    - usbccid driver : enable Escape command Hello, I use the usbccid driver to develop a smartcard application. As explained in the usbccid driver documentation : http://www.microsoft.com/whdc/device/input/smartcard/USB_CCID.mspx "In order to send or receive an Escape command to a reader, the DWORD registry value EscapeCommandEnable must be added and set to a non-zero value under the HKLM\SYSTEM\CCS\Enum\USB\Vid*Pid*\*\Device Properties key." My problem is to find a way to automaticaly add the EscapeCommandEnable DWORD in HKLM\SYSTEM\CCS\Enum\USB\Vid*Pid*\*\Device Properties during the installation of the application. (it is only during the installation of the application that you have the administrator rights and so you can add a value in the registry base). - Is there a version of the usbccid driver available that avoids to modify the registry (with Escape command always enabled) ? - if I modify the usbccid.inf file so that this DWORD will be add in the registry base : unfortunately the driver will not be signed anymore which is too bad. - The path depends on the USB port where the reader is plugged : which means that the administrator will have to plug the reader to all USB ports during the installation process to add each value to the right registry path and so to be sure that he will be able to use the reader with all its computer ports . I hope someone has a solution. Have a nice day Olivier Tag: Sending network data from driver mode Tag: 62427

    - Which tools do I need exactly to write a device driver? Hi, I'm new to device drivers. Which tools do I need exactly to write a device driver? Is installing the DDK sufficient or do I have to use some other MS compilers in addition to the compiler which comes with the DDK? If this is the case, there are Visual Studio .NET 2003 Enterprise Architect, Visual Studio .NET 2003 Enterprise Developer, Visual Studio .NET 2003 Professional Special Edition, Visual C++ .NET 2003 Standard. which one can I use? (I prefer using Visual C++ .NET 2003 Standard because it's the cheapest) Thanks in advance. Tag: Sending network data from driver mode Tag: 62423

    - How to prevent context switching? Hi, I am bit new to driver programming. I would like to know how to prevent context switching between threads. Here is the scenario: Thread A is running at PASSIVE LEVEL, driver gets into some funny state and hence I want to panic the system so that I can get a memory dump to diaognise the problem. So before crashing, I copy required data in a temporary buffer. When I am about to panic the system, another thread B gets scheduled, pre-empts the already running thread A, does context switching and runs for a short burst and clear the data from my main buffer. Once thread B finshes, thread A resumes the operation and panics the system. When I analyze memory dump, I notice that contents in temp buffer and main buffer differ because of context switching. I want to know how do I prevent this context switching between threads A and B? As soon as I get into funny state, I want to copy the data in temporary buffer and crash the system. Thanks.

    - Simple Application Hello, I am trying to write a simple application that will look at a hardware address lets say &HA400 or &H378 approximately 1000 times per second. Every 100th time though I need to write out the value to the registry (any place will work). Is a device driver appropriate for this kind of application? If not, can someone point me to the right newsgroup? If so, does anyone have any examples or port IO or registry writing?

    - Override kernel exception handler? In postin http://msdn.microsoft.com/newsgroups/managed/default.aspx?dg=microsoft.public.development.device.drivers&mid=74822b53-9342-4101-bbb8-b0daf2afc25b&sloc=en-us I learned that __try/__except and such can only catch a subset of all exceptions that may occur in a kernel driver. Unless we write perfect code, this will eventually come back and bite us. Is it at all possible - probably not advisable though - to override the kernel exception handler? I'd write some exception information to the disk, then reboot. Unless there is a supported way of replacing the default exception handler, would I gain anything by replacing KeBugCheck or KeTrap in memory, by a call/jump to my own exception handler? I realize this may seem far-fetched... Any input appreciated, / Hannes. Tag: Sending network data from driver mode Tag: 62391

    - How to acess EFI system table Am intrested in writing wdm driver for pci express.. i require to acess RSDP structure.. Are there any Api's to check whether the system is EFI enabled or not ? Or w'd i understand whether the system is EFI enabled or not?? In Extensible Firmware Interface (EFI) enabled systems (for example, ItaniumTM-based platforms) a pointer to the RSDP structure exists within the EFI System Table. The OS loaderâ??s EFI image is provided a pointer to the EFI System Table at invocation. The OS loader must retrieve the pointer to the RSDP structure from the EFI System table and convey the pointer to OSPM, using an OS dependent data structure, as part of the hand off of control from the OS loader to the OS. The OS loader locates the pointer to the RSDP structure by examining the EFI configuration table within the EFI system table. Any suggestion about EFI & windows driver is appreciated.. -- Vijay PIC ,Bangalore Tag: Sending network data from driver mode Tag: 62382

    - Debugging Help Hi, I am trying to debug a NDIS Miniport driver. I have setup both Target and Host machines connected through NULL modem. I have tested null moded using Hyper Terminal. On the Host machine I am running WinDbg with Kernet Debugging on and it gives the message "Waiting for connection ........". On the Target machine I have changed the boot.ini to include my port settings. Now the problem is that most of the time it does not work. Nothing is displayed on the WinDbg command window on Host machine. But sometimes it do work and I can see the output. I tied rebooting the Target machine, but nothing happens. Sometimes when I press CTRL+C on the Host machine, my Target machine hangs. Any ideas, why this random behaviour is happening???? JS Tag: Sending network data from driver mode Tag: 62381

    - Getting display information through DDC Can anyone here point me to some examples (preferrable including code) of how to retrieve display information through DDC? Since DDC calls happen in RTM, they are not supposed to be allowed in Windows protected mode as I understand it. People say, it is necessary to create a driver for this. I would need an example of how to do this, since I am not exactly a driver expert ;-) Any help would be much appreciated! Best Regards, Christian.

    - scsi miniport dma data corruption Dear all, I have PCI controller that has DMA channel 0/1 for data transmission, the flow of dma command issued by scsi miniport was just set DMA control register, everything is ok, but sometimes the buffer content of scsi miniport read from PCI memory was not the expected data, it may lost 1 or 2 word byte, I have tried PCI controller function in real mode (DOS), and the result was as expected. After rescan DDK document, I found that DMA cache or cachebuffer may cause this problem. Can somebody tell me that direction was right or this situation comes from other source?

    - ZwCreateFile question I know that files I'm interested in are open for write access of some sort. I'd like to open those files but merely for read access prior to a write, so I open it like so: InitializeObjectAttributes(&ObjAttrs,InFile,OBJ_KERNEL_HANDLE|OBJ_CASE_INSENSITIVE,NULL,NULL); // Status = ZwCreateFile(&FileHandle, GENERIC_READ|FILE_READ_ATTRIBUTES|FILE_READ_DATA, &ObjAttrs, &StatusBlock, 0, //allocation size FILE_ATTRIBUTE_NORMAL, FILE_SHARE_READ|FILE_SHARE_DELETE, //share access FILE_OPEN, // disposition FILE_NON_DIRECTORY_FILE|FILE_SYNCHRONOUS_IO_NONALERT,//CreateOptions, 0, // EaBuffer OPTIONAL, 0 ); Yet, I'm getting : STATUS_SHARING_VIOLATION ((NTSTATUS)0xC0000043L) errors. Must I open the file with precisely the same ACCESS_MASK as was originally used? On the other hand, I do have the FileObject for this guy based on it being open for Write. Can I get a handle for reading with ObOpenObjectByPointer? -- Gak - Finecats Tag: Sending network data from driver mode Tag: 62351

    - USB 2.0 High speed Isochronous Hi, I'm deveoping a driver using USBCAMD2 for an FX2 Cypress device. In USB 2.0 Isochronous High-Speed mode I transfer a stream about at 7.8 MB/s. This is correct if you set 1024 byte per Microframe with 125us interval. My problem is that I want to transfer 3*1024 bytes every Microframe with 125us interval to reach about 23 MB/s. I know this is theoretically possible with USB 2.0, but I don't know how to program my driver to increase transfer rate. My Endpoint descriptor is : bmAttributes = 0x01 (Isochronous) wMaxPacketSize = 0x1400 (3*1024) bInterval = 0x01 (125 us) How can I transfer about 23MB/s with USB in Isochronous mode ?

Return value 3. The driver is signed. If I use chktrust on the .cat file it reports that it is properly signed. Is there any other utility that would be more appropriate to use? My only clue here is that maybe there is a file that is not included in the signature that should be, or there is a file that is included that shouldn't be. How can I determine the problem? My driver consists of a single .sys file. I also include a stripped .pdb file. That means my .cdf file that creates the .cat file looks like: [CatalogHeader] name=driver.cat [CatalogFiles] driversys=driver.sys driverinf=driver.inf driverpdb=driver.pdb I then sign the .cat file. The .inf file has an entry that points to the cat file: [Version] Signature = "$Windows NT$" Class = "Replication" Provider = %Company% DriverVer = 01/01/05,0.0.0.0 CatalogFile = driver.cat DriverPackageType=FileSystemMinifilter DriverPackageDisplayName=%DriverServiceDesc% Any help or any idea on what to look for would be greatly appreciated! This worked in DIFxApp 1.1!!! Thanks! Bob Tag: Sending network data from driver mode Tag: 62347

    - Shell Namespace vs. Device Driver Hi, A short time ago, I asked a question in this newsgroup about writing a device driver. It is: -- Hi, I would like to write a program: In Windows Explorer, after drag&drop a file to a pre-defined drive letter (for example F:) the file should be sent through the COM port to an external device(digital satellite receiver). Where should I start? Do I have to write a device driver? -- I was told that writing a device driver is not neccessary and a Shell Namespace Extension with a drag&drop handler can do the job. I had a short look at MSDN about Creating a Shell Namespace Extension. Now, I'm asking my question more clearly. My scenario is: As soon as the user attaches the RS-232 cable to the computer (at the other end it is attached to the RS-232 port present on the external device) a drive letter F: should appear in Windows Explorer automaticly(like in digital cameras) and when the user drag&drops a file to F: the file should be sent through the COM port to the external device. So, can Shell Namespace Extension provide what I need? I'm going to execute my program with Shell Namespace Extension only once, then restart the computer. Now, may I expect to see the drive letter F: in Windows Explorer if I attach the RS-232 cable to the computer? Will it disappear if I detach the cable? About the other case (displaying the drive letter F: automaticly is not necessary, it may always be visible, it will not be influenced from attaching and detaching the cable): I'll execute my program with Shell Namespace Extension. I'll see the drive letter F: in Windows Explorer, then I can transfer the file to the external device. What will happen if I restart the computer? Will the drive letter F: remain in Windows Explorer? Thanks... Tag: Sending network data from driver mode Tag: 62344

    - problem with NdisReturnPackets ( ) Hello, All! I get BSOD on vmware 5.0 and some other networc cards. It does not happen on other vmware versions and physical NICs. The problem appears when I try to send previously queued packed. The same(?) packets are sent before BSOD using the same functions, pools, etc without problems. On Windows 2000 Pro, mydriver rises D2 bugcheck somewhere in ethFilterDprIndicateReceivePacket (instead of D1 one in XPsp2 system, see below). Does anybody know why this may happen? According to http://pcausa.com/support/KB05050101.htm I use separate pools for send and receive packets. Also, I tried to zero Packet->MacReserved field. No luck.

    - SetPort (printer driver language monitor) Hi all, I wish the SDK explained the SetPort function better. I'm not really sure what it does other than change the "Status" messages column in the "Printers and Faxes" dialog box. Does it do anything else? I've discovered if I use PORT_STATUS_TYPE_ERROR for dwSeverity that it does seem to hang up the spooler, and I can't seem to clear it later. Thats ok, because I found that PORT_STATUS_TYPE_WARNING is ok for my use. My real question is that I would like to use the pszStatus member of PORT_INFO_3 to display my own messages up there, but it doesn't seem to do anything. The SDK says that if the predefined messages available for dwStatus aren't enough that you can define your own with pszStatus. So, this is what I do: PORT_INFO_3 pi3; pi3.dwStatus = 0; // set to zero because none of these messages apply. pi3.pszStatus = TEXT("My Printer Message"); pi3.dwSeverity = PORT_STATUS_TYPE_WARNING; SetPort(NULL,pPortName,3,LPBYTE(&pi3)); Does anybody have any ideas? Thanks! Tag: Sending network data from driver mode Tag: 62328

    - try/except does not catch all exceptions...? I am trying to use __try/__except to catch crashes that may occur in my driver. It works great for NULL pointer access, but not for a plain bad memory access. If the driver accesses 0xfefefefe (just as a test!), I see a crash in WinDbg, instead of my exception handler getting launched. The crash is below. How do I catch it (and other exceptions) ? PAGE_FAULT_IN_NONPAGED_AREA (50) Invalid system memory was referenced. This cannot be protected by try-except, it must be protected by a Probe. Typically the address is just plain bad or it is pointing at freed memory. Arguments: Arg1: fefefefe, memory referenced. Arg2: 00000000, value 0 = read operation, 1 = write operation. Arg3: b94ca75d, If non-zero, the instruction address which referenced the bad memory address. Arg4: 00000000, (reserved) / Hannes. Tag: Sending network data from driver mode Tag: 62321

    - INF model section decoration 64-bit Windows2003 AMD64 Hi, I am trying to install 64bit printer driver thru. HW1st on beta version of 64-bit Windows2003 build 3790 v.1433 installed on AMD64 machine. Getting an error "can not Install hardware unable to detect device ID". In printer INF file, I have described the decorated model section for windows2003 in following way. [MANUFACTURER] %ABC%=Models,NTamd64.5.2 // Here 5 is MajorOSversion and 2 is MinorOSVersion [Models.NTamd64.5.2] I have also tried with following model section [Models.NTamd64] Still giving the same error "can not Install hardware" on 64-bit Windows2003. Same model decoration is working fine on 64-bit WindowsXP. When I turnoff the undecorated models check by setting registry variable DisableDecoratedModelsRequirement to 1 then 64-bit printer driver gets installed on 64-bit windows 2003. So, I think problem is with model decoratation for 64-bit windows2003. Can anyone tell me what should be the model decoration for 64-bit Windows2003. thanks in advance regards manoj Tag: Sending network data from driver mode Tag: 62315

    - Ndis - DHCP Hi All, I am making use of netvmini sample(Virtual miniport driver). I have modified the code in such a way that i can change the cable status using control codes which will trigger a NDIS_MEDIA_STATUS_CONNECT and NDIS_MEDIA_STATUS_DISCONNECT in driver. It is working fine. But sometimes though adapter is configured to use static IP, on receiving CONNECT control code which will trigger NDIS_MEDIA_STATUS_CONNECT, the status in the network connections window says "Acquiring network address" . The ip address displayed is 0.0.0.0 but soon after the status becomes connected and it chages back to static IP which i configured . What i observed is this happens with LAN as well as WLAN in my machine when they are configured with static IP. When i unplug and plug network cable of LAN adapter, the same event happens sometimes which results in erratic behavior of sockets. Could anyone let me know how can i fix this?Would be of great help if u could let me know what all are the events happens at "Acquiring network address".

    - Link between setup classes and interface classes. Dear All, I would like to communicate directly with USB and parallel local printers using CreateFile, WriteFile and ReadFile functions from the Windows API. To retrieve local printers connected to a PC, I used the setupapi with the printer setup class as follow : SetupDiGetClassDevs(&GUID_DEVCLASS_PRINTER, 0, 0, DIGCF_PRESENT); Then I could enumerate the printers using SetupDiEnumDeviceInfo (). To communicate with the printers using CreateFile, WriteFile and ReadFile functions, I figured out I had to retrieve the "symbolic name" of the printers using SetupDiGetDeviceInterfaceDetail (). How can I get the device interfaces of the printers I retrieved using SetupDiEnumDeviceInfo () ? What is the link between setup class and interface class ? Best regards, Guillaume.

    - Get service pack name from a driver? Hi, From within a driver, I want to get the string name of the service pack, e.g. "Service Pack 1, v.1247" The function PsGetVersion() is supposed to do the trick, but I can't get a string out of it, neither from within DriverEntry, nor any other point in my driver. (I do get other version info from PsGetVersion() though, but not the SP name.) Is there any other way to get the service pack name string from within a driver? Thanks, / Hannes.

    - Application can't be killed while on a synchronous read I wrote a driver that is not allowing a console application which is blocked on a synchronous ReadFile() to be killed (ctrl-C or taskmanager). Nor can I remove the driver with out rebooting the system. What am I doing wrong -- details below. I have created a pure software driver that reads and writes from an internal buffer. If data is available the read IRP it will complete immedately, else it will PEND. A Device I/O Control is used to indicate that data is available, and if a read IRP is pending will complete it. I have tested with a TestRead.exe that syncrhonously reads the device and a TestRelease program that writes and sends the IOCTL_RELEASE_READ. Things work fine with the test program interaction, immediately reading or blocking until data is availalbe. HOWEVER, when I run the TestRead and it blocks I can not Ctrl-C the program or use the TaskManager to kill the program. Why is this? I understood that the I/O Manager was support to clean all the synchronous calls/Reads and allow exit of the program, but this is not happening. What am I missing? Below are what I believe to be the critical pieces: NTSTATUS DispatchRead (IN PDEVICE_OBJECT pDevObj, IN PIRP pIrp) { NTSTATUS status = STATUS_SUCCESS; [ declarations ...] PDEVICE_EXTENSION pDevExt = (PDEVICE_EXTENSION) pDevObj->DeviceExtension; if (pDevExt->bDataReady) { [fill read buffer ...] // Now complete the IRP pIrp->IoStatus.Status = status; pIrp->IoStatus.Information = nBytes; // bytes xfered IoCompleteRequest( pIrp, IO_NO_INCREMENT ); return status; } else { pDevExt->pIrpPendingRead = pIrp; // save pointer to IRP status = STATUS_PENDING; IoMarkIrpPending(pIrp); pIrp->IoStatus.Status = status; pIrp->IoStatus.Information = 0; // bytes xfered return status; } } NTSTATUS DispatchIoControl(IN PDEVICE_OBJECT pDevObj, IN PIRP pIrp ) { PIO_STACK_LOCATION pIrpStack = IoGetCurrentIrpStackLocation( pIrp ); PDEVICE_EXTENSION pDevExt = (PDEVICE_EXTENSION) pDevObj->DeviceExtension; // Release read is send when data is available if (pIrpStack->Parameters.DeviceIoControl.IoControlCode == IOCTL_RELEASE_READ ) { if (pDevExt->pIrpPendingRead == NULL) { pDevExt->bDataReady = TRUE } else { // The stack location contains the user buffer info PIO_STACK_LOCATION pPendingIrpStack = IoGetCurrentIrpStackLocation( pDevExt->pIrpPendingRead ); [decls and read Irp buffer copy stuff ...] // Complete Pending Read IRP pDevExt->pIrpPendingRead->IoStatus.Information = nBytes; pDevExt->pIrpPendingRead->IoStatus.Status = STATUS_SUCCESS; IoCompleteRequest( pDevExt->pIrpPendingRead, IO_NO_INCREMENT ); pDevExt->pIrpPendingRead = NULL; // "remove from queue of one" } // Complete Device IO Irp pIrp->IoStatus.Information = pDevExt->bSetPendingRead; pIrp->IoStatus.Status = STATUS_SUCCESS; IoCompleteRequest( pIrp, IO_NO_INCREMENT ); return STATUS_SUCCESS; } else { [ not implemented completion of IRP ...] return status; } } Tag: Sending network data from driver mode Tag: 62284

    - question on USB pipe flags Hello. My device is USB composite (1.1), and the interface I am working on is for ASIO (audio) streaming. I have two questions for USB pipe flags: a) What do USBD_PF_ENABLE_RT_THREAD_ACCESS and USBD_PF_MAP_ADD_TRANSFERS actually do? The DDK says that the former is enables optimization for streaming transfers while the latter enables "fast isochronous mode". Can anyone shed light on what these actually do? b) Since I have a composite device, I use URB_FUNCTION_SELECT_INTERFACE instead of URB_FUNCTION_SELECT_CONFIGURATION to allocate bandwidth and receive my pipes. However, the DDK implies that the aforementioned flags (see above) work for URB_FUNCTION_SELECT_CONFIGURATION. Does this mean that they are inaccessible to me, as I am forced to use these flags in my URB_FUNCTION_SELECT_INTERFACE request? thanks, Philip Lukidis Tag: Sending network data from driver mode Tag: 62281

    - Audio Delay From Audio Capture Source Filter Dear All: I designed a AVstream driver with video and audio streams. Then, using the graphedit to play and capture it. The audio stream is offered from Audio Capture Source (qcap.dll). The video stream is offered from Video Capture Source filter's capture pin. However, the audio sound has a serious dealy (about 1 ~ 2 sec) to video in previewing. But, its captured avi file is AV-Sync well. This is my driver's bug? I had tried other video devices (USB2.0 Video Grabber). Their preview and capture are AV-Sync both. The USB device is a standard USB Audio Class device. It uses Microsoft's USBAUDIO.sys driver. Why cannot MS's driver cause the preview delay? Best Regards, H.P. Tag: Sending network data from driver mode Tag: 62277

    - How to use DbgPrompt in drivers? Dear All, Recently I read the article "Try This -- Interactive Driver Testing" (The NT Inside, Vol 11). It introduces a minimal driver skeleton. I tried to build the code, but encountered a compiler error. The code uses the function "DbgPrompt". But there is no declaration of DbgPrompt in any *.h files in Win DDK (2600). And there is no information about this function in DDK's help. I have noted that the function is exported by ntoskrnl.lib. So I added "TARGETLIBS=$(DDK_LIB_PATH)\ntoskrnl.lib" in "source" file. But I still need to know the declaration of the function "DbgPrompt". Can anyone tell me about this or how to use "DbgPrompt" in drivers. Thanks in advance.

    - STATUS_REPARSE across network share Hello Everybody, I have a filter driver that uses STATUS_REPARSE to redirect file opens in its IRP_MJ_CREATE routine as documented in this list and many other places (http://support.microsoft.com/default.aspx?scid=kb;en-us;319447). The actual files reside on a network share (e.g. reparsed to \device\mup\server\share). This technique works well for IO requests originating from the local system however if the request comes across the network (e.g. via SRV) it fails with 'access denied'. This is obviuosly becasue the access request is in the context of the system. My question is this: is it possible to make this work using impersonation or delegation, or do I need an etirely different approach to the problem? Thanks in advance for any help or advice, zengfeng.

    - Get temperature values from the cpu/motherboard How can I get temperature values from the CPU and motherboard of a machine? I've try querying WMI (using IWbem_ methods with win32_temperatureprobe), which hasn't worked - it says the temperature sensors don't exist. Is there some other way I can get this data? Note: project also requires getting CPU usage info, which I've already done through WMI, so a WMI solution to getting the temperature values is preferable, but not necessary. Thanks!

Hi,

I have a disk class filter driver. I need to send some data to another
machine through network. How I can do network operations from kernel
mode?

Please help me. Is there any sample code available ?

Thanks ,
Binoj

You can use the TDI interface. Also, there're kernel mode socket in the
market.
