    - WDF Class Filter Driver Installation Hi, I was wondering if anyone had experience installing a CLASS filter driver on an already existing setup class. I have found limited resources on the subject (at least for a class filter driver), and I haven't found anything on msdn on how to install a class filter driver with WDF. Their link points to here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/devinst_d/hh/DevInst_d/specinst_708d78ad-ba66-40a0-946a-a0bb261e8a8a.xml.asp which directs you to use an app to do the following: 1. Call SetupInstallFilesFromInfSection for the [upperfilter_inst] section. 2. Call SetupInstallServicesFromInfSection for the [upperfilter_inst.Services] section. 3. Call SetupInstallFromInfSection for the [upperfilter_inst] section, once for each class key it wants to register the upperfilt service for. However, I think WDF is a different beast as it requires the wdfcoinstaller to install the runtime. So I am not sure if this method is what I should do (and besides it didn't work). So, I found from osronline that with wdf we are supposed to use WdfPreDeviceInstall and WdfPostDeviceInstall. How do these fit in with a class filter driver? >From what I understand, I can use those functions along with CreateService to install my filter driver's service, but what about registration? As far as I know step 3 in the older documentation says to use SetupInstallFromInfSection to register the class filter driver. Does that only add the "UpperFilters" value to the class key in the registry? Does it do anything else? When I tried to use it I didn't see any entry appear Any help on how to install a class filter driver using the WDF/KMDF would be much appreciated. Thanks! Tag: DDKVersion.xml ? Tag: 86737

    - PoStartNextPowerIrp special case I'm curious about something in "Calling PoStartNextPowerIrp" in the DDK docs. In most cases PoStartNextPowerIrp is supposed to be called just before the power IRP is passed back up or completed, except in the case of filter drivers for system power IRPs where PoStartNextPowerIrp is apparently supposed to be called before passing the power IRP down. What makes that case different? (from filters and device power IRPs or non-filters and either type of power IRP) Tag: DDKVersion.xml ? Tag: 86712

    - KMDF Class Filter Drive INITSTARTFAILED Hi, I'm working on a class filter driver but to start I have installed the filter as a device upper filter on a device of the class that I am to filter on (both have services installed at boot time). It works fine as a device upper filter with the exception that in the registry key I have noticed that it sets INITSTARTFAILED to 1 for the enum key of the service (i.e. .../System/CurrentControlSet/Service/myService/Enum). However the count is 1 as is the nextInstance. I thought that if the service truly did fail that the count would be zero? The filter driver installed correctly as it does what it is supposed to do. Furthermore, setting a breakpoint on my driver entry results in the behavior expected (registers my device add and everything). It works as far as I can tell except for the INITSTARTFAILED that is set. I have deleted the key and the next time I boot it is back again. I think this may be a problem because when I try and have the filter be a class filter driver, I get an INACCESSIBLE_BOOT_DEVICE (7b) I just want to make sure this INITSTARTFAILED doesnt' have anything to do with this... In order to make the filter a class filter I have added to the key corresponding to the class guid in currentcontrolset/control/classs with UpperFilters myFilt. I have also tried putting in a CoInstallers32 wdfcoinstaller01005.dll,WdfCoInstaller since when I installed the filter as a device filter it put those values in the device instance key (am I missing something else?) So I guess I really have two questions 1. Anyone know why INITSTARTFAILED would be set to 1, but yet load the service and it function properly? 2. Anyone know if for a CLASS filter driver if there are any other values I have to set besides the UpperFilters in the registry key for the class? Thanks in advance! Tag: DDKVersion.xml ? Tag: 86711

    - USB to Ethernet miniport Adapter: SetPower Request handling. Hi, I am writing a USB to ethernet miniport driver. My question is about SetPower Request handling when device is unplugged during Standby. The Device is connected and PC is put to Standby, When the PC is in Standby mode the Device is unplugged. Now the PC is made to come out of Standby. As soon as the PC comes out of Standby we get SET_POWER Request. Since the Device is no longer connected I am returning STATUS_ADAPTER_REMOVED from the SET_POWER request. It seems to work fine in most of PC's but in a few of PC's the MiniportHaltHandler is not getting called. I tried NDIS checked build and we get a message "Assertion failed NDIS_STATUS_SUCCESS == ndisstatus" The other messages that I get are as follows "**** source file: d:\xpsprtm\net\ndis\sys\ndispwr.c, Line 1164 NdisDevicePowerOn: Miniport 82EB9AC8, PowerOn Failed by device driver for the miniport, error C0010018! NdisDevicePowerOn: Miniport 82EB9AC8, PowerOn Failed by bus or device driver for the miniport, with error C0000001!" We get the same status in the PC where MiniportHaltHandler is getting called. According to the DDK documents we should always return STATUS_SUCCESS. But since the Device is no longer connected to the PC, returing STATUS SUCCESS seems to be illogical. If we have to return STATUS_SUCCESS from the SET_POWER request all the time. Is there a specific place (function call) from where we should return STATUS_ADAPTER_REMOVED. I would be very grateful if somebody can throw some light on this. Regards, Anuj Tag: DDKVersion.xml ? Tag: 86700

    - Help needed on writing a pseudo audio driver Hi, I have done lots of ground work, but could not find any satisfactory explanation on this. My requirement is like that - i will have an pseudo audio driver registered. For one of my application (voice chat application), I will select this driver for audio i/p and o/p. Application will deliver any incoming voice to the pseudo driver for audio o/p (in normal case, it would have been given to the sound card driver in the system). The pseudo audio driver will forward this voice to somewhere else(lets say X). The pseudo audio driver will get user voice i/p from X and forward it to the voice chat application (in that case X is acting as a microphone source). Initially I was thinking it won't be possible in windows. Then I came across MSVDM where they have written a driver for storing voice to a file instead of o/p it to sound card. I was thinking to tweak this for my purpose, but, as I am new to windows driver I could not understand few things. How about writing a audio filter driver? Please guide me as to what will best suit my requirement. I must admit windows is a very difficult bitch to grab. It is taking hell lot of time. the more I read more I get confused. An early reply will be very much appreciated. Any pointers or help in this regard will be highly appreciated. -paul Tag: DDKVersion.xml ? Tag: 86684

    - cursor background drawn with wrong bitmap. Hi, I want to achieve screen rotation with increment steps of 90 degrees. To start with I am targetting only 180 degree rotation.I have developed display driver for this. This is just a punting driver. When I get a drawing call, I am rotating the source, repositioning bounding RECT and punting it using Engxxx calls. I am facing problem with cursor back ground. When I move cursor, bounding rect of cursor is drawn with wrong image. For example when I move cursor on the desktop, cursor bounding rect of old location will be redrawn with the image which will be there if I dont rotate the screen in my driver. To achive perfect screen rotation do I need to develop any more supporting drivers like miniport filter driver etc? if yes, what should be function of that? Regards, Sunil Tag: DDKVersion.xml ?

    - ScsiDebugPrint Okay, I'm pulling my hair out over an issue that does not deserve near the amount of time I've devoted to it. I'm trying to get ScsiDebugPrint to work in a ScsiPort miniport driver. Here's what I've got: - A test "driver" with only DriverEntry. It #includes miniport.h and scsi.h. I have 4 calls to ScsiDebugPrint() in DriverEntry, with 0-3 values for first the DebugPrintLevelArg. - I link against scsiport.lib. I'm using the latest WDK. - I've tried running with a checked build of scsiport.sys that I rammed into the sys drivers dir of my target box (having turned off file protection in the registry [SFCDisable]). - I run with a debug serial hook-up to my target PC. - I've got Debug Print Filter registry entries: DEFAULT, DPFLTR, IHVBUS, IHVDRIVER, IHVNETWORK all set to dword 0xf. - If I change the driver to instead include wdm.h, link against wdm.lib, and use DbgPrint(), this works. But of course I can't use DbgPrint() w/ a ScsiPort miniport driver. Help, anyone? Thanks. -mat loik@<company>.com Synopsys Hillsboro, OR Tag: DDKVersion.xml ? Tag: 86647

    - Device removal and "create requests" When the DDK says to fail "create requests" after succeeding an IRP_MN_QUERY_REMOVE_DEVICE, is it talking about IRP_MJ_CREATE? I'd previously thought most drivers don't do anything for IRP_MJ_CREATE. Is this a typo, since it also says that protection against new open handles should already be taken care of by the OS except in broken old Windows 98/Me (and open handles is what IRP_MJ_CREATE implies, isn't it)?

    - A sort of "query remove lock"? The documentation for IRP_MN_QUERY_REMOVE_DEVICE in the DDK mentions that if a driver has an outstanding reference against itself from IRP_MN_QUERY_INTERFACE that it should fail the query remove IRP. That makes sense. So, some query interface reference count needs to be checked before succeeding a query remove (except there's no need to wait for it to drop to 0 like with a remove lock because it can't be predicted how far into the future the interface reference would finally be released). Also, some mechanism needs to make query interface IRPs begin failing after a query remove IRP handler has begun. Otherwise letting out an interface reference would race with the query remove, an interface reference could be let out afterwards, and then the device couldn't later be removed as should be expected when a query remove succeeds. The "toaster" sample does the first part but not the second. That's a mistake, isn't it? (also, this made me think what other sorts of operations should be waited for in IRP_MN_REMOVE_DEVICE vs. IRP_MN_QUERY_REMOVE_DEVICE. Is it that IRP_MN_REMOVE_DEVICE can wait for operations that take a short period of time to finish and clean up while IRP_MN_QUERY_REMOVE_DEVICE is for ones that would take so long that removal should simply be canceled?)

    - PCI Express Standby issue Hi Folks, We are trying to develop a nic driver and are noticing that after standby the system crashes: more specifically, the first interrupt after standby causes a crash. More background: Since the standby removes the power to the card, we save the pci config space before the standby operation. After the system comes out of standby, we reset the chip (to clear any stale state), which in turn resets the express link. The driver then waits for a while (for the link to establish back) and restores the pci config space. After that we able access the chip internal registers however, when we enable the interrupts, the first interrupt immedaitely cause a crash. Has anyone seen this behavior. The driver is being tested on a windows 2003 server x64 platform. -thanks Tag: DDKVersion.xml ? Tag: 86594

    - IRP_MN_STOP_DEVICE on Windows 98 I'm not sure if Windows 98/Me still matters, but I hit a section that mentions it in the middle of the 2003 DDK PnP area. I know that the old Windows are a little different from the newer Windows, but I'm wondering if this is a case of different or just plain broken. What I'm wondering is if a device receives IRP_MN_STOP_DEVICE is it supposed to queue incoming IRPs or fail them? For resource re-balancing queueing sounds right, but for disabling a device from Device Manager failing them does (or they'd be queued for a very long time until the device was re-enabled or the requester finally gave up and canceled them). The problem is doesn't Windows 98/Me send IRP_MN_STOP_DEVICE for both of these. Is there any way to distinguish the two situations on that old platform? Tag: DDKVersion.xml ? Tag: 86592

Please tell me ways to implement, if I have a second HID USB keyboard with multiple Top Level Collections, (in this case a Microsoft remote,) so that the inputs from this device will not mingle with those from the primary keyboard, and be available to programs as, say, WinProc messages? I don't want to touch the system supplied class and miniport drivers. Thanks in advance. Tag: DDKVersion.xml ? Tag: 86584

    - Creating a virtual Port Hi Everyone, I Made a Driver using WINDDK samples. And i was able to add the printer using it. It prints the file fine on the Physical printers ports. Now i want to create a virtual port so that files get printed ( On Disk) So please help me with the following two options 1) i wont to avoid (Print to file port option) .because it pops up the dialog while printing the file and asks for the file name. I want to hide this dialog and it should take the default name send by the driver. OR 2) So can anyone please let me know how do i add virtual printer port. This looks a better solutio to me. Thanks to all Vik Tag: DDKVersion.xml ? Tag: 86576

    - Is hidclass.sys appropriate for my device? Hi, I am currently involved in a project that involves the design of a proprietary USB device. This device is under design and its purpose is to get configuration information from a PC via USB and transfer that information to an Infrared device. We would also like to be able to read the configuration information that is stored in the device. I had hoped to use the hidclass.sys driver and thus avoid the task of writing a device driver. I am finding out as I go along that the report may be limited to 4 bytes of data, our configuration information is 32 bytes. Would you recommend continuing along this path and writing multiple reports to get the full configuration to/from the PC or could you recommend another driver or maybe a Minidriver ??

    - Help With NDIS WHQL/Logo Process I have a NDIS driver that works great. I'm just want to install it without getting the prompts about Windows Logo Testing. I have been attempting to read through the documents from Microsoft on logo testing and WHQL but am getting lost in the multiple hundred page documents they provide. What I am looking for is an ordered list that I can follow that will explain what I need to do to get it completed. I found a page from Microsoft that has something like this but that is where it tells to download document after document...and that it is before I even have to buy a certificate. I also don't want to purchase a certificate and then find out that I can't do it with my product or I have to implement a bunch of features that I don't need just to conform to Microsoft's specification. If anyone can provide some guidance or has experience doing this with an NDIS driver that would be great. We may even be willing to pay for some consulting services that can perform this task for us.

    - KMDF and Smart card reader driver Hello, I want to develop a specific smart card reader driver. I would like to know if I can use KMDF? I have doubt specially with the function SmartcardDeviceControl which completes IRP. Once SmartcardDeviceControl is called, is there a way to the framework KMDF to know if the request is still available and a way to destroy this request on framework point of view. Thanks for your answers Tag: DDKVersion.xml ? Tag: 86557
