    - Device not recognized after wake up - Power management Hi, I am working on a usb2.0 device and developing a host driver as modelled as MS driver stack. After wake up from S1/S4 mode, the device gets removed , but not loaded again though physically attached to the system. All the FDO and PDO are getting deleted and the function driver for the device is unloaded during process of waking up. I expect the usbd driver to load it again, but it doesnt happen. What may be the reason? I appreciate your help on this. Tag: Is it possible to support DMTT_BITMAP Tag: 38566

    - Driver verifier issue in XP Hi, I am having an issue with my driver when driver verifier is enabled in Win XP SP1. The problem is that I always get BugCheck DRIVER_IRQL_NOT_LESS_OR_EQUAL(D1) exactly when i try to acquire a spinlock. I am sure that the spinlock is allocated in non-paged pool and has been initialized. Bugcheck code is as follows: BugCheck D1, {eff0b4ff, 2, 0, eff0b4ff} Arguments: Arg1: eff0b4ff, memory referenced Arg2: 00000002, IRQL Arg3: 00000000, value 0 = read operation, 1 = write operation Arg4: eff0b4ff, address which referenced memory Arg1 and Arg2 are same, isnt this odd? Can somebody explain this. From the dump I get BUCKET_ID: 0xD1_CODE_AV_BAD_IP_SupaCemul!OpenComPort+a7 This is the place where spinlock is acquired. What does CODE_AV_BAD_IP mean? Why doesnt verifier in Win 2k complain. Code works in XP without verifier enabled. Is this an issue in verifier of Win XP?? Find below the dump snip if it could help.

    - IRP_MN_FILTER_RESOURCE_REQUIREMENTS Hi, I've been developing a driver, but I have some problems, in the debugging I see that when I'm installing my device after receiving IRP_MN_FILTER_RESOURCE_REQUIREMENTS (which I pass down the stack) the stop device routine is called followed by the cancel stop routine and so the installation ends and my device is never functional. Do you have any ideas why is this happening? Should I handle IRP_MN_FILTER_RESOURCE_REQUIREMENTS? -- How? Thanks a Lot Rodrigo Tag: Is it possible to support DMTT_BITMAP Tag: 38557

    - 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: Is it possible to support DMTT_BITMAP 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.

    - 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: Is it possible to support DMTT_BITMAP 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: Is it possible to support DMTT_BITMAP 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: Is it possible to support DMTT_BITMAP Tag: 38525

    - 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: Is it possible to support DMTT_BITMAP 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?

    - usb with ohci?..any simple tutorials?..code? 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: Is it possible to support DMTT_BITMAP 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.

    - 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: Is it possible to support DMTT_BITMAP 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: Is it possible to support DMTT_BITMAP Tag: 38437
