    - W2K Libraries are corrupted in the WS2008 and Vista RTM releases.. Is there any developer how tried to compile an existing "old" W2K driver in the new WDK RTM releases? IÂ´m almost sure such a test is never made by MS ... Somebody (MS) recompiled a part of the W2K libraries at 1/18/2008 (most of them are created 1/3/2008). Most probably this modification mixed windows XP libraries into the W2K set ... error LNK2019: unresolved external symbol __imp_@InterlockedPopEntrySList@4 referenced in function _ExAllocateFromNPagedLookasideList@4 error LNK2019: unresolved external symbol __imp_@InterlockedPushEntrySList@8 referenced in function _ExFreeToNPagedLookasideList@8 The W2K drivers using the ExAllocateFromNPagedLookasideList, and ExFreeToNPagedLookasideList (for example 4mmdat W2k driver from 2002) cannot be linked anymore. The older WDKs (wxp and ws2003) are working. Is there any plan to renew one time the w2k part and release a consistent set of libraries?

    - IOCTL_SCSI_GET_ADDRESS Hi, I use the msdn sample getaddr.exe on a Win2K3 x64 server with argument scsi6: and it failed with error code 50 (this request is not supported) after IOCTL_SCSI_GET_ADDRESS. Is this by design? Since the program gets correct address if I use PhysicalDrive10 as argument. I need to write a application to discover all the scsi enclosures. and issue Scsi Pass Through command to it. I could find the enclosure and know its bus/target/lun but not the scsi port with the help from another msdn post. I saw a post mentioned to use IOCTL_SCSI_GET_ADDRESS and found the getaddr.exe sample. I tried it and got the above result. Ken Tag: I am struck with configuration file COM port driver Tag: 104540

    - About Power management problem of Legacy NDIS IM Driver. Hello everyone! I'm really new about drivers and working on maintenance NDIS Intermediate driver. The driver has a problem that it prevents the system to get suspended on windows xp. This driver was written few years ago by someone. The driver seems to be written from passthru released on 1992.(very old.) And I have to build it with Windows 2003 Server DDK. And the driver supports NDIS4.0. (I noticed that the passthru of WS2003DDK have been modified here and there from the old passthru. And I'm wondering these changes could be necessary for my legacy driver to handle power-management correctly on windows xp.) I found that my driver gets IRP_MJ_POWER with IRP_MN_SET_POWER when the system is about suspending. (The WS2003DDK's passthru does not get those IRPs.It only gets OID_PNP_SET_POWER on the miniport-edge. why?) I also found that someone blocks forever during the IRP_MJ_POWER handling process. I found this by installing my DispatchPower handler as following. pDefaultDispPower = DispatchTable[IRP_MJ_POWER]; DispatchTable[IRP_MJ_POWER] = MyDispatchPower; MyDispatchPower() { KdPrint(("MyDispatchPower")); Status=pDefaultDispPower(...); KdPrintf(("pDefaultDispPower result=0x%08x", Status)); } The pDefaultDispPower() never return when it gets IRP_MJ_POWER with IRP_MN_SET_POWER. Could you tell me why does it block? Thanks! Tag: I am struck with configuration file COM port driver Tag: 104538

    - default I/O Target & remote I/O Target by WDK 6000, sample driver for 1394: the driver has a default I/O target for each device, which is the device's next-lower driver: ------------------------------------------------------------------------------------------- \src\kmdf\1394\driver\pnp.c deviceExtension->StackIoTarget = WdfDeviceGetIoTarget(device); deviceExtension->StackDeviceObject = WdfDeviceWdmGetAttachedDevice(device); ----------------------------------------------------------------------------------------------------------------------------------------- the sample driver has also a remote I/O target representing port device object so that we can send async requests in rawmode directly to the port device: ------------------------------------------------------------------------------------------- \src\kmdf\1394\driver\pnp.c pNodeExt = WdfDeviceWdmGetPhysicalDevice(device)->DeviceExtension; deviceExtension->PortDeviceObject = pNodeExt->PortDeviceObject; WDF_IO_TARGET_OPEN_PARAMS_INIT_EXISTING_DEVICE(&openParams, pNodeExt->PortDeviceObject); WdfIoTargetCreate(device, WDF_NO_OBJECT_ATTRIBUTES, &deviceExtension->PortDeviceIoTarget); WdfIoTargetOpen(deviceExtension->PortDeviceIoTarget, &openParams); ------------------------------------------------------------------------------------------- So, if I want to use bus & nod number by asyncronous transfer (rawmode), the t1394_AsyncRead function will take as ioTarget the remote I/O target ------------------------------------------------------------------------------------------- ioTarget = deviceExtension->PortDeviceIoTarget; ------------------------------------------------------------------------------------------- in the other case, the t1394_AsyncRead function use the default I/O target as ioTarget and ignore bus & nod number. ------------------------------------------------------------------------------------------- ioTarget = deviceExtension->StackIoTarget; ------------------------------------------------------------------------------------------- I have now a 1394 device with 200 Mpbs for asyncronous transfer, so I have to set Xmit properties with 200 Mpbs and use no bus & nod number.. If I don't set Xmit properites, I get the error 'STATUS_IO_DEVICE_ERROR'. But if I use bus & nod number (asyncronous transfer in rawmode), I get also the error message 'STATUS_IO_DEVICE_ERROR'. It seems like that the set Xmit properties function has no effect if I have asyncronous transfer in rawmode. But why? Could somebody please explain this? Thanks in advance, min Tag: I am struck with configuration file COM port driver Tag: 104532

    - Disable multi core Hi, I use an old driver and a device which was designed 10 years ago. The issue is that they cannot run on a multi-core system. Beside of the solution of designing a new hardware, I thought about an option of disabaling the multi core option of the CPU(s). Is it possible? If so, how can I do it? The relevant OS are server 2003 and server 2008. Thanks, Avi. Tag: I am struck with configuration file COM port driver Tag: 104513

    - DISK_DETECTION_INFO http://msdn2.microsoft.com/en-us/library/aa363965(vs.85).aspx > DetectionType > The detected partition type. > This member can be one of the following values from the DETECTION_TYPE > enumeration. > DetectExInt13 2 The disk has an extended Int13 partition. > DetectInt13 1 The disk has a standard Int13 partition. > DetectNone 0 The disk does not have an Int13 or an extended > Int13 partition. Did someone forget to document this possibility: DetectBoth 3 The disk has at lease one partition of each type. Or if someone forgot to design for this possibility, then what happens? Some PC creates a standard Int13 partition on a hard drive, a second PC creates an extended Int13 partition on the same hard drive, and a third PC calls DeviceIoControl and gets a BSOD? Next: > Int13 > If DetectionType is DetectInt13, the union is a DISK_INT13_INFO structure. > ExInt13 > If DetectionType is DetectExInt13, the union is a DISK_EX_INT13_INFO > structure. Is that so? Earlier on the same page, Microsoft said that the union is a structure of both structures: > union { > struct { > DISK_INT13_INFO Int13; > DISK_EX_INT13_INFO ExInt13; > }; > }; In case of any doubt, the above information is not one per partition, it's one per disk.

    - Blue screen when device object is deleted. I wrote a non device driver to hook ZwCreateFile using SSDT hooking technique. While running one of my test case my system crashed (blued screen). Test case: --------------- During mid of a copying operation if i unload my driver, system crashes (blue screen). Before unloading driver restore the original ZwCreatefile address in SSDT and then destroy device object. As i narrowed down the problem, it crases when device object is deleted. It appears that one of the threads still using my newZwCreatefile and meanwhile driver object is deleted and system crashes. Its what accroding to my understanding. Can anyone give me any idea how to avoid this crash, or its some other reason. Thanks Tag: I am struck with configuration file COM port driver Tag: 104495

    - CreateDevice not getting called in WDDM user-mode display driver Hi All, I'm working on r200umd user-mode sample display driver for Vista and I'm facing some problem after its Openadapter function is getting called. Openadapter is returning status as S_OK. In this call, it is passing pointers of CreateDevice and GetCaps. After this call, GetCaps is getting called but in the WDDM documentation nothing much is mentioned about this function. And inside this function, sometimes I'm getting BSOD after calling 'bDD4DISPInitDD' function inside R200D3DDevInit function. And sometimes GetCaps is getting called repetitively and after some iterations getting crash. But never got a call for CreateDevice. Actually I would like to know what actually GetCaps should return and when CreateDevice will get called and why GetCaps is getting called repetitively??

    - Extracting text from PDF documents for virtual printer driver I'm developing a virtual printer driver, and it handles most documents well. Where it fails is with PDF documents containing east Asian characters. I've found some other posts which mention that Adobe provides glyph indices, rather than unicode characters.

    - do not use CM_xxx function call Hi, I need to discover and know the scsi disk enclosure port/bus/target/LUN numbers. I read some MSDN sample and learn how to enumerate them and can find the disk enclosures attached to my Windows 2003 x64 server. And I use the CM_Get_DevNode_Registry_Property to get the bus/target/LUN of the enclosure, but I could not get the scsi port number. And MSDN mentioned "Do not use..." the CM_ function I used and suggest to use SetupDixxx instead. But they require different input parameters: CM_xxx use "handle of device instance" while SetupDixxx use "handle of device infoset" and "device info data" I think. May someone hint me how to get the parameters used in SetupDixxx from the CM_xx device instance handle? Also how to get the scsi port number please?

    - Drive letter from WdfDeviceCreateSymbolicLink not removed when driver Hi, I'm building something like the ramdisk example in the WinDDK. It uses WdfDeviceCreateSymbolicLink to attach to a drive letter. The problem is that when the driver unloads, the drive letter doesn't completely go away. It remains in Windows Explorer as a disk with a red circle and a white question mark in the middle. The "Map Network Drive" wizard shows the drive letter as available. It completely disappears from explorer after a reboot. Any ideas? I want it to go away completely after the driver unloads.

    - IoGetDeviceProperty returns STATUS_OBJECT_NAME_NOT_FOUND In the AddDevice() handler from our driver for USB device, we call the IoGetDeviceProperty() and it returns STATUS_OBJECT_NAME_NOT_FOUND. We use the same PhysicalDeviceObject given as a parameter in the AddDevice() handler. Can you see one possible reason for this ? Our driver is BDA driver with USB WDM lower edge. The strange thing is that problem occurs only on Windows 2000 platform with USB composite device. On Windows XP/Vista, or if the device exposes only one single USB interface, the call to IoGetDeviceProperty() is successful.

    - KeAcquireSpinLock or KeAcquireSpinLickAtDpc? I have a function that uses KeAcquireSpinLock(). This function will be called for each packet in a data stream at DISPATCH_LEVEL and I was interested to tune the performance. Then I read documentation that KeAcquireSpinLockAtDpc() will improve performance. I also want to use this function in few places where it rarely be called at " less than DISPATCH Irql". I am thinking of using KeGetCurrentIrql() to decide whether I use KeAcquireSpinLock() or KeAcquireSpinLockAtDpc(). I am not sure if I should bother to do this or simply always use KeAcquireSpinLock(). Is the performance be considerable to use conditional KeAcquireSpinLockAtDpc() ?

    - Accessing card in USB card reader I would like to issue an ATA Identity command to a CF card in a USB card reader. I understand that card readers in general (and in this specific case) are using USBSTOR.SYS which is a SCSI interface, so unless I were to make my own driver and have support for that in the unit, I really can't do that. What I can do is send SCSI commands down to the unit, but when I use SCSI passthrough and ask for the identity, I get the identity of the card reader and not the card. Wondering if anyone in this group knows how to access to the card. I understand its possibly vendor specific, but figured it worth a shot here.

    - Memory related questions I have some memory related questions: 1. Is the object and handle allocated from paged/nonpaged pool? If yes, any tag will be there to track? 2. Can any allocation be there in paged/nonpaged memory without tag (even without wdm/ddk tag)? 3. If any handle/object leakage is there, can we catch this with Driver Verfier? I saw that Driver verfier could not find one object leakage (I selected only my driver in Driver Verifier). Or should I select any microsoft driver to catch this? 4. If I map user buffer to a kernel addres space, does it map to the paged memory address or some where else? If yes, does it have any tag?

    - Resetting a CD/DVD writer I've got some code which does low level access to CD/DVD writers using SPTI. That's all fine, except when something goes wrong (usually, sadly, the result of my bugs :( ). Then I'm left with a device which thinks it's busy and I can do nothing to persuade it otherwise (save reboot the machine). What I think I want to do is a device reset, but this seems not to be supported, either as a SCSI command or an IOCTL. How can I reset the device/subsystem so that I can gracefully back out of my error condition and start to re-use the device? (Sample code would be particularly nice) Thanks Iain Tag: I am struck with configuration file COM port driver Tag: 104416

    - Howto increase NT kernel stack size? (if it is possible at all) Is there a way to set the kernel stack size somehow? To increase it by setting some value? In the registry, or elsewhere? The story: It is known the NT stack size to be 12k (approximately). There is a bug of NT when a call to MmGrowKernelStack fail with STATUS_STACK_OVERFLOW. (the bug is concerned with DLL embedding and WH_CALLWNDPROC) There is a hope to somehow overcome the problem if increase the kernel stack size. Thanks. BTW, is the 64bit NT stack size is 12k too (just wonder)? Tag: I am struck with configuration file COM port driver Tag: 104415

    - File System Driver, OLE Structured Storage problems-help! Hi! I'm having a problem in my FSD, trying to support StgOpenStorage. Basically I can create a store okay, but when I go to try and read it with another call to StgOpenStorage call I get the error (0x80030050, already exists). More specifically, I first create a store with STGM_TRANSACTED, STGM_READWRITE, STGM_SHARE_DENYWRITE and STGM_CREATE. The StgCreateStorageEx call works fine with these flags. But then when I try to get StgOpenStorage to work to open that already opened store, I get the error 0x80030050). This works on the FAT file system, but not in my own FSD. I've spent quite a bit of time looking at the activity of StgOpenStorage. When STGM_TRANSACTED and STGM_READ is indicated for an existing open DocFile , it seems like there is a cache read for the existing data, then a bunch of lock ops and then another cache read of size 0x200 with data that starts out as 0xFD 0xFF 0xFF 0xFF.... . Is this the two-phase commit process referred to here <http://msdn2.microsoft.com/en-us/library/aa380017(VS.85).aspx>, where "a table is updated in the file using a single-sector operation to indicate that new data is to be used in place of the old"? When I try this on a regular FAT filesystem, filesys shows the second cache read to be the same as the first (after the StgmOpenStorage is called to open a store that is already opened). When I try this on my own FSD, the second cache read shows the 0xFD 0xFF 0xFF... for the first 512 bytes. The StgmOpenStorage call then fails with 0x80030050 (already exists). What might the StgOpenStrorage be looking at to determine if it can read the opened store, and why should it return the "already exists" error? Why would this first reference for data in 0xFD 0xFF 0xFF... for the first 0x200 bytes in cache happen for my FSD, and not for the FAT FSD (for example?). Please note, I see no additional actual writes that start with 0xFD 0xFF..., but what I see is that in the second cache read, this data mysteriously gets put there, which I interpret to perhaps be the "single-sector operation". Thoughts? Any help with this is greatly appreciated!!! Best, Steve PS To recap, here is what happens in my FSD, and in FAT-pay attention to steps 4,12, and 18: FAT My FSD 1) StgCreateStorageEx - returns OK, 1) StgCreateStorageEx - returns OK, handle is left open (not closed before #2) handle is left open (not closed before #2) 2) StgOpenStorage call to open #1 2) StgOpenStorage call to open #1 3) IRP_MJ_CREATE returns OK 3) IRP_MJ_CREATE returns OK 4) IRP_MJ_READ first 0x200 bytes 4) IRP_MJ_READ first 0x200 bytes buffer looks like 0xD0 CF 11 E0 A1.. buffer looks like 0xD0 CF 11 E0 A1... 5) FileBasicInformation: Attrib ARCHIVE 5) FileBasicInformation: Attrib ARCHIVE (I set the ARCHIVE bit cuz FAT does) 6) FASTIO_LOCK 6) FASTIO_LOCK 7) FASTIO_LOCK 7) FASTIO_LOCK 8) FASTIO_UNLOCK_SINGLE 8) FASTIO_UNLOCK_SINGLE 9) FASTIO_LOCK - 9) FASTIO_LOCK - STATUS_LOCK_NOT_GRANTED STATUS_LOCK_NOT_GRANTED 10) 4 FASTIO_LOCKs 10) 4 FASTIO_LOCKs 11) 4 FASTIO_UNLOCK_SINGLEs 11) 4 FASTIO_UNLOCK_SINGLEs 12) IRP_MJ_READ with DATA the SAME 12) IRP_MJ_READ ,DATA DIFFERENT!!! as #4 Data starts with 0xFD 0xFF 0xFF 13) FASTIO_LOCK 13) FASTIO_LOCK 14) FASTIO_LOCK 14) FASTIO_LOCK 15) FASTIO_UNLOCK_SINGLE 15) FASTIO_UNLOCK_SINGLE 16) FileStandardInformation 16) FileStandardInformation 17) FileBasicInformation 17) FileBasicInformation 18) FastIORead - SAME as #4 and #12 18) IRP_MJ_READ, buffer starts with "Root Entry" 19) IRP_MJ_READ offset 0x1000, all zeroes 19) IRP_MJ_READ, offset 0x1000, 0's 20) IRP_MJ_READ, offset 0x10000, EOF 20) IRP_MJ_READ, offset 0x10000,EOF 21) FASTIO_UNLOCK_SINGLE 21) FASTIO_UNLOCK_SINGLE Tag: I am struck with configuration file COM port driver Tag: 104413

    - Handle call to FlushFileBuffers in UMDF driver Hi, I have a UMDF driver which creates a virtual serial COM port. An application, which calls FlushFileBuffers with a handle to this COM port, receives error 50, which indicates that this request is not supported. The driver for the normal COM port, however, supports a call to FlushFileBuffers, at least this call does not fail. In the KMDF serial port driver example one can find that it handles IRP_MJ_FLUSH_BUFFERS. So I guess I need to implement the corresponding interface in UMDF. However, I was not able to find it. Which interface must be implemented to handle IRP_MJ_FLUSH_BUFFERS. Thanks for any suggestions and best regards, Andre Tag: I am struck with configuration file COM port driver Tag: 104412

    - mapping device memory to userspace through MDL direct io interface I am trying to map the device memory(128MB) to userspace through direct IO interface using MDL's.

I am building the driver using WDF tool kit & trying in Visat-32 bit OS.

    - USB composite device on Window 2000 We have developped one BDA driver for USB devices. The driver is able to handle single interface devices as well as multiple interfaces devices (USB composite devices). On windows XP and Vista platforms, everything works fine. On windows 2000 with single interface devices, it works fine. But on windows 2000 with USB composite devices, we are facing problems in the AddDevice() handler : The call to KsCreateDevice() fails with return code STATUS_INSUFFICIENT_RESSOURCES. One call to IoGetDeviceProperty() fails with return code STATUS_OBJECT_NAME_NOT_FOUND The strange thing is same function calls succeed on Win XP with composite devices or on Win2000 with single interface devices. I'm suspecting something going wrong with the usbhub.sys. Any advise would be appreciated. Thanks Francois. Tag: I am struck with configuration file COM port driver Tag: 104401

    - Supported way for installing NDIS filter driver on Vista Hi, My Windows Installer package needs to install NDIS filter driver on Vista. DIFxApp looks good, because it supports Windows Installer. Does DIFxApp support also installing NDIS filter drivers? I succeeded in installing NDIS filter driver by adding 'DriverPackageType = Network' to the INF file. However, DIFxApp 2.1 doesn't document that anymore. Is there any documented way for installing NDIS filter driver? If not, should I stick with C++ Custom Actions using INetCfg classes?

    - BSOD with user-mode display driver (WDDM) in Vista Hi All, I'm working on r200umd user-mode sample display driver and I'm facing some problem after its Openadapter function is getting called. Openadapter is returning status as S_OK. In this call, it is passing pointers of CreateDevice and GetCaps. After this call, GetCaps is getting called but in the WDDM documentation nothing much is mentioned about this function. And inside this function, sometimes I'm getting BSOD after calling 'bDD4DISPInitDD' function inside R200D3DDevInit function. And sometimes GetCaps is getting called repetitively and after some iterations getting crash. But never got a call for CreateDevice. Actually I would like to know what actually GetCaps should return and when CreateDevice will get called and why GetCaps is getting called repetitively??

    - devcon.exe and unattended install from floppy Hi: I'm using devcon.exe to install a NIC driver in an unattended install from a boot floppy and the vanilla distribution Window XP CD (i.e., not a custom boot CD with answer files,drivers, etc on the custom CD). The problem is that while the finished install shows the driiver installed (in Device Manager), the network information, joining the workgroup (not WORKGROUP), and the attachment to the network printer are not being completed. I'm assuming it's because the network adapter is not being installed early enough in the installation process. Is there some way to get devcon.exe to execute in the text mode setup part of the install, when the txtsetup.oem file is being executed?

    - Obtain FAT32 volume data just as it's done for NTFS Hi. I have problems with obtaining FAT32 volume data. For NTFS there's a FSCTL_GET_NTFS_VOLUME_DATA control code, and nothing similar for FAT32. Actually I need only 2 pieces of information: 1) The offset of the starting sector of the volume from the beginning of the disk; 2) The number of the sectors per cluster, or the number of bytes per cluster. At the first glance you may think it's easy to obtain them using IOCTL_DISK_GET_PARTITION_INFO control code, but the things are somewhat complicated. For NTFS volume the starting sector offset can be obtained easily dividing the starting offset of the partition (in bytes) by the number of the bytes per sector (the mentioned arguments are obtained through IOCTL_DISK_GET_PARTITION_INFO and IOCTL_DISK_GET_DRIVE_GEOMETRY control codes). For FAT32 volumes data sectors start from partition offset + reserved sectors + n*FAT size, and it's impossible to get these arguments through any conrol code. The only obvious way to obtain them is reading sector 0 of the partition, which contains all the necessary data. Unfortunately I have problems with reading exactly sector 0 - a legacy filter driver encrypts/decrypts all read/write operations and it functions incorrectly just for sector 0 read operation, as a result I get garbage. Question: Is there another way to obtain the 2 abovementioned pieces of volume information? Thanks in advance Martin Tag: I am struck with configuration file COM port driver Tag: 104380

    - mapping device memory to userspace through MDL direct io communica I am trying to map the device memory(128MB) to userspace through direct IO interface using MDL's. I have choosen below approach for mapping the memory to user space: IoAllocateMdl for allocating buffer for MDL(with virtual address of the device memory, from MmMapIoSpace) MmBuildMdlForNonPagedPool MmMapLockedPagesSpecifyCache By doing in above method, i have observed that, i could map the memory to only less limit,0x20000, but if i tried to use the full size(128MB), system is giving Blue screen with error as KERNEL_IN_PAGE_ERROR. I am building the driver using WDF tool kit & trying in Visat-32 bit OS.

    - .inf for using usbser.sys with CDC Vcom on Windows 98 My company has a device that uses usbser.sys in WindowsXP/2000/Vista to act as a CDC Vcom port. It works fine in those OS versions. The problem I am having is that when I attempt to use the same .inf file in Win98 I see my device as installed with no problems in device manager but the device never seems to be issued a port number. I have not been able to find any example inf files for USB CDC vcom that use Win98. I have read some documentation on version with XP/2000 that claim that you can use CDC on Win98 by modifying the .inf file. Has anyone used or seen a CDC .inf file for Windows98 that correctly installs a CDC VCOM device and issues it a port number correctly in device manager?

    - [OT] Process Monitor Symbols loading Problem on Windows 2000 Professional,... Hi, i know this is not the NG for this, but even after asking this question on Sysinternals Forum, i did not get a solving answer on this. The Process Monitor does not load/download the symbols for my Windows 2000 Professional System. Any other Application WinDbg, Process Explorer works fine and the configuration is not different from the others, since they all use the same method to get the symbols from MS Symbol Servers. Process Monitor still wont resolve callstack/frames, even there is the pdb files available for the binaries. It also does not download the symbols from MS Sym Server. All other applications work well with ms symbol server. I really dont know what the problem here is. It seems like Process Monitor (i use the latest) does try to access the pdb files with wrong filenames, e.g. instead of using e.g. kernel32.pdb it tries to get the symbols for the kernel32.dll with its original name, which means that it looks for a debugging database file with the extension dll, which for sure does not exist on the server and the local system. But if you like, you can read this thread i started on sysinternals forum, which has more information about: http://forum.sysinternals.com/forum_posts.asp?TID=14076 Any more ideas,...i must apologize, this is my second post here, but maybe someone has a idea on this, after reading the sysinternals posting from me, that has some more information about this s***.
