CreateFile() with GUID on 98ME

NTDEV
1

Hi all,

I installed my WDM class driver on Windows 2000. It’s for 1394 target
device, and on the top of sbp2port.sys. Application can open the
driver by using CreateFile(“\\.\…{xxxx…}”, ).

But on 98ME, even if my driver is installed successfully, CreateFile
(“\\.\…{xxxx…}”, ) returns INVALID_HANDLE_VALUE and
GetLastError()=0.
What is different between 98ME and W2K about CreateFile() with GUID ?

Thanks,
