    - 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: WaitCommEvent 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: WaitCommEvent Tag: 39547

    - Add new HW Wizard - how to auto install a nonPnp Device Hi all.. I have a Nokia30 GPRS Modem which has no Pnp. So when I plug in the modem, it is not detected by add new hardware wizard. To install the modem I do the following: 1) start HW Wizard 2) select Yes, HW is alreday connected 3) Add a new HW Device 4) install from a list 5) Modems 6) dont detect my modem, I will select it from a list 7) Then I select the modem and define a COM port. now the modem works. But I have the install the modem at 100+PC's, so I want to automate the install process! Is there any way per script or code to do the same as I described automatically?

    - 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? Tag: WaitCommEvent Tag: 39520

    - 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. Adadurov. alexei.adadurov_nspam_@mtu-net.ru Remove _nspam_ when anwering by e-mail. Tag: WaitCommEvent Tag: 39518

    - 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: WaitCommEvent 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: WaitCommEvent 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: WaitCommEvent 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. But if I use "IoBuildSynchronousFsdRequest" to build IRP_MJ_READ or "IoBuildSynchronousFsdRequest" to build IRP_MJ_WRITE. It will let the computer to show a black screen.

    - Wnidows 2000 and PCI-Cardbus bridge resources I have seen some articles here and in alt.periphs.pcmcia about the 2MB limitation of Windows 2000 default resources allocated to devices beyond PCI bridges. I have a similar problem to those people because I am trying to write a device driver for a Cardbus card that needs a memory window of 8MB due to the embedded aplication constraints where the card is also used. I am a device driver newbie and I have been reading a lot lately. The Microsoft paper PCIBridge-CardBus.doc that describes this constrains talks about "Windows 2000 DEFAULT Resources" so I assume that these 'default' resources can be changed to a different setting. Does anybody knows how to change these settings? My knowledge about writing .INF files is still pretty marginal and I do not know if I should use the LogConfigOverride in the .INF file of my device driver or if I should change something in pcmcia.inf or even machine.inf. How would a LogConfigOverride instruction in my .INF file could possibly change the resource allocation of the bridge above my device? Juca Tag: WaitCommEvent Tag: 39421

It appears that Uninstall will be completed anly after I restart the machine (Device Manager says so for my driver) How should I install a kernel driver in a way that will not set such limitation on the uninstall process? (I need to make sure that the scenario Install, Uninstall, Install will work) Thanks, Gana Tag: WaitCommEvent Tag: 39409

    - OpenNdis device not working Hello All, what is the "JUNK" in NDISUIO test program. CHAR * pNdisDeviceName = "JUNK"; I am able to see various adapters in my machine but not able to Open Device. I tried to replace JUNK with the device name (\DEVICE\{......}) i was getting from 'EnumerateDevices()' but it is not working. even replacing 'JUNK' with NDISUIO is not working. Please tell me what device name I am supposed to supply here. Thanks and Regards, Bill Tag: WaitCommEvent Tag: 39391

    - GetTempPath() Is there a kernel-mode equivalent of GetTempPath() on Windows XP? What's the best way to choose a system-wide (not user-specific) temporary file directory? My driver is loaded after file systems drivers, so all hard drives are accessible by the time I need to create a temporary file. Thanks. Tag: WaitCommEvent Tag: 39381

    - Driver Installer Well but then they should show that the driver is not signed as well I just tried installing some of the device drivers(for some usb devices), I saw the new hardware found when I connected the device for the first time(After installation), and then I did next, it installed the driver and then the finish button But no unsigned message as is the case in my driver installer So that means its signed, but still why the New Hardware found screen, does this mean that no matter if the driver is signed or not , the new hardware screen will pop up As I have been given the task o getting rid of this new hardware found wizard after our installer installs the drivr and the software, and if requires getting the driver signed then get it done, but even if signing wont ri the new hardware found wizrad then its of no use for me and my company Also for the only one screen, I was talking about Windows XP Pro.. Again I am using just the setcopyinf, so after the installer when the devie is plugged in the new ard ware found wizard pops up and one of the screens reached during pressing next has also this "Driver not signed Thanks a lot again Paul Tag: WaitCommEvent Tag: 39377

    - afd.sys and win32k.sys Problems I have recently been getting the dreaded BLUE SCREEN in Windows XP with the errors being AFD.SYS, 5 times in 2 days and win32k.sys, 3 times in 2 days. I have looked via the net to see if there are any fixes. Several items are available but I am LITTLE CONFUSED, as some people state that those errors can be caused by overheating of your CPU, ???????. Others state that it is a common problem due to TCP settings. This problem can happen within 10 seconds of connecting or 1 hour, only manifests itself if connected to the net.

    - Multiple keyboards with only one routed to windows... Hello folks, since a few months I am willing to set up a solution where I can control multiple virtual PCs over multiple keyboards and mices. One PC, keyboard, mouse combination is the host system. The other combinations shall be virtual PCs via VMware, romote PCs via VNC and similar things. But Windows does the following: It interprets any keystroke of any keyboard as belonging to itself. I found no way to say: This keyboard is for you - just inform me about keystrokes done on other keyboards and don´t care how I use this information. Multiple keyboards can only be done with USB - is there anyone outside with experience in USB driver writing who can outline a complete track of how to solve this problem? There is a ability to filter keystrokes - but I need a filter that is specific to each device... Is it possible to write a common driver that hooks into each driver stack earlier than the normal filter drivers? Thanks for your help. Every program resulting from your help will be given to public domain - please help. Perhaps it would help yourself in some time. With this concept one can work much more flexible with only one machine. Two users, three users - just as you need it... Volker Jung Tag: WaitCommEvent Tag: 39362

Hi developers

I am writing a serial port device driver, however it doesn't seem to work with WaitCommEven

When WaitCommEvent is called on the port, it doesn't block and returns immediately. Moreover, the returned modem status is always zero even though in the mask I had specified certain bits to wait on

ANy help is appreciated!

Check your IOCTL_SERIAL_WAIT_ON_MASK path.
