    - IPrintOemUI::DocumentPropertySheets I want to modify the value of DEVMODE during this timing, is it valid? But according to the DDK, in the CPSUICALLBACK-typed callback function, the IPrintOemDriverUI::DrvUpdateUISetting method should be called to inform the driver. However, the DEVMODE value is not currently supported by the UI setting. In IPrintOemUI::CommonUIProp I modified the DEVMODE values and so far its working.

    - help:one question about driver verifier When I test my usb driver by driver verifier, I find the system will crash when I remove device.I trace the driver and find the crash will happen after the irp of removal has been finished. The bugcheckcode of Numega driverworkbench is 0xc4 .It means driver verifier detect violation. I can transfer the data by the driver . Here is the Driver Verifier setting for Windows 2000. 1). Install the driver via INF. 2). Click Run -> type verifier 3). Click on Settings Tab 4). In the Verification Type, check "Special Pool", "Force IRQL checking", Pool Tracking", "I/O Verification" (Level 1) 5). Select the Driver files that belongs to your test device. 6). Click "Verify" button below. 7). Click "Apply" button. 8). Modify the boot.ini and put /debug to enable the debug mode. 9). Reboot the system. Tag: How to make rescan for new hardware Tag: 39585

    - Generating interrupts before my driver is loaded ? Hi All, I have a faulty PCI device which generates faulty interrupts. The device generates interrupts before my driver is loaded. This does not seem to bother WIndows NT 4.0 (probably it does not bother Win2K also). After my driver is loaded and I connect to the interrupt, it emmidiately calls my ISR routine and .... My questions are : *) How come it does not bother windows ? *) What does Windows do, with a PCI device generating an interrupt, before it's driver is loaded ? *) Does Windoes behaviour depend on the PC's HW (PIC/APIC) ? *) Does Windoes behaviour depend on the BUS causing the interrupt ? *) What will happen if the PCI device will cause a faulty interrupt after I Unload/Disable my driver ? *) Does Windoes behaviour depend on the whether or NOT this interrupt is shared ? *) Did Microsoft change it's behaviour between NT 4.0 to Win2k to WinXP ? *) What are the details of what Microsoft does when I connect/disconnect from an interrupt ?

    - Synchronization in filesystem drivers Hi, I am developing a filesystem filter driver, I have it to the point now where I am recording filesystem events by storing them in a queue, which is then processed (and emptied) by a system worker thread. Currently I am recording these events in the dispatch routine, to synchronize with the worker thread I am acquiring a spinlock (which the worker thread also has to acquire). So just a couple of basic questions: The dispatch routine will execute at PASSIVE_LEVEL, right? which means that using spinlocks is perhaps overkill? Can I use some other synchronization object, maybe mutexes, resources or critical sections? This would be better for me because then none of my code executes at DISPATCH_LEVEL whilst the lock is held, and I can work with pagable memory no problems. Assuming mutexes/whatever are OK, do I have any worries using them in a filesystem filter - are there any issues regarding blocking APC delivery - i.e. being alertable/not alertable?? Finally, what would the be the most appropriate sync object? I really can't decide between mutex/event/critical section etc.. Thanks, James Tag: How to make rescan for new hardware Tag: 39548

    - Driver Installer Hi I have used this newsgroup so far and am able to do this I have an inf to write an installer for a usb device, so I have SetupCopyInf to copy and update thed river into Windows Now is there anything else that I can do to improve the user experience when they install our device There are things like vid,pid, class of device that are mentioned in the newsgroup, but since I am new, I am not sur whether I have to use these or not Now the way the installer or the four lines of code that I have written works is 1.You run the installer first, after that when the device is connected, new hardware wizard pops up, you click next there 2.On the next screen you select a driver from the list of drivers presente 3.Then click next and the driver is finally installed(i think ) and the device is ready to b used Now I know since the driver is not signed, since its mentioned on the screen 2, maybe we have ge it signed I have seen that for most installers the screen 1 or for that matter 2 never comes, you run the installer, you see a message that driver is not sined do you still want to install and then click yes there and after installation when device is connected, you dont again have to select the driver that you want to use for your device from a list of drivers available So maybe I have to use some more functions to do that All i need is some pointer / suggestion to which functions I can use and will look them up Thanks a lo Shan Tag: How to make rescan for new hardware Tag: 39547

    - UpdateDriverForPlugAndPlayDevices does not call AddDevice in Windows 2000 Using the UpdateDriverForPlugAndPlayDevices appears to work fine for the installation of an initial multifunction device in Windows 2000. However, when used to install subsequent devices, there is no call made to may AddDevice function. As a result, when my DIF_NEWDEVICEWIZARD_FINISHINSTALL function attempts to pass it's information to my driver, there is not extension into which the driver can store it. This is failure to call my AddDevice function for subsequent devices is true regardless of whether I use the INSTALLFLAG_FORCE or not. Does anyone know why UpdateDriverForPlugAndPlayDevices fails to call my AddDevice function in Windows 2000 but works fine in Windows XP and 2003 Server?

    - USB power management problem? Hello, all! While testing recently developed USB measurement device I found a problem with power management that I still can't resolve. Device is single-interface single BULK endpoint device. Device driver is DDK's BULKUSB sample with a couple of IOCTLs added. When the device is plugged into Vitek 2-port USB hub, Windows 2000 crashes (3 machines) with STOP 0x0000001e - KMODE_EXCEPTION_NOT_HANDLED or reboots unexpectedly (old PIII machine), after installation of device driver. With SoftICE installed, a page fault is reported in the driver, with a very strange stack trace, even before the DriverEntry is called. When the device was plugged in the Windows 98 system (by accident), a dialog appeared, saying that USB cannot provide enough power to power the device. Our device reports a maximum consumption of 180 mA, in it's configuration descriptor. Then we've changed this report to 100 mA and the all began to work. Can this be a feature of Windows 2000 power management in that BULKUSB sample does not process gracefully? Thanks in advance, Alexei N.

    - USB device driver installation problem Hello all! I'm expierencing the following device/driver installation problem. We developed a specialized measurement USB device and a BULKUSB-based driver for it. With the most of our test systems installation of device and its driver is not a problem. But with one machine running Windows 2000 Professional + SP4 it turned to hell. When I plug in the device it is detected ('BioSensor USB device', as it's USB string descriptor for device says). Then Device Manager asks for the INF file and I point to the file. And after a second it says that this file contains no information on compatible devices. Setup log (setupapi.log) in the highes verbose level showed nothing useful. The log goes like: .... file bm_usb22.inf opened... .... searching for compatible device ID: usb\vid_71E4&pid_0005&rev_0001, usb\vid_71E4&pid_0005 .... no compatible device ID found (error 0xE0000228) I used NTDDK's usbview to find out if PID, VID and RID were read OK, and it seems they were. (I could also see it from setupapi.log.) Using the REGEDIT I found that device manager creates a node in the registry under HKLM\SYSTEM\CurrentControlSet\ENUM\USB\ with correct VID and PID. This happens on a machine running Microsoft Windows 2000 with Service Pack 4. Problem could not be reproduced on another machine with the same software configuration (i.e. Windows 2000 with Service Pack 4). FYI: KB822831 did not help. Your suggestions? Reinstallation of Windows 2000? Other? Thanks in advance, Alexei N. Adadurov. Tag: How to make rescan for new hardware Tag: 39515

I went through debuging a call to malloc() to try to find out where the link between virtual memory and physical memory is stored, but ended up with calls to HeapAlloc() that are stepped over by the debugger.

    - USB devices need drivers (again) when you change port?!? If I connect an USB device to an USB port the "Found new hardware wizard" pops up. Installation works and all is fine. However, if I disconnect the device and reconnect to ANOTHER port on the PC the wizard pops up again! The drivers are already there so why the ---- does it need to install the drivers again? After some fiddling in the registry (HKLM) it seems that the driver database is implemented in such a way that each peripheral is identified by its connected port... duh! Does anyone know of a work around? I would really like to install the drivers ONCE and dont care much about which USB port the user chooses to plug into.

How I need to define CmdSendBlockData (and other parameters), when the following data structure exists for the printer (Bit Image): The CmdSendBlockData is "<ESC><2A><m><n1><n2><d>" m = Print mode 24-dot double density n1, n2 = defines the width in dots d = databytes, bit image data The data need to have the following format (Height: 24 dots = 3 bytes): d1 d4 d7 d2 d5 d8 d3 d6 d9 These are 9 data bytes, which defines a 24x24 dot image. My problem is, that the driver outputs the raster with the correct format Thanks for helping Eric Tag: How to make rescan for new hardware Tag: 39506

    - IoAllocateErrorLogEntry fails. Dear All, I am using IoAllocateErrorLogEntry and IoWriteErrorLogEntry to log the events. Does the system free the memory allocated for ErrorLogEntry structure using above function on its own? Or is there any explicit way of freeing this memory once IoWriteErrorLogEntry is done. Is there any restriction on the number of events that can be logged for each driver? In my driver I realize that after logging say N errors successfully, IoAllocateErrorLogEntry always returns NULL to me. Can anyone help me in figuring out why this is happening? Thanks in Advance.

    - usb2.0 suspend/resume issues I am working with a usb2.0 composite device under winxp which has three interfaces printer,scanner and mass storage device. I have my own host2.0 stack and my composite driver takes care of the device. micrososft client drivers are loaded for the different functions(usbstor.sys,usbprint.sys and usbscan.sys). I have two problems during suspend/resume. 1. before initiating suspend, i access the mass storage device and leave the explorer associated with it open. after wake up i am able to still access the mass storage device, but i am not not able to access my printer. pls note that this problem does not happen when i close all the documents or the explorer from the mass storage device. 2. when i try to disconnect the device, my parent composite driver deletes all pdo and gets unloaded, when i connect the composite device again, windows says that " the previous instance of the mass storage driver is still in memory and so culdnt load the mass storage driver", in this case mass storage driver is never loaded unless i reboot the system. i strongly feel that the leaving the handles open from the mass stroage device has got some impact, becos i never encounter such problems when all the handles associated with the mass storage device is closed. any suggestion is appreciated, thanks Tag: How to make rescan for new hardware Tag: 39477

    - Help! Why I create IRP_MJ_READ/IRP_MJ_WRITE always cause computer down. Hi, all I am a person who is a greenhand to develop drivers for windows. I develop a driver that in which I use "IoRegisterPlugPlayNotification" to listen to another device's arrive/remove. And in the callback function, I use "IoGetDeviceObjectPointer" to get the DeviceObject of that device. And then, I can use "IoCallDriver" to send IRP to it. But I face a problem. If I use "IoBuildSynchronousFsdRequest" to build IRP_MJ_PNP and send to that device, it works well.

    - Odd problem with mirror driver changing display I have implemented a mirror driver based on the DDK sample, and it works except that when it is enabled rubberbanding shows differently on the real display on XP, e.g. if I click and drag in an empty area in Windows Explorer, with the driver disabled, I get a black outline filled with a transparent blue gray shade, but with the driver enabled, I get a dotted black outline with no shading. Does anyone have any ideas about what is causing this and how I can fix it ? tia J. Wesley Cleveland Tag: How to make rescan for new hardware Tag: 39467

    - Win DDK 3790 cannot compile with VS 6.0, but linking error with VS. Hi, I had a simple driver compiled and working under Visual Studio 6.0 and Windows 2000 DDK on a Win@K system. I wanted to try to get it compile on my WinXP professional system. I got Windows Server 2003 DDK installed, from the documentation, it seems to suppose to work with WinXP and 2000. When I tried to compile the project, I got the following error: G:\WINDDK\3790\INC\DDK\WNET\NTDDK.h(23) : fatal error C1189: #error : Compiler version not supported by Windows DDK It failed on this statement. #if _MSC_VER < 1300 From Walter Oney's book, I was suppose to use Win.NET DDK and VS 6.0. I only saw this server DDK, WinXP, Win2000 DDK. Which DDK was I suppose to use? Does this version of DDK not suppose work with VS 6.0? I tried to compile the same project under VS.NET 2003, it did not give a compiler version problem but I got a linker error: something.obj : error LNK2019: unresolved external symbol ___CxxFrameHandler referenced in function __ehhandler$?somefunc@@YGHPAUSomestuct@@@Z Release\somedriver.SYS : fatal error LNK1120: 1 unresolved externals I am not sure what caused this linker error. I am fairly new in this driver development, any pointer would be greatly appreciated. Thanks in advance! Linda Yang Tag: How to make rescan for new hardware Tag: 39464

Hi

I'm writting an installator for usb modem (W2k, C++). I can install it and
uninstall.
For installing i'm using UpdateDriverForPlugAndPlayDevices. But after
uninstall i can't install drivers again until i do hardware rescan or plug
out and plug in device. So my question is: how to make rescan for new
hardware programatically with API functions?

thanks in advance
P

Use CM_Reenumerate_DevNode(devInst, 0) to Enumerate sub-device tree from of
which "DevInst" is parent. if you use

To locate the root devnode, you can use CM_Locate_DevNode with Null as 2nd
parameter.
