    - Driver Chain Manager Hi, all! Did anybody write driver, compatible with DCM? Task is to write magnifier. I think, this will require tapping video driver. DCM establishes a set of rules, governing display driver interception. First of all, I should estimate complexity and volume of work. Now, I am trying to write test chain driver, intercepting DDI calls. Questions: 1) I can't compile driver, using WinDDK. Linker can't resolve DCM calls. I have dcmkrnl.dll, dcmuser.dll installed. I do not have any .lib files.(Do I need them or I can manege with .dll files?) What should me adjust? 2) Documention, that I have found, is insufficient. I don't have samples, that I can modify. Does anybody have samples or detailed documentation? 3) DCM is a relatively new component. Is it reliable enough? Yuri Tag: Unidrv - Printable Area Tag: 46051

    - Thread in driver ?? Hi All ! Anyone has worked with Numega Studio to write a Driver ? I must write a Driver filter for Com Port and synchronize system time between 2 computer via Com port ( call them Server and Client ). In the server side , there is one User application to active the driver and User can click on a Button in application to tell the Driver to implement synchronization time with the Client . In the Client side , There is no application , only Install Driver . And the Driver in the client side must use a Thread to detect when the Signal from server has come . SO, My task now is that I must create a Thread in Driver in order to detect when the signal has come to the Port . Pls explain , how can i do this work? I have create a Thread and put it in the DispatchCreate ( I use Numega to write driver ) . So now , How can I detect the Signal came to the Port by this Thread? Pls explain the Mechanism ! Thanks in advance ! Tag: Unidrv - Printable Area Tag: 46043

    - Generic Device Identifier I am attempting to create a program that will inspect our companies machines and determine any drivers needed for devices based on the hardwareID, DeviceID, etc. One problem that I have encountered is a case where the mouse hardware ID is a generic ID. For example, the hardware ID on a Dell laptop is listed with the generic identifier of: ACPI\PNP0F13,*PNP0F13 This could match any number of mouse drivers, i.e. Alps touchpad driver or Synaptic, etc. The correct driver, or at least the driver shipped with the unit is an Alps touchpad driver. Do cases where a generic hardware ID is listed (and I'm sure there must be others --USB drivers come to mind) mean that any driver/INF matching that ID --whether it is Alps or Synaptic-- will work properly? Secondly, is there a way to determine which is the proper manufacturer/driver to install? Many thanks! JW Tag: Unidrv - Printable Area Tag: 46030

    - Strange Shutdown Problem I'm writing a driver for a PCI-Express device, although the "-Express" part should be irrelevant for this discussion. I started the driver from Walter Oney's driver wizard, and the power management code is essentially unchanged from the wizard code. Windows XP SP1a Checked. (I haven't tried Free; I suppose I should...) I can load, unload, and restart the driver to my heart's content. On a system restart, power state goes to D3, driver unloads, everything is happy. But when I try to do a system shutdown, most of the time it gets everything shut down, my power state goes to D3, my driver (apparently) unloads, the kernel debugger disconnects and waits for a reconnect, the screen goes to blue, and that's it. The power doesn't go off. SOMETIMES a shutdown works fine, but most of the time, I get this hang. If our device is not plugged in, it shuts down OK. Anybody have any wild ideas for me to try? I don't THINK it is a driver issue; I don't think the debugger would disconnect if my driver were still running. Any "I saw this once and here's what I did" stories welcome. -- - Tim Roberts, timr@probo.com Providenza & Boekelheide, Inc Tag: Unidrv - Printable Area Tag: 46028

    - Wheel tab on mouse control panel Does anyone know how the mouse control panel decides whether to show the "Wheel" tab? Our experiments seem to be indicating that, rather than using some kind of IOCTL_MOUSE_QUERY_ATTRIBUTES call, it may be looking at the PNP ID of the currently installed mouse (at least for PS/2). The symptom is that if we install our driver using a compatible ID (PNP0F13) the tab shows up, but if we install the exact same driver on a device/platform specific PNP (e.g. SYN0010) the tab goes away, with no other changes. If this guess is correct, is there some kind of registry key or something that would cause the Wheel tab to come back? Some of our customers are complaining about it going away. -- ../ray\..

    - Loading two IM driver on PPC2003 Hi, I am trying to load two IM derivers on my PPC2003 (i-mate). Currently I am working with sample 'passthru' code given. I made a two copies of passthru one named as IMDRIVER it's miniport section named as IMDRV1 and second one is PASSTHRU and it's miniport section is PASS1. Now, I load IMDRIVER first and have seen that it works fine. than i load PASSTHRU , I found that in the protocolBindAdapter function of the PASSTHRU ,the miniport secion of IMDRIVER (i.e.IMDRV1) is not comming and therefore PASSTHRU does'nt load successfully over IMDRIVER. Can any body shade light on it ?? Any suggesstion will be a great help for me. Thanks Niraj Tag: Unidrv - Printable Area Tag: 45967

    - 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.

    - 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: Unidrv - Printable Area Tag: 45920

    - 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)? Best regards, Tobias Tag: Unidrv - Printable Area Tag: 45905

    - 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. Tag: Unidrv - Printable Area Tag: 45887

    - Does bulkusb.sys support overlapped I/O? Hi all, I'm currently adapting the bulkusb.sys driver from the latest DDK (Win2K3 DDK). Does anyone know for sure whether it supports overlapped I/O or not? All they seem to say is that it's multi-threaded safe. Thanks. Tag: Unidrv - Printable Area Tag: 45850

    - 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: Unidrv - Printable Area Tag: 45844

    - video mirror driver Hi, I need to modify the mirror driver to get a simple information: whatever is the application that modify the desktop i need to know what is the region that Windows draw and/or update (RECT). I'm sure that this information is in the struct SURFOBJ of DrvBitBlt and DrvCopyBits so hooking this call I can grab such information. The question is: how can I send this information to UserMode Application? Can I use a IOCTL or a ReadFile ? Thanks, Pierluigi M. Tag: Unidrv - Printable Area Tag: 45838

    - sources/Build.exe alternate source file location question Is it possible to specify a source file that is in a different folder than the current one or the parent folder? It seems that when I specifiy "SOURCES=foo.c", Build.exe looks in the directory above and then the current directory. I would like to be able to specify "SOURCES=..\AltDirectory\foo.c" , but Build.exe whines and complains when I do. Any ideas? Thanks, John Tag: Unidrv - Printable Area Tag: 45806

Hi All

I've tried crazy values for the *CursorOrigin attribute in the GPD, but can't find any difference in the command stream that is generated.
Does the *CursorOrigin attribute make sense only for the application or Unidrv adds commands in the stream for this attribute

Regards
Naresh
