    - Where can I find the stardand IDE Contorller spec for Windows XP? Hi. If we want to design a PCI-IDE Card, we shall know the stardand IDE Host adapter spec, in order to support a generic device driver. Where can I find the stardand IDE Contorller spec for Windows XP? Does Microsoft define a rule let hardware vendors following it? -- Sincerely Yours, Tag: User Mode Driver Tag: 105684

    - MiniportHalt() function Hi, What sort of things would cause a miniport's Halt function ( MiniportHalt() ) to NOT get caused? I have a deserialized miniport leveraged from the DDK example netvmini. I have even gutted OUT MPHalt() just to set a breakpoint to verify the function is getting called (along with debug statements), and it is not happening. The uninstall/disable window in the Device Manager (which I am using to issue the MPHalt) hangs indefinitely. I can move the window around, but it stays in a "not responding" state. Any ideas? Should I be looking for a spin lock (doubtful due to responsive behavior of window), or is there an acknowledge which must be passed up first to NDIS, etc? I'm sort of fishing for ideas to look into. Thanks, Jan Tag: User Mode Driver Tag: 105676

    - Where to install device drivers so that USB device finds them when it's first connected I'm creating an installer for an application. This application uses a special type of printer that we'll supply to the client as part of a package with the software. I'd like to install the USB drivers that come with the printer into a location where the printer will find them as soon as it's plugged in - i.e. the client won't have to browse to a directory to select the drivers. Is this possible - and, if so, where should I install the drivers. I guess I'm asking if there's a default USB driver search path that Windows traverses in search of a driver before it gives up and ask the user for help. Does a USB device generally know the *name* of the file it's looking for, if not the location? I'm only interested in XP and Vista. Tag: User Mode Driver Tag: 105665

    - installing DLL file in system32 folder Hi, I am creating setup & deployment project for installing my application & driver for xp-32,64 & vista 32-64. By selecting Target platform as "x86", i am installing the driver for all of the above OS using DPINST DiFX tool based upon the versionNT value. Problem: For 64 bit, i want to add my dll file in system32 folder, i.eSystem(64-bit) Special folder. when i added this folder, i am getting error that above folder is not compatible to 64 bit. Yes, it is true, but any other way to install my dll file in above folder? using inf file, is this can be done? I also understand that, when my msi installer package installed in 64 bit system, it will be copied in programfiles-32 bit folder instead programfiles-64bit folder. 2) I went for above approach is that, a single installer for all OS & all platforms, is there any other way that single installer can install multiple platforms?

    - difference between \\\\.\\%c:" & "\\\\.\\PHYSICALDRIVE%d" In application we call the creafile as follows where pVolumeInfo->Extents[0].DiskNumber is the value obtained from IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS ioctl. swprintf(pathBuff, L"\\\\.\\PHYSICALDRIVE%d", pVolumeInfo->Extents[0].DiskNumber); hDevice = CreateFile( pathBuff, GENERIC_READ|GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL); If we open the device like this the IOCTL doesnt pass thru our filter driver whereas if we open it using "\\\\.\\%c:" in place of "\\\\.\\PHYSICALDRIVE%d"as the input parameter then the IOCTL passes thru our filter driver. If I use "\\\\.\\%c:" the ioctls path is something like below(I havent mentioned all the drivers in the path below) 1.NTFS 2.our filter driver 3.volsnap 4.partmgr But if I use "\\\\.\\PHYSICALDRIVE%d" the ioctl path it shows is 1.\Device\Harddisk2\DR3 I dont see any other driver in the path. can any one explain me the difference between the two calls.I thought that both are opening the same object. I checked the IOCTLs path using IRP Tracker. Thanks in advance Tag: User Mode Driver Tag: 105642

    - =?Utf-8?Q?InstallHinfSection_fails_on_Vist?= Iâ??m using InstallHinfSection to install my filter driver. This works well on XP. On Vista 32 it fails with a â??Copy Errorâ?? when I use an Administrator account. InstallHinfSection obviously requires â??computer administratorâ?? access to copy the driver to the drivers directory. My MSI setup checks for Administrator access and it passes since Iâ??m an administer, however InstallHinfSection eventually fails because it doesnâ??t have the access it requires. How can I get InstallHinfSection to be successful using a standard Administrator account or how can I get the Setup to determine the user has insufficient previledges even when theyâ??re an Administrator? Thanks! Chris Harper Tag: User Mode Driver Tag: 105620

    - Enabling/Disabling NDIS 5.1 Intermediate Miniport ( 1-2 Mux) Hi, I have to to complete the development of a Mux written by a now departed consultant and which is probably 98% right. No experience or training in driver development, so I WILL use the wrong terms in phrasing my questions. This MUX is designed to be bound only to Ethernet NICs. When the NICs are bound to the MUX, all other protocols are unbound from the NICs so that after the user binds whatever protocols he chooses to the MUX, the protocols-originated packets must pass thru the MUX, possibly undergo changes, and then get forwarded to both NICs. When the MUX is Disabled thru the Network Connections, it apparently does enough to convince NDIS that it is disabled and the "Status" field reflects that. When an attempt to "Enable" the MUX, the first thing that happens is that the ProtocolReceive or ProtocolReceivePacket function gets a packet sent up from one of the bound NICs and eventually BSODs in the call to NdisMIndicateReceivePacket. My guess is that the MUX does more than what is required in response to the DISABLE command and frees up too many resources required for the ENABLE command. What does NDIS do or call in the protocol side of the MUX to disable it and what is the minimum required by the MUX to comply? What happens when an IM is Enabled? Since the packet reception is the first and last thing I see with WinDbg, I don't know what ENABLING function, if any, would eventually be called and what it should do. What's the best way to block the receipt of packets until the IM has completed the enable process? THX Wes Tag: User Mode Driver Tag: 105613

    - Problem while performing StretchBlt on HP 1010, HP 1018, HP 1020 and Our application uses Windows GDI library to perform rendering and display of data/output onto the devices such as Screen and Printer. While I am trying to print the data onto a series of printers (HP 1010, HP 1018, HP 1020 and HP 3050) I am facing a typical problem. Explaination ------------------ 1. Appropriate DC for the intended device is created [Printer DC created for a selected printer in this case] 2. The data is displayed onto the identified position onto the DC The details of data (fields) to be displayed and their position onto the DC is calculated before the printing begins. If sufficient space is available for displaying/printing a field (data), then it is displayed directly onto the DC (using TextOut. However at situations, the space available for printing (displaying) a piece of data may not be enough. In such scenario, I display such information onto a temperory (display) DC and then perform StretchBlt(....) onto the printer DC. StretchBlt is capable of performing both Stretch / shrink from source DC to the destination DC. [MSDN: The StretchBlt function copies a bitmap from a source rectangle into a destination rectangle, stretching or compressing the bitmap to fit the dimensions of the destination rectangle, if necessary. The system stretches or compresses (shrinks) the bitmap according to the stretching mode currently set in the destination device context]. In this case: - Data is first displayed / outputted onto tempDC - Then StretchBlt is performed from tempDC to PrinterDC The rectangular area on the destination DC is more than source rectangular area then data is stretched If the rectangular area on the destination DC is less than source rectangular area then data is shrinked StretchBlt(...) allows us to specify the raster operation to use while performing this task as its last parameter. Here I am using SRCAND. When I use SRCAND raster operation the data is displayed in actual font size instead of shrinking. This results on loss of data (as sufficient width/height) is not available to displayed data The same operation works on several other DeskJet/LaserJet (including HP) printers. But it fails on the above mentioned set of printers. If I try to use other raster operation such as SRCCOPY, it is able to shrink the data and display properly. I can't use other operations. I have to use SRCAND (as I would like to retain any data that is already displayed within the rectangular area). I also observed that, if the destination rectangular area is more than source rectangular area: then it is able to stretch and display the data without any loss (even with SRCAND raster operation) Please let me know, if any of you have already encountered such problem and any solution Thanks & Regards, Harish Sohani Tally Solutions Pvt Ltd.

    - USB-HID device driver Hi, I wish to develop a usb-hid device driver. I have the following questions: 1) Should it be developed using WDF or WDM? 2) I am referring to the HID standard class. Is it enough as a document to refer all the APIs that can be used for the above purpose? 3) I've downloaded the latest(as on May 06, 2008) DDK from microsoft. Does it have any example codes that mention about USB-HID device driver? Please note that I am referring the following resources: 1) USB Complete -Jan Axelson 2) Making USB Device Drivers Easier Using the HID Class -Stuart Allman 3) Device Class Def for HIDs.pdf I am particularly looking for the example code to do this.

    - Number of IRPS I am writing a virtual disk driver which uses a file as a virtual disk. The disk file can be mounted with a drive letter and normally used. Internally, ZwReadFile and ZwWriteFile in the dispatch routine for IRP_MJ_READ and IRP_MJ_WRITE do the job to write on and read from "disk". As far, everything works fine. In this ,after mounting in explorer window if i make any file copy operation,IRP_MJ_WRITE was called. Also,IRP_MJ_WRITE was called many times after i copied a single file.So my question is, How many IRPs will be sent for file copy operation.How the IRPs are formed by IO manager. How i can trace start and end of copy operation. since,in IRP_MJ_WRITE ,I am writing into a file.Also this file is shared between two driver instances. Looking forward to get reply. Thanks , ND Tag: User Mode Driver Tag: 105599

    - punting back to gdi with EngTextOut not working I am trying to develope a printer driver. When I cannot handle a function I punt back to gdi. It also punts back when succesful so that the mirrorsurface is updated after each call to the driver. I've got punting working for every function except DrvTextOut. EngTextOut returns true, but nothing gets drawn to the mirror surface. According to MSDN "the driver cannot punt to EngTextOut if it has hooked DrvTextOut for a device managed surface.". I have a device managed surface, but I also have an engine managed surface that is used when calling the Eng functions. I wonder if anyone knows: 1. Can I use EngTextOut if I have a device managed surface, even if I am not calling EngTextOut with it. 2. Is there any way to get GDI to draw the text to my mirror surface. Thanks, hwilcox BOOL success = doTextOut(pstro, pfo, pco, prclExtra, prclOpaque, pboFore, pboOpaque, pptlBrushOrg, mix, substMix); if(settings->usingMirrorSurface) { SURFOBJ* mirrorSurf = EngLockSurface(hmirrorSurf); BOOL engRet = EngTextOut(mirrorSurf, pstro, pfo, pco, prclExtra, prclOpaque, pboFore, pboOpaque, pptlBrushOrg, mix); EngUnlockSurface(mirrorSurf); if(engRet && !success) { success = sendRect(&pstro->rclBkGround, pco); } } return success Tag: User Mode Driver Tag: 105590

    - Sharing COM1 with WinDbg I have an embedded device running XPe with a single serial port (also no 1394). The COM1 port is normally used by applications for other purposes. However, I would really like to be able to use this for kernel debugging as well. I tried using /crashdebug option in boot.ini so that the COM1 port does not disappear. The problem is that this does not let me debug on demand, only when a bug check occurs. Is there a way to enable on demand debugging without reserving the serial port for exclusive use by the debugger? If not, the other option would be to have WinDbg monitor for specific debug messages coming from the other machine. My understanding is that this used to be possible with a .waitforstr command, but that doesn't seem to be implemented any more. Is there a way to monitor messages from within WinDbg? Thanks!

    - IoCallDriver Bugcheck Hi, I observed a strange behavior with Intelx64 PCs with my virtual COM driver. When I pass an irp to lower driver (using IoCallDriver()) i get an Assertion Failure - code c0000420 exception and when i forcefully continue it i get a bugcheck. I get this exception when i pass the IRP with one of the vendor specific commands. Also, this exception is not happening frequently. It happens for every 3 out of 5 times. I have used an application to test the sequence. By the way this failure is not happening in either Intel x86, AMD x64 or AMD x86 bit machines. In all the PCs i have installed Vista 32-bit OS.

    - IRP Tracker I see many entries in Device Selection Menu. In that \Driver\Disk is a entry which gives the entries for all the disk in the system. My doubt is,say for a disk I see entries and I notice that a particular IOCTL IOCTL_DISK_GET_DRIVE_LAYOUT reaches only \Device\Harddisk2\DR3 in my case. what is that DR3 ,what does that mean. what are all the other entries like \Device\Harddisk2\DP(2)0X8004400 - 0XC800000+7 \Device\Harddisk2\DP(1)0X4400 - 0X8000000 + 6 can anybody explain what entry is that. why that particular IOCTL reaches \Device\Harddisk2\DR3 from the application eventhough I have filter drivers between. Thanks in advance. Hope I havent confused Tag: User Mode Driver Tag: 105562

    - IOCTL_DISK_GET_DRIVE_LAYOUT doubt I have a lower filter driver(sits below file system driver) From the application I pass IOCTL_DISK_GET_DRIVE_LAYOUT ioctl. I get error as my partition style is GPT. I am not supporting GPT Partition style for now in my driver.so I wanted to log the error in system logs from the driver if it is GPT. But when I tried to log it I see that the particularIOCTL never reaches my driver. Is it possible that file system driver can return error for this IOCTL. I tried checking with irp tracker .when I select my driver and see for the occurence of the particular IOCTL I am not seeing the IOCTL. when I select the corresponding GPT disk in select disk menu I see the IOCTL that is required. Is it that the IOCTL is returned back with error code by file system driver before even my filter receives it. I also see that the error code is INVALID_DEVICE_REQUEST in IRP Tracker. I believed that disk.sys is responsible for the above IOCTL.so I expected my that IOCTL_DISK_GET_DRIVE_LAYOUT should reach my driver.But I am not sure whether my driver receives the IOCTL. Can anybody help on this. does file system driver have any specific check in it. Tag: User Mode Driver Tag: 105560

    - Collate value in Bitmap virtual Printer Driver I am developing a Bitmap virtual printer driver based on Microsoft Universal Printer Driver(Unidrv) Problem is inside driver i am not getting the value of "dmCollate" member of "DEVMODE" I read in MSDN they specify This member is ignored unless the printer driver indicates support for collation by setting the dmFields member to DM_COLLATE. also try after set dmFields to DM_COLLATE but then also i am not getting the value of dmCollate. I tried using PDEVMODEW pDevMode; pDevMode = (PDEVMODEW)pDevObj->pPublicDM; pDevMode->dmFields = DM_COLLATE; But i am not getting the value of "pDevMode->dmCollate" If any one have idea on this topic then please help me.

    - IoAllocateMdl Failure- returns NULL 30% in Vista64 but not in othe Hi, I observed that IoAllocateMdl is returning NULL around 30% of the times in Vista64 but not that much in other OS. I am allocating the MDL memory for 16MB. System is AMD 64-bit 2GB RAM and for other OS also, i tested in the same PC. Do i have modify any settings in vista64-PC to increase the success rate of IoAllocateMdl? I have read in an article, when system loads heavily & runs lack of system pages, it happens, but i tried with SystemPages 0 to not limit of the pages allocation in regedit, but the response is same.

    - PC Restart required after driver unload and before installing agai Hi, I am working on a WDF PCI device driver, driver supports PNP functionality. Problem: when driver uninstalled, i had to restart the system in xp-32 & xp-64 before driver installing again, where as this is not required in vista-32 bit pc. Driver installation: I am currently using DIFX tools DpInst for installing & uninstalling the driver. I also verified that my driver unmaps the resources before uninstalling the driver using MmUnmapIoSpace to unmap the PCI memory resources. Device doesnt support power managment capability, so driver also not supporting any power managment functionality, instead it just registers the callback & wont do anything inside. Since this problem is existing only in xp, do i have to take any extra care to avoid system restart? and also, after uninstall system doesnt prompt for restart also.

    - IOCTL_VOLUME_ONLINE and IOCTL_VOLUME_OFFLINE Hello: Turning around connect and disconnect disk devices I look at IOCTL_VOLUME_ONLINE and IOCTL_VOLUME_OFFLINE functions. However I donâ??t find any examples jet. I test this (in c#): SafeFileHandle h = CreateFile(â??\\\\.\\Physicaldriver3â??, GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, IntPtr.Zero, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL | FILE_FLAG_WRITE_THROUGH, new SafeFileHandle(IntPtr.Zero, true)); if (!h.IsInvalid) { long bret = 0; bool ret=DeviceIoControl(h, IOCTL_VOLUME_OFFLINE,IntPtr.Zero,0,IntPtr.Zero,0, out bret, IntPtr.Zero); â?¦ Where IOCTL_VOLUME_OFFLINE is 3, meanwhile IOCTL_VOLUME_ONLINE is 2. The GetLastWin32Error returns 50, I thing â??ERROR_NOT_SUPPORTEDâ??. The Physicaldriver3 is an USB Memory stick dervice. I know others ways for disconnect USB, but my target is to reconnect the USB without human intervention.

    - Generating a driver without DDK,... Hi, i have a situation here which is really true. I have a old laptop, running windows 2000 professional and there is no space left for the DDK from Microsoft. I want to write and test some (simple, monolithic) drivers, targeting 2000/XP/Vista which handle a special device over USB. So the situation is that i dont have a lot of space for ddk on my machine and i am looking for a way to write a driver, compile it into a native image and all this WITHOUT the MS DDK. Is there such a way, a minimal package of compilers, headers, not bigger than 200 MB? I already have livekd and WinDbg here, but no compiler so far and no environment. The environment should be as small as possible and the compiler should be capable of inline assembly. Is something like this available somewhere? I am not kidding, i really have no space left here on the machine. This may sound funny but this is really the situation.

    - extra WHQL warnings My app calls UpdateDriverForPlugAndPlayDevices and it works. The driver is installed, the device works, everybody is happy. Except... If more than one instance of the model in question is on the bus (it's a USB device), then I get not just one WHQL warning but at least one more. And the pattern is very weird. Let's say the user plugs in one of my devices, and my app calls UpdateDriverForPlugAndPlayDevices, and the user gets a WHQL warning, and she says continue, and everything works. Peachy, right? Now she plugs in a second device and she gets two warnings. Weird! Let's say she says continue two more times and then plugs in a third device. Now she gets three warnings, but the weirdness is just getting started. She plugs in a fourth instance of the device and she gets one warning (expected) but then she plugs in a fifth instance and gets two warnings. Remember, I get the extra warnings even if all but one instance of the device in question already has the driver. But, just to be paranoid, I made sure I was not calling UpdateDriverForPlugAndPlayDevices again due to re-entrant delivery of messages to my window. Of course, I am looking to inhibit the extra WHQL warnings. Any ideas? Pete Gontier http://www.m-audio.com/ pete (at) m-audio (dot) com Tag: User Mode Driver Tag: 105510

Hi

What is the major difference between user mode driver and application dll , is
that user mode driver call Win32 API about device and hardware ?

Can user mode driver read/write IO and set DMA channel ?

What is the difference between traditional user mode driver and new UMDF ?

Thank for your teaching .

> Can user mode driver read/write IO and set DMA channel ?

No. It can execute USB transactions though.

> What is the difference between traditional user mode driver and new UMDF ?

What is "traditional user mode driver"? I cannot understand this.

UMDF's advantage is that the device is properly integrated to the OS's
framework of supporting this kind of devices (so all apps written to this MS's
framework will be able to use the device). This is how UMDF driver differs from
the user-mode DLL.
