Hi,

is it possible to open a handle to an arbitrary device
displayed/installed on the system. I know how to use
CreateFile and DeviceIoControl to access installed
hardware, but the point is: Is it possible to open a
device by only knowing its Physical Object Name,
without knowing what kind of device it really is?
Is there any way to do this from user mode with
something like CreateFile or some undocumented
NT API?

I have PDO Names like:

\Device\Ide\IdeDeviceP1T0L0-e
\Device\Scsi\ah4schpa1Port2Path0Target0Lun0
\Device\0000006b

Any way to get some handle in user mode,...

Thanks in advance...

Regards

Kerem

e.g. with NtOpenFile()
