I have been tried to test the WDK signature test.
It has been passed that test.
Do you mean that?
Or it will not function correctly in PNP about IRP_MN_XXX in modem?

Thanks for answering.


no, it must be a full fledged KMDF driver that is not running in miniport
mode

Can it just like the ndis sample in DDK to win the WHQL logo,just use
the KMDF shell in driverentry,but actually use the IRP?
I use the sample,but after the IRP_MN_STOP_DEVICE,windbg wont return to
the next program line.
It seems that it won't work correctly in my driver, how can I to debug
that using windbg?
Which command should I use to prove that?
Thanks...


Doron Holan [MS] ??:

for a modem device, not really. to get a WHQL logo, your driver *must* be
a
KMDF driver.

There are many reasons that I have to write in WDM ways and It's hard
to say.
But by the way,what is "modem.sys is probably pausing incoming i/o"?
Is modem pausing for any next IRP?
or some other reasons?

modem.sys is probably pausing incoming i/o. why not fix your driver to
handle the pnp irp properly and be done with it? like don said, there
is
no
need to learn this stuff, KMDF takes care of this for you and lets you
concetrate on implementing the guts of your driver
