I searched for WDK today on Connect and it found it. Just my two
cents.

I cannot understand why Clear Buffer is needed and what is it. I do not
remember such command in the spec, so, it is probably some proprietary command
of yours.

Once more: on bulk writes from host to device, device sees arriving
packets. After each packet, it must respond with ACK/NAK/STALL.

STALL is fatal error on pipe.
ACK means - OK, device have consumed the packet OK, the host will send the
next bytes of the pipe data as the next packet.
NAK means - sorry, device is not ready to accept more data on this pipe,
but will be ready soon when some internal conditions on the device (buffer
fullness) will change. After the device have responded with NAK, the host will
_retransmit the same packet again and again_ till STALL or ACK will be returned
by the device.

Also note that USB bulk transfers have the notion of logical frame
boundaries (unlike TCP which has none). The logical frame boundaries
established by the host can be sensed by the device, and can carry some
semantics the device can use.

The host establish a logical frame end on the end of each IRP's buffer.

The device senses this frame end when it either gets the zero-length
packet, or the packet of the incomplete length.

All of this is in host+device hardware and in device firmware, and is
hidden from the host software at all.

Got wrong sources? Perhaps this stuff is for WinCE.

Jeff, Thanks for the clarification. Will the callback be hit even if
the dll is already loaded? e.g, kernel32 is used by so many
applications so it may already be loaded when I open notepad.exe.

I'm trying to instruct the build utility to not use precompiled headers in

explicitly tell the build utility to NOT include precompiled headers. Does
anyone know how I would approach this? Thanks.

Try adding

USER_C_FLAGS = /Y-

Can't say for sure but this is the normal approach to things like this.

Hi,

I had the impression that I need to get a WHQL signature to have my driver
loaded on Server 2008 x64.

After carefully studying the latest DDK documentation along with the white
paper

http://download.microsoft.com/download/9/c/5/9c5b2167-8017-4bae-9fde-d599bac8184a/kmsigning.doc I
started to think that an SPC from Verisign with a cross-certificate is
enough, as long as the Windows Logo is not required, even for the drivers
for which there's a WHQL test.

ms-help://MS.WDK.v10.6001.071220/DevInst_d/hh/DevInst_d/driver-signing-over_838ed908-96ff-411c-a5f3-c253e7e7cb53.xml.htm

"To be considered signed by PnP device installation, the catalog file of the
driver must be signed by WHQL ***or*** signed by a third-party release
certificate (a Software Publisher Certificate (SPC) or a commercial release
certificate). A WHQL release signature ***should*** (not MUST) be used if
one can be obtained. "

"Note also that for 64-bit versions of Windows Server 2008 and Windows
Vista, the kernel-mode code signing policy further requires that a
kernel-mode driver be signed by WHQL ***or*** by an SPC"

I did a quick test and my non-boot driver doesn't get loaded on Windows 2008
x64 even when it has an embedded SPC signature and an SPC-signed .CAT file,
both with the cross certificate. 2008 x64 doesn't even recognize the INF as
valid (it works fine on 2003 x64).

Where's the truth?

Thanks

Hi,

I have a driver package that consists of multiple INFs for different classes
(e.g. SCSI Adapter and CD-ROM). The binaries for the same device are
different for x86 and x64 but have the same file name in different source
folders. The drivers are NOT class drivers but functional ones.

Can I use a single CAT for all my INFs and drivers? I have some doubts
because I can see the device identifier from the first INF file embedded
into CAT.

If I need multiple CATs, does Microsoft charge their WHQL signature fee per
driver package or per CAT file?

Thank you

We are trying to give our USB CDCACM device the ability to auto install
driver from usb mass storage device. We made a composite device with 3
interface. 2 for CDCACM and 1 for mass storage. When the device connects to
PC, the driver shall be installed from mass storage.
However, when the device connencts to PC, Windows pops out an "Add
Hardware Wizard" and it asks us to install driver for CDCACM device. The mass
storage does not show up until we install the driver for CDCACM device
manually. We cannot auto install driver for CDCACM from mass storage because
it only shows up after we install CDCACM driver.
We think the result is due to the enumeration order of composite device
interface, so we exchange the interface order of CDCACM and mass storage.
Nevertheless, it doesn't work.
Why can't windows install built-in driver for mass storage before
install CDCACM driver?
We use XP SP3 for testing, therefore we don't need any hotfix from MS.

Hi, I am new to vista APO. After I read the document, I get few
questions.

1) Is APO DLLs need to be WHQL signed(or something like that), when
release to customer?
2) If I provide my own LFX/GFX for vista 64, do I need to provide both
32-bit and 64-bit DLL? or just 64-bit DLL? (64bit WOW will do
conversation for me?)
3) from documents, it seems that there can't be multiple LFX or GFX
for one Audio engineer(like speaker/ microphone)? That is to say, if
user has installed 3rd party driver(like realtek), and it has its own
LFX/GFX, will it replace 3rd party LFX/GFX when I install my LFX/GFX?
or is there any soultion to keep them both?

Thanks,

Hi,

Created a thread in the driver and it will be running at HIGH_PRIORITY, and
I need to stop the thread by setting an event from an another dispatch Call,
which is running at PASSIVE_LEVEL.

Since the thread is running at HIGH_PRIORITY, the dispatch function is not
getting able to set the event.

Is it right to raise the IRQL in the dispatch cuntion to IRQL=DISPATCH LEVEL
before KeSEtEvent, and lower the IRQL down.

Thanks

As long as your HIGH_PRIORITY thread is not running away (means not using
all available CPU), but waits on events instead, there should be no problem
with setting an event on PASSIVE_LEVEL. Of course, HIGH_PRIORITY thread will
get CPU immediately, but then I don't understand why it creates a problem
for you.

Hello,

I have been assigned to develop an application like VNC, for desktop
sharing with multiple monitor support. Currenly we have a prototype
using the hook mechanism. Now I am assigned to redo it using the video
mirror driver.
As I am quite new to this topic, i need your help to complete the task
in the stipulated time.

So far, I was able to install the sample mirror driver in DDK. The
debug log indicates, functions like DrvCopyBits, DrvBitBlt etc were
invoked in the mirror .dll driver.

What I want to accomplish is
1- How to get the full screen data using the morror driver
2- Is there a way to get the screen update from the driver.
( in the prototype using Hook, we get the updated RECTs from hook
callback.
So we can capture data on that RECT by comparing two full screens)

As such, my intensin is to get the screen data ( full screen or
updates) and compress it and send to the remote machine over an
socket, whre the desktop is being viewed. Please let me know how i can
achieve this.

Also, suggest some book or info where I could get a clear idea of the
functionlity of this system.

I have posted this in another group also.. pls excuse me.

Thanks
Kidilan

Hello,

I have a problem with Windbg.
I have started it in debug mode and have waited for the debuggee to
connect. But I get the following outputs:

Opened \\.\com1
Waiting to reconnect...
BD: Boot Debugger Initialized
Connected to Windows Boot Debugger 6001 x86 compatible target, ptr64
FALSE
Kernel Debugger connection established.
Symbol search path is: G:\Windows Vista\Symbols;G:\Projects\Pwe_common
\common\rssw\drsw\radar\pcirsc\windows\xp\i386
Executable search path is:
*** ERROR: Module load completed but symbols could not be loaded for
winload.exe
Windows Boot Debugger Kernel Version 6001 UP Free x86 compatible
Primary image base = 0x00584000 Loaded module list = 0x00684e58
System Uptime: not available
The call to LoadLibrary(bootext) failed, Win32 error 0n2
"Das System kann die angegebene Datei nicht finden."
Please check your debugger configuration and/or network access.
Shutdown occurred...unloading all symbol tables.
Waiting to reconnect...
******************** OUTPUT END ********************

The text in quotes means in English: "The system can not find the
given file"

If having an explicit break point in a DriverEntry routine the
debuggee will hang so debugger and debuggee really do not connect to
each other. But the null modem cable works and there are outputs if
the
debuggee boots in debug mode.

I think the critical point is "The call to LoadLibrary(bootext)
failed, Win32 error 0n2" and this is the reason for the shutdown of
the debugging engine.

Any idea concerning this error?

Thanks for any help,

Alexander Boegelsack

Hi all,

I've created a USB function application and want it to
communicate with windows host . I came to know about Windows Device
simulation Framework. Now I just want to know how much this framework can
help me in this case. I've downloaded Windows Driver Toolkit for Server 2008
from MS connect.
I also want to know following thing:

1. Will this WDK for server 2008 work for XP also as my development PC has XP?

2. What if I want to test this function simulation on other PC? Do I need to
install complete WDK there first?
