    - Camera Custom Property Page Sample code Hi, Does anyone know which CD-ROM or DVD contains property page sample code released by Microsoft dated 1998. I have searched platform SDK 2000, 2001, and 2005, but nothing comes up. This sample code will generate a camprop.ax file that will be installed and worked with a WDM driver. I believe one of file name is camprop.cpp. Tag: Is there any difference in ftp xfer done via Internet explorer and ftp xfer done when window opened in windows explorer? Tag: 91588

    - Toaster Filter driver Hello guys, I have a question. I have modified some of the KMDF toaster sample filter driver from WDK6000 and tried to install this to one of usb function driver to see if I can get the right IRPs from it. But unfortunately I couldn't make it work when I install it with the INF file coming with the sample code. How can I modify this INF file to make it sit on top of one of the USB devices? or is there a simple way to do it manually as use to be with the WDM?? I used to make a registry key "UpperFilters" in the designated device and disable/enable the device manually, then it was working fine. How can I do this with the KMDF? Should I always use the INF to install it? even to the filter driver? Thank you.

    - SetupDiGetClassDevs couldn't detect medium changer hello all, I am workinging on SPTI to access my SCSI medium changer (Jukebox) with blueray drive. Now I have trouble to detect medium changers. I can see "unknown medium changer" showup in Device Manager. code like this: guid = (GUID*)&GUID_DEVINTERFACE_MEDIUMCHANGER; // Get device interface info set handle for all devices attached to system HDEVINFO hDevInfo = SetupDiGetClassDevs(guid, NULL, NULL, DIGCF_PRESENT | DIGCF_DEVICEINTERFACE); ...... while ( SetupDiEnumDeviceInterfaces(hDevInfo, NULL, guid, dwIndex, &devInterfaceData)) { .......... if( SetupDiGetDeviceInterfaceDetail(hDevInfo, &spdid, pspdidd, dwSize, &dwSize, &spdd)) { HANDLE hDrive = CreateFile(pspdidd->DevicePath, 0, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, NULL, NULL); ............................ } } It always return 0 item when doing enumeration. I also tried createfile on "\\.changer0". none of those work. does anyone have any idea?

    - When exactly USBD_STATUS_ISO_NOT_ACCESSED_BY_HW is reported ? Hi, To give you a little background of my query, We are developing a USB Host Controller and it is expected to work with the standard HCDs (usbehci / usbohci) on Windows XP SP2. All the devices, except high-speed isochronous (camera), work properly. With the HS camera (logitech) we see that enumeration is all success, but we don't see any picture. Upon debugging further we observed that the client driver of the camera gets all the packets back with the status 'USBD_STATUS_ISO_NOT_ACCESSED_BY_HW' ! The URBs are posted with USBD_START_ISO_TRANSFER_ASAP flag set. On the bus however we see the Isoch transactions going (and device responding to it). As very little information is available on this, I was curious as to when the USBEHCI resorts to this return value. Exactly what causes it to deduce that 'the controller did not access the TD asocated with this packet' ? Any pointers will be greatly appreciated. Thanks and Regards, Abhijit Tag: Is there any difference in ftp xfer done via Internet explorer and ftp xfer done when window opened in windows explorer? Tag: 91584

    - 1394 Driver Install Prompts When Only Chip ID Differs Hi All, Is there any way to prevent the user from being prompted for .inf and .sys files when a second or more 1394 device is plugged in of the same type? e.g. When only the Chip ID of my device is different? It seems Windows should recognize when it sees a second 1394 device of the same manufacturer and device name (but only the chip id differs) and load the driver for that device. It seems that this can be done since I'm not prompted, for instance, when two different USB memory sticks are plugged in of the same model. Thanks in advance. As always, any help is appreciated.

    - Network adapters immediately re-detected/installed after uninstall Can anyone explain why, when uninstalling a network adapter class device, the OS immediately reinstalls it. Sometimes even while the uninstall is still in progress? Or can anyone confirm that this is actually a bug in Vista? It doesn't appear to happen with any other device class - just network adapters. Uninstalling any other class makes it's instance disappear from Device Manager. With network adapters though, it looks like there is a PnP refresh and it re-detects the hardware.

    - Filesystem overlay (poor mans unionfs) Hi there. For a legacy application that expects all its customization (.dlls, mostly) in its working directory and because I need to constantly switch projects (which involves "copy the working directory, replace it with another one and restart") I searched for a kind of unionfs[1] for windows, which would allow me to create a logical view on the application directory which includes external directories as neccessary. Sample: C:\MyApp\Bin\ C:\MyApp\Projects\Foo\ I'd like to map all file requests that would fail for the Bin to check another directory again. Being new to this stuff (and doing it out of lazyness, since the process described above sucks) I'd love to hear that this barely involves dispatching IRP_MJ_CREATE? My current idea would be to deploy a minifilter which does the following steps in the PreCreate event: - Check if this request wants a file inside of my Bin directory., else ignore the request - Check if the request is readonly (no create file, no append), else ignore the request - Check if the requested file exists (ZwFileOpen?) and - ignore the request if the file exists - redirect the request to the overlay directory otherwise (setting the filenameinfo and marking the request as dirty) Since I'm bloody new here: Can anyone comment on obvious mistakes? Is this too hard for a beginner's (talking about drivers here) task?

    - print driver default settings strategy in 2003 server and xp Hi, in a point and print relationship between printQ on 2003 server and xp client, I set up "advanced / printings default" in the print driver option on the server. When the customer install (with point and print method)the printer on the XP, the default setting in the driver match the printQ configuratin of the server. Everything seems ok I use this method for setting up a global print strategy (like force duplex and black and white printing by default).But when the user changes default printing options locally, system keeps this setting as default. I'm looking for a way to allow the user changes setting "on the fly" when printing, but forbid permanent local settings change. In other words, when user opens its application again for printing, default printings option should match the server one. Thanks in advance for your help.

    - SDDL string in NdisRegisterDeviceEx() Hi all, further: Running with an SDDL string of "D:P(A;;GA;;;SY)(A;;GA;;;BA) (A;;GRGW;;;BU)(A;;GRGW;;;WD)" and calling NdisRegisterDeviceEx() retruns STATUS_SUCESS, In WinObj I can see the device, and its security is set to: System, Administrators and Everyone: Delete and Query State are checked in the Allow column, everything else is unchecked. Restricted, Query State is checked in the Allow collumn, everything else is unchecked. What ever I set the SDDL to this doesnt change, which is odd. With the result that I cannot open the symbolic link from user land. (My dispatch handler is _not_ getting hit) This is a Miniport ontop of a multifunction USB bus driver (ours). Is there any reason why changing the SDDL doesnt work? Is there any kind of inherited security from the lower bus?

    - bulkusb sample with DTM test Hello, I am new to DTM test. I use Vista DDK's bulkusb sample to transfer MP3 files between PC and Handset. The Handset just has a bulk-in and a bulk-out pipe, and our purpose is just to transfer MP3 files. It works on Vista. Now I use DTM to test it, the .inf shows it belongs to USB class (just like bulkusb.inf). I use usb cable connect handset and pc. And I choose WDK\ConfigureUSBController in MCU Ploicy tab to start DTM test. And then I create a submission(x86 Vista) to run test items(it shows 7 items on DTM Studio) and always failed immediately after I schedule these jobs. All I want to ask are: If the .inf must has a CAT file first and I must add a CatalogFile=XXXX.cat and can not give it a blank CAT file? If I should make a CAT file first and then can do other test items, or they will all fail? Should it must connect through a usb 2.0 HUB? I had test HCT before, it seems simpler than DTM. I am not sure about DTM whether something important that I must to do and I forget to do. Please help me. Thanks.

    - Poor DMA read rate I have a PCI device (32-bit/66MHz) that has a really poor DMA read rate (host to device) that is somewhat decent in one machine (59MB/s) but is really poor in another machine (4MB/s). The performance in the second machine is equivalent to directly reading memory from the host 4-bytes at a time. The DMA write rate (device to host), however, is roughly the same in both machines and close to the theoretical (262MB/s). The device acts as the master for both reads and writes. I have a limited knowledge of the details of the PCI bus. Does this look like an issue with the PCI bridges getting configured differently, resulting in the read transactions being terminated prematurely? I have access to a PCI analyzer and will be setting that up as soon as I have access to the machines again, but I was wondering if this looks like something obvious to someone more knowledgeable about the PCI bus. Also, are there any parameters that can be tweaked to improve the read DMA rate overall? I realize that this is probably highly dependent on the DMA engine on the device itself.

    - Help!! Out of the Pot and into the Driver Fire I need some help. I have been thrown in front of a bus at work. We are having trouble fully testing our network enabled apps for their resilience to the effect of lag and dropped packets and I got tagged as the lucky developer to find a solution. As usual, we can't buy anything; but, in this case I cant find anything that would work anyway. I need to create a small app that will allow me to catch UDP/TCP packets going up and down the stack and hold them for a resizeable amount of time to "fake" lag for our app. I also need to be able to throw out packets based on some known frequency and unknown (psuedo-random). Of course, None of us here are Windows driver developers, but from the research that I've done, it looks like I will need to make a Intermediate NDIS driver and/or Filter driver. I am pretty sure I can't do this project in VS 2005, and I need the WDK....Right? Are there any other things that I will need before I install the WDK? I have been studying the MSDN literature on NDIS intermediate/filter drivers, but I am not real sure where to go next. Thanks a billion for any help.

    - USB Selective suspend support by Vista? Our device is a usb 1.1 low speed device with remote wake up capability. and it runs with the Vista in-box hid driver. it also passed USBCV suspend/remote wake up test, Well, after choosing maximum power saving policy in the Vista, we still can not obeserve the driver would send out the "set feature" command to enable the remote wake up function in our device. The deivce keep working on D0, and was not able to go into a power saving state. ""========= Per the ..http://msdn2.microsoft.com/en-us/library/ms793200.aspx In Microsoft Windows XP and later operating systems, the USB core stack supports a modified version of the "selective suspend" feature that is described in revision 2.0 of the Universal Serial Bus Specification. The USB selective suspend feature allows the hub driver to suspend an individual port without affecting the operation of the other ports on the hub. Selective suspension of USB devices is especially useful in portable computers, since it helps conserve battery power. Many devices, such as finger readers and other kinds of biometric scanners, only require power intermittently. Suspending such devices selectively reduces power consumption. More importantly, as long as any USB device remains powered, it will prevent the system from entering deeper sleep states, such as C3. The Windows selective suspend behavior is different for devices operating in Windows XP and Windows Vista. ""========== Once the device keep working on D0, it would prevent the CPU enter C3, it would result in the whole system consume more power.. Does anyone knows 1. The in-box HID driver in Vista support seletive suspend feature? 2. If yes, what's the requirement for arming the command to the device?

    - Multiple MiniportMessageInterruptDPCs on the same CPU In the following scenario, does NDIS call one MiniportMessageInterruptDPC per MSI message or just one DPC call? 1. The driver uses two MSI-X messages. 2. MiniportMessageInterrupt always sets QueueDefaultInterruptDpc to TRUE and returns TRUE. 3. The device sends one MSI message and interrupts a CPU. This causes a DPC. 4. While the last DPC is either running or is scheduled to run, the device sends a different MSI message and happens to interrupt the same CPU. Is this always going to result in another DPC because the interrupt is due to a different MSI message? Thanks...

    - 1394 Debugging - So Close - Need Help I've set up my host and target machines for 1394 debugging.

I've read the documentation that warns to disable the target 1394 host controller before debugging with the caution "Be careful not to accidently disable the 1394 net adapter instead". The problem is, when I disable the 1394 host controller on the target, the 1394 net adapter disappears from the listing and thereby not allowing a debug connect at all.

    - IOCTL_SCSI_PASS_THRU commands in limited user mode Hi, Currently I am using IOCTL_SCSI_PASS_THRU commands in admin user mode, when logged in limited user mode I am not able to send IOCTL_SCSI_PASS_THRU commands to an USB device. The reason is Create file will fail due to Generic_read/Generic_write which is not available in limited user modes, and IOCTL_SCSI_PASS_THRU needs these options in DeviceIOControl. As I am working with USB Mass Storage device using usbstor.sys mass storage driver is there a method that would send same commands through USB end points or pipes. Also I found IOCTL_USB_USER_REQUEST which has USBUSER_PASS_THRU option but I could not locate any sample codes, i guess these are not documented. What I am trying to do is to send an vendor specfic command to an USB Mass Storage deivce.

    - machine hanging after reboot when enabling driver verifier When enabling the driver verifier and rebooting the machine (done automatically for some tests by DTM), the machine is hanging during the reboot. I can reproduce the problem also by doing the same thing manually (without DTM). I have Windbg attached and it seems the system is hanging at the very beginning: it seems the driver under test is not loaded yet, the last messages from windbg are "kernel debugger connection established", some stuff about symbol paths and "system uptime: not available" as last message. I'm only able to break into the debugger until after a very long time (more than 10 minutes). The strange thing is that I do not see the problem on all my test machines. I'm currently using 2 machines: the one which has the problem is a single-processor machine, the other one, which is a multi-processor machine, does not have the problem. Another difference between them is that the one with the problem has both XP and Vista installed on it while the other has only Vista installed. Both are 32-bit machines. Has anybody already seen this problem before or does anybody have suggestions to debug this problem?

    - inf update Hi, I made a USB WDM driver. I am trying to make an update on my driver. Every time I use the update driver the system crash. And I can't find anything wrong. I have to physically remove first the old driver and reboot I was wondering if there is anything in INF to specify the removal and/or the replacement and/or reboot of the system. Thanks.

    - Tcpip.sys bug: FTP Upload. MiniportHalt isnt called untill it has returned all the outstanding sends. So, set up an FTP upload, then do a safe remove. Result, underlying USB bus driver gets the query remove and retuend INVALID_DEVICE_STATE for the Ndis miniport driver writes, but the miniport drivers Halt routine doesnt get called and the device doesnt get unloaded, hanging the PnP manager with device manager showing the device stil present. (You can tell the PnP manager is hung because an inserted USB stick isnt recognised). Via an applet and an IOCTL interface, the Ndis driver can be told to stop, whereupon it cancels all its send packets with a status of NDIS_STATUS_MEDIA_DISCONNECT. After this has hapened the miniport halt function does get called. So, from looking at the DDK: The PnP Manager issues an IRP_MN_QUERY_STOP_DEVICE request. On receiving this IRP, NDIS calls the ProtocolPnPEvent function of all protocol drivers that are bound to the adapter. In this call, NDIS specifies an event code of NetEventQueryRemoveDevice. If a protocol driver fails the NetEventQueryRemoveDevice event by returning a failure code from ProtocolPnPEvent, the PnP Manager might ignore the failure and subsequently succeed the IRP_MN_QUERY_STOP_DEVICE request (but it looks like it doesnt) ... After all protocol drivers are unbound from the NIC, NDIS calls the miniport driver's MiniportHalt function. So, it looks like tcpip.sys is failing the NetEventQueryRemoveDevice because it still has outstanding sends with the Nic driver, but the Nic driver cant complete them till its Halt function is called. Chicken...egg...chicken...egg. This is on XP SP2. I wonder if its 'fixed in Vista', like selective suspend ; ) Tag: Is there any difference in ftp xfer done via Internet explorer and ftp xfer done when window opened in windows explorer? Tag: 91474

    - DIFx and virtual device drivers... I would like to use DIFx to install some virtual device drivers. Since these are virtual drivers I have to create the device instances manually. Is there a recommended way to do this with DIFx? DIFx appears to require a real device before it will create an instance. Is there a DIFx way to do this or should I use the SetupAPI and create the device?

    - How user mode drivers handle client application crash? Hello, I write a user mode USB driver which serves overlapped ReadFile requests from the client application. There will be exceptions in the driver when the client application crashes(or is closed by the Task Manager). Is there any special requirment for the user mode driver to handle this situation?

    - Parallel Dispatching in KMDF drivers I have a PCI hardware with two communication channels. (A and B) Only DeviceIoControl() is used to communicate with this hardware, because there are In- and Outdata for each IRP. In NT4.0 driver I use the standard-queue for Type-A IOCTLs and a user-defined-queue for Type-B IOCTLs NTSTATUS MyDeviceControl(...) { ... switch(pIoStack->Parameters.DeviceIoControl.IoControlCode) { case IOCTL_MY_SIMPLE: // read some bits from hardware and complete IRP ... pIrp->IoStatus.Information=... pIrp->IoStatus.Status=... ntStatus=STATUS_SUCCESS; IoCompleteRequest(...) // no queue used break; case IOCTL_TYPE_A: ntStatus=STATUS_PENDING; IoMarkIrpPending(pIrp); IoStartPacket(...) // the default queue break; case IOCTL_TYPE_B: ntStatus=STATUS_PENDING; IoMarkIrpPending(pIrp); MyAlternateStartPacket(...) // my second queue break; ... } ... } -------------- Now I want to port my driver to KMDF. But I can define only one separate queue for Read, for Write and for IoControl. My Problem is, that I need two queues for IoControl like in my NT4.0 driver, because two User-Mode threads are communicating with my hardware (one thread with channel A, the other with channel B) Question 1: Is it possible in KMDF to return the IRP without using a queue (like IOCTL_MY_SIMPLE) Question 2: Can I direct my IRPs into different queues in KMDF? EvtIoDeviceControl is called for all types IOCTLs. (IOCTL_TYPE_A and for IOCTL_TYPE_B) Thanks Jacques Tag: Is there any difference in ftp xfer done via Internet explorer and ftp xfer done when window opened in windows explorer? Tag: 91437

    - Print Monitor Needs to Access Interactive Services I have a print monitor that is installed for a custom Postscript printer driver. This print monitor needs to display a screen asking the user to name a file and select some processing options during the call to LcmStartDocPort. It also invokes a COM object that display several interactive screens to process the file during the call to LcmEndDocPort. The printer driver and monitor installs and runs on OSes Win2K and up. It also installs on Vista, and it will properly interact with the user and process files as designed. However, on Vista the OS intercepts the dialog boxes and displays a dialog titled "Interactive Services Dialog Detection". The message is that "The program [my port monitor] may need information or permission to complete a task." When the user clicks OK, the dialogs are displayed. My questions: 1. How can I properly set permissions (programatically, during the installation) on the port monitor so that it can interact in the user session without the OS intercepting the dialog boxes? 2. Do these permissions need to be applied to the port monitor (a dll) or to the spooler that invokes it?

I tried to use CertOpenSystemStore() and CertEnumCertificatesInStore() APIs. Some certifications stored in local computer, but I sometimes get no certification. I don't know what the reason is.

For example (task manager)!; And some of the folder security gets changed (you canâ??t access folders that you were allowed to access). And when you restart the OS it will not restart!!!

    - save string functions at IRQL > PASSIVE_LEVEL? I'm porting a big old driver to KMDF. I use some strcat()/strcpy()/sprintf(), often for internal diagnostic messages. They are now deprecated, and the recommended kernel mode replacement RtlStringCch*() functions are bound to PASSIVE_LEVEL. So what is your meaning about the best solution: Leave everything as it is and disable compiler warnings ? Or write my own strcpy_s()/strcat_s()/sprintf_s() ?

Hi,

When I goto an ftp site in Internet Explorer, I see an option Page->"Open
ftp site in Windows Explorer".
I see that throughput drops and it takes mroe time for xfer when I choose
to use 'Open ftp site in Windows Explorer".
Are there any differences between this option and the regular ftp interms
of app behaviour?

Regards,
