    - SetupDiCallClassInstaller getting error 0xE000023B on DIF_REMOVE My code uninstalls an NDIS driver with SetupDiCallClassInstaller(DIF_REMOVE,..), much as in the DDK example. On Windows 2003 Server, I get an error 0xE000023B, and can't figure out what this means. The nearest error I could find was STATUS_CONNECTION_ACTIVE (0xC000023B), but that doesn't seem to make sense-- I tried disabling my driver and still get the same error. The same code works fine on Windows 2000 and XP. Anyone know what this error means or what might be causing it? Tag: determine x64 Tag: 75577

    - Device Co Installer and Microsft In Box Drivers I have developed a Device coinstaller that utilizes in box MS drivers based off the DDK toaster sample. Since I cannot redistribute in box drivers how to I have my co installer point to the in box driver without the Files needed box showing up? I noticed if I copy the driver to my distribution folder and tell the installer the location I do not recieve the Files needed box anymore. But leaving the driver in the system32 drivers directory and pointing the driverpath to that directory I get the box Any suggestions? Tag: determine x64 Tag: 75576

    - Sending Irp from SCSI miniport driver to bus driver I have a bus driver similar to the toaster bus driver from the DDK. I create a PDO (by using an application to send IOCTL_BUSENUM_PLUGIN_HARDWARE), and then I load my SCSI miniport driver onto that PDO. My bus driver exports an interface that the SCSI miniport driver uses. In the SCSI miniport code, I want to send IRP_MN_QUERY_INTERFACE to the child PDO that corresponds to the PDO on which the miniport driver is installed. In the miniport code, I have been sending the IRP by using the code below, where targetObject is the DEVICE_OBJECT field of the DRIVER_OBJECT parameter passed to the miniport's DriverEntry function. I believe that targetObject would then correspond to the FDO (not the child PDO that I want), but, nevertheless, this was working with no problems at all. However, I recently switched to another test PC, and now I get Bug Check 0x35 (NO_MORE_IRP_STACK_LOCATIONS) on the call to IoCallDriver. 1) Any idea why I get this Bug Check? 2) Is there a way for the miniport driver to get the PDO pointer that I need? KeInitializeEvent(&event, NotificationEvent, FALSE); irp = IoBuildSynchronousFsdRequest(IRP_MJ_PNP, targetObject, NULL, 0, NULL, &event, &ioStatusBlock); if(NULL == irp) { status = STATUS_INSUFFICIENT_RESOURCES; goto End; } irpStack = IoGetNextIrpStackLocation(irp); irpStack->MinorFunction = IRP_MN_QUERY_INTERFACE; irpStack->Parameters.QueryInterface.InterfaceType = (LPGUID)&ChannelBusProtocolGuid; irpStack->Parameters.QueryInterface.Size = sizeof(CHANNEL_BUS); irpStack->Parameters.QueryInterface.Version = 1; irpStack->Parameters.QueryInterface.Interface = (PINTERFACE)pChannelBus; irpStack->Parameters.QueryInterface.InterfaceSpecificData = NULL; irp->IoStatus.Status = STATUS_NOT_SUPPORTED; status = IoCallDriver(targetObject, irp); if(STATUS_PENDING == status) { KeWaitForSingleObject(&event, Executive, KernelMode, FALSE, NULL); status = ioStatusBlock.Status; } Tag: determine x64 Tag: 75574

    - SP_DEVICE_INTERFACE_DETAIL_DATA Are the following facts trivial? Maybe not trivial enough. In the C and C++ languages, if the name of an array is used in an expression then it usually converts to a pointer type, but not always. Also array types in function parameters usually convert. However, if an array is being defined and storage is being reserved for the elements, then the name of the array is the name of the array itself, and does not convert to a pointer. Let's hope those facts are understood by most device driver writers, so that they don't cause many blue screens. Let's hope. Let's hope those facts are understood by big software vendors who have been known to write device drivers. Oops. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/devio/base/sp_device_interface_detail_data_str.asp says: > DevicePath > Pointer to a NULL-terminated string that specifies the device path.

    - "Driver" or "Interface Object" - yes or no? I am having the following debate: I am trying to convince a vendor that the proper way to provide an interface to their embedded system (that hooks up to a PC using TCPIP) is to provide a software component on the PC (like a driver). For some reason, they are of the oppinion that just providing the syntax for the messages that go back and forth should be enough (i.e. the actual data that corresponeds to a particular message in an agreed format). I believe that it is better software engineering to provide an encapsulation and buffer layer in shape of a software component (such as a DLL etc.). Am I right? Wrong? How do I convince them? Any litterature to refer to? Thanks Tag: determine x64 Tag: 75552

    - PS/2 Mouse Packets and USB Mouse Reports under Windows Vista Hello Everybody, Back in 2004, Microsoft said that Vista was going to support the new WM_MOUSEHWHEEL message for horizontal scrolling (tilt wheel), which implies that tilt wheel data will be part of the standard data packet sent by a mouse to the OS. Does anyone know if any information has been published about the standard PS/2 packet structure for a mouse with a tilt wheel? Will there be any other information contained in the new packet format, such as the 4th and 5th buttons? If there are more buttons, what functionality is expected from them? How should a tilt-wheel PS/2 mouse report itself to the system to inform that it supports the new packet structure? Has any information been published about HID usage pages and usages to be used to transfer tilt wheel values to the OS over a USB connection? Any leads will be greatly appreciated. Thank you!

    - pci expansion support I have finally found some time to rewrite a filter driver for a pci expansion system. Given the product I have a requirment to increase the resource windows of buses that are upstream of my product, because the system may be hot plugged, some BIOSes don't support us, and some of the devices downstream (third party) may require more then the default 64MB/64MB/4K. My driver acts as an upper filter to PCI.SYS. I would like to modify the PCI config space of the upstream buses before PCI.SYS reads them. The information I am looking for is at what point in the process does PCI.sys read the config space before resource arbitration to decide what resources to allocate? I will figure it out through expirimentation, but if someone out there has some street knowledge, or can point me to some relevant documentaion in this area that could save me some time I would appreciate it. The driver I am replacing makes modifications in the IRP_MN_FILTER_RESOURCE_REQUIREMENTS pnp IRP, this is a direction I could go as I have a mostly working example, it just seems like modifying the config space and letting PCI.sys do its job is an cleaner route to take. My worry is that I have somewhat of a chicken and egg dilema as I need pci.sys to make modifications to the config space, but I don't want to make the modifications too late. I want to work within the accepted practices of the OS as I want the driver to support Vista and 64 bit versions as well without too many modifications. Thanks, Brian Tag: determine x64 Tag: 75538

    - Sample Mirror Driver Excel Problem. I believe this problem has been around for some years now as I did find one other posting about it from November, 2002. When the sample mirror display driver that is included with the DDK is loaded (i.e. attached to the desktop), Excel displays the following error when it is started: "Not enough system resources to display completely." I strongly suspect this error is a catch-all for several issues and that the problem here is not necessarily due to the driver's taking resource but with something the driver is, or is not, doing that Excel expects/needs. Note that Excel runs after acknowledging this error message. However, it pops up often, for example when simply clicking on a different worksheet tab. So I am hoping this problem has been solved/identified by now and I would greatly appreciate any information anyone might have about it.

    - Mounting on a directory Greetings, I'm looking for some help with mounting a file system on a directory via SetVolumeMountPoint. I have a file system that I'm porting to Windows. In general it mounts OK, but I have one strange error condition that manifests itself as follows: 1) format a partition with my file system 2) use SetVolumeMountPoint to mount the file system on an NTFS directory << at this point the file system is NOT accessible via the NTFS path >> 3) reboot the system << the file system IS accessible via the NTFS path >> As a variation, if instead of rebooting the system in step 3, I use the Disk Management tool to assign a drive letter to the partition with my file system, it somehow makes the file system accessible via the NTFS path... It feels like my file system is not handling some event properly, but I can't figure out what it is... Anybody have an idea on what's needed? Thanks in advance, -bob Tag: determine x64 Tag: 75497

    - SetupDiCallClassInstaller Intiating driver install then failing. Hi, this question has to with the installation and loading of a driver. The installation code I've written works great for Windows XP but not for Windows 2K. I used w2k for the building with the latest DDK. There is no hardware involved so my application calls the Setup API functions to communicate with the PnP Manager. So the adding of the devices is done when a user adds another port, not when the user installs the software. These devices are enumerated in ENUM\ROOT\PORTS. I have a virtual serial port (Com Port) driver I've written that can have up to 255 virtual devices. I have the .inf file and the .sys file in a subdirectory of my application. When I add the first port from my application it gets to the SetupDiCallClassInstaller function and it is called. The PnP Manager then loads my driver and calls DriverEntry. DriverEntry returns STATUS_SUCCESS but the PnP Manager calls my unload routine right after this. SetupDiCallClassInstaller returns stating a reboot is required. On Windows XP the AddDevice routine is called after the successfull call to DriverEntry with no request for a reboot. If I do reboot then everything works great. What is different from wxp and w2k in this scenario? Is there something in the deviceobject that needs to be set. I have Debug Prints in the PnP dispatch routines and none are being called. setupapi.log looks like this: @ 13:54:31.914 : Install Device: Begin. @ 13:54:31.914 : Doing full install of ROOT\PORTS\0000. @ 13:54:31.914 : Install Device: Writing BASIC Logical Configs @ 13:54:31.914 : Install Device: Changing registry settings specified by INF(s). @ 13:54:31.924 : Install Device: Writing driver specific registry settings. @ 13:54:31.924 : Install Device: Installing required Windows services. @ 13:54:32.785 : Install Device: Writing drive descriptive registry settings. @ 13:54:32.795 : Install Device: Calling RunOnce/GrpConv items. @ 13:54:32.795 : Executing RunOnce to process 5 RunOnce entries. @ 13:54:32.815 : Device install finished successfully (ROOT\PORTS\0000). @ 13:54:32.815 : Install Device: End. @ 13:55:02.017 : Device install function: DIF_PROPERTYCHANGE. @ 13:55:02.027 : Executing class-installer. @ 13:55:02.027 : Completed class-installer. @ 13:55:02.027 : Executing default installer. @ 13:55:15.166 : Device required reboot: Device has problem: 31. @ 13:55:15.176 : Completed default installer.

    - Memory manager writing pages back to executables... I was reading an article posted in code project website. The author has noticed that his XP explorer was taking about 5 seconds to display an error message when he tried deleted a locked file or directory. He found that shell32.dll was looping around sleep for 5 times with 1 second expiration. So he decided to patch the shell32.dll using a driver so that it will loop for 0 times thus avoiding the delay. He writes "Now that we know which addresses to patch, we need to map those addresses into the kernel-mode area of the memory. This will allow us to lock the pages in memory, thus preventing them from being swapped out to disk. In this case the memory we're modifying is "backed" by shell32.dll. If it were to be swapped out, the memory manager would attempt to write the changes back to shell32.dll. ...." He also writes (in the Some Final Thoughts section) "I'm not sure why the memory manager doesn't try to write the modified pages back to shell32.dll. I suspect that it's because the entries in the Page Frame Number Database representing the physical pages we've modified always have a "reference count" of at least 1 (because they're locked). If my understanding is correct, this means they will not be moved to the "Modified List" and thus will not be written to disk by the Modified Page Writer. If anyone can expand on this, please leave a comment. " My question is: 1. Is it true that the memory manager will write pages back to the executable upon modification? Under what circumstance does the memory manager does this? 2. Where can I find more information about this topic?

I'm asking this question 'cause I'm trying to compile DDK driver sample and getting the errors. If I do this from command line using DDK's build.exe I get the next: BUILD: Compile and Link for i386 BUILD: Compiling and linking d:\work\msddk\ntddk\src\video\miniport\mirror BUILD: NMAKE.EXE failed - rc = 2 BUILD: Done Tag: determine x64 Tag: 75443

    - Difference between Windows NT 5.0 and NT 5.1 booting process Hi all, I'm working on a full disk encryption driver for which I have written a lower filter to disk driver and some 16 bit assemby program (INT13 hook) which will initially decrypt all the system files. All my modules are working fine in Windows 2000 but in Windows XP it crashes with the following bug check code. PROCESS1_INITIALIZATION_FAILED (6b) Arguments: Arg1: c000007a, Indicates the NT status code that caused the failure. Arg2: 00000006, (reserved) Arg3: 00000000 Arg4: 00000000 Is there any differnence in the booting process of Windows 2000 and Windows XP in terms of reading the data from the disk at boot level.

    - Understanding NdisMAllocateMapRegisters Hi Is it required to call NdisMAllocateMapRegisters before the ndis miniport calls NdisMAllocateSharedMemory(). (as documented in the ddk)? Can't the physical address returned by calling NdisMAllocateSharedMemory() passed to the dma master on the device? My understanding is - if an Ndis Buffer passed by protocol drivers has to be mapped directly and passed to the dma master, then a NdisMStartBufferPhysicalmapping() should be called. To do this, a map register is required, hence NdisMAllocateMapregisters() should be called prior to calling NdisMstartBufferPhysixcalmapping(). But if the buffer passed by the protocol driver is copied to a buffer alloacted using NdisMAllocateSharedMemory(), then NdisMAllocateMapRegister () is not required. Please correct me if Im wrong. basically, What does NdisMAlloacteMapRegisters() do and how and when should an ndis miniport use it.? Thanks in Advance, suu. Tag: determine x64 Tag: 75430

    - CreateFile returns INVALID_HANDLE_VALUE I'm a newbie playing with implementing the filter control device object that is described in the Microsoft Q262305 KB article and the Oney book (Chap 16). I'm working with a USB keyboard driver stack that actually belongs to a barcode scanner (which provides keyboard scan codes as input). I've successfully played and manipulated kbfiltr.sys to intercept the barcode scanner input and put it in a device extension buffer. I've now spent some time trying to mesh the toaster/filter "control device object" code with the kbfiltr example. The resulting upper filter driver compiles and installs. The named "control device object" (MyBarcode) appears in the Winobj utility's "\Driver" folder. The name also appears in the !devstack for the device object shown below. However, when I make the CreateFile call from my user-mode app, it's always failing. Here's the CreateFile call: HANDLE hdevice = CreateFile( _T("\\\\.\\MyBarcode"), GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL); Any ideas would be appreciated. 1: One thing I just thought of is that the name of the control device object is the same as the executable.

    - User mode winmm driver sample needed! Greetings! I want to write a virtual audio device driver to capture the sound output of another windows application. I have come across previous posts in this news group http://tinyurl.com/862cv http://tinyurl.com/8ssl6 that suggest writing an old-style winmm user mode driver using a wodMessage callback. This sounds like exactly what I want. The problem is that I would really need some working sample code to get started, otherwise I would have no idea how to structure such a driver. Even though the MS documentation tells you some things about how to go about it, I don't quite feel that I get what I need to start writing code just by reading the DDK help files... I have looked in the samples provided with win98DDK as well as the latest DDK, but to no avail... Can anybody point me to, or provide me with some sample code for this? I would be extremely grateful! regards - Jonas Tag: determine x64 Tag: 75394

    - Problem with WdfRequestRetrieveOutputMemory Hello to all, I'm developing a driver for an USB device using KMDF. This is my problem (please, evaluate also my approach): I want my driver to be completely asynchronous, in order to do so, I process DeviceIOControl requests in this way: when a new request arrives, I create a new WDFREQUEST using this code: WDF_OBJECT_ATTRIBUTES_INIT_CONTEXT_TYPE(&_object_attributes, MY_IOCTL_CONTEXT); WdfRequestCreate(&_object_attributes, NULL, &_tx_request); In the context structure I store original user mode request and an offset. I create a new WDFMEMORY object using this code: WDF_OBJECT_ATTRIBUTES_INIT(&_object_attributes); _object_attributes.ParentObject=_tx_request; WdfMemoryCreate(&_object_attributes, PagedPool, MYMEMTAG, _tx_buffer_size, &_tx_memory, &_tx_buffer); _tx_buffer_size is larger than original request input buffer because I need to add some protocol bytes. After, I write the request to bus driver using this functions: WdfUsbTargetPipeFormatRequestForWrite(_tx_pipe, _tx_request, _tx_memory, NULL); WdfRequestSetCompletionRoutine(_tx_request, _my_tx_completion_routine, NULL); WdfRequestSend(_tx_request, WdfUsbTargetPipeGetIoTarget(_tx_pipe), NULL); In _my_tx_completion_routine first, I verify if all gone right, if yes: I've to read device response considering that I have to remove protocol bytes and some other informations that are not interesting for user mode application; I use this code (we are always in my 'write phase' completion routine): WDF_OBJECT_ATTRIBUTES_INIT_CONTEXT_TYPE(&_object_attributes, MY_IOCTL_CONTEXT); WdfRequestCreate(&_object_attributes, NULL, &_rx_request); Next, I copy IOCTL context structure received as parameter (it contains the original user mode request and its response buffer offset): _new_ioctl_context=WdfObjectGetTypedContext(_rx_request, MY_IOCTL_CONTEXT); RtlCopyMemory(_new_ioctl_context, _tx_request_context, sizeof(MY_IOCTL_CONTEXT)); I create a new WDFMEMORY object that will be used to read from device: WDF_OBJECT_ATTRIBUTES_INIT(&_object_attributes); _object_attributes.ParentObject=_rx_request; WdfMemoryCreate(&_object_attributes, PagedPool, MYMEMTAG, 512, &_rx_memory, NULL); Keep in mind tha last code line because I'll return on it later. Always in my 'write phase' completion routine I attempt to read from device using this code: WdfUsbTargetPipeFormatRequestForRead(_rx_pipe, _rx_request, _rx_memory, NULL); WdfRequestSetCompletionRoutine(_rx_request, _my_rx_completion_routine, NULL); WdfRequestSend(_rx_request, WdfUsbTargetPipeGetIoTarget(_rx_pipe), NULL); At this point I free the write request using WdfObjectDelete() and I leave _my_tx_completion_routine callback. Once device responds, _my_rx_completion_routine callback is invoked: from status block I verify that read request was completed fine and that I received from device the expected amount of data. The 'Request' parameter is the read request that I've created in my 'write phase' completion callback; and now, finally, the problem: before complete the original user mode request, I've to copy to its output buffer the data that I've received from device excluding protocol bytes. When I use WdfRequestRetrieveOutputMemory on 'Request' parameter to parse received data, it always fails due to STATUS_INVALID_DEVICE_REQUEST error. But, the stranger things must still arrive; in order to avoid the problem I have tried the following: do you remember the WdfMemoryCreate call in _my_tx_completion_routine callback? If I replace the NULL last parameter with a pointer to a buffer (in order to store output buffer pointer in the context structure instead of using WdfRequestRetrieveOutputMemory) a bug check occurs and my test machine restarts. All parameters supplied to WdfMemoryCreate are valid (except for the last parameter that is currently a reference to PUCAHR _buffer=NULL). It is still not the end: if I bring back to NULL the WdfMemoryCreate call last parameter, and exacly below I use WdfMemoryGetBuffer, I obtain a pointer that, once stored in the context structure, when _my_rx_completion_routine is invoked, stores the data received from the device. At this point I can complete the original user mode request correctly. What's wrong with first attempt using WdfRequestRetrieveOutputMemory? What I'm mistaking? Thank you for the patience.

    - STATUS_PENDING returned by lower driver for IOCTL_INTERNAL_USB_SUBMIT_URB Hi All, I have the following code (SendAwaitUrb) that I got from W. Oney's book. I like this book, very useful, a lot of samples, just a great educational source about USB drivers! Probably I do something wrong because my IoCallDriver always return STATUS_PENDING. I call SendAwaitUrb and IoCallDriver from within my Lower function filter driver. I attach the filter driver below the function driver and I am expecting to be able to send Irp with URB to the bus driver. I am a bit concerned about the code pdx = (PDEVICE_EXTENSION) fdo->DeviceExtension; In my filter's AddDevice function I have successfully attached the filter to the driver stack like this: pdx->NextLowerDriver = IoAttachDeviceToDeviceStack ( fdo, pdo). I do IoCallDriver in SendAwaitUrb function like this: IoCallDriver(pdx->NextLowerDriver, Irp); I will be very thankful if you can help me identify the error. Here is the code of the function: #pragma PAGEDCODE NTSTATUS SendAwaitUrb(PDEVICE_OBJECT fdo, PURB urb) { // SendAwaitUrb PIO_STACK_LOCATION stack; IO_STATUS_BLOCK iostatus; KEVENT event; NTSTATUS status; PIRP Irp; PDEVICE_EXTENSION pdx; PAGED_CODE(); ASSERT(KeGetCurrentIrql() == PASSIVE_LEVEL); pdx = (PDEVICE_EXTENSION) fdo->DeviceExtension; pdx->NextLowerDriver = TopOfStack; KeInitializeEvent(&event, NotificationEvent, FALSE); Irp = IoBuildDeviceIoControlRequest(IOCTL_INTERNAL_USB_SUBMIT_URB, pdx->NextLowerDriver, NULL, 0, NULL, 0, TRUE, &event, &iostatus); if (!Irp) { KdPrint((DRIVERNAME " - Unable to allocate IRP for sending URB\n")); return STATUS_INSUFFICIENT_RESOURCES; } stack = IoGetNextIrpStackLocation(Irp); stack->Parameters.Others.Argument1 = (PVOID) urb; status = IoCallDriver(pdx->NextLowerDriver, Irp); if (status == STATUS_PENDING) { KeWaitForSingleObject(&event, Executive, KernelMode, FALSE, NULL); status = iostatus.Status; } return status; } // SendAwaitUrb Best regards, Dim Tag: determine x64 Tag: 75389

Hi,

I need to determine which version of my driver to load depending of if it is
a 32-bit or 64 bit OS. What's a reliable way to determine if I am running on
some x64 version of windows. I could always check the OS version with
GetVersionEx but that doesn't seem reliable.

Thanks

GetNativeSystemInfo is a good way to tell if you are running on x64 in
general. However, there are better ways to do driver installation than
calling GetNativeSystemInfo and having two packages, you should read what
Pavel A posted for specifically driver installs.
