    - Creating Keyboardlayout in Windows Ce 4.2 We are using Platform Builder 4.2. We created il.cpp and dl.cpp files which were used kbdgen.exe tool. And then we created kbd..dll with EVC++4.0. We put this .dll file in to release directory and define the Layout File, Layout Text and PS2_AT values [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Layouts\0000041f] "Layout File"="Input Language DLL name goes here" "Layout Text"="Input Locale description goes here" "PS2_AT"="Device Layout DLL name goes here" HKEY_CURRENT_USER\Keyboard Layout\Preload\1] @="0000041f" then rebuild platform but unfortunately new keyboard was not recognized.

    - crash in directx when usb hid device is connected Hi all, I have developed a USB HID device based on the PIC16c745 - it works great, but there is one small problem. When it is plugged in, most directx apps (eg. games and dxdiag) crash inside of dinput.dll. Other than this, the devices works great, I can control it via the HID interfaces in the DDK without any problems. When the crash happens the backtrace looks like this: http://www.heenan.me.uk/vs.png Without this USB device that I have developed connected everything works fine. I'm using the latest available version of directx (Feb 2006) on XP Pro. Same version on Server 2000 does not show the problem. I initially posted this into the programmer.directx.input group (see http://tinyurl.com/z5zkb) but they suggested I post here instead. Any help greatly appreciated.

    - question for secondary dump data callback Hello. I have problems with my bugcheck secondary callback (WinXP SP2). My callback is indeed called, but there are two issues: a) My callback is called only once, and I cannot see my information in the kernel crash dump. I believe that the DDK mentions that my callback should be called twice: once for buffer length and address acquisition, and then again for actually copying the data. My callback code, which was adapted from an archive, is shown below after this letter. b) In some cases, when I tried the .enumtag command, I got a listing of information (my GUID was not there). However, sometimes I got the following error: 1: kd> .enumtag Unable to start enumeration, HRESULT 0x80004002 (E_NOINTERFACE, what does it mean here, and did I cause it?) Any ideas? thanks, Philip Lukidis bugcheck callback: // watch out, called at IRQL==HIGH_LEVEL VOID TestBugCheckSecondaryDumpDataCallback( IN KBUGCHECK_CALLBACK_REASON Reason, IN PKBUGCHECK_REASON_CALLBACK_RECORD Record, IN OUT PVOID ReasonSpecificData, IN ULONG ReasonSpecificDataLength ) { UNREFERENCED_PARAMETER(Reason); UNREFERENCED_PARAMETER(Record); PKBUGCHECK_SECONDARY_DUMP_DATA pData; pData = (PKBUGCHECK_SECONDARY_DUMP_DATA) ReasonSpecificData; if(pData && (ReasonSpecificDataLength==sizeof(KBUGCHECK_SECONDARY_DUMP_DATA))) { pData->Guid = TEST_CRASH_GUID; // this is for acquiring the address and buffer length if(pData->OutBuffer == NULL) { pData->OutBuffer = (PVOID)g_CRASH_STRING; pData->OutBufferLength = g_CrashLen; } // request to copy the data (we never get here, we're called only once!) if((pData->InBuffer == pData->OutBuffer) && pData->InBuffer) { if(g_CrashLen < pData->OutBufferLength) { RtlCopyMemory(pData->OutBuffer,g_CRASH_STRING,g_CrashLen); pData->OutBufferLength = g_CrashLen; } } } } Tag: output queue length Tag: 76943

    - RAID Cluster MAP to Physical LBA relationship Does anyone know of any tools which display the current mapping between clusters and physical LBAâ??s on an XP Pro (SP2) NTFS (three drives) Stripe set and is there any method of changing this? Maybe a description of how NTFS is implemented across a RAID array? I have a video application simulated by writing a 100MB file and reading the file back. The file is written to 3x SCSI disks, striped and formatted using NTFS (default cluster size of 4KB). The system is a 3.6GHz Xeon with 3.25GB RAM. The simulation creates multiple files (keeps going until the volume is full) and for each 100MB file calculates the average write transfer rate and read transfer rate. Most of the time, the write transfer rate is around 160MB/s but sometimes drops to 75MB/s (occasionally much less). For writes, a dip to 120MB/s for the real application could cause a loss of some real-time data. Concentrating on Writes: with the higher transfer speeds, each of the 3 drives in the Stripe get Write commands to the same LBA and (mainly) 64K transfers. The LBAs being written to are sequentially increasing. For the â??badâ?? scores a combination of things can happen. The LBAs being written to will increase sequentially and then the LBA range will change (usually lower physical area of the disks) and/or the transfer size will change to much less than 64K (I saw one transfer of 4K). The change of LBA range wouldnâ??t hurt things much, but the change in transfer size from 64K means much less efficient use of the SCSI bus (more commands, less data with each) and seems to be the root cause of the occasional performance dip. The issue does not appear to be anything to do with fragmentation â?? just the way in which the drives are being used by XP / NTFS Hence the question - Any good tools to look at how a files is going to be mapped physically on an NTFS Software RAIDed volume - Any method of tweaking? NOTE: This is the fisrt time I've used the forums so apologies if this is the wrong forum to be asking this question! Tag: output queue length Tag: 76941

    - Occasionally false samples from a soundcard driver A PCI bus based "professional" soundcard has a digital input (S/PDIF). Connected this input to a CD player's output and recorded about 20 seconds using waverecorder. Found 12 "clicks" in the recorded WAV file. The clicks are false sample values, exactly one false sample in each case (sample rate does not matter, same at 22kHz, 44.1kHz, 48 kHz, 96 kHz). Sample value is random (never full scale nor zero). Searched for the clicks and determined their sample number. 10 of them have a sample number ending with "1", 2 of them end with "2", so definitely *not random*. Calculated the difference between sample numbers ending with "1". Calculated the gcd (greatest common divisor) of these differences and found that it is always 440 (or multiples of 440, e.g. 880, 2200). Soundcard is a PCI busmaster, but has "Min_Gnt = 0" and "Max_Lat = 0". My questions: From the point of view of a device driver programmer do you have any idea what goes wrong here? What may the 440 stand for? Juergen Tag: output queue length Tag: 76933

    - Returning order of CompletionRoutines() and IoCallDriver() Hi Let's say I'm a high level driver and i call IoCallDriver to pass an IRP down the stack, and the whole operation is synchronous. There are several devices in the stack (let's say A,B,C,D), each one of them has a completion routine (except D). After device D completes the irp, all completion routines for all the devices are being called, and only afterwards all the IoCallDriver() routines of all the devices return?

    - IoCompleteRequest() from WorkItem Hi Lets say I'm in PASSIVE IRQL in a dispatch function. I mark my irp as pending. Later, I create a workitem that receives the irp as a context and do some work in it. In the end of the workitem's function, I complete the IRP. Back to the dispatch routine - after allocating and queuing the workitem, I return STATUS_PENDING. Now, because I'm in PASSIVE level, there can be a context switch from my dispatch routine to my workitem's function, so it will run and complete the irp, before I return STATUS_PENDING from the dispatch routine. (it means that when I return STATUS_PENDING, the irp is already completed!) Is there a problem with the above scenario? And if so, how should I handle it? Tag: output queue length Tag: 76904

    - PICs for driver signing in x64 unavailable? I was just forwarded an email response we received from WinQual when we inquired about getting a PIC for signing our drivers for the new x64 signing policy. I'm hoping I'm just over reacting, but... I was disturbed to hear that they are not available at this time. In fact, there was a strong implication in this email that PICs would not be available until the last release candidate for Vista. Here is the relevant portion of this email: "This is not available yet, but should be in time for Vista launch. The PIC is a new signing program for files we couldn?t sign before. We?ll be making more announcements regarding the availability of PIC to sign drivers as we get closer to the Vista logo program launch, which will be at the last Release Candidate." Microsoft has done this in the past (i.e. not releasing full WHQL tests, signing tools, etc. until just before RTM), and it always has caused problems. So I'm trying to head this off at the pass this time. I don't know about the rest of you, but we need time to get a PIC, integrate signing with it into our build process, build a driver, test it internally, fix any problems that signing caused (and rebuild and retest) and deliver a candidate driver to the OEMs early enough that they have time to test it themselves (and get any needed bug fixes) before their deadline for burning a golden master for manufacturing of their first x64 machines. And that's assuming that the Vista Beta community doesn't find any bugs in the kernel embedded signing code in Windows... I'm crossposting this to m.p.d.d.d because I think this issue is of wider interest than just the winlogo newsgroup. And yes, I've already sent an email to WinQual about this. -- Ray Tag: output queue length Tag: 76867

    - unidrv plugins and dialog boxes I have been having difficulty trying to determine where it is possible to display a dialog box from a unidrv plug-in. From what I read in the documentation it appears as though both UI and rendering plugins run in the application's context, before anything is sent to the spooler. If this is indeed the case I would assume that it would be possible to display a dialog box to capture document specific properties during EnablePDEV processing in a rendering plug-in. This would allow me to capture things like fax #s for each document by displaying a dialog to the user who started the job. I further assume that the dialog box would appear in a particular user's termnal services window. Are my assumptions correct or am I completely out to lunch? If I am out to lunch what would be the easiest way to capture fax #s for each individual document in a terminal services environment? Tag: output queue length Tag: 76853

    - Word crashes with my printer driver, but no other programs do. Hi, I'm developing a printer driver UI based on the MSPLOTUI sample from the DDK. It works great from all applications except Word, which craches. It seems that Word is calling some functions on the driver that the other programs don't. Can anyone give me a list of the printer driver functions that Word calls, and the order they are called? /Erik Tag: output queue length Tag: 76851

    - Large Transfer Lengths With SCSI Pass-Through? Is it possible to make transfer larger then 64KB via SCSI Pass-Through? If so how is the best way to go about it? If this is SCSI HBA dependent how can you tell the maximum transfer length size allowed? I looking to test up to 16MB transfers. Tag: output queue length Tag: 76849

    - Write a WDM driver Hi, I wanted to write a Mouse filter driver which will intercept the mouse click and trigger the user applications like those in the logitech , but not their own.. i wanted to invoke my own applicatoins. I have tried to write the mouse driver but got stuck.. I am stuck at this point as what approach I should take? If I should take the HID class help or what ... ? I have fair understanding of the WDM but not done any fillter drivers... I want to the driver on the machines and configure the mouse to open my application intercepting the mouse clicks.. I would really appreciate if anybody gives me the proper direction on designing the driver.. thanks. -- Abhijit. Tag: output queue length Tag: 76848

    - installing a driver using devcon hello, i have a weird behavior i don't understand - i'm using devcon in order to install a software driver. when i put the sys and inf file in any folder (even hidden) everything is ok, but when i put them in the c:\windows\inf file there is a pop up asking for the sys file (and when i direct it to the inf folder it installs it). why is that? how do i solve that? thank you, Tag: output queue length Tag: 76847

    - Causes of USBD_STATUS_ISO_NOT_ACCESSED_BY_HW Greetings, I realize in my previous post "NEC B1 HC chokes with full BW USB2 ISO IN stream" my primary question was hidden in a flurry of details. Can I be doing something in my USB camera driver to cause the USBD_STATUS_ISO_NOT_ACCESSED_BY_HW error I am seeing with the NEC host controller? The only thing I have heard of that causes this error is URB starvation. That is clearly not the trouble. I am queuing 10 URBs of 32 packets each. Also, the driver works perfeftly under the VIA controller. Is there some subtle error I might be causing that effects the NEC controller but not the VIA one, or is there simply a bug in the NEC controller?

    - WDF Driver Install problem Hi, I'm developing a WDF driver for a PCI device. I have written a simple driver and the INF. The INF file seems ok when used with CHKINF. When i install it on the target system (XP checked build 2600) everything looks ok but at the end it simply says the drivers are not installed. Looking in WinDBG reveals the following when the driver installs: InstallDev error = 643 Anyone have any suggestions? Have tried to find information on the error but am having trouble finding anything. Thanks in advance. Tag: output queue length Tag: 76844

When I put my NIC card under load, I see the output queue length in
perfmon go up and down. However when I stop the traffic, this count
never goes to zero. Is this a problem?

Surely it is. Can be because of the sync problem you described in your
previous post.
