Hello All,

I have posted a query regarding failure of
WdfDeviceCreateDeviceInterface() in my driver with error code
0xC0000010. As suggested i have logged the message using !wdflogdump
but im not able to trace the reason for the failure from the log.

Can anyone look at the log and let me know if im missing anything. As
i told earlier the same driver works fine for Windows XP but fails for
Vista.

Here is the framework log. Please look at the line number 49 below
where the failure occured

Thank You.

Regards,
Tim

The documentation insists that WdfDeviceCreateDeviceInterface should be
called in EvtDriverDeviceAdd, not in EvtDevicePrepareHardware. Have you
tried making this simple change to your code? A brief tour of WDF
samples also indicates that the interface is typically called in
EvtDriverDeviceAdd.

Thanks for the reply.

Yes, i have tried WdfDeviceCreateDeviceInterface() call in
EvtDriverDeviceAdd() as well, but still the call fails with same
error.

This is the function call. My device is USB-Serial device.

status = WdfDeviceCreateDeviceInterface(
Device,
(LPGUID)
&GUID_DEVINTERFACE_COMPORT,
NULL );

Thank You.

Well that code looks fine. The serial sample kmdf driver appears to be
doing the same thing as well (more or less.) Obviously something else is
wrong. I am tempted to suggest falling back to WDM's
IoRegisterDeviceInterface to at least validate that conceptually this
works for your driver, but that sort of defeats the whole point of going
to KMDF to begin with.

Folks,

As we have said many times that when you see a framework function return an
error, you should first look at the KMDF log in the debugger to make sure
whether this failure is due to top-level parameter validation/state
validation done by the framework or whether this error is returned by the
underlying WDM functions that framework calls, which sometimes difficult to
diagnose.

Framework does lot of validation at the DDI level before going deep into the
implementation. If it finds any error, it logs a very descriptive message
before returning. So 99.9% of the time (trust me, I'm speaking from
experience in writing ton of KMDF drivers), you will identify your problem
right away.

The error reported by this function is STATUS_INVALID_DEVICE_REQUEST
(0xC000010).

Here is one check that stands when I look at the source code. Framework
checks the device type to see whether the caller is registering an interface
on legacy control-device. If so it returns this error with the following
message.

"WDFDEVICE %p is not a PNP device, device interface creation not
allowed %!STATUS!"

-Eliyas

I am guessing something about the device interface keys in the registry is
hosed and that the WDM call to IoRegisterDeviceInterface will also fail b/c
that is where the underlying problem is (not KMDF)

Thanks for all your replies.

I have even tried with IoRegisterDeviceInterface(), but this call also
fails. Does the above log i posted help any way to know the reason for
failure.

If not how do I find the create the KMDF log in knowing the details.

Tim

Hi All,

Im exhausted in finding the reason for failure of the call.

How can i find that device interface keys have been corrupted.

Also, as Yakub said that registering an interface on legacy control-
device will fail the call. My driver is USB-Serial. My driver is
composite and has two interfaces one for USB and the other for Serial.
Im using the same driver for both interfaces. Will this make any
difference?

As i said earlier the same driver when i built for XP works fine
without any errors.

One last thing i would like know is can i ignore the call
WdfDeviceCreateDeviceInterface(). Since the device is serial, i could
use the symbolic link from the application to open/close the device.

Please suggest.

Thank You.

Regards,
Tim

No. How will applications know your USB device has arrived on the
system? What if there is a COM port conflict and the device interface
is the only way in?

Eliyas has already asked for KMDF logs of the failure. Why don't you
provide what is being requested instead of ignoring him?

I have already provided the !wdflogdump in the thread above. Do i need
to generate any other logs?

Also, the USB ends register interface is working fine. So there should
be no problem for the application to get the handle.
And for the COM inerface i could use the symbolic link to get the
handle like \\\\.\\COMx.

So, do i really need to register the serial interface?

Regards,
Tim

Im really exhausted to find out where the exact problem is.

Does the serial interface comes under legacy device?

Please suggest.

again, did you ever try to manually delete registry keys related to the
device from a previous install?

I tried to delete them but i was not able to do it. I got "Access
Denied" message.

Also, as i have told you earlier that i even tried on a fresh machine.
Still i got the same error.

Doran, I have one question for you. As Yakub said that the possbility
for failure is if im registering a legacy control device.
My device is USB-Serial.

The stack looks like

USB Root Hub-->USB Function Driver-->Serial BUS PDO-->Serial Driver.

Here are the steps i followed:

1) Plug in USB-Serial device.
2) OS recognizes as USB device, then installed the driver.
3) After USB initialization is done, i created Bus PDO using
WdfPdoInitAllocate() for USB device with device name as "\\Device\
\SerBus0" (using toaster bus -static sample).
4) OS recognizes a new device. Then i install the same driver with
serial interface.

My question is there any possilibity that the serial driver is not
attached to Serial Bus PDO. How can i verify that the stack is intact?

Thank You.

Regards,
Tim

you should not give your PDO an explicit name, there is no need for it. are
you adding the device itnerface to the serial bus PDO or the serial driver?
To see what you are attached to, do this

!wdfkd.wdfdevice <your WDFDEVICE>
!devstack <self PDEVICE_OBJECT from !wdfdevice output>

!devstack will give you the device stack and the PDO you are attached to as
well as the device instance path. send that output.

Doran,

Im giving the serial bus pdo the device name as "\\Device\\SerBus0".
The first avaiable name is assigned to it.
Im adding the device interface to serial bus pdo. Here are the logs
for both Vista and XP. There is a minor change in XP as compared to
Vista.

I guess the stack is correct. Please let me know if you find any
errors.

Thank You.
