    - .kdfiles with boot start drivers on Vista Anyone been able to use .kdfiles -m in WinDbg with boot start drivers on Vista? After much wailing and gnashing of teeth I am thinking it can't be done. Anyone? I have seen some posts on this but they all either go no where or the people replying didn't read very well. Here is what I have tried. I tried using bcdedit to turn on the boot debugger. Here is my output from WinDbg: Waiting to reconnect... BD: Boot Debugger Initialized Connected to Windows Boot Debugger 6000 x86 compatible target, ptr64 FALSE Kernel Debugger connection established. Symbol search path is: From the kd prompt I set >sxe ld:mydriver.sys and the debugger promptly broke after all of the boot start drivers had been loaded?? The .kdfiles mapping to my driver never kicked. I am connecting WinDbg via NULL modem cable COM1 115200 baud. I also tried loading a checked build of WinLoad.exe...still no love. I can't seem to get the debugger to hook during boot. HELP? Anyone? I have seen several veteran driver devs ask this same question with no real help. If it isn't possible, it would be nice of someone to just say so. In my case this would sure save me a butt-load of time. Thanks. Bill M.

    - File attributes not preserved on copy Hi, I am working on a filesystem driver. I have a weird problem while copying files from an NTFS volume to my volume. After the file is copied, Windows sends an IRP_MJ_SET_INFORMATION IRP with FileBasicInformation information class. Now the attributes field in the FILE_BASIC_INFORMATION structure is always zero even if the original file had read only, archive and/or hidden attribute set. So the file attributes are not preserved on copy unlike a copy between two NTFS harddisks or to a floppy disk. Is this expected behaviour? Is there anything the filesystem driver needs to do during driver startup or volume mount to ensure that Windows sets the right file attributes on file copy? Any information is greatly appreciated. Thanks, Priya Tag: trying to install a minifilter without INF file Tag: 94132

    - Problem regarding WHQL WIA Transfer Test Hi, We are currently developing a WIA 2.0 scanner mini driver. We are using Widariverex sample that comes with WDK as our reference. When we are running WHQL WIA Transfer test we are seeing one assertion to fail. "Assertion: {CC5F18FA-0436-4e78-BB83-1881841FFB8D}, Test Case: Basic Single-Item, good-parameter, cancellation-free download. " But we are able to scan and preview properly from MS default UI. While debugging I saw that "drvAcquireItemData" entry point is also returning S_OK. Can you please guide me whether I am missing any thing in the source execution path? I have copied the contesnts of the WHQL log I got after conducting the test for your reference. / *************************************************************************************************************** 4/17/2007 5:13:36.524 PM Assertion: {CC5F18FA-0436-4e78- BB83-1881841FFB8D}, Test Case: Basic Single-Item, good-parameter, cancellation-free download.

    - Enumerate Child Device Hello All, We are writing a USB-Serial driver using WDF framework. We have completed the USB part i.e handling PnP and Power Management. My problem is i want OS to enumerate a child device probably as Serial device. I want the device manager to show virtual COM port device and USB device. I did the following to achieve this. After the completion of EvtDeviceD0Entry, i have added the following code to enumerate a child device (COM) in EvtDeviceRelationsQuery NTSTATUS EvtDeviceRelationsQuery (IN WDFDEVICE Device, IN DEVICE_RELATION_TYPE RelationType ) { // Initialize UNICODE device name RtlInitUnicodeString(&uniDeviceName, L"\\Device\\SerBus0"); DeviceInit = WdfPdoInitAllocate(Device); // USB device object if (DeviceInit == NULL) { DbgPrint ("WdfControlDeviceInitAllocate failed 0x%x\n", status); status = STATUS_INSUFFICIENT_RESOURCES; } // // Set exclusive to true so that not more than one app can talk to the // control device simultaneously. // WdfDeviceInitSetExclusive(DeviceInit, TRUE); WdfDeviceInitSetDeviceType(DeviceInit, FILE_DEVICE_UNKNOWN); WdfDeviceInitSetCharacteristics(DeviceInit, FILE_DEVICE_SECURE_OPEN, FALSE); // // Assign the device name // status = WdfDeviceInitAssignName(DeviceInit, &uniDeviceName); if (!NT_SUCCESS(status)) { DbgPrint ("WdfDeviceInitAssignName failed 0x%x\n", status); return status; } // // Initialize the attributes // WDF_OBJECT_ATTRIBUTES_INIT_CONTEXT_TYPE (&attributes,DEVICE_CONTEXT); // // Create the control device // status = WdfDeviceCreate(&DeviceInit, &attributes, &serbusdevice); if (!NT_SUCCESS(status)) { DbgPrint (WdfDeviceCreate failed 0x%x\n", status); return status; } status = WdfFdoAddStaticChild(Device, serbusdevice); if (!NT_SUCCESS(status)) { DbgPrint (WdfFdoAddStaticChild failed 0x%x\n", status); return status; } } In EvtDeviceAdd i added the following code after i get the device handle. busInfo.BusTypeGuid = GUID_CLASS_COMPORT; busInfo.LegacyBusType = PNPBus; busInfo.BusNumber = 0; WdfDeviceSetBusInformationForChildren(device, &busInfo); I followed the instructions at the following link. http://msdn2.microsoft.com/en-us/library/aa490110.aspx I dint have any luck in proceeding further. Cany anyone point me if im missing anything, so that windows could enumerate a child device. I want to provide a different INF file for second enumeration. Thank You, Regards, Sushma Tag: trying to install a minifilter without INF file Tag: 94121

    - Installing Filter driver I am trying to install Filter driver using SetupAPI function as decribed in MSDN. Call SetupInstallFilesFromInfSection for the [upperfilter_inst] section. Call SetupInstallServicesFromInfSection for the [upperfilter_inst.Services] section. Call SetupInstallFromInfSection for the [upperfilter_inst] section, once for each class key it wants to register the upperfilt service for. But I see only registry is getting updated. The actual driver is not get bound to the adapters. How to do that? Tag: trying to install a minifilter without INF file Tag: 94120

    - MiniportCheckForHangEx vs MiniportCHeckForHang Hi, I am writing an NDIS6 miniport driver. In WDK it is written on MiniportCheckForHangEx do that "If a miniport driver does not complete an OID request within two successive calls to MiniportCheckForHangEx, NDIS can call the driver's MiniportResetEx function." and on MiniportCheckForHang doc that: "If a NIC driver has no MiniportCheckForHang function and NDIS judges the driver unresponsive as, for example, when NDIS holds many pending sends and requests queued to the miniport driver for a time-out interval, NDIS calls the driver's MiniportReset function" 1. If I correctly understand the doc than MiniportCheckForHangEx in contrary to MiniportCheckForHang does not care about pending sends request only pending OIDS. I tested it by pending send requests forever and indeed MiniportReset was not called. Is that the expected behaviour or did I miss something? 2. What is the meaning of "NDIS can call the driver's MiniportResetEx?" are there times that it will not call it ? Thanks Miki Tag: trying to install a minifilter without INF file Tag: 94113

    - Driver Signing Problem Hallo, For VISTA I have build a signed driver package with a "VeriSign Class 3 Code Signing 2000 CA" ID. Our Rule is using the same package for Windows XP. In Vista the installation is OK but in Windows XP I can see some errors in setupapi.log #E360 An unsigned or incorrectly signed file "c:\windows\inf\oem9.inf" for driver "XXX" will be installed (Policy=Ignore). Error 1168: What is not correct with my signing ? The result: class installer entrys (ICON, name) are not installed in registry and CoInstaller DLL is not running by the installation. When I break this signed package (insert a space into INF file) all is fine. elli Tag: trying to install a minifilter without INF file Tag: 94109

    - Can the Media Center source be aquired? We are having a large problem developing a BDA driver. The source of this problem is that the documentation for writing a BDA driver explains what everything does, but not what actually happens in terms of successfully instancing a filter that will be used by Media Center. This makes debugging impossible as very little of our code actually runs before Media Center decides not to acknowledge our device. Is the source code for Media Center available under some license offered by Microsoft? Otherwise, does anyone have a method to successfully diagnose graph building and filter caps problems?

The driver is for Server 2003 and Vista, x86 and x64. I realize this will have no effect on the install prompts etc. My question is, will the signature adversely affect the loading of the driver, assuming the checksum is OK? My concern is that the driver loader might be confused by the signature added to the .sys file. Thanks -- Tag: trying to install a minifilter without INF file Tag: 94085

    - Help writing virtual webcam driver Hi guys, I'm a newcomer the device driver development discipline. I'm short my project requires me to write a virtual webcam driver - the driver should not interact with any real hardware instead the image input is actually coming from e.g. the network.. I really looking for some pointers - that might push me in the right direction.. I've been reading a bit the last two days and this is how far I've come: 1) I would like to use KMDF - (cannot be done in UMDF correct?). 2) It seems I need to develop a "Video Capture Device" using something called AvStream (Currently I'm not really sure what AvStream does). 3) Are there any good DDK samples that might give me a idea of how to continue. I've looked a bit at the AVSHwS and it seems promising. 4) I found that a webcam driver is classified as an UVC (USB video device class) - Is this the protocol I need to implement in my driver? I really hope you can help me, in answering my initial questions.. All ideas, thoughts are more than welcome :) -- // morten Tag: trying to install a minifilter without INF file Tag: 94080

    - Problems in Vista with WiFi and Ndis (ndisuio.sys) Hello, I need help for Vista OS. I am updating a program to make connections to Wifi Networks so that it works in Vista. This program work with ndisuio.sys driver or any compatible driver based on NDISPROT sample protocol driver. For this case I stop the Wlansvc as I was doing in XP with the wzcsvc. It work without problems and Vista let me control the WiFi device. These drivers work fine in Vista and the devices I have probed work fine with them. I send these OID=B4s for make a connection: OID_802_11_INFRASTRUCTURE_MODE(0x0D010108) OID_802_11_AUTHENTICATION_MODE(0x0D010118) OID_802_11_ADD_KEY(0x0D01011D) (some times, if the mode needs it) OID_802_11_WEP_STATUS(0x0D01011B) OID_802_11_SSID(0x0D010102) OID_GEN_PORT_AUTHENTICATION_PARAMETERS(0x0001020F) They work well and they are shown by the program ndismon(PCAUSA) also when the system connects. The connection(association) with the AP is Ok and I send the neccesary security protocol (802.1X, WPA-PSK, WPA-PEAP) developed in my program and they work fine with the device and the AP. THE PROBLEM: Up to here, everything seems to work fine but the problem is with the TCP/IP and the new interface added in the system Vista. The new interface does not appear in the window "Network and Sharing Center" and the DHCP protocol does not work over it. The new interfce does not obtain IP address and it does not work although the association with the AP and the authorization and authentication with the WiFi device is Ok. I think that more actions are necessary in order to wake up the interface in the system Vista although I have not been able to find information on the matter. Any help about this issue would be very appreciated. Sorry for my bad English. Best regards, Frank Tag: trying to install a minifilter without INF file Tag: 94077

    - Vista RTM GDR release Hi, I have seen that the Vista USB driver stack is released in two different versions. The driver stack shipped with the MSDN DVD's is the RTM version: 6.0.6000.16386 (vista_rtm.061101-2205), the version that is now on the market is GDR: 6.0.6000.16400 (vista_gdr.061212-1500). I have done a binary comprision of the driver files. E.g. usbd.sys has only a new data from the compilation and a new version information. But other drivers like usbport.sys differs in more than the version. What is the difference between these versions? Is it required to test kernel mode drivers with both versions? Is RTM the latest beta version? I have got a problem report from a customer. He claims that the driver is not running with GDR that was tested successful with RTM! This problem is still under investigation. Any comments? Thanks Guenter Tag: trying to install a minifilter without INF file Tag: 94055

    - Why WindowsXP does not accept the correct NIC driver? I have a serious problem with my PC. I had to format my disk and reinstall Windows XP (with SP2), but I can not get to in web because Windows thinks that my network card is of Asound, but its of Realtek. I tried doing update driver using the Realtek RTL8139/810X Family PCI Fast Ethernet Card driver on the device manager. I tried uninstalling the driver, and then letting Windows find it again. I tried downloading new driver from the Internet (using another PC). But came out Asound. Windows simply does not let me change the driver. I logged in with Administrator account. I talked with the my ISP service provider, and they also found that the trouble is with my NIC.

The glyphs start out their position correctly but at some point we get a negative Y coordinates or the offsets for the Y coordinates restart at low numbers and all text lines are getting mixed. We noticed that it starts happening when Y > 7200 in *PrintableArea: PAIR(7200, 7200) of GPD file We need to support big table sizes 48x48 inches and have to have a good text quality for small fonts so we need to set *DPI: PAIR(1200,1200) *TextDPI: PAIR(1200, 1200) If we set DPI for lower number Windows programs like MS Word, Corel return low quality Text. Setting DPI for low resolution but TextDPI for high resolution doesn't make text better. Are there any limitation on DPI * Y ? Any help would be greatly appreciated.

    - handling parallel port interrupts Hello, I've got a question about timing incoming IR signals and decoding them in Windows. Here's my story. I've built a device which detects IR signals at 38KhZ and sends interrupts to the parallel port. Then I created (well, I didn't write it entirely, but I edited one I found on the internet) a driver to catch those interrupts and I created a usermode program to interact with the driver. So far so good, everything seemed to work fine. I receive interrupts when I press a button on my remote control or when I just connect a wire between pin 2-9 and 10 of the parallel port. But there's also a problem. For some reason, I receive way too few interrupts when I press a button on my remote control, and the time between the interrupts always is nearly identical. My only guess is that for some reason processing an interrupt hasn't finished yet when the next interrupt arrives and that therefore that interrupt doesn't get handled. That should also explain why the time between logged interrupts is nearly identical; it always takes the same time to complete one interrupt and after that it can handle another. But I don't get why handling the interrupt would take that long. My pc should be fast enough to handle it. Here's my isr and dpc routine and after that the part in DriverEntry where I connect the interrupt to my driver. When an interrupt occurs, first the isr gets called and then the dpcroutine. I hope any of you have an idea why it doesn't handle all interrupts or what the problem is and how it can be fixed. Thanks in advance, Floris van Nee BOOLEAN hwinterfaceIsr(IN PKINTERRUPT Interrupt, IN OUT PVOID Context) { PDEVICE_OBJECT DeviceObject = Context; //KdPrint( ("hwinterface.sys: Interrupt Service Routine\n") ); /* We should check if the interrupt comes from us and return */ IoRequestDpc(DeviceObject, DeviceObject->CurrentIrp, NULL); return TRUE; } VOID hwinterfaceDpcRoutine(IN PKDPC Dpc, PDEVICE_OBJECT DeviceObject, IN PIRP Irp, IN PVOID Context) { PLOCAL_DEVICE_INFO DeviceExtension; PIRP pIrp; pIrp = DeviceObject->CurrentIrp; DeviceExtension = DeviceObject->DeviceExtension; //Get the current 'time' and print it to kernel debug KeQueryTickCount((PLARGE_INTEGER)&TickCount); KdPrint(("Interrupt: %d", TickCount)); return; } DeviceExtension = DeviceObject->DeviceExtension; DeviceExtension->Level = 7; DeviceExtension->Vector = DeviceExtension->Level; MappedVector = HalGetInterruptVector(Isa, 0, DeviceExtension->Level, DeviceExtension->Vector, &Irql, &DeviceExtension->Affinity); if (MappedVector == 0) DbgPrint("hwinterface.sys: HalGetInterruptVector failed\n"); IoInitializeDpcRequest(DeviceObject,hwinterfaceDpcRoutine); KdPrint(("%d", &DeviceExtension->InterruptObject)); status = IoConnectInterrupt(&DeviceExtension->InterruptObject, // InterruptObject hwinterfaceIsr, // ServiceRoutine DeviceObject, // ServiceContext NULL, // SpinLock MappedVector, // Vector Irql, // Irql Irql, // SynchronizeIrql Latched, // InterruptMode FALSE, // ShareVector DeviceExtension->Affinity, // ProcessorEnableMask FALSE); // FloatingSave if (!NT_SUCCESS (status)) DbgPrint("hwinterface.sys: IoConnectInterrupt Failed\n"); Tag: trying to install a minifilter without INF file Tag: 94023

    - Request delegation in WDF? Hi all, I am still wondering how on earth should the, what the book "Programming the Microsoft Windows Driver Model" calls, delegate action, be handled in WDF for a bus driver? It seems very easy if you read the documentation; just take the request, call WdfDeviceGetIoTarget() on the device that wants to forward the request, send the request and that's about it. But as we learned yesterday it doesn't work. WdfRequestSend() fails every time although we verified that the target is working fine and can receive ioctls created with WdfIoTargetSendInternalIoctlSynchronously(). The same result even if we called WdfRequestFormatRequestUsingCurrentType() before the send command. So it has to do something with the Request object? We tried to create a new request with WdfRequestCreateFromIrp() by taking the original IRP with WdfRequestWdmGetIrp() but it doesn't seem to create a new IRP, instead just copying a pointer to the old one which causes a BSOD for exhausted stack. So finally we got something working by creating a new IRP and poking around with the stack location just as we would in WDM and creating a WDF Request from that IRP - but it seems very odd that we have to work on the WDM side even when we have this beautiful abstraction around it. Now we have a hybrid of WDM inside WDF and completing request correctly seems to be a nightmare - which still doesn't work... So is Request delegation possible in WDF and if so, how?

    - No way to full-proof DeviceIoControl() ??? I am in the process of developing a WDM device driver which already handles pretty well several IOCTL codes when sent by a user-mode application, using DeviceIoControl(). Now I want to make sure that driver can handle any crazy input that an application programmer may throw at it. For that purpose I placed in the switch case for the pIoStackLocation- >Parameters.DeviceIoControl.IoControlCode a default case that all it does is this: default: { pIRP->IoStatus.Information = 0; ntStatus = STATUS_INVALID_DEVICE_REQUEST; pIRP->IoStatus.Status = ntStatus; IoCompleteRequest(pIRP, IO_NO_INCREMENT); return ntStatus; } This works great (i.e. returns an error with a suitable GetLastError() code) when I test it with an unrecognized IOCTL as follows: int dummy; if ( !DeviceIoControl(hWdm, IOCTL_UNRECOGNIZED, NULL, 0, // input &dummy, sizeof(dummy), // output &BytesReturned, NULL)) but when I pass the output paramter as NULL, too (see below), the system hangs (i.e. only a hard reset would get it out of that state): if ( !DeviceIoControl(hWdm, IOCTL_UNRECOGNIZED, NULL, 0, // input NULL, 0, // output &BytesReturned, NULL)) Notice, the only difference is "NULL, 0" vs. "&dummy, sizeof(dummy)" ... On the WinDbg side, all I can see is the following: Access violation - code c0000005 (!!! second chance !!!) *** ERROR: Symbol file could not be found. Defaulted to export symbols for ks.sys - ks!KsDispatchIrp+0x3b: f82b9f0d ff10 call dword ptr [eax] Which doesn't give me enough information about what's happening in the driver. So, for now, my workaround is to never pass a NULL output buffer pointer to DeviceIoControl() - but is it really impossible to protect a driver against something like this? I thought that (not) handling an unrecognized IOCTL is a no brainer (as described above in the 'default' case). What am I missing?

    - Portable Devices device class in Vista My USB MSD device resulted in an device "generic volume" under "Storage volumes" in XP Device Manager. But in Vista that instance does not show up, instead, an instance with my product name shows up under 'Portable Devices" device class in Vista. Can anyone tell me what does this change mean to the same USB drive ? -Gary Tag: trying to install a minifilter without INF file Tag: 93992

    - DTM corrupts XP target with pnpdtest I'm seeing a problem where DTM seems to corrupt my Windows XP target when I run the PnP Driver Test. After DTM configures the target, it reboots and displays the following message: Windows could not start because the following file is missing or corrupt: system32\drivers\pnpfiltr.sys You can attempt to repair this file by starting Windows Setup using the original Setup CD-ROM. Select 'r' at the first screen to start repair. I have seen this on multiple systems. I'm using DTM from WDK 6000 with the main QFE applied.

    - ZwQueryInformationFile Returns Wrong File Size I am using ZwQueryInformationFile to obtain the size of a binary file that contains firmware. Problem is that 3 of the files return the correct size, however two files return a file size off-by-one (-1). So currently I am just doing a cheap hack. I use StandardInformation.EndOfFile.LowPart to obtain the file size in bytes. I really hope this problem is just something simple. Thanks!

    - Signing Error: No Signature was present in subject Setup displays a dialog that informs the user that the authenticity of the driver cannot be verified, and it gives the user the option to cancel the installation of the driver. The system is an Enterprise x64 Server 2003 with SP2. I expected to not see the above message since I digitally signed my driver install files. My driver is a WDM PnP function driver. Since the INF file defines the StartType as SERVICE_DEMAND_START , I only need to digitally sign the cat file. I created the *.cdf file and included the INF and SYS file. I used MakeCat to generate the *.cat file. I am using a Verisign Class 3 certificate. I use signtool to digitally sign the cat file. I use signtool verify /pa /v NAME.cat to verify the cat file was signed. I see the Class 3 Primary Certificate linking to Verisign Class 3 certificate and then to my certificate. All looks official to me. When installing the driver on the target system (Server 2003 x64) I get the warning that the driver is not digitally signed. Here are a few lines from setupapi.txt #I087 Driver node not trusted, rank changed from 0x00002001 to 0x0000a001. #I023 Actual install section: [v6_00.ntamd64]. Rank: 0x0000a001.

Error 0x800b0100: No signature was present in the subject. Do you see what is missing? Does this indicate the Authenticode certificates are not found? Or that my cat file was not signed?

    - Microsoft DVBT Network Provider Filter does not support two instances in same graph Hello All, As I have seen, looks like two instances of the "Microsoft DVBT Network Provider Filter" do not work properly. Any of you have observed the same behaviour and has found a workaround or something? The fact: I need to play two DVBT streams at the same time on a video card (dual dvbt capable). I create thus both DVBT oaths in ONE graph and run it with graphedit. I can see both rendered windows and work OK until I change the frequency in one of the DVBT providers, it won't work properly. Looks like the frequency property is internally shared with both instances and the last instance created owns the value. Am I wrong or this is a fact? THanks! Juanma, Hamburg. PS: Commment, both DVBT paths in separate graphs work OK. But I need to do it in one graph!

Hi,
Yes I know I should have an INF file, but that is another story.
I'm trying to load my minifilter driver on XP 2003 Server.

I'm using SCM to get loaded and this is working ,
my driver is getting loaded. In the DriverEntry I am failing when I call
FltRegisterFilter() I am getting error 0xC0000034.

I figure that this must be because of register settings?
Can someone tell me exactly what the settings should be for my minifilter?

TIA
