    - Serial Out from Kernel Mode Hi All, I need to pass the debug statements from a kernel driver thru the serial port to a different machine. I have tried the following code: fileName.Buffer = NULL; fileName.Length = 0; fileName.MaximumLength = sizeof(DEFAULT_LOG_FILE_NAME) + sizeof(UNICODE_NULL); fileName.Buffer = (PWSTR)ExAllocatePool(PagedPool, fileName.MaximumLength); if (!fileName.Buffer) { //DD(NULL,DDE,"LogMessage: FAIL. ExAllocatePool Failed.\n"); KdPrint((DRIVERNAME " LogMessage: FAIL. ExAllocatePool Failed")); return FALSE; } RtlZeroMemory(fileName.Buffer, fileName.MaximumLength); status = RtlAppendUnicodeToString(&fileName, (PWSTR)DEFAULT_LOG_FILE_NAME); InitializeObjectAttributes (&objectAttributes, (PUNICODE_STRING)&fileName, OBJ_CASE_INSENSITIVE|OBJ_KERNEL_HANDLE, NULL, NULL ); status = ZwCreateFile( &FileHandle, //FILE_APPEND_DATA, FILE_WRITE_DATA, &objectAttributes, &IoStatus, 0, FILE_ATTRIBUTE_NORMAL, FILE_SHARE_WRITE, FILE_OPEN_IF, FILE_SYNCHRONOUS_IO_NONALERT, NULL, 0 ); ZwWriteFile( FileHandle, NULL, NULL, NULL, &IoStatus, buf, Length, NULL, NULL ); to do this... But More often than not I dont get the Serial out messages. At some times I do get a few Serial outs on the remote machine but there seems to be some baudrate problem. I Also tried this: PDEVICE_OBJECT SerialDevice; PFILE_OBJECT FileObject; UNICODE_STRING uszDevName; WCHAR szDevName[] = L"\\Device\\Serial0"; RtlInitUnicodeString (&uszDevName, szDevName); status = IoGetDeviceObjectPointer (&uszDevName, SYNCHRONIZE|GENERIC_READ|GENERIC_WRITE, &FileObject, &SerialDevice); if (!NT_SUCCESS(status)) { KdPrint((DRIVERNAME " IoGetDeviceObjectPointer:Error cant open File ")); return FALSE; } // if else { KdPrint((DRIVERNAME " Bingo Got it")); } But cant open handle this way. Can anyone suggest what is a best way to do this. Sunil. Tag: sony display driver Tag: 48807

So as I now understand, the answer to 2 is no and, hence, there is no bug. The confusion came from the apparent effort in PASSTHRU to guarantee no packets leave low-power edges. So, when I saw a violation of this, I assumed it was a bug. IMHO, a clarifying comment in the code would be helpful to future newcomers.

    - Notifications to a DLL I am new to driver development, so my question might be a bit naive. The Situation: I'm developing a USB-based device. A user can connect or disconnect one or more of these devices at any time. I provide a dll to interface between a Windows application and my kernel-mode driver (under construction). Either I or my customer customer will create his/her own Windows app, in their favorite programming environment. The Problem: I'd like to provide callback functions in my dll that will execute whenever a device is connected or disconnected. I can see that there is an SDK Platform function RegisterDeviceNotification that allows user code to register for a callback to a window or service. But I don't have either in my dll. This does not therefore seem to meet my needs. I also see that the IO Manager exports the IoRegisterPlugPlayNotification for drivers. It accepts a callback function argument. The Questions: Can I use the IoRegisterPlugPlayNotification function and locate the callback function be in my (user mode) dll? Or, is there a way to use the RegisterDeviceNotification user-mode function with my dll? Or, is there a better way? Tag: sony display driver Tag: 48779

    - high speed isoch => why number of packets has to be a multiple of 8 ? Hello, The hepl file for isousb sample driver in XP ddk says the following: " The number of packets sent down with each Irp/Urb pair should be a multiple of 8. " i have also tried and when it is not a multiple of 8 , packets do not go through . however i do not understnad the reason . Is this limit defined in any way by the USB 2.0 specification? If yes , what part of the spec? If not , then what is the reason for this limitation? could somebody please clarify this? thanks in advance regards Taha Tag: sony display driver Tag: 48778

    - Problem Modifing the NDIS packet Hi All, I am trying to modify the NDIS packet. I want to redirect the packet from destined for 172.10.10.10 to 172.10.10.10. steps taken to modify the packets. 1. Modify the Destination IP address. 2. Calculate the Checksum. 3. Modify the Destination MAC address. 4. Send the packet. I have used both Network stacking and own NDIS packets. When i tested my code, it worked on One Ethernet Adapter and it did not work on another adapters. I do not know why. When i captured the packet with Etherreal, it shows that the Checksum is 0 at the destination. Everything else is fine. I checked the IP address, MAC address, then are updated. I am calculating the right checksum and i made sure i am updating the checksum after i modified the packet. I am not sure, when Checksum became 0. I do not know, if Miniport driver made it 0. Is that the posibility? if yes then why? Is my checksum wrong? I am attaching the code to calculate checksum here. Thanks in advance for your help. Regards Rajesh /* ************************************************************************** Function: FltIPSumCalculation Description: Calculate the 16 bit IP sum. *************************************************************************** */ USHORT FltIPSumCalculation(USHORT len, PUSHORT pbuf) { ULONG sum=0; while(len > 1){ sum += *pbuf++; len -= sizeof(USHORT); } if(len) sum += *(UCHAR*)pbuf; sum = (sum >> 16) + (sum & 0xffff); sum += (sum >> 16); // one's complement the result sum = ~sum; return ((USHORT) sum); } Tag: sony display driver Tag: 48773

    - halftone settings in GDIINFO Hello printer driver gurus, I am currently working on a virtual CGM printer driver using the msplot example as reference. Since CGM is a device independent format it can handle RGB 24bits (8bits per value). To which value should I set the ulHTOutputFormat field of the GDIINFO structure? The msplot example shows that it is set to HT_FORMAT_4BPP, why? Thanks in advance, Theo Landman Tag: sony display driver Tag: 48772

    - ndis usb hi, i am writing a ndis usb driver(actually putting the sample codes ndiswdm and bulkusb together). it seems that the driver could send/receive the packet properly if it ignored the mac address of the incoming packet. But I just wonder how to determine the physical mac address of the target device in the initialization stage since the usb controller does not really have one??? Thanks.

    - about SCSI command Hi, I may post this message to a wrong place but I think I can get the answer here. I tried to send a SCSI command, Request Sense, to a SCSI disk logic unit, but there are two buffers, one is the data buffer and the other is the sense data buffer. Which buffer should be used for this command? I red in the document of SPC-2 and is still puzzled at it. It seems that the sense buffer is used only for autosense situation. As a result, I think I should use the data buffer. However, I could not make sure. Please help me. Thanks! Tag: sony display driver Tag: 48740

    - Malformed TCP packets I have an application that uses overlapped sockets. I run two instances of the application on different PCs; one instance connects to another, then both instances exchange some data. I am having troubles with certain PCs, which send out malformed TCP packets with wrong TCP checksums or IP headers partially overwritten by user data. The problem happens with Win2k SP3 machines, and SP4 seems to help. Now I have an XP SP1 machine (A) and XP SP2 machine (B). When A connects to B, all works fine. When B connects to A (i.e. A is listening), then some TCP packets coming out of A are malformed. When two instances of the appliction are running on A, all is fine. Other XP SP1 and 2003 machines work fine. So it must be something wrong with the machine A. Even if I did something wrong in my user-mode program, this woudn't affect the packet headers, would it? Is it possible to get the list of all the drivers in the TCP stack? I would then compare the stacks on A and B to see if there's any difference. Any other suggestions? Thanks.

    - CreateFile() on NDIS Protocol Driver failes for Regular User Accou Hi, I wrote NDIS Protocol Driver based on NDISUIO DDK sample. It works fine but only under "Administrators" accounts.

    - NdisMQueryAdapterResources() : resource allocation problem at WinMe Hi, I am stuck with a similar problem (as mentioned below in one of the older postings). Driver works with XP and 2K. Infact it works with WinME installed on PC where I use PCI-Cardbus(Ricoh) controller to insert my cardbus wireless lan controller. It doesn't work with WinME (on IBM Thinkpad A21m laptop). My NdisMQueryAdapterResources() returns only one resource i.e. interrupt. Using debugger command 'pci' I see that BAR seems to be mapped. No difference when I use NdisMPciAssignResources() wrt number of resources but here I get IO enabled in addition to BusMaster and Memory (i.e. control word 0x7 in NdisMPCIAssignResources() against 0x6 in NdisMQueryAdapterResources() . There is one imp print in the debugger in the reboot that follows crash because of pci-bar not getting mapped. It says"VPICD Severe Perf Warning: interrupt #9 is supriousing. Get the owners of the devices on that interrupt to look at their code." This problem exists till I don't shutdown the m/c and start. Device manager shows that 'SCI IRQ used by ACPI bus' is the interrupt that prompts that warning. My device is on interrupt 0xB. Don't know whether this problem is linked to above resource allocation problem. Hi Daum, Found you query in this ng. Did you get the solution for this ? I couldn't find post-followup-message in your posting hence creating a new thread. Went through "Another NDIS, PnP, PCI question" thread in "comp.os.ms-windows.programmer.nt.kernel-mode" which is related problem but changing eeprom contents from 'other controller' to 'ethernet controller' did not help.

    - Setting WPA key by OID_802_11_xxx Hello, I am trying to set WPA key using OID_802_11_xx OIDs. I set following OIDs in order OID_802_11_INFRASTRUCTURE_MODE to Ndis802_11Infrastructure OID_802_11_AUTHENTICATION_MODE to Ndis802_11AuthModeWPAPSK OID_802_11_WEP_STATUS to Ndis802_11Encryption2Enabled OID_802_11_ADD_KEY using output of PBKDF2("KT12345678",ssid,ssidlength,4096,256) algorithm (to get 256 bits key from "KT12345678" preshared ASCII key ) OID_802_11_SSID using ssid But there is something wrong with EAPOL 4-way handshake communication. AP stays in authentication phase so I can not get IP address from DHCP server. Do I use wrong key algorithm or my order of OIDs is not correct? I saw that people are sending two OID_802_11_ADD_KEY OIDs after OID_802_11_SSID OID and it works. Could someone tell me at which moment these two OIDs are sent and what is used as WPA key (preshared or output of PBKDF2 algorithm)? I do not understand who is responsible for WPA authentication, client software or wireless driver. If I send WEP key to wireless driver everything is Ok (driver takes key, authentication process is done by driver and I get IP address from AP) but with WPA it is not case.

On kernel streaming driver code: DriverEntry(IN PDRIVER_OBJECT DriverObject, IN PUNICODE RegisteryPath) { DriverObject->MajorFunction[IRP_MJ_DEVICE_CONTROL] = <ouriocontrolhandler> ... ... } Then we have a function: NTSTATUS OurIOControlHandler(IN PDEVICE_OBJECT DeviceObject, IN PIRP Irp) { irp = IoGetCurrentIrpStackLocation(Irp); controlCode = irpStack->Parameters.DeviceIoControl.UoControlCode; switch (controlCode) { .... <do our work here> } } However, on stream minidrive, DriverEntry( IN PDRIVER_OBJECT DriverObject, IN PUNICODE_STRING RegistryPath ) { HW_INITIALIZATION_DATA HwInitData; HwInitData.HwReceivePacket = MyReceivePacket; HwInitData.HwCancelPacket = MyCancelPacket; HwInitData.HwRequestTimeoutHandler = MyTimeoutPacket; <continue> ReturnValue = StreamClassRegisterAdapter(DriverObject, RegistryPath, &HwInitData); } So can I l put in the line (or is it safe to do so ?, will it be overwritted) : DriverObject->MajorFunction[IRP_MJ_DEVICE_CONTROL] = <ouriocontrolhandler> in stream minidriver ? what <StreamClassRegisterAdapter()> put in for this parameter (IRP_MJ_DEVICE_CONTROL) ? will it overwrite my parameters ? If I want to have my custom IoControl In minidriver, what is the proper way ? Note: Ref: TestCap DDK sample Thank in advance WP Tag: sony display driver Tag: 48697

    - passthu problem again. hi, a few days ago i posted a query regarding pasthru IM driver not transmittng larger packets. Mr. Thomas Devine pointed out the article at the following link : http://www.ndis.com/pcakb/KB05280101.htm, but even when i return NDIS_STATUS_NOT_SUPPORTED for OID_TCP_TASK_OFFLOAD in the MPQueryInformation() , the problem persists. any more suggestions ? i have a hunch that this has got something to do with MTU. when i access larger files across the network, the passthru sends the packets of the size of MTU and when i append my own headers, the size gets larger than the MTU and ultimately results in the rejection of the packet. can anybody tell me how i can make the top level network driver to send the packets with size a little less than the MTU so that i can accomodate my headers without exceeding the MTU for NIC ?? thanks in advance. regards.

    - Device_Description of IoGetDmaAdapter Hi all, From the Windows 2000 DDK Help, there is a brief description shows that the "MASTER" member of DEVICE_DESCRIPTION indicates whether the device runs as a busmaster adapter (TRUE) or a slave DMA device (FALSE). Would someone tell me the difference in details. Thanks. Clliman Tag: sony display driver Tag: 48695

    - Video streaming USB device driver based on USBCAMD and AVstream ar Hi, Im trying to develop a driver for USB2.0 camera. I was going through the Microsoft DDK site and it mentions that future driver development must be done with the Windows Server 2003 DDK. So, I have installed this DDK and on going through the samples have come across a driver for an Intel USB Camera. This sample is located in the "...\WINDDK\3790\src\wdm\videocap\usbintel\sys". folder. On going through this example I find that it is based on USBCAMD and on the "stream class" architecture. The "USBCAMD" is fine, but the "stream class architecture" is not. The DDK documentation states that the "stream class architecture" should no longer be used, though it is still provided. The document states that new video drivers must follow the "AVstream architecture". So, I was wondering if there's any way I could get a similar sample driver code for a Video streaming USB device based on USBCAMD and the AVstream class architecture. Please suggest. Thank you, Ravi.

    - request for info Hi, I'm hoping to find some help from you device experts. I need to find a way to catch events from a bar code scanner that is confiured as a keyboard wedge. It shows up in my device manager as a HID and I can open it using the HID functions. However, since it's a keyboard device I can't get read or write access (it's already locked by the OS). Can I still get notifications of events from this device after opening it (CreateFile) without read/write permissions? If so, please give me a hint. thanks very much, Deanna Tag: sony display driver Tag: 48677

    - Cann't set the packet filter... Hello, I am developing a miniport driver for Windows XP and want to set a the packet filter. But my machine crashes, if I set the packet filter via NdisRequest. I debuged my driver and detected that the error occures in "ndis!MSyncSetInformation". I think that MSyncSetInformation is a ndis function. Unfortunately, I don't know this ndis function and my driver doesn't call it. Have anyone an idea, why this fuction is called by my system? Why crashs my machine? Thank you in advance...

    - Re: Power Management in PASSTHRU Thanks Maxim. I think I found the thread you're referring to. There certainly was good information there. I now know, among other things, that MPHalt can be called without PtUnbind ever being called. Unfortunately, however, it didn't address my issue. I believe my question boils down to this: 1. Does NDIS serialize PNP events with respect to send/receive paths? 2. If not, is it a requirement that a packet does not leave the driver from an edge that is in low power? If the answers are 1)no and 2)yes, as I suspect they are, then I believe we have a bug in the PASSTHRU driver. As always, I am very grateful for any insight anybody may have on this.
