    - winusb.sys Hi, My name is Eder, I'm working on a driver with the winusb.dll, but I got lost because I didn't find the winusb.sys on my OS. I'm using winXP and I've already Installed de WDK 6000 wich didn't install the winusb.sys. I got the others dll's (WinUSBCoInstaller.dll,WdfCoInstaller01005.dll) wihch are requested for the .inf but they don't carry any information of this file so, How can I get that file?and Can I get the latest version of WDK in this web site and if I cannot Where can I get it? it's really driving me crazy already. Thanks Tag: NDIS miniport Driver - packet re-ordering Tag: 104022

    - Intersecthandler for my audio loops for 13 times in vista when tried I have the following issue. My AVStream driver has 2 output pins. One is audio and the other is video) I tried to connect the audio pin of my AVStream based driver to the uMedia audio decoder in Vista, it failed to connect. The Intersecthandler for the audio is repeatedly called 13 times inspite of successfully giving the data structure(KSDATARANGE_AUDIO) for the Audio format and gives an error message as "No video port hardware is available, or the hardware is not responding. 0x80040274". However it succesfully connects in the windows XP pc. Video connects in both the operating system successfully(Windows XP & Vista). Is there any change in Vista that Iam overlooking here. I have spent 2-3 days without any luck.

    - getting the device path / device handle of a specific device Hi, I'm trying to write an application which returns me a handle to a device in C#. I already got most of the information needed for this purpose, like the DeviceInfoSet (as IntPtr), the SP_DEVINFO_DATA struct, the device name, ... But the final step, calling SetupDiEnumDeviceInterfaces() to retrieve the SP_DEVICE_INTERFACE_DATA struct fails. Extraction from my code: //get device info set for the device class _deviceInfoSet = SetupDiGetClassDevs(ref _guids[0], 0, IntPtr.Zero, DIGCF_PRESENT); if (_deviceInfoSet.ToInt32() == -1) if (!res) { //device information is unavailable: _deviceName = new StringBuilder(""); _errorcode = -3; return; } //_deviceInfoData.cbSize = (uint) Marshal.SizeOf(_deviceInfoData); _deviceInfoData.cbSize = 28; _deviceInfoData.DevInst = 0; _deviceInfoData.ClassGuid = System.Guid.Empty; _deviceInfoData.Reserved = 0; res = SetupDiEnumDeviceInfo(_deviceInfoSet, _deviceIndex, _deviceInfoData); if (!res) { //no such device: SetupDiDestroyDeviceInfoList(_deviceInfoSet); _deviceName = new StringBuilder(""); _errorcode = -1; return; } // code for get the device name by calling SetupDiGetDeviceRegistryProperty() .... /* ok till here */ SP_DEVICE_INTERFACE_DETAIL_DATA diDetail = new SP_DEVICE_INTERFACE_DETAIL_DATA(); //diDetail.cbSize = (uint) Marshal.SizeOf(diDetail); if (IntPtr.Size == 8) diDetail.cbSize = 8; else diDetail.cbSize = 5; uint size1 = 0; // get Buffer Size bool check = SetupDiGetDeviceInterfaceDetail(_deviceInfoSet, ref _deviceInfoData, IntPtr.Zero, 0, out size1, IntPtr.Zero); check = SetupDiGetDeviceInterfaceDetail(_deviceInfoSet, ref _deviceInfoData, ref diDetail, size1, out size1, IntPtr.Zero); SetupDiGetDeviceInterfaceDetail() always returns false, and size1 stays '0'. What am I doing wrong? Or is there an other way in getting the device path? Maybe there is a function returning the device path when passing the DevInst or Reserved field from SP_DEVINFO_DATA? Other ways I tried: retrieving the device ID by calling CM_Get_Device_ID(); but till now I haven't a way how to get the device path by device ID. IoGetDeviceProperty(); but I don't know how to get PDEVICE_OBJECT (marshalled as IntPtr) as I don't know in which .dll IoGetDeviceObjectPointer() can be found (WineHQ tells me something about 'ntoskrnl.dll' which cannot be found on my WinXP system; so I tried 'ntoskrnl.exe' but got an AccessViolationException with the explanation "Attempted to read or write protected memory. This is often an indication that other memory is corrupt.") As you see, I tried a lot of different ways, but couldn't find the proper solution. Can you help me?

    - ddk build hierarchy question Hi, as i understand the "dirs" file for the build utility should contain only subdirectories (with the location of "dirs" file as the root) and not "../SomeDir". assuming that i have a kind of common library (common drivers routines that i created) to be used for several drivers ( to be used = to be compiled and linked with that lib) and the lib's sources are located above my "dirs" file (my drievrs sources) on the file system. since i can't use "../SomeDir" in my "dirs" file, what options do i have in order to be linked with that lib ? must i create a link from a subdirectory to this directory ? must i build each seperatly ? thanks.

    - Installer Driver Selection and Ranking We have a driver for a 1394 IIDC camera. Windows, in the image.inf file, has a default driver (listing only the compatible hardware ids) for this device. Without going through WHQL certification, how do we get Windows to install our camera driver by default in 2000, XP, and Vista? We're most concerned with the signature score part of the ranking. Our identifier score for the camera is a 0, so obviously that is not a problem. Currently we're looking at purchasing an Authenticode certificate, though we'd like to confirm that the Authenticode signature will be enough to lower our signature score so that our driver is chosen as default. The documentation is not clear on whether a WHQL signature combined with a compatible hardware id is a better or worse match than an Authenticode signature combined with matching hardware ids. Also we're looking at modifying our class coinstaller to handle the DIF_SELECTBESTCOMPATDRV and DIF_SELECTDEVICE requests. Does our coinstaller have to be signed in order to handle these requests?

    - Filtering power button I need to filter the power button press. I was able to determine which ACPI device is registering GUID_DEVICE_SYS_BUTTON. I took the kmdf toaster filter driver sample from the WDK and tried to install it. I added an UpperFilters entry in HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\ACPI\PNP0C0C\2&daba3ff&0. When I rebooted, the filter driver loaded about 50 instances, but AddDevice was never called. So I tried installing as a class filter by creating and UpperFilters entry in HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{4D36E97D-E325-11CE-BFC1-08002BE10318}. This is the "System" class. But when I boot I get the following crash: INACCESSIBLE_BOOT_DEVICE (7b). What is the correct why to install a filter driver on an ACPI device that supports GUID_DEVICE_SYS_BUTTON? Thanks, Michael Tag: NDIS miniport Driver - packet re-ordering Tag: 103982

    - Ethernet Driver is not getting loaded after a shutdown Hello all, I have a strange problem. My ndis ethernet driver gets loaded on windows XP only after reboot. More specifically it is not getting loaded after every shutdown. Device manager is showing resource conflict. But i couldnt find any memory or irq conflict from device manager. (Here if we uninstall the driver and try to scan the hardware, it is not getting detected.)And also it works well if we restart it. Without my driver, hardware is always getting detected irrespective of whether it was a restart or a shutdown(Eventhough is is getting detected if we install the driver ,it will ask for restart if it was shut down previously ,otherwise not.). Driver is not having any dependency problem. inf file also doesnt seem to be causing any problem. Windows event log says that "service cannnot be started. it is disabled since it has no enabled device associated with it." . If this is the case, how come this situation changes, when we restart the system. Or is this a hardware problem. Why is it not being enabled after a shutdown. Looking forward for your responses.

    - VFW Driver on Server 2008 There appears to be a new behavior on Server 2008 for a driver registered with an MSVIDEO entry under the Drivers32 section of the registry. Previous OS versions allowed parameters to be passed to the driver open (DRV_OPEN message) after the dll name. S2K8 appears to be using the entire string as the dll name. Is there a syntax that allows for the dll name on the MSVIDEO REG_SZ data to be followed with parameters? Yes, I know VFW is not supported, but aside from the MSVIDEO change, my driver works fine.

    - How to Uninstall PNP and LowerFilter driver. Our application installs a PnP driver which depends on a storage filter driver configured as a lower filter. When we attempt to uninstall the PnP device via Device Manager and choose to delete the binaries, Vista 64 reports that the filter driver is not signed at boot time. Both drivers have valid WHQL cat files and were installed via a single INF from an MSI file.

    - WinUsb Control_Transfer Question Hi, I need to send a setuppacket (without extra data) to my usb device and the device must respond by sending data back (for example a getstatus request). Code example: WINUSB_SETUP_PACKET SetupPacket; SetupPacket.RequestType = 0xA1; SetupPacket.Request = 0x01; SetupPacket.Value = 0; SetupPacket.Index = 0; SetupPacket.Length = 8; bResult = WinUsb_ControlTransfer( WinUSB_Handle, SetupPacket, DataBuffer, 0, &bytesTransferred, NULL ); When i look at the raw usb data with a USB protocol analyser the .Length member of the setuppacket is send as 0. It seems that the BufferLength value of WinUsb_ControlTransfer overwrites this value. Why? Now the device doesnt know that is must return data. When the BufferLength value of WinUsb_ControlTransfer is set to the value of Setuppacket.Length it is possible to receive data from the device but it the WinUsb_ControlTransfer function also sends useless data to the device. So i would like to know how to read data from the control pipe. Is it possible to use the WinUsb_Read_Pipe function to read from a control pipe? when i try it returns false and the error code is 87 (invalid value). Thanks, Erwin School.

    - Writing to disk under Vista and IOCTL_SCSI_PASS_THROUGH Hello, As per the documentation (and also personal tests) Vista doesn't allow to write to certain parts of a disk even though the program runs with admin privileges. Then after searching the newsgroups I found a message where "Gary G. Little" said it was possible using IOCTL_SCSI_PASS_THROUGH and IOCTL_ATA_PASS_THROUGH. If I understood correctly it should also be possible from a normal user app (i.e. not a driver). http://tinyurl.com/yusjva or http://groups.google.com/group/microsoft.public.development.device.drivers/browse_thread/thread/8dd00a4fa2af1ca3/36c51c0ff38e3c5f?lnk=st&q=write+disk+vista#36c51c0ff38e3c5f The part of his post I used as a guideline is: > You need to look at IOCTL_SCSI_PASS_THROUGH and > IOCTL_ATA_PASS_THROUGH, and understand what an LBA is, and how it is > used in a TFR (which you have to know) and CDB (something else you > have to know). Before it is over you should be intimate with the > SetupDiXxxx API. Though after setting up a minimal example that tries to follow those I could only get it to work when writing to sector 0 and some other sectors but not for all sectors. Below is my sample code that tries to write to sector 6213784 on a 40GB drive (first 20 GB are used by a primary partition formatted with NTFS, and the last 20 GB are unallocated). Some values like sector size are hard coded, I just tried to make it a simple as possible. (Please note that my original code was in Pascal and I made a quick translation to C, just in case you wonder about syntax oddities). h := CreateFile ("\\\\.\\PhysicalDrive0", GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, 0); if (h == INVALID_HANDLE_VALUE) // do error handling ... return; LBA = 6213784; // sector number in linear block addressing BlockCount = 1; // amount of sectors to write ZeroMemory(&sptwb, sizeof(sptwb)); sptwb.sptwb_spt.spt_Length = sizeof(SCSIPASSTHROUGH); sptwb.sptwb_spt.spt_PathId = 0; sptwb.sptwb_spt.spt_TargetId = 1; sptwb.sptwb_spt.spt_Lun = 0; sptwb.sptwb_spt.spt_CdbLength = CDB10GENERIC_LENGTH; // 10 sptwb.sptwb_spt.spt_SenseInfoLength = sizeof(sptwb.sptwb_bSenseBuf); sptwb.sptwb_spt.spt_DataIn = SCSI_IOCTL_DATA_OUT; // 0 sptwb.sptwb_spt.spt_DataTransferLength = sizeof(sptwb.sptwb_bDataBuf); // 512 bytes sptwb.sptwb_spt.spt_TimeOutValue = 5000; // TIME_OUT sptwb.sptwb_spt.spt_DataBufferOffset = &sptwb.sptwb_bDataBuf - &sptwb; sptwb.sptwb_spt.spt_SenseInfoOffset = &sptwb.sptwb_bSenseBuf - &sptwb; sptwb.sptwb_bDataBuf[0] = 'S'; sptwb.sptwb_bDataBuf[1] = 'u'; sptwb.sptwb_bDataBuf[2] = 'c'; sptwb.sptwb_bDataBuf[3] = 'c'; sptwb.sptwb_bDataBuf[4] = 'e'; sptwb.sptwb_bDataBuf[5] = 's'; sptwb.sptwb_bDataBuf[6] = 's'; sptwb.sptwb_spt.spt_Cdb[0] = SCSIOP_WRITE; // 0x2A sptwb.sptwb_spt.spt_Cdb[1] = 0x00; sptwb.sptwb_spt.spt_Cdb[2] = (LBA >> 24) & 0xFF; sptwb.sptwb_spt.spt_Cdb[3] = (LBA >> 16) & 0xFF; sptwb.sptwb_spt.spt_Cdb[4] = (LBA >> 8) & 0xFF; sptwb.sptwb_spt.spt_Cdb[5] = (LBA >> 0) & 0xFF; sptwb.sptwb_spt.spt_Cdb[6] = 0x00; sptwb.sptwb_spt.spt_Cdb[7] = (BlockCount >> 8) & 0xFF; sptwb.sptwb_spt.spt_Cdb[8] = (BlockCount >> 0) & 0xFF; sptwb.sptwb_spt.spt_Cdb[9] = 0x00; if (!DeviceIoControl(h, IOCTL_SCSI_PASS_THROUGH , &sptwb, sizeof(sptwb), &sptwb, sizeof(sptwb), dwBytesReturned, NULL)) // Code to output last error message (GetLastError, etc.) Could you please tell me what of the tips quoted above could make it work? Should I acquire the handle differently, i.e. not use "\\\\.\\PhysicalDrive0" but something else? What is a TFR? Any advice would be greatly appreciated. Regards, Maël Hörz.

    - Forcing scan codes to specific character codes I have a device with a specialized keyboard. I would like to write a filter driver that intercepts the scan codes from some of the keys and force them to specific character codes. The reason for this is because I don't want localized keyboard layouts, num lock, etc to have any affect on these specialized keys. Is this possible to do in a keyboard filter driver? If not, how can this be done? Thanks, Michael Tag: NDIS miniport Driver - packet re-ordering Tag: 103901

    - Replacing DPF with WPP - what's the trick? The toaster sample has a very nice demo that shows how one can switch from WPP based tracing to KdPrint base tracing, just by defining/ udefining EVENT_TRACING. The "trick" is done in the 'sources' file by defining: RUN_WPP=$(SOURCES)\ -km\ -func:ToasterDebugPrint(LEVEL,MSG,...) So that specially made function, ToasterDebugPrint exists even when WPP is enabled and serves *both* KdPrint and WPP. But so far I based my driver's tracing on the DPF, which is a *macro*, not a func (it is basically defining _DbgPrintF). I could have mimicked the toaster sample by defining my own driver's ToasterDebugPrint() function, replacing each and every DPF with it, but it seems too tedious and somewhat dumb. Surely there is a shortcut to reuse my DPF macro, right? How do I let WPP know about the syntax and format of the macro DPF? A tip regarding how to go about this would be highly appreciated.

    - Problem with USB High Speed Hub Hi All, I have developed a USB-Serial KMDF driver for Vista 32-bit. Everything is working fine, but when i connect the USB-Serial device to USB High Speed Hubs which is two level above (two High Speed Hubs), there is a problem. The problem is : I connect USB flash device and USB-Serial device to the external high speed hub. Then i connect a loop back to serial end of device, and open a terminal application like hperterminal and type in any character. the character is read back correctly. When i unplug the USB flash device, the call back routine which i register for reads get returned back with status 0xC0000001 (STATUS_UNSUCCESSFUL). Most importantly this scenario works fine without any problems for Windows XP. The same scenario works fine when i use Full Speed Hubs. The USB- Serial device is full speed device. My question is do i need to consider anything special for USB High Speed hub in my driver or Is this a bug in Windows Vista? All your suggestions are appreciable. Thank You.

    - NdisAcquireReadWriteLock vs NdisAcquireSpinLock I recall seeing some time back that NdisAcquireReadWriteLock was an optimal subsitute for NdisAcquireSpinlock. Is this still true? I can see that the use of a read/write lock could be more optimal than a spinlock when multiple threads are acessing gloabl resources on a read-only basis. However, is this also true when multiple threads try to access a global resource on a write-only basis? In this case, it would seem that the processing overhead of using a read/write lock is >= using a spinlock. Thanks! Tag: NDIS miniport Driver - packet re-ordering Tag: 103871

    - PCI WiFi causes USB Isoch packet loss!? Hi! I have a good working isoch streaming driver (full speed USB, queuing up irp/urb pairs, etc...). I usually run 12-15hrs long tests to see if any packet loss occurs. (XP sp2) If my PCI wireless card is disabled in device manager, or at least the WiFi connection is disabled in network settings, the test completes without any package loss. If the wireless card and the wireless network connection are both enabled (so the connection is alive), isoch packet loss occurs every two minues (exactly 120 seconds). Sometimes every minute (exactly 60 seconds). The packet's fail status is usually 0xC0000A00 (bad startframe) or 0xC000000F. It means that the wireless connection (even if I don't use it at all) interrups my USB stream every 60 or 120 secs (exactly). When I replace the wireless card (US Robotics) with another one (Linksys), the packet loss occurs every 10 minutes. (exactly 600 seconds) Can anyone explain what is going on and how to avoid this? Can I recommend any wireless or registry setting to my driver's users to avoid wifi interruption without disabling their wifi connection?

    - MS Storport KB932755 problem? We have a storport miniport driver sitting on top of our own bus driver. Recently after we update OS with KB932755, we're not able to reboot. System hangs. I've notice the problem comes from the device power IRP of the stack never being able to reach our bus driver to complete it. Storport seems to try to pass the IRP to our bus driver by calling PoCallDriver(). However the IRQL is at DISPATCH when this function being called by storport and the IRP is lost. According to DDK document PoCallDriver() should be at IRQL=PASSIVE_LEVEL because our bus driver reports power IRP must in PASSIVE level by setting DO_POWER_PAGABLE. Did I miss anything here? Can someone from MS have a comment?

    - How are hotkeys handled by filter drivers? I have a HID device that has several non-standard keys. I want to be able to treat these similar to the hotkeys on a keyboard (like the internet, email, search buttons, etc). How are hotkeys typically handled? Are they processed just like an ordinary scan code? Or do you have to do something special like you do with the power related buttons that require registering device interfaces? How does the OS know what to do when it does receive a hotkey? Is this determined by the driver, or is there some user mode component that links up the hotkey with the desired action?

    - 3 issues: PREfast annotations in WDK 6001 I use WDK 6001 to build a user-mode app (this app was always built by DDK since its very beginning 3 years ago). Looks like PREfast annotations just plain do not work for such a build (TARGETTYPE=library or TARGETTYPE=console). Issue 1. For instance, the documentation tells me to use __user_code; in this case. __user_code is defined in driverspecs.h, which CANNOT be included to the user-mode code for WDK builds, since this header file is in (WDK includes)\ddk directory, and this directory is NOT in the include search path for the user-mode WDK builds. Issue 2. More so. The __declspec("SAL_xxx") construct - like __declspec("SAL_deref") - does not work! It causes the "syntax error: string" compiler error. Looks like the compiler lacks some command-line switch or some special definition in the source to be capable of understanding the quoted string inside __declspec. I have tried to create a trivial stupid C file and then build it using my favourite "cl -MD -Ox file.c" command in the WDK's build env window without the BUILD tool at all. Same result: __declspec("...") just cause _syntax_ error, which do not care about what string is in the quotes. What must I add to my SOURCES file for SAL annotations to work? once more - this is user-mode code built by WDK. Issue 3. I have something like: typedef struct _S { PUCHAR SomeData; } S, *PS; f(OUT S* sRet) { PS s; s = (PS)MyAlloc(sizeof(S)); if( s == NULL ) fail; s->SomeData = (PUCHAR)MyAlloc(SomeSize); *sRet = s; return OK; } and PREfast is showing me a warning 6014 about "s->SomeData" being leaked. MyAlloc in this build is resolved to malloc. How annotations can help to remove this warning? The code is valid and has no memory leaks for years, being tested several times on a MFC-style debug allocator (thus MyAlloc). -- Maxim Shatskih, Windows DDK MVP StorageCraft Corporation maxim@storagecraft.com http://www.storagecraft.com Tag: NDIS miniport Driver - packet re-ordering Tag: 103837

    - IOCTL_ATA_PASS_THROUGH vs IOCTL_IDE_PASS_THROUGH (again) I'm developing an Compactflash (CF) manipulation utility to run under Windows/XP Pro SP2. I've run into a perplexing problem: On my Intel ICH9R (set to AHCI mode) driver (Intel Matrix Storage driver), IOCTL_ATA_PASS_THROUGH successfully executes a DEVICE IDENTIFY (0xEC) IOCTL_IDE_PASS_THROUGH fails. On my Jmicron JMB363 PATA (shows up as "Standard dual channel PCI IDE" in device manager), it's the opposite: IOCTL_ATA_PASS_THROUGH fails, but IOCTL_IDE_PASS_THROUGH succeeds. Finally, on the Jmicron SATA/RAID port (this shows up under the 'SCSI/RAID category'), both IOCTL_IDE_PASS_THROUGH and IOCTL_ATA_PASS_THROUGH fail . However, I found sample-code on the web for IOCTL_SCSI_PASS_THROUGH -- that works (for DEVICE IDENTIFY.) Unfortunately, I don't think the SCSI path supports non-standard ATA-commands (Read Long?) Um... is this the situation with Windows XP SP2 storage drivers? Some vendors support some IOCTLs, and others just don't? Basically, am I going to have to code multiple access-methods into my Windows Compactflash utility, and do some convoluted decision-tree logic at runtime?

    - Combining IoCsqRemoveNextIrp with own Cancellation Routine? I am using a CSQ in my driver. So far it works beautifully. However, due to some constraint, even after I remove an IRP using IoCsqRemoveNextIrp(), the time it takes to issue IoCompleteRequest() can vary greatly. Thus, it is possible that -- if the application (that's using this driver) exits exactly at the moment between IoCsqRemoveNextIrp() and IoCompleteRequest() -- the "just removed" IRP will need to be cancelled (instead of completed as intended). This basically calls for setting a cancel routine for the "just removed" IRP, right? Yes, the CSQ has its cancel routine set in IoCsqInitialize() - but that was for the *pending* IRPs (i.e. the ones in the CSQ). Now that a single IRP has been removed fom the CSQ and it is unknown whether it will be completed or cancelled, it needs its own IoSetCancelRoutine(), right? Or did I get this wrong? Regarding terminology, I know that both completed and cancelled use IoCompleteRequest() and the only difference is the returned status (STATUS_SUCCESS etc vs. STATUS_CANCELLED) but for simplicity I call the one "completed" and the other "cancelled". Or do I have another misconception here? Thanks for any clarification of this (delicate) issue. Don Tag: NDIS miniport Driver - packet re-ordering Tag: 103796

Hello,

I'm developing ndis-usb miniport driver.
If IP packet order was corrupted by any reason, Have to I re-order IP
packet?

I've reviewed the TCP / IP Layer concepts in wikipedia.org.
The doc said that TCP layer re-ordered Packets.

NDIS miniport driver isn't TCP / IP layer, so don't have to re-order
packet. right?

Best regards.

The IP protocol driver is responsible for reordering the packets. A miniport
driver is just responsible for delivering packets to the upper layers as
they are received, discarding packets with L2/physical errors (e.g. wrong
FCS).

Hope it helps

I agree with GV that you don't need to reorder the packet.
But the question is why your packets not ordering? Is sender issue or
receiver issue?
You might fail on WDK NDIS testing if your packets are not ordering.
