    - Protocol Removal Is there an approved method for a driver to request the removal of a proprietary network protocol which is installed with the driver? The reason I ask is that I wish to change the interface name the protocol uses, and while the protocol gets installed with the driver, it does not appear to get uninstalled with the driver. When an updated driver is later installed, the protocol associated with it does not appear to get installed because the old protocol from the previous driver is still resident.

    - Will DMA transfer diable the CPU completely as if it has been revoved from the socket? Below is my understanding, but I am not sure of its validity. I hope to get some comments from you. Provided that a program want to start a DMA transfer. 1, CPU sends a start command to a DMAC (DMA Controller); 2, The DMAC signals the CPU through the HOLD pin and waits for the CPU's acknowledgement; 3, CPU signals the DMAC through the HLDA pin; 4, Upon receiving HLDA, the DMAC starts to DMA transfer. From now on, the CPU stops all its activities. Until the DMA process is finished, all the interrupts can not get responses. But, the CPU's internal status are kept, and all the interrupts' status are also kept. 5, Upon finishing the DMA transfer, the DMAC deactivate the HOLD pin, the CPU continues to execute its instructions. My question is the same as the title: Will DMA transfer diable the CPU completely as if it has been revoved from the socket? Tag: update: WDK 6000 build.exe dependency issue Tag: 92779

    - HID minidriver with multiple report descriptors Hi, I write a HID minidriver with standard Mouse and Keyboard report descriptors. It is based on vhidmini in Windows Server 2003 DDK. The driver work fine and I can read/write the report from the device. The Device Manager shows it is HID-compliant device in HID class, but the Mouse Class and Keyboard Class have none. How should I do so that it can be a mouse device and keyboard device? Should I modify the INF file? My driver's INF is almost same as the vhidmini's.

    - cancel-safe queues and Cleanup Assume a driver working with the same logic as the DDK Cancel sample implements. Suppose that one routine just removed a pending irp from the queue and then the Cleanup dispatch is called. Because the irp is not in the queue anymore, Cleanup won't find it and the irp won't be cancelled. In most cases this won't be a problem, the irp will be completed soon enough. But in some devices it is possible that the irp can't be completed for some reason. Then the irp would keep pending, possibly inserted again in the cancel-safe queue. In extreme cases the irp might be never completed, and it won't ever be cancelled either. Am I missing something, or do I need to take special care if irps removed from the queue might be not possible to complete? Tag: update: WDK 6000 build.exe dependency issue Tag: 92751

    - Propagating the Pending Bit "Any time a driver handling an I/O request returns the response of the next-lower driver, the value of the pending bit in its I/O stack location (SL_PENDING_RETURNED in the Control field of the IO_STACK_LOCATION structure) must be the same as that of the next-lower driver. " ...of course they are the same! "If the driver does not set an IoCompletion routine, the I/O Manager automatically propagates the value of the bit, freeing the driver of this responsibility. However, if the driver sets an IoCompletion routine, and the next-lower driver returns STATUS_PENDING, the current driver must mark its own I/O stack location as pending. " if the driver sets an IoCompletion routine, means it has sth need to cleanup before the irp is released, it is reasonalbe bcz device stack is a nesting arch. pls correct me.

    - ddkbuild.bat Vista DDK (6000) and making brower files (currently NOT) I searched for ddkbuild and DDK so I did my due diligence. We are upgrading from OSR DDKBUILD.BAT V5.1 to OSR DDKBUILD.BAT V6.10 and more importantly from DDK2600 to DDK6000. Yes I know, I know it was last released in 2002! The project is an XP NDIS 5.1 miniport driver. Now I am trying to coax a (*.bsc) file out of this and having no joy. The 6000 DDK says that I can not define: BROWSER_INFO=1 BROWSERFILE=drivername.bsc anymore. I saw some discussion from Mark Roddy about <ddkroot>\bin\verify.src and defining USER_ENV_BROWSER_INFO=1 to turn the error off but that still does not get me my drivername.bsc (no joy) It was in http://www.techreplies.com/drivers-43/visual-studio-net-driver-wizard-339156/ Does anyone know the magic invocations required to get a browse file. We really like using ddkbuild.bat and VS6 to manage the development environment. Thanks -Ron- Tag: update: WDK 6000 build.exe dependency issue Tag: 92740

    - PsCreateSystemThread on Win2k The DDK states that PsCreateSystemThread under Win2K must be called from the system process context only. However checking older DDK versions and older samples seem to condtradict that statement. This suggest that it can, but it shouldn't perhaps because it exposes a bug or a security hole in Win2k. So the question is if it is still possible to call PsCreateSystemThread from an abritrary process context, perhaps taking special precautions. Yeah, I know that I can schedule a work item to create the system thread. But this creates an overly sinchronization complication between the dispatch routines, the work item and the system thread.

    - Signing a Windows XP driver Hi, I'd like to sign our driver so it can be easily installed via the DIF for MSI. I tried several hours to obtain any USEFUL information on the winqual sites (which seem to be all updated for Vista, but I don't need Vista now). Usually posts like mine get answered by these two links: "Driver Signing Requirements for Windows" http://www.microsoft.com/whdc/winlogo/drvsign/drvsign.mspx "Summary of Windows Kernel-mode Driver Signing Requirements" http://www.microsoft.com/whdc/winlogo/drvsign/drvsign_perOS.mspx But actually these pages only circle around and everytime you want to follow a link "to see detailed information.." you end up on a page telling the same again (the first) or they are providing end user information (the latter) I once found something where the prices for a normal signing process were listed, but the procedure itself is still a mystery. So, I am lost in the depths of the weird half baked MSDN documentation (which only refers to vista). Can anyone provide a little step by step guide how to get my driver signed for Windows XP WITHOUT a full WHQL submission, distribution through Microsoft and logo stuff etc.pp. I just for now want that it installs on Windows XP without the warnings. thanks for any help and pointers doc Tag: update: WDK 6000 build.exe dependency issue Tag: 92715

    - Howto: find tdi behavior flag of a kernel sockets client Hello, Per WDK, a kernel sockets client can set a flag-- WSK_TDI_BEHAVIOR_BYPASS_TDI--that will cause WSK to bypass TDI filters. >From WDK: "If a native WSK transport exists for the address family, socket type, and protocol that are specified when the WSK application creates a socket, then, if this flag is set, the WSK subsystem ignores any TDI filter drivers and always uses the native WSK transport." How can I find out if this flag is set by a particular driver, or a particular kernel sockets client? Thanks. Tag: update: WDK 6000 build.exe dependency issue Tag: 92709

    - Virtual comport with usbser.sys Hello NG, I wrote an Inf-File which installs a virtual comport using usbser.sys for my USB device. When I connect the device to the PC the Hardware wizard comes up an installes usbser.sys. After that I can communicate with the device via a virtual Com-Port. So far so good. Now I tried this on several machines and now I am facing a problem on one of my testing machines. The driver on this machine seems to be installed properly but the Hardware wizard comes again and again. When I open the device manager the device appears under ports without an assigned Com-Port. Looking into the registry I found the entry \Device\USBSER000 which value is set to "COM11" under HKLM\Hardware\DEVICEMAP\SERIALCOMM but my device is not accessible via that COM Port (Com 11).

    - USB Compsite Device Driver loading and PnP events I have a question on the USB composite device. In DDK, it is said After the USB hub driver generates a PnP event for a Composite device with a set of compatible IDs that include USB\COMPOSITE, Windows searches the INF files in the inf subdirectory of the Windows installation (and, possibly, a vendor-provided floppy disk) for a match. If the device ID is matched, Windows loads the single driver that is indicated by the installation script and the generic parent driver does not come into play. If no device ID match is found, Windows uses a compatible ID, for which it loads the USB generic parent driver. I just want to know If the device ID is matched, Windows loads the single driver that is indicated by the installation scripts, then who will be responsible to generates PnP events for the multiple interfaces in the composite device?

    - help files in printer driver user interface In all previous versions of our printer drivers (for Windows 98, NT, 2000, XP) we used the WinHelp API to display context sensitive help for the printer driver user interface DLL. Windows Vista no longer supports the WinHelp functions, so I converted the driver UI to use HtmlHelp and rebuilt the old HLP files into newer CHM files. This does does not seem to work though. I can debug the driver UI and see that I am passing correct parameters to HtmlHelp() function, but nothing gets displayed. Is there some trick to using HtmlHelp from driver UI DLL?

    - Volume control implementation In this post I am referring to Windows 2K/XP, things seem somewhat different in Vista and I haven't had a chance to investigate it] There is volume control in Windows Media Player (or Winamp, or any other player application) and there is one in Windows control panel. Can anyone explain what each of them actually does? My current understanding is that volume control in the player makes player application scale audio stream programmatically, after which audio stream is sent to the hardware. Volume control in the Windows Control panel doesn't change audio stream programmatically but instead works as a "knob" for hardware amplifier on the sound card. Am I correct?

Here is the code ... static PCALLBACK_OBJECT unloadCallbackObject; static PCALLBACK_OBJECT testCBO; void initCallbackObject(void) { NDIS_STATUS status; UNICODE_STRING unloadCallbackObjectName; OBJECT_ATTRIBUTES unloadCallbackObjectAttributes = {0}; // register a callback handler RtlInitUnicodeString(&unloadCallbackObjectName, L"\\Callback\\UnloadCBO" ); InitializeObjectAttributes( &unloadCallbackObjectAttributes, &unloadCallbackObjectName, 0, 0, 0); status = ExCreateCallback( &unloadCallbackObject, &unloadCallbackObjectAttributes, TRUE, // create FALSE); if (status == STATUS_SUCCESS) { // created ok so see if we can open it ... status = ExCreateCallback( &testCBO, &unloadCallbackObjectAttributes, FALSE, // open FALSE); ... this test open always fails! ... however, if I change create flag to true this call will succeed, even though it should in theory fail because the object should already exist!

    - BulkUSB / ReadFile Currently, I am using the BulkUSB driver sample in the Windows DDK 2600.1106. For the user-mode application, I have been following the sample in the rwbulk.c (bulkusb\exe) - using API functions like ReadFile(), WriteFile() and DeviceIoControl() to communicate with the USB reader via the driver. In my application, I have allocated a Buffer of 1024 bytes (the maximum number of bytes supported by the firmware) and the nNumberOfBytesToRead is assigned to 1024 bytes. ReadFile(hFile, &Buffer, 1024, &dwBytesRead, NULL); I have always been able to read the data from the reader. However, when my colleague tried reading 1 byte of data at a time in a while loop, there would be an error returned from the driver for the first ReadFile(). for ( ; ; ) { if (ReadFile(hFile, &chRead, 1, &dwRead, NULL)) // A byte has been read; process it. else // An error occurred in the ReadFile call. break; } } In the BulkUSB_DispatchReadWrite routine, the driver will send a request to read 1 Byte of data from the reader. However, in the driver read completion routine (BulkUSB_ReadWriteCompletion), the Irp- >IoStatus.Status was 0xC0000001 (STATUS_UNSUCCESSFUL) and the Irp- >IoStatus.Information = 0. >From the CATC trace, the reader returned 5 bytes of reply for the Bulk- In request (even when the driver requested to read 1 Byte). 1. Can the driver read only 1 byte of data from the reader even if the reader has more data in its reply block ? 2.

    - driver performance monitoring We have WDM based USB driver and it runs fine on XP but when loaded on VISTA, when using one of the diagnostic application, my PC CPU usage hits 100%, but this application runs fine on XP. Is there a good profiling tool to monitor which exact driver rountine is running when CPU hits 100% usage. I can not trying traceview tracefmt tools because this requires code changes in the driver. trv Tag: update: WDK 6000 build.exe dependency issue Tag: 92592

    - Can mirror driver support multiple monitors I wrote a mirror driver based on Windows DDK mirror driver sample before. It runs pretty okay. But it tested only on the windows XP with singleton monitor. I installed my mirror driver on the windows XP with dual monitors or triple monitors last week. The system crashed. I got a blue screen when I tried to install the mirror driver. Sometimes, I could luckily install the mirror driver. It showed that the mirror driver was working properly. But the system crashed again when I tried to enable the mirror driver. Does Microsoft mirror driver only support the primary display? Is it possible for the mirror driver support multiple displays. If yes, How? Any comments are welcome! Thanks in advance. Lee Tag: update: WDK 6000 build.exe dependency issue Tag: 92588

    - non-admin SPTI calls on Vista: possible or not ? I am trying to clarify what is the situation with SPTI calls and Vista? 1) I've read before that Vista [presumably] allows by default non-admin SPTI calls to optical drives ... is it really so? 2) If yes, how to get device handle from the program running in standard mode? I tried CreateFile with a "device instance" name received via SetupDi* enumeration but CreateFile failed with "access denied" diagnostics. Works fine in elevated [Run as Admin] mode, though ... Any help would be greatly appreciated! Many thanks! igor. Tag: update: WDK 6000 build.exe dependency issue Tag: 92581

    - Controller enumeration question - Backward XP UINumbers. I have two hard disk controllers in a PC, and hot plug a disk drive in to controller 1 first, then the second drive into controller 2. As expected, the first drive appears in the Disk Manager as Disk 1, and the second disk as Disk 2. Now, I reboot the PC. The disks listed in the Disk Manager are now swapped. This is expected behavior according to a KB article; "Windows Server 2003 and Windows XP perform an in-place reorder operation to optimize PnP. As a result of the reorder operation, Windows Server 2003 and Windows XP may enumerate the hard disk on the secondary IDE channel before the hard disk on the primary IDE channel. The hard disk that Setup detects last is listed first." Unfortunatly, as a writer of a hard disk controller utility, it's hard to tell my users what has happened. I need to be able to present controllers in a consistent manner so they know what drive is attached in an intuitive manner. The question is, how do I get a controller numbering scheme that will "match" the disk numbers in the Disk Manager? I can't simply reverse the order (per the quote above) b/c Windows's controller enumeration scheme may change at any release of Windows (i.e., Win2K orded controller the other way). thnx.

    - Vista and NDIS 5.0, Do they play nicely together? We have an NDIS 5.0 compliant WLAN driver sitting on top of a proprietary bus driver. Vista does load the bus driver and when the bus driver enumerates the WLAN driver, Vista does install and load the WLAN driver. The only problem is that the installed WLAN driver is not recognized as a network driver. The install package works fine in Win2k and XP. We are actually "" that close to Logo on XP so the inf files and Installshield at this point should not be in question. Does Vista install and run NDIS 5.0 compliant WLAN drivers?

    - About 64 bit in bulk sample. Hi, I looked at driver sample in the DDK and in the bulkusb they seems to all point at the 32 Bit version in the INF file. Despite the fact that there is environment for 64 Bit. My question is 64 Bit operating system backward compatible with the binary of a 32 Bit WDM driver. If not, is there a sample that generates both? Thanks Denis Tag: update: WDK 6000 build.exe dependency issue Tag: 92573

    - authrootseq.txt ? Does anybody now why a DifXApi install requires network access to : http://www.download.windowsupdate.com/msdownload/update/v3/static/trustedr/en/authrootseq.txt ? We have a difxapi signed driver based installer which for some reason is unable to access the required URL. Disabling the network (and rerunning the install) allows the install to continue. Obviously if the URL is inaccessible and given the installation can run when not connected to the network, why fail completely when the URL cannot be found?

    - TUSB3200(Streaming Controller) based Audio Device Driver Hello Experts, I am trying to write a driver for TUSB3200(Streaming Controller) based Audio Device on XP. Can anybody suggest me Which sample is suitable for me from DDK kit. The TUSB3200 Controller includes both Bulk and Isochronous tranfers along with DMA channels. I found AVStream sample in DDK but I am not sure will it be a good sample for my needs. Can anybody suggest/Advice me in the right direction. Your valuable suggestions are always appreciable.

    - USB thumb drive random re-plugging ("Delayed Write Failed") I have a USB thumb drive, and I've noticed that if I have it plugged in while I plug in my USB mp3 player into a different USB port then the thumb drive's root directory will pop up in an Explorer window as if I had just unplugged and then plugged it back in again (even though I haven't touched it). I think the Plug N Play manager is actually re-enumerating it, removing and re-adding the device stack, because if I'd previously enabled write caching ("Optimize for performance" in Device Manager) and formatted it with NTFS then I'll get "Delayed Write Failed" error messages at this time. Yes, I know I can disable write caching to make the error message go away, but I think that will only make the problem less likely to happen and less likely to notice. I want the drive to work correctly, not simply fail silently. If there happened to be data transferring to the thumb drive at the moment when it disappeared and re-appeared then that data would be lost. Is this a Windows problem, USB host controller problem, or a USB device problem? Tag: update: WDK 6000 build.exe dependency issue Tag: 92556

    - Is there a limit to how large buffers can be read on 1394 I have developed a WIA driver for a 1394 device. The device is able to deliver 16 MB data chunks but it seems that there is a limit around 2MB for each call when I ask for data using DeviceIOControl. Is there such a <2MB limit? I believe it is using scsiscan.sys a the kernel driver for 1394. Tag: update: WDK 6000 build.exe dependency issue Tag: 92553

I reported this issue to the NDIS team during our weekly call with MSFT. Now
I got an ACK that the WDK team is able to reproduced in Redmond. It's being
taken care of.
