    - driver compile problem Hi, I am writing a WDM video capture driver by Win2000 DDK and VC6.0. My environment is Windows98 se. I put my source code under c:\xxxxxxx\wdm.nt directory, then build the source code. The generated .sys works well under Win98/ME, but it crash the win2k/xp immediately when it starts. Later I rename the directory to c:\xxxxxxx\wdm1.nt, (one more character), it works well on all Windows OS. My question is: Does it have any relationship between the source code directory name and generated .sys file? Or it is VC linker's problem? Tag: Where should KDevice::CreateLink() be called from?

    - Blocking in IRP_MJ_WRITE, KeDelayExecutionThread, threads I have a question about KeDelayExecutionThread(). Do I understand the documentation correctly: If I call KeDelayExecutionThread() to block in my IRP_MJ_WRITE handler, and the thread which called WriteFile() is terminated by TerminateThread(), will Ke... return immediately, no matter what I specify for the Alertable parameter?

    - Error msg upon adding printer Hi, I am trying to install my custom printer driver via the Add Printer Wizard. Upon clicking on Finish, I get an error message saying: "Printer Driver not installed. Operation could not be completed." My .inf file installs 3 files: a graphic DLL, a UI DLL and a print processor. Error messages in setupAPI.log complained about the files not having digital signature information. This also happens to samples that come with the DDK. Does anyone know why I get the error message and how I can fix it ? Is it a must to have the DLLs properly implemented ? My goal at this stage is to install my print driver that does nothing. Regardless of what it does, I want to be able to install it at least. Many thanks, Michael. Tag: Where should KDevice::CreateLink() be called from? Tag: 31700

    - USB Bulk In&OUT each need two handles? Hi If my usb device has two endpoints - Bulk_IN and Bulk_OUT. I try to use the bulkusb sample code within windows 2000 ddk to communicate with my usb device. According to the sample code, it seems that I need to use two GUID based string plus the "\PIPEXX" string to CreateFile() in test application and get back two handles, one for Bulk_IN and the other for Bulk_OUT, if I need to bulk-in & bulk-out data to device. My question is that can I use one handle to bulk-in and bulk-out data ? If yes, which way is the best way and what can I do? ps. I try to use GUID based string but not plus the "\PIPEXX" string (for example, "\PIPE00") and CreateFile() is successful. The handle I got can used to send DeviceIoControl(), but can't used to WriteFile() ( or ReadFile() maybe) and gets the error code ERROR_INVALID_HANDLE.

    - Power Management fails with the USB 2.0 host controller Hi, We have USB to Serial port converter. We have written windows-2000/XP WDM driver for that device. The 2000/XP WDM driver is working fine with all the serial port applications. When we receive PowerDeviceD1,PowerDeviceD2 or PowerDeviceD3 we are stopping the all the USB transactions. And configuring the device (Setting the registers and starting the USB transsactions) when the we receive PowerDeviceD0. When the systems comes out of the standby mode, my device (Application) works fine with the 1.1 hostcontroller. But the same thing is not happenning with the 2.0 hostcontroller. i.e My device doesn't work when system comes out of standby mode. I Debugged this issue and I found that VendorCommands (For Configureing the device registers) and Usb Bulk requests are failing when we are processing the PowerDeviceD0. That is why device is not working properly. URB status is 0x80000300 with VIA2.0 Hostcontroller URB status is 0xc0000005 with NEC2.0 Hostcontroller Operating system used windows-2000. Does anyone have any idea why this not work? Thanks in advance B. Madhukar Reddy Tag: Where should KDevice::CreateLink() be called from? Tag: 31693

    - NDIS Intermediate driver for CE To whom it may concern, I am desperately looking to find example code to write an NDIS Intermediate driver for CE. I found IMSamp.exe, which contains examples for desktop platforms. However, my understanding is that the NDIS IM driver for CE is different. Thus, any help that you can give me will be greatly appreciated. We have purchased MSDN Universal support under bryan.glancey@mobilearmor.com.

    - Question regarding netvmini NDIS driver! Hello, I am a NDIS newbie, I was trying to understand the NDIS device driver and write my own. For that I am going through the netvmini ndis driver source code, in the DriverEntry routine, the global variables are being initialized, and the comment says that "GlobalData structure is used to track the multiple instances of the same adapter". What does this mean? In which scenarios we might be having multiple instances of the same adapter running? Also, why do we initialize the GlobalData before registering the unload handler (I know the comment says that "unload handler has a more global scope"??)? Any help in this regards would be highly appreciated. Regards, Tar Tag: Where should KDevice::CreateLink() be called from? Tag: 31640

    - NDIS IM & Miniports & Bluescreens & how to support Hello, There is a well known problem between NDIS IM and Miniport drivers where the addition of the IM causes the Miniport to bluescreen. The solution is always upgrade the miniport to the latest, which has solved the problem. My problem as a vendor shipping an IM is when our product is installed the bluescreen happens so it is our products fault. Our support folks don't like having to tell customers to go get the latest driver from their NIC vendor. When I have looked at the fault it typically is a pointer dereference of an information buffer in a get or set oid. Does anyone have any idea what the underlying problem is with the minport. Why does it work without the IM? Is there anyway for the IM to protect against such problems? Thanks in advanced. Regards, Michael Wright Tag: Where should KDevice::CreateLink() be called from?

    - NDISUIO problem, can't retrieve NDIS packets Hello, I am using the NDISUIO sample and have successfully installed it under WIndows 98. I have got everything working, binding, querying OIDS and so forth but as soon as I try to read packets I get the right size for the data packet but the data itself is full of 0xAF(HEX). I have used both the MJ_READ method and a IOCTL command to retrieve the buffers into user space but both give the same result. I think it is going wrong when retreiving the actual NDIS buffer but the code for this is all Microsoft. Can someone point in the right direction? Maybe I am building the sample incorrectly?

    - How does Windows detect devices on the 1394 bus? Maybe a stupid question, but here it goes: I am aware that plugging or unplugging a device on the 1394 bus will result in a bus reset, and subsequently all devices and hosts will announce their presence on the bus. But does Windows also poll the bus? What if - hypothetically - a device was able to dynamically change its identity (by changing its serial number or whatever)? How does Windows detect the new device? Best regards, Martin Tag: Where should KDevice::CreateLink() be called from? Tag: 31597

Please bear with me as I am not really a software designer although I have some experience with debugging and modifying NT kernel drivers. I am now trying to go through a huge pile of documentation on the MSDN site, but I have a feeling that this will take forever unless someone could guide me.

    - Mapping of open TCPIP connections to owning processes? How can I do this on other system besides XP ? I found a framework that says you can do this on NT, Win2000 and WinXP but it costs a fortune. Should this be så hard to do? Thanx Zuka -- p.s.

    - 1450 Insufficient system resources ... when calling WriteFile w/large chunk. The code pasted below generates the following error 1450 Insufficient system resources exist to complete the requested service. ERROR_NO_SYSTEM_RESOURCES when it writes an approximately 64MB block of data to a file share. The source and destination systems in the test were Windows 2000. The source system running the program below is running SP3, and the destination system with file share is SP4. I don't think the SP's matter as I tried other tests with others sytems. My **guess** is that the source system's Workstation and/or file sharing drivers cannot handle the 64MB request from sent from the WriteFile API. This is a guess so any hints are welcome. A workaround is to send smaller chunks, and that's fine, but I thought it was worth seeing if anyone had thoughts on this. Since error 1450 is used in so many scenarios, it seems that the answer lies in Microsoft's source code or with someone who's familiar with this problem and/or internals causing this.

    - A driver with a few different devices (One PCI CARD) Hi all, I have a PCI card, which has a few differenrt sub units (Comunication ports, D2A, A2D, etc.). From the PCI BUS point of view, it is one device with one function. I want to create different device for each sub unit (4 typeA, 2 TypeB, 1 D2A, etc.). I already have an NT 4.0 device driver, which woks fine. Each sub unit has it's own device. In Driver entry we create multiple devices. The questions are : What is the best way to approach this under WDM ? If I create multiple devices in AddDevice, will it cause any trouble ? Does win-2000 expexts ONLY one device to be created in AddDevice routine ? For example : will win-2000 send power management to each of these devices or only to one of them ? Someone told me that I should write a BUS driver (toaster example). Is that true ? Any code examples ? Thanks Maurice Tag: Where should KDevice::CreateLink() be called from? Tag: 31422

    - Kernel mode debugging - a very basic question I have windows xp and the latest DDK Tools, i'm working on a Filter-hook firewall and i've reached a point where debugging is a must. first, to debug kernel-mode drivers, do i have to do it using 2 pc's(remote debugging) if yes, then what hardware do i need to debug my driver, i have a lan between 2 pc's, is it enough second, is there someway to get results(simple test messages) from my driver without using remote debugging. i tried debugging the user-mode client program, but DbgPrint() calls in the driver didn't work! i think it needs a kernel-mode debugger.

    - Win2003 DDK (3790) bug: No LCD backlight IOCTLs for wnet build environment? The Windows Server 2003 build environment does not properly define IOCTL_QUERY_SUPPORTED_BRIGHTNESS and other IOCTLs/structures associated with the LCD backlight power interface. (According to the DDK documentation, these should be in \WINDDK\3790\inc\ddk\wnet\ntddvdeo.h). These structures and IOCTLs *are* properly defined for the Windows XP build environment, in \WINDDK\3790\inc\ddk\wxp\ntddvdeo.h. From the DDK documentation for IOCTL_VIDEO_QUERY_SUPPORTED_BRIGHTNESS: The header file used to build applications that include this functionality, Ntddvdeo.h, is included in the Microsoft Windows Driver Development Kit (DDK). For information on obtaining the DDK, see www.microsoft.com/ddk/. Requirements Client: Included in Windows XP SP1. Server: Included in Windows Server 2003. Header: Declared in Ntddvdeo.h. Either the documentation is incorrect in stating that these features are available under Windows Server 2003, or ntddvdeo.h is incorrectly omitting them for the wnet build environment.

    - Win2K device driver wizard doesn't find the device names in my INF file I have an installable network device driver that is working fine, but there must be a problem with the INF file. If I choose a specific driver for Windows 2000 to install, and click Have Disk, I get no devices listed. If I let windows do it, there's no problem. If the driver is already installed, the device choices show up in the list. (not very useful at that point!) The INF looks correct and complete. How can I tell why Win2K is rejecting this as matching hardware, only in this one scenario? How do I start to debug? Tag: Where should KDevice::CreateLink() be called from? Tag: 31405

    - IOCtl Problem. Hello, I am writing a driver to create a virtual disk partition using some RAM. Driver is installed properly and a symblic link at \DosDevice\F: is created. But when I start using this partition I get an error message, "F:\ is not accessible Incorrect function." After debugging through the code I found that my DispatchIOCtl() is getting following IOCtl's calls repetedly, IOCtl command = 0x00074804 IOCTL_STORAGE_MEDIA_REMOVAL IOCtl command = 0x00070024 IOCTL_DISK_IS_WRITABLE IOCtl command = 0x00070000 IOCTL_DISK_GET_DRIVE_GEOMETRY IOCtl command = 0x0007405C Unknown IOCTL IOCtl command = 0x00074804 IOCTL_STORAGE_MEDIA_REMOVAL I tried to find out the command using CTL_CODE of ntdddisk.h, but getting Function value 0x0017 which does not exist. I am not able to figure out what's the flaw here? Could you please let me know what is going wrong here. Thanks in Advance, ~rushikesh. -- ---------------------------------------- Rushikesh Patil.

    - In my IM driver, can I find which process has sent a network packet ? I'm after mapping TCPIP connections to owning processes. Is there a way ? Also I know about a way to do this in user space, through iphlpapi.dll, but this only works with XP. Is there any way this can be done under other Win systems? TIA -- p.s. Back from the kolotechina to kolotechina Tag: Where should KDevice::CreateLink() be called from? Tag: 31402

In order to create a symbolic link to myDevice should
pmyDevice->CreateLink() (Class myDevice derived from base
class KDevice) be called from myDriver::DriverEntry() or
from the device Constructor myDevice::myDevice()? The
SoftIce DriverWorks documentation does not specify.

Thanks.
