get a handle to PNP device

NTDEV
1

Hi all

Is there any way to get handle in user mode for PNP device by just
mentioning path as “\device” ? I understand that PNP devices cannot use
IoCreateSymbolicName method from DDK . Or atleast by the symbolic name that
is displayed in winobj.exe utility .
I tried to use the symbolic name that is displayed in winobj.exe utility .
It did not help me . can somebody help me ?

Thanks in advance

try \.{GUID_PnP_Manager_Created} for example:

hDevice=CreateFile(TEXT(“\\.\{D75Dfc28-4268-4bab-baa7-08af7533bdb0}”),
GENERIC_WRITE | GENERIC_READ,
0,
NULL,
OPEN_EXISTING,
FILE_FLAG_OVERLAPPED,
0
);
