    - Multi-interface USB Device : how to get a endpoint handle ? Greetings, I am writing a lower filter driver for a USB device, and I need to write some data to it. How can I get a pipe handle to an endpoint ? In most of cases, you can get them while choosing a configuration, by calling USBD_CreateConfigurationRequestEx. The problem is that my device has one configuration, several interfaces, and my filter driver is installed for only one of them. So I can't use USBD_CreateConfigurationRequestEx. Is there another way ? Tag: DIFx problem about preinstalling case on X64 Tag: 73702

    - How to implement the pending mechanism between KM and UM hi all, I am trying to implement a packet capture driver in DDK. Unlike netmointor, I hope the driver could capture the packet to application real-time. So I implement an event, generated by driver, to indicate the application to get the captured packet from driver. In order to reduce the overhead in keeping the captured packets, I use a buffer pool in driver to contained the packet temporarily before application read them. However, if the pool is full in the heavy traffic cases, the extra packet will lose. I find NDIS uses a PENDING state in its receive path. How can I implement the similar approach to cover the problem. Thanks! -Liang Tag: DIFx problem about preinstalling case on X64 Tag: 73662

    - Update PCI Latency Hi, I'd like to know how can I change the current PCI Device Latency of connected devices? I experience that most of modern graphic adapters have a very high pci latency value which causes problems on other PCI devices like USB chipsets etc. What I want to do is to offer an option to reduce the PCI latency of such devices. Now my questions: - How can I do this? I found some structures and API calls that mention these things, but I wasn't able to build me a proof-of-concept. - Is that propery way to manage this at all or should this be a task for the graphic adapter manufactureres (all of them)? The thing is that a lot of customers complain about instability of their PCs concerning high bandwidth/low-latency USB devices and quite often (more than we expected) the solution seems to be to decrease the PCI latency of the graphics adapter from 255 to 128 or 96. I experienced this with some of my firewire devices, too. IMHO I think this is not something one should leave to the end user. thanks for any advice in this doc Tag: DIFx problem about preinstalling case on X64 Tag: 73654

    - SetupDiBuildDriverInfoList problem with USB bluetooth? Hi, I need ti enumerate all USB bluetooth dongle with a particular VID/PID. We have our usb driver (not signed) and we also use the widcomm bluetooth stack. The bluetooth dongles are also compatible with the Windows XP SP2 stack. The main problem is: -I try to retrieve all the compatible driver for this dongle using SetupDiBuildDriverInfoList() -> it works. - Then I try to get the currently installed driver (by changing the device install params and calling again SetupDiBuildDriverInfoList()) -> it works only the first time. After that it says "no more items" I've checked with the Hardware manager and I've found that the Bluetooth device's icon changed and displays the "WinXP bluetooth icon" -> But the widcomm or our driver is still loaded and working! If I re-install the drivers, the icon goes back to the normal one. But as soon as I call again SetupDiBuildDriverInfoList() on this device, the icon change back to the WinXP bluetooth icon! This is not the case on a bluetooth device with a VID/PID not compatible with the WinXP stack. How can I avoid this problem? To reproduce this problem, it's simple: - Install a bluetooth device compatible with the WinXP stack using a other bluetooth stack (Widcomm for example) - Check the icon with the Hardware manager. - call SetupDiBuildDriverInfoList() on this device using default dev_install_params. - Refresh the hardware Manager and you should see the device with a new icon!

    - Problem! Interrupt service routine not executing after some interrupts generation Hi Everybody, Our PCMCIA 16 bit PC card(with WDM driver) is generating Interrupts properly and in the Interrupt service routine we are servicing immediately. If we does not service the interrupt then our device will stop generating interrupts. After some time Even though our device generated interrupt but ISR is not invoking. In this case we are not able service the interrupt becase ISR not executed. Then our device will stop generating interrupts. This kind of problem is coming when I move mouse or if i use keyboard. In IoConnectInterrupt routine Iam passing TRUE for Sharable interrupt parameter. What could be the problem? Is it a sharable interrupts handling problem? Please guide me. Thanks in Advance. Mahinder.

    - Printer Driver -- UniDriver pluginUI -- "DOCUMENT" Property Sheet Pages -- Questions Printer Driver -- UniDriver pluginUI -- "DOCUMENT" Property Sheet Pages -- Questions I am using function "IOemUI::DocumentPropertySheets". I am trying to add/remove "page dialogs" under "case PROPSHEETUI_REASON_INIT". I am NOT concerned at all about "OPTITEMS". I can successfully add my CUSTOM page dialogs using CPSFUNC_ADD_PROPSHEETPAGE, as shown in the "UI Plugin" example. Is this the correct way to add my custom pages? Should I be using CPSFUNC_ADD_PCOMPROPSHEETUI instead? Also, I would like to remove the two page dialogs that seem to show up automatically; page dialogs with names "Layout" and "Paper/Quality". I intend to replace them with custom pages that do something similar. The device(printer) property sheet page dialogs seem to work fine; I use function "IOemUI::DevicePropertySheets" for this case. Any ideas? Thanks, Rudy Tag: DIFx problem about preinstalling case on X64 Tag: 73596

    - Unsigned Virtual Driver - Multiple Instances Hi, I have a unique virtual NDIS Miniport driver which essentially creates virtual NICs in the sytem. Because of a no of reasons i will not be able to get this driver signed. This poses a problem in driver installation. Firstly i know that i will get the Unsinged Driver warning popup message (if the user has behaviour set to warn). My problem is that i want multiple virtual NICs that can come and go at any time. ( i have a virtual bus driver that creates PDOs whenever i want). Now if i have the NIC installed for 1 instance, when the 2nd NIC shows up Windows again asks where to install the drivers from. Why is this happening? I already have it installed and the 2nd instance shall just use the driver being used for 1st instance. This happens even if i turn the setting to ignore WHQL signatures. Also during installation the whole N/W stack for the 1st instance is tore down and driver is unloaded and reloaded (i guess since it copies a new driver file - happens even if i refuse to copy driver file). Basically i want the instances of the NIC to some and go silently without asking for installation again and again. (Although once i install 3 instances, they come and go silently but the 4th one again asks for driver). I cant go thru manual installation of 16 Nics in the begninning.I Dont even know how many will be enogh. Can a finite no of instances be installed at inital set up without even creating PODs for each one of them? Is it not possible to acheive with Unsigned Drivers or am i mising something. do i need to write a Co-installer, or somethig like that. thanks Pankaj Tag: DIFx problem about preinstalling case on X64 Tag: 73588

    - ZwCreateSection Hi All, I used ZwCreateSection() to create a section object in a kernel mode driver and tried to open the section object using CreateFileMapping() in windows. The problem is that both the driver as well as application will be updating the shared memory. So, when I tried to open the shared memory with FILE_MAP_WRITE specified in OpenFileMapping(), it returns win32 error code 5 (access denied). It succeeds with the FILE_MAP_READ access. If I use ZwClose() in the driver to close the section handle, I am able to use in the user-mode application. Is there any way I can specify in the kernel mode driver to make it possible to the user mode application too to write to the shared memory? I may be missing some flags in ZwCreateSection() or ZwMapViewOfSection() or InitializeObjectAttributes()? Besides writing to same memory from user-mode and kernel-mode in such scenario can result in any problem ( I suspect)? Tag: DIFx problem about preinstalling case on X64 Tag: 73585

    - Filtering disk IO when Windows hibernates Dear gurus, Could you advise how disk IO requests Windows 2000/XP sends during hibernate (or crash file dump) process can be filtered? In more detail, the problem is in the following. We work on software that transparently encrypts sectors on physical disks. My disk IO filtering driver works fine except the moment when Windows hibernates or writes crash dump file to disk. At that moment Windows does not use a regular well-documented stack of layered disk drivers. Instead, the operating system calls disk miniport driver directly. (Probably it would be more correctly to say - after sending IOCTL_SCSI_GET_DUMP_POINTERS Windows loads a separate copy of the driver and uses it for writing sectors.) As a result, our filtering driver cannot filter and encrypt the sectors Windows writes during the hibernation process. If someone knows how to filter these disk IO requests, the advice would be greately appreciated. Best regards, Sergey (I've read several topics on the matter in newsgroups, but could not find some concrete answer. As MSDN subscribers probably we should contact Microsoft, but is it really necessary and may help?) Tag: DIFx problem about preinstalling case on X64 Tag: 73583

    - Pdo creation problem I'm writing a bus driver which enumerates inserted flash memory card. (An PCI memory card reader device) After creating an pdo for the inserted MMC memory card (GenDisk), The disk drive driver can¡¦t be loaded correctly (there's an yellow mark on the "disk drive" in device manager, error code 31) Is there any a document or information to help me debug this? I need to know what's the problem between my pdo creation procedure & the WDF. Thanks! Tag: DIFx problem about preinstalling case on X64 Tag: 73581

    - problem with mixed bpp system In a multi-display system where the primary display is in 32-bit mode and all other displays are in 8-bit gray mode (non-palettized, linear), the display driver provides DrvBitBlt that will convert 32/24-bit source to 8-bit destination using NTSC weighting. Most drawing to the displays goes, as expected, through DrvBitBlt. However, not all code path seemed to go through that. Specifically, clicking the right mouse button on an 8-bit display and then selecting "Refresh" leaves a rectangular region that is rendered differently, using Windows' own way of converting 32/24-bit to 8-bit. Similar artifacts show up when pop-up descriptions pop down in the main file area of the windows explorer. Interestingly, the pop-up descriptions popping up for items on the left area (system Tasks, Other Places), do not leave any artifacts. How can one avoid those artifacts? Is there a way to provide this NTSC weighting to Windows to be used for all 32/24-bit to 8-bit conversions (XlatOBJ, PalOBJ)? Tag: DIFx problem about preinstalling case on X64 Tag: 73571

    - 8 bit display driver color conversion In the display driver/miniport, how can I make the OS call my DrvBitBlt with the 32/24-bpp source and let me convert it to the 8-bpp destination? Windows likes to convert the 32/24-bpp source to an 8-bpp one and then call my DrvBltBlt hook. Any ideas? Thanks Tag: DIFx problem about preinstalling case on X64 Tag: 73568

    - WPP tracing I am writing a file system filter driver. This is one binary driver build in windows 2000 enviorment and supports XP as well as 2003. This driver does lot of initialization activity in DriverEntry routine including creating device object. I was trying to use WPP tracing method, I refered the following article at OSR website http://www.osronline.com/article.cfm?article=376 . I could make tracing work but I would never get tracing messages in driver entry Is this a limit for windows 2000 driver. Thanks Ashish Tag: DIFx problem about preinstalling case on X64 Tag: 73563

    - Smartcard PC/SC IFD handler I need to implement a solution to have the Windows XP operating system accessing a smart card device. After researching the MSDN, I got to the point where I have to provide an IFD handler so that the Windows Resource Manager can access the smart card device, and that IFD handler is basically a Windows device driver. The smart card vendor provided a DLL that contains an API to access all the device functionalities, so I'd like to develop that IFD handler on top of the smart card vendor API. After starting to use the Windows DDK, I realized that the vendor API header file is not compatible with the DDK include files if compiling for kernel mode driver, but it is compilable for user mode driver. The question is: can I have a user mode driver as an IFD handler? Tag: DIFx problem about preinstalling case on X64 Tag: 73559

    - WinXP kernel symbol for ntkrnlmp.exe? Hi, I am trying to get the WinXP with SP2 kernel symbol for my system that comes with dual Xeon CPU. After pointing my windbg to MS symbol server, the message that I got is always no symbol available for ntkrnlmp.exe while symbols for other MS components work fine. Have anyone else got similar issue and able to figure out the issue? I have tried to download the WinXP symbols file that is available from MS webpage and install it manually on my system. And there is no matching symbol for the ntkrnlmp.exe either. Any help will be appreciated. Al. Tag: DIFx problem about preinstalling case on X64 Tag: 73558

    - Using SetPort to set a custom status Hi, I'm writting a printer driver. In the monitor, I need to set the status. The SetPort function from the API seems to be what I need. Indeed, it works pretty well if I use a predifined status. But when I try to set my own status, it does not work (the status is not changed at all...) Here is my code: PORT_INFO_3 PortInfo3; PortInfo3.dwStatus = 0; //No error PortInfo3.dwSeverity = PORT_STATUS_TYPE_INFO; PortInfo3.pszStatus = L"Test status"; //my status to display...

    - Mono print quality issue Hi, I have written a unidrv based printer driver for a USB printer. When I print a mono document at 600 dpi the quality differs for two prints. The text quality is differing in two outputs with the same printer driver. In one print the text are of good quality and are dark black and in second print the text printed are too light (grey colored). I have disabled the color optimization by setting dwColorOptimization (of ATTRIBUTE_INFO_*)to NO_COLOR_OPTIMIZATION in the call to the UI plug-in's DrvQueryJobAttributes function. (BUY I suppose this should not affect the quality of the mono print) Please suggest if there is any way to get the good quality consistently.

I had a DIFx problem about preinstalling case on X64. I use DIFx API to
preinstall/install/uninstall driver device. Installing and uninstalling
driver device is ok, but preinstalling it is failed. I look the result of
preinstall is successed because it returned value 0. But I plug-in the device
and it appear the dialog about Found New Hardware Wizard.The device is not
installed. Please tell me what's wrong and how to slove the problem. Thanks.
