    - How to get debug prints in WinDbg from Vista I'm trying to debug my property page provider application on 32bit variant of Vista Ultimate by using WinDbg with a serial connection to try and capture the snapshots being sent by the "OutputDebugString" calls, but nothing comes out to the command window! The same application works just fine under Windows XP, Server 2003, and Windows 2000. I've inserted the "IsDebuggerPresent" and "DebugBreak" function calls only to learn that the former returns a FALSE to the local variable receiving the value when the breakpoint is hit on the latter call. What isn't clear is why the debug connection is established and control is passed to the debugger, yet "IsDebuggerPresent" returns a false and "OutputDebugString" calls are not routed through the connection? I've tried setting the "Debug Print File" as defined in http://www.osronline.com/article.cfm?article=295, but to no avail. Is there another trick to getting debug print statements out of Vista to WinDbg that I'm missing? Tag: storport requests queue Tag: 95434

    - Property sheets in Printer Preferences I have a problem with a property page in the printer preferences. I am setting a handle to my current printer in the creation of the property page. Page.lParam = (long)((OEMUIPSPARAM*)(pPSUIInfo->lParamInit))->hPrinter; When I open this page I save this printer handle in case WM_INITDIALOG: // OpenPrinter hPrinter = (HANDLE)((PROPSHEETPAGE *)lParam)->lParam; VERBOSE(PRNTEXT("Printer handle [%x]\n"), hPrinter); UserData.hPrinter = hPrinter; PUserData1 = &UserData; SetLastError(0); if ((PUserData = (CBMYUSERDATA*)SetWindowLong(hDlg,GWL_USERDATA,(DWORD)PUserData1)) == 0) { dwError = GetLastError(); } Now when I get into the case case WM_NOTIFY: it works to retrieve this printer handle and work with it, but when I press a button on the dialog it goes into case WM_COMMAND: and my handle is false! What am I doing wrong here? I need the access to the printer handle to use GetPrinterData and SetPrinterData. Any help appreciated. Thanks, -- \Manfred Tag: storport requests queue Tag: 95430

    - kernel memory hog There is a certain well know virus/spyware protection company, (not mcaffe, not symantec) that uses a gigantic chunk (around 78 MB ) of paged memory in the kernel and NEVER relinquishes it. If this stuff is installed on a computer, my software , which uses a substantial chunk of paged memory from time to time will simply not function. So far I've not gotten anyone's attention beyond the 1st line of technical support The unnamed company is much bigger than me, what can be done????? I'd hate to think about forcing my driver to load early, grabbing what it needs before this hog gets it snout in the trough ....That would result in 2 hogs with the expected results ... blah blah. -- Gak - Finecats Tag: storport requests queue Tag: 95427

    - strange things about NET_BUFFER_LIST hi everybody I write a miniport driver under Vista base on the sample rtlnwifi, and I crypt the out data. What I do like this: 1, get the NET_BUFFER from NET_BUFFER_LIST 2, get the MDL from this NET_BUFFER 3, get the data address of the MDL 4, so I copy all the data of the NET_BUFFER_LIST to a buffer use this method, and I crypt the data within the buffer(size of data not changed) 5, at last I copy the data back to NET_BUUFER_LIST, send it out through the NIC on the other PC which has Vista on it, I decrypt the data. The problem is: I share a fold, and copy some files in it, such as 123.txt or aaa.bmp, from PC1 to PC2, PC2 can get the file correctly, but the strange thing is that the files on PC1 are changed, even the fold is read only! aaa.bmp can not be recognized as BMP file, and the content of 123.txt which should be "123" also can not be recognized. It seems that when I crypt the data and copy it back to NBL, I also change the content of the file(or the content in memory, because after I reboot, the files are be OK). But I think that the NBL which my miniport get from the protocol driver should can be modified, it should not changed the content of any file or other things. Sorry for my poor English. -- Arthur Tu best regards Tag: storport requests queue Tag: 95417

    - Does devcon.exe work at all? I am trying to use devcon.exe to ease the pain of repetitively re- installing a device driver under development for test & debug purposes. The device driver I am developing is based on MSVA (i.e. has no real hardware). When I attemp invoking it like this: devcon.exe update msvad.inf I get the error message: "devcon.exe: Invalid use of update." It seems that it also requires hwid as the second parameter? So I typed: devcon.exe hwids * but all I get is: "No matching devices found." What could be not matching in the wild card * ????????? What does devcon.exe do? Does it work at all? Or am I so sleepless and tired that I can't even get a clue how to use a simple tool like this? Thanks, Don P.S. If there is another way to re-install a driver (specified by .inf and a path to the actual location of the .sys driver file) without the annoying required mouse clicking on the update driver wizard, I would appreciate describing it here.

    - Spooler does not inform the Port Monitor about errors I have compiled the XPSDrv demo targeting Windows Vista and run it on Windows XP. It fails printing some documents causing the applicaitons to hang when some standard print ports are used. I'm writing a custom print monitor grounding on the DDK example. Both the redmon and my monitor receive a premature EndDoc -- after a single 22-byte write is made. The following error is recorded in the System Event Log: " The document Microsoft Word - XPSDrv_Config-1.doc owned by valentin failed to print on printer XPSDrv Sample Driver. Data type: RAW. Size of the spool file in bytes: 405633. Number of bytes printed: 65577. Total number of pages in the document: 11. Number of pages printed: 0. Client machine: \\MERCURY. Win32 error code returned by the print processor: 2147549183 (0x8000ffff). " The same problem is observed when using RedMon -- it starts your application and delivers only 22 first bytes to it. There is no way to inform the application about failure since the monitor is not aware of it itself. I was trying getting error flag from job status retreived via GetJob in the EndDoc of my monitor -- The status is PRINTING for normally finished jobs and is additionally SPOOLING for the troublesome jobs. But but no error observed. Furthermore, I have also noticed that XPSDrv does not notify the printqueue. I have a monitor application, which logs all the activity in a printer's queue but it is silent on the XPS sample driver regardless of whether the job is printed sucessfully or fails. But that is another story. I'm sure that 1) XPSDrv must be repaired; and 2) threads must fail fast. The latter means that you should stop a task once one of it steps (which likely is a preconditioin for the subsequent stages) fails. I see no reason to invoke further processing from the monitor when printing fails and the output is incomplete, therefore. Thanks Tag: storport requests queue Tag: 95414

    - Device Setup Class Question Dear All, We're developing a scientific instrument which communicates via USB to transfer experimental procedures from the PC and stored results to the PC. Can anyone advise on what Device Setup Class this should go into? I can't see one but creating a custom setup class seems a like a big step for this one product (all the others are major groups of devices) We are using the Jungo system to do the comms, so we don't have a separate driver as such, just an inf file to tell Windows to use the Jungo driver when our instrument is connected. The instrument uses interrupt-mode transfers only. Thanks for your help. Tag: storport requests queue Tag: 95412

    - Is there a MS approved general purpose USB driver ? Hello MS team and group members, I'm searching for a general purpose USB driver approved (aka signed ) by MS that is available in Vista and/or XP and allows simple raw transfers to/from device endpoints, mainly bulk and control transfers but iso will be a nice addition. Is there such a beast included with ddk/sdk or I have to do it the hard way ? Best regards, Mircea CIocan Tag: storport requests queue Tag: 95410

    - composite device behavior of UVC device on Win98/ME/2000/XP? I found UVC device would be a multi-interface USB device. For example, interface 0 is for video control interface and interface 1 is for video stream interface. As I konw, multi-interface device will display composite device first, and then find driver for each interface. However, it seems that XP SP2 only query driver for interface 0 of UVC device after display composite device. It doesn't query driver for interface 1 of UVC device. If I plug in UVC device on WinME, it will query driver for interface 0 and 1 of UVC device after display composite device. If I plug in UVC device onWin2000, it doesn't display composite device. Why doesn't Win2000 find composite device first for UVC device? I think the behavior difference is a serious problem for developing UVC driver on these OS. For example, do I need to write different driver for each interface of UVC device on WinME? Do I need to handle multi-interface in one driver on Win2000?

    - What's the best way to develop UVC driver for Win98/ME/2000? Our device follows UVC spec. Microsoft provides standard driver usbvideo.sys for UVC device on Win XP SP2 or later I would develop the UVC driver for older OS such as Win98/ME/2000. USB Camera driver can be developed based on AVStream or USBCamd model. As I know, usbvideo.sys is a AVStream driver. AVStream driver needs new DirectX is insatalled. I am not sure whether this would be a issue for users of legacy OS. We already have developed the camera driver based on USBCAMD model for other PCam devices. I hope we can develop UVC driver based on our current driver. But I don't know whether any driver architecture limitation exists on USBCAMD model. Could anyone give me a suggestion?

    - Debugging for beginners I have just started to learn Video Capture device development. I have built and installed the testcap sample that comes with the DDK. It have tested it using AMCap and I can see the pretty test pattern (thanks Microsoft). My next step is to understand how the driver works. To do this, I would like to step-by-step the driver through a debugger. However, I am unsure how to attach the debugger to the driver - I knew when I was working with a WIA device I had to debug the WIA service. Does WDM work similarly? Or should I be attaching to AMCap? Is it possible to debug the driver on the same machine as it is running on - or do I need two computers connected by a cable? Any guidance on the simplest approach would be much appreciated.

    - Software Publishing Certificate Certificate Authority You document KMCS_Walkthrough.doc says to purchase a â??Software Publisher Certificate from a commercial CA.â?? And â??For a list of SPC CAs, see â??Resourcesâ?? at the end of this paper.â?? There is no list of CAs in the Resources at the end of the paper. Later on your document says to go to http://www.microsoft.com/whdc/winlogo/drvsign/crosscert.mspx â??This Web page includes: â?¢ A list of Root Authority cross-certificates. â?¢ A list of CAs that provide SPCs for kernel-mode code signing.â?? But again there is no list of CAs, but I will assume that the companies in the Cross-Certificate List are included in the CA list. I then picked VeriSign to investigate purchasing a â??Software Publisher Certificateâ??. But I cannot find this certificate available from this source. Why is this so hard? Please, tell me specifically what â??certificateâ?? or whatever to purchase in order to sign kernel mode drivers. On one of the examples in the document it says, â??Issued by: VeriSign Class 3 Code Signingâ??. So I went to VeriSign but the only information I could find says that this is for object signing for Internet Explorer, etc. Why is this so hard? Does VeriSign sell what I need or do I have to look elsewhere? Where should I look and what should I buy? The only mention of Digital Signing and Microsoft talks about Microsoft Authenticode to sign .exe, .cab, .dll, and .ocx. But, I want to sign a kernel mode driver. Is this the certificate or is there some other certificate? Why is this so hard? Also is there an updated document and web page that has correct information? Tag: storport requests queue Tag: 95388

    - How to share a common file in 2 different inf set? Hi, Based on the INF copyfiles directive describe in the link below, it seems that for files that is shared between 2 different inf driver sets, there is no way to ensure that the latest version of the file gets retain in the system since the COPYFLG_OVERWRITE_OLDER_ONLY flag is ignored by digitally signed sets. http://msdn2.microsoft.com/en-us/library/ms794560.aspx Does anyone knows of any way to safely share a common file between 2 different inf driver set, such that one can always ensure that the newest version of the file always gets retained by the system, no matter what the order of installation was? Or is it not possible to share a common file between 2 inf driver set that is digitally signed? Thanks KS Tag: storport requests queue Tag: 95382

    - accessing physical memory mapped to a pci board I would like to view physical memory that is mapped to a pci board. (I am writing a driver for the board for a real-time OS and I would like to see what data is in the board's registers after a successful startup in Windows to help recreate that in the other OS.) I tried using a tool called WinIO to try to create a virtual address to that physical memory. It works for both read and write of some addresses, like 0x9FFF0. However, the resource the board uses is address at 0xE8100000 which I cannot pick up with the tool. I have confirmed that address in windows device manager and in the BAR0 entry in the table that the PCI board registers with windows. Is there some protection in Windows that I must circumvent to view that memory? I am running XP SP2. The board's driver is installed and the board is functioning properly in windows while I am trying to read the memory. I have 1 GB of physical RAM and a swap file of 1.5 GB. (the memory address that PCI board is at appears to be about 3.8 GB offset (0xE8100000)... I'm not sure why it is able to have an address that is beyond the sum of the physical and swap memory.) I appreciate any thoughts you have. Thanks, John Tag: storport requests queue Tag: 95364

    - [WIA] Minidriver (UMDF/WDM), usbscan (32/64 bit) and certification Hello, In order to use a scanner on Windows XP/2003/Vista, we can't use an UMDF driver, can we? So, we have to start from the scanner minidriver sample "wiascanr", which is a WDM driver. Is it ok for Vista? In the WIA architecture, we have to make a minidriver (user mode) but we need an USB driver (kernel mode) for instance... Is "usbscan.sys" always correct? And for a x64-based version of Vista? Finally, in order to have a "Microsoft certification", are "wiascanr" and "usbscan" usable? Thank you very much!! Tag: storport requests queue Tag: 95362

    - Job opportunities Hi everyone, My employer has opened or is about to open several positions. Four of them require skills and proficiency in Windows driver writing, especially in Network and Storage drivers. Thus there are great chances that the potential candidates are readers of this newsgroup (and a few other ones. I am cross-posting). I know this group is not made for that purpose and I apologize in advance to those of you who are not interested (sorry for the cross postings too, but the skills we are searching are quite hard to find, I want to maximize our chances to find the right future colleagues). Two positions are opened in Paris, France and two will be opened in the USA (east coast) very soon. In each location there is one Senior Engineer position and one Developer-Engineer position. Contact me in private (jobs at windowsdiskless dot com) for more details (this is a forwarded e-mail address and I will receive the e-mails sent to this address).

On x86 Free Build Environment, MSC_OPTIMIZATION defaults to /0xs. I understand that /Oxs implies the use of the Frame Pointer Omission (/Oy) option. but /Oy- is appointed in compile. This cause is so that it is written as the following in "i386mk.inc" . DBGFLAGS=$(DBGFLAGS) /Oy- CFLAGS=$(386_FLAGS) $(NT386FLAGS) $(STDFLAGS) $(DBGFLAGS) $(PERFFLAGS) $(USER_C_FLAGS) Why will /Oy- be set ? Will there be any important meaning in setting /Oy- ?

    - WDF DMA use Hi. I'm designing a device driver that interacts with a master PCI DSP. I have read the documentation regarding the DMA abstraction and have some questions. The way that the DMA will work is packet-based mode, and packets will be 4KByte. Packets will be allocated by a user mode process, and an MDL will be built to describe this packet. Although the packet size is equal to a page size (32 bit OS) it might be fragment to several locations on the physical memory. A scatter\gather list will hold the description of physical address per fragment. The questions are: 1. What is the size of the smallest fragment? Will it be a byte? 1a. Can I assume what will be the number of fregamnts for 4096 bytes packet (reminder - it was allocates in a user mode application)? 2. Can I set the number of fragments and size? 3. If I set the trasfer length to be 4096 bytes and my packet size is 4096 bytes will a transaction contain one transfer? 4. If the DSP interrupts when a trasfer is completed, however it interrupts in other occasions, can the driver tell the difference? Can I write some logic in the DPC (ISR of course cannot tell the difference) in order to destingwish between two "reasons" of DSP interrupt? 5. Will a 4096 bytes Thank you in advanced for your help!

    - Re: No UINumber being assigned to PCI attached MPS devices in Vista Eliyas, The UINumber is correctly reported on XP. The same computer, BIOS and adapters cards are used in both instances but with different boot drives. The system uses PCI and PCI-X buses. Should there be a difference between XP and Vista? Seems like a bug... We use the UINumber to show the physical position of Adapter cards in systems we ship out. The user can then distinguish between multiple Adapter cards installed in the same system, configure the cards, attach cables, etc.. Needless to say, we will continue to ship our product with XP until we can get everything working properly and with the same performance.

    - Question regarding COM ports I'm trying to use a call to: l = ComDBGetCurrentPortUsage( HComDB, bufBits, 256, CDB_REPORT_BITS, pMaxPortsReported ); to determine if a USB serial port device is plugged in. Before plugging in the device, the device manager reports that I have 2 COM ports and 2 printer ports. After plugging in the device it reports 3 COM ports and 2 printer ports. However, before plugging in the device, a call to ComDBGetCurrentPortUsage fills in the bit array with 05 00 00... and after the call it still returns 05 00 00... (for COM 1 and COM 3) How can I determine if the USB COM device has been plugged in and if it has, what number has been assigned to it? It returns these values even if I powered up with the device unplugged. The call to ComDBGetCurrentPortUsage is in a dll written in 'C++'. The call to the dll is from a routine written in Visual Basic. Thanks for your help -- Regards, Dean Tag: storport requests queue Tag: 95315

    - WdfUsbTargetDeviceSendControlTransferSynchronously from TimerExpired function causes access violation I'm currently writing a KMDF based driver that will upon insertion of a USB device, download firmware to it and then reset the USB bus causing re-enumeration. I'm not entirely clear on the best way to implement this, my current plan is as follows: * From EvtPrepareHardware, I start a timer which causes TimerExpired to be called * In TimerExpired, I do a USB control transfer to check device state, upload a block of data and then set another timer. I thought this should be working, but I'm running into an access violation somewhere in the USB stack, and I'm not sure how to debug this further. When I call this function from EvtPrepareHardware itself, everything works fine, but calling it from TimerExpired causes the access violation. The call stack at that moment is as follows: (using KMDF 1.5) nt!DbgBreakPoint Wdf01000!imp_WdfUsbTargetDeviceSendControlTransferSynchronously+0x186 mydriver!WdfUsbTargetDeviceSendControlTransferSynchronously+0x29 mydriver!TimerExpired Now I have two questions: 1. Should I be using this design or would you suggest a different way? (the protocol requires me to sleep every now and then, and since you can't just use Sleep() I decided to go for the design as described). 2. What could be causing the access violation? Is it not allowed to call USB stack functions from TimerExpired? My TimerExpired function looks something like this: VOID TimerExpired(IN WDFTIMER Timer) { NTSTATUS status; WDFDEVICE Device; PDEVICE_CONTEXT pDeviceContext; WDF_USB_CONTROL_SETUP_PACKET thePacket; BYTE buf[16]; DWORD len, nbytes; WDF_MEMORY_DESCRIPTOR memoryDescriptor; Device = WdfTimerGetParentObject(Timer); pDeviceContext = GetDeviceContext(Device); WDF_USB_CONTROL_SETUP_PACKET_INIT_CLASS( &thePacket, BmRequestDeviceToHost, BmRequestToInterface, 0x05, 0, 0 ); pDeviceContext = GetDeviceContext(Device); WDF_MEMORY_DESCRIPTOR_INIT_BUFFER(&memoryDescriptor, (PVOID) buf, *len); status = WdfUsbTargetDeviceSendControlTransferSynchronously( pDeviceContext- >WdfUsbTargetDevice, WDF_NO_HANDLE, // Optional WDFREQUEST NULL, // PWDF_REQUEST_SEND_OPTIONS &thePacket, &memoryDescriptor, // MemoryDescriptor &nbytes); // BytesTransferred } Tag: storport requests queue Tag: 95314

WDK provides this file in WDK/redist directory . i copied .inf file .sys file and WdfCoinstaller010007.dll file in one directory . using the control panel add new hardware i have installed the driver. but this is not installed the driver properly. it has given this error message: "The specified resource type cannot be found in the image file". if any body have idea to solve this error give suggestion: thanks is advance. sulibsp Tag: storport requests queue Tag: 95313

    - Can we use cpp to write WDM driver ? Hi I found that some WDM audio driver source use cpp files , so can DDK use all C++ class and library ? Can we use other languages (like VB C# Java) to develop Microsoft drivers ? Thank you Tag: storport requests queue Tag: 95311

    - 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: storport requests queue 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: storport requests queue Tag: 95304

    - 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: storport requests queue 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: storport requests queue 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.

    - 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: storport requests queue 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: storport requests queue 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.

    - SMARTCARD_EXTENSION & OsData Hi, The SMARTCARD_EXTENSION structure has a member OsData->DeviceObject. What purpose does DeviceObject server here? Why woul'd smclib need the drivers DeviceObject. -- Vijairaj Tag: storport requests queue Tag: 95223

Hi

I am developing a storport mini-port driver for Vista and I got a strange
problem â?? the storport queues not more than 20 requests against my mini-port
driver; I generated different workloads and under heavy load I can see that
my mini-driver has 20 outstanding requests practically all the time during
the test

Any idea how this limitation gets imposed?

TIA
Andrew

Never mind... 20 looks like a default value before
StorPortSetDeviceQueueDepth gets called
