getlasterror( ) returns "2 " .

But , my dirver is shown in the Winobj.exe or in the DevView.exe,
and see nothing singularity.

sorry for again , I am at the end of wit .

Is the IrpTracke kit will help ? I would have a try

Show your CreateFile call. Other things to check:

  1. Have you created a symbolic link (or device interface) like the samples?
    CreateFile can’t open the \Device\Foo name directly.

  2. If you have created the device object outside of DriverEntry, make sure
    that you clear the DO_DEVICE_INITIALIZING flag.
