    - NDISPROT sample performance (once again) Hello, Once again problem with NDISPROT sample from DDK. I've just built that example and did some tests. I've only increased a SEND_PACKET_POOL_SIZE RECV_PACKET_POOL_SIZE and MAX_RECV_QUEUE_SIZE values so that I have no more problems with loosing packets when reading. The big problem is performance I got with 9k frames average speed 350 MBps (sustained write and read) but maximum about 650 Mbps. Why that values are so different and how to improve the code to get better performance, more close to 1 Gbps. I have to get all the packet I do not want to discard any of them.

    - WIA Driver Development I am currently developing a WIA driver for my video camera/webcam device. What I planned to do is to create a WIA driver for my device so that whenever I connect the device to the pc, two camera devices will be automatically mounted on My Computer. One is the normal WIA camera device, which I can download the picture from camera. Another device is a video camera, which I can straightaway view the live video stream inside the device window without using any other application. Now, my question is how can I achieved it? which samples should i refer to? this is because i can't find any related sample inside the winddk. Thanks Tag: install driver package problem for DIFxAPI Tag: 79683

    - RtlCopyMemory problem hi all I used "allocateCommonBuffer" function to assign the memory allocation for DMA transmission. At the meantime, the data transferred from AP through "DeciveioCotrol" function are copied using "RtlCopyMemory" function, and then both data are compared using "RtlCompareMemory", there are some difference between the two in some circumstances. Why is that so? The code is as follow: case IOCTL_SEND_DATA: pMPG = (PMPG_PARAM) pIrp->AssociatedIrp.SystemBuffer; pOutBuf = (PULONG) pLDI->DMABuffers[0].Virtual;<--form allocateCommonBuffer RtlCopyMemory(pOutBuf, pMPG->pMessage, pMPG->nDataLen); DbgTrace(("Cnt: %d \n",RtlCompareMemory( pOutBuf,pMPG->pMessage,pMPG->nDataLen))); break; The struct of MPG_PARA is typedef struct _MPG_PARAM { ULONG nDataLen; ULONG pMessage[1]; } MPG_PARAM ,*PMPG_PARAM; Thanks a lot Tag: install driver package problem for DIFxAPI Tag: 79681

    - IOCTL_USB_GET_NODE_CONNECTION_INFORMATION not working on win2k+OHC Dear Sir, For detecting over-current condition on USB External hub ports, I'm using DeviceIOControl IOCTL_USB_GET_NODE_CONNECTION_INFORMATION (from NTDDK\usbioctl.h). This IOCTL returns a called USB_NODE_CONNECTION_INFORMATION, having an element USB_CONNECTION_STATUS. This is an enum. One thing it reports is DeviceCausedOvercurrent & DeviceNotEnoughPower values. I'm creating over-current condition on USB hub by connecting multiple devices (around 20) on 3 levels of hub. When I connect this setup to a server having EHCI controller & Win2k SP4 installed, this IOCTL correctly reports that at certains ports of the USB hub, value of USB_CONECTION_STATUS is DeviceCausedOvercurrent. But, when I connect this same setup to a server having chipset with OHCI controller & Win2k SP4, the same IOCTL gives USB_CONECTION_STATUS of NoDeviceConnected. Why is it that on Win2k3 with OHCI controller, the IOCTL reports correct status of the port, but on Win2kSP4 with OHCI controller, it is not giving correct results? Is this the known fact? Is this with OHCI controller's driver on Win2k SP4? How to work around this problem and get the correct status of the port? Please guide me.

    - NDISPROT read and speed problems. Hi all, I have to develop an 1 Gbps connection between our front-end board and PC. I found that the easiest and fastest way (especially form board development point of view) will be to use the raw Ethernet frames. I found that NDISPROT example from DDK could almost directly be used to send and receive raw frames. I've made some tests - just connect two PC with onboard gigabit NICs - and got problems. First is that the speed of the connection is about 350 Mbps and 150 Mbps for 9k frames and 1.5k frames respectively, which is event not close to 1 Gbps. Is that problem because of the NDISPROT driver itself or the NICs (NVIDIA nForce + Intel PRO 1000 MT) are not good enough? Second problem is when I sending frames from the first NIC and receive on the second no all frames are read out. Now I solve that problem just sending another small confirmation frame back, but it is no the way which I like. I have to mentioned that if on the receiver side I look to "Local Area Connection Status" the number of received frames is ok, so all have reached the receiver PC even without that confirmation frames.

    - IoGetDeviceObjectPointer and WdfRequestGetFileObject I am currently converting my WDM+DriverWorks drivers to KMDF. I have two drivers. The master driver(DeviceA) uses WDM+DriverWorks. The slave (DeviceB) has been converted to KMDF. DeviceA uses KLowerDevice (which embedds an IoGetDeviceObjectPointer call) to establish the connection between DeviceA and DeviceB. IoGetDeviceObjectPointer succeeds. DeviceA then builds a IRP_MJ_DEVICE_CONTROL itp to communicate with DeviceB. DeviceB receives the control code but WdfRequestGetFileObject returns NULL. If I use an user application to send the same control code to DeviceB, WdfRequestGetFileObject returns a valid WDFILEOBJECT. According to the KMDF documentation, WdfRequestGetFileObject will fail if a) Your driver has not called WdfDeviceInitSetFileObjectConfig and specified a WDF_FILEOBJECT_CLASS value that causes the framework to create file objects. >> I do call WdfDeviceInitSetFileObjectConfig in my EvtDriverDeviceAdd callback and the call does not fail when the user application runs. b) Another driver sent a read, write, or I/O control request to your driver without first sending a request type of WdfRequestTypeCreate. >> I have a trace statement in EvtDeviceFileCreate and the event is firing so DeviceA is sending the WdfRequestTypeCreate.

    - Printer Spool File Name In earlier versions of Windows, a printer spool name was in the form of XXXXX.SPL. Print Data being saved in directory \windows\system32\spool\printers. XXXXX were 5 decimal digits, equal to the jobid found in structure JOB_INFO_2. In my last version of Window XP-sp2, file names are now in the form FPXXXXX.SPL and the XXXXX value does not match any more with the "JobId". Strangely enough, if for a specific printer "Advanced Properties", function "Keep printed documents" is activated, the structure of printer spool name is back to the older version (5 decimal digits = JobId). Could somebody be so kind to tell me how to predict the Printer Spool File Name, for a specific "JobId". Many thanks. Tag: install driver package problem for DIFxAPI Tag: 79622

    - Easilly replace a Device Drive? I was asked to: 1. Verify if the correct Device Driver is installed. 2. If not - replace said driver by another one. My clientâ??s product is recognized as a â??Standard Deviceâ?? and Windows install a default driver not working with the product. The user must install the software first, but of course many do not read the manual ;) The product is done, ready to deliver, so the solution needs to be somewhat of a patch. I have never done such low level development (mainly end-user applications, GUI, and interfaces for DB) so I am not sure where to start; I am trying to avoid the DDK, I am hopping for a quick solution with a simple verification in the registry, and call some Windows API update/install functions. Does it make sense? Do I absolutely need the DDK? Where do I start? (A few functions of the API usually gets me started) Anyone can give me direction?

    - USBD behavior on surprise removal HI, MYusb function driver starts an i/o operation only after the earler one has completed i.e. the USBD has only one IRP pending at any time. Do I need to support IRP cancellation for this scenario. What I would like to know what happens if the user yanks out the usb device while the IRP is being procesed by the bus driver. The active IRP gets completed with an error status or the IRP remains pending. Does my device object get deleted? I guess no because it still has one reference to it? What happns if the user yanks out the device and puts it back again in a matter of few seconds. What I sometimes see that I now have two device objects which is something I don't want as I support only one device at a time. What should I do to avoid have two device objects. Does cancelling IRPs when surprise removal happens helps to solve this problem. Please guide me to any KB article on the behavior of USBD upon surprise removal and and an IRP active at the same time. I tried to find an exact answer but couldn't get it in DDK. Regds. Nitin Tag: install driver package problem for DIFxAPI Tag: 79598

    - Forcing spool files to contain EMF Hi again, After reading some material on printers, and asking questions in forums, I am still confused. So I thought I might try to rephrase my question and get a better answer. My final goal - Get an EMF from EVERY print that is issued (on every printer installed and from every application), analyze it, and stop or resume the print. I know EMF is undocumented, but these are my requirements so I want to stick to it in the meantime. My idea was to somehow make sure all spool files will contain EMF and not text or RAW. (And extract the EMF from the spool file) If I'll send all prints through a dummy printer driver (maybe I'll change in the registry and put my printer driver for all installed printers) which is local and always uses "Advance printing features" (set from the code) I should accomplish this? Is there another possibility? After I analyze the EMF, if I decide so, I can resend the spool file to a real printer to be printed. (Using OpenPrinter and WritePrinter). Again, this solution has to work on both local and network printer (eventually, I need the EMF on my system not on a remote one) Thanks. Tag: install driver package problem for DIFxAPI Tag: 79594

    - KS filter driver fails remove data format Hi, I am trying to build a video capture filter driver upon on webcam WDM driver. I need to remove some format such as MJPEG for post image processing. Now I encountered a problem. >From the MSDN of KS Data Formats and Data Ranges, KS filter reports all dataformat information thru KSPROPERTY_PIN_DATARANGES and KSPROPERTY_PIN_CONSTRAINEDDATARANGES. And clients use KSPROPERTY_PIN_PROPOSEDATAFORMAT and KSPROPERTY_PIN_DATAINTERSECTION to quest the format supportted status.

But after that, amcap can not preview, it reports "Error 80004002: Cannot find VCapture:IAMStreamConfig", followed with "This graph cannot preview" message.

    - RDR bug? The scenario: 1) Two different CDs with different \autorun.inf on them. In other words, the file names are the same, the content differ. 2) Two PCs in a LAN, the server and client 3) The CD drive on the server is shared; it's just a normal share with default settings. 4) Insert CD1 on the server. 5) Open and read \\Share\CD\autorun.inf on the client. All is OK. 6) Eject CD1, insert CD2. 7) Open and read \\Share\CD\autorun.inf. Now either CreateFile() fails with Win32 error 34 (ERROR_WRONG _DISK), or ReadFile() returns the old content from CD1. I can open all other files just fine, but not the files with the same name which were opened previously. Say, if I have \setup.exe on both CD1 and CD2, but I didn't open setup.exe at step 5, I can access CD2's setup.exe on step 7. How can flush the RDR cache on the client programmatically, instead of having to reboot the server or recreate the share every time? Thanks. A.

    - Listening to broadcasts for a port using TDI Hi, I'm attempting to write a function for a kernel driver of ours that will listen for a UDP broadcast on a specified port. I'm attempting to communicate with a device on the network that when given a directed UDP packet on a specified port unfortunately responds with a UDP broadcast to a different port. I tried to do an IoCallDriver call with an IRP created with TdiBuildQueryInformation and a QType of TDI_QUERY_BROADCAST_ADDRESS to obtain the broadcast address of the local-node. I get a status of STATUS_CANCELLED returned. I have many functions in our kernel drive that can communicate via UDP and TCP successfully, but I can't seem to create a connection to the local broadcast address. These functions work with abstract "Sockets". I know there are no sockets like in WinSock2 in the kernel space, but our functions use this concept via the IoGetDeviceObjectPointer call, etc., etc.. So I have a function that will successfully create a "Socket" and with this "Socket" I try to: 1. Find the local-node broadcast address via TdiBuildQueryInformation. (Unsuccessfully.) 2. Attempt to bind to 0xFFFFFFFF and setup a TDI_EVENT_RECEIVE_DATAGRAM event handler. I see the broadcast using Etherpeek, but the event handler is never fired. So I know that the code I have that creates a "Socket" works because I use it all over the driver code and it works. However, I'm not sure if I have to create the "Socket" a little different because I want to use it to accept broadcasts. I know that in WinSock2 you have to open the socket and prime, or set the broadcast option, to use broadcasts. It would seem logical that there was some sort of priming needed in the kernel space using TDI also. Any help on this subject would be much appreciated.

With the code, given below, I am able to get I2COpen & I2CAccess function pointers from Video Adapter.(that supports I2C Interface) But calling I2COpen function always fails and returns 0xC00000C2 error code. It is defined in ntstatus.h as #define STATUS_ADAPTER_HARDWARE_ERROR ((NTSTATUS)0xC00000C2L) There is no documentation available for this. Does anyone have any information about the sequence of calls to be issued to access the I2C Interface? Any help is appreciated. I'm calling LockI2Cprovider function after LocateAttachI2CProvider function call. The program fails in LockI2Cprovider () function. BOOLEAN LocateAttachI2CProvider( PDEVICE_OBJECT pVideoDeviceObject, PI2C_CONTEXT pstI2CContext ) { PIRP pIrp; BOOLEAN bResult = FALSE; PIO_STACK_LOCATION pNextStack; NTSTATUS ntStatus; KEVENT Event; I2CINTERFACE* pI2CInterface; if (pVideoDeviceObject == NULL || pstI2CContext == NULL) { return FALSE; } pI2CInterface = pstI2CContext->m_i2cProviderInterface; if (pI2CInterface == NULL) { return FALSE; } pIrp = IoAllocateIrp (pVideoDeviceObject->StackSize, FALSE); if( pIrp == NULL) { return FALSE; } pNextStack = IoGetNextIrpStackLocation (pIrp); // original if (pNextStack == NULL) { return FALSE; } pIrp->IoStatus.Status = STATUS_NOT_SUPPORTED; pNextStack->MajorFunction = (UCHAR)IRP_MJ_PNP; pNextStack->MinorFunction = IRP_MN_QUERY_INTERFACE; KeInitializeEvent( &Event, NotificationEvent, FALSE); IoSetCompletionRoutine ( pIrp, I2CScriptIoSynchCompletionRoutine, &Event, TRUE, TRUE, TRUE); pNextStack->Parameters.QueryInterface.InterfaceType = (struct _GUID *) &GUID_I2C_INTERFACE; pNextStack->Parameters.QueryInterface.Size = sizeof( I2CINTERFACE); pNextStack->Parameters.QueryInterface.Version = 1; pNextStack->Parameters.QueryInterface.Interface = (PINTERFACE) pI2CInterface; pNextStack->Parameters.QueryInterface.InterfaceSpecificData = NULL; ntStatus = IoCallDriver (pVideoDeviceObject, pIrp); if( ntStatus == STATUS_PENDING) { KeWaitForSingleObject( &Event, Suspended, KernelMode, FALSE, NULL); } if ((pI2CInterface->i2cOpen == NULL) || (pI2CInterface->i2cAccess == NULL)) { return FALSE; } else { DebugPrint ("deviceInfo->m_i2cProviderInterface->i2cOpen 0x%x", pI2CInterface->i2cOpen); DebugPrint ("deviceInfo->m_i2cProviderInterface->i2cAccess 0x%x", pI2CInterface->i2cAccess); } pstI2CContext->m_pdoDriver= pVideoDeviceObject; bResult = TRUE; if( pIrp != NULL) IoFreeIrp( pIrp); return bResult; } BOOLEAN LockI2CProvider (PI2C_CONTEXT pstContext) { NTSTATUS status; if ((pstContext->m_i2cProviderInterface->i2cOpen == NULL) || (pstContext->m_i2cProviderInterface->i2cAccess == NULL) || (pstContext->m_pdoDriver == NULL)) { return FALSE; } pstContext->i2cAccessBlock->Status = I2C_STATUS_NOERROR; status = pstContext->m_i2cProviderInterface->i2cOpen ( pstContext->m_pdoDriver, TRUE, pstContext->i2cAccessBlock); if (status != STATUS_SUCCESS) { DebugPrint ( "CI2CScript: LockI2CProvider() status = 0x%lx\n", status); return FALSE; } pstContext->m_dwI2CAccessKey = pstContext->i2cAccessBlock->dwCookie; DebugPrint ("LockI2CProvider m_dwI2CAccessKey %ld", pstContext->i2cAccessBlock->dwCookie); return TRUE; } Thanks VK Tag: install driver package problem for DIFxAPI Tag: 79538

    - Win98 Smartcard Reader Hot plug-in problem My Win98 USB Reader driver works well if USB reader plugged before Win98 boot. But if I plugged reader after Win98 boot, seems pc/sc manager couldn't talk to driver correctly. From driver debug, I found all driver PnP enumerate IRP worked well, but driver couldn't get smartcard service request. I wonder if pc/sc manager support USB reader hot plug-in in Win98?

But if I run DDK tool dc2.exe in command line for my driver, like: dc2 /hct /dr drivername. It PASSED. What's the different between these two kinds of tests?? When I got BS, how to use the dump file ? I have tried to open dump file in windbg, it returned"symbol not found", I have added pdb file into the "symbol path". Any more setting I need ?

    - How to send a simple MIDI-note on a soundcard? I am a newbie in kernel-streaming topics and the drivers... All I need is to play a midi-note in windows kernel-mode. Like MidiOutShortMessage in WinAPI. Where can I read the manuals or examles? Must I use IMiniport interfaces or create complex streams? But how to use this IMiniport interfaces I don't understand completely. All I understand now is to find some PortMidi in system, create a new stream in his Mimiport and to write data. But I don't knpw how to find this Port. I think, there is no need in creating new port. Can you give me code-examples or even ready code? It is easier to understand topics with examples. I must implement this in coming days, it is my home task in university. -- Avtoritet ------------------------------------------------------------------------ Posted via http://www.codecomments.com ------------------------------------------------------------------------ Tag: install driver package problem for DIFxAPI Tag: 79517

    - How to send USB Set_Idle request to HID driver? I have a USB mouse device that repeatedly sends reports even when nothing has changed. I need to issue a USB Set_Idle request to tell it to only report changes. This mouse uses the built-in HID class driver that's part of Windows. Can this be done from a user-mode app? I looked at al the HidD_Xyz functions, but didn't see anything. If this can only be done from a driver, how would I go about getting a reference to the standard HID class driver associated with this device so I can send it a USB URB? I tried using IoGetDeviceInterfaces( &GUID_DEVINTERFACE_HID ) and calling IoGetDeviceObjectPointer on every device it found, but it failed with every device.

    - Why doesn't mirror driver catch BitBlt sometimes? my mirror driver can catch BitBlt call. But I noticed that it's failed to catch BitBlt sometimes immediately after I change the screen resolution. I want the mirror driver be able to capture the whole screen at first by using BitBlt(hdc2,0,0,SCREEN_WIDTH,SCREEN_HEIGHT,hdc1,0,0,SRCCOPY)). I found that BitBlt was executed successfully, But mirror driver didn't capture it. why? BTW, if I right click the task bar and select show the Desktop, the mirror driver may capture the whole screen always. Does anyone help me out? any comment?

    - WMI Property Page for Driver I have added WMI support for the driver and I can access the class and the properties using wbemtest and other utlilities. However, there is something that the DDK mentions about having a Property Page and I am not able to see where the propety page comes or how to enable the property page ? I have browed theough the device manager, services menu et al but I cant find it. this is what the DDK says... "Drivers can automatically expose any WMI classes they implement on their property sheet by using the WMI generic property page provider." I have enabled everything through the INF that the DDK says about the property page provider and the co-installer as below, but I still can't find the damn property page..neither in the device manger( by right clicking the device or elsewhere). Any help is appreciated. Thanks. This is from the DDK and I am doing everything as below. Enabling the Generic Property Page Provider To use the WMI generic property page provider with your driver, you must enable wmiprop.dll as a device co-installer. In the CoInstaller add-registry-section, register wmiprop.dll as a co-installer for the WMI class by adding a value entry for the class GUID under the HKLM\System\CurrentControlSet\Control\CoDeviceInstallers key. The value for the value entry is "WmiProp.dll, WmiPropCoInstaller". For example: ; This section is defined in the CoInstaller section, as follows. ; [CoInstaller] ; AddReg = CoInstaller_AddReg [CoInstaller_AddReg] HKLM, System\CurrentControlSet\Control\CoDeviceInstallers, ClassGUID, 0x00010000, "WmiProp.dll, WmiPropCoInstaller" ClassGUID is the GUID for the WMI class. See Registering a Class Co-installer for details. You must also specify the particular WMI classes to be exposed through the generic property provider. To do this, set the WmiConfigClasses value-entry to be a comma-separated list of the WMI classes in the add-registry-section of the device class or device hardware instance. ; the device class AddReg section. [device_class_AddReg] HKR,,"WmiConfigClasses",0x00000000,"class1,class2" ; the device hardware instance AddReg section. [device_hw_inst_AddReg] HKR,,"WmiConfigClasses",0x00000000,"class3" Tag: install driver package problem for DIFxAPI Tag: 79511

    - Driver project configuration. Hi all, I'm interested in developing Win32 device drivers using the Visual Studio .NET 2003 IDE. (I'm purposely trying to avoid using DDK make files for internal maintenance reasons - trust me, they warrant this action.) Since I'm developing the drivers from scratch I thought I should be able to do this without problems. I've read a few articles about device driver development and have successfully implemented an example driver using the IDE by manually specifying the necessary compiler switches, but I'm not sure how to make certain features work. For example, if I enable C++ exception handling, I receive the following link error: Defs.obj : error LNK2019: unresolved external symbol __CxxThrowException@8 referenced in function "void * __cdecl operator new(unsigned int,enum EMemPool)" (??2@YAPAXIW4EMemPool@@@Z) I discovered that if I manually link in the "libcmt.lib" library then the symbol is resolved, but this is no good because it results in the following link errors (as I expected): kernel32.lib(KERNEL32.dll) : warning LNK4237: /SUBSYSTEM:NATIVE specified when importing from 'KERNEL32.DLL'; Use /SUBSYSTEM:CONSOLE or /SUBSYSTEM:WINDOWS. LINK : warning LNK4078: multiple '.rdata' sections found with different attributes (C0000040) My project is obviously implemented in C++. Now, I know just about every driver developer out there is thinking that one should never use C++ in drivers, but I have yet to discover any compelling reason why, so unless you've got one, please don't respond to this post only to bark at me about how C++ is evil (or whatever.) Please understand that when you respond to the post others that have the answers I need won't because they will assume I have received the information I need. I've overridden the global new and delete operators so I can control whether memory is allocated from the paged or non-paged pool and I've carefully selected my compiler switches to insure that all necessary sections exist and have the proper attributes. At this time it seems that the only problem I have is that I'm missing the VC++ exception handling routines that live the CRT libraries. So I either have to not use exceptions, which is a major loss to me, or find out how to resolve these symbols. Can anyone point me in the right direction? I'm also not sure what I'll be loosing by opting not to use the DDK build system (make files) and using the VS.NET 2003 IDE instead. Is there anything or do the make files primarily just configure build switches, etc? Thanks in advance, Matt Tag: install driver package problem for DIFxAPI Tag: 79501

    - Mount manager and virtual disk drive Hello, I devloped a virtual disk driver based on the ramdisk sample several years ago. Now we found out, that I can't share the drives on the network or defrag it. Every time I try create a share name I get an error like "device or directory dosen't exist". I guess that IoRegisterDeviceInterface () may solve my problem, but I don't have a PDO... Can swenum supply me a "virtual PDO" ? Is there anywhere a sample for swenum?

I encountered a problem for DIFx Tool in WinOS XP. The step is as follow:

1.Plug in the Card.

2.Install Driver Package by using DIFxAPI.
=> Install successfully.

=>Don't unplug the Card.
3.Uninstall Driver Package by using DIFxAPI.
=> Uninstall successfully.

=>Don't unplug the Card.
4.ReEnumerate Device.
=>To ReEnumerate the device is fail.

5.Install Driver Package by using DIFxAPI.
=>Install fail.

Some computer can occur the situation, and others can't.

If I can't use DIFxAPI, I use DDK API to remove device. The result is that
it can reenumerate the device.

Please give me some suggestions. Thank you.
