    - Job opportunities Hi everyone, My employer has opened or is about to open several positions. Four of them require skills and proficiency in Windows driver writing, especially in Network and Storage drivers. Thus there are great chances that the potential candidates are readers of this newsgroup (and a few other ones. I am cross-posting). I know this group is not made for that purpose and I apologize in advance to those of you who are not interested (sorry for the cross postings too, but the skills we are searching are quite hard to find, I want to maximize our chances to find the right future colleagues). Two positions are opened in Paris, France and two will be opened in the USA (east coast) very soon. In each location there is one Senior Engineer position and one Developer-Engineer position. Contact me in private (jobs at windowsdiskless dot com) for more details (this is a forwarded e-mail address and I will receive the e-mails sent to this address). This is a real opportunity, not a fake! Thanks in advance -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/ Tag: Developing a device driver for a WiFi device Tag: 95355

    - optimazation options on free build environment by default Hi all. I have a question about free build environment on WDK(version 6000). On x86 Free Build Environment, MSC_OPTIMIZATION defaults to /0xs. I understand that /Oxs implies the use of the Frame Pointer Omission (/Oy) option. but /Oy- is appointed in compile. This cause is so that it is written as the following in "i386mk.inc" . DBGFLAGS=$(DBGFLAGS) /Oy- CFLAGS=$(386_FLAGS) $(NT386FLAGS) $(STDFLAGS) $(DBGFLAGS) $(PERFFLAGS) $(USER_C_FLAGS) Why will /Oy- be set ? Will there be any important meaning in setting /Oy- ?

    - WDF DMA use Hi. I'm designing a device driver that interacts with a master PCI DSP. I have read the documentation regarding the DMA abstraction and have some questions. The way that the DMA will work is packet-based mode, and packets will be 4KByte. Packets will be allocated by a user mode process, and an MDL will be built to describe this packet. Although the packet size is equal to a page size (32 bit OS) it might be fragment to several locations on the physical memory. A scatter\gather list will hold the description of physical address per fragment. The questions are: 1. What is the size of the smallest fragment? Will it be a byte? 1a. Can I assume what will be the number of fregamnts for 4096 bytes packet (reminder - it was allocates in a user mode application)? 2. Can I set the number of fragments and size? 3. If I set the trasfer length to be 4096 bytes and my packet size is 4096 bytes will a transaction contain one transfer? 4. If the DSP interrupts when a trasfer is completed, however it interrupts in other occasions, can the driver tell the difference? Can I write some logic in the DPC (ISR of course cannot tell the difference) in order to destingwish between two "reasons" of DSP interrupt? 5. Will a 4096 bytes Thank you in advanced for your help!

    - How to progamatically do a USB "soft eject" like explorer Windows explorer allows for a soft eject feature for USB drives that I would like to recreate in my program. This is useful for USB drives where a compact flash is inserted and removed but the USB drive remains connected to the PC. Does anyone know what functions are involved to accomplish this? I have seen code which accomplishes the hard eject (removing the entire USB device) but not the soft eject which only flushes the cache.

    - Re: No UINumber being assigned to PCI attached MPS devices in Vista Eliyas, The UINumber is correctly reported on XP. The same computer, BIOS and adapters cards are used in both instances but with different boot drives. The system uses PCI and PCI-X buses. Should there be a difference between XP and Vista? Seems like a bug... We use the UINumber to show the physical position of Adapter cards in systems we ship out. The user can then distinguish between multiple Adapter cards installed in the same system, configure the cards, attach cables, etc.. Needless to say, we will continue to ship our product with XP until we can get everything working properly and with the same performance.

    - Question regarding COM ports I'm trying to use a call to: l = ComDBGetCurrentPortUsage( HComDB, bufBits, 256, CDB_REPORT_BITS, pMaxPortsReported ); to determine if a USB serial port device is plugged in. Before plugging in the device, the device manager reports that I have 2 COM ports and 2 printer ports. After plugging in the device it reports 3 COM ports and 2 printer ports. However, before plugging in the device, a call to ComDBGetCurrentPortUsage fills in the bit array with 05 00 00... and after the call it still returns 05 00 00... (for COM 1 and COM 3) How can I determine if the USB COM device has been plugged in and if it has, what number has been assigned to it? It returns these values even if I powered up with the device unplugged. The call to ComDBGetCurrentPortUsage is in a dll written in 'C++'. The call to the dll is from a routine written in Visual Basic. Thanks for your help -- Regards, Dean Tag: Developing a device driver for a WiFi device Tag: 95315

    - WdfUsbTargetDeviceSendControlTransferSynchronously from TimerExpired function causes access violation I'm currently writing a KMDF based driver that will upon insertion of a USB device, download firmware to it and then reset the USB bus causing re-enumeration. I'm not entirely clear on the best way to implement this, my current plan is as follows: * From EvtPrepareHardware, I start a timer which causes TimerExpired to be called * In TimerExpired, I do a USB control transfer to check device state, upload a block of data and then set another timer. I thought this should be working, but I'm running into an access violation somewhere in the USB stack, and I'm not sure how to debug this further. When I call this function from EvtPrepareHardware itself, everything works fine, but calling it from TimerExpired causes the access violation. The call stack at that moment is as follows: (using KMDF 1.5) nt!DbgBreakPoint Wdf01000!imp_WdfUsbTargetDeviceSendControlTransferSynchronously+0x186 mydriver!WdfUsbTargetDeviceSendControlTransferSynchronously+0x29 mydriver!TimerExpired Now I have two questions: 1. Should I be using this design or would you suggest a different way? (the protocol requires me to sleep every now and then, and since you can't just use Sleep() I decided to go for the design as described). 2. What could be causing the access violation? Is it not allowed to call USB stack functions from TimerExpired? My TimerExpired function looks something like this: VOID TimerExpired(IN WDFTIMER Timer) { NTSTATUS status; WDFDEVICE Device; PDEVICE_CONTEXT pDeviceContext; WDF_USB_CONTROL_SETUP_PACKET thePacket; BYTE buf[16]; DWORD len, nbytes; WDF_MEMORY_DESCRIPTOR memoryDescriptor; Device = WdfTimerGetParentObject(Timer); pDeviceContext = GetDeviceContext(Device); WDF_USB_CONTROL_SETUP_PACKET_INIT_CLASS( &thePacket, BmRequestDeviceToHost, BmRequestToInterface, 0x05, 0, 0 ); pDeviceContext = GetDeviceContext(Device); WDF_MEMORY_DESCRIPTOR_INIT_BUFFER(&memoryDescriptor, (PVOID) buf, *len); status = WdfUsbTargetDeviceSendControlTransferSynchronously( pDeviceContext- >WdfUsbTargetDevice, WDF_NO_HANDLE, // Optional WDFREQUEST NULL, // PWDF_REQUEST_SEND_OPTIONS &thePacket, &memoryDescriptor, // MemoryDescriptor &nbytes); // BytesTransferred } Tag: Developing a device driver for a WiFi device Tag: 95314

    - [problem in installing the KMDF sample driver in windows XP] I am having a problem installing the KMDF sample driver in windows XP operating system. i am using the WinDDK/6001/ windows XP x86 checked build environment for building the driver sys file. it will create the automatic inf file . this inf file has Coinstaller.Section which is specifies the WdfCoinstaller01007.dll file. WDK provides this file in WDK/redist directory . i copied .inf file .sys file and WdfCoinstaller010007.dll file in one directory . using the control panel add new hardware i have installed the driver. but this is not installed the driver properly. it has given this error message: "The specified resource type cannot be found in the image file". if any body have idea to solve this error give suggestion: thanks is advance. sulibsp Tag: Developing a device driver for a WiFi device Tag: 95313

    - KMDF driver for XP Hello All, I am using Windows XP SP1. I have downloaded the WDK 6001 with KMDF version 1.7. when I tried to load the sample driver "echo" or "toaster", the following error message is generated "The specified resource name cannot be found in the image file" Release notes says that, the sample drivers provided with KMDF 1.7 can run on Windows Server 2003 / Vista. Even a simple driver with DriverEntry with only KdPrint() on KMDF with CoInstaller of 1.7, same error message is coming. Please let me know how to solve this problem. Also, whether can I use this WDK / KMDF version for XP driver development? -Kans. Tag: Developing a device driver for a WiFi device Tag: 95305

    - How to get the packet of KS_TVTUNER_CHANGE_INFO in Analog tuner Dr Hello: I am studying analog tuner driver. I start from DDK Sample "anlgtuner". In graphedt, it can play. When i want to change the channel, it stops work with error code "Incorrect function 0x80070001". It seems that the function to receive KS_TVTUNER_CHANGE_INFO is missed in driver from DDK doc: when the tuner switches from one channel to another, A minidriver must propagate a tuning packet from its tuner filter, through the crossbar filter, and then into the analog video input pin on its capture filter. This packet is only available in user mode until it reaches the capture filter. The minidriver receives this tuning packet as a KS_TVTUNER_CHANGE_INFO structure on the analog video input pin of the minidriverâ??s capture filter. I add AVStrMiniPinProcess callback routine in KSPIN_DISPATCH of the video input pin of the capture filter. But this routine was never hit and error still occured. So how to get the packet of KS_TVTUNER_CHANGE_INFO in Analog tuner Driver? Could somebody point me out? Thanks Max Tag: Developing a device driver for a WiFi device Tag: 95304

    - make USB hub easily identifiable Some quick background: We are making a set of USB medical data collection devices. Most commonly, they will be packaged together and permanently connected to a USB hub in the same case, however they will also be available as independent devices. I need to know whether a unified device is connected or a bunch of individual modules, among other things the user should be informed if one of the devices fails in the unified collection. The hub chip uses an EEPROM that specifies the VID, PID, and device number. How can I use the standard USB hub driver for our device but tag it in a way I can detect while enumerating devices (using e.g. SetupDiCreateDeviceInfoList, SetupDiGetDeviceInterfaceDetail)? It would be best if I can control the name of the device which appears in Device Manager after the driver loads, but as long as I can distinguish our hub+devices group from a device attached to a standard hub it will be fine. Should I put in a different VID/PID pair (we can get numbers assigned) and write an INF that loads the Microsoft driver? Where would I find an example of that? Or would it be better to leave the VID and PID alone and change the device number? Any advice would be appreciated. Tag: Developing a device driver for a WiFi device Tag: 95268

RegisterClientSettings UnRegisterClientSettings OpenClientRegistryKey RegisterClientDriverID So using those functions I can access the registry. I need to get the string path of the handle returned by OpenClientRegistryKey function. This is because I need to pass it to ActivateDevice function. So 1. How can I get string registry path from handle of the registry ? 2. I call UnRegisterClientSettings function inside USBDeviceAttach function. But it fail is there any reason ? Please help me.

    - Authenticode driver signing on Windows 2003 Hi, I 'm using the signtool in Win2003 R2 DDK to sign a network driver for Win2003 with authenticode using a valid VerigSign class 3 certificate. The sys file and CAT file have been embedded a vaild signature in "Trusted root Certification Authory" and "Trusted Published" store. When I install the driver, it show a "unsigned driver" warning, and appear as "Not digital signed" in Device Manager. Is there any additional requirement for the certificate or driver to use authenticode driver signing on Windows 2003? Thanks Tag: Developing a device driver for a WiFi device Tag: 95234

    - Common buffer allocation for DMA in WDF 1.1 I have updated a WDM function driver to WDF,the DMA function(Our device act as bus master) was added into.The whole project works well but there is a problem that I have no idea about.When start my device in the device manager,if the DMA common buffer is too big for system (system can not find a big enough continus physics memory),the WdfCommonBufferCreate failed,then the OS crash with a blue screen.The followwing is my codes: WDF_DMA_ENABLER_CONFIG dmaConfig; WDF_DMA_ENABLER_CONFIG_INIT( &dmaConfig, WdfDmaProfilePacket ,//Profile was WdfDmaProfilePacket DevExt->MaximumTransferLength ); TraceEvents(TRACE_LEVEL_INFORMATION, DBG_PNP, " - The DMA Profile is WdfDmaProfilePacket ");//Profile was WdfDmaProfileScatterGather64Duplex status = WdfDmaEnablerCreate( DevExt->Device, &dmaConfig, WDF_NO_OBJECT_ATTRIBUTES, &DevExt->DmaEnabler ); if (!NT_SUCCESS (status)) { #if DBG KdPrint(("ADX: WdfDmaEnablerCreate failed with status %x\n",status)); #endif return status; } #if DBG KdPrint(("ADX: WdfDmaEnablerCreate finished with status %x\n",status)); #endif } // // Allocate common buffer for DMA // // NOTE: This common buffer will not be cached. // Perhaps in some future revision, cached option could // be used.

    - COM port naming Hi, I am working on a WDF serial port driver wherein I create a virtual serial COM port and I need to have the COM port number of my choice always whenever I load the driver. For this I had created a device map and written that value using RtlWriteRegistryValue(). By doing this I am able to get the COM port number of my choice in the Hyper Terminal, but the device manager is showing the COM port number which windows has assigned. Now I want the COM port number of my choice to be reflected even in the Device Manager. Can anyone of you please help me in resolving issue? Thanks in advance.

    - PsSetLoadImageNotification changed ? In my driver I make a call to PsSetLoadImageNotification () and get a callback as expected. One of the params in the callback is the ProcessId. I'm saving the processId to note when a particular (say, my) user mode component is loaded so that when I see Ioctl's I can assure myself that I know who I'm talking to. In XP this worked fine, the same code in Vista does not: Once the user mode program is running , I dump out the process using !process 0 0 in windbg which indicates that the ProcessId that I got in my callback is that of the Parent CID not the guy I'm loading Of course, when I do PsGetCurrentProcessId() in my DeviceControl routine, I get the process's Id, and I never recognize my particular user mode component. Any ideas, beyond of course going back to an XP box and making sure that the behavior I think I saw is really happening there? -- Gak - Finecats Tag: Developing a device driver for a WiFi device Tag: 95222

    - INF file processing API functions Hi, I am trying to understand why is there a need for INF file processing functions when, for example, we can use standard C/C++ File IO functions. I have a few questions. What is advantage of using INF file processing API such as SetupOpenInfFile? And what is proper method of chain of actions needed to properly read a Hardware ID of a device from INF file if you are searching through a whole directory full of INF files? Suppose, device belongs to NET class and we want to match a network adapter Hardware ID to the one present in some INF file. My guess is we can eliminate any INF file that does not belong to NET class. Need some guidance on how to properly do this. More details can be provided if need be.

    - DeviceIoControl blocks even in Overlapped I/O mode? How is this possible? Could someone please clarify the term "Overlapped I/O" (or "Pending I/ O")? I thought that if I implement and use it properly, DeviceIoControl() would never wait/block, leaving it instead to a WaitForMultipleObjects() or WaitForSingleObject() down the line. However, in a recent buggy driver implementation of mine I managed to make DeviceIoControl() block in a write operation... How is this possible? I thought that the "no wait intelligence" (in overlapped mode) is built into the DeviceIoControl() code and not dependent upon the device driver implementation. Have I misunderstood? What am I missing? Thanks, Don Tag: Developing a device driver for a WiFi device Tag: 95217

    - How to develop UVC webcam driver on win2k Dear all, As our customer request driver of UVC webcam for the early Windows OSes, I need to develop a driver for UVC webcam on Win2K. But I have some questions just as below: 1 Can MS USBCAMD minidriver or AVStream achitecture support UVC webcam driver development? I means if the UVC request/command can be sent to Webcam successfully, or some special trick is need to get/set request thru interface. 2 Is there any special request for the webcam hardware? in other words, besides UVC HW logic, another no-UVC HW interface for custom driver? 3 What is right sample code to kick off UVC webcam driver? Any idea is appraciated. Thanks in advance! Tag: Developing a device driver for a WiFi device Tag: 95206

    - KeWaitForSingleObject() can only reach 0.01sec timeout I am using the KeWaitForSingleObject() to do delay in my kernel mode driver like following: LARGE_INTEGER nWaitTime; nWaitTime = RtlConvertLongToLargeInteger(-1000 * 10);// I need 0.001sec KeSetTimer(&fdoData->kTimer, nWaitTime, NULL); KeWaitForSingleObject(&fdoData->kTimer, Executive, KernelMode, FALSE, NULL); But when I use DbgView to catch the actual delay, I found that it can only reach 0.01second at most and cannot satisfy my requirement, 0.001sec.

    - USB Phone driver question Hi I've got some USB phone sample from vendor, it will be installed by Windows XP after I plugged in USB port , and I saw it use the system usbaudio.sys . I need to create some ks filter properties and events as a vendor's own USB phone driver . Is it possible we base this driver on Windows system audio driver ? I've researched that a custom audio driver can use portcls driver ( collection of port drivers) and adapter driver ( collection of miniport drivers ) . Should I use usbaudio.sys as adapter driver ? If this way ok how can I make its portcls driver ? I did not find sample code like portcls.sys from DDK . Tag: Developing a device driver for a WiFi device Tag: 95198

    - Failed to load driver on Vista I have an application that works with two particular drivers, one is loaded on boot and second is loaded when my application is working. I use the first driver to load and unload the second driver using ZwLoad/ UnloadDriver. Everything works fine on Win2K and XP but I encounter some problems in Vista. Sometimes I get error 0xC0000034 upon ZwLoadDriver of my second driver. I looked for my drivers and devices in the system, but monitors such as DeviceTree or WinObj do not show any of them. On the other hand, from a full memory dump I can see my second driver loaded. >From some reasons that I can't explain, I see that when I run my application "as administrator" and immediately close the application everything suddenly get back to track. When I run my application as administrator I even do not attemp to load the driver. Of course, after computer restart the application starts to work fine as well. It is important to mention that both drivers are properly signed. Any help is very appreciated. Tag: Developing a device driver for a WiFi device Tag: 95189

    - LNK2019 Error with Win Server 2003 Checked x64 I've written a driver and have successfully built it using WinXP Checked Build. When I compile the same project with the Windows Server 2003 Checked x64 tools, I get "LNK2019 - unresolved external symbol <blah blah> referenced in DriverEntry". I'm linking in .lib files, declaring them as "external" in the driver code. As I said, the same code and files compile perfectly with the WinXP Checked Build compiler. I'm getting the LNK2019 unresolved errors with the Windows Server 2003 Checked x64 Build compiler. Any help and insight would be appreciated.

Is there any command to know about the reason of this soft reset? Also, which command we can use from RNDIS device side to tell the host to restart the RNDIS initialisation process again?

    - AVStream PresentationTime The DDK docs say, for IKsReferenceClock::GetTime, "Do not call this method when obtaining a timestamp for the PresentationTime member of KSSTREAM_HEADER. Instead, call IKsReferenceClock::GetCorrelatedTime in this situation." However, every one of the samples uses GetTime, and none use GetCorrelatedTime. Any insight? Or does it just not matter very much? Cheers, --mkj Michael K. Jones Stone Hill Comsulting http://www.stonehill.com Tag: Developing a device driver for a WiFi device Tag: 95169

    - No UINumber being assigned to PCI attached MPS devices in Vista I have an MPS driver which relied upon the UINumber to identify which attached device was being addressed. Past OS's apparently assigned this attribute the PCI slot location of the MPS board. However, it appears as though Vista no longer performs this assignment. Is the a different mechanism that can be used which works in 2000, Server 2003, and XP? Tag: Developing a device driver for a WiFi device Tag: 95168

Hi...
I need to interface a WiFi device that defines its own protocols with a
Windows PC. I've done some Googling and a found a set of Windows WiFi APIs
that I think I can use.
Do I need to build a device driver? ( The device will never interact
directly with the kernel ) And what would be best IDE to use?

Thanks in advance...
