    - QUERY_REMOVE_DEVICE notification I get query_remove_device notification in my 1394 device driver. But I am not getting it in my application. I get DEVICE_REMOVE_COMPLETE and add_device, both to my driver and application. This is how I registered for 1394 device change notifications in Application code. devBroadcastInterface.dbcc_size = sizeof(DEV_BROADCAST_DEVICEINTERFACE); devBroadcastInterface.dbcc_devicetype = DBT_DEVTYP_DEVICEINTERFACE; devBroadcastInterface.dbcc_name[0] = 0; devBroadcastInterface.dbcc_classguid = t1394DiagGUID; hNotify = RegisterDeviceNotification( SharedData->g_hWnd, &devBroadcastInterface, DEVICE_NOTIFY_WINDOW_HANDLE ); In my driver, I am simply passing the Irp down the stack for Query with success in status. Should I do something here. 1. I want to receive notification of 1394 devices to all devices in the 1394 network. 2. How can I get a notification in App *before* driver receives QUERY/IRP_MN_REMOVE_DEVICE. 3. I also want to know if how I can get DBT_DEVICEREMOVEPENDING in application so that application do some clearing before device is removed, if possible. Will this notification come even for surprise_remove. Thanks. Tag: Beginers question Tag: 38540

    - why IoCompleteRequest DDK explaining IoMarkIrpPending explains: " Unless an IRP's dispatch routine completes the IRP (by calling IoCompleteRequest) or passes the IRP on to lower drivers, it must call IoMarkIrpPending with the IRP. Otherwise, the I/O Manager attempts to complete the IRP as soon as the dispatch routine returns control. " I understand when to call IoMarkIrpPending. What I didnot understand is why to call Irp pending. I also *understand* IoCompleteRequest is something like saying to IoManager " Thanks, I am done. Now I return back Irp to you". (Consider a simple case where application sends Irp to top most driver and top most driver has to handle it and no other lower driver bothers to know this Irp.) 1. I think IoManager should not touch our Irp (once passed to us) unless we pass it to next layer in IoCallDriver or unless we complete Irp. I am curious to know why this is not the case. Why IoManager bothers to monitor Irp(even if I didnot say 'I am done' with Irp) after returning from dispatch routine. I agree that it makes sense for IoManager to look into Irp if I said 'I am done, go ahead'. 2. I know (1) is wrong assumption, then I think we dont have to call IoCompleteRequest in dispatch routine because if I handle/process the Irp and return from dispatch routine(without passing down and without calling IoCompleteRequest), *anyway* IoManager will complete because I didnot call IoMarkIrpPending. Thanks for comments. Tag: Beginers question Tag: 38538

    - Installation of non-PNP legacy serial devices? Some time ago, I wrote a filter driver for a legacy game device, the Spacetec SpaceOrb 360. It relied on the serial PNP system and installed itself based on the detected device (similar to, I think, the mouser example). Unfortunately, after release I discovered that many older models of this device are NOT detected by XP on initial boot. The initial driver worked OK, it just couldn't be installed because XP never asked for the driver. My first attempts at fixing this got out of hand quickly (I installed an enumeration driver that latched into the port enumeration system, grabbed new ports, queried them for the device, and released them if it didn't exist). It worked well but was way too complicated and also had the minor problem of totally locking up the system when the device was unplugged. I want this to be as simple as possible. Are there examples out there of how to force installation of a legacy device onto an existing serial port? I want the user to be able to say "I have this device on COM1:" and install it there without relying on PNP to find the settings (it should still work the PNP way, though...). -->VPutz Tag: Beginers question Tag: 38536

    - Output Binary... Hi , I wanted to know what is the binary for Monitor Driver.. When I installed Monitor driver for my Samsung SyncMaster 753s all I could notice was .pnf .inf and .icm file.. Does Monitor Driver do not mean a .sys or .dll file ? Can you tell me ? Actually I wanted to write functional driver for my monitor.. I understand that writing funtional driver for monitor is in other words writing a monitor driver.. So is it that monitor driver is just an .icm file ? If it is so then if I want to write lower level class driver for monitor class how do I do it ? My options are to write either functional driver for monitor or lower level filter driver for monitor.. Any help will be appreciated... Thanks in advance... Neel Tag: Beginers question Tag: 38528

    - passing miniport driver adapter context pointer to IRP I am writing a NDIS miniport driver, and starts from the DDK sample, Netvmini. I want to use the miniport driver adapter context to store the state information and incoming/outgoing packets. However, I do not know how IRP (DeviceIoControl routines) can acess the adapter context. I heard that I should store the adapter context pointer under IRP->FileObject->FsContext when IRP_Create is run. How can I do that? Should I store the context pointer under the device extension of the device object created by NdisMRegisterDevice? Thanks, Billy Ng. Tag: Beginers question Tag: 38525

    - Port Monitor disappears on reboot Hello, We are working on a custom port monitor (I've posted about it here before). It works mostly fine, except that on certain machines the port monitor will disappear completely after a reboot. The DLL is still in c:\windows\system32 and all the registry keys still exist. This only seems to occur on systems with a certain motherboard, the Asus A7V8X-X. Tag: Beginers question Tag: 38521

    - Certification of Network devices. Do the Network device tests (for a Wireless LAN NIC) need to be run on a multiprocessor PC ? The 11.2 HCT seems to be testing for this (we get an error from one of the tests that says that a multiprocessor PC has to be used). I recall discussions that the multiprocessor requirement was eliminated and that nework devices (NICs in particular) could be certified on single processor PCs.

    - Resources Conflict Hi, Currently I'm trying to develop a driver for a bridge chip (PCI-VME bus) on a SBC. So first I installed W2k, and of course the system asks for a driver for this non-common hardware (which is Pnp compatible). The problem is that it has some resources conflict with another chip, so when I install my basic driver I can not get to the point where I start the device. Is this a problem of hardware?? or can this problem be solved by software?? and how?? Thanks in Advance!! Tag: Beginers question Tag: 38509

Does that support multiple devices Question2. I plug in a bulk transfer device. The device is detected by windows. When I plug out the device, the plug and play manager pops up notifying of the unsafe removal. In another case I plug in two or more of such devices. And when I plug out or try to do a safe removal from the plug and play manager, windows crashes.. or I'm shown a blue screen. Is there any fix for the driver. Or Is there any modification that needs to be done in the driver sample. pls help. Tag: Beginers question Tag: 38504

    - 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?

    - 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: Beginers question 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?

Howdy all, well I was wondering if anyone had come across some really simple...but good tutorials on the ohci specification with code...and how to use it with a usb device...very low level stuff...for example mapping to the registers in memory ...testing for bits...and with simple code examples that would explain why......not working through the os though...a kernel driver possible...like that is done in linux :) Thanx for any help :) Ben Tag: Beginers question Tag: 38453

    - CMOS sensor - USB Trust 120 Spacec@m Webcam Hello. Can someone tell me the name/model of the CMOS sensor in the above webcam? Or an hint on how to retrieve it? I don't have datasheets. Trust and Google don't help. The name is not written on the hardware. I analyzed the drivers for windows (40 MB of zipped shit for just a driver..hu..): nothing The only information is the it has 28 pins: **nothing** more. Any idea would be much appreciated. Thanks in advance. Tag: Beginers question Tag: 38441

    - 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: Beginers question 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: Beginers question 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. Brian Tag: Beginers question Tag: 38421

    - Picture transfer protocol Folks, I would like to acquire images and change camera settings under program control, using a Nikon Coolpix camera connected via USB, and the Nikon SDK (which I have). I gather this requires PTP and WIA, but am so far entirely ignorant of these technologies. I'd really appreciate it if someone would give me a pointer to documentation that could get me started. (The information I've obtained by searching msdn seems pretty disorganized so far.) Thanks much, Matthew Fleming mgf@mcw.edu Tag: Beginers question Tag: 38415

    - Error USBD_STATUS_ISO_NOT_ACCESSED_BY_HW Hello: What is the meaning and cause of usb packet error USBD_STATUS_ISO_NOT_ACCESSED_BY_HW (code 0xC0020000) returned by urb->UrbIsochronousTransfer.IsoPacket [PacketNumber].Status? I am getting this error occasionally (a few percent of all packets) when streaming bidirectional (1 stream out, 1 stream in, simultaneously using 2 alternating urbs for outgoing and 2 for incoming) high speed usb 2.0 isochronous data to a custom hardware device. I am using 16 microframe urbs and the error always occurs on microframes 1, 2, and sometimes 3 of the 16 that are being transferred. All microframes before and after this complete normally. It affects both read and write urbs. OS is WinXp SP1 with USB patch. Usb.h states that "for some reason the controller did not access the TD asocated with this packet" as explanation for this error.

Hi,

I am interested in books concerning Driver development
the following areas:
1. App -> Kernel interactions ( Soft links, IPC, ... )
should be covered.
2. Display driver model, miniport driver.

Any Recommendations will be appriciated.

John.

Well the problem is that your items ( Soft links, IPC, ... ) aren't used in
app / driver comunications. Actually, this is one of the simpler areas,
since most books cover how to handle system I/O calls such as (Open, Close,
Read, Write and DeviceIoControl). There is some sample code around that
shows other methods.

> 2. Display driver model, miniport driver.

I know of no book that covers display drivers. For regular drivers, the
recommended book is "Programming the Windows Driver Model" by Walter Oney.
