who can give some help about avstream driver.
Hi,
I have realized the usb camera driver which based on stream class
framework,but now I want to re-realize it based on avStream framework. now I
have two questions,who can help me.
1. AvStream's advantage to stream class.
2. if I want realize the usb camera driver based on avStream,which sample I
can refer in DDK.
thank you very much. Tag: found solution Tag: 70770
problem of providing my own version of malloc/free
Due to some reason, I have to provide my own malloc/free/calloc
functions so that other parts of the driver are happy. These functions
are simply a wrapper around ExAllocatePool. However, when I compile it,
the linker complains: "warning LNK4217: locally defined symbol _free
imported in function xxxx".
This is the free() function:
void __cdecl free(void *p)
{
ExFreePool(p);
}
How can I get rid of this message? Thanks Tag: found solution Tag: 70763

Is it possible for the mirror driver does not support DrvBitBlt function?
I'm writing a mirror driver based on the DDK mirror driver sample code.
I read the documentation at the msdn library, and learned that if a
driver manages its own surface, the driver must also, at a minimum,
support DrvCopyBits, DrvTextOut, DrvStrokePath drawing functions. I
noticed that DrvBitBlt was also in the DDK mirror driver sample code.
When I hooked off the DrvBitBlt function, I got a blue screen. I'm
trying to avoid implementing DrvBitBlt because of complexity.
Could any guru tell if it is possible not to implement DrvBitBlt
function in the mirror driver?

Problem uninstalling keyboard driver
Hi,
I've written a keyboard driver for W2K/WXP which ties in with kbdclass and
works fine. It happily sits next to a standard Windows keyboard driver in
Device Manager. Problem is Device Manager gives no Uninstall option for my
driver and DevCon reports "Remove failed" if I try to remove it.
I've also written a touchscreen mouse driver which similarly connects with
mouclass and sits next to a standard Windows mouse driver in Device Manager.
This does have an uninstall option and can be removed using DevCon.
Both drivers have a similar structure, but is there anything extra I should
be doing in the keyboard driver to make it uninstallable? How should I go
about uninstalling it?
Thanks, Ade. Tag: found solution Tag: 70745
AVStream on Win98
Hi all,
Help really needed... I have managed to build a AVStream driver for an USB
device that runs on all platforms, except win98 se.
According to the documentation of AVStream in MSDN, we can run any AVStream
driver on any OS as long as the OS has DirectX ver8.0 and above.
Exclamation mark is shown in the camera icon in the Device Manager and error
code is "The NTKERN.VXD device loader(s) for this device could not load the
device driver. (Code 2)".
May I know is this problem due to AVStream? Please advise.

Strange behaviour with USB selective suspend
Hello
I've connected a usb mouse in combination with our own usb device to
the same root hub. Our device supports remote wake-up. The driver for
our usb device sends down a request for usb selective suspend. Nothing
happens. When I unplug the usb mouse, the system happely invokes the
callback routine so the driver sets device power state D2.
I find this behaviour a bit odd. Why does the usb mouse prevent our
device from going into usb selective suspend? I also replaced the usb
mouse with a different usb device but the behaviour remained the same.
This is WinXP SP2. The implementation in our driver has passed whql. Tag: found solution Tag: 70743

USB stack gives misleading indications when Polling Interval not 1
I am seeing some incorrect indications from the usb stack (XP SP2) when my
device indicates a Polling Interval of 2 on its isochronous endpoint:
My hardware has a high speed (not high bandwidth) iso In endpoint; it
generates fixed size 1000-byte packets at an interval very slightly over
250uS.
I have taken the isousb sample from the 3790 DDK, and adapted it to work
with my configuration.
Because of the data rate, it seemed sensible to increase the polling
interval on that endpoint so as to only poll every other microframe, so I
set a value of two.
I use the test app (rwiso) to read an amount of data from the device, and
the driver output is as follows:
IsoPacket[0].Length = 0x03E8 IsoPacket[0].Status = 0
IsoPacket[1].Length = 0x0000 IsoPacket[1].Status = 0
IsoPacket[2].Length = 0x03E8 IsoPacket[2].Status = 0
IsoPacket[3].Length = 0x0000 IsoPacket[3].Status = 0
IsoPacket[4].Length = 0x03E8 IsoPacket[4].Status = 0
IsoPacket[5].Length = 0x0000 IsoPacket[5].Status = 0
IsoPacket[6].Length = 0x03E8 IsoPacket[6].Status = 0
IsoPacket[7].Length = 0x0000 IsoPacket[7].Status = 0
IsoPacket[8].Length = 0x03E8 IsoPacket[8].Status = 0
IsoPacket[9].Length = 0x0000 IsoPacket[9].Status = 0
IsoPacket[10].Length = 0x03E8 IsoPacket[10].Status = 0
IsoPacket[11].Length = 0x0000 IsoPacket[11].Status = 0
IsoPacket[12].Length = 0x03E8 IsoPacket[12].Status = 0
IsoPacket[13].Length = 0x0000 IsoPacket[13].Status = 0
IsoPacket[14].Length = 0x03E8 IsoPacket[14].Status = 0
IsoPacket[15].Length = 0x0000 IsoPacket[15].Status = 0
IsoPacket[16].Length = 0x03E8 IsoPacket[16].Status = 0
IsoPacket[17].Length = 0x0000 IsoPacket[17].Status = 0
IsoPacket[18].Length = 0x03E8 IsoPacket[18].Status = 0
IsoPacket[19].Length = 0x0000 IsoPacket[19].Status = 0
IsoPacket[20].Length = 0x03E8 IsoPacket[20].Status = 0
IsoPacket[21].Length = 0x0000 IsoPacket[21].Status = 0
IsoPacket[22].Length = 0x03E8 IsoPacket[22].Status = 0
IsoPacket[23].Length = 0x0000 IsoPacket[23].Status = 0
So this suggests that every other packet is coming back zero-length.
However, when I look at the entire buffer from the user-space app there are
no gaps - every piece of data *is* there (and correct) from beginning to
end - all 24 packets. The return value from the read() call is 12*1000 yet
the whole buffer has in fact been written.
I've also used SnoopyPro to examine what the stack thinks the packets
contain, and diagrammatically (and very much simplified), this is what I'm
seeing (with "." indicating a zero-length packet):
According to stack Actually in buffer
0 1 2 3 0 1 2 3
. 4 5 6 7
8 9 A B 8 9 A B
. C D E F
0 1 2 3 0 1 2 3
etc
This is a problem to me because I will occasionally get genuine zero-length
packets (due to the data generation being asynchronous to the usb frames),
and I need to be able to detect them.
The USBD_SHORT_TRANSFER_OK flag is not set.
This only happens when the Polling Interval is 2; when it is set to 1 then
the behaviour is as expected (albeit interspersed with genuine zero-length
packets, generated by the h/w when it is polled but has no data available)
I'm running a free build XP SP2, but with checked versions of ntoskrnl, hal,
usbport.sys, usbccgp.sys and usbd.sys (also from an SP2 version).
Is it a bug in the usb stack?
There is a report of this kind of problem -
http://support.microsoft.com/?kbid=837371 - but although it is dated only a
few days ago, it seems to be saying that the issue is fixed in SP2; and I
have newer versions of all the files indicated (though why don't I have
usbccgp.sys - isn't that needed for composite devices??)
[I'm having trouble with my Win2K installation at the moment, so I've not
had a chance to compare].
In fact, as I repeat the test today to check my results (before hitting
"Send"), I'm *also* now seeing an additional effect: a packet with a length
of 1000, but contents all zero - but, again, without any loss of data -
where there *is* data in the buffer it is continous and valid (the data
stream contains a count to help spot discontinuities).
What with the results I was seeing yesterday plus this additional weirdness
I'm now seeing, I'm wondering if there are still issues with non-one values
of polling interval?
Anyone got any thoughts? Can anyone at MS confirm whether 837371 really is
fixed?
Thanks. Tag: found solution Tag: 70727

prd->u.Interrupt.Affinity = -1;
Irp->IoStatus.Information = (ULONG_PTR)resourceList;
KdPrint((DRIVERNAME " (PDO) - HandleQueryRequirements:

Converting Win2k monolithic printer driver to a Longhorn driver - Installation problems
Converting Win2k monolithic printer driver to Longhorn driver - INSTALLATION
Problems..
The current monolithic(not using Microsoft Universal Printer Driver Model)
Windows printer driver has been converted to "user-mode" and installs/runs
fine on Win2k, WinXP, and WinServer2003. However, for "Longhorn Beta1" the
following error message is given during an attempt to install the driver:
Error Message:
"The driver that you are trying to install is not compatible with Windows
Server 2003 family. Please contact the manufacturer for an updated
version."
It appears (according to the following windows log files: setupapi.app.log,
setupapi.dev.log) that the installation (via the Add Printer Wizard)
successfully copies the driver files to a system location, but immediately
after that point, the error occurs and the installation is cancelled.
I suspect that when the "loader" attempts to load a driver DLL (toward end
of installation), it cannot resolve a reference in the DLL to some Win API
function (NOT IN Longhorn), and therefore the DLL is not loaded. Normally,
one would get some kind of error message that indicates a particular
function could not be found/resolved; but this may not be the case while
using the "Add Printer Wizard". I placed calls to "MessageBox(-)" at
several "entry-point" functions in the DLLs (like DllMain, DLLInitialize,
WinMain, DrvQueryDriverInfo, etc.) but these are NOT reached during
installation on "Longhorn"; however, they are reached during installation on
the other OS's.
Any Ideas?

USB Problem when using a Philips ISP1521 based hub
We are using a TI TUSB3410 USB to Serial chip and recently identified an
issue when using this device with a Philips based ISP1521 based Hub. On the
USB-IF Developers Discussion Forum a post was made that matches our problem
exactly. This post also has a statement that Philips apparently made which
states the issue is that the Windows USB host controller driver. Basically
Philips states that the host controller driver is not terminating Start Split
transactions with a Complete Split transaction. For the original posting see
http://www.usb.org/phpbb/viewtopic.php?t=6636&highlight=tusb3410&sid=92ad332153ccee7ed3babd646910e98d.
We have been told by TI that Microsoft acknowledges that this is a bug and
that it will be fixed in Vista. However in the meantime our customers are
experiencing problems when using our hardware with ISP1521 based hubs. My
question is, how can we work around this issue? Is there something we can do
in our application or in the driver to cause the host controller driver to
terminate the split transaction?
Thanks in advance for any help in resolving this issue.

Several problems building the DDK USB-Drivers Examples under W2k BE
Hello folks,
I beg you to forgive my very little skills in developing drivers. So
I'll report my problems right from the start and how I tried to solve
'em.
I'm about to develop a USB-driver that implements Bulk-, Interrupt-,
Isochronous Transfers. Getting things started, I intended to build the
isochronous USB-Drivers from the latest DDKs (3790 & 3790.1830) and
communicate with the self-developed device. I'm working on a x86, W2K
plattform and because of upward-compatibility on a x86 XP.
On both platforms I got the warning, that the existing sample would not
be valid for the current OS target. I changed the makefile in looking
after a platform >= 0x500, i.e. Win 2k. But problems went on.
While the Windows Server 2003 BE builded the driver reliably, the Win2k
BE brings up an error C1083: Cannot open include file 'usbbusif.h'.
BUILD: Compile errors: not linking c:\usb\sys directory. I looked after
the .h file and it appears in %WINDDK%\3790\inc\ddk\wdm\wnet and
...\wxp but not in the adequate w2k-dir.
I copied the missing file(s) in ...\w2k but in the aftermath over 700,
mostly syntactic errors occured while compiling. The syntax is correct.
This sounds clear to me 'cos WNET-Build works fine.
I restored the original dirs of the inc\ddk\wdm... I followed some tips
in the newsgroup. Although I have no spaces in between dir- or
file-names the error still occurs. I have no errors in compiling the
test-programs to the usb-drivers of the ddk.
I've consulted the DDK-docs, the newsgroups and Walter Oney's
'Programming the WDM 2nd ed.', but none could take me on the fast lane.
Now YOU are my only help and I appreciate that very much.

Does IPMI driver support BT interface
Hello,
Our BMC provides both BT & KCS interfaces to the host. I have following
questions in regards to Windows IPMI driver:
1. Does it support BT interface? I only see reference to KCS interface
support in the documentation.
2. If it does support BT interface, can an application specify an interface
(whether KCS or BT) for sending a command to BMC?
3. Can IPMI driver accept simultaneous commands from multiple callers and
internally serialize these commands & responses?Does driver allow an
application to register to receive IPMI commands from BMC and get event
notification once such a command arrives from BMC? (Opposite of normal
behavior, apps/Host send the IPMI commands to BMC). Linux OpenIPMI driver
allows doing so.
I will sincerely appreciate any help on these questions. Best regards,

messages. But in windbg, I can see that the printf statements getting
executed.
Is there anything obvious I am missing ? Appreciate your help. Am I linking
to some wrong libs or missing some device mapping or something ?
thanks

Debugging off the shelf device?
How can I debug an NDIS Protocol Driver on an off the shelf Pocket PC
running wince 4.2??? can I use Kernel Debugger to actually achieve this in a
same way that windbg is used? do I need TUX at the same time with Kernel
Debugger? where can I read about it? Most of documentation are about
debugging a custom image not an actual third-party device remotely connected
to PC!!!

DCOM from PortMonitor?
Hi
When I try to use a DCOM-object in my port monitor, I always get
"E_ACCESSDENIED" ... so, since I'm using a different username to do this
call, it can't be, that the access is really denied... it has to do with the
fact, that it's a port monitor that's trying to access this component... can
someone explain me, why this happens??

MmGetSystemAddressForMdl(Irp->MdlAddress)
Hi,
I'm having a problem with a 1394 driver and getting access to the needed
memory.
It is the call "MmGetSystemAddressForMdl(Irp->MdlAddress)" that fails.
It seems that there is a limitation around 65-67mb.
The following setup fails :
total packages = 16578
bandwith = 4096
buffers = 15
I guess that the system either won't allow me to allocate that amount of
memory, or there isn't enough memory left.
Any ideas about what could be wrong ??
Thank you in advance.

Suspend / Hibernate for PCMCIA device
Hi all,
I am writing driver for 16-bit PC-Card (PCMCIA) device for Windows XP, and
currently facing an issue with Hibernate and suspend.
When the machine gets Suspend/Hibernate state, the PCMCIA bus turns off our
deviceâ??s power. If I set an error code for IRP_MN_QUERY_POWER, then the OS
does not get into both states. (Pop up the dialog which informs our driver
rejects the mode).
I would like to get the OS to Suspend/Hibernate state and start using
hardware when the machine wakes up.
Does anyone know the way to keep PCMCIA deviceâ??s power during both modes?
Our device is Multi-function PCMCIA device, so the base address should be
re-written to the hardware once it turned on,
PS:
The returned value of QUERY_CAPABILIES from PCMCIA driver says that
PowerStateSpleeping1-3, and PowerStateHibernate are mapped to PowerDeviceD3.
Thanks in advance. Tag: found solution Tag: 70636
NDIS IM and hidden proxy
Hello, All!
I my NDIS IM driver I am trying to redirect all TCP traffic to localhost.
To do so, I am changing packet payload (TCP and IP headers).
Of cause, I update checksum of IP and TCP packets.
Seems like packets do not go throgh.
Is there anything else I forgot to do?
Do I need to use different miniport handle when sending packets? Currently I
am using the same one packed arrived to. How can I get localhost miniport
handle?...
I tried to redirect packets to both 127.0.0.1 and IP address of my NIC... No
luck.
Any thoughts would be appreciated.

Creating an installer for a mirror driver
Hi,
I'm fairly new to driver development, so apologies if this is rather basic,
or has been asked and answered many times before.
I have a mirror driver that I want to create an installer for. I tried using
DPInst, but it didn't add the driver to the Device Manager's list, so I
would still have to use the "Add Hardware" wizard.
Is it possible to create an installer for a mirror driver that will
eliminate the need to use the "Add Hardware" wizard, and if so, could
someone please point me in the right direction for how to do it? Everything
I've found so far relates to drivers for new hardware, so doesn't seem like
it will work for a mirror driver.
Many thanks,

Re: Page Replacement Policy on windows XP? - invalidate TLB on MP
thanks for your answer.
the article had the answer I wantted..
However there is questionable sentence.
the writer said, when the PTE is changed on muti-processor, the TLB on every
CPU is invalidated.
Is the TLB invalidated by Windows using instruction such as invlpg, or by
CPUs automatically? anyone knows ..

Can't set device interface registry data under W2K...
Hi,
I have a driver which uses IoOpenDeviceInterfaceRegistryKey() to open a
device interface registry key and then uses ZwSetKeyValue() to write values
to that key.
The driver was originally written for and runs fine under XP. But under W2K,
calls to ZwSetKeyValue() fail with 0xC0000008 (STATUS_INVALID_HANDLE) even
though the IoOpenDeviceInterfaceRegistryKey() that preceeds it returns
STATUS_SUCCESS.
Any ideas?

custom keyboard driver
I'm porting a software package from Win98 to WinXP embedded.
The software runs only on special (custombuild) PC-Hardware.
My problem is now that I have a special keyboard (connected to a custom
parallel)where I have to read the scan and return lines cyclic and generate
the keyboard input for windows.
With Win98 I did this by programming the RTC to generate interrupts ~every
4ms on IRQ 8, virtualized in VPICD and unmasked it in the VPICD.
In WinXP I didn't find a why to install my own ISR for IRQ 8! Is it possible
to do so??
Or do I have to build a cyclic timer (KeSetTimer and so on).
Does anyone knows a good code sample for polling every 5ms some hardware
ports?

Movie Maker and SRB_GET_DATA_INTERSECTION
Hi,
I am developing stream class mini driver for windows XP. We want the
driver to work with Movie maker. We tested our driver with Ulead and
DVapp and it works with both of the applications. But with Movie Maker,
I see lots of SRB_GET_DATA_INTERSECTION requests from Stream class
driver before the DVcapture stream is opened. Once the stream is
opened, we again start seeeing SRB_GET_DATA_INTERSECTION requests, and
this is where Movie maker gives "Unknown error ocurred" after some
time.
I have been trying to figure out what could be the problem for the
multiple SRB_GET_DATA_INTERSECTION request but till now I had no luck.
Is any one aware of any particular format that Movie maker is expecting
from the driver to support. If DVApp and Movie Maker both use MSDV,
then what is that Movie is expecting from the driver which DVapp does
not.
I am using Movie Maker 2.1 with Sony Camcorder. I have even tried
Movie maker with both NTSC and PAL camcorders, but no luck. I still
see the same behaviour.

DrvConvertDevMode - CDM_DRIVER_DEFAULT
Hi
I don't have a problem, but I'd like to understand this. If the
'DrvConvertDevMode' of my printer driver get's the CDM_DRIVER_DEFAULT value,
it should return the driver's default values... now, let's assume that I've
a printer driver that can handle 2 types of printers. One is a A4 and the
other one a A2 printer (that's the most significant difference). When the
driver is called, the printer name passed to it, is not a printer name, but
something like this "manufacturer drivername". So, my driver has no chance
to find out, if windows want's the informations about the A4 or the A2
printer. So, it can't insert the correct data about papersize, resolution
etc. ... could this be a problem? Does Windows ever use the data received by
this call? I don't think so... I think, that Windows never uses the
CDM_DRIVER_DEFAULT values... am I right? Or do I have to solve this problem?
What, if the printer is attached to the network and I can't return correct
values, if I can't communicate with it? (so, then it's impossible to say
something about standard values, if I don't have the printers name)...
thanks

METHOD_IN/OUT_DIRECT - Mdl
Hi all,
I'm writing a driver for a PCI device that moves huge amount of data.
Since i'm using METHOD_IN/OUT_DIRECT and Mdl to "share" Application
allocated buffers with driver and so avoiding memory-copy, i'm looking for a
similar way in the opposite direction : "share" a collection of driver
allocated buffers with my application. Is it possible to "map" or something
similar those kernel buffers as one "linear" virtual address for the
application (many kernel buffers seen as one)?
My goal is to avoid memory-copies.
Thanks in advance

DDK Build Environments
Hi Folks, it's me again.
Well, I have a checked build of my driver for 2003/x86. So now I want to
build a version for the other OS's/platforms. Building 2003/ia64 and
2003/amd64 was a snap thanks to the build environment.
But when I try to build for XP or 2000, I get the message , "The sample...
... is not valid for the current OS target." I tracked it down to the
makefile in the source directory from the sample CDROM I started with. It
just dumps this message and quits. Why is this? It just quits if
_NT_TARGET_VERSION is less than 0x502 (2003 Server).
Will the x86 version of 2003 server driver work under XP or 2000? If so,
why a separate build environment. If not, how do I get my driver (derived
from storage/class/CDROM ) to build under the older environments?
Any help or direction is appreciated. Tag: found solution Tag: 70567

Wi-Fi AP selection by BSSID
My NDIS IM driver is offering Wi-Fi services to a user-mode application,
through IOCTL calls (the driver generates NdisRequest calls to its bound
adapter). Currently, a typical association proceeds as follows (and it works
quite well):
OID_802_11_INFRASTRUCTURE_MODE
OID_802_11_AUTHENTICATION_MODE
OID_802_11_ADD_WEP (if needed)
OID_802_11_WEP_STATUS
OID_802_11_BSSID
OID_802_11_SSID
I have, however, run across an issue when faced with multiple access points
using the same SSID. I was under the impression (after reading the DDK docs
over and over) that an OID_802_11_SSID request would establish the
association AND that it would use the currently set BSSID value to further
restrict its AP selection. On both adapters I tested with (a lousy DLink
DWL-122 USB gizmo and a reliable Cisco Aironet 350 PCMCIA card) the behavior
seemed erratic - the DLink seemed to ignore my BSSID setting and just picked
the AP with the higher RSSI, and the Cisco apparently did something similar
(I couldn't do more extensive tests with it yet).
Am I doing something wrong or just plain missing a step?
Sample association that doesn't always behind to the desired BSSID:
- OID_802_11_INFRASTRUCTURE_MODE:
Ndis802_11Infrastructure
- OID_802_11_AUTHENTICATION_MODE
Ndis802_11AuthModeOpen
- OID_802_11_WEP_STATUS
Ndis802_11WEPDisabled
- OID_802_11_BSSID
01:02:03:04:05:06 (desired AP's BSSID)
- OID_802_11_SSID

Q) PCI Expansion ROM for a CardBus.
Subject : Question about PCI Expansion ROM for a CardBus.
Dear all,
I¡¯m developing NDIS CardBus device driver at Win2K/Xp. It will use PCI
Expansion ROM for CardBus CIS only.
Q1) What kinds of resource type will I get after using
NdisMQueryAdapterResources?
I found that CmResourceTypeInterrupt, CmResourceTypeMemory, and etc were
defined in ndis.h. But, there is no type for an expansion ROM. Will it be
treated as a memory(CmResourceTypeMemory) type?
Q2) Are there any side effects to BIOS or bus/bridge drivers that were from
Win2K/Xp because of PCI Expansion ROM? My expansion ROM¡¯s content is
completely empty except the CardBus CIS information.
Thank you for your attention to my question.

DeviceIoControl returns no data (WinCE 4.2)
All..
we are trying to run a dll almost exaclty same as sample NDISUIO protocol
driver on an actual Win CE 4.2 OS based device.
we have created a GUI that talks to this driver... here is the issue,
Our GUI can send DeviceIOControl call to NDISUIO.dll and receive the binding
information.
But when we create an exact framework of NDISUIO.dll and call it
MYDriver.dll then when GUI sends DeviceIOControl then it actually returns
"No Data Available". (I belive the return code is 259)
we have checked all the registry key, index and everything with all the
correct name... GUI returns OK after OPen and Create... so it seems that it
is able to load the MYDriver.dll correctly but not the rest...
Any idea what could be the problem or what we are missing here??
we also tried by disabling the running NDISUIO.dll on the wince and have
only MYDriver.dll but yet the same issue...
