Bug Check in Filter Driver

Hello All, For my disk upper filter I turned on the driver verifier. While changing the power states (standby,hibernate or reboot) I get DRIVER_VERIFIER_IOMANAGER_VIOLATION bug check. The I/O error code is 0x21A (The previously-set IRP_MJ_POWER status has been converted to STATUS_NOT_SUPPORTED). In my filter driver I do not handle any power IRPs. Do I need to handle any power IRPs in filter driver. Here is the bug check analysis for your information. This happens only in Win7. Thank you. Regards, Sushma *******************************************************************

Filter driver on boot device

I am writing a KMDF filter driver attached to the boot drive, so it loads with start_type = 0. I only want one read/write request in flight at a time. When I set the following in addDevice, I get a crash with "Inaccessible Boot Device:" WDF_IO_QUEUE_CONFIG_INIT_DEFAULT_QUEUE (&ioQueueConfig,WdfIoQueueDispatchSequential); ioQueueConfig.EvtIoRead = FilterEvtIoReadWrite; ioQueueConfig.EvtIoWrite = FilterEvtIoReadWrite; ioQueueConfig.EvtIoDeviceControl = FilterEvtIoDeviceControl; status = WdfIoQueueCreate(device, &ioQueueConfig, WDF_NO_OBJECT_ATTRIBUTES, WDF_NO_HANDLE

DevCon to remove ghost devices "remove failed"

Hello, I just pulled a Virtual Tape Library out of my backup environment and am now having some stability issues with the remaining devices. In working with the vendor, they suggested I check for ghost tape drives that could cause issues. Sure enough they are there. When using devcon, I run: devcon findall =tapedrive And a ton of devices like this show up: SCSI\SEQUENTIAL&VEN_IBM&PROD_ULTRIUM-TD3&REV_8711\5&AF4D2D0&0&00050E: IBM ULTRIU M-TD3 SCSI Sequential Device I then try to run a remove and get: D:\temp>devcon remove "@SCSI\SEQUENTIAL&VEN_IBM&PROD_ULTRIUM- TD3&REV_8

Windows7 send wrong USB data payload after wake from sleep mode.

Hello, could someone give me a hint? A little introducion: We have machine (I C2Q, 2GB RAM with Windows7). There could be connected up to 8 identical HiSpeed USB devices. USB driver is based on WDM (3790.1830) bulk USB sample. Now, when computer enter sleep mode, then wake from sleep, communication with devices crash because wrong data are send to device. This occur regardless our devices are connected or not (driver loaded or not during sleep time). I have USB tracker, and recorded USB communication show, that second and third DWORD of some packet are bad. For example: expect

Hi, I am using 7600.16385.0 WDK build environment for building the driver, used the xp build env for 32 bit OS(xp, vista, win7) and server 2003 for 64 bit OS. DPINST tool is used for installing the driver. Problem: ---------- Driver is installing fine in win-7 32 & 64 bit OS with above build environments But it is failing in xp & vista OS. Earlier, I have used WDK-6000 build enviroment, worked fine.

Service installation section in this INF is invalid

Hi, I am new to Device Driver Development. I'm learning the basics to understand. I need to develop a USB driver for our company device which has to perform bulk transfer. I tried the usb, umdf samples present in the WDK. I modified the files under step 4 and tried installing in win XP. I used free build. I'm getting the following error Add Service: Binary "C:\WINDOWS\system32\DRIVERS\WUDFRd.sys" for service "WUDFRd" is not present. #E032 Error 0xe0000217: A service installation section in this INF is invalid.

"Print to File" option with Unidrv

Hello, I have a printer driver that I wrote which is based on the oemui sample in the DDK. I noticed recently that if the user clicks the "Print to file" checkbox on the print dialog, the filename dialog will open as normal and the postscript file will be created but it will be empty (0 bytes). Also, my driver will continue to function as it normally would had the "Print to file" checkbox not been checked. I'm a little confused. Since my driver is derived from the IPrintOemUni2 class and the "Print to file" option is for producing a postscript file, shouldn't a postscript drive

How to use WdfDeviceIndicateWakeStatus?

Dear all, I'm developing a set of WDF-based drivers for a specific bus like USB. This bus has several levels. Each level node works as "hub", except the terminal leaf device. In order to save power, all devices, hubs and terminal leaf devices, can enter D2 while system is still S0. Only the terminal leaf device has remote wakeup capability. When a terminal leaf device sends remote wakeup signal to root, we need to wake up all hubs between root and the terminal leaf device? From WDK document, we learned WdfDeviceIndicateWakeStatus is useful. My question is: If we call this fu

MmAllocateContiguousMemory and non-paged pool size

The documentation on MmAllocateContiguousMemory says that it attempts to allocate memory from the non-paged pool, and if this fails then "it attempts to perform the allocation from available unused pages". Firstly, what on earth does that mean? Secondly, will the memory "from available unused pages" still be non-paged? I will be accessing it at DISPATCH_LEVEL so I need to be certain. My guess is that the memory available in "unused pages" is somehow mapped into the non-paged pool ... thus increasing the size of the pool. My next question is about the size of the non-page

IoSetDeviceInterfaceState problem when used with multiple instance

Hi - I am using an interface to signal an application from a kernel driver. The driver call IoSetDeviceInterface state to change the status which is monitored by the application via WM_DEVICECHANGE messages. With a single instance of the interface everything works fine. However, with multiple instances of the interface, sometimes the application does not see all the notifications. This behavior occurs ONLY in Vista & Windows 7; XP works fine. The instances of the driver interface are created by specifying the ReferenceString parameter to IoRegisterDeviceInterface(). Are

One driver for multiple OS

Is it possible to use one build environment to create one bulk USB driver binary to run on WinXP, Vista and Windows 7 using WDK 7600.16385.0? Or do I need 3 driver binaries per platform (eg x86, amd64)? -- Thanks, Eric

GDI hook driver

Hello everyone, I've been looking around for some printer/display driver which can hook a GDI function. I would like to understand how you can 'catch' a function like 'CDC.LineTo(...)' in an application and do something else like saving these instructions to perhaps a textfile. In the DDK I've found some samples like MSPlot (Printer), Mirror (Video). But they're so different from eachother, except from their initialization proces. Now I've read about the Source file, Makefile and the operation when createDC(...) is called. So the basic idea: In the application some

How to add another target to VidPN in WDDM driver?

Thanks all for the replies before and I'd like to ask few more questions related to VidPN management of WDDM driver. When WDDM miniport driver enumeratse child devices and connected external monitors, it first detects its all child devices in DxgkDdiQueryChildRelations, and next check each child actually has connected output in DxgkDdiQueryChildStatus. So, to implement adding another(virtual) monitor I faked one of given PDXGK_CHILD_STATUS parameter(HotPlug.Connected) to have true. And I filled up followed EDID query requests as well. Then I could see another monitor attached on d

Our disk's driver run properly compiled for 32bit and not for 64bi

Description of driver: Our software encrypts our virtual discs and hard disk partitions too. Both run over our driver - which is something like filter driver, because it uses ntfs and fat drivers to makes real operations on this discs. In this driver we take a block from the disk (ask to ntfs/fat driver), decrypt, make changes etc... And of course attach and detach disk to system (find letter etc...). Creating of virtual discs (real file in filesystem) is made by our client application - not by the driver. The driver must be sign to run on 64bit OS, we sign it by older certificat

Number of DPC-Objects allowed in wait queue ?

I started device driver development with help of (maybe) outdated book of art baker (et.al.) "Windows 2000 Device Driver Development" (2001). I think the basics remain still valid for WDM. But I wonder if the following is still true for newer Windows versions (WinXP, Vista, Win7): "[...] there is only a single instance of a DPC-object allowed in the wait queue that refers to the same function.

What MRAM Products are there for Windows?

I'm seeking info from any gurus out there about MRAM. I know that some manufacturers are now supplying 4MGB chips (26 bucks a piece) to hardware vendors. My questions are: 1) Are there any commerical products that allow a Windows box to use MRAM? 2) Is it possible to add some kind of MRAM card? 3) Are there any software products that allow easy-use of MRAM? 4) Are there any hard disk drives that an MRAM cache? I am aware that MRAM is costly, so I'm wondering if it is possible to add a card or something (say with 8 chips = 64 MB est cost = 180 bucks for the chips). Also,

Camera Driver

I work for a hardware manufacturer and we're including a still camera in our PC. We need to provide an interface for applications to access and control this camera and don't know how best to do this. My reading so far suggests there are 3 options: A DirectX filter, a WIA driver or a WPD driver. Most documentation seems to suggest that we should use WPD, but as an application developer, I would expect to be provided with a DirectX filter, and as far as I can see WPD does not provide this. Given that we need to support windows XP onwards, which route should we take? All advice

Kmdf USB driver install on XP stops WDM driver install of other de

WinDDK 7600.16385.0 was used to compile the WDM driver source for Dataq DI720 A/D converter, which was derived from the BULKUSB WDM sample. To obtain a starting .INF file, the latest BULKUSB sample was modified to just change the device and GUID. With a little editing to the .INF file to set appropriate default parameters, to everyone's amazement the amd64 driver worked on Windows 7 Ultimate, and the i386 driver worked on Windows XP Professional. However, in Device Manager on both systems, the device was listed in its own class instead of under "Universal Serial Bus controllers".

memory mapping and WRITE_REGISTER_UCHAR

Thanks to help that I got from a previous post, I was able to get my driver rebuilt and going again. I am very much appreciative. Here is a tricky question that I may not fully grasp yet: My driver is for a PCI card. Hence the address space is 32 bits. The memory on my card is 16 bits. So there is some mapping that occurs. Now, I did a little calculation already that tells me that byte 4 in PCI space is byte 2 in my card's memory, byte 6 is byte 3, etc. That works fine enough so that when my Windows application writes to byte x, the write goes to byte x/2. No problem t
