Enumerate all non-plug and play drivers

Use setupapi functions. Something like this:

unsigned                 devIndex;

SP_DEVINFO_DATA devInfo;

ULONG                   ulStatus, ulProblemNumber;

CONFIGRET            crRet;



HDEVINFO devs;

devs = SetupDiGetClassDevsEx(NULL,NULL,NULL,DIGCF_ALLCLASSES,NULL,NULL,NULL);



devInfo.cbSize = sizeof(devInfo);

for(devIndex=0;SetupDiEnumDeviceInfo(devs,devIndex,&devInfo);devIndex++)

{

crRet=CM_Get_DevNode_Status(&ulStatus,&ulProblemNumber,devInfo.DevInst,0);

if ( ( crRet == CR_SUCCESS ) && (ulStatus & DN_LEGACY_DRIVER ) )

{

if ( SetupDiGetDeviceRegistryProperty(devs,&devInfo,SPDRP_DEVICEDESC,NULL,(PBYTE)Buffer,sizeof Buffer,ULL) )

_tprintf(TEXT("%sn"),Buffer );

}

}



SetupDiDestroyDeviceInfoList ( devs );
