    - Device Manager - Disable->Enable = (Code 39) I have a SCSI MiniPort that was working fine on WinXP SP2 although when I updated SP2 with the latest critical patches I started seeing this problem. In the device manager I can see my SCSI Controller and one disk which is hanging off it. If I disable the SCSI controller in device manager the disk goes away as expected. Although if I re-enable the SCSI adapter the disk returns but with a bang and Code 39. (Rebooting the system once in this state resolves the problem. Also rebooting in between the disable and enable works around the issue. Tracing the driver its running fine. No errors.) I ran across a couple kb article which looks like an exact match although it only seems to apply to CD/DVDs. And there workarounds don't match up for a disk device. Has anyone encountered this and do you know of solutions / workarounds? Tag: WDK version number programatically Tag: 101196

    - Bitmap printer driver on XP I try to adapt Bitmap sample (from DDK) to save in JPEG or other formats, all pages printed. I'ts works well when all pages have the same orientation (all pages in portrait, or all pages in landscape). But when I try to print mixed pages from Word or other software, I get only the last one. Example : 1st page is in Portrait 2nd page is in Landscape 3th page is in Portrait I get only the page #3. In debug mode, i see the OEMSendpage is never called in these case. Have you an idea of my problem ? Thanks Tag: WDK version number programatically Tag: 101191

    - Virtual Multiort serial Adapters Hello All, Thanks for all the inputs you have given me. I am writing a driver for virtual multiport serial adapter(windows XP,2000). I have created a virtual bus driver ( Bus FDO). I can create the multiple virtual ports also (Port PDOs). Later I can add the same number of Port FDO s as my PDO s, to create COM interface to my applications. Now I have a Multiple virtual COM interface. But the exact requirement of my project is to create the ports only when instructed by an application above. I think I can delay the making of FDO (so that there is no COM interface). But since the PDO s are present(which were installed when bus driver was inserted.). It shows in the device manager as unknown device. I dont want this to happen. Is there any way I could dynamically install Port PDO s(not along with Bus driver), when i get signal from application. More specifically "CAN A BUS DRIVER, DYNAMICALLY ENUMERATE ITS PORTS (NOT DEVICES CONNECTED TO ITS PORTS)". or the only way I have is to insert another bus driver when i want another port. Looking forward for you response Thanks in advance, Subhash Tag: WDK version number programatically Tag: 101188

    - About KSPIN format Hi, I am doing a USB Avstream Device Driver, I wanted to stream MPEG2 TS data through USB to be played on PC using directshow. I am using a pin centric approach in the avstream, my question is, how do i let the upper layer graph builder knows about the format of the upcoming data format (eg. MPEG2 TS) .... i could do it in onSetDataFormat() and IntersectHandler() in the Pin class right?? How do i do it? I am quite new to this, any cautions on TS streams also greatly appreciated. Is there any sample in the DDK that show this ? Thanks -- -------------------------------------------- William Tag: WDK version number programatically Tag: 101179

    - ksthunk.sys in 64bit Windows I have developed a class upper filter driver used in "Image" class. It is for processing video frames that is produced by pc cameras. But I find there is a system-provided class upper filter driver named ksthunk.sys already (with Winxp 64bit / WinVista 64bit). If I put my filter driver after ksthunk in registry, it means when device loaded ksthunk will be under my filter driver in driver stack. The problem is every user mode virtual address is invalid! If I put my filter driver in front of it , things are OK. I want to know must I put my filter driver in front of ksthunk in registry? Tag: WDK version number programatically Tag: 101177

    - Issues about USB composite device driver I want to develop an USB composite device driver. The device has one configuration and 6 interfaces in it. According desription of DDK(2003 sp1, 3790.1830) documents, Windows system(XP and later) had supplied an USB common class generic parent driver, that is usbccgp.sys. This driver can be loaded when our device pluged in and create 6 PDO for each interface. So we can install driver for each interface. But I have found some problems about this description. 1. OS can't find the usbccgp.sys driver and install it automatically for our device. I had searched the c: partition(my system disk) but can't find the usbccgp.sys file. My Windows system is XP sp2. Why and where can I get the usbccgp.sys file? 2. I write a inf file and reference usbhub.sys to install driver for our device. Yes! usbhub.sys can work! It enumrates 6 devices from our device for each interface. Then I install drivers for each device. I can install driver for interface number 0(matched ID is USB\VID_xxxx&PID_xxxx&MI_00) and the driver work well. But when I try to install driver for other interface, it failed! The failed position is when I try to select configuration for USB device with USBD_CreateConfigurationRequestEx and submit it to host driver. Laterly, I found some useful information from DDK document. It said that host driver can't support selecting configuration in composite USB device. But the problem is that where can I get the interface information and pipe information(ep address and pipe handle etc.) if I can't get those information from selecting configuration? Please help me, thank you very much! Abei.liu 12/05/2007 Tag: WDK version number programatically Tag: 101153

    - WHQL certification of laptop - USB issue Hello I'm stuck with strange behaviour of the USB subsystem preventing requirements for WHQL certification of a laptop with an embedded USB device. First things first. Here's an interesting test: I'm experiencing a strange phenomenon with USB devices that are surprise-removed during standby. I've seen it happening with USB hubs, USB sticks, USB hard drives and USB 3G devices. It happens in Win2000 and WinXP. These are the steps taken: 1. Plug in one of the mentioned USB devices. 2. In Bootvis, initiate standby test. 3. During standby, unplug the USB device -> surprise-removal. 4. Resume. 5. Wait for Bootvis to finish. In Bootvis you can see that the device driver of the unplugged USB device eats an extra +/- 3 seconds of resume time (compared with the resume time in a situation where you do not unplug the device). The exact device driver depends on the USB device; I've noticed the 3 extra seconds with usbhub.sys, usbcgpp.sys, usbstor.sys, and gt72ubus.sys (3th party 3G driver). When you unplug multiple USB device during standby, the system eats 3 seconds for each unplugged device. I found out that during resume from standby, the USB subsystem eats 3 seconds for each unplugged device during standby. Technically: When a USB function driver sends down the set D0 power request for an unplugged device, some lower-level code happily sleeps for 3 seconds and completes the request. At this point, the USB function driver doesn't know of the surprise-removal yet; that event happens later. Can anyone tell me why Win2000/XP behaves like this? So in my case: The laptop has a built-in embedded USB function, a MiniPCIe card. The laptop de-powers the card during standby, hence a surprise-removal happens and resume from standby takes an extra 3 seconds. As a result, the total resume time for this laptop takes more than 5 seconds. The laptop needs to be WHQL-certified (logo) for WinXP. Because of the long resume time, the laptop doesn't meet the requirements. Pretty annoying. Any suggestions? Tag: WDK version number programatically Tag: 101152

    - STATUS_UNSUCCESSFUL after calling WdfDeviceStopIdle Hi experts, I'm facing a problem with my KMDF USB driver when coming back from idle (D2 power state) My USB driver receives no IRPs (or WDFREQUESTS for that matter). Data passes through it only via direct function calls from an NDIS miniport on a different stack. I've set the idle timeout to be 1 millisecond and the idle setting are by default "off", i.e. I call WdfDeviceStopIdle as soon as the miniport connects to USB driver Whenever I want to go to low power state, the driver calls WdfDeviceResumeIdle and the driver goes to D2. All work fine until this point. Whenever I want to restore my communication with the device I call WdfDeviceStopIdle. In the context of the EvtDeviceSelfManagedIoRestart (after we're in D0) I send the request. The problem is that the requrest fails with status 0xC0000001. The USBD status of the failure is 0x0. Same failure occurs for both read and write request. Same failure occurs even if the request is sent not from the context of the EvtDeviceSelfManagedIoRestart context but rather from the context of a dedicated workitem which is spawned from the EvtDeviceSelfManagedIoRestart context. I used a USB sniffer to sense what is going on when the error occurs; I see that there are no Start of Frames (SOFs) at all! When I increase the idle timeout to about 250 milliseconds the problem disappears. I have no explanation for this. I can supply the KMDF log of the failure if anyone wishes to see. I've looked at it but saw no explanation for the failure. What could be the reasons for this error status? My guess is that the USB host controller hasn't resumed from the selective suspend state although the framework has already sent me an IoRestart event. Please help. Thanks, Yoav.

    - USB 2.0 ISO Allways at Beginning of SOF? Using a high-bandwidth ISO endpoint ( 3- 1024 packets), and only one USB ISO device in system. Question: Since the system allocates a maximum of 80% bandwidth the ISO endpoint, is it guaranteed that the ISO xfer (IN token) will ALWAYS occur at the beginning of the microframe(SOF)? So if there is a control xfer or something else in the same microframe, at SOF the ISO xfer is serviced first, then the remaining 20% at the end of the microframe for the control transfer? I didn't see anything in the USB 2.0 spec. Thanks -decoder Tag: WDK version number programatically Tag: 101139

    - IoCompletion and free the driver-allocated IRP By attaching buffers for isochronous transfer with 1394 kmdf driver: the t1394_IsochAttachBuffers function passes the IRP to next-lower driver with IoSetCompletionRoutine( newIrp, t1394_IsochAttachCompletionRoutine, IsochDetachData, TRUE, TRUE, TRUE ); IoCallDriver(deviceExtension->StackDeviceObject, newIrp); Then the driver calls t1394_IsochAttachCompletionRoutine. The IoCompletionRoutine checks with 'if (!NT_SUCCESS(Irp->IoStatus.Status))', ; ---------------------------------------------------------------------------------------------------------------------------------- Irp->IoStatus.Status is 0x0, I think, it means STATUS_SUCCESS, so !NT_SUCCESS(Irp->IoStatus.Status) == FALSE. ---------------------------------------------------------------------------------------------------------------------------------- jumps to end of this IoCompletionRoutine and returns 'STATUS_MORE_PROCESSING_REQUIRED'. The t1394_IsochAttachBuffers function returns STATUS_PENDING. So the nStatus will be stay by STATUS_PENDING forever and the application freezes by calling GetOverlappedResult(hDevice, &overLapped, &dwBytesRet, TRUE) function. So far I have understood... In the msdn article about 'IoCompletion', I saw these line : If an IoCompletion routine returns STATUS_MORE_PROCESSING_REQUIRED, the lower driver's call to IoCompleteRequest immediately returns. In this case, a higher-level driver will have to call IoCompleteRequest to complete the IRP. I found the WdfRequestCompleteWithInformation function in my source code, but this will be call just for the case !NT_SUCCESS(Irp->IoStatus.Status) == TRUE (I think, this is the case for invalid parameters). So, shouldn't be there also a WdfRequestComplete function for !NT_SUCCESS(Irp->IoStatus.Status) == FALSE ? thanks in advance min Tag: WDK version number programatically Tag: 101137

    - A simple file access monitor hello, I need to write a application that can monitor file/share access and the users who did the operation. I know they are things out there that get close to it like the FileSystemWatcher() funcion in .Net that almost fits my needs except that it doesn't know who did the changes. Also I don't want to user syslog because it is not designed for this and also not really fast. Right now all I could find on the net that could help me along was to implement a minifilter myself. Is it possible to find out the user who performed an operation on a file or a share with a minifilter driver? Best Regard and thank you for any help. V.

    - Occasional performance issue with EngModifySurface We have an application that draw an animation into a layered window as fast as possible. I post here because the problem is related to win32k and EngModifySurface. Please tell me if another group is a better place for this post. On some hardware the animation is always fast. On others hardware, sometimes the animation is slow, sometimes the animation is fast. This occur immediately after the window is created. When the window is closed and reopened (without closing the process ), it can again be slow or fast, but this never switch after the initialisation of the window. I profiled the application in the two cases using Kernrate. The logs tell us that there is more time spend in the function EngModifySurface in win32k when the application is slow and that something is slowing down EngModifySurface around the address 0xbf8be470 and 0xbf8be4c0. Does anyone know what happen at this address, or a way to know it and how this could be fixed so that the animation is always fast ? Here is the simplified log of Kernrate in the slow case first and in the fast case in second. All the measures were done on the same computer. Thank you very much for attention.

    - KMDF: Use of KeSetImportanceDpc()? I'm writing a KMDF driver for a network device with very small paket buffers. I transfer data from the device in DPC. Latency between interrupt and DPC call is critical, because the DPC has to be called within typical 250-500 microseconds after the device raises its interrupt, else pakets are lost. To solve this, I'd like to experiment with "KeSetImportanceDpc()". Questions: - I think I need to use WdfDpcWdmGetDpc(), but how do I access the WDFDPC-handle of a DPC, which was declared indirectly with .... WDF_INTERRUPT_CONFIG_INIT(&interruptConfig, MY_ISR, MY_DPC); status = WdfInterruptCreate(pDeviceContext->Device, &interruptConfig, WDF_NO_OBJECT_ATTRIBUTES, &pDeviceContext->Interrupt); .... ? - Where should I call KeSetImportanceDpc() ? In the ISR directly before WdfInterruptQueueDpcForIsr()? Thanks, J. Hoppe, PEAK System Technik Tag: WDK version number programatically Tag: 101113

    - slow boot windows xp Hello, For a couple of mounts, I'v a slow boot of windows xp on my acer laptop 9412. First, I thought a virus or rootkit but the tools I tried don't find anything of important (S&D, AVG, Bitdefender, SDoctor). Starting in save mode works better but also slow. Bootvis isn't helping me very well. It only shows often 100% disk use during boot which I knew already by the HD led. Watching processes with process explorer from sysinternals, I see a lot of interrupts during boot; around 45% CPU use during boot. Using process monitor, I see a long file time in the file summary for c:\$ConvertToNonresident (around 45% of total file time). I suppose there is an NTFS problem but defragmentation doesn't help. I hope this newsgroup has the knowledge what is the problem or what causes it. What is happening ? How do I solve this slow boot problem ? In the stack summary, I see some <unknown>. I suppose that's normal ? Tag: WDK version number programatically Tag: 101102

    - Driver Problem with Canon LBP2900 Printer Hi Folks, Unfortunately, I encounter a problem with my brand new laser printer Canon LBP2900. It is connected to my computer (Windows Vista) via an USB cable and works properly as long as I am offline. But once I go online, data transfer from the computer to the printer will take several minutes. This phenomenon seems not to depend on the size of the file to be printed. Pages are not printed stepwise (with time interruptions between different pages) but in one single go once printing is initiated. I suspected the firewall (Norton) to be responsible for this delay. But even if I turned it off, delayed printing did persist. I have already uninstalled the printer driver and reinstalled when I was online with no effect on the slowed data transfer to the printer. During data transfer, the program I want to print from (Word, Adobe Acrobat etc.) seems to be pretty busy (task manager will temporarily show 'Not Responding'). When I want to print a PDF, the green status bar will rest at zero percent for ages. Then (after several minutes) it will abruptly turn to 100%. I would be very pleased if somebody could give me some advice here. Thank you so much. Regards Ulf Tag: WDK version number programatically Tag: 101094

    - SpinLock in DPC and IOCTL Hi, I use a spin lock to synch my IOCTLs (which can be called from several user mode clients), and my DPC. How will the system behave in the next scenario: IOCTL xxx has been called, and starts to run in PASSIVE_LEVEL and aquires spin lock MyLock. During its excecution, an interrupt has been triggered by the hardware, and a DPC starts to run in DISPATCH_LEVEL, aquiring MyLock. Will it waits to MyLock to be released (which means that DPC waits for IOCTL to be completed) or will it run ignoring the lock (because its in higher IRQL)? Thanks, Avi.

    - how can I kernel debug NDIS IM driver "passthru" example in VMWare?! After I install the "passthru" in vmware succesfully, then connect to vmware using windbg, and set some breakpoint on "PtReceivePacket" or MP* functions, it simply doesn't stop there. I use bridged mode in vmware for the NIC. I can surf the internet in the vmware machine, does this mean that the packet doesn't go through "passthru"?? Thanks for any reply.

    - Running DTM in VMWare I tried to run the NDISTest for my CoNDIS WAN virtual virtual adapter. Since the current NDISTest is boundaled with DTM, I need to install the DTM controller and studio in a server in oder to run the NDISTest. What I did is as follows. 1. Install DTM controller and studio in a server runnning a VM. 2. Install my CoNDIS Virtul WAN and DTM client in Windows XP running in a another VM. In the above configuration, I can create the machine pool to monitor the job without any problem. But when I tried to create a submission, it always fail in a few steps after running the Wizzard. Does anybody have any experiece to run the DTM on a Vmware? If I cannot run the DTM in the VMware, can I just run the NDISTest in the VMWare? then how?

    - EvtWmiInstanceExecuteMethod OutBufferSize problem Hello, I wrote a driver which supports a WMI ExecuteMethod. I wrote a Vbscript program to test the method but the OutBufferSize in the EvtWmiInstanceExecuteMethod is aways 5 which is not big enough for the return data. The method takes inputs and returns parameters including and array of data. Why is the OutBufferSize always 5 ? Is there away to tell the Swbemobject what size I want the Output buffer to be ? Usually the input buffer is the output buffer from the EvtWmiInstanceExecuteMethod point of view but I don't know how SWBemojbect come up with a OutBuffersSize of 5.

    - Writing a USB device driver for a trackball I have a mouse and a trackball on my pc. I would like the mouse to act as normal mouse that controls the cursor. I would like the trackball to act as a separate device which does not act like a mouse. Right now, when I plug both in, I get two mice. The trackball uses HID-compliant mouse driver in the device manager. I was hoping to write a new driver and install it instead of the HID- compliant driver. I could then use the new driver in my application to simply read delta x and y from the trackball. Could anyone give me some ideas on this? Is there any similar source code that I could modify? I open to other methods too. I examined using Raw input but ran into so roadblocks. Tag: WDK version number programatically Tag: 101075

    - Printer UI Plugin Hi, after reading a lot of documentation about UI and rendering plug in , I would like to know if I well understand. with rendering plug in, I can intercept the data flow sent to te printer through the print job , for example. and with UI plug in, I can add property page to the print document or print device, and store setting data into the registry. Now, I think that I can only communicate with the printer through the rendering plug in, and so , I wonder how to send data directly to my printer from my UI plug in without to execute a print job. I think I don't understand all the process of the printing. If anyone can help me, I really appreciate. and sorry for my poor english. thank you Tag: WDK version number programatically Tag: 101068

    - What does it take to get PCI bus master privileges in Vista? I have a pair of NDIS drivers that sit on top of a bus driver that controls a PCI device. In Vista32 one NDIS driver that sits on top of our bus driver calls NdisMSetMiniportAttributes with the attributes flag set to NDIS_MINIPORT_ATTRIBUTES_BUS_MASTER. I can allocate shared memory. In Vista64, the same driver, the same source code, the same call to NdisMSetMiniportAttributes, with the same attributes flag set to NDIS_MINIPORT_ATTRIBUTES_BUS_MASTER, and I CAN NOT allocate shared memory. What other things does this NDIS driver have to do to join the 64 bit bus master club? Thanks -Ron- Tag: WDK version number programatically Tag: 101043

    - Vitsa driver load reload problem I know I've seen commants on this before but Google is just swamped with stuff relating to 'Vista' and 'driver'. I have a little test utility to exercise a driver I'm working on. As a convienence, it contains buttons to spawn devcon commands to install/update/restart my driver. The update button (via the .inf) causes the latest build of my driver to be copied to system32\drivers and then fires up the new code. All this works great on XP. On Vista, either the copy takes place and it gets overwritten by the previous version or the copy never takes place. The automatic driver restore monster seems to be in the game. Is there any magic that can be applied from the command line (i.e. devcon) to make Vista behave? The driver is in a system defined class and is signed using a test certificate (pending receipt of real certificate) Thanks, Mickey. Tag: WDK version number programatically Tag: 101028

    - how to use pvOut in DOCUMENTEVENT_CREATEDCPRE Hi, The documentation given in MSDN for pvOut variable for function IPrintOemUI2:DocumentEvent with iEsc DOCUMENTEVENT_CREATEDCPRE is as follows: Pointer to a driver-supplied DEVMODE structure, which GDI uses instead of the one supplied by the CreateDC caller. (If NULL, GDI uses the caller-supplied structure.) I am implementing my own ui plug in. In this plug in i am trying to change the values of some of the public devmode member variables. I tried assigning the new values to members variables of pvOut. Even though the change is reflected in iEsc DOCUMENTEVENT_CREATEDCPOST, the change is not reflected in the print job. ie if I change pvOut- >dmDuplex to DMUP_HORIZONTAL from DMUP_SIMPLEX, the print job is still simplex. The above problem is observed in MSWORD and other office applications. It works fine for notepad, adobe reader etc. Can I any one point out the right way to store the devmode settings?
