    - WavePci DmaChannel problem for MSVAD. Hi, I am new to Device Drivers. I am trying to replace WavePci in place of WaveCyclic in MSVAD. I am understanding WavePci implementation from sample AC'97. But since it is a real hardware driver with use of DMA,register etc.. So how can I avoid these DMA related code. like 1. It requires AdapterObject. which is created by DmaChannel->GetAdapterObject(); and DmaChannel is created by Port-> NewMasterDmaChannel(); (see driver\wavepciminiport.cpp) 2. In RevokeMappings() implementation we need index of stBDList. (see driver\wavepcistream.cpp) // Get current index nCurrentIndex = Wave->AdapterCommon-> ReadBMControlRegister8 (m_ulBDAddr + X_CIV); I couldn't figure out from where this register gets value.i.e. who writes currentIndex on this register ? And If I want to do it without actual register how can I do it ? I also have question on device powerstate used in AC'97 sample. In PowerDevice2/3 case why MoveBDList is used ? Since I cannot add this implementation in my virtual driver will affect on functionality of the driver. Thanks in Advance. Tag: Upper Filter Drivers. Tag: 109022

    - NDIS driver not working in Vista.- Dropping UDP packets to port 3859 I have a wimax NDIS driver for a WiMax card, which works perfectly in Windows XP. I have a diagnostics application which listens to the UDP port 3859 and prints all the information received from this UDP packets in Win XP. But when i freshly install this driver and application in Windows vita the application does not show anything (looks like its not receiving any UDP packet). But the data path seems to be alright, that is once the WiMax card connects to the base station and then does some operations with the machines connected on the other side of the base station, this diagnostics application also starts receiving the UDP packets from the wimax card in the PC, and shows the information. What could be the issue ? I've not yet started debugging by putting the prints in the NDIS to see where the packets are getting dropped... before that thought of posting this for an expert advice...

    - USB RNDIS Device Speed Hi, I have a USB RNDIS network device, which when connected to windows machine shows a network connection. The windows RNDIS driver queries OID_GEN_LINK_SPEED from device, what speed shall device return? I am asking this question because:- My device is a high speed device which means link speed is 480 Mbps. But since my device implements BULK endpoint, the bandwidth allocated to it will be 10% i.e Maximum 48 Mbps. Now If I say the speed is 480 Mbps what will windows use it for? Will the data transfers from window happen at speed of 480 Mbps or this OID property is just to show the link speed in network connection status window. If windows use this value to do the know the data transfer rate the performance will be hit because due to bulk endpoint Controller will never allow more that 48 Mbps data transfer. Can somebody help? Navneet Tag: Upper Filter Drivers. Tag: 109019

    - SetupDiEnumDeviceInterfaces - DIGCF_ALLCLASSES not returning USB A With C# - VS2008 Pro - Trying to access access USB Audio Device (Alesis Midi Trigger I/O) for read only purposes... XP SP2 Device Manager shows device under "Sound, video and game controllers" as "USB Audio Device" working properly. I'm not finding this device when calling SetupDiGetClassDevs & SetupDiEnumDeviceInterfaces. I tried to pass null for ClassGuid param of SetupDiGetClassDevs as Windows Driver Kit docs suggest. Also tried Windows Driver Kit doc example - SetupDiGetClassDevs(NULL, NULL, NULL, DIGCF_ALLCLASSES | DIGCF_PRESENT). Also tried an unconfirmed ClassGuid value I found defined on web as USB Raw Device class guid {a5dcbf10-6530-11d2-901f-00c04fb951ed} No success on any attempt. No errors. No devices returned on subsequent SetupDiEnumDeviceInterfaces call. Is there another way I can access this device, for read only purposes, using the Device Instance ID listed by Device Manager? As a sanity check, I was able to use the guid returned by HidD_GetHidGuid of hid.dll.... SetupDiGetClassDevs & SetupDiEnumDeviceInterfaces seems to successfully return info on usb HID devices only. I don't think Sound, video and game controllers are HID. Any input is greatly appreciated. Tag: Upper Filter Drivers. Tag: 109009

    - PreInstaller with DPInst Fails Respected Sir/Madam I am working preinstalled to be worked on WindowsXP and for Window 2003. I am using DPInst.exe for preinstallation purpose/ I created test certicate as per procedure Kernel-Mode Code Signing Walkthrough document. Used this test certificate to Sign the drivers. And test preinstall it and it worked fine on test enviournment. After plugging PNP device it get automatically detected and driver get installed fine. We go ahead and purchased a Authenticode Certificates. Then using those Autheticode Certificates I sign our drivers and test it. I found that same drivers does not work. After installation when I plug device it shows Found New Hardware. I am working lot to solve this issue but still not able to success. It would be great if someone can help me.

    - IOCTL access to the HIDCLASS Hi, On MSDN, I found a desciription that HidD_GetAttributes and HidD_GetPreparsedData API will generate IOCTL for HIDCLASS. Here, we can get the USB HID products VID/PID information also by calling the SetupDiGetDeviceRegistryProperty API, not calling the HidD_GetAttributes. They also calls IOCTL for HIDCLASS or other drivers ? I would like to know following code will generates IOCTL to HIDCLASS. hDevInfo = SetupDiGetClassDevs( &guid, NULL, NULL, DIGCF_PRESENT | DIGCF_DEVICEINTERFACE ); // 1) if ( INVALID_HANDLE_VALUE == hDevInfo ) { return FALSE; } for ( Loop = 0; ; Loop++ ){ devinfo.cbSize = sizeof( SP_DEVINFO_DATA ); devinfo.ClassGuid = guid ; if ( !SetupDiEnumDeviceInfo( hDevInfo, Loop, &devinfo ) ){ SetupDiDestroyDeviceInfoList(hDevInfo); break; } if ( !SetupDiGetDeviceRegistryProperty( hDevInfo, &devinfo, SPDRP_HARDWAREID, &dwType, byBuffer, sizeof(byBuffer), &dwSize )){ break; } } SetupDiDestroyDeviceInfoList(hDevInfo); Tag: Upper Filter Drivers.

    - Exposing multiple logical devs per physical dev to ATAPORT I need to present a single physical device as two logical devices (one non-disk ATAPI dev and one ATA disk dev) to VISTA ataport.sys I plan on faking 2 devs on a single channel (not going to expose 2 virtual "channels" w/ 1 dev on each since they will actually map to a single underlying set of hw resources that requires synchronized access but Ataport has no provision for inter-channel synchronization) My controller has a proprietary interface. I plan on reporting it as Native Mode ATA controller since I can't have 2 devs on a single port (ie "channel") on a SATA controller w/out Port Multiplier (don't want to have tofake port multiplier!). My controller I/F supports overlapped cmds (between devs) and queued cmds (multiple concurrent cmds per dev). Questions: 1) If I set NumberOfOverlappedRequests in the IDE_CHANNEL_CONFIGURATION_STRUCTURE to MAX_REQS, will ATAPORT send me up to MAX_REQS concurrent reqs to do with what I want or do I also need to set NumberofOverlappedRequests (in the IDE_DEVICE_STRUCTURE) on a per dev basis? 2) How is fairness between the 2 reported devs managed? I'm guessing Ataport will send a given IRB to the miniport as long as a) the MAX per-channel threshold has not been reached and b) the MAX per- device (for the dev the IRB is addressed to) has not been reached. If so, seems it's the miniport's responsibility to manage fairness/ avoid dev starvation by either a) evenly dividing the total actual queue depth of the physical dev between the 2 logical devs in the per- dev NumberOfOverlappedRequests reported values...or by using AtaPortDeviceBusy/AtaPortDeviceReady judiciously to allow the under- serviced device to receive some IRBS if they are available. Is this a reasonable conclusion? 3) Do I also need to report support for ATA Overlap Feature Set and Queued Feature Set (not to be confused w/SATA NCQ) on the fake ATA dev to convince ATAPORT? Little support for ATA legacy cmd queuing in industry I think so not sure if ATAPORT would care about this ... 4). Will ATAPORT make any adverse assumptions about my HW capabilities because it isn't SATA (and thus doesn't support various SATA advanced features) in performance/power management/PnP/etc area(s)? I know this is a vague question but my concern here is whether there may be any unfavorable caveats related to how ATAPORT behaves w/respect to (P) ATA vs SATA above and beyond whatever is strictly required by underlying technical differences. 5) If I return "type unknown" (0x1f) in SCSI inquiry data on behalf of fake non-disk dev, will ATAPORT be willing to create a PDO on behalf of that peripheral device type as long as the peripheral qualifier is 0 (ie, indicates "A peripheral device having the specified peripheral device type is connected to this logical unit.")? 6) this issue is unrelated to multiple logical devs per physical dev: I need to propogation some private data on a per IO request basis down to the miniport for the non-disk dev. To accomplish this, I thought I would report support for 16 byte command packets (in Atapi Identify Packet Device data) and then just use some of those bytes for my private data instead of an actual "CDB". Is it safe to assume ATAPORT will not try to interpret the CDB and will just copy the 16 bytes into IRB and send me an IRB_FUNCTION_ATAPI? If any of the issues above are blockers, maybe I need to switch to STORPORT model (faking logical devs is common & decoupled from transport/capability issues). Already have the ATAPORT miniport written so would like to avoid this if possible... thanks in advance for any help/info Tag: Upper Filter Drivers. Tag: 108958

    - Not woking Driver Code Signing authenticode but working fine Test Hello All, I am working on making unattended Silent preinstall(Software First) of driver using DPInstall. Drivers to be installed XP Professional. As mentioned by microsoft I signed Drivers with test certificates. On test machine I installed that test certificates in Trusted Root and Tusted Publisher. And my driver preinstall works and drivers go to driver store. Later when I attach device drivers get automatically installed. After that we purchase Code Signing certificates from GlobalSign and I then Sign the working drivers with authenticode certificates. Add certificates in trusted root and trusted publisher. And what I found divers does not get preinstall properly. Drivers go to driverstore properly but when I attach device it shows found new hardware dialog box. When I look Setupapi.log it gives error something like this is not a valid certificate(not exactly remember). But after that it does not create cat file and also pnf file. Please help me to figure out why driver is working with test certificates and not properly signed certificates. Thanks in advance Prashant Tag: Upper Filter Drivers. Tag: 108925

    - SQLite in user mode application of minispy sample? Hi, I am trying to modify the minispy sample from the latest WDK to log file operations to the file database SQLite (sqlite.org) instead of to a simple file. The sources (.h and .c) as well as a compiled version (dll) of sqlite are available. Now I did the following: I created a lib to implicitly load the sqlite dll-library in the user mode application. I added some sample code in the user mode application. The sample works in a standard Win32 console application. I added the sqlite lib file to the file sources of the user mode application (TARGETLIBS) and also updated the include path. My build environment is: Windows Vista and Windows Server Longhorn x86 Free Build Environment Compilation works fine but during link the used functions from the sqlite library remain unresolved. I tried to change the path to the library to include target architecture (i386) but I had little success. I cannot see any useful error messages, even when running the generated nmake command line in verbose mode. What am I doing wrong? Is it at all possible to use sqlite as is in the user mode application? If it is possible, what is the correct way of doing it? What are the requirements for using such dlls? Kind regards, Bjorn Tag: Upper Filter Drivers. Tag: 108896

    - How do I uninstall older USB PnP drivers before installing new one Hello. Our company makes a series of USB-based measurement devices that we talk to via a WDM USB driver we wrote (and logo certified) several years ago. We are in the process of changing over to using WinUSB.sys as our USB access method. When we install the WinUSB.sys access method (via an .inf file) , we would also like to uninstall our old driver's oem*.inf file and .../enum/USB registry entries. My present technique is to: 1) Walk through all of the oem*.inf files and find the one that belongs to us (by looking for our .cat file name in the .inf file). 2) Remove it via the SetupUninstallOEMInf( ) call. 3) Install our new driver via the SetupCopyOEMInf( ) call. While this seems to take care of the .inf and .cat files, it doesn't remove the associated HKLM\SYSTEM\CurrentControlSet\Enum\USB items. This prevents the new driver from being loaded when our device is plugged in. My questions are: Am I doing this the correct way? What is the 'official' method of getting rid of the associated registry entries? Can I just delete them directly using the Win32 Registry API, or will there be security issues? Can I count on the Windows oem*.inf always being named <windows path>\inf\oem*.inf, regardless of the system locale? Thank you Scott Wild Tag: Upper Filter Drivers. Tag: 108879

    - Enumerating empty/unpopulated PCI slots Greetings, I would like to be able to enumerate empty PCI slots present in the system. I am able to enumerate system devices using Configuration Manager and SetupDiXXX functions. I am trying to figure out how to find if a PCI slot is empty or unpopulated, ie, no card is plugged in. In attempt to understand, I checked in Device Manager with different views such as devices by connection, by resource, etc., and looked in the registry to see if I could tell if Windows somehow keeps record/ indication of unpopulated PCI slots. I couldn't find out. Windows is 2003 Server. Need some pointers on how to accomplish this. Thanks. Tag: Upper Filter Drivers. Tag: 108875

    - AVStream Filter Friendly Name If there are multiple devices in a system (KSDEVICE), and each device registers a filter factory with the same KSFILTER_DESCRIPTOR, then there is no way to distinguish a filter on one device from another with the friendly name. It is possible to work around this problem by using a different ReferenceGuid in the KSFILTER_DESCRIPTOR on each device. This is not a good solution, because it is not scalable, as it requires entries in the .inf file for all possible devices in a system. Is there a way to assign a unique friendly name to each filter factory without using the .inf? Thanks for your suggestions. Harry Tag: Upper Filter Drivers. Tag: 108872

    - USB device detection via query registry information Besides using the WM_DEVICECHANGE to detect a USB device insert/remove, I tried to use scan registry information ""HARDWARE\\DEVICEMAP\\SERIALCOMM" to check, and using CreateFile() to open USB com port right after I find a new-coming device. So far, the method works fine in single-core PC while in dual-core PC, I found that if I invoke CreateFile() right after I find the device from registry, the operation will return error code 2 (implying that "The system cannot find the file specified."). If I delay to invoke CreateFile() by sleep(1), for example, the error will not occur again. Thus, I am wondering how the initialization process of underlying driver actually work. Is registry update operation finished before the the device driver is ready? Thanks! Tag: Upper Filter Drivers. Tag: 108847

My concern was, does DTM have the feature of logging the standard output, i.e the standard output that is sent to the console. Can you please advice me, on how to capture it.

    - VisualStudioDeployment-driverInstallation-ArchitectureDifferentiat Hi, I am using Visual studio deployment project for installing my driver using DIFx DPInST tools, as part of this, my package should support multiple OS along with X86 & AMD64 platforms. I really dont want to provide two different msi files to the user for different platforms, instead, I am using x86 platform selection and while deploying the all necessary files(sys, dll, inf & other) using Condition statments. I also aware that, for 64 bit platform, files will be installed in programFiles(x86). Question: I have used the processorArchitecture property to detect the platform, x86 or AMD64, but i have observed that, this condition is not working properly and few files of x86 will be installed in AMD64 platform and some files of AMD64 will be installed on x86 platform. I have double checked that, condition is used correctly for files as ProcessorArchitecture = X86 ProcessorArchitecture = AMD64 To fix this, instead of using processorArchitecture property i am using versionNT & versionNT64. Since many OSes are supported, conditions are becoming very lengthy. And also for detecting VistaX86, i should give below. versionNT = 600 And VersionNT64 <> 600 , if i just use versionNT only, again it is a problem that, in 64 systems, x86 files are copied. But i really didnt like this, when processorArchitecture is used, while copying DPINST for x86 platform, instead of this, AMD64 DPINST was copied. Is there any other property available to detect the architecture or any other method available to detect the host configuration? My requirment is one MSI file shouls support all platforms & configurations to install my driver & appplication. Thanks, Kota. Tag: Upper Filter Drivers. Tag: 108821

    - GetLastError / SetLastError functionality from inside a driver Hi, Please cooperate if this appears to be a trivial question. I am newbie to this. I just wanted to know how is it possible to get functionality similar to GetLastError() and SetLastError() inside a driver? If there is something more particular about a file system filter driver, please advise me about that too because i am working on a file system filter. Thanks for any help. Regards, Aman.

    - error calling PsLookupThreadByThreadId in thread creation callback I'm trying to keep track of new threads with a simple driver by registering a thread creation callback using PsSetCreateThreadNotifyRoutine. The WDK documentation says "In the notification callback routine, the file system filter driver can use the passed in ThreadId parameter and call PsLookupThreadByThreadId to locate the ETHREAD structure." However, this does not work for me, and calling PsLookupThreadByThreadId (or ZwOpenThread) always returns STATUS_INVALID_PARAMETER. I've seen a few other postings on the web with a similar problem. Could this be a documentation error and not possible at all? or maybe I missed anything in the code (note that my driver is pretty simple and not a file system filter driver, but this should not matter, right?)

    - Need help with Network Location Awareness on Vista I work on a VPN client that runs on Vista. We are a TDI filter (yes, I know TDI is going away post-Vista) and we also have a virtual network adapter. The problem I am having is that when my VPN client is loaded, Vista's NLA claims that the machine is not connected to the Internet. The globe is missing from the network icon in the taskbar notification area, Network and Sharing Center shows a red X in the diagram in the connection to the Internet, and INetworkListManager::get_IsConnectedToInternet returns FALSE. This is more than just a cosmetic issue as apparently Google Desktop's News gadget on Vista relies on NLA indicating Internet connectivity in order to retrieve news headlines from the Internet. If my virtual network adapter signals a media disconnect to NDIS, then NLA thinks that the machine is connected to the Internet (via the physical adapter). When my virtual network adapter once again signals a media connect to NDIS, NLA thinks that we are no longer connected to the Internet, even though the system can access the Internet just fine through our VPN via IE, ping, etc. My question is, how does INetworkListManager and/or NLASVC detect Internet connectivity? When my adapter indicates media connected, I see ARP and DHCP requests to my virtual adapter but we handle these and answer them successfully, just like what happens with the real physical adapter. And I don't see requests for any OIDs when my virtual adapter connects, at least not for any that we say we support. Is there a new OID or NDIS request or other such API that I need to handle? Any help would be greatly appreciated! Thanks. Tag: Upper Filter Drivers. Tag: 108732

    - Surprise removal of keyboard device waking from S3 We have a USB keyboard that we have written a filter driver for. The filter driver creates a raw PDO to enable side-band communication with an application through an IOCTL interface. When we put the system in S3, and then wake it up, the keyboard is sometimes experiencing surprise removals. When this happens, the filter driver is not able to clean up properly because the application still has an open handle to it. So AddDevice gets called a second time because the device is suddenly detected again, and things get bad from there. A few questions: 1) what would cause a surprise removal, and then re-detection of a USB keyboard during wake? 2) apart from the filter driver, it seems that Windows can gracefully handle the surprise removal and re-detection of the keyboard device. How is it that Windows can handle this? Does the component that communicates with the keyboard stack get notified that the device was removed, and notified again when the device comes back? Is there a way to implement this same type of behavior in our sideband PDO and application? Thanks, Michael Tag: Upper Filter Drivers. Tag: 108721

Hi All,
I am new to device drivers field. I am trying to build Upper filter
driver for USB device. After installing I verified stack using device
tree. I found my upper filter has created seperate stack just like
PartMgr used to create. I am able to get all PNP related IRPs. But I
am Unable to get other IRPs like IRP_MJ_INTERNAL_DEVICE_CONTROL or
IRP_MJ_DEVICE_CONTROL in my upper filter driver. When I have made it
lower filter driver then I am able to get all IRPs. As according to my
understanding IRPs from IoManager should come to upper filter driver
first and then to the functional driver and then to lower filter
driver. Is there any special method to get all IRPs going to
functional driver in upper filter driver.

Thanks in Advance..

Eris
