    - windows vista 1394diag I developed my driver in the line of 1394diag.sys. I want to communicate between different PCs over 1394. I can connect two Windows 2000 PCs and communicate without a problem. I can even communicate between Windows 2000 and XP. I am not able to communicate with Windows Vista PC. Neither windows 2000 nor XP recognize Windows Vista. I am using Microsoft\1394_PC in the inf file. Similarly Windows Vista is not recognizing either Windows 2000 or windows XP. What should I do to make windows XP recognize windows vista and vice versa over firewire connection? Thanks, Raj Tag: when will Microsoft release 1394b driver? Tag: 98486

    - WDM driver issue at 4GB memory Hi there, I have a WDM driver which does scatter gather DMA and works fine except for when I have 4GB memory in the system. I was wondering If someone could provide a tip as to what might be going wrong and what should I be looking for. Thanks, Markov Tag: when will Microsoft release 1394b driver? Tag: 98485

    - Could I auto-launch a push-model aware application via WIA video USD driver (wiavusd.dll)? STI provides a push model to auto launch application for some STI events. If I provide a STI USD dll, it can monitor my PC camera device and notify the STI event monitor of a user-defined event. The application will be launched if it has been registered with that event. Since Microsoft provides WIA video USD minidriver for video devices on XP or later. I hope my video device can use wiavusd.dll without providing my own USD minidriver. However, I don't know whether wiavusd.dll notify the WIA device manager any event if the camera stream class minidriver calls StreamClassDeviceNotification( SignalMultipleDeviceEvents, deviceExtension, &USBCAMD_KSEVENTSETID_VIDCAPTOSTI, KSEVENT_VIDCAPTOSTI_EXT_TRIGGER) to notifies a STI button trigger event. I want to know whether wiavusd.dll notifiy the following predefined STI events GUID_DeviceArrivedLaunch GUID_ScanImage GUID_ScanFaxImage GUID_ScanPrintImage GUID_STIUserDefined1 GUID_STIUserDefined2 GUID_STIUserDefined3 Best Regards Jack Huang Tag: when will Microsoft release 1394b driver?

    - A very weird problem on IoCompleteRequest()'s unassembled code! Hello all, IoCompleteRequest is a most frequently used routine in driver development. So I wanted to dig its implementation by unassembling with WinDBG. The unassembled code is as follows. The target machine is running on Windows XP + SP2. ================== Code Begin ================== kd> u IoCompleteRequest nt!IoCompleteRequest: 8052efc1 8bff mov edi,edi 8052efc3 55 push ebp 8052efc4 8bec mov ebp,esp 8052efc6 8a550c mov dl,[ebp+0xc] 8052efc9 8b4d08 mov ecx,[ebp+0x8] 8052efcc ff15043e5580 call dword ptr [nt!pIofCompleteRequest (80553e04)] 8052efd2 5d pop ebp 8052efd3 c20800 ret 0x8 kd> u 80553e04 nt!pIofCompleteRequest: 80553e04 95 xchg eax,ebp 80553e05 51 push ecx 80553e06 4e dec esi 80553e07 80f89c cmp al,0x9c 80553e0a 4e dec esi 80553e0b 80389c cmp byte ptr [eax],0x9c 80553e0e 4e dec esi 80553e0f 800000 add byte ptr [eax],0x0 kd> u nt!IopPostPadding+0x2: 80553e12 0000 add [eax],al 80553e14 0000 add [eax],al 80553e16 0000 add [eax],al 80553e18 0000 add [eax],al 80553e1a 0000 add [eax],al 80553e1c 0000 add [eax],al 80553e1e 0000 add [eax],al 80553e20 0000 add [eax],al ================== Code End ================== As shown above, IoCompleteRequest is implemented by pIofCompleteRequest located at 0x80553e04.

    - Can I modify the video driver to set default resolution? I want to modify the video driver to set default resolution of windows xp to 1024x768. It means that when I setup the driver and restart my computer the screen is in the resolution of 1024x768. I found most of video drivers setting the default resolution to 640x480 in windows xp. Can I do it? Thanks, Sunwill Chen Tag: when will Microsoft release 1394b driver? Tag: 98472

    - how to detect WDDM vs. XPDM How can I programmatically determine whether Windows Vista is using a WDDM driver or an XPDM driver? I can enumerate the drivers and obtain a name such as: RADEON XPRESS 200M Series (Microsoft Corporation - WDDM) but there's no guarantee that all WDDM drivers have the string "WDDM" in the name. Any other suggestions? Tag: when will Microsoft release 1394b driver? Tag: 98455

    - Need help with new submission We are submitting a driver for a modem family in 2003 Server. We are using the new DTM for the first time, going through a learning curve. So, I need to know if I am missing anything here. I am taking over for a guy that just moved to a different department. He couldn't get past this step, and neither can I. We have a customer requesting certification in 2003, so we would appreciate any help possible. If you need more information, please let me know. In Studio, I click on Explorers. I add a new pool, called SubCon1. I drag the name T1 (Studio), to the new pool. I right click on SubCon1, and set the MCU to network/Modem. I back out, right click on SubCon1 and do a reset. I hit refresh until it says ready. I click on Explorers, click Device Console, Create a new Submission, Choose Windows 2003 <next>, In the Catergory, choose Device Submission <next>., In Logo Program, choose Network/ Modem <next>, Qualification Level, choose Basic (only option), <next> and get the error "The configuration jobs required to set up the selected machine pool have not finished". We followed KB article 934533 several times, and still get the same result. Kraig Tag: when will Microsoft release 1394b driver? Tag: 98448

    - CreateService/DeleteService not doing their jobs ... Hi , I have question on CreateService/DeleteService. >>The CreateService function creates a service object and installs it in the service control manager database by creating a key with the same name as the service under the following registry key: >>HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services The above line yanked out of CreateService() page, says a entry is made in the registry when the driver gets loaded. >> The service control manager deletes the service by deleting the service key and its subkeys from the registry. The above line yanked out of DeleteService() page says that it will delete the Registry entry. But the fact is I donâ??t see the removal part of it. I run only instance of the application and load only one driver and then unload. I do all the procedures needed correctly to remove the service because I am using one of your DDK examples without modifications. Ex: If I run my application from say c:\abcd\app once it works fine. Assume I copied the app+driver to say e:\xyz\app and deleted it form c:\abcd\app. Then it will not run. It will complain the Driver is not in the directory expected. If I copy the driver back to c:\abcd\app and then run the app from e:\xyz\app it will work. Even after a reboot the registry entry does not get deletedâ?¦ Please explain why this deletion never happens? What is the solution? OS: W2K3, SP2, x64 bit. However I have seen this happen on other OS and x86 also. Thanks for your time and advice Best regards, Ananda vardhana Tag: when will Microsoft release 1394b driver? Tag: 98446

    - Disk geometry Hello, I want to obtain the disk geometry and need help with an error I am seeing. The code snippet is as follows: RtlInitUnicodeString ( &uName, L"\\Device\\Harddisk1\\DR2" ); dStatus = IoGetDeviceObjectPointer ( &uName, FILE_ALL_ACCESS, &pFileObject, &pDeviceObject ); .......... irp = IoBuildDeviceIoControlRequest ( IOCTL_DISK_GET_DRIVE_GEOMETRY_EX, pDeviceObject, NULL, 0, (PVOID)pOutputBuffer, *pdOutputBufferSize, FALSE, &event, &IoStatus ); if (!irp) { return STATUS_INSUFFICIENT_RESOURCES; } status = IoCallDriver (pDeviceObject, irp); The IoCallDriver returns NT_SUCCESS but the disk geometry (pOutputBuffer) is all zero's. What am I missing? I tried RtlInitUnicodeString ( &uName, L"\\\\.\ \PhysicalDrive0" ) but got the same result. Thanks, ..Ram Tag: when will Microsoft release 1394b driver? Tag: 98437

    - WdfRequesSend causes WDF access violation I am rewriting a WDM driver to use KMDF. My driver forwards most requests to the system supplied serial driver used as lower filter driver. The requests are forwarded using WdfRequestSend with the WDF_REQUEST_SEND_OPTION_SEND_AND_FORGET option. This completes successfully, but after my event handler exits an access violation (c0000005) occurs at Wdf01000!FxIFR+0x111. No doubt I am doing something wrong, but I don't see how to find out what. Any ideas?

    - Mirror driver, screen-to-screen BitBlt and consistency. Hi everyone. I'm trying to develop mirror video driver for VNC-like aplication. I've made a "stupid" version that just shares framebuffer into user- space and provide another buffer to store screen updates (just a bounding rect of a CLIPOBJ). But such a driver "produces" too much traffic. It is not much less than while using "blit-and-XOR" approach (BitBlt from screen, XOR with the previous frame and send the result over a wire) in most cases. So, I decided to implement a kind of updates z-Buffer, so that you can discard previous update if it was covered by another one the next moment. But it is not the case in point. The second way of bandwidth utilization improvement is taking screen- to-screen BitBlts into account. They often happen when scrolling appears. When screen-to-screen BitBlt occurs we need to send just a notification with the two rects coordinates instead of the whole bitmap, so this approach can decrease network traffic significally. But there is one problem. If screen-2-screen BitBlt occurs while user- mode application reads frame buffer, data sent to the other client might be inconsistent. And this inconsistency won't be fixed when "screen-to-screen" command is sent because this command carries no bitmap data, and data on the other side of the wire is taken from it's local screen copy which is corrupted. I see two ways of resolving this problem. First is to refuse the idea of taking screen-to-screen BitBlt into account and treat them as a bitmap-to-screen. The second way is to refuse the idea of grabbing the image directly from the framebuffer and create a separate bitmap for each BitBlt and share it's bits into userspace. Please tell me what approach is preferable. I tried to figure it out by disassembling Microsoft's rdpdd.dll, but it's to complex and has many obscure things like additional parameters cheks in DrvXxx berfore calling the corresponding EngXxx and use of private data structures.

    - Digitally signed drivers Hi, For installing a drivers which are signed with SPC certificates, on Vista64: 1) Do we need to ask users/clients to install the certificate on target machine? 2) I have a certificate from Verisign. To which certificate stores should the users install the certificates on target machine? 3) Is there a way to install certificates on target/client machines without user requiring to do it manually? Thanks. Tag: when will Microsoft release 1394b driver? Tag: 98415

    - Filter Centric AVStream driver stops receiveing Process dispach ca I have an AVStream driver I wrote for a card that my company makes, which follows the filter centric model. I also have down stream DirectShow transform filters that interface to the driver through the KSProxy. In general things work pretty good, but when I allow my system to run continuosly for long periods of time (meaning 24-48 hours), my device driver will stop receiving Process dispatch calls from Windows. The down stream transofrm filter is waiting for samples from the driver through the proxy, and the driver is waiting for a Process call from the Windows, the card is waiting for the driver to empty data out of it's full buffers, and the whole system just stops running. Does anyone have any idea what inside Windows causes could cause the Process dispatch to stop being called? Tag: when will Microsoft release 1394b driver? Tag: 98411

    - how to get the status of threads related to a driver Hi everyone, I am a new hand for driver devlopment. Now I face with a problem. I want to view the status of threads related to a driver. For example, are threads related to usbvideo driver runing or suspending (waiting for events). These information is very inportant for me to judge whether the thread related to driver occupy the cpu or not. Is there any way to make it possible? Does windbg provide the command to view it?

    - WinDbg & kernel-mode debugging of virtual machines Are there any good white papers or other discussions about setting up WinDbg for kernel-mode debugging of a driver within a virtual machine hosted within VMware Workstation? I'm getting started on some file system filter driver and/or file system minifilter driver development. I have a build environment set up on Vista Ultimate x64, and have a variety of VM guests for WinXP Pro SP2 x86, Vista Business x86 & x64, and Win2K3 R2 x86 & x64. My intent was to use these VMs as my test environment instead of having a separate physical computer with multiple bootable partitions, etc.... Since kernel-mode debugging with WinDbg involves having a COM port or FireWire connection between the debug host & the test system, I was looking for some sort of virtual COM port that I could run under Vista that would connect up to the named pipe that VMware Workstation can associate with a COM port inside of a VM guest. Does such a thing exist? Is anybody else successfully doing kernel-mode debugging of a driver on Windows running as a VMware guest?

    - KMDF Buffered vs Direct IO I have a KMDF driver that sets the IO type to Direct and uses WdfRequestRetrieve(Output/Input)Buffer call inside EvtIoRead/EvtIoWrite to get a pointer to the request buffer. This works fine. However, if I switch the device IO type to Buffered, then the WdfRequestRetrieveX functions return SUCCESS status, yet set the buffer pointer to NULL. I don't see any explanation for this in the documentation, as these functions are supposed to work identically regardless for both Direct and Buffered IO type; furthermore, I imagine that a buffer retrieval problem would be indicated by the returned status. Any ideas? Tag: when will Microsoft release 1394b driver? Tag: 98391

This works fine unless I have a printer (anything, 'Generic / Text only', the printer itself) setup to use LPT1 in windows.

    - BSOD in usbuhci Hi Guys, I need your help in debugging a BSOD in usbuhci. Our device sits on uhci controller, has two bulk endpoints - in and out. When application starts streaming I submit 10 bulk in request to the controller, when the request is completed data is copied into user buffer and request (irp/urb/data buffer) is re-sent to the controller. From time to time (once in few seconds) I submit bulk out request. Now the problem: the BSOD I get appears once in a month, at this rate it is very hard to understand under what conditions it occurs. Here is crash dump analysis, hope you'd help me to figure this out. Does the crash happen with bulk in or bulk out request? The bulk in buffers are allocated in system memory, bulk out buffer is a user buffer which is locked and mapped. So what is the problem?

    - When and how does KeDelayExecutionThread get alerted? Hi all, The DDK documetation says: "If the value of Alertable is TRUE and one of the following conditions is present, the thread will be alerted: 1, If the origin of the alert is an internal, undocumented kernel-mode routine used to alert threads. 2, The origin of the alert is a user-mode APC, and the value of the WaitMode parameter is UserMode. In the first of these two cases, the thread's wait is satisfied with a completion status of STATUS_ALERTED; in the second case, it is satisfied with a completion status of STATUS_USER_APC." However, the parameters passed into KeDelayExecutionThread doesn't include any dispatcher object such as event, semaphore, mutex, etc. My question is: By which dispatcher object does current sleeping thread get alerted? Except by user APC. Thanks in advance. Tag: when will Microsoft release 1394b driver? Tag: 98358

The problem is that when I connected my digital camera, there was a message telling me that the connection would be faster if I had USB 2 Another telltale sign that sth is wrong is that films played on my external drive block (presumably cos the info can't arrive quicly enough) So why doesn't XP recognise a USB 2 card? Anyway, I tried to download a USB 2 driver for Windows and found the Intel Desktop Driver for XP However, on a manual install, XP refuses saying that a more suitable driver is already installed. In system, this drivers seems to be a Microsoft Driver version 5. 1 2600 released 01 June 2002 Is this a USB 2 driver? Hope sm out there can help me. Thanks in advance Dave Neve Tag: when will Microsoft release 1394b driver? Tag: 98308

    - IWiaItemExtras::Escape and VendorReadData? Greetings, I am trying to work with WIA, and I have found the IWiaItemExtras::Escape function. Which can be used to interact with vendor specific commands. But while I use the command I can get the 1st letter specified from the command, but how do I get the acutal data from VendorReadData? It always has 1 byte of data, and I am not sure where to get the output buffer. For example: PTP_VENDOR_DATA_OUT* pDataOut; HRESULT hr = spExtraProps->Escape(ESCAPE_PTP_VENDOR_COMMAND, (BYTE *) pDataIn, dwDataInSize, (BYTE *) pDataOut, dwDataOutSize, &dwActualDataOutSize); When I access the "pData->VendorReadData" it is always the byte[1] size, so I am not sure how to get the actual data. Thanks for any suggestions! Tag: when will Microsoft release 1394b driver? Tag: 98306

    - HID mini port over i8042prt PS2 stack? I'd like to report my PS2 interface device to system as a HID class device. That means I'd like to ask i8042prt to be my port driver, I know there is a moufilter sample in the DDK, well it report itself as a mouse class instead of HID class, and it is a upper filter for the i8042prt. Is it possible to create a HID driver which talked to i8042prt and report itself as a HID class device? Any hint would be apprecited. -chueh888 Tag: when will Microsoft release 1394b driver?

    - How to hide system error messages. Hi, I am writing a file system minifilter driver. When I fail the create file operation from preoperation callback routine, a windows error message pops up saying "file is not a valid win32 application". and it restricts file from opening successfully. But I want that no popup should be displayed on successfully blocking a file. How can I hide this system popup? Can anybody help me?

    - Why and how is the module name of ntoskrnl.exe displayed as "nt" rather than "ntoskrnl"? Hi experts, I find a weird problem with the WinDBG command 'lm n t': kd> lm n t start end module name 7c920000 7c9b4000 ntdll ntdll.dll Tue Aug 17 07:38:36 2004 (4121457C) 804d8000 806ec600 nt ntoskrnl.exe Wed Aug 04 14:19:48 2004 (41108004) 806ed000 80700d80 hal halacpi.dll Wed Aug 04 13:59:04 2004 (41107B28) bf800000 bf9c0200 win32k win32k.sys Wed Aug 04 14:17:30 2004 (41107F7A) bf9c1000 bf9d2580 dxg dxg.sys Wed Aug 04 14:00:51 2004 (41107B93) ..... All of the module names except 'nt' are their image name without extention. Why? I also wonder how the debugger determines the module name of a given kernel module? Any help will be highly appreciated. Thanks in advance. Tag: when will Microsoft release 1394b driver? Tag: 98282

when will Microsoft release 1394b driver?
Will the new 1394b driver be available on Windows XP ?
Will 1394b driver be fully compatible with present drivers?

I hope there is a place to post the concerns of special drivers like
firewire and USB.

Thanks,

Current plan is to release with the next version of Windows
(http://en.wikipedia.org/wiki/Windows_%22Vienna%22). If you want 1394b
support on Vista and downlevel, you should contact MS tech support and make
a bussiness case with them.
