    - Check Irp->PendingReturned in IoComplete routine In IoComplete routine, sometimes it check Irp->PendingReturned and call IoMarkIrpPending if the flag is set. Is there any rule for this? According to DDK document, it says.... ================================================================= Any driver that sets an IoCompletion routine in an IRP and then passes the IRP down to a lower driver should check the IRP->PendingReturned flag in the IoCompletion routine. If the flag is set, the IoCompletion routine must call IoMarkIrpPending with the IRP. Note, however, that a driver that passes down the IRP and then waits on an event should not mark the IRP pending. ================================================================= However, bulk usb sample code in DDK. In IoComplete routine of set device power up, FinishDevPoUpIrp, it checks Irp->PendingReturned and call IoMarkIrpPending if flag is set. In IoComplete routine of set device power down, FinishDevPoDnIrp, it doesn't check this flag. Why??? Does it have something to do with IoCompete's return value?

    - FakeModem sample Hello, Does anyone have any experience with the FakeModem sample? I wanted to start experimenting with a modem driver and I thought I would try compiling and playing with the FakeModem example found in C:\WINDDK\2600.1106\src\network\modem\fakemodem. I made no changes to the code, just compiled and installed. I then fired up HyperTerminal--and nothing. Not a thing. Are there any other modem samples somewhere that I could look at?

    - Firmware files location My driver need to write the hardware firmware files every time it starts. The files are a bit big ~100K uncompressed and ~60K compressed. Where should my INF file store these files? We prefer not to couple the firmware files with the driver since the driver might manage different versions of the firmware. Yariv.

    - GDI_DRIVER Driver compilation with VS7.1 IDE Hi, Introduction: ********** I am writing a display mirror driver, I am trying to use the VS7.1 (.NET) IDE to compile the driver, conversion to an .vsproj solution is done by the 'Source to DSP converter' app provided with 'SoftIce driver suit'. The Problem: ********** The mirror is build of to files: the miniport driver and the display driver, no problems has occurred converting compiling and using the miniport driver, in contrast, conversion of the display driver failed: the 'Source to DSP converter' doesn't support GDI_DRIVER conversions, SO..., I tried to do some tricks: I have changed the TARGETTYPE of the GDI_DRIVER to DRIVER and then used the 'Source to DSP converter' with the new source file, the result was a new .vsproj compiling a .sys driver I have changed the name of the driver to be .dll and removed the 'DriverEntry' DLL entry point from the project configuration, still, using the new driver causes an 'Unhandled kernel mode exception', using the display driver compiled by the 'source' makefile works fine and doesn't reproduce this problem, what may cause the problem? what went wrong during the 'Source to DSP converter' conversion? what special configurations are required for a GDI driver? Should there be any specific entry point to a GDI_DRIVER? Thanks in advance, Nadav, Tag: How to expose new device nodes Tag: 38463

    - PNP Manager I have developed a failover driver for a fibre channel medium changer device on Windows 2000 that is tightly dependent on the PNP Manager. When I pull the cable out of my hardware, one of my Win/2K systems immediately rescans the bus without any intervention on my part, notifies Device Manager of a hardware change, and sends IRP_MN_SURPISE_REMOVAL to my driver. I have another Windows system on which the rescan does not automatically take place. On that system I have to use device manager to manually "Scan for hardware changes" before the surprise removal notification will happen. In order for this driver to work, the scan needs to happen automatically. How do I get this to happen? Does it depend on Windows or on the fibre channel adapter card and its driver?

    - HCT 11.2 - TestImports Problem Can someone help me understand what this error means: ERROR: 71: Public Imports Test failed to run, TestImports function call failed. This is from a run of HCT with an NDIS IM driver. What's odd is the NDISTEST 1c_KernelCalls passes (I assume that TestImports checks for invalid kernel calls from an NDIS driver). Also, the driver is not binary compatible (it's only used for XP). Would that cause this problem. Tag: How to expose new device nodes Tag: 38439

    - Service Name Issues With CheckInf I get the following error with checkinf from Windows 2003 DDK: Line 77: ERROR: (E22.1.1014) Service Net6IM already using binary $WinDir$\system32\drivers\net6im50.sys. This is odd since I am using the same service for both W2K and XP installations. However, I've added a target OS version in the Manufacturer section and am using separate NDI's for the OSs that the inf is used on. Is this a WHQL requirement that different services must be used on different OSs or is this a problem with the chkinf tool? Tag: How to expose new device nodes Tag: 38437

    - Audio synchronization I need to synchronize audio with another output device. Can I do this with an interrupt driven heartbeat generated by the output device. The synchronization only needs to be visually accurate, in other words I'm not concerned about microseconds, but I would like to be accurate to 100 milliseconds. My initial thought is to have my interrupt routine begin a 100ms segment of audio. The next interrupt would stop the previous segment (if the audio is behind) and then play the next segment. My "interrupt routine" would probably be a thread at the application level waiting for my device to interrupt. I don't think I would need to place this in my device's DPC. I've been reading up on the Wavform Audio Interface, is this the correct area? There must be some support for this built into the interface to facilitate the usage of a scroll bar to scan through an audio file. My questions are, am I looking in the right place and a corrollary, how flexible is the interface? I don't want to waste research time going down a false path.

    - I refuse to believe this.... When installing a printer driver, Add-Printer etc etc, it prompts me for a printer name just before finishing the installation. I have two printer models, but would like to use the same printer name.. without having to manually enter it. Is there really no way that I in my INF file can provide a default printer name ?

    - Device Object NULL in completion routine Hi, In my FSD filter, I am building up my own IRP to send to the lower driver so that I can get some info (QueryDirectory) about a directory. The problem is that when my completion routine is called, it contains proper data, but the device object I get is NULL (is this normal?). Also my stack location seems to be wrong since it no longer contains the parameters (minor/major functions say), that I setup. Any clues?

    - Maximum StrMini Driver Size?? I am developing a stream class mini driver based on usbcamd. Today I ran into an extremely odd BSOD that I initially thought was related to some memory management code that I had added. It turns out that the problem is that I added code. I have reached the state where the following will take the driver from functional to non-functional. int i for(i=0;i<1;++i){} I can add this, or equally useless code in a variety of different functions (none of which are called) and cause this error. The BSOD message is about a page fault in the non-paged area caused by ks.sys. It occurs when I attempt to render the capture pin on the filter. The driver can be loaded and unloaded as many times as one likes without error. I am wondering if this can be related to SRB_PAGING_OUT_DRIVER? I noticed that the INF file (intelcam) I copied does set PageOutWhenUnopened registry setting. Is it possible that enabling this can cause this error or is there some other possibility? This is running on XP Pro SP1. Regards, Tom Udale Tag: How to expose new device nodes Tag: 38374

    - Sound Capture Hi, I have a problem.... actually it is a thing to do on my list, and I wondering if anyone can give me a hint or two on where to look for tackling it. Well, all I need to do is to intercept and capture sound (wav or raw doesn't matter) that only a certain application generates opposed to whole system (all apps.). The app. uses none of the fancy directx stuff, just plain win32 APIs (MCI I think) Any thought on how should I begin looking for this solution?

    - Device Extension for NDIS miniport driver I am writing a NDIS miniport driver. From DDK documentation, I was told to use NdisRegisterDevice instead of IoCreateDevice to create a device object. However, the same documentation also says that the device extension for an object created with NdisMRegisterDevice is reserved for use by NDIS and cannot be used by the driver. I want to modify the device extension to store any state status and information. How can I do that? Thanks, Billy. Tag: How to expose new device nodes Tag: 38370

    - SetupCopyOEMInf - avoiding prompts during install I have a new driver install and an old driver install that use different source media locations. I have been using SPOST_PATH for the OEMSourceMediaType when I call SetupCopyOEMInf. This is leading to setup problems because the old INF is selected by SetupAPI during install. This INF points to an installation directory that does not exist and the user is prompted for the correct location of required files. I think the root of this problem is that the PNF has to old source media information. Should I call SetupCopyOEMInf with SP_COPY_REPLACEONLY copy style to update the old PNF if it exists and then call it again with the SP_COPY_NOOVERWRITE copy style to copy it sure the PNF has the current source path info (if needed)?

    - Hardware ID in win 2000 and UpdateDriverForPNP My .inf has an entry for that says _01 %xyz.DeviceDesc%=xyz.Device,USB\VID_xxx&PID_yyy I am trying to install the driver for the device for the case where the device is plugged in but the Add New hardware wizard was cancelled by the user. Now, if I pass the HWID "USB\\VID_xxx&PID_yyy", updateDriverfor.. fails with 20B (no_such_device) I think. Then if I change it to "USB\\VID_xxx&PID_yyy&Rev_0001" (which I know from the registry whenever I install this successfully in the nice ol' plug device after software installation way) AND also change it in .INF, my updatedriver.. succeeds and device is shown working properly with the correct name in device manager. So my question is, what is that Rev.. thing? is it like a hardware revision? if so, I would not know every possible revision number in advance and would like to keep it generic for the device? How do I achieve that? What is the correct entry in .INF and correct HardwareID to be passed to the function updatedriver.. Thanks for your time. Tag: How to expose new device nodes Tag: 38363

    - What's the rule to call IoCompleteRequest for power Irp? I understand when should call IoCompleteRequest for PnP Irp. For Power Irp, it seems have different rule. I am confused, I don't know when I should call IoCompleteRequest for power Irp, when should not. For example, bulk usb sample code of XP DDK. In set device power state process, IoComplete routine of power Irp calls IoCompleteRequest to complete Irp when power up. However, IoComplete routine doesn't call IoCompleteRequest when power down. Why it needn't call IoCompleteRequest? What's the rule to call IoCompleteRequest for power Irp? Can anyone tell me? Best Regards Jackal Huang Tag: How to expose new device nodes Tag: 38354

Hi All
I have to write a usbccgp.sys like driver ie which
exposes new device nodes for a composite usb device ie we
have to assign a separate PDO to each function of a
composite device.
How do I proceed ?
Thanks in advance

Why can't you use usbccgp.sys? To learn about exposing new devices, go
through the src\general\toaster\bus sample in the DDK.
