORAGE_GET_DEVICE_NUMBER,
NULL, 0, & amp; Number, sizeof (number), & amp; DwBytes, NULL);
if (! NResult)
{
Fprintf (stderr, "DeviceIoControl Error: % ld \ n", GetLastError ());
}

Cstrings strDebug;
USBSCAN_GET_DESCRIPTOR getUsbDesc={0};
GetUsbDesc. DescriptorType=USB_DEVICE_DESCRIPTOR_TYPE;
GetUsbDesc. Index=1;
GetUsbDesc. LanguageId=0;

USB_DEVICE_DESCRIPTOR usbDevDesc={0};
DWORD dwInDataSize;
Bool bRet=DeviceIoControl (hdstDisk IOCTL_GET_USB_DESCRIPTOR,
& GetUsbDesc, sizeof (USBSCAN_GET_DESCRIPTOR), & amp; UsbDevDesc, sizeof (usbDevDesc), & amp; DwInDataSize, NULL);

if (! BRet)
{
StrDebug. The Format (_T (" bRet: % d, Error: % ld "), bRet, GetLastError ());
AfxMessageBox (strDebug);
}
StrDebug. The Format (_T (" % 4 x "), usbDevDesc. BcdUSB);
AfxMessageBox (strDebug);
