windows通过GUID枚举系统中所有USB设备并且显示该设备的所有属性信息

微信群里有同学问怎么获取USB设备的位置信息，这个学名叫做SPDRP_LOCATION_PATHS，刚好自己以前写过这个代码，就分享了一下。
代码如下：

#include<windows.h>
#include <winioctl.h>
#include <setupapi.h>
#include <initguid.h>
#include <stdio.h>
#include<hidsdi.h>
#include<tchar.h>
#pragma comment(lib,"Setupapi.lib ")
#pragma comment(lib,"hid.lib ")

BOOL USBEnumDevice(OUT PTCHAR pDeviceName, IN LPGUID pGuid, IN int instance)
{
    HDEVINFO info = SetupDiGetClassDevs((GUID*)pGuid, NULL, NULL, DIGCF_PRESENT | DIGCF_INTERFACEDEVICE);
    if (info == INVALID_HANDLE_VALUE)
    {
        printf("No HDEVINFO available for this GUID\n");
        return FALSE;
    }
    // Get interface data for the requested instance
    SP_INTERFACE_DEVICE_DATA ifdata;
    ifdata.cbSize = sizeof(ifdata);
    if (!SetupDiEnumDeviceInterfaces(info, NULL, (GUID*)pGuid, instance, &ifdata))
    {
        _tprintf(TEXT("No SP_INTERFACE_DEVICE_DATA available for this GUID instance\n"));
        SetupDiDestroyDeviceInfoList(info);
        return FALSE;
    }
    // Get size of symbolic link name
    DWORD ReqLen;
    SetupDiGetDeviceInterfaceDetail(info, &ifdata, NULL, 0, &ReqLen, NULL);
    PSP_INTERFACE_DEVICE_DETAIL_DATA ifDetail = (PSP_INTERFACE_DEVICE_DETAIL_DATA)(new TCHAR[ReqLen]);
    if (ifDetail == NULL)
    {
        SetupDiDestroyDeviceInfoList(info);
        return FALSE;
    }
    // Get symbolic link name
    ifDetail->cbSize = sizeof(SP_INTERFACE_DEVICE_DETAIL_DATA);
    if (!SetupDiGetDeviceInterfaceDetail(info, &ifdata, ifDetail, ReqLen, NULL, NULL))
    {
        SetupDiDestroyDeviceInfoList(info);
        delete[] ifDetail;
        return FALSE;
    }
    //printf("Symbolic link is %s\n", ifDetail->DevicePath);
    memcpy(pDeviceName, ifDetail->DevicePath, _tcslen(ifDetail->DevicePath) * sizeof(TCHAR));
    pDeviceName[_tcslen(ifDetail->DevicePath)] = TEXT('\0');
    delete[] ifDetail;
    SetupDiDestroyDeviceInfoList(info);
    return TRUE;
}

#define TO_SEARCH_DEVICE_UUID L"{A5DCBF10-6530-11D2-901F-00C04FB951ED}"

int main()
{
    //GUID hidGuid;
    //::HidD_GetHidGuid((LPGUID)&hidGuid);

    GUID AGuid;
    CLSIDFromString(TO_SEARCH_DEVICE_UUID, &AGuid);

    HDEVINFO hDevInfo = SetupDiGetClassDevs(&AGuid, NULL, NULL, DIGCF_ALLCLASSES | DIGCF_PRESENT);
    if (hDevInfo == INVALID_HANDLE_VALUE)
    {
        return 0;
    }

    SP_DEVINFO_DATA DeviceInfoData;
    for (int iIndex = 0;; iIndex++)
    {
        DeviceInfoData.cbSize = sizeof(SP_DEVINFO_DATA);
        if (!SetupDiEnumDeviceInfo(hDevInfo, iIndex, &DeviceInfoData))
        {
            break;
        }

        char szHardWareID[512] = { 0 };
        if (!SetupDiGetDeviceRegistryPropertyA(hDevInfo, &DeviceInfoData, SPDRP_HARDWAREID,
            NULL, (PBYTE)szHardWareID, sizeof(szHardWareID), NULL))

          {\
              printf(#X ":%s\r\n", szHardWareID);\
          }\
        }

            SHOW_PRO(SPDRP_DEVICEDESC);

    printf("pk");

}

这样系统中就打印出了所有关于USB设备的信息。关于GUID的信息可见：http://www.pnpon.com/article/detail-146.html

如这里我显示一个UVC摄像头的信息：

当然，这里会出现一些乱码，是因为我把所有信息都当字符串输出了，对某些项有兴趣的同学可以自行根据类型来进行格式化输出。
