    - Disk Class Upper Filter - FILE_REMOVABLE_MEDIA Using the DDK samples (toaster, diskperf), I've been able to write a basic disk class upper filter. I would like to correctly determine if the device is removable media (i.e. usb thumb drive, iPod, etc). If my filter driver is added before PartMgr in the UpperFilter reg value, the below code works correctly. If it's listed after PartMgr, FILE_REMOVABLE_MEDIA is never set in my filter device's characteristics. Is this expected? Can I get this info elsewhere, or do I need to control the order of the UpperFilters? From the toaster filter example (IRP_MJ_PNP -> IRP_MN_START_DEVICE): // On the way up inherit FILE_REMOVABLE_MEDIA during Start. // This characteristic is available only after the driver stack is started!. if(deviceExtension->NextLowerDriver->Characteristics & FILE_REMOVABLE_MEDIA) { DeviceObject->Characteristics |= FILE_REMOVABLE_MEDIA; } **** Any info or pointers would be greatly appreciated.

    - MouseFilter Hi I need to get a filter running where i can add my own mousepackets to the mouse from a usermode program. One of the things i want with the driver is to start and stop it runtime. So first i wanted to get the moufiltr example from DDK running as an upperfilter with the help of an inf file but somehow i cannot get it to work. I tryed to register it as an Class driver for all mouse and i made a service. Only when i start the service from my application with startservice it gives me an error code and the service doesn't run. With the help of some lecture i went to see at the device manager at the mouses but when i look at the option "class upper filters" it doesn't give me any info on if moufiltr is hooked on the mouse. I do see mouclass hooked on it at the upper class filter. My question is , can i run the filter this way or do i need to do it in a different way?

    - USB and IOCTL_PAR_QUERY_DEVICE_ID in language monitor gets errors Trying to use a USB to parallel adpater to communicate with a printer. Ocassionally get an error in the language monitor on a call to pIniPort->fn.pfnGetPrinterDataFromPort for IOCTL_PAR_QUERY_DEVICE_ID. GetLastError: [23]-Data error (cyclic redundancy check). Once this error occurs, the printer does not respond and all subsequent language monitor calls get the error. The error does not clear until the USB cable is disconnected and reconnected, where the printer then responds. What is causing this error and is there a way to clear this error from a language monitor in order to continue operations? The MSDN documentation indicates that the query for IOCTL_PAR_QUERY_DEVICE_ID is supported by USBPrint.sys and that a PJL language monitor that supports this query is compatible with USBPrint. I also tested IOCTL_USBPRINT_GET_1284_ID and got the same results. Any advice on this is greatly appreciated.

    - IoGetDiskDeviceObject Dear all, In my FsRegistrationNotification callback I call IoEnumerateDeviceObjects for each file system and use IoGetDiskDevice to identify mounted volumes in the device object list. Is it safe to assume that if IoGetDiskDeviceObject succeeds that the device object is a volume that I can filter? I ask this only because in the sfilter example they do it a slightly different way, I just wondered if my method is a safe shortcut. My target OS is XP onwards, I know that this wont work on W2K, but that is fine. Thanks in advance, Carly Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting? Tag: 75327

    - win2k audio class driver issue Hi We have a composite usb 2.0 device ( having video & audio functions). The device works absoultely fine on Windows XP with SP2 with standard class drivers. But when the device is connected to a win2k system with SP4, the video function works fine but the audio function doesn't. When the device is connected to system with just usb 1.1 support (windows 2K without SP4), the audio works fine.(uses the standard audio class driver, but 1.1) Is there a known problem with the audio class driver of windows 2k SP4? Do we need to develop a properitary driver for 2.0 audio device? Thanks in advance. ~suu. Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting? Tag: 75320

    - Cleaning up registry after IM driver crash Hi, I have following problem with IM driver development: When driver crashes before it can be normaly uninstalled, I boot another system on the same machine and delete system32\driver\mydriver.sys . Because it is not correct way for uninstalling in registry stays some data and on every system start "New Hardware" dialog appears. When I see into Device Manager, all installed and crashed drivers I see in NIC section like:"DriverName Miniport #number" with yellow exclamation. When I try to uninstall it from device manager, it says: "Failed to uninstall device. This device may be required to boot up the computer." So after some time number of these not functional devices is high. Before some time I had tried to solve it and clean all registry keys with information about this not functional device, but it's not simple, probably I forgot something or I deleted something good and must reinstall all machine... Does exist way to set somewhere startup type for these not functional devices and then to uninstall them by correct way ? Or some other trick how to remove these devices ?

    - accesing drivers on different IRQ levels Hey team.) There's a perticular problem with the driver I am developping. My main driver runs at passive and the other one at higher - looks like apc or even device. I can only access a function that doesn't give me IRP but has the important data that the main driver should receive. How do I transfer that the fastest way. I created a thread in main drv. that waits for events but that goes very slow and async occurs. When I use KeWaitXXX in higher level drv - machine most likely restarts. The best way would be to disable the other interrupt, handle sync/transfer and enable it again. But I don't know how. What would you suggest. Big thanks for answers.

    - DDKBUILD version 3.13 released. The latest released version is 3.13. This version adds quiet mode - the script attempts to reduce all output to stdout to the minimum, simplifying the use of ddkbuild in automated build procedures. Credit goes to Beverly Brown at Mercury Computer for the quiet mode implementation. The Vista DDK (build 5270) is supported. WDF (KMDF1.0) is released and 3.13 supports that as well. DDK's going back to the Windows 2000 DDK continue to be supported. Visual Studio 2005 is supported. In addition a lot of bugs have been fixed. Bug fixes were suggested by Daniel Germann, Thomas Schimming, David Craig, Norman Diamond and probably other people I forgot about. http://www.hollistech.com/Resources/ddkbuild/ddkbuild3_13.zip Using ddkbuild with Visual Studio .NET: http://www.hollistech.com/Resources/ddkbuild/ddkbuild.htm ===================== Mark Roddy DDK MVP Windows Vista/2003/XP/2000 Consulting Device and Filesystem Drivers Hollis Technology Solutions 603-321-1032 www.hollistech.com Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting?

    - Who is the parent? (IRP_MJ_INTERNAL_DEVICE_CONTROL) Hi All, I am using USBBuildVendorRequest to format an URB and then send the URB to the bus driver. In case of XP this will be generic parent driver, for Win2K this is usbhub.sys. I am sending these urbs successfuly if I am inside a function driver. The parent driver for a function drivers is the generic parent/bus driver. It happens that I cannot modify officially the function driver code and I have to use the driver as it is. I am implementing an upper function filer driver. Using the same mechanism for sending urbs my code into the filter's custom IOCTL handler looks like this: // Create the URB urb = (PURB)ExAllocatePool(NonPagedPool, sizeof(struct _URB_CONTROL_VENDOR_OR_CLASS_REQUEST)); UsbBuildVendorRequest( urb, URB_FUNCTION_VENDOR_DEVICE, sizeof(struct _URB_CONTROL_VENDOR_OR_CLASS_REQUEST), 0, 0, 0, 0, 0, IoBuffer, NULL, InputBufferLength, NULL); // use the original irp as an internal device control irp nextStack = IoGetNextIrpStackLocation(Irp); nextStack->MajorFunction = IRP_MJ_INTERNAL_DEVICE_CONTROL; nextStack->Parameters.Others.Argument1 = (PVOID) urb; nextStack->Parameters.DeviceIoControl.IoControlCode = IOCTL_INTERNAL_USB_SUBMIT_URB; ... ntStatus=IoCallDriver(deviceExtension->TopOfStackDeviceObject, Irp); My question is if this internal IOCTL will ever reach the generic parent/bus driver? Is this a general mechanism to talk to the generic parent/bus driver from any place in the device stack above these driver - say upper function filter, function, lower function filter drivers? What if I place my driver as a lower function filter driver - in this case it will be nearer to the generic parent/bus driver? Thanks in advance!

    - Keyboard filter driver for the multimedia and power keys on a usb keyboard.

I used the kbfiltr sample from the DDK and got it working for a PS/2 keyboard, but it doesn't work for a USB keyboard. I've read some other posts and it looks like the multimedia and the power keys are separate HID collections. If this is true do I need to write a HID filter driver for these collections? If this isn't true then what is the best approach to take? Any help would be greatly appreciated. Thanks. Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting? Tag: 75241

    - Page Orientation capability in Unidrv? Reverse Print direction? Looking for a way to reverse the print direction on a thermal printer driver. The Unidrv GPD file has the 'Orientation' feature with the capability for PORTRAIT, LANDSCAPE_CC90, LANDSCAPE_CC270, which work well, but I am looking for a way to reverse the print 180 degrees. Because the Unidrv does not support it directly I think I will need to perform this in a printer graphics dll (renderring dll). I am new to this area of development. After reading and searching for info in MSDN and the newgroups, I found the Watermarkuni sample in the Windows Server 2003 DDK and have reviewed and tested it, but did not get a watermark as with the watermark PCL sample. Should the output be similar? What would be the best way of accomplishing a reverse page print? Can the page image be inverted before it is sent to the printer in a routine such as OEMSendPage() in ddihook.cpp of the watermarkuni WMARKUNI.dll sample? Or is there a better way to do this? Any advice greatly appreciated. Thankyou DaveK Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting? Tag: 75230

    - Sending URBs from an upper function filter Hi Folks, I have a bunch of function drivers for my composite device. The device itself has 4 configurations and I would like to be able to switch between these configurations. As I know the mechanizm to do that is to send an IOCTL via the control pipe to the device's enpoint 0. I chosed USBBuildSelectConfigurationRequest. I am going to catch the IOCTL for configuration change in my filter and inside the filter's IOCTL handler I am going to call USBBuildSelectConfigurationRequest. This function is supposed to talk to the bus driver by sending an internal URB to switch coonfigurations. In USB turms it will send SET_CONFIGURATION (control write setup packet). . My concern is can I send URBs from a filter that is placed on top of my function drivers? Function drivers are already in the system, I cannot control them (different vendor) and still I have to be able to switch between the device configurations. Will my URB send from the filter reach the bus-driver? Is this a correct approach? Best Regards! Dim Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting? Tag: 75227

    - Common Buffer DMA We are developing a bus mastering PCI Nic card. We have decided to use common buffer dma model, where dma could be triggered by the device itself. What we are planning to do is : In the miniport driver, allocate a memory region using AllocateCommonBuffer() API. Split this region into N buffers of size M(max size of the data) words. Get the logical address of the buffers using the BufferLogicalAddress given by AllocateCommonBuffer(). Write these buffer logical addresses into a fifo in the device(which is memory mapped). Wheneve a packet arrives on the network, its read by the device into its internal buffer. Device takes a free buffer from the fifo and programs its dma master to trasfer data from device internal buffer to the logical address of the system buffer. It writes the logical address used inthe dma into a separate address register and triggers an interrupt. The driver's ISR, reads the address register, figures out the logical address and teh corresponding virtuall address of the buffer. Will this design work or any other dma API should be called? Is just providing tle logical address of the buffer enough for the dma master in case of a common buffer model? Thanks in advance. ~sudhir.

    - The relationship between application address space and kernel components One of my friends, who is already an experienced driver developer(and he knows how app and kernel are mapped at the overall 4G layout), insists that every application at winXP owns its virtual address space, working set(I agree with this point), so the driver code is excuted in the context of a process.So from process space perspective, kernel fault happnes at one process space/context(this is the point I don't agree with) I think it is one of the basic concpets that application runs at its own virtual space and kernel runs at their own and they are not relevant. Ntdll and system service dispatcher at kernel are the bridge that response the requst from app and dispatch the kernel components. My question here is, can my friend's point be right at some situations/ points or I'm wrong at some points? Is there any relationship between a running process space and kernel space? Please kindly point out. Thanks! -TR Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting? Tag: 75219

    - IoConnectInterrupt and surprise-removal Hello I've written a PCI function driver for a 32-bit pccard device. This device generates interrupts. The driver calls IoConnectInterrupt() during IRP_MJ_PNP/IRP_MN_START_DEVICE; it calls IoDisconnectInterrupt() during IRP_MJ_PNP/IRP_MN_REMOVE_DEVICE device. A user-mode app can open a file handle on the driver. Our test engineers have come up with the following situation: 1. Insert the pccard device. The system loads the PCI function driver and creates a DO; call it DO #1. During initialisation, the driver calls IoConnectInterrupt() successfully for DO #1. 2. Open a file handle on DO #1. 3. Surprise-remove the pccard device w/o closing the file handle. Hence DO #1 is transitioned to the surprise-remove state. The driver is not unloaded. 4. Re-insert the pccard device. The system creates a DO for this new device - DO #2. During initialisation, the driver calls IoConnectInterrupt() successfully for DO #2. 5. Now it goes wrong: whenever the device generates an interrupt, the system calls the ISR on the context of DO #1 instead of DO #2. Pretty annoying... Is this normal? The system should know DO #1 is orphanaged from the removed device, or not? And if not, why is the seconds call to IoConnectInterrupt() sucessfully? I could call IoDisconnectInterrupt() during IRP_MJ_PNP/IRP_MN_SURPRISE_REMOVAL, but this has some major consequences: the interrupt object will become invalid so the driver can't sync at DIRQL_LEVEL anymore using KeSynchronizeExecution(). Basically, the max execution level drops from DIRQL_LEVEL to DISPATCH_LEVEL for a lot of function then. Argh :-) Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting?

    - Problem with usb driver Hi, I am working on a usb driver for a custom device. This usb driver is used to recognize many different devices in the same family. My usb driver is recognizing my device correctly. Now I want to write & read some data on usb port using my application. For that I use the smae CreateFile, ReadFile, WriteFile mechanism. I get the USB port name thru WM_DEVICECHANGE message given by Windows when a new deive is inserted in the system. In my applciation, I open 3 handles for my USB port: hCom = CreateFile ("<my usb deive port name>", . . .); if (hCom) { hReadCom = CreateFile ("<my usb device port name>\PIPE00", . . .); hWriteCom = CreateFile ("<my usb device port name>\PIPE01", . . .); } This handles work perfectly for some of the devices. Data is transferred sucessfully & after that handles are closed successfully. But for some devices when I try to close the handles after read/write operation, my PC reboots. I am calling Close handle as follwoing: if (hReadCom) CloseHandle (hReadCom); if (hWriteCom) CloseHandle (hWriteCom); if (hCom) CloseHandle (hCom); I am using VC++ 6.0 as development environment for my application, and Windows XP SP1 OS. I dont know whether something is wrong with my driver or the applcation. Can you please guide me how to debug this situation. I have seen DebugViewNt traces for my driver, but didnt find anything importnat. I have enabled option to show Blue screen when PC crashes. It shows following information: STOP: 0x0000007E (0x80000003, 0x804FD7DC, 0xF8984D78, 0xF89844D8) I have seen description of this error on MSDN website, but didnt understand it properly.

    - The need to call MmProbeAndLockPages Hi, If a driver allocates memory using MmAllocateContiguousMemorySpecifyCache, does the driver need to call MmProbeAndLockPages before calling MmMapLockedPagesSpecifyCache to get a user space virtual address? I assume the pages are already locked by MmAllocateContiguousMemorySpecifyCache. Also, If a driver maps a PCI memory BAR using MmMapIoSpace, does the driver need to call MmProbeAndLockPages before calling MmMapLockedPagesSpecifyCache to get a user space virtual address?

    - Driver signing using a makecert generated certificate. We are developing an imaging system for the medical industry, containing a camera. We have developed a driver to this camera. Since this driver isnâ??t signed we are having trouble when producing the system. When connecting the camera to firewire, Windows will select the best signed driver that is the generic driver. Since we want Windows to select our driver instead we want to sign the driver with a certificate we generate ourself and add this certificate to be trusted on our system I have created a certificate, created a cat-file, signed all files using the certificate and added the certificate to the â??Trusted Root Certification Authoritiesâ?? on our system but Windows still says that the driver isnâ??t signed. Here follows a more detailed list of actions I have made: 1. The driver consists of the files: 1394camera.dll, 1394cmdr.sys, CV1394Camera.inf. 2. The line â??CatalogFile=CV1394Camera.catâ?? was added to the .inf file. 3. A certificate file and a private key file was created by using the line: makecert.exe -r -pe -n "CN=CellaVision" -b 01/01/2006 -e 01/01/2036 -eku 1.3.6.1.5.5.7.3.3 -sp "Microsoft RSA SChannel Cryptographic Provider" -sky exchange -sy 12 -sv CellaVision.pvk CellaVision.cer 4. The 1394camera.dll and the 1394cmdr.sys files were signed by using the â??signtool.exe signwizardâ??, and selecting the CellaVision.cer and the CellaVision.pvk. 5. The catalogfile was created by using the â??makecat.exe â??v CellaVision.cdfâ??. The cdf file contains: [CatalogHeader] Name=CV1394Camera.cat [CatalogFiles] 1394camera.dll=1394camera.dll 1394cmdr.sys=1394cmdr.sys CV1394Camera.inf=CV1394Camera.inf 6. The catalog file (CV1394Camera.cat) was signed by using the â??signtool.exe signwizardâ??, and selecting the CellaVision.cer and the CellaVision.pvk. 7. The certificate file CellaVision.cer was imported to the certificate store â??Trusted Root Certification Authoritiesâ?? on the system. 8. The files 1394camera.dll, 1394cmdr.sys, CV1394Camera.inf and CV1394Camera.cat were moved to the target system. (By selecting â??propertiesâ?? on each of these files and selecting Digital Signatures, Windows tells us that the signing is valid and contains a trusted certificate) 9. When updating the driver for the camera Windows still says that the driver is not signed. -- Robert Lagerstedt Technical Area Responsible CellaVision AB Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting?

    - doubt about request cancellation using KMDF Hi, in my device driver I'm forwarding read and write request from user mode application to an I/O target (USB device); Once used 'WdfRequestMarkCancelable', I use 'WdfRequestSetCompletionRoutine' function on request object and then 'WdfRequestSend'. If user mode application calls 'CancelIO', my completion callback is invoked with status STATUS_CANCELLED, but my cancellation callback is not invoked. Is cancellation callback registered by 'WdfRequestMarkCancelable' invoked only on request objects that I've created? Or this callback is invoked only while I 'own' the request? thank you Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting? Tag: 75167

    - Smart Card USB Reader (CCID) Driver Problem Hello, I develop Smart Card USB Reader device that compatible CCID class. The device has unremovable smart card, therefore interrupt pipe is not needed according CCID class specification. Regrettably the Microsoft CCID driver works incorrect with my device when the interrupt pipe is not implemented. When the device has interrupt pipe, all work correct. Does Microsoft CCID driver support CCID class devices without interrupt pipe? Does Microsoft CCID drivet incompatible CCID class specification? (Driver version 5.2.3790.2444 from 5/17/2005) Thank you in advance, Vlad (vlad.home@gmail.com) Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting? Tag: 75165

    - Question about processes I am currently using a software which I downloaded called playio. This program hooks the NtDeviceIoControl sys call and displays which process sends controls to devices. Now, I look at firefox (for example), and see interaction with following devices: ksecdd afd tcp ip netbt_tcpip_{582..... rascd My question is this, are applications really using such low level devices or are this traces a result of api's that the software uses. Thank you, please if possible explain in length. Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting? Tag: 75164

    - Port Monitor WritePort Hi all, I have a port monitor which in its WritePort does some compression, now everything works fine and the WritePort exits with a return TRUE and sets the bytes written pointer to the number of bytes wirtten in my port buffer. Now the problem is, that the spooler calls writeport again with the same data endlessly. Even when I try with different printer drivers and applications this problem still persists. The whole soluton functions with a windows terminal Service. But I dont think that this could be causing the trouble as it is the spooler on the clients side that keeps repeating calls to writeport and not ending with an enddoc. I will appriciate any help or suggestions Thanks very much. Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting? Tag: 75160

    - USB composite device coinstaller Hi Folks, I have the following problem and I'm hoping some of you have been successful on this. I am writing a device coinstaller for USB composite (miltifunction) device - 1 configuration, 3 interfaces. I am using a code based on the Toaster sample coinstaller. After I install a driver for each interface and the device shows up in the Device Manager correcly I am still getting the 'found new device' message and installation keeps asking me for the drivers... Very strange, I couldn't find the reason by reading the setupapi.log and I am hoping someone in this great forum to be able to help or at least point me to an installer sample for a multifunction device. Thanks! Dim Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting? Tag: 75151

    - TDI disconnected media This question is related to a prior thread that can be found here http://groups.google.com/group/microsoft.public.development.device.drivers/browse_thread/thread/b1515c0117407ffe/e9eb3f5114fd8849?lnk=st&q=Tdi+connection&rnum=1&hl=en#e9eb3f5114fd8849 In short I have found that my TDI driver is failing to send/receive any data when trying to enable the wireless adapter. What I noticed is that my receive handler is not receiving any data at all and the send handler is returning an error of NDIS_STATUS_NO_CABLE. I thought that that wireless adapters were treated similar to 802_3 adapters. Am I missing something here? I know that my TDI driver is somehow leaving something in an inconsistent state, but I'm at my wits end as to what. As the last thread stated this does not occur with a standard lan adapter. The driver itself is a TDI hook driver. Any help in figuring out why I'm getting this error and how to fix it.

    - UniDrv -- Plugins -- Custom Paper Sizes UniDrv -- Plugins -- Custom Paper Sizes My UI Plugin is used to create custom paper sizes. Via function "IPrintOemUI::DeviceCapabilities", I can list my "custom paper size" entries in an application's(MS Word) "Page Setup" dropdown list. When I select an entry, the appropriate "width and height" values appear in the edit boxes. However, when I go to print, none of my "DEVMODE" values for dmPaperSize, dmPaperWidth, dmPaperLength match what was shown in the UI. Instead, I get the "default PaperSize option" specified in my GPD file; which I would like to override/ignore. What am I doing wrong? Any ideas?

    - IoCancelIrp and TDI I asked for help on 1/18/06 but no one responded. Did I post incorrectly? Has anyone used TDI and IoCancelIrp? How would I go about gettin a hold of a Microsoft engineer to look at this issue? Here is the post from 1/18/06: I'm developing on a Windows XP machine using the latest DDK. Hi, I've written a com port redirector that redirects com port data over the internet to a com port device server. I'm testing with Tera Term, a terminal application, and when it opens the com port it sends a timeout of 500 milliseconds. Then I send a large file to the com port via Tera Term. As I'm streaming the data over the network, eventually the com port device server at the other end of the network cannot process the data as quickly and sends a small TCP window size in the the ACK packet. This stalls the writes for a while. Since Tera Term requested a timeout of 500 milliseconds, my timer expires and I cancel the Write IRP sent from Tera Term. I then call, from the timer expiration thread, IoCancelIrp on the Write IRP that was sent down to TDI. This causes my completion routine to fire with a Status of STATUS_CANCELLED. Now every IoCallDriver call to TDI gives me an error status of STATUS_INVALID_DEVICE_STATE (which is 0xC0000184). A network trace reveals that the PC sends an ACK with the RESET flag set in the TCP packet to the Com Port Device Server. Is there anyway to resurrect the TCP session without closing the current session down and opening another one? Thanks! Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting?

    - Errors using usbser.sys with an OHCI controller I have a USB device that is a Communications Device Class (CDC) device. I can communicate with this device via a virtual COM port by associating the device with Microsoft's usbser.sys driver. Under most conditions, this works well. However, I have noticed that, if the device is connected via a Open Host Controller Interface (OHCI) rather than a Universal Host Controller Interace (UHCI), all reads on the virtual COM port time out and, while writes appear to succeed, I don't believe the data is actually reaching the device. I have access to a kernel driver that can also communicate with this device and it doesn't experience any issues when the device is connected via OHCI. Therefore, I suspect that the problem lies in the usbser.sys driver. Are there any known issues regarding the usbser.sys driver and OHCI? Any suggestions for work arounds?

    - Backup type operations in a file system filter driver Dear all, I have posted a similar question on before asking about redirecting file IO to a different folder, i.e. modifying the target of a create request I'd also like to copy a file from one location to another when it is opened (for backup reasons). I was planning on filtering volumes and on receipt of IRP_MJ_CREATE perform the copy and then allow the Irp to continue on its way down the stack. The DDK documentation states that you shouldn't perform any complex operations in the create path, it specifies sending additional Irps as being one of the things you shouldn't do and if I am planning to copy the file at this point then I am bound to generate several... Is it safe to do this, or is there a better way? Many thanks in advance! Carly Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting? Tag: 75124

    - How to check if a spin lock has been freed or released? Hi, all, Since all the four functions NdisAcpuireSpinLock, NdisAllocateSpinLock, NdisReleaseSpinLock and NdisFreeSpinLock return VOID, how do I know if a spin lock has been freed or released in a NDIS protocol driver? In other words, what will happen if I call NdisAllocateSpinLock after NdisFreeSpinLock in DriverUnload routine? Cause a deadlock or BSOD? or maybe the driver could just run without any problem? the source code would be like: VOID MyDriverUnload(IN PDRIVER_OBJECT DriverObject) { ... NdisFreeSpinLock(&pDevExt->spin_lock); ... // NdisAcquireSpinLock and NdisFreeSpinLock are actually in another function, // but would be called after NdisFreeSpinLock NdisAcquireSpinLock(&pDevExt->spin_lock); ... NdisFreeSpinLock(&pDevExt->spin_lock); ... return; } I know it is wrong, I just want to know that how to check if the spin lock has been freed before I call the function NdisAcpuireSpinLock? Any ideas? Thanks in advance. Barry Tag: Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting? Tag: 75120

Q) Will WinXP and Win2K support to reduct I/O-port by Registry Setting?

Hello everyone,

I'm developping PCI/CardBus device driver at Win2K/XP.

I heard that there is a mechanism to reduct I/O-port by Registry Setting
like below in the device driver¡¯s INF file:

[DDInstall.HW]
Include=machine.inf
Needs=PciIoSpaceNotRequired

Wil thel WinXP and Win2K support this mechanism?

have a nice day.

Thank you.

No, Win2K and WinXP doesn't support this registry configuration.

Another point to note is that Server 2003 Gold release doesn't support this
setting but Server 2003 SP1 and Vista do.
