    - 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: How to play sound in Avssamp?? Tag: 48740

    - Where can I download a Drivers-Finder? Where can I download a Drivers-Finder? Is that possible to download a Drivers-Finder software to probe drivers (most them are: motherboard chipset, sound, display, network) from a machine, after formatting this machine, i can reload the drivers i kept from the Drivers-Finder program? any answer or suggestion is appreciated. mark msgmark@hotmail.com Tag: How to play sound in Avssamp??

    - 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. Under normal user ("Power Users", "Backup Operators") CreateFile() fails with error 5 (access denied). NDISUIO does the same. I called MS Technical Support and the guy there trying to tell me that all communication drivers work only under Admin.??? Does not seem to make any sence. After unsuccessful programmatic attempt to AdjustPriviledges() LogonUser() ImpersonateLoggedonUser()... I have tried to change INF, but with no success (I could be wrong there).

    - 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.

    - DrvFillPath Hi When Windows calls my DrvFillPath function of my printer driver, it passes (sometimes) more than 6000 subpaths (MoveEx, Polyline, Polyline, CloseFigure).... so my question now: Where does this come from? Just from one command? Or did the creating application call the FillPath fuction several times? ... 6000 times? Or how's this handled? So, when I'd like to write a test application that creates me that many subpaths and just one DrvFillPath call... what do I have to do? thanks MR Tag: How to play sound in Avssamp?? Tag: 48711

    - 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.

    - Custom DeviceIoControl Handling in Stream Minidrive ? (shared memory user - kernel) Hi, I have the screnario as below : I need to have custom IoControl code to communicated with user-mode application, I know how to to it in non-minidriver kernel mode, but how about in stream minidriver ? 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: How to play sound in Avssamp?? 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.

    - 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.

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: How to play sound in Avssamp?? Tag: 48677

    - 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.

    - IoBuildPartialMdl bluescreen I allocate 'targetMdl' of 2048 bytes and then build a partial Mdl to map 2048 bytes. I get blue screen like " not large enough to map the entire range of addresses". If I want to map 2048 bytes, is mapping Mdl of 2048 not enough. Following prints clearly show I used AllocateMdl 2048 bytes and PartialMdl 2048 and blue screen error. If I allocate 4096 and then BuildPartialMdl with 2048, everything works fine.

    - NDIS Prism2 I am looking to add some functionality to an 802.11 card so that I may put it into some of the test modes that the firmware supports but windows doesn't. what do I need to do/where should i look to get example prism2 chipset NDIS miniport code. I feel like it should only be a minor addition to the driver to make it work, but I don't want to have to write the driver over from scratch. any thoughts/help would be greatly appreciated. thanks, brad Tag: How to play sound in Avssamp??

    - dumping packet contents from USB driver for debugging Hi, In my usb driver , i have ot communicate isochronous data to a USB device . Before calling the IOCallDriver for the lower level Windows provided drivers , i make the requiest packets , and fill the usual structs etc including Urb.UrbIsochronousTransfer.IsoPacket[]'s length and offset parameters , but the memory they are using is in an MDL structure . Is there a way to dump the content of each packet in the IsoPAcket array , into a debugger? Can this be done by enabling the tracing level of any lower level windows USB driver stack component? can and should this be done is my USB driver? regards Taha Tag: How to play sound in Avssamp??

I renamed them to unidrv.dll,unidrvui.dll. Now I went to the XP ddk and built the koemuni.dll. I tweaked up the oemdll.inf in the \oemdll directory of the XP ddk to point to the koemuni.dll instead of oemuni.dll. Now I do the Add printer steps and finally it lands with a failure dialogbox on windows 2000 saying:- --------------------------- Add Printer Wizard --------------------------- Printer driver was not installed. Operation could not be completed. --------------------------- OK --------------------------- "D:\WINDDK\2600\src\print\oemdll\oemdll.htm" says:- "However, the Windows NT® 4.0 printer driver files will either need to be copied to the local directory containing Oemdll.inf, or during installation, you will need to point to the location where these files may be found. For the kernel-mode samples to work, the kernel-mode drivers (the Windows NT 4.0 drivers) used most support COM OEM Printer Customization DLL extensions, while the driver files in Windows NT 4.0 Service Pack 4 and earlier do not."

    - how apc work? I've read that after kernel has queued apc in destination thread it request software interrupt at apc level. All threads execute at irql<=1 so how is it made?. Is it that nothing happens with apc queued calls until irql drops below 1(to 0) to start apc interrupt and than we are in some thread. What will happen if apc is in other thread. Is kernel checking all threads in system for threads with apc and executing them and after processing all apc releases interrupt or how it works? Tag: How to play sound in Avssamp?? Tag: 48581

    - printer driver -> font much too small Hi In the DrvTextOut function of my virtual pritner driver I'd like to calculate the font size (in device units) that I have to pass to the CreateFont function to replay the recorded print job. Now... how do I calculate this? like this: IFIMETRICS *ifFnt = FONTOBJ_pifi(pfo); XFORMOBJ *xFrmObj = FONTOBJ_pxoGetXform(pfo); XFORML xFrm; XFORMOBJ_iGetXform(xFrmObj, &xFrm); float eXScale = sqrt(xFrm.eM11 * xFrm.eM11 + xFrm.eM12 * xFrm.eM12); float eYScale = sqrt(xFrm.eM22 * xFrm.eM22 + xFrm.eM21 * xFrm.eM21); int SizeInDeviceUnits = (int)(0.5 + (eYScale * ifFnt->fwdUnitsPerEm)); well, this code is not invented by me... I got it from http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q264243 ok, they calculate the point font size... so the Size they calculate is iTmp = (int)(0.5 + eYScale * fwdUnitsPerEm * 72) / sizLogResPpi; Now the problem: The calculatet font size is about 10% too small. ... can someone explain me why? I mean, 10% is not nothing... could this have to do with the resolution of my device? ... any ideas how to find out what's wrong here? thanks a lot MR Tag: How to play sound in Avssamp?? Tag: 48578
