    - Retrieve MDL from request Hi All, I want to retrieve MDL address from the request which shall be used in DMA transactions. I want to get the MDL address in internal IOCTLs. Intially i used WdfRequestRetrieveOutputWdmMdl/ WdfRequestRetrieveInputputWdmMdl but it always failed with STATUS_BUFFER_TOO_SMALL. So i used the request parameters to get the pointer. But i am not sure how to retrieve the MDL address from request pointers. Can any one help me understand how it can be achieved? Is there any WDF API to retrieve the mdl address from request pointers? WdfRequestGetParameters(Request, &params); params.Parameters.Others.Arg1; Thanks. Regards, Sunishka Tag: USB keyboard Tag: 107794

    - How to evaluate ACPI methods under the child devices in XP? [My problem is under WinXP!] I'm now implementing Video card driver, and got the following difficulty. Following is an example of the ACPI namespace in our system. SB |- PCI |- WMI0 |- VGA |- _DOS |- _DOD |- _ROM |- _DSM |- CRT |- _ADR |- _DCS |- _DGS |- _DSS |- HDMI |- _ADR |- _DCS |- _DGS |- _DSS |- LCD |- _ADR |- _DCS |- _DGS |- _DSS Currently, I can get the PDO (Physical Device Object) of our driver (which means the VGA device in this example) from the DriverEntry. So I can evaluate any ACPI method which belongs to the VGA device (_DOS, _DOD, etc.) by using this PDO. If I want to evaluate the ACPI method under the child device(_DCS, _DGS, etc.), as I know, WMI-tunneling is a way to achieve it. But that need SBIOS to implement somethinig in it so I don't want to evaluate those ACPI methods by WMI tunneling. I found the IOCTL controls IOCTL_ACPI_ENUM_CHILDREN and IOCTL_ACPI_EVAL_METHOD_EX which can enumerate and evaluate the ACPI methods for all devices include childe devices. But unfortunately, these two IOCTL controls are only supported in WinVista. Is there any method to evaluate the ACPI methods which are within child devices in XP? Thanks!

    - WLK not-error message!! I am getting ready for driver signing. I compiled and tested my drivers in WDK 6000. I was trying to install WLK 1.2.6475.0 to do necessary tests. It first complained I have to uninstall WDK 6000 because it is "legacy component". I dont understand this but uninstalled WDK 6000 anyway. Then I ran WLK hoping it may install newer version of WDK. It didnot. Then I thought may be I have to install newer version of WDK 6001 myself later. Let me atleast install the "driver test manager" for now. But then it says "No configuration scenario meets install criteria". I have no clue what this message mean. Should I now install newer WDK 6001 or something and then run this WLK later? Thanks, Raj Tag: USB keyboard Tag: 107784

    - SCSI Miniport in Hibernate Mode Hi all, We've got a SCSIPort Miniport style driver that is hanging the system when it goes into Hibernate mode. We've tracked down where its hanging to a prefetchw assembly instruction. This gets inserted during optimization, and as such, this driver only fails when using the free build. The checked build works fine. My question is whether there's a way to turn off certain aspects of compiler optimization. Specifically, the generation of that prefetchw. If we change the code around a little, we can either get the code to jump over the prefetch, or make sure the compiler doesn't create it. But those solutions add a bunch of memory accesses, which is not ideal since this is in a critical section of code. We suspect that the problem is that prefetchw is not supported on an Intel processor, which is what we are running the driver on. We have not yet had a chance to test this out on an AMD processor. We are using the Microsoft C/C++ Optimizing Compiler Version 14.00.50727.278 for x64. We've tried different flags for changing the optimization levels, but it either creates code that doesn't work, or doesn't optimize at all. We've also tried the /favor:EM64T flag, but that doesn't seem to have an effect. I've noticed other compilers have ways of turning off prefetching specifically, but I couldn't find anything that does that in the Microsoft C compiler. So, I guess my question is, does anyone have either a solution or workaround to our problem, as well as any ideas why a prefetchw instruction would lock up the computer during hibernate mode? Thanks in advance, ~Tom Tag: USB keyboard Tag: 107778

    - TraceView related question: "Invalid parameter passed to C runtime I am new to driver development - I'm working on my first driver project now - and so until the past few weeks I had never used the common tools such as WinDbg and TraceView. I've noticed when I am connected to the target machine (both machines are running XP SP2) with WinDbg, that if TraceView is running on the target machine, "Invalid parameter passed to C runtime function" messages are displayed in WinDbg. These messages seem to be displayed whenever a trace message is posted from my driver. Interestingly, they also seem to be displayed whenever I simply pass the mouse over the TraceView app on the target machine. If TraceView is not running on the target machine, the "invalid parameter..." messages are not displayed. Is this normal? If not, does anybody have any idea what the problem could be?

    - Internal Queues and Start IO Hi All, I am porting WDM SCSI port driver to KMDF. The WDM driver has startio routine and maintains IRPs with internal queues. For WDF version i am planning to create a default queue and forward it to the read/write queue when required. Default queue and read/write queue are both sequential queues. I am not sure if this queuing would work out for me. I have gone through KMDF serial sample for IRP queuing. I think i need to go in similiar lines for managing queues for IRPs and startio routine. I am really stuck up in taking the right decision. Can any one let me know if this queuing mechanism would help me to solve the problem. Any help is much appreciated. Thank You.

    - usb2 serial driver hi.. plz read this.. Serial performs the following tasks to create a COM port device interface: Creates a symbolic link between \DosDevices\<PortName> and the internal device object name for a COM port. <PortName> is the value of the PortName (or Identifier) entry value for the COM port. The Ports class installer sets PortName to COM<n>, where <n> is a COM port number that the installer obtains from the COM port database. Serial uses this name to create a symbolic link to the port. There is no limit to the number of COM ports that Windows supports. User-mode clients use the symbolic link name to open a COM port. here it is mentione that port class installer sets portname to "com" and serial uses it it asa symbolic link....from where port class installer will take this "com".. is there any relation with h/w?why i am asking becz i am developing usb2ser driver ..i htought if i install my driver in port class it will take care of this..is it right?

    - How to force discarding of invalid cached partition contents? A USB hard drive contains a FAT32 partition. Sometimes the partition has a drive letter assigned. When the partition has a drive letter, Windows Explorer and/or some other parts of Windows XP read and cache a portion of the contents. I write part of the partition myself, so I want to force Windows to abandon its cached contents. I call DeviceIoControl several times. FSCTL_LOCK_VOLUME, FSCTL_DISMOUNT_VOLUME, IOCTL_VOLUME_OFFLINE, IOCTL_VOLUME_ONLINE, and FSCTL_UNLOCK_VOLUME. All of these succeed. WinIoCtl.h doesn't define IOCTL_VOLUME_OFFLINE and IOCTL_VOLUME_ONLINE, but MSDN implies that these are supposed to be available to user mode applications, so I define them myself and DeviceIoControl reports success. After that, I have found two ways to do manual operations to force Windows to abandon its cached contents. One is to use Computer Administrator - Disk Administrator, remove the drive letter from the partition, and reassign the drive letter to the partition. The other way is to open a command prompt and run CHKDSK /F, which finds no errors but which somehow persuades Windows XP to discard its cache. If I omit the /F then the obsolete contents remain in the cache, after which Windows proceeds to corrupt the partition and then the next CHKDSK /F adjusts errors (but lost data remain lost). Now I want to do this programmatically. I wonder why obsolete contents remain in the cache after IOCTL_VOLUME_OFFLINE and IOCTL_VOLUME_ONLINE, but continue trying anyway. I added calls to BroadcastSystemMessage with DBT_DEVICEREMOVECOMPLETE and DBT_DEVICEARRIVAL. These report success. Furthermore if Windows Explorer was displaying the partition before these operations, I can see Windows Explorer respond by removing that partition from its display, displaying the contents of another partition, and then restoring the drive letter and icon in the left hand pane though the right hand pane continues displaying the other partition that it had switched to. So I think that DBT_DEVICEREMOVECOMPLETE and DBT_DEVICEARRIVAL have some amount of effect. But when I click on that drive letter in Windows Explorer, it still displays obsolete cached information, and creating a new file causes corruption in the partition. What does it take to force Windows to discard obsolete cached data? Tag: USB keyboard Tag: 107756

    - Reference Counting StartService/ControlService On Legacy Driver Hi All, I have what I imagine is a common problem: I have a legacy NDIS driver that is started/stopped dynamicaly by StartService/ControlService. The problem is that user-mode EXE's, in multiple user accounts, need to start, and perhaps stop, the service, multiple times, simultaneously, during their normal courses of execution. Unfortunately, it seems that the policy of: ControlService (hDriverService, SERVICE_CONTROL_STOP, &status); ...is to force a true stop of the service, always, irrespective of how many StartService calls were invoked to start the driver. I could do what I am doing now, which is simply let the driver stay loaded until reboot, but I was wondering what is the proper way to handle this situation. TIA, -Le Chaud Lapin- Tag: USB keyboard Tag: 107753

    - Monolithic Storage Driver - Partition Creation Failure Using diskpart or the DM UI, initializing our drive fails to create a basic disk (MBR style) intermittently. This failure is timing sensitive and can change across reboots or even insertion of benign dbg traceouts. We have a monolithic storage driver for our device. We see the failure across all versions of Windows. The following show's a failure case using the diskpart CLU. DISKPART> select disk 1 Disk 1 is now the selected disk. DISKPART> clean DiskPart succeeded in cleaning the disk. DISKPART> create partition primary The disk management services could not complete the operation. ******* When using the DM UI, we get the following popup error message when trying to init the disk - "The operation did not complete. Check the System Event Log for more..." in the event log there is a entry saying the following: "VDS fails to write boot code on a disk during clean operation. Error code: 57@02070006." We have turned on debug msgs in the VDS driver and found the following trace out when the partition creation fails: LEAVE CBasicPack::FindDiskByNotificationHandle() INFO: VDS(0X02040002): WM_DEVICECHANGE: wParam=32774 lParam=12385696 ---->>>> ERROR: CVdsPack::ReadFile or WriteFile failed: 57 ENTER CVdsCriticalSection::~CVdsCriticalSection() TRACE: TMP: GUID_IO_VOLUME_MOUNT event received. ENTER LogEvent() LEAVE CVdsCriticalSection::~CVdsCriticalSection() INFO: WM_DEVICECHANGE: wParam=32774 lParam=14482848 ERROR: Event logged: C200000B LEAVE CBasicProvider::OnDiskLayoutChange() INFO: TMP: GUID_IO_VOLUME_MOUNT event received. The 57 error code logged to the event log is the same error code returned by the read/write failure shown above. We have verified that we are not returning failure in any read/write request and that we are not corrupting disk data. In fact, after a reboot, the disk seems to have been successfully initialized, with the MBR data appearing to be correct. It appears to be some timing interaction with two different threads when the partition is being created. They are both from partmgr. We have traced it to the following decision point in partmgr: RtlDeleteElementGenericTableAvl RtlLookupElementGenericTableFullAVL signature = CheckSignature() if (signature == successful) ---> calls PmWritePartitionTableEx gets called and partition is created if (signature != successful) ---> partition is NOT created We have a very detailed Visio flow control document that shows the details of a success versus a failure case that I would be happy to forward to anyone interested in helping out. Thanks for any help and/or ideas. Drex Tag: USB keyboard Tag: 107745

    - DrvTextOut Accessing Font information I'm aware that in the DrvTextOut callback, I can somewhat retrieve information about the font and its glyphs from pfo member of the parameters, which are configured in the DrvQueryFont callback. However, I have not exported this callback in my DDI hooks array, yet I'm getting some numbers for the pfo members when I investigated this pointer in the debugger. As a result, I'm not sure what to make out of this. What is the difference between GDI and driver realized fonts?

    - Standard user can not do driver uninstallation in control panel in Vista I get a problem with the DIFxAPP.msm when building an installer. The merge module comes from DIFx 2.1. We use DIFxAPP.msm to install driver in our installer. After we build the installer (Setup.exe, SPI.msi, Data1.cab) with the merge module, we login Vista 32 with an administrator account, and finish the installation with setup.exe, the driver can be installed correctly. Then we log out, and re-login as a standard user, and do uninstallation in control panel. In the uninstallation process, there will be an error and the process rolls back. Later under the standard user account we use SPI.msi do uninstallation in command line, and the process is same with that in control panel. According the log we catched from command line, the error come from custom action "UninstallDriverPackages" that comes from the DIFxApp.msm Following is the prompt information from the log.

    - W2K package resubmission We have a USB driver package we had qualified way back in mid 2005. It wasn't logo'd; we just needed a signed device driver. We now have a couple more devices serviced by the driver and wish so add their IDs to the INF file, which of course invalidates that .cat file. Anyone know if we can submit the old package with the new INF file and get an updated .cat file without going through the logo program (which is the only thing I see links to)? Paying the driver signing fee will be fine, I would just really prefer not to have to go through the whole (NEW!) test cycle again for an already qualified driver. Thanks!

    - NDIS MINIPORT MiniPortSend() not called after ASSOC Hi folks, in my own WLAN Miniport Driver, NDIS sometimes does not start transmitting the 1st data packet (usually the 1st key of the WPA/PSK EAPOL 4-way-handshake). I have absolutely no idea, why What I have is: After getting the interrupt from WLAN Chip, which is reporting "okay from 802.11 ASSOC", I send to NDIS: NdisMIndicateStatus ( Adapter->MyAdapterHdl, NDIS_STATUS_MEDIA_DISCONNECT, NULL, 0 ); NdisMIndicateStatusComplete ( Adapter->MyAdapterHdl ); Is this _not_ enought to force NDIS the start of Tx/Rx? The last status was _not_ NDIS_STATUS_RESSOURCES, so NdisMSendComplete() could also not be the reason, right? in fact, I get this problems right after rebooting the device, so the Miniport can not be in NDIS_STATUS_RESSOURCES state, I assume... BTW: the driver is currently build for WinCE5.0, which is NDIS 5.1. The port for WinXP is long time not maintained and the hardware is also no longer avail for desktop. Thus, I cannot check if I have the same problems under any WinNT. Any help is highly appreciated! -- Mai Kee Reiss Tag: USB keyboard Tag: 107716

    - Troubleshooting Sleep Issues - Continued Volodymyr, I let this sit for a biut, so I'm re-posting. I fiddled around with WinDBG on a test machine. I use WinDBG quite frequently to analyze crash reports, but that's about the extent of my knowledge with it. I was able to put Windows into the /debug state, no problem. Rebooted, then opened up WinDBG, here's where I get a little lost. I'm not sure from the instructions whether I'm supposed to be doing a kernel debug, or attaching to a process. It also sounds like they are doing a remote debug, how would I do this? From another machine, connected to the target machine via the Serial port, or firewire/USB? I did a kernel debug locally, however I can't set the breakpoint to GetThreadExecutionState when in kernel mode. Unless I'm doing it wrong. I was however able to attach the debugger to the shell, explorer.exe. This did allow me to set that breakpoint and monitor the call traces. But it almost seemed to lock up at times & was unstable. So I believe I really need to do a remote debug, found Instructions on how-to do that. However it doesn't really seem to apply to my particular situation, as I don't have a specific app. or dll that I'm debugging. Any help on executing this would be great. Thx. a bunch. =) -- Thx.

    - USB - send data using bulk pipe Hi all, I would like to send and receive data using bulk pipes. My data would exceed the max. packet size of my full speed device (64B). On the host side I'm using WinUsb. Is it possible to send data, larger than 64B using one call to WinUsb's WinUsb_WritePipe, or should I split the data to fit into a 64B data packets? What about receiving data from the device, Is it possible to send "a big buffer" (>64B) using one call to WinUsb's API? Thanks, AssafT Tag: USB keyboard Tag: 107706

    - Regarding CPSUI Hi, I have been implementing a printer interface DLL which uses normal Win32 dialog based property pagesinstead of CPSUI based property pages and noticed following issues. 1. The PROPSHEETUI_REASON_SET_RESULT is never called in case of Win32 dialog based property pages. I am not sure whether there is any way to make this get called. 2. If I open from control panel -> printer properties, the settings changes are not saved in the DEVMODE due to problem 1. I have to explictly save the settings using GetPrinter() functions. I believe this also is related to (1) What are the additional things to be done when non-CPSUI based printer property pages are used? Thanks. Tag: USB keyboard Tag: 107701

    - How do i send a captured data to print spooler for printing. Hi, let me explain you what actually am trying to do. writeprinter() function in a rendering plug-in of a Unidrv printer driver if implemented , enables us to capture the out put data generated by the Unidrv printer driver. So am trying to implement this function there by capturing the data the driver is giving out. So , for this i have written a function which opens a file captures the driver data .But to my surprise am not able to get any data ,but NULL is being captured. You can see my implementation as below.. HRESULT __stdcall COemUni2:: WritePrinter( PDEVOBJ pdevobj, PVOID pBuf, DWORD cbBuffer, PDWORD pcbWritten ) { BOOL bResult; bResult = GetDriverOutput(pdevobj, pBuf, cbBuffer, pcbWritten); if(bResult) { return S_OK; } return S_FALSE; } BOOL GetDriverOutput(PDEVOBJ pdevobj, PVOID pBuf, DWORD cbBuffer, PDWORD pcbWritten) { FILE *fp1; char* sFile; sFile = "E:\\result.txt"; HANDLE hFile1 = CreateFile((LPCTSTR)sFile, GENERIC_WRITE | GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE | FILE_SHARE_DELETE, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL); if( (fp1 = fopen( sFile, "w" )) == NULL ){ return FALSE; } fprintf(fp1, "%s", pBuf); fclose(fp1); CloseHandle(hFile1); return TRUE; } This is what i implemented. I dont know why NULL is being captured .... Now my objective is to capture the correct out put data generated by Unidrv driver and also i should send this data what ever captured ,to the print spooler for printing and this should be done automatically by my function . So please throw some light , by giving me some idea on how do i do this and please let me know where exactly am going wrong. Thanks in advance for your time and help. Please let me know if you still want any more details from my side. Thanks, Tag: USB keyboard Tag: 107695

    - Windows driver debugging using 1394 Hello all !!! I am new to windows device driver development... I want to setup the remote debugging using 1394 fireware card. I followed the steps in the document DW04001_WINHEC2004. In the host side I installed the debugging tool (version 6.9.3.113). But as discussed in the document when i started WinDbg wih 1394 enabled in channel 10 it was not installing two drivers ,it was installing only one driver - 1394 windows debug driver (kernel mode) (1394kdbg.sys). It was not installing 1394 windows debug XP driver, and the Windbg application was showing the message "Waiting to reconnect". I followed the same steps in the document in target side and restarted the target machine.. But it was not connecting to the host.. I used the 6-6 pin to connect host and target. Anyone could you please help me... is it necessary to install 1394 windows debug XP driver in host side to make it work ???.. Both Host and Target machine is running Wondows XP SP2. Could you please give your valuable suggestion for to make it work ???? Thanks in advance Biju Tag: USB keyboard Tag: 107691

    - WinUsb_Initialize failing with ERROR_BAD_DEVICE Hi. I've got a driver based on the FX2 sample. When plugging in the hardware, the my driver starts loading and wudfhost is running. I've used the debugger to break into it and see my driver calling IWDFUsbTargetFactory::CreateUsbTargetDevice. That's failing with ERROR_BAD_DEVICE. According to the docs, this would be an error code returned by WinUSB_Initialize. The device name is \\.\UMDFCtrlDev-3e5e32b1-51b0-11dd-813d-0010dc4ece8d from a previous call to IWDFDevice::RetrieveDeviceName. I've even tried taking the FX2 driver source as is and just modifiying the vendor ID and PID to match my hardware, realizing that it would fail later in the process after WinUSB initialized. The result is the same. Any guesses as to what I might have wrong? Thanks, Steve Tag: USB keyboard Tag: 107690

    - How to get enumerator's DO (due to possible system bug)? Hi. Is there any way to get the device object of the bus driver whoâ??s created the PDO to which our device is attached? To be precise, I have a legacy PCI device which works more reliably with old applications if itâ??s been assigned legacy I/O addresses (i.e. 12-bit ISA ports below 0x1000). To achieve this, I use the PCI bridge subtractive-decode: add extra resource lists with desired resources to the resource requirements list and then rely on PnP Manager to assign one if available, or just use boot resources in case of a positive-only bridge or if resources arenâ??t available. However, on one particular system, Iâ??ve hit a problem where although the bridge does not support subtractive-decode (based on â??How Windows Identifies and Supports Bridge Typesâ?? section of â??Supporting Subtractive PCI-to-PCI Bridges in Windowsâ??), PnP manager still sends me resources which are only available for a subtractive-decode bridge. This apparently ends up in a crash and possibly is a bug in PnP/PCI driver(?). As a workaround, Iâ??m trying to get the device object of the underlying PCI bridge (which is on a different stack) and use it to read the PCI config space of the bridge and verify if the programming interface (in class code) is 01. How could this be done? Are there any other ways of achieving this? Thanks, DaveH Tag: USB keyboard Tag: 107683

    - Generating keystrokes over USB Hi, I have a USB device, which you plug between a PC and a USB keyboard. The device normally works by responding to keystrokes from the keyboard, but what I want to do is to generate keystrokes programmatically from the PC. I know that OUT is an "unnatural" direction for keystrokes, but I hope to activate the device that way rather than by user interaction. Note that this is completely different from internal Windows events such as KEY_UP/DOWN/SendInput/etc. Does anyone know how to send a keystroke? Tag: USB keyboard Tag: 107674

    - WDF driver on PIII dual processor Hi, I am working on a PCI driver, have tested the driver in different hardware combinations, it is observed that, test ouputs on WDF driver on PIII dual processor was different from others, here is summary. Test works in Uni processor & Quad core, but it fails in Dual processor PC, here it fails very few tests out of 15000 tests. Test generates around 60000 interrupts along with read & write DMA access, which also generate interrupts accordingly, based on read/write data, tests generates the interrupts. I am currently synchronizing all read, write, IOCTL requests, so in my idea, there wont be any chance that two requests would be running simultaneously on any core Just wanted to know, Any special care to be taken in Dual processor systems compared to muliticore PC's? Dual processor configuration: PIII, 550Hz 386MB RAM. I hope WDF works fine with Old processor configuration also. Thanks, Prafulla Tag: USB keyboard Tag: 107673

    - Power Dispatch for XP driver in both platforms? Dear Sir: I have 1 driver for Serial-to-USB, it is WDM driver for XP driver. I put WDM-XP driver into Vista platform to run, and it will run in most parts of functions. I attached the modem to Serial-Port, use terminal to send "AT" command and it will return "OK".

I'm a bit perplexed though as I have a 32 bit application that calls into the driver, the driver calls EngAllocUserMem (and gets a 64 bit pointer), then passes that value back to my 32 bit app. How can I thunk the address from the 64 bit driver (that created memory in my 32 bit process), back to my 32 bit process so I can access the memory?

    - Print Driver Font Rotation Problem I am currently developing a rendering plug-in for Unidrv. When an application creates a font with the same orientation and escapement, I get an XFORM transformation that properly rotates the text. However, if the application specifies a a orientation and escapement that are different, the XFORM doesn't contain any shear and my printer output does not match the video display's output. In my OEMTextOut routine, I get an SO_ESC_NOT_ORIENT flag to tell me that they're different but I can't find out what the difference actually is. If I could get that delta, I could do a simple matrix operation to take the angle difference into account and get a proper display. Any input would be greatly appreciated!
