wie man USB-hardware-id mit der Geräte-id?

Schließlich habe ich mein problem gelöst...danke für Eure Antworten...
Ich bin Entsendung der code hier kann es hilfreich sein für jemanden... von diesem code bekommen wir alle hardwareids der Geräte, die connceted zu unserem system..

HDEVINFO hDevInfo;
   SP_DEVINFO_DATA DeviceInfoData;

   hDevInfo = SetupDiGetClassDevs(NULL,
       0, //Enumerator
       0,
       DIGCF_PRESENT | DIGCF_ALLCLASSES );

   if (hDevInfo == INVALID_HANDLE_VALUE)
   {
       //Error handling here.
       printf("Error Details:[%s]\n","INVALID_HANDLE_VALUE");
       return 1;
   }

   //Enumerate through all devices in Set.

   DeviceInfoData.cbSize = sizeof(SP_DEVINFO_DATA);
   for (i=0;SetupDiEnumDeviceInfo(hDevInfo,i,
       &DeviceInfoData);i++)
   {
       DWORD DataT;
       LPTSTR buffer = NULL;
       LPTSTR hwbuffer=NULL;
       DWORD buffersize = 0;

       //
       //Call function with null to begin with, 
       //then use the returned buffer size (doubled)
       //to Alloc the buffer. Keep calling until
       //success or an unknown failure.
       //
       // Double the returned buffersize to correct
       // for underlying legacy CM functions that 
       // return an incorrect buffersize value on 
       // DBCS/MBCS systems.
       //
