USB를 인식은 하는데이벤트 처리 부분 switch (nEventType) 에서 더 이상 들어가질 않네요
자료를 찾아봐도 다 똑같은데
디버깅 결과도 제각기 다릅니다.
소스를 간단하게 올려봅니다.

main.cpp
MGBOOL MainMessageProc( HDIALOG hDialog, PMG_EVENT pEvent )
{
UINT nEventType;
DWORD dwData;

switch( pEvent-message )
{
case WM_CREATE: {return OnCreate(hDialog, pEvent);}break;
case WM_TIMER: {return OnTimer(hDialog, pEvent);}break;
case WM_DESTROY: {return OnDestroy(hDialog, pEvent);}break;
case WM_DEVICECHANGE: { return OnDeviceChange(nEventType, dwData);}break;//nEventType
case (MG_USERMSG+1):
{
printf(TEST Button Clicked\n);
}
break;
default:{}
}
return true;
}

WNDPROC.cpp
MGBOOL OnDeviceChange(UINT nEventType, DWORD dwData)//UINT nEventType, DWORD dwData, HWND hwnd, WPARAM wParam, LPARAM lParam
{
printf(device 함수 진입\r\n);
printf(%d,%d\r\n,nEventType,dwData);
switch (nEventType)
{
printf(nEventType\r\n);
case DBT_DEVICEARRIVAL:
printf(DBT_DEVICEARRIVAL\r\n);
break;
case DBT_DEVICEQUERYREMOVE :
printf(DBT_DEVICEQUERYREMOVE\r\n);
break;
case DBT_DEVICEQUERYREMOVEFAILED:
printf(DBT_DEVICEQUERYREMOVEFAILED\r\n);
break;
case DBT_DEVICEREMOVEPENDING:
printf(DBT_DEVICEREMOVEPENDING\r\n);
break;
case DBT_DEVICETYPESPECIFIC:
printf(DBT_DEVICETYPESPECIFIC\r\n);
break;
case DBT_CONFIGCHANGED:
printf(DBT_CONFIGCHANGED\r\n);
break;
case DBT_DEVICEREMOVECOMPLETE:
printf(DBT_DEVICEREMOVECOMPLETE\r\n);
break;
default:
printf(error\r\n);
break;
}
return true;
}
