    - API to rollback driver? Does anyone know of a way to invoke the "Roll Back Driver" functionality of Windows XP programmatically? I've searched the MSDN docs and the web to no avail... Anyhow, I'd like to invoke a rollback during an uninstall of a "custom" driver, so that we can revert to the default driver when uninstalling ours. Thanks in advance, Lee Tag: Class GUID issue Tag: 38376

    - Maximum StrMini Driver Size?? I am developing a stream class mini driver based on usbcamd. Today I ran into an extremely odd BSOD that I initially thought was related to some memory management code that I had added. It turns out that the problem is that I added code. I have reached the state where the following will take the driver from functional to non-functional. int i for(i=0;i<1;++i){} I can add this, or equally useless code in a variety of different functions (none of which are called) and cause this error. The BSOD message is about a page fault in the non-paged area caused by ks.sys. It occurs when I attempt to render the capture pin on the filter. The driver can be loaded and unloaded as many times as one likes without error. I am wondering if this can be related to SRB_PAGING_OUT_DRIVER? I noticed that the INF file (intelcam) I copied does set PageOutWhenUnopened registry setting. Is it possible that enabling this can cause this error or is there some other possibility? This is running on XP Pro SP1. Regards, Tom Udale Tag: Class GUID issue Tag: 38374

    - Sound Capture Hi, I have a problem.... actually it is a thing to do on my list, and I wondering if anyone can give me a hint or two on where to look for tackling it. Well, all I need to do is to intercept and capture sound (wav or raw doesn't matter) that only a certain application generates opposed to whole system (all apps.). The app. uses none of the fancy directx stuff, just plain win32 APIs (MCI I think) Any thought on how should I begin looking for this solution?

    - Device Extension for NDIS miniport driver I am writing a NDIS miniport driver. From DDK documentation, I was told to use NdisRegisterDevice instead of IoCreateDevice to create a device object. However, the same documentation also says that the device extension for an object created with NdisMRegisterDevice is reserved for use by NDIS and cannot be used by the driver. I want to modify the device extension to store any state status and information. How can I do that? Thanks, Billy. Tag: Class GUID issue Tag: 38370

    - SetupCopyOEMInf - avoiding prompts during install I have a new driver install and an old driver install that use different source media locations. I have been using SPOST_PATH for the OEMSourceMediaType when I call SetupCopyOEMInf. This is leading to setup problems because the old INF is selected by SetupAPI during install. This INF points to an installation directory that does not exist and the user is prompted for the correct location of required files. I think the root of this problem is that the PNF has to old source media information. Should I call SetupCopyOEMInf with SP_COPY_REPLACEONLY copy style to update the old PNF if it exists and then call it again with the SP_COPY_NOOVERWRITE copy style to copy it sure the PNF has the current source path info (if needed)? I'm installing an IM driver on 2000/XP. Thanks, Shawn Tag: Class GUID issue Tag: 38364

    - Hardware ID in win 2000 and UpdateDriverForPNP My .inf has an entry for that says _01 %xyz.DeviceDesc%=xyz.Device,USB\VID_xxx&PID_yyy I am trying to install the driver for the device for the case where the device is plugged in but the Add New hardware wizard was cancelled by the user. Now, if I pass the HWID "USB\\VID_xxx&PID_yyy", updateDriverfor.. fails with 20B (no_such_device) I think. Then if I change it to "USB\\VID_xxx&PID_yyy&Rev_0001" (which I know from the registry whenever I install this successfully in the nice ol' plug device after software installation way) AND also change it in .INF, my updatedriver.. succeeds and device is shown working properly with the correct name in device manager. So my question is, what is that Rev.. thing? is it like a hardware revision? if so, I would not know every possible revision number in advance and would like to keep it generic for the device? How do I achieve that? What is the correct entry in .INF and correct HardwareID to be passed to the function updatedriver.. Thanks for your time. Tag: Class GUID issue Tag: 38363

    - Child Display Driver... Hi, I want to implement a WDM Child Display Driver and request I2C interface from display driver which I am going to use to send the DDC/CI data to Monitor. One option was to have WDM child driver to miniport but I am exploring this possibility. Is it possible to make a WDM driver a child driver to main display driver and how do I specify that this is child driver of display driver so that system and display driver can understand this ? Any help in this regard will be appreciated.. Vishvesh Tag: Class GUID issue Tag: 38358

    - What's the rule to call IoCompleteRequest for power Irp? I understand when should call IoCompleteRequest for PnP Irp. For Power Irp, it seems have different rule. I am confused, I don't know when I should call IoCompleteRequest for power Irp, when should not. For example, bulk usb sample code of XP DDK. In set device power state process, IoComplete routine of power Irp calls IoCompleteRequest to complete Irp when power up. However, IoComplete routine doesn't call IoCompleteRequest when power down. Why it needn't call IoCompleteRequest? What's the rule to call IoCompleteRequest for power Irp? Can anyone tell me? Best Regards Jackal Huang Tag: Class GUID issue Tag: 38354

    - Help on Win2k and USBD_STATUS_DEV_NOT_RESPONDING Hello Everyone, I have written a NDIS-WDM (USB) driver. I ran the NDISTest on Windows XP. There was no problem. Then I used (ported) the same driver on Win2K (by setting NDIS50 instead of NDIS51). Surprisingly, I am getting a strange problem. When I run heavy traffic tests (like 2c_PerformanceProfile and 2c_SendRecv1), I get a strange error in the middle of the transfer. I get STATUS_DEVICE_DATA_ERROR in the IRP Status and USBD_STATUS_DEV_NOT_RESPONDING in the URB Status. But the device is connected and running. I tried doing RESET_PORT at the error condition. But it does not help. Also, when I remove the cable also, I don't get STATUS_DEVICE_NOT_CONNECTED in Win2k (like I get on WinXP). Instead I get STATUS_DEVICE_DATA_ERROR (and USBD_STATUS_DEV_NOT_RESPONDING). How can I handle the conditions? Even though the device is connected and working, I get USBD_STATUS_DEV_NOT_RESPONDING and when the device is not connected also I get the same error. There is no difference in the errors. Since mine is a NDIS-WDM driver, I don't get SURPRISE REMOVAL event on Win2K (as I get on XP). So, I cannot detect the surprise removal also. I have to wait for the MiniPortHalt to be called which does not happen until I stop the USBD IN/Read transactions. If I ignore the first error of USBD_STATUS_DEV_NOT_RESPONDING, I get ENDPOINT_HALTED error in the subsequent IN/read transactions. I know at least one of you might have faced the same/similar problem. Can anyone please help me in having a work-around for this problem. If I am doing something wrong in my driver, please let me know so that I can correct the same. Thanks in advance for the great help. Best Regards, GNRaj Tag: Class GUID issue Tag: 38350

    - Device object creating in 2003 Hello, I am making some device driver for DVD media. But I have trouble for DVD multi-drive that can support DVD-R/RW, DVD- RAM media at same time. So I need change it's device type depending on media. Also, I want to create DosDevice which will be a mount point of media. ( This works good in Windows 2000 ) What I am trying to do: 1. Change device type from FILE_DEVICE_DISK to FILE_DEVICE_CD_ROM or reverse. 2. Create virtual driver letter( ex, z:\ ) which is symbolic linked to '\Device\xxxx'. * basically both 1 & 2 are working good in windows 2000, but not in windows 2003. Where I am at: 1. When the system boots up, I create Device node with FILE_DEVICE_DISK. When a DVD-ROM media inserted, delete that node and create new device node with FILE_DEVICE_CD_ROM as same device name. ( In case of DVD- RAM media, use it as it is. ) The deletion and new creation device node returns success. But when I try to get File system using NtQueryVolumeFile, the process is hang. I quess the device type is not changed. 2. When I got some ioctl, I create 2 device nodes. One is \Device\xxxx with FILE_DEVICE_DISK and the other is \DosDevice\z:. And I did symbolic link both. Here, I got success return value for all step. But I cannot look up \DosDevice\z: even if I can see \Device\xxxx.( with WinObj.exe ) The data I/O to z: works good. But I can't see z: drive in window explorer. * But when I make a windows service application which do as same step of #2, the service application can create \DosDevice\z: and z: is visiabl in window explorer. Both 1&2 device driver is made of LEGACY type not PNP. Let me know if you need any more details. Thanks. Tag: Class GUID issue Tag: 38346

    - Triggering DrvNotify calls in multi-monitor environment I have a multi-monitor environment in Windows XP (both primary and secondary monitors active) and am trying to determine what I can do in the graphics driver of the secondary to trigger a DrvNotify call to the primary's graphics driver. DrvNotify calls are made to both primary and secondary if the origin of the secondary changes. But all I want to do is trigger the primary DrvNotify call without doing something drastic like changing origins. Thanks, Armin Tag: Class GUID issue Tag: 38343

    - Problem in Resuming the machine after suspend I have a USB2.0 video capture device connected to a laptop. If the video capture device is connected through a USB 2.0 hub, then the machine resumes properly from a suspend.

    - Two similar devices in Device Manager after preinstall Hello, What I am trying to do: Preinstall a driver so that a device that is already connected (but not gone through/cancelled the found new hardware wizard screen) works without disconnect and reconnect. (since I cannot make animations showing "plug it in now" :) ) Where I am at: I know the hardware id of the device and I am using a code very similar to install.c in the DDK sample for installing the driver using UpdateDriverForPlugAndPlayDevicesSoThatTheUserDoesNotHaveToGoThroughTheFoundNewhardwareScreen function. It seems to be working, well, only partially. I am on w2k, and have to use the SetupDiGetINFClass/ SetupDiCreateDeviceInfoList/ SetupDiCreateDeviceInfo sequence. In the end, the call to Updatedriver.. succeeds but I can now see *two* USB devices with same name in the device manager (the name is correct), one is shown working correctly and the other has a yellow companion. Enum\USB has information about 1 device and it is what it should be. ( My removal code thinks there are two devices also I do GetClassDev, EnumDevices and then callClassInstaller with REMOVE, it thinks it has removed two devices.) What am I doing wrong? Let me know if you need any more details. I am new to this and do not know exactly what things are most relevant. cheerio! Tag: Class GUID issue Tag: 38329

    - where can I get Driver Install Frameworks Tools? Hi, Everyone! I read a couple of papers on the Microsoft site about the upcoming new "Driver Install Frameworks Tools" (DIFxApp and DPInst) that were supposed to have come out in December 2003 (Version 1). But all I ended up doing is filling out some survey about participation in Beta 1 program which seemed to have ended already. I want to try out these Tools and see if they help us develop good driver installations, but I cannot even find trial versions of this software. What is the status of these Tools? When and where can I get a hold of trial/beta versions of these? -igor. Tag: Class GUID issue Tag: 38318

    - USB MIDI driver under Windows XP Hi all, We have designed an USB firmware that is a combined Audio+Midi device. We have choosen to use standard USB descriptors to avoid developping drivers under Windows XP. Everything is working fine under Windows XP SP1 except that if we use the midi port with whatever application, if we unplug the USB device (Even if the midi port is closed !) then it stalls the complete plug-and-play system for a good 10 minutes !

    - What must I do to trigger Autorun on my USB storage device? I am looking for some infomation that would help me make my installation program automatically execute from a USB Flash Drive. I found some information in MSDN the following is an extract of that ---------- If you need to make a USB storage device that executes Autorun, the following two conditions must both be true: . Media must be marked as removable. . The device can be set to either static or removable. ----------- The complete information can be found at this location http://www.microsoft.com/whdc/hwdev/bus/USB/usbfaq.mspx The problem is that incase of a USB storage device the media may not be marked as removeable. My question, 1. Is it possible to fool windows by specifying removeable media even for USB drives by burning the media type as removeable on the device itself? 2. Does windows read the media type information from the device or it simply ignores the value of the media for USB drives? Any help would be appreciated. Thanks, Rajesh Tag: Class GUID issue Tag: 38308

    - Filtering Read Hi, I am modifying a upper volume filter driver (similar to diskpref). The operation i am trying is to filter the read. In IRP_MJ_READ i try to block the IRP and then issue my own read IRP to read some data from the disk and then return my read buffer with the original IRP. Now the problem I am facing is the new IRP I am sending down is returning status pending. And after that the system becomes unstable when i try to wait for the IRP completion :( . Can any one help me getting to the bottom of this problem. Is there any i/o mgr restriction that only one read irp can be sent to the underlying device at a time? Please help. Praveen.

    - Unidriver conflict warning problem Dear ALL: I'm developing a driver based on Unidrv. I have a problem as follows: After opening Printer Preferences property sheet, I go to "Paper/Quality" tab, then I go back to "Layout" tab and check duplex(print on both sides). Conflict warning signs for media types such as transparency does not display immediately in the media list box. The warning signs will come out after I select the media type as transparency, click apply and let the system solve the conflict. Also, the conflict warning signs will display correctly if I do not go to "Paper/Quality" tab before checking duplex. I checked .gpd file. It should be correct. I suspect it might be the problem in my ui plug-in dll. Can anyone give me a suggestion? Thanks. Tag: Class GUID issue Tag: 38293

    - UpdateDriverForPlugAndPlayDevice not working in Server 2003 I have an application which launches the installation of my driver using the UpdateDriverForPlugAndPlayDevices function. Under XP Pro SP1 it works as expected. However, under Server 2003 SP1 the device does not install, even when logged in as the administrator. It appears from the setupapi.log that the error is related to my CoInstaller indicating that the default action to should be taken in response to the DIF_REGISTERDEVICE callback request. According to the Server 2003 SP1 DDK, the request is documented as "Can Handle" for Class Installers and CoInstallers, not "Must Handle". So the question is why Server 2003 is finding the default action should be performed response as not acceptable? Tag: Class GUID issue Tag: 38289

    - Loading lower filter on disk devices. I have a lower filter driver that I would like to attach to the DiskDrive device class ({4D36E967-E325-11CE-BFC1- 08002BE10318}). Unfortunately, when I try to load it on this device class, the system will crash during the boot process. The stack trace indicates the fault occurs in nt! IopMarkBootPartition. It does not seem that any code in the driver itself, even DriverEntry, is ever getting called. The same drive will load and function if it is attached to the CDROM device class ({4D36E965-E325-11CE- BFC1-08002BE10318}). Is there some trick to loading lower filters on DiskDrive device that I don't know about? Tag: Class GUID issue Tag: 38286

    - how to prevent OS from picking the old INF over new one Hi, everyone! I am having a problem with automatic driver installation. Namely, I followed the general guidelines from the DDK examples when pre-installing the drivers: I copy the INF with SetupCopyOEMINF to the Inf directory. Everything works fine until the time when I need to install the updated version of the driver. If I copy another INF with a different DriverVer (new date and version), the OS invariably picks the first INF (oem1.inf and not oem2.inf). Setupapi.log records the fact that since the driver is unsigned, the date is ignored. I know that if I manually delete the old INF, the OS will pick my new one (oem2.inf). But I want to avoid scanning through every INF to see which ones can be deleted. Our device is used for highly specialized purposes and works only with our software, so there is not much hope for getting it signed. What can I do to my new INF to make sure that the Configuration Manager picks the newer one every time the automatic device install runs? Are there any other options for me? -igor.

How do I avoid this ? 2) When updating the language monitor, I need to reboot for changes to take effect. Is this how it is supposed to work ? 3) When I use SetPort with an error, the spooler isnt notifyed unless Im printing When I try to print later, the spooler is halted ( as expected ) but I dont get a status telling me what is wrong I use custom errors, ie settings the string member in SetPort PORT_INFO_3 structure Any help ?

    - Microsoft EHCI driver & Multiple URBs Hello, There seems to be a problem of posting concurrent URBs down to the USDB when working with high a speed devices over Microsoft EHCI driver - Sometimes the second pending IRP never completes. In a message from Alexander Grigoriev posted here it can be understood that this is an issue of Microsoft EHCI driver. We are using the latest EHCI driver from Microsoft on an XP SP1 Os (Driver ver: 5.1.2600.1106) with a USB2.0 hub based on Ali chipset. Replacing this driver with the driver from the USB2.0 hub vendor (Ali in our case) solved the issue. Has anyone had a similar problem, has anyone managed to send multiple concurrent URBs to the USBD (with high speed device over Microsoft's EHCI driver) without the driver getting stuck? Any info suggestions or comments regarding this issue will be highly appreciated. Regards, Yariv Ze'evi. Tag: Class GUID issue Tag: 38262

    - FSD Filter Hi, I am modifying FileSpy from IFSKit to enable me to hide files/folders. Everything is working fine except one problem. When my completion routine is called with just one file entry (SL_RETURN_SINGLE_ENTRY set) which I want to hide, I issue another request to get the next file entry. If another file entry exists, the file I want to hide get's hidden properly. If no next entry exists, I return NO_MORE_FILES from the completion routine. The problem is that the user mode seems to ignore this error status altogether. I can still see the file entry for which I returned NO_MORE_FILES (in IO_STATUS_BLOCK). I am properly setting the Information field of iostatus block to zero. If I zero out the buffer for this request, I can still see a folder/file named '0' ! with all it's information (time/attributes etc.). Any clues on what I am missing?

    - 2 Kewaitforsingleobject which waits for same event. Hi, everyone. I posted a message a week ago about ExFreeToNPagedLookasideList. But I found that another matter and maybe above function does not have any problem. KeWaitForSingleObject was used as follows ------ int function A { KeWaitForSingleObject(&Event, Executive, KernelMode, FALSE, NULL); ... KeSetEvent(&Event, 0, FALSE); return int; } static VOID NTAPI function B { KeWaitForSingleObject(&Event, Executive, KernelMode, FALSE, NULL); ... KeSetEvent(&Event, 0, FALSE); +++++++ Call Function A(); } In this case, I thought that Function A will be called after executing function B. But when I debug, event (+++++++) was got in function B in sometimes... my thought : [B -> A] -> A or B debug result : [B -> B] -> A -> A or B (sometimes) Is there any method to solve this problem?

    - Usb isoc transfers and meaning of StartFrame Hello, What I see is the following. The first line is my data stream which consists of packets of 3 frames (ABC is one complete data packet). The second and third lines are from the Urb in the completion routine. Data A x x B C A | B ... IsoPacket.Length 17 0 0 17 17 17 | 17 ... StartFrame 100 | 106 ... The part that's confusing me is that the Data portion looks as though frames 101 and 102 did not occur at all. But the StartFrame member in the next Urb says that they were in fact 6 frames. I would assume that either the Data portion should be A x x A B C | A, or that StartFrame would be 104. Has anyone seen this before, or would hazard a guess as to what is going on? The platform is WinXP, and the device is a USB1.1 device. Thanks in advance, Todd Tag: Class GUID issue Tag: 38247

The XP and later HCT test require you to use a standard class rather
than a private class. Try System.
