    - KMDF driver for XP Hello All, I am using Windows XP SP1. I have downloaded the WDK 6001 with KMDF version 1.7. when I tried to load the sample driver "echo" or "toaster", the following error message is generated "The specified resource name cannot be found in the image file" Release notes says that, the sample drivers provided with KMDF 1.7 can run on Windows Server 2003 / Vista. Even a simple driver with DriverEntry with only KdPrint() on KMDF with CoInstaller of 1.7, same error message is coming. Please let me know how to solve this problem. Also, whether can I use this WDK / KMDF version for XP driver development? -Kans. Tag: [KMDF] General question: test of a 64 bit driver Tag: 95305

    - How to get the packet of KS_TVTUNER_CHANGE_INFO in Analog tuner Dr Hello: I am studying analog tuner driver. I start from DDK Sample "anlgtuner". In graphedt, it can play. When i want to change the channel, it stops work with error code "Incorrect function 0x80070001". It seems that the function to receive KS_TVTUNER_CHANGE_INFO is missed in driver from DDK doc: when the tuner switches from one channel to another, A minidriver must propagate a tuning packet from its tuner filter, through the crossbar filter, and then into the analog video input pin on its capture filter. This packet is only available in user mode until it reaches the capture filter. The minidriver receives this tuning packet as a KS_TVTUNER_CHANGE_INFO structure on the analog video input pin of the minidriverâ??s capture filter. I add AVStrMiniPinProcess callback routine in KSPIN_DISPATCH of the video input pin of the capture filter. But this routine was never hit and error still occured. So how to get the packet of KS_TVTUNER_CHANGE_INFO in Analog tuner Driver? Could somebody point me out? Thanks Max Tag: [KMDF] General question: test of a 64 bit driver Tag: 95304

    - code optimization hurt my driver Once built with the default optimization in free build, my driver cannot ackledge the interrupt flags (writing back to clear). Once I added /Od and /Oi, the driver works fine again. Anyone has suggestion where should I check for such kind of problem ?

    - make USB hub easily identifiable Some quick background: We are making a set of USB medical data collection devices. Most commonly, they will be packaged together and permanently connected to a USB hub in the same case, however they will also be available as independent devices. I need to know whether a unified device is connected or a bunch of individual modules, among other things the user should be informed if one of the devices fails in the unified collection. The hub chip uses an EEPROM that specifies the VID, PID, and device number. How can I use the standard USB hub driver for our device but tag it in a way I can detect while enumerating devices (using e.g. SetupDiCreateDeviceInfoList, SetupDiGetDeviceInterfaceDetail)? It would be best if I can control the name of the device which appears in Device Manager after the driver loads, but as long as I can distinguish our hub+devices group from a device attached to a standard hub it will be fine. Should I put in a different VID/PID pair (we can get numbers assigned) and write an INF that loads the Microsoft driver? Where would I find an example of that? Or would it be better to leave the VID and PID alone and change the device number? Any advice would be appreciated. Tag: [KMDF] General question: test of a 64 bit driver Tag: 95268

    - IOCTL_USB_USER_REQUEST Hi, I wish to use IOCTL_USB_USER_REQUEST to access the raw usb device from my application. Could somebody throw some light on IOCTL_USB_USER_REQUEST.On which Windows OS it is officially supported? what are the prerequisites to use them ? My target OS range from windows 2000 to vista. Docs mention that "This request is not enabled unless the root hub is disabled." what exactly does that mean? Thanks Subodh Tag: [KMDF] General question: test of a 64 bit driver Tag: 95255

    - USB CDC driver Hi All, I am developing USB CDC driver for windows CE. I am using following functions for registry manupulations. RegisterClientSettings UnRegisterClientSettings OpenClientRegistryKey RegisterClientDriverID So using those functions I can access the registry. I need to get the string path of the handle returned by OpenClientRegistryKey function. This is because I need to pass it to ActivateDevice function. So 1. How can I get string registry path from handle of the registry ? 2. I call UnRegisterClientSettings function inside USBDeviceAttach function. But it fail is there any reason ? Please help me.

    - WdfDeviceCreateDeviceInterface Again 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.

    - Authenticode driver signing on Windows 2003 Hi, I 'm using the signtool in Win2003 R2 DDK to sign a network driver for Win2003 with authenticode using a valid VerigSign class 3 certificate. The sys file and CAT file have been embedded a vaild signature in "Trusted root Certification Authory" and "Trusted Published" store. When I install the driver, it show a "unsigned driver" warning, and appear as "Not digital signed" in Device Manager. Is there any additional requirement for the certificate or driver to use authenticode driver signing on Windows 2003? Thanks Tag: [KMDF] General question: test of a 64 bit driver Tag: 95234

    - Common buffer allocation for DMA in WDF 1.1 I have updated a WDM function driver to WDF,the DMA function(Our device act as bus master) was added into.The whole project works well but there is a problem that I have no idea about.When start my device in the device manager,if the DMA common buffer is too big for system (system can not find a big enough continus physics memory),the WdfCommonBufferCreate failed,then the OS crash with a blue screen.The followwing is my codes: WDF_DMA_ENABLER_CONFIG dmaConfig; WDF_DMA_ENABLER_CONFIG_INIT( &dmaConfig, WdfDmaProfilePacket ,//Profile was WdfDmaProfilePacket DevExt->MaximumTransferLength ); TraceEvents(TRACE_LEVEL_INFORMATION, DBG_PNP, " - The DMA Profile is WdfDmaProfilePacket ");//Profile was WdfDmaProfileScatterGather64Duplex status = WdfDmaEnablerCreate( DevExt->Device, &dmaConfig, WDF_NO_OBJECT_ATTRIBUTES, &DevExt->DmaEnabler ); if (!NT_SUCCESS (status)) { #if DBG KdPrint(("ADX: WdfDmaEnablerCreate failed with status %x\n",status)); #endif return status; } #if DBG KdPrint(("ADX: WdfDmaEnablerCreate finished with status %x\n",status)); #endif } // // Allocate common buffer for DMA // // NOTE: This common buffer will not be cached. // Perhaps in some future revision, cached option could // be used. This would have faster access, but requires // flushing before starting the DMA in PLxStartWriteDma. //First we read the buffer size from registry:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Adx16xx\Parameters\ADX,Key:DMABufferSize status = WdfDriverOpenParametersRegistryKey( WdfGetDriver(), STANDARD_RIGHTS_ALL, WDF_NO_OBJECT_ATTRIBUTES, &hKey ); status = WdfRegistryOpenKey( hKey, &keyName, KEY_READ, WDF_NO_OBJECT_ATTRIBUTES, &subkey1 ); status = WdfRegistryQueryValue( subkey1, &valueName, sizeof(ULONG), &(DevExt->dx.DMABufferSize), NULL, NULL ); WdfRegistryClose(hKey); WdfRegistryClose(subkey1); if (!NT_SUCCESS(status)) DevExt->dx.DMABufferSize=0x200000;//default buffer size is 2M #if DBG KdPrint(("ADX: evExt->WriteCommonBufferSize:%x\n",DevExt->dx.DMABufferSize)); #endif // DevExt->WriteCommonBufferSize =DevExt->dx.DMABufferSize;//sizeof(DMA_TRANSFER_ELEMENT) * DevExt->WriteTransferElements; status = WdfCommonBufferCreate( DevExt->DmaEnabler, DevExt->WriteCommonBufferSize, WDF_NO_OBJECT_ATTRIBUTES, &DevExt->WriteCommonBuffer ); if (!NT_SUCCESS(status)) { #if DBG KdPrint(("ADX: WdfCommonBufferCreate failed with status %x\n",status)); #endif return status; } I track into my codes,found that the code run to WdfCommonBufferCreate.My problem is ,if failed , the WdfCommonBufferCreate should return an error status code ,then the driver loading will failed with the status code,but not give me a blue screen. Can any one give me suggestions?Is the bug fixed in the version 1.5 KMDF? Tag: [KMDF] General question: test of a 64 bit driver Tag: 95227

    - COM port naming Hi, I am working on a WDF serial port driver wherein I create a virtual serial COM port and I need to have the COM port number of my choice always whenever I load the driver. For this I had created a device map and written that value using RtlWriteRegistryValue(). By doing this I am able to get the COM port number of my choice in the Hyper Terminal, but the device manager is showing the COM port number which windows has assigned. Now I want the COM port number of my choice to be reflected even in the Device Manager. Can anyone of you please help me in resolving issue? Thanks in advance.

    - PsSetLoadImageNotification changed ? In my driver I make a call to PsSetLoadImageNotification () and get a callback as expected. One of the params in the callback is the ProcessId. I'm saving the processId to note when a particular (say, my) user mode component is loaded so that when I see Ioctl's I can assure myself that I know who I'm talking to. In XP this worked fine, the same code in Vista does not: Once the user mode program is running , I dump out the process using !process 0 0 in windbg which indicates that the ProcessId that I got in my callback is that of the Parent CID not the guy I'm loading Of course, when I do PsGetCurrentProcessId() in my DeviceControl routine, I get the process's Id, and I never recognize my particular user mode component. Any ideas, beyond of course going back to an XP box and making sure that the behavior I think I saw is really happening there? -- Gak - Finecats Tag: [KMDF] General question: test of a 64 bit driver Tag: 95222

    - INF file processing API functions Hi, I am trying to understand why is there a need for INF file processing functions when, for example, we can use standard C/C++ File IO functions. I have a few questions. What is advantage of using INF file processing API such as SetupOpenInfFile? And what is proper method of chain of actions needed to properly read a Hardware ID of a device from INF file if you are searching through a whole directory full of INF files? Suppose, device belongs to NET class and we want to match a network adapter Hardware ID to the one present in some INF file. My guess is we can eliminate any INF file that does not belong to NET class. Need some guidance on how to properly do this. More details can be provided if need be.

    - DeviceIoControl blocks even in Overlapped I/O mode? How is this possible? Could someone please clarify the term "Overlapped I/O" (or "Pending I/ O")? I thought that if I implement and use it properly, DeviceIoControl() would never wait/block, leaving it instead to a WaitForMultipleObjects() or WaitForSingleObject() down the line. However, in a recent buggy driver implementation of mine I managed to make DeviceIoControl() block in a write operation... How is this possible? I thought that the "no wait intelligence" (in overlapped mode) is built into the DeviceIoControl() code and not dependent upon the device driver implementation. Have I misunderstood? What am I missing? Thanks, Don Tag: [KMDF] General question: test of a 64 bit driver Tag: 95217

    - How to develop UVC webcam driver on win2k Dear all, As our customer request driver of UVC webcam for the early Windows OSes, I need to develop a driver for UVC webcam on Win2K. But I have some questions just as below: 1 Can MS USBCAMD minidriver or AVStream achitecture support UVC webcam driver development? I means if the UVC request/command can be sent to Webcam successfully, or some special trick is need to get/set request thru interface. 2 Is there any special request for the webcam hardware? in other words, besides UVC HW logic, another no-UVC HW interface for custom driver? 3 What is right sample code to kick off UVC webcam driver?

I need to create some ks filter properties and events as a vendor's own USB phone driver . Is it possible we base this driver on Windows system audio driver ? I've researched that a custom audio driver can use portcls driver ( collection of port drivers) and adapter driver ( collection of miniport drivers ) . Should I use usbaudio.sys as adapter driver ? If this way ok how can I make its portcls driver ? I did not find sample code like portcls.sys from DDK . Tag: [KMDF] General question: test of a 64 bit driver Tag: 95198

    - Failed to load driver on Vista I have an application that works with two particular drivers, one is loaded on boot and second is loaded when my application is working. I use the first driver to load and unload the second driver using ZwLoad/ UnloadDriver. Everything works fine on Win2K and XP but I encounter some problems in Vista. Sometimes I get error 0xC0000034 upon ZwLoadDriver of my second driver. I looked for my drivers and devices in the system, but monitors such as DeviceTree or WinObj do not show any of them. On the other hand, from a full memory dump I can see my second driver loaded. >From some reasons that I can't explain, I see that when I run my application "as administrator" and immediately close the application everything suddenly get back to track. When I run my application as administrator I even do not attemp to load the driver. Of course, after computer restart the application starts to work fine as well. It is important to mention that both drivers are properly signed. Any help is very appreciated. Tag: [KMDF] General question: test of a 64 bit driver Tag: 95189

    - [KMDF] Hardware for the PLX9x5x sample Hello, I'm interested by the PLX9x5x sample but the link in WDK for the product kit and the hardware specification is dead. Where can I find these informations and where can I buy the "PLX9656/9653RDK-LITE board"? I found this link (http://www.plxtech.com/pdf/product_briefs/9656rdk-lite.pdf) but I'm not sure... Thank you!

    - AllocateCommonBuffer failure in Vista I'm using the the routine "AllocateCommonBuffer" to allocate memory for my PCI device. The call succeeds in WinXP but in Vista it fails. Does any one have an idea what it may be? Is DMA different in Vista? Thanks in advance. Tag: [KMDF] General question: test of a 64 bit driver Tag: 95153

    - Adding adapters to a bridge using a script... I need to add adapters to a bridge using a script. I can enable/disable the bridge using devcon, and tweak some settings using netsh, but how to remove and add an adapter to the bridge? The problem is that when we add and remove our virtual bridge to the adapter, the MAC address always goes to the same number (AA-BB-CC-DD- EE-01), unless we do a strange dance - remove the virtual adapter, disable the adapter, enable the adapter, add the adapter. Of course when we reboot, it reverts back to the AA-BB-CC-DD-EE-01 again, and then we need to do the dance. So, we just need a script that does the dance for us. Adding and removing the adapter. I looked for INetCfg interface and the BINDVIEW sample in the DDK (or NETCFG in earlier DDKs), but I don't have a DDK. Help! Tag: [KMDF] General question: test of a 64 bit driver Tag: 95146

    - Question about USB device setup class Hi! I have a question about setup classes. My device is a USB device which is used for software updating inside wireless communication devices. As I read from WDK documentation, I should not place my device under USB setup class: "This class includes USB host controllers and USB hubs, but not USB peripherals. Drivers for this class are system-supplied." However I see from WDK 6000 samples, that the "bulkusb" driver is placed under the USB category. From the WDK documentation I also find the statements like: "If your device meets both of the following criteria, you should assign it to an existing device setup class: - Your device's installation and configuration requirements match those of an existing class. - Your device's capabilities match those of an existing class." So is it correct to create a new device setup class in my case or to place my device under the USB setup class? I ask this to avoid any problems on WHQL certification... -- Lauri Ehrenpreis Tag: [KMDF] General question: test of a 64 bit driver Tag: 95143

    - Change communication mode of parallel driver Hello, i'd like to change from ECP to CENTRONICS mode on Windows XP. I tried IOCTL_IEEE1284_GET_MODE/IOCTL_IEEE1284_NEGOTIATE and the "DefaultModes" entry within RTL_REGISTRY_SERVICES-Parport\Parameters. Both without success. IOCTL_IEEE1284_GET_MODE allways return the same ( wrong ) values ( read protocol = NIBBLE, write protocol = CENTRONICS ). When using IOCTL_IEEE1284_NEGOTIATE to change the settings, the returned PARCLASS_NEGOTIATION_MASK structure is always filled with read=0 and write=0. The "DefaultModes" registry entry seems not to change anything. Any ideas on how to change the communication mode successfully? Has anybody ever tried these IOCTLs? Thank you.

    - USB over IP Virtual Host Controller Interface driver Hi, I am imprmenting the project of USB over IP without using any seperate hardware. To implement such a system , I read that I have to implement virtual host controller interface driver. I have experience in USB driver but not on host controller driver. I have developed a Vrtual Graphics Driver , in which we were redirecting all the calls to GDI engine, but I not able to understand 1) the concept behind Virtual Host Controller Interface driver. 2)its role in the kernel stack. 3)How to implement it ? I am totally confused as to from where to start or what to read. Please if you have any suggestion or reference then kindly share it with me..

    - How to Power Down USB Device Programatically? Hi, In my generic usb function driver during the IRP_MN_START_DEVICE device i need to power down and power up a usb Smart Card Reader. I have tried sending PoRequestPowerIrp to power down and up the device, it returns successfully.But the power supply to the device is still continued (It has an LED to indicate that). I looked in to IOCTL_INTERNAL_USB_CYCLE_PORT Docs say that is simulates unplug and replug so no power down takes place during this IOCTL. Do i need to complete the Start Device and wait for idle notification then power it down, power it up and configure. Is that a right way to do it? Is there any other way i can stop the power supply to the device from HUB and start it again? Any help is appreciated.. Thanks Subodh Tag: [KMDF] General question: test of a 64 bit driver Tag: 95126

Is it really impossible to install uncertified driver on a 64 bit Vista ?

If yes, how to test the driver ? ^^

Thank you!

The document Eliyas pointed to gives you the details; the 10,000 foot
summary is that you create your own signing certificate, sign the driver
with it, install the certificate in the certificate store on your debug
machine, and turn on test signing mode with /testsign.

It does work -- I've done it. ;)

Also, if the kernel debugger is attached, unsigned drivers are allowed to
load.
