求助，DeviceIoControl返回50

[尴尬猫]

 HANDLE hDevice = CreateFile(L"\\\\?\\usbstor#disk&ven_kingston&prod_datatraveler_3.0&rev_#60a44c425091f1a1b98300ba&0#{53f56307-b6bf-11d0-94f2-00a0c91efb8b}",
        GENERIC_WRITE | GENERIC_READ, FILE_SHARE_WRITE | FILE_SHARE_READ,
        NULL, OPEN_EXISTING, 0, NULL);

    if(hDevice == INVALID_HANDLE_VALUE)
    {
        printf("Failed to open USB device\n");
        return 1;
    }

    USB_DEVICE_DESCRIPTOR *deviceDescriptor;
    DWORD bytesRead;

    BYTE descriptorBuffer[1024];
    USB_DESCRIPTOR_REQUEST request;
    request.ConnectionIndex = 0; // 连接索引
    request.SetupPacket.bRequest = USB_REQUEST_GET_DESCRIPTOR;
    request.SetupPacket.wValue = (USB_STRING_DESCRIPTOR_TYPE << 8) | 0x00; // 获取设备描述符
    request.SetupPacket.wIndex = 0x0409; // 英文语言 ID
    request.SetupPacket.wLength = sizeof(descriptorBuffer);
    BOOL success = DeviceIoControl(hDevice, IOCTL_USB_GET_DESCRIPTOR_FROM_NODE_CONNECTION, &request, sizeof(USB_DESCRIPTOR_REQUEST), &request, sizeof(USB_DESCRIPTOR_REQUEST), &bytesRead, NULL);

我这边想用C++代码获取USB设备的descriptor的信息。这边success总是为0，GetLastError()获取的值为50（貌似为不支持网络请求）。

不知道DeviceIoControl函数是否是哪里传值有问题？求大神帮忙！！！！！！！
