    - HID implementation on Windows XP/Longhorn We're putting together an ASIC that exposes HID as well as non-HID devices on the same chip, with one USB device port. That is, there's one device, several endpoints, several configurations. My question is.. Is it better to put these devices behind a hub, or to just expose the multiple endpoints without a hub? We're still in the hardware design phase, so we can go either way I had read somewhere that there are issues with using the stock Microsoft HID driver if there are other endpoints peered to it. Any and all comments are appreciated Thanks in advance! Tag: How to let FAT and FAT32 available only, for Formatting SD in windows XP Tag: 45923

    - USBCAMD2 Video Freeze issue. Hi all, I'm having a stange problem with a USBCAMD2 based driver for a custom USB camera we're working on. We have only 1 video stream whose format is RGB24. In ProcessRawVideoFrameEx(), if I do the following: frameBuffer = (BYTE*)FrameBuffer; frameBuffer[0] = frameBuffer[1] = frameBuffer[2] = 0; . . fill in the rest of the frame buffer with actual data . the video frame is not drawn. However, if frameBuffer[0], frameBuffer[1], or frameBuffer[2] is non-zero, the video frame is drawn (Note that only one needs to be non-zero, not all three). We noticed this because the video stream would "freeze" whenever the first pixel was completely black RGB(0,0,0). As soon as the pixel goes to anything but black, the video resumes. Has anyone else seen this? I find it quite bizarre & can't figure out why it's doing it. Thanks, Jerry Tag: How to let FAT and FAT32 available only, for Formatting SD in windows XP Tag: 45920

    - memory mapped files I'm loading a large file into a section with ZwCreateSection. Then I'm going to map a view with ZwMapViewOfSection I only need a portion of this file to be visible in my View. But the portion starts say at offset X into the file. I only need to read Y bytes of the file from that point on. Are the SectionOffset and ViewSize arguments for ZwMapViewOfSection the right guys for this job If X is not an even multiple of the PAGE_SIZE, then where is the rounding down reflected so that I am aware of what the Base Address is actually pointing at. Is it pointing to the 0th byte of my view, i.e the Xth byte of my file or are other offsets involved Please fix this picture for me Virtual Memory p == page boundr ( ==start of my file after its mapped int ) == end of my fil X == start of where I'm intereste Y == length in bytes of what I'm intereseted i ] == end of where I'm intereste p-------....--------p--------...----------p-------------------p---------...-------p------- ... (------...-----------------X----...-Ybytes-.....-----]------...------ I don't want to end up wasting LOTS of space in the VM system and lots of time loading up the system with data I'm not interested in Thanks Tag: How to let FAT and FAT32 available only, for Formatting SD in windows XP Tag: 45908

    - User-mode midi-driver Hi everyone, I'm not sure if this is the right place to ask for, but I will just go ahead: I'm currently writing a virtual midi-driver which is implemented in a user-mode-driver mymidi.drv. I have taken the sample from the nt 4.0 ddk and adapted it to my needs. I got two problems: 1.) If I install on a system where no midi-driver has been installed previously, my driver will not show up in the audio & midi settings in the control-panel. I think that I need to install some MS component which will not exist until the first midi-driver is installed... Any hints, on what I need to include in my inf-file? 2.) If I get this thing installed right (on a system which already got a midi-port active), the driver is installed. Unfortunately there, the audio & midi settings control panel applet won't start any more. With OutputDebugString I found out, that my driver is loaded and the DriverProc is called with "DRV_LOAD" - but that's it... Does anyone have ideas why driver-loading seems to fail (even so bad that the control panel applets aborts)?

    - Auto-Reconnecting USB-Stick after DEVCON DISABLE.. - How To ? Hi everyone, have to use a USB memory stick on a w2k workstation - without a mouse! --- 1st question: Is there a way to simulate the click on that tray icon? E.g. with a startmenu entry, accessible with some keystrokes? --- 2nd question: I fooled around with DEVCON and now I'm able to "disconnect" an "enable" the drive manually with two BAT files. But after that disabling, unplugging and replugging, the drive will not be enabled automatically as it does after removing it with a click on that tray icon. Instead, I have to enable it also maually... What is different between the tray icon and DEVCON? The documentation for both is too poor, imho.

    - USB printer status, PJLMON and UI application. Hi Friends, Recently I have been assaigned the task to write a program to check the status of a 3rd party USB printer before issuing a print job. The application should find all the statuses like printer ofline, out of paper, paper jam etc.,. The vendor is not installing Language Monitor dll during installation. When I did some research I found that we have to use PJL language and a Language monitor. I also found that the printer we are targeting supports PJL and Microsoft provides a sample PJLMON Language monitor in DDK. Following is the mechanism I want to use to achieve this goal: Modify the PJLMON sample and install on the machine by modifying the printer vendor supplied .INF file. In PJLMON sample add logic to notify a UI application about the status changes( really I don't know whether using Named pipes will work here, But I will try Named pipes.) The UI application will listen for the status changes and update UI accordingly. Is this logic going to work? Am I going in a right direction? someone please help me. Please direct me to some useful resources , books or samples. I appreciate you all for taking some time to read this message . Thanks, Jagadish.

    - Disappearing Symbolic link and device Objects I have driver pair X and Y. Both are installed as a Demand Start sevices by a console app. Upon load, Driver X creates a link \\??\\Driver_X for user mode access and loads driver Y (using ZwLoadDriver). The symbolic link creted by drive X ( \\??\\Driver_X ) mysteriously disappears if I unload driver Y using the console app ( it calls service control manager StopService). The user mode apps fails to open X, obviously becuase it couldnt see the link. I verified the disappearence of the link with the sysinternals winobj. But I see the existance of the link with Osr's objdir!!! Is there any explnation why this happens? I am sure that neither the Device object nor symbolic link created by Driver X are explicitly deleted by Driver X( X never calls IoDeleteDevice or IoDeleteSymbolicLink in this case). This doesnt happen if I load X ( which in trun loads Y). Reboot the machine then try unload X using the same console app. I am running Windows 2000. This happens in only one machine, another 20 or so machines ok. -Sen Thanks, Sen Tag: How to let FAT and FAT32 available only, for Formatting SD in windows XP Tag: 45844

    - Interdriver communication page fault hi, i am a novice at drivers and need some help .. some days back i posted a query regarding mechanisms for interdriver communication among drivers not on the same stack. One of the mechanisms told was to build an IRP using IoBuildDeviceIoControlRequest() and send using the IoCallDriver() method. I allocated the buffers and built an IRP using the IRP_MJ_INTERNAL_DEVICE_CONTROL ioctl and sent it via IoCallDriver. I did it in the Passthru IM driver's MPSend() function. The idea is to route the incomming and outgoing packets' data to the TargetDriver for processing. I put the breakpoint on the SourceDriver's function in SoftICe. Now this scheme works fine once or twice when the function is called but after that there is a PAGE FAULT and everyting crashes. I thought i could get some advice on this forum regarding this. Can anybody help me with any suggestions regarding what i may be doing wrong ??? when i see the stack in the SOftIce the top most function in the stack is IoBuildDeviceIoControlRequest() .... ?? i am posting the code for the source driver(passthru)'s function and the corresponding handler in the target driver below int SourceDriver::ProcessPacket( ...

    - Buffered or Direct I am writing a driver that will need to receive a pointer to a physical address to be used for DMA from another device (not the one controlled by my driver). I have control over the interface between the two devices. I wish to pass a small structure to the "other" device in the output buffer of an IOCTL call. One fo the fields in this structure will be used to pass a physical address. My first assumption is that physical (or "logical") addresses are safe to pass from one device to another. Should I pass the aforementioned structure to the second device using direct or bufferd IO? Performance is my main objective, since the actual data transfer between the devices will be relatively small will the buffered technique actually be more efficient Brian Tag: How to let FAT and FAT32 available only, for Formatting SD in windows XP Tag: 45743

    - Miniport question Ok, I have question ... when do miniport drivers get unloaded by the system and what is the mechanism for doing that? Also, how does a video miniport differ from the more general miniports? What I'm seeing is ... that the video miniport never exits. When I remove the device the miniport is still active, when I insert the device another instance of the miniport (i think) is getting loaded. How do I cause the video miniport to exit?

    - filter above serial waits for special char hello everyone, have installed an upper filter above serial and want to let it listen fo= r = a special character. this char will be send from a device to the com-port, where my filter is= = attached on. in detail: from an usermode app. a deviceIoControl - request is send to my filter.= the dispatch-routine for this ioctl-request sends a char to the com-port= = via self-made irp (IoBuildAsynchronousFsdRequest, IoSetCompletionRoutine= , = IoCallDriver)... that works fine so far. but, after that i need to listen for an answer from the connected device= , = which is a special character. after this char is identified, a next writ= e = with some buffer content has to start immediately. my first idea was to set up a workerthread right after the write, which = = sends a synchronous read request down to serial and waits. then, the = thread validates the content of the readbuffer and initiates the next = write-op. my question is, is this a realistic method? (this is my first experience= = in driver programming) and, can such a construction react fast enough, that the delay btw. = incoming answer and next write is physicaly below 6 ms ? thanks for your answers Tag: How to let FAT and FAT32 available only, for Formatting SD in windows XP Tag: 45732

    - VfW capture driver DLL doubts Hi, I am writing a VfW capture driver DLL(user-mode). But I am facing some problems in giving the data back to the client from the driver. I am using client as WME. I have followed the steps given in the NT4.0 DDK also the sample. The driver loading, opening, closing, adding buffer's are happening properly. The client is adding a new buffer after filling and giving old buffer(which it has given before) back to the client by doing a callback from the DLL. I am setting the dwFlag header as lpVideoHdr->dwFlags |= VHDR_DONE; Actually the driver should convert the H.261 data to uncompressed video samples. But in order to ensure that driver is giving data properly to the client, I want to give some static image. I am filling the lpData member like the following. memset(lpVideoHdr->lpData, (UCHAR)255, lpVideoHdr->dwBufferLength); lpVideoHdr->dwBytesUsed = lpVideoHdr->dwBufferLength; And by using DriverCallback function I am giving the buffer to client. But client is displaying the data as "black" always. When I click encoding it is creating a new file but without any data. I am very much new to video programming. I am doing something wrong. Please anybody can advice/help to correct me. I have only done audio related applications which all are standard exe's. Also is there anyway, I can use DirectX / VCM functions to convert H.261 video data to RGB/YUV format? or Do I have to go for some open source code? It would really help me if anybody can advice or give me some hints for the above. Thanks, Sreeram. Tag: How to let FAT and FAT32 available only, for Formatting SD in windows XP Tag: 45721

    - Problem with Microsoft Bluetooth and socket accept Hi all I have successfully developed an application with the MS API. Now I want to develop a server app so I´ve basically used a complete test project found at http://www.lenholgate.com/archives/000206.html. My problem is that the application hangs on accept. I try to connect to the server from an authenticated device (Sony Ericsson Phone) and the Phone finds the computer but no services (there should be an obex service) and it is not possible to connect. I have tried both the MS and TDK dongles and both work fine from within Windows and with socket connect but not with this accept approach.

    - Common Buffer based Bus Master DMA. Hi I am working on a WMD driver for a device that supports BUS master DMA but not scatter gather. I am trying to use a common buffer for DMA transfer. I am using a buffer of about 250 Kbyte, and never seem to have problems allocating it. I'm a bit concerned about map registers. The DDK docs say: "The requested size for the buffer, shown in Figure 3.12 as LengthForBuffer, determines how many map registers must be used to provide a virtual-to-logical mapping for the common buffer. At most, the number of map registers can be the value of (BYTES_TO_PAGES (LengthForBuffer)). This value cannot be greater than the NumberOfMapRegisters returned by IoGetDmaAdapter. For more information about system-supplied macros, such as BYTES_TO_PAGES, that drivers can use, see the Kernel-Mode Driver Reference." On my machine IoGetDmaAdapter returns 2. Does this mean that I can only transfer up to 2 pages of memory at one go (ie 2*4K on my machine). Unfortunately neither the DDK or the Walter Oney book seem to cover this topic well. At the moment I just ignore the number of map registers and assume it will be OK. Half way through the PCI board transferring data from its self to the PCI address returned by AllocateCommonBuffer it bug checks. Is this likely to be because it ran out of MapRegisters? If so how can I go about transferring larger amounts of data under the control of the PCI card (or the DSP on it). I currently have a synchronisation scheme between the PC and the DSP using PIO (which sets up and controls the DMA) and I do not want to have to change this (ie I don't want to use Packet based transfer). If it comes to It I would rather send multiple buffer locations to the DSP using PIO and program the DSP to do a "scatter gather type operation".

    - modem.sys and device path exerciser We've got a problem with our modem stack running under device path exerciser from HCT suite, under XP. Occasionally, IRPs get stuck in MODEM.SYS queue. Those IRPs are originated from DeviceIoControl, code 0x002B0018, which is some private MODEM.SYS IOCTL. Modem.sys converts those to IRP_MJ_READ or IRP_MJ_WRITE and sends further to the lower driver. Our driver (acfva) is a filter which sits below modem.sys. Here is how the stuck IRP looks like: 0: kd> !irp 0x8257ae00 1 Irp is active with 11 stacks 11 is current (= 0x8257afd8) No Mdl System buffer = ff73b588 Thread 819ea020: Irp stack trace.

The completion routine is UniStopReceiveComplete, which got called. On the disassembly, one can see that this completion routine has the great potential to screw things up: Modem!UniStopReceiveComplete: f880f520 8b442404 mov eax,[esp+0x4] f880f524 8b4028 mov eax,[eax+0x28] f880f527 50 push eax f880f528 ff74240c push dword ptr [esp+0xc] f880f52c 05f0010000 add eax,0x1f0 f880f531 50 push eax f880f532 ff15d0f880f8 call dword ptr [Modem!_imp__KeInsertQueueDpc (f880f8d0)] f880f538 b8160000c0 mov eax,0xc0000016 f880f53d c20c00 ret 0xc Which is equivalent to: NTSTATUS UniStopReceiveComplete(<standard args>) { KeInsertQueueDpc(&DeviceObject->DeviceExtension->CompletionDpc, Irp, DeviceObject->DeviceExtension); return STATUS_MORE_PROCESSING_REQUIRED; } For the code to work correctly, modem.sys has to make sure there is always only one IRP with that completion routine active. It means, such IRPs should be serialized before they go to the lower driver. I don't know if modem.sys actually serializes them, or it just (wrongly) assumes there won't be such a case. The device path exerciser may bombard modem.sys with series of similar IRPs (for example those with 2B0018 (?) IOCTL code). If two such IRPs are sent by the exerciser and completed before CompletionDpc has a chance to run, the first IRP is lost, and I believe this is why the IRP gets stuck. It is absolutely bad idea to queue a per-driver DPC with an IRP argument, without making sure those IRPs are serialized. The driver should queue those IRPs in some list instead (using Tail.Overlay.ListEntry), and the DPC should then handle the list.

Hi

I am writting a SD (Security Digital) driver for WinXP/Win2000, after SD driver was installed. I wish that when I format the SD, there are only FAT and FAT32 available for choosing.

How to do that

Is it possible to do that by adding something in driver

By the way, my SD driver was written in SCSI miniport.

Thank you anyone who can give me a help
