    - problems while using MmAllocateContiguousMemorySpecifyCache Hai; I am using MmAllocateContiguousMemorySpecifyCache() function to allocate the memory. then i map that meory to user space by using function ZwMapViewOfSection(). I build that driver, that driver is working is fine. I put my pci cards in any pci slot it is working. Today i put that slot in pcix slot in my pc. Then MmAllocateContiguousMemorySpecifyCache() functions succeeds, but ZwMapViewOfSection() fails.I dont know what is the behaviour happening. I show my function code below. MmAllocateContiguousMemorySpecifyCache (numDescBytes, phyAddrLowRange, phyAddrRange, phyAddrMultiple, (MEMORY_CACHING_TYPE)MmCached); ZwMapViewOfSection(physicalMemoryHandle, (HANDLE) -1, &(PVOID)virtualAddress, 0L, 2, &viewBase, &size, ViewShare, 0, PAGE_READWRITE | PAGE_NOCACHE ); I dont know why it is not working in pcix slot.Please tell me what are the possibilities.

    - NdisMAllocateSharedMemory, Bus logical address and Physical addre Hi We're developing a cardbus (dma master) NIC. I'm allocating shared memory in the Ndis driver using NdisMAllocateSahredMemory(). This call, gives me the virtuall address and physicall adress of the buffer. Now, How do I translate the returned physical address to a Bus logical address, which I can pass to my device.? Or Can the physical address reurned by the NdisMAllocateSharedMemory() be directly given to the dma master? Can a dma master use the physical address and access the system memory even if it has to go through PCI bridges.

    - How do i install/change a device driver by software? Hello. I am currently trying to create a setup, doing these things: 1. Copy some files 2. Copy a new driver for an USB to IrDA dongle to harddisk 3. Update the driver for the USB to IrDA dongle, using copied driver from point 2. 4. (?) Kill the standard Windows XP Driver to never see it again and force Windows to install the driver from point 3 _ALWAYS_. I have some Problems/Questions with this: 1. No problem here. Inno Setup 5.0.8 used. Setup is for Windows XP SP 2 only. 2. I have 2 files: .inf and .sys Where is the correct location in {win} for driver files? I am currently copying the driver to the new folder {win}\infrared, because the files are copied to the correct location, when the driver is installed. 3./4. Hm.. no realy idea here. I never needed to install a driver by a software before. I found nothing in the Inno Setup documentation, so i think i have to use external programs. I want to do: - Tell Windows to remove the current driver from Device USB\VID_[my VID]&PID_[my PID]* and install my driver instead, ignoring that the new driver is not signed. - Tell Windows to use this driver allways, when a device with USB\VID_[my VID]&PID_[my PID]* is deteced and never again install the standard windows driver for this device. I tested around with the Microsoft tool "devcon.exe" and tried this: >> devcon.exe remove *USB\VID_[my VID here]&PID_[my PID here]* >> rundll32.exe setupapi.dll,InstallHinfSection DefaultInstall 132 [my driver filename here].inf >> devcon.exe rescan Result: Windows XP seems to re-install the Windows XP standard driver for the device. But how can i force Windows XP to intall a different driver for the device? How can i force Windows XP to use this new driver always, when a new device with the same VID&PID is detected? If the device is deteced, i can do it via Windows: => device manager => open device, drivers tab => update driver => select new inf file to install => warning for windows logo but working But how can i do this via software setup? And how can i force windows to use this driver, when a 2nd device is detected? Note: There will be never any other IrDA device connected, so it should be no problem to "kill" the windows XP standard driver if required. Any help is greatly appreciated.

    - enabling tcp segmentation offload leads to poorer perfomance I am adding TSO support to a NDIS driver for win 2003. After TSO is enabled, the driver works fine, only that the performance becomes worse. Netperf TCP thruput drops by +30%. Logging shows that NDIS does pass big packets to the driver and packet trace shows that the card does split the big packets into small pieces. Nothing abnormal (no excessive retransmission, csum error) is observed in the packet trace. But why enabling TSO can degrade performance so much? I am pretty new in driver development and I know it's hard to tell without actually looking at the source code. but I really want some suggestions, directions from those gurus out there. Are there anything I should pay attention to? what tools, perfomance counters I can use/watch to help trace down the root cause?

    - multi-function USB drivers with IAD Hi.. I'm trying to get a multi-function USB device to talk with windows properly. One of the functions is RNDIS, which has 2 interfaces, along with a custom function with 1 interface. In my config, RNDIS is using interfaces 0 and 1, while the custom function uses interface 2. In the config descriptor, I use this IAD descriptor before the RNDIS interface (but not one before the custom interface): 08 0B 00 02 02 02 FF 09 The problem is that when I plug in the device, windows (XP SP2) doesn't detect it as a composite device and add the MI_xx field onto the id that it compares to in my .inf file. I set up a dummy config with 2 functions that had only 1 interface apiece and the composite driver loaded correctly, so my guess would be that the IAD is not being set up properly. Is IAD support in XP SP2? Are there debug logs I can look at to see what is going on? Do I have to set up my .inf file to load the composite driver somehow? thanks for your help, Ben Tag: Can user app determine if remote debugger is attached? Tag: 75628

    - Re-using a user mode DLL for implementing a HID joystick? Hello, I'm just playing around with an USB interface card ( http://www.velleman.be/ot/en/product/view/?id=351980 ). This interface card is controlled via calls to an (user mode) DLL (K8055D.DLL) for setting and getting the analogue and digital output/input. My idea is to use this card as a base for a custom build flight sim yoke. As far as I'm understanding the DDK docs, I will have to write an HID minidriver to get DirectInput to "see" the interface card as joystick device. Problem: The minidriver is a kernel mode driver. The provided DLL is user mode. So, I assume using the high-level (and comfortable) DLL calls out of the minidriver is not possible, isn't it? Is there a other solution than reverse-engineer and re-implement the low-level DLL to interface card USB communication to pretend the card to be a joystick for windows? Kind Regards, Horst.

    - ACPI and Thermal zones Hi I try to get the data of the ACPI thermal zones. Currently I don't know how. As far as I believe I must access the acpi.sys driver "in a way" to get the data. Unfortunately I dont know how. When I searched the web for references I found a program named "mobilemeter". This programm accesses the ACPI in a way and displays the thermal zone. It looks like this programm accesses the ACPI driver since no driver is shipped with this program... Hope anybody has a idea or example. I use VC++ for development... Thnaks in advance P.

    - netvmini sample bug? Hey, I just experienced a bugcheck in my NDIS driver in my MiniportInitialize() function. I had been inspired by the netvmini sample's use of the two macros MP_INC_REF() and MP_DEC_REF(). The latter calls NdisSetEvent() whenever the reference count has reached zero. However, this results in a problem in the MiniportInitialize() function. In the sample, one of the last things done in the function is to call NdisInitializeEvent(). But if initialization fails at an earlier point, NdisInitializeEvent() is never executed and when MP_DEC_REF() is called to clean-up memory a bugcheck occurs (as the event hasn't been initialized). What's up with that? Tag: Can user app determine if remote debugger is attached? Tag: 75602

    - PnPAddDevice Return Value Hello Everyone, I am trying to return a error value from PnPAddDevice routine of my PCI Device driver for the system to not load the driver for that particular device. I am trying with STATUS_NOT_SUPPORTED. I see that the AddDevice keeps getting called. The background for this trial is as follows: My driver is a PnP Driver and there is a legacy driver available for the same PCI device with different functionality. The system has 10 similar PCI devices and I want to load my driver only on two of them. I am using the PCI three-tuples BUS-DEVICE-FUNCTION for choosing my devices. But, for automatic installation we have to use the PCI VendorID and Device ID which is same for all the 10 PCI devices. If I try automatic installation, the system tries to load my driver for all the 10 PCI devices. So, I check for specific BUS-DEVICE-FUNCTION in my AddDevice and return STATUS_NOT_SUPPORTED. I expect the system to ignore my driver and allow the legacy driver to use the device. But, it does not seem to happen and my AddDevice keeps getting called. Is there any specific STATUS_* value I have to return from AddDevice to achieve what I want? Please let me know the value or point me to the place where I can get it from. Thanks in advance for the big help from all of you Best Regards, Raj Tag: Can user app determine if remote debugger is attached? Tag: 75600

    - Pre-loading USB Device Drivers I have a client who has created a USB device. The chipset vendor of the USB chipset provides a set of driver files. The drivers install correctly and everything is working so far. The customer would like me to have the primary software installation program pre-load the USB drivers so that if the user plugs in the device, Windows will automatically install the drivers without prompting the user for the CDROM, etc. The installation files that I have for the USB chipset is a series of INF files, dlls, and device drivers. Can anyone give me an idea of how I can pre-load these drivers on the user system to meet the customer's goal? Tag: Can user app determine if remote debugger is attached? Tag: 75586

    - Sending Irp from SCSI miniport driver to bus driver I have a bus driver similar to the toaster bus driver from the DDK. I create a PDO (by using an application to send IOCTL_BUSENUM_PLUGIN_HARDWARE), and then I load my SCSI miniport driver onto that PDO. My bus driver exports an interface that the SCSI miniport driver uses. In the SCSI miniport code, I want to send IRP_MN_QUERY_INTERFACE to the child PDO that corresponds to the PDO on which the miniport driver is installed. In the miniport code, I have been sending the IRP by using the code below, where targetObject is the DEVICE_OBJECT field of the DRIVER_OBJECT parameter passed to the miniport's DriverEntry function. I believe that targetObject would then correspond to the FDO (not the child PDO that I want), but, nevertheless, this was working with no problems at all. However, I recently switched to another test PC, and now I get Bug Check 0x35 (NO_MORE_IRP_STACK_LOCATIONS) on the call to IoCallDriver. 1) Any idea why I get this Bug Check? 2) Is there a way for the miniport driver to get the PDO pointer that I need?

    - SP_DEVICE_INTERFACE_DETAIL_DATA Are the following facts trivial? Maybe not trivial enough. In the C and C++ languages, if the name of an array is used in an expression then it usually converts to a pointer type, but not always. Also array types in function parameters usually convert. However, if an array is being defined and storage is being reserved for the elements, then the name of the array is the name of the array itself, and does not convert to a pointer. Let's hope those facts are understood by most device driver writers, so that they don't cause many blue screens. Let's hope. Let's hope those facts are understood by big software vendors who have been known to write device drivers.

    - "Driver" or "Interface Object" - yes or no? I am having the following debate: I am trying to convince a vendor that the proper way to provide an interface to their embedded system (that hooks up to a PC using TCPIP) is to provide a software component on the PC (like a driver). For some reason, they are of the oppinion that just providing the syntax for the messages that go back and forth should be enough (i.e. the actual data that corresponeds to a particular message in an agreed format). I believe that it is better software engineering to provide an encapsulation and buffer layer in shape of a software component (such as a DLL etc.). Am I right? Wrong? How do I convince them?

    - PS/2 Mouse Packets and USB Mouse Reports under Windows Vista Hello Everybody, Back in 2004, Microsoft said that Vista was going to support the new WM_MOUSEHWHEEL message for horizontal scrolling (tilt wheel), which implies that tilt wheel data will be part of the standard data packet sent by a mouse to the OS. Does anyone know if any information has been published about the standard PS/2 packet structure for a mouse with a tilt wheel? Will there be any other information contained in the new packet format, such as the 4th and 5th buttons? If there are more buttons, what functionality is expected from them? How should a tilt-wheel PS/2 mouse report itself to the system to inform that it supports the new packet structure? Has any information been published about HID usage pages and usages to be used to transfer tilt wheel values to the OS over a USB connection? Any leads will be greatly appreciated. Thank you!

    - pci expansion support I have finally found some time to rewrite a filter driver for a pci expansion system. Given the product I have a requirment to increase the resource windows of buses that are upstream of my product, because the system may be hot plugged, some BIOSes don't support us, and some of the devices downstream (third party) may require more then the default 64MB/64MB/4K. My driver acts as an upper filter to PCI.SYS. I would like to modify the PCI config space of the upstream buses before PCI.SYS reads them. The information I am looking for is at what point in the process does PCI.sys read the config space before resource arbitration to decide what resources to allocate? I will figure it out through expirimentation, but if someone out there has some street knowledge, or can point me to some relevant documentaion in this area that could save me some time I would appreciate it. The driver I am replacing makes modifications in the IRP_MN_FILTER_RESOURCE_REQUIREMENTS pnp IRP, this is a direction I could go as I have a mostly working example, it just seems like modifying the config space and letting PCI.sys do its job is an cleaner route to take. My worry is that I have somewhat of a chicken and egg dilema as I need pci.sys to make modifications to the config space, but I don't want to make the modifications too late. I want to work within the accepted practices of the OS as I want the driver to support Vista and 64 bit versions as well without too many modifications.

    - IoCallDriver() returns STATUS_INVALID_DEVICE_REQUEST 0xc0000010 Hi All, I have a problem formatting and sending an Irp with Urb. I have an usb upper function filter driver and inside my custom IOCTL handler I call UsbBuildSelectConfigurationRequest to format an Urb and then I call SendAwaitUrb to sumbit the Urb. However, IoCallDriver inside SendAwaitUrb is returning STATUS_INVALID_DEVICE_REQUEST 0xc0000010. I must be wrong somewere in the code below, because as we all know the SendWaitUrb and the other code from W.Oney's book is a great source to learn and practicise. I have checked the chain Fido->Fdo->Pdo, it's ok, I believe UsbBuildSelectConfigurationRequest with NULL formats a proper setup packet... but still I am stuck and could not go ahead. Please take a look at the code below and let me know what do you think.

    - Sample Mirror Driver Excel Problem. I believe this problem has been around for some years now as I did find one other posting about it from November, 2002. When the sample mirror display driver that is included with the DDK is loaded (i.e. attached to the desktop), Excel displays the following error when it is started: "Not enough system resources to display completely." I strongly suspect this error is a catch-all for several issues and that the problem here is not necessarily due to the driver's taking resource but with something the driver is, or is not, doing that Excel expects/needs. Note that Excel runs after acknowledging this error message. However, it pops up often, for example when simply clicking on a different worksheet tab. So I am hoping this problem has been solved/identified by now and I would greatly appreciate any information anyone might have about it.

    - Mounting on a directory Greetings, I'm looking for some help with mounting a file system on a directory via SetVolumeMountPoint. I have a file system that I'm porting to Windows. In general it mounts OK, but I have one strange error condition that manifests itself as follows: 1) format a partition with my file system 2) use SetVolumeMountPoint to mount the file system on an NTFS directory << at this point the file system is NOT accessible via the NTFS path >> 3) reboot the system << the file system IS accessible via the NTFS path >> As a variation, if instead of rebooting the system in step 3, I use the Disk Management tool to assign a drive letter to the partition with my file system, it somehow makes the file system accessible via the NTFS path... It feels like my file system is not handling some event properly, but I can't figure out what it is... Anybody have an idea on what's needed?

    - SetupDiCallClassInstaller Intiating driver install then failing. Hi, this question has to with the installation and loading of a driver. The installation code I've written works great for Windows XP but not for Windows 2K. I used w2k for the building with the latest DDK. There is no hardware involved so my application calls the Setup API functions to communicate with the PnP Manager. So the adding of the devices is done when a user adds another port, not when the user installs the software. These devices are enumerated in ENUM\ROOT\PORTS. I have a virtual serial port (Com Port) driver I've written that can have up to 255 virtual devices. I have the .inf file and the .sys file in a subdirectory of my application. When I add the first port from my application it gets to the SetupDiCallClassInstaller function and it is called. The PnP Manager then loads my driver and calls DriverEntry. DriverEntry returns STATUS_SUCCESS but the PnP Manager calls my unload routine right after this. SetupDiCallClassInstaller returns stating a reboot is required. On Windows XP the AddDevice routine is called after the successfull call to DriverEntry with no request for a reboot. If I do reboot then everything works great. What is different from wxp and w2k in this scenario? Is there something in the deviceobject that needs to be set. I have Debug Prints in the PnP dispatch routines and none are being called. setupapi.log looks like this: @ 13:54:31.914 : Install Device: Begin. @ 13:54:31.914 : Doing full install of ROOT\PORTS\0000. @ 13:54:31.914 : Install Device: Writing BASIC Logical Configs @ 13:54:31.914 : Install Device: Changing registry settings specified by INF(s). @ 13:54:31.924 : Install Device: Writing driver specific registry settings. @ 13:54:31.924 : Install Device: Installing required Windows services. @ 13:54:32.785 : Install Device: Writing drive descriptive registry settings. @ 13:54:32.795 : Install Device: Calling RunOnce/GrpConv items. @ 13:54:32.795 : Executing RunOnce to process 5 RunOnce entries. @ 13:54:32.815 : Device install finished successfully (ROOT\PORTS\0000). @ 13:54:32.815 : Install Device: End. @ 13:55:02.017 : Device install function: DIF_PROPERTYCHANGE. @ 13:55:02.027 : Executing class-installer. @ 13:55:02.027 : Completed class-installer. @ 13:55:02.027 : Executing default installer. @ 13:55:15.166 : Device required reboot: Device has problem: 31. @ 13:55:15.176 : Completed default installer. Why does w2k require a reboot and not wxp? Problem 31 states that my driver depends on another driver that is not loaded? My driver is not dependent upon another driver? Anyone have any ideas as to what is going on? -David G Tag: Can user app determine if remote debugger is attached? Tag: 75469

    - Question about completion routine for InternalDeviceControl. Hi, does anyone know how to have the completion routine for InternalDeviceControl set up properly so that the routine will be called when the kmdf request object is completed by lower drivers? I set it up according to kmdf help file and the driver will only execute the routine twice before device manager will stop the driver completely. And I used the following two lines WdfRequestSetCompletionRoutine (Request, completionRoutine, devExt); ret = WdfRequestSend (Request, Target, WDF_NO_SEND_OPTIONS); to register a completion routine that just print out the text message and called WdfRequestComplete(Request, Params->IoStatus.Status) to complete the request. Thanks. AL. Tag: Can user app determine if remote debugger is attached? Tag: 75464

In an user application, is there any means for it to determine if a remote
debugger is attached and if so what means of communication (i.e. COM or
1394) it is using that will work on Windows 2000? The
CheckRemoteDebuggerAttached () seems to be the function to call if KD is
running on a remote system, but it only shows support in XP SP1 and beyond.
What we need is a means to achieve the same test which will work for W2K as
well.

Any help will be greatly appreciated!
