    - Non-device driver storage provider? I'd like to write an application that adds a virtual drive where the data comes from my private database. Basicly I'd want it to look like a USB drive, where it shows up when my program is running, and I only need some simples options, maybe not even multiple folders, and only a few files at any given time. Is the only way to do this writing a device driver? Microsoft hasn't create a mini-driver method for this yet? I know so many devices show up as drives now, my USB Memory Stick, my digital camera, my pocket PC, etc... but they haven't made it easy for an application to emulate this, and either provide hard-coded files, or files that comes from a database or remote location? Also, it doesn't have to be an actual drive letter if that is any easier, I don't need to support DOS applications or other apps that can't work with drives that aren't associated with letters (like UNC paths, or however those other virtual drives work, like the ones that show up when you use Remote Desktop and enable access to local hard drives).

    - RNDIS Device debug with the XP Hi, I am working on the RNDIS Device Firmware. I want to test device with the windows XP host . I have downloaed rndis driverkit2005(rndismpy.sys & usb8023y.sys) from the msdn site and installed on the host windows XP machine. Since my device is still under development the driver is not loaded fully on the XP. But host is sending initalization messages and my device is responding to all the NDIS message quries.But after few messages host is sending the HALT message. I could not get any debug messages on the host thorugh windows debugger. I would like to know how i can debug this problem, Any other RNDIS host driver test kit is available to test the Device. What environment (tools& kits) i can use to test the My RNDIS device during the development stage. (host RNDIS sofware which sends rndis initialization and queries messages and prints the logs) Best Regards, Ravikishore Tag: PCI to multi-switch port card Tag: 101374

    - Access denied on opening device with CreateFile I get an access denied error (error code 5) when trying to open an USB device with a CreateFile call. The program has worked before and stopped working a few days ago. It might be related to some Windows Update installation or installation of another USB device driver. I've tried different USB ports and uninstalling/reinstalling the driver, but nothing works. The driver is not digitally signed. I'm running Windows XP SP2 and the user account has full admin rights. Grateful for any tips that can help resolve this issue. -- Regards, Jesper Nordenberg Tag: PCI to multi-switch port card Tag: 101373

    - WPP Global Logger C++ Support in WDK 6000 Is the global logging session supported in WDK 6000 for C++ drivers? I have an issue where the tracing preprocessor (WPP) supplies incorrect code in the generated .tmh file when defining WPP_GLOBALLOGGER. The following is the resulting error message: error C2664: 'RtlStringFromGUID' : cannot convert parameter 1 from 'LPCGUID' to 'const GUID &'. The faulting line in the .tmh file is: Status = RtlStringFromGUID(ControlGuid, &GuidString) where ControlGuid is of type LPCGUID. Now, the signature for RtlStringFromGUID has as it's first parameter 'REFGUID' which is defined in guiddef.h as: #ifdef __cplusplus #define REFGUID const GUID & #else #define REFGUID const GUID * __MIDL_CONST #endif So what seems to be happening here is, when guiddef.h is included, the proper type for REFGUID is supplied by the C/C++ preprocessor as const GUID &. However, when the WPP preprocessor makes it's pass, it assumes it is working with the C prototype and tries to pass LPCGUID instead of const GUID & in the generated .tmh code. I suspect that this is a bug, so I wanted to see if anyone else is having similar problems. One thing I tried doing was adding the global logger to the tracedrv sample in WinDDk/6000/src/general/tracedrv/tracedrv and changing the source file extension from tracedrv.c to tracedrv.cpp. The exact same error was produced in this case. Any insight regarding this problem would be extremely useful. Thanks! -Andrew Tag: PCI to multi-switch port card Tag: 101359

    - timeGetTime versus KeQueryInterruptTime Is KeQueryInterruptTime equivalent to timeGetTime? By "equivalent" I don't mean that they return the same value or the same units; I am asking if they are derived from the same physical clock. To put it another way, if you made repeated calls to both functions over time, would you see drift between the two or would they remain in sync? I found an entry in Larry Osterman's blog where he states that "timeGetTime() reads a field called the "interrupt time", which is updated periodically by the kernel". While this is not quite definitive documentation, it does strongly suggest that the two are equivalent. Tag: PCI to multi-switch port card Tag: 101358

    - USB interrupt endpoint limitations 1) The endpoint descriptor has a minimum value of 1 ms polling period. Therefore it would seem that I can get a maximum of 1000 packets per second with each packet containing a maximum of 64 bytes of payload data. Maximum throughput then limited to 64000 bytes per second. Anyone disagree with this assessment? 2) On some computers it appears that though my USB device requests 1 ms interrupt endpoint polling the actual polling rate is 2 ms. Can anyone confirm this experience and explain it? Or better yet, tell me how to correct it. Thanks, J.R. Heisey Synaptics, Inc. Tag: PCI to multi-switch port card Tag: 101356

    - =?Utf-8?Q?Mirror_Driver_and_Mouse_Pointers?= Hi all, We are using a Mirror Driver to track window configurations. We are also running some third-party software that draws custom cursors. Whenever the mouse pointer is in its drawing window, the third party application changes the cursor set. When the Mirror Driver is active, the cursors do not operate correctly. We have duplicated this problem with the Mirror Driver Sample and Windows XP SP2. We built the Mirror Driver Sample directly from the source in the 6000 WDK, and installed it. The Mirror Driver Sample comes with a test application, â??ddmlappâ??. To duplicate the problem: > ddmlapp â??e (enable - seems to attach to the Display) Now, using Control Panel, open up the Mouse property sheets. On the Pointers tab, there is a pull down list. Select a different scheme such as 3D-Bronze and hit Apply. From that point on, the cursors behave rather strangely. The cursors donâ??t necessarily change to the new set. Also, cursor chapes may not be changed when the pointer is moved across window borders and regions that would normally change the cursor shapes (Resize, Pointer, I-bar, etc). Some seem to have effect and some do not. To restore proper operation, re-run ddmlapp: > ddmlapp â??d (disable) Now the cursor set operation appears to be normal. Cursor shapes are displayed using the newly selected set and behave properly when crossing window borders and regions. Is there something we can add to the Mirror Driver that would prevent this? Does anyone have any ideas on what I should try next? Thanks in advance for any help you can offer. Jay Tag: PCI to multi-switch port card Tag: 101355

    - IWDFIoRequest::UnmarkCancelable does not release callback object Hello, it appears as if calling IWDFIoRequest::UnmarkCancelable does not directly release the respective IRequestCallbackCancel object, which has been passed when calling method IWDFIoRequest::MarkCancelable. By debugging the driver I can see that the reference counter is increased on calling IWDFIoRequest::MarkCancelable but not decreased when calling IWDFIoRequest::UnmarkCancelable. This poses a problem, because under certain conditions I want to remove a set of objects within my driver. However, one object is not freed, because its reference counter is not zero. However, when I remove the driver, then the destructor of this object is called and in the callstack I can see that it is called by the framework. So I supposed that this is the release call for the IRequestCallbackCancel object. Why is this object not directly released on calling IWDFIoRequest::UnmarkCancelable()?

    - Installing printer driver and port monitor on vista Hi What's the best way to install a printer driver and port monitor on vista? I've looked at the Driver Install Framework, but it doesn't seems to be able to install my "virtual device". I have also tried to create a custom install application with AddPrinterDriver, AddPrinter and AddMonitor. This works fine on XP, but when run from a msi-package these functions fails with access denied on vista. I tried to set level=requireAdministrator in the manifest, but it doesn't seem to be enugh. Can anyone point me in the right direction? Thanks! Tobias Tag: PCI to multi-switch port card Tag: 101351

    - IWDFIoRequest::ForwardToIoQueue does not return immediately Hello, I am using different IoQueues for read, write, and IoControl requests in an UMDF driver. A request is first handled by an DefaultIoHandler and then forwarded to its respective queue using the method IWDFIoRequest::ForwardToIoQueue. I would expect, that this method returns immediately after it requeued the request, but instead the request is handled in the context of ForwardToIoQueue. Therefore, the call blocks until the request has been completed. This happens even when forwarding over multiple queues. Note, that these queues are configure with WdfIoQueueDispatchParallel or WdfIoQueueDispatchSequential. I suppose I could use manual queues from which I can retrieve requests in a thread separately created by my driver, to decouple the actual processing from the request. Is this the recommended way? What is the point of forwarding, if it does not return immediately? Thanks in advance for any comments or sugestions! Regards, Andre Tag: PCI to multi-switch port card Tag: 101348

    - Mini-filters, are they supported Hi, I need to make a small file spy driver in kernel mode (mini-filter, i guess) It's not possible to this in usermode (UMDF), or ?? Should regular functions be used for this (FltXXX) or is it possible with new WDF The filter should'nt do much else than report some info about create/read/write's for particular files to user mode, where it will be validated and reported back to the driver.

    - Driver Installation Framework: newbie question I am not a device driver expert by any stretch of imagination. I am just an application programmer trying to package some drivers that are required by our application that interacts with external hardware devices using InstallShield 2008's driver installation framework. I have a really dumb question. The DIF wizard asks me to point it to an .inf file (belonging to, say, a printer driver). Once done, it automatically finds all the relevant .dll and .sys files. After InstallShield packages everything into setup.exe, I run it on the target machine and the driver files do get installed correctly but my question is what exactly is the meaning of "installation"? I was kindof thinking the framework will automatically add an icon for the printer (in the Start->Settings->Printers section) and associate the .inf file with it. Is that part still need to be done manually? Tag: PCI to multi-switch port card Tag: 101330

    - Retrieving the Buffer for EvtIoDeviceControl in a KMDF Driver After the application has called the function DeviceIoControl( hDevice, IOCTL_ISOCH_ATTACH_BUFFERS, pIsochAttachBuffers, ulBufferSize, pIsochAttachBuffers, ulBufferSize, &dwBytesRet, &overLapped); the kernel (t1394_EvtIoDeviceControl function in \WINDDK\6000\src\kmdf\1394\driver\ioctl.c) retrieves the input buffer with WdfRequestRetrieveInputBuffer(Request, 0, &ioBuffer, &bufLength) ; PVOID ioBuffer; I tried to get the output buffer, so I set PVOID outputBuffer = NULL; and used WdfRequestRetrieveOutputBuffer(Request, 0, &outputBuffer, &bufLength); With this function, I have got the buffer's adress in outputBuffer. (*(PISCHO_ATTACH_BUFFER)outputBuffer shows the buffer's adress and it's the same adress as input buffer) Because I want to get some Information(pIsochDescriptor) in application, I tried to write in the outputBuffer with RtlCopyMemory((PISOCH_ATTACH_BUFFERS)outputBuffer, IsochAttachBuffers, OutputBufferLength); ( I tried also with *((PISOCH_ATTACH_BUFFERS)outputBuffer) = *IsochAttachBuffers; ) After that, I can see that the informations are written in the outputBuffer. But if I try to get the Information in user-mode (I mean after the calling DeviceIoControl function), it seems that the informations got lost (pIsochAttachBuffers->pIsochDescriptor is still zero.) Can somebody explain this? How can I bring some information from kernel to user mode (application)? thanks in advance min. Tag: PCI to multi-switch port card Tag: 101327

    - connecting to a handheld device using platform builder Hi, I have a MIPSII device with a WinCE 5.0 image flashed made by using AMDDBAU1100MIPSII BSP. What I like to know is how do I connect to this device using platform builder. This device has two serial ports, couple of USB ones and a Network port. I gave an ip address and connected a back to back cable to my host pc which has platform builder hoping that it would send bootme packets to my pc containing platform builder. I couldnot see anything. FYI the ip addresses in the host and the device are under the same subnet. I want to debug my driver and application in the platform builder just like I would do with a cepc machine. Can any one suggest me regarding this. If its not possible with platform builder, then how it is done. Thanks in advance Srinivas Tag: PCI to multi-switch port card Tag: 101325

    - How to map a UMA frame buffer from kernel to user mode Hi, I post this question again since the last subject is not clear. I'm trying to implement a method to map a reserved virtual space (created by MmAllocateMappingAddress and MmMapLockedPagesWithReservedMapping) from kernel to user mode process. From the DDK description for VideoPortMapMemory, it seems we can do UMA (universal memory architecture) frame buffer mapping as suggested in the comments. The steps are: 1. Call InitializeObjectAttributes to get object attributes; 2. Call ZwOpenSection to get the handle of the section object; 3. Call ZwmapViewOfSection to get the virtual address of the view; My question is how to set up the relation between the reserved virtual space and the section view, that's to say, how to find a section object to represent the reserved virtual space? Any expert can help to give a hint? Thanks Tag: PCI to multi-switch port card Tag: 101297

    - getting handle to device This one should be a no-brainer, I just added a dispatch routine to my bus filter driver that is supposed to return status information back. I register the interface in the AddDevice routine. This appears to be working, as I can see each instance enumerated under my GUID in the currentcontrolset\Control\DeviceClasses. The problem is after modifying the toaster examples enum application to use my GUID, I the SetupDiEnumDeviceInterfaces call fails and the last error is ERROR_NO_MORE_ITEMS. I double checked that I am using my new GUID, and that the correct number of instances of my device is in the registry. What I would like to know is how can I tell if my driver is not registering the interface correctly, or am I not accessing the interface correctly?

    - Memory leak from IoCreateDevice and driver loading Hello, We're having a memory leak problem, and it looks like it comes from Windows. Windows leaks about 50-100 bytes anytime a driver gets loaded/unloaded, affecting both the device insertion case and manual load/unload of drivers via service control manager. The problem can easily be seen by using the ddk example and pooltag utility. - Using WDK, build <wdk>\src\general\ioctl\sys driver, and install it - run the awesome pooltag utility from OSR (http://www.osronline.com/article.cfm?article=98) Steps to reproduce: - launch pooltag utility.

There are hell NVRs from different vendors that accept MPEG-4 stream, but interesting part is that these NVRs will just work with IP cameras from same vendor. Although those IP cameras also provide MPEG-4 stream. If cam and nvr is using same (MPEG-4) streaming then why we can't have interoperability ? cheers, ali Tag: PCI to multi-switch port card Tag: 101281

    - How to use make a UMA frame buffer mapping from kernel to user mod Hi, I'm trying to implement a method to map a reserved virtual space (created by MmAllocateMappingAddress and MmMapLockedPagesWithReservedMapping) from kernel to user mode process. From the DDK description for VideoPortMapMemory, it seems we can do UMA (universal memory architecture) frame buffer mapping as suggested in the comments. The steps are: 1. Call InitializeObjectAttributes to get object attributes; 2. Call ZwOpenSection to get the handle of the section object; 3. Call ZwmapViewOfSection to get the virtual address of the view; My question is how to set up the relation between the reserved virtual space and the section view, that's to say, how to find a section object to represent the reserved virtual space? Any expert can help to give a hint? Thanks Tag: PCI to multi-switch port card Tag: 101269

    - Virtual Desktops, like in *nix with Xserver Hello, I am sure you know about Virtual Desktops. UNIX had them for about 20 years. There are some implementations for Windows too, even a Microsoft one, but for some reason they all suck. The primary reason is that they provide only an emulation of the real stuff -- basically they minimize one set of applications in one desktop, one set in another and so on -- they aren't real Virtual Desktops. The best implementation so far seems to be Virtual Dimension, but it still sucks, mainly because there are application that make hacks in the GUI, ignoring any recommendation. The main issue, is that all this are emulations -- Windows doesn't have the capability for Virtual Desktops. That is why I have thought of implementing it via a driver! I am not sure what the best way is -- I need to make it hardware independent -- that is -- it should not matter what video card you use. I think I should implement a filter driver somehow, but still don't know what exactly it should do -- I am asking here for suggestions. Thanks in advance.

    - USB Host Controller and USS Hub Hi All, I am a windows driver developer working on USB. I have few questions on USB. 1.Role of Host Controller driver/hw and Root Hub driver/hw in enumerating a newly connected usb device. 2.How does usbhub.sys know the device connected to roothub? Does Host controller hw/driver informs it? 3.Is there any difference in device detection when connected to the root hub port and the externel hub port(usb hub connected to the root hub). I suppose same driver is loaded for the root hub as well as external hub. 4.Does USB Host Controller use any ISR for detecting the device connected to the root hub? If so what about the device connected to the external hub. 5.Will (Host controller? or Hub?)keep polling by itself on all the visible ports for the device arrival? If you know, where all this information regarding the Host Controller and Hub exists, please give the references to me. Exact sequence of events happening, i.e device detection, address assignment and pdo creation by the bus driver(usbhub.sys) and polling mechanism. Thanks in advance, Vivek.

I researched it, and on both drives did "disk cleanups", "file compressions", uninstalled programs no longer used, defraged both drives, deleted all "system restores" with exception of current date. I copied my 1 system restore to disks. Can I now go in and delete all the files on D drive. HP support advised me to un-install my OS and reinstall. Will that work???

    - MmProbeAndLockPages for user buffer pointer I have some doubts on mapping user pointers in the kernel - Lets say I have to have a user pointer passed within a struct as input to deviceiocontrol. I need to read stuff from this user pointer location. So within the driver dispatch handler I do the foll: mdl = IoAllocateMdl(userBuf, userBufLen, FALSE, TRUE, NULL); // Probe and lock within a try except loop MmProbeAndLockPages(mdl, UserMode, IoReadAccess); ASSUMING I never send the userBuf down to any other lower driver, dpc or completion routines - can I read from userBuf pointer directly within the dispatch handler ? .. Or do I still have to call MmGetSystemAddressForMdlSafe and only access the returned virtual address ? I guess I am not entirely certain if the userBuf virtual address is guaranteed to be valid with just doing a ProbeAndLock. Is there any way this virtual address could become invalid ? Also - can the contents of this userBuf be modified (say by another "bad" thread in the calling process) while this userBuf is locked for read in such a manner ?

    - BREAK_RESERVATION returning STATUS_INVALID_DEVICE_REQUEST Would anyone know why IOCTL_STORAGE_BREAK_RESERVATION would return STATUS_INVALID_DEVICE_REQUEST ? This is issued using IoCallDriver() in my driver, the request originates from the MS cluster service I believe. I've checked the values in 'Irp->AssociatedIrp.SystemBuffer' as per the STORAGE_BREAK_RESERVATION_REQUEST structure, they seem correct. If I issue the exact same IOCTL synchronously to the same LUN / device from within my driver it completes without any error. Anyone got any ideas, suggestions or clues ?

    - Retrieve USB_DEVICE_DESCRIPTOR only once from USB-device Hi, I try to validate my USB-device by checking its descriptor entries. Thus I added the following code to the IRP_MN_START_DEVICE routine: UsbBuildGetDescriptorRequest(...); IoBuildDeviceIoControlRequest(IOCTL_INTERNAL_USB_SUBMIT_URB,...); This works so far, BUT analyzing the USB-transfers after plugging in the device I get the following USB-stream: 1. SetAddress() 2. GetDescriptor(Device) 3. GetDescriptor(Configuration) ... Now my Driver starts and I get another GetDescriptor(Device). Is it somehow possible to get the USB-descriptors from the lower USB-Bus driver without resending a GetDescriptor-request to the USB-device? Or is it some odd behavior of the Host-Controll-Driver?

    - possible bug in e100bex ndis DDK 6000 sample ? The function NICReturnRFD(Adapter, pMpRfd) pulls a HW RFD corresponding to pMpRfd from the linked list and adds it to the tail. While sofware links will be ok, the HW RFDs link will be broken because, pHwRfd->RfdCbHeader.CbStatus = 0; pHwRfd->RfdActualCount = 0; pHwRfd->RfdCbHeader.CbCommand = (RFD_EL_BIT); pHwRfd->RfdCbHeader.CbLinkPointer = DRIVER_NULL; AND // Link it onto the end of the chain dynamically pHwRfd = pLastMpRfd->HwRfd; pHwRfd->RfdCbHeader.CbLinkPointer = pMpRfd->HwRfdPhys; pHwRfd->RfdCbHeader.CbCommand = 0; WILL only fix the CURRENT and NEXT links and NOT the PREVIOUS HW RFD link. There should be a way to fix the previous HW RFD link pointer also. something like pPREV_RFD->RfdCbHeader.CbLinkPointer = PENULTIMATE_TAIL- >RFD_PA This code luckily works as long as pMpRfd in NICReturnRFD(Adapter, pMpRfd) is the HEAD ENTRY. In MpHandleRecvInterrupt ( ... ) it was a lucky case and in MPReturnNetBufferLists(...) and a couple of other places it looks like a BUG. Can some one clarify? I have attempted a pictorial description of the bug hw_rfd1 -> hw_rfd2 -> hw_rfd3 will become 2 sets hw_rfd1 -> hw_rfd2 AND a hanging hw_rfd3 -> hw_rfd2 !! because of bad linking of pHwRfd->RfdCbHeader.CbLinkPointer thx ugk Tag: PCI to multi-switch port card Tag: 101225

    - Virtual Cdrom Driver Port to Vista Dear all, I have a Virtual Cdrom Driver, it can emulate an ISO file on network drive as a Cdrom.It works well on Win2k/WinXp/Win2003. I need to port it to Windows Vista, but it can't work well. In this driver, I use DO_DIRECT_IO as I/O flags, use MmGetSystemAddressForMdl( Irp->MdlAddress) to get current Mdl Address, and use ZwReadFile to read data from Virtual Cdrom. I also use MmGetMdlByteCount(Irp->MdlAddress) to get the length of system assigned buffer for Mdl. On Win2k/Xp/2003, ZwReadFile can be executed normally. For the first 3 executed times for ZwReadFile, the length of Mdl buffer is 2k, from the 4th time of executed ZwReadFile, the length of Mdl buffer is 4k. But on Vista, ZwReadFile can be only executed 3 times, the length of Mdl buffer is also 2k for these 3 times. For the 4th executed times of ZwReadFile, the Mdl buffer is 32k, ZwReadFile is blocked and can't be executed anymore. Also the driver is blocked. Can anyone give me a hint for this issue?

Is their any vendor solution for this product ?

How can I write such driver myself , should I base on network adapter driver ?

Another question , is their any difference between PCI and PCIe ?

Thank you .
