SETUPAPI函数集是一个大大的集合，里面包括的函数巨多。其功能强大，但终因无法梳理出有效有脉络需让人望而生畏。
微软对此也只是一个简单的图示：
今天我们写一段代码，来概括上面的图示：
#include <windows.h>
#include <setupapi.h>
#include <initguid.h>
#include <stdio.h>
#include <string.h>
#include <winioctl.h>
#include <locale.h>
#include <tchar.h>
#pragma comment(lib,"Setupapi.lib ")

DEFINE_GUID(GUID_DEVINTERFACE_USB_HUB, 0xf18a0e88, 0xc30c, 0x11d0, 0x88, 0x15, 0x00, \
0xa0, 0xc9, 0x06, 0xbe, 0xd8);
/* A5DCBF10-6530-11D2-901F-00C04FB951ED */
DEFINE_GUID(GUID_DEVINTERFACE_USB_DEVICE, 0xA5DCBF10L, 0x6530, 0x11D2, 0x90, 0x1F, 0x00, \
0xC0, 0x4F, 0xB9, 0x51, 0xED);
void CUsb::TestSetup()
{
const GUID* pGuid = &(GUID_DEVINTERFACE_USB_DEVICE);
HDEVINFO dev = SetupDiGetClassDevs((GUID*)pGuid, NULL, NULL, DIGCF_PRESENT | DIGCF_INTERFACEDEVICE);
if (dev == INVALID_HANDLE_VALUE)
{
printf("No HDEVINFO available for this GUID\n");
return ;
}
SP_DEVINFO_DATA dev_info_data;
dev_info_data.cbSize = sizeof(SP_DEVINFO_DATA);
for (int i = 0; i < 255; i++)
{
if (!SetupDiEnumDeviceInfo(dev, i, &dev_info_data))
{
break;
}
TCHAR id_inst[MAX_PATH] = { 0 };
if (!SetupDiGetDeviceInstanceId(dev, &dev_info_data, id_inst, MAX_PATH, NULL))
{
break;
}
printf("%d\t %ws\n", i, id_inst);
{
TCHAR HardwareId[MAX_PATH] = { 0 };
ULONG length = 0;
SetupDiGetDeviceRegistryProperty(dev, &dev_info_data, SPDRP_HARDWAREID,NULL, (PBYTE)HardwareId, MAX_PATH, &length);
for (TCHAR* p = HardwareId; *p ;p += _tcslen(p) + 1)
{
printf("\t %ws\n", p);
}
}
for (int index = 0;; index++)
{
SP_DEVICE_INTERFACE_DATA dev_interface_data;
dev_interface_data.cbSize = sizeof(SP_DEVICE_INTERFACE_DATA);
if (!SetupDiEnumDeviceInterfaces(dev, &dev_info_data, pGuid, index, &dev_interface_data))
{
break;
}
ULONG len = 0;
if (!SetupDiGetDeviceInterfaceDetail(dev, &dev_interface_data, NULL, 0, &len, NULL))
{
if (0x7a != GetLastError())
{
break;
}
}
PSP_DEVICE_INTERFACE_DETAIL_DATA pdev_interface_detail = (PSP_DEVICE_INTERFACE_DETAIL_DATA)malloc(len);
if (pdev_interface_detail)
{
pdev_interface_detail->cbSize = sizeof(SP_DEVICE_INTERFACE_DETAIL_DATA);
SetupDiGetDeviceInterfaceDetail(dev, &dev_interface_data, pdev_interface_detail, len, &len, NULL);
printf("%d.%d\t %ws\n", i,index, pdev_interface_detail->DevicePath);
free(pdev_interface_detail);
}
}
}
SetupDiDestroyDeviceInfoList(dev);

在本人电脑上执行的结果如下：
