 - Performance problems 1394bus.sys Any suggestion on the following topic please: I am working on a project for a motion control architecture based on the 1394 bus. We are using the Windows XP 1394 driver stack and built our own custom function driver. Since the application is timing critical we developed methods to see what is going on in time inside this driver. We need continuous isochronous transport so we are reattaching buffers inside the driver. Strangely enough the time needed for reattaching (and especially detaching) buffers seems to increase over time. From about 30us for 100 buffers at the beginning of the transfer to 150us after a few seconds. Size of the buffers does not seem to matter, the number of buffers, however, does. This is a serious issue for us, since reattaching buffers now claims a lot of our system resources (CPU load). Is this a known problem? Is there a way to avoid this problem? What causes the 1394bus driver to spend so much resources on detaching / attaching? I will be glad to supply additional information if needed. Thanks in advance! -- Jack Goossen Tag: Default USB interface Tag: 54667

 - Trying to replace NdisMAllocateMapRegisters() with NdisMInitializeScatterGatherDma() So I figured that I would call NdisMInitializeScatterGatherDma() as the docs say that should let us get shared memory. But I get zero shared memory when I use NdisMInitializeScatterGatherDma() Here is my setup: ==================================== #ifdef MAPREGISTERS Status = NdisMAllocateMapRegisters(pAdapter->D100AdapterHandle, 0, NDIS_DMA_32BITS, // pAdapter->NumMapRegisters, 1, pAdapter->MaxPhysicalMappings); #else Status = NdisMInitializeScatterGatherDma( pAdapter->D100AdapterHandle, FALSE, 4096); #endif ==================================== When I undefine MAPREGISTERS I don't get any shared memory. Yes I set the bus master bit in NdisMSetAttributesEx() Yes I get NDIS_STATUS_SUCCESS from either call. Any ideas? Tag: Default USB interface Tag: 54658

 - How to include space in directory path for launching help in a MFC program Hi, I have a MFC program. I have a help file (.chm) which I launch when the user clicks on Help option. It works fine if I put the .chm file in a directory path which has no spaces. However, I do want to put this file under "Program Files\....." If I put under this directory path, it won't find the .chm file and the help will not launch. How do I include a space in the directory path ? Thanks, _SK Tag: Default USB interface Tag: 54655

 - UNIDRV add custom paper sizes I am attempting to add custom paper sizes to a UNIDRV printer driver from a ui plug-in dll. Adding the paper sizes is straightforward usig AddForm. However the array of paper size OPTPARAM does not include this new size until the document property sheet is closed and then re-opened. I would like to have this array re-initialized with the newly added form without having to close and re-open the dialog. I have attempted to manually reallocate the array and add a new OPTPARAM to the array pointed to by the pOptParam member of the paper size OPTTYPE structure, although this seems to work it does not save the new form in the devmode correctly. Any ideas on other ways to accomplish this task? Tag: Default USB interface Tag: 54652

 - PnP INF File Question I have a VERY strange situation I need to solve. We mfg a serial hardware device for downloading data out of a reader. The downloader contains PnP code; when you place the device on the serial port, reboot or run the add device wizard, everything works fine. However, this PnP device does NOT require a driver, so we wrote the below INF file which seems to work fine. There is one catch I would like to solve, and perhaps someone knows how to do this. When we install the INF in the INF folder, we would expect the process to NOT query the end-user. This is NOT the case; the process is querying the user in all cases. Why is that? Is there something we need in our INF, or is it because we do not have a signed driver that is required? We would really like to avoid having the user have to constantly browse to the INF when it is already local to their PC. Any help would be most appreciated. Thanks!

 - zwwritefile return STATUS_INVALID_PARAMETER Hi, Sometime I receive the value STATUS_INVALID_PARAMETER from ZwWriteFile, my device work in Win 2000/XP. I create a file with ZwCreateFile (I use the OBJ_KERNEL_HANDLE) I call ZwWriteFile from a WorkItem, so I'm at Passive_Level. This is my code: // Create the file and in hFile I have the handle ntStatus = MyCreateFile (&fileNameUnicodeString, &hFile, FILE_OVERWRITE_IF); After I queue a WorkItem for write in my file // My code in WorkItem: // I use PagedPool because I'm at IRQL PASSIVE_LEVEL (WorkItem) pNewbuff = ExAllocatePool( PagedPool, BytesAvailable); ntStatus = WriteFile (hFile, (PVOID) pNewbuff, BytesAvailable, &dwBytesWrite2, NULL); Sometime ntStatus = STATUS_SUCCES, when I stress my device ntStatus is STATUS_INVALID_PARAMETER Do you have an idea ? These are my function MyCreateFile and WriteFile: NTSTATUS MyCreateFile (IN PUNICODE_STRING pUniFileName, OUT PHANDLE p_ntFileHandle, int TypeDisposition) { NTSTATUS ntStatus; OBJECT_ATTRIBUTES oa; IO_STATUS_BLOCK ioStatus; InitializeObjectAttributes( &oa, pUniFileName, OBJ_CASE_INSENSITIVE | OBJ_KERNEL_HANDLE, NULL, NULL ); ntStatus = ZwCreateFile( p_ntFileHandle, GENERIC_READ | GENERIC_WRITE | SYNCHRONIZE, &oa, &ioStatus, NULL, FILE_ATTRIBUTE_NORMAL, 0, TypeDisposition, FILE_NON_DIRECTORY_FILE | FILE_SEQUENTIAL_ONLY | FILE_SYNCHRONOUS_IO_NONALERT, NULL, 0 ); if( !NT_SUCCESS( ntStatus ) ) { DbgPrint(("Could not creAte file, status: %x\n", ntStatus )); } else DbgPrint(("file create handle: %x\n", *p_ntFileHandle)); return ntStatus; } NTSTATUS WriteFile (HANDLE hFile, PVOID lpdat, DWORD size, DWORD *dwBytesRead, PVOID p1) { NTSTATUS ntStatus; IO_STATUS_BLOCK ioStatus; ntStatus = ZwWriteFile (hFile, NULL, NULL, NULL, &ioStatus, lpdat, size, NULL, NULL); *dwBytesRead = (DWORD)ioStatus.Information; return ntStatus; } Best regards Gian Tag: Default USB interface Tag: 54632

 - Restricting access to USB devices Hi All, We have two requirements in our project, it is related to USB devices in WDM. We don't have much idea regarding the USB devices and USB class drivers. So I hope I can get some guidance from this group regarding my problem. Operating System : Windows XP Embedded. One requirement is, support only few specific USB devices in the machine. All other USB devices should be blocked. The following are the USB device classes to be supported in the machine. a. Human Input Devices (HID), b. Chip/Smart Card Interface Devices (CCID) c. Various Mass Storage class devices (MSC). E.g.. Smart Card d. Audio and Modem devices Our Current Idea for implementing this ---------------------------------------------- Remove the class drivers of the classes of devices to be blocked. Some of the classes we identified to be removed are listed below. a. Printer Class (usbprint.sys) b. Communications Device Class (mdismp.sys) c. Imaging Class (usbscan.sys) d. Hub Device Class (usbhub.sys ) This can be done while configuring embedded Windows XP. Will be there any problem if we remove these drivers ? The second requirement is that the read/write access to the supported USB devices should be controlled. i.e.. if it the permission set is READ_ONLY, only read access will be allowed. Our current Idea for implementing this ------------------------------------------- 1. Write a USB filter driver ( Say, usbmon.sys) 2. Install it as a 'class upper filter driver' to the required classes of devices. a. Human Interface Device (HID) Class. (hidclass.sys) b. Audio Class (sysaudio.sys) c. Mass Storage Class (usbstor.sys) 3. Export a IOCTL from usbmon.sys so that user mode applications can control the read/write operations to . Is there any better idea for implementing these things. Are we in right direction? Please advice. Thanks in advance, vasanth. Tag: Default USB interface Tag: 54630

 - WDM Wizard Walter Oney Hello, I am trying to develop a WDM driver with the WDM Wizard that comes with Walter Oney´s Book, I am able to create a project without or with generic.sys, and also I can compile them but when I install it in the system using the .inf file the Device Manager show that there is a problem with my driver, and the message is that: "This device cannot start. (Code 10)" I did not make any change in the walter oney´s wizard generated driver, so I guess it should work, without any functionality but I just want to see that is ok. There is something that is necessary to do before compiling, like adding some code, because I just have used the fixproj.exe that the book says to execute. If you have any idea please tell me. regards Guilherme Francisco Mallmann Tag: Default USB interface Tag: 54619

 - Set the postscript dirver option TTDownloadFormat ("TrueType Font Hi, I asked this question in 3 other newsgroups (microsoft.public.windows.print, m.p.w.print_fax, m.p.w.printing), but didn't get a reply about what I needed, So I'm trying here again. Any pointers to other newsgroups that may help will also be appreciated. I'm trying to write a program that creates a printer, with a driver based on the MS PS driver and a ppd I supply (it has to run under windows 2000 and XP). If I do this, the printer created has an advanced option "TrueType Font Download Option" (in XP under the printers 'printing preferences', then 'Layout/advanced/Document options/PS options/TrueType Font Download Option'). I'd like to set this option to 'Native TrueType' when creating the printer (or right after it). I have found no way to do this short of looking at which bits in the devmode's driver specific portion change and redo that change using GetPrinter/SetPrinter (I understand from what I read however that fiddling with the driver specific portion of devmode like that is a very bad idea). There seems to be a way to set this through IPrintCoreUI2::SetOptions, at least that's the only 'SetOptions' I can find that this article could be talking about: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/graphics/hh/graphics/pscript_9c9f919f-341e-45bb-ab32-a8e215cecb41.xml.asp However, from what I understand, this call is designed to be called from a printer property sheet, and structures made available by the system that calls the property sheet (first parameter: "poemuiobj Points to the current context, an OEMUIOBJ structure.") Does anyone know a way to set this option? ---clarification based on earlier answer--- Note that this is not the dmTTOption memeber of DEVMode, that sets 'Layout/advanced/graphic/TrueType Font' (which has options 'Download as Softfont' or 'Substitute with device font'), while the option I'm looking to set is under 'Layout/advanced/Document options/PS options/TrueType Font Download Option' (which has options 'Automatic', 'Outline', 'Bitmap' and 'Native Truetype'), but only for printers that use the microsoft PostScript Printer Driver (Pscript, documented at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/graphics/hh/graphics/pscript_ccdc3e30-0b44-4ada-b51a-8c0d0bfd5997.xml.asp). It is specific to Microsofts PostScript Printer Driver (I think), and is described as "Driver features are non-PPD features that are synthesized by the driver" here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/graphics/hh/graphics/pscript_a64f2cd3-6775-4121-98b1-7470c302574f.xml.asp Thanks for any help anyone can give me.

 - Microsoft please help! NDIS Intermediate driver bindings We have written an NDIS intermediate filter driver that binds to TCP/IP at its upper edge and a network adapter at its lower edge. If another intermediate filter driver is installed as well, the new driver either sits above our driver or below it in the stack. Is there a way that I can force our driver to always be above the other intermediate - we always want to see the traffic coming directly from TCP\IP and not from some other intermediate driver above that might be above? I suppose the question I'm asking is, is there a way to control the ordering of intermediate drivers when there are several installed on one system? Tag: Default USB interface Tag: 54614

This usually indicates problem with the hardware itself or with the device driver programming the hardware incorrectly. If the kernel debugger is connected and running when watchdog detects a timeout condition then DbgBreakPoint() will be called instead of KeBugCheckEx() and detailed message including bugcheck arguments will be printed to the debugger. This way we can identify an offending thread, set breakpoints in it, and hit go to return to the spinning code to debug it further. Because KeBugCheckEx() is not called the .bugcheck directive will not return bugcheck information in this case. The arguments are already printed out to the kernel debugger. You can also retrieve them from a global variable via "dd watchdog!g_WdBugCheckData l5" (use dq on NT64). On MP machines it is possible to hit a timeout when the spinning thread is interrupted by hardware interrupt and ISR or DPC routine is running at the time of the bugcheck (this is because the timeout's work item can be delivered and handled on the second CPU and the same time). If this is the case you will have to look deeper at the offending thread's stack (e.g. using dds) to determine spinning code which caused the timeout to occur. Arguments: Arg1: 824fd6a0, Pointer to a stuck thread object. Do .thread then kb on it to find the hung location. Arg2: 82675ce0, Pointer to a DEFERRED_WATCHDOG object. Arg3: 8266bd48, Pointer to offending driver name. Arg4: 00000001, Number of times this error occurred. If a debugger is attached, this error is not always fatal -- see DESCRIPTION below.

 - PREfast: pragma prefast The PREfast documentation seems a bit lax on the usage of pragma prefast for inhibiting display of individual warnings. It only shows how to inhibit Compiler warning 4068, but does not show how to specify the PREfast warnings. How do I use it in my source code? Can I use the pragma statements to turn a warning off before and off after a call to a function or macro (like IoSetCompletionRoutine) that always generates a PREfast warning (314, in this case)?

 - How to use 2 USB mice independently and simultaneously? Hello Experts :-), I am writing a Windows XP fun-application and would like to use 2 INDEPENDENT USB mice SIMULTANEOUSLY as input devices. Therefore, I understant, I have to go below OS mouse events (below mouse driver) as they all appear as coming from a single mouse. So, I tried to go through reading a HID-based device as described in the DDK. But I cannot get any data from a HID-based mouse. The reason is that I cannot even open a file by CreateFile (cannot get the handle to the mouse) cause this returns an Invalid_Handle_Value. What I think happens is that OS open a file earlier (at installing the device) capturing the handle and that only one file handle can be open to a HID based device, so the OS is the only one to be able to readall the HID input reports. Am I right? Or is ther a way to get input from mouse at HID device level? I see some solutions if I cannot access HID mouse from HID driver level: 1. At Windows level if there is some differentiation possible to see from which mouse the particular event came. But I doubt whether it is possible. 2. There is some way to overtake a handle to HID from OS. Whether stealing at the moment the device is connecting and drivers are interconnecting, or after the device is already connected. Somehow. I do not have a clue ho to do this. Any tips guys? 3. There is a filter driver needed below HID driver (HID mini driver? USB driver?), from where the mouse reports could be stolen from OS, or maybe forked? Would like to hear your opinion on that issue, Any help? Example code?

The instruction that causes the AV is: 006472E0 832D907FAF0001 sub dword ptr [0x00AF7B90], 0x01 The exception is: Access violation at address 006472E0. Write of address 00CC7B90. 0xAF7B90 is a variable in my BSS segment. 0xCC7B90 is outside of my address space. The code is in the initialization section of a 3rd party component which is called from the startup code, well before any of my application code executes. What I don't understand is how the above instruction could cause a write to an address different from the specified address. It seems suspicious that the addresses differ only in the 2nd byte. Thinking that I might have a hardware problem, I've swapped the CPU and memory in my computer, but the problem persists. I don't have a spare motherboard to swap in. This problem comes and goes depending on the address of the above SUB instruction. If I comment out a single line in my code, the SUB instruction appears at address 0x6472CC rather than 0x6472E0, and the instruction executes properly, subtracting 1 from the DWORD at 0xAF7B90. WinXP, SP1a+. TIA! Tag: Default USB interface Tag: 54578

 - Packect Filters/Drivers Hello all Thax for the suggestions if any. The work is meant for Windows CE. Some of the questions are generic to all of Windows. Ethernet, WAN ============= Assumptions about NDIS hook filter driver: a. Ndis Hook driver resides between Tcpip.sys and Ndis.sys (in NT/2K ) b. Replace NDIS.SYS function pointers(addresses) with new hook function addresses. c. So NDIS.SYS calls these new functions and new ones can call the original functions etc. 1. Under windows CE is this Ndis hook driver possible? (I guess YES. but usually replacing the NDIS.SYS addresses etc. might cause system exceptions in CE. doen't it?). 2. If yes, then Ethernet is okay. Meaning, it sits between tcpip and Ndis 3. But for WAN cases in CE, TCP/IP talks to PPP(No Ethernet emulation like NT/2K). PPP is a NDIS protocol driver in CE. So how do you hook this driver between these 2 protocols drivers? 3. If its not possible, Does a TDI driver type work in WAN case? Bluetooth ========= In case of bluetooth, different profiles use different stack paths( at least in CE ) Examples 1. A Serial port application goes thru RFCOMM to L2CAP 2. PAN NDIS driver goes to L2CAP directly. (I think TCP/IP talks to PNDIS). 3. LAN access profile goes thru TCP/UDP --> IP --> PPP ---> RFCOMM ---> L2CAP. How would one control bluetooth activities? a. Since more than 90% of the data flow goes thru L2CAP(rare cases hit HCI directly), Is there a way to develop a driver just above L2CAP and analyze the packets? Of course this may not be the useful place for encrypted packets, but we can control some. b. HCI Stack Extension Layer could be a solution?. If we develop one of this over L2CAP, could we selectively block the traffic? c. Any kind of hooking filter or TDI driver is helpful for this traffic? Thanks for the help and suggestions.

 - 16 Bit PC Card and resource problem Hi, This issue might have already answered many times on this post. On some laptops I cannot install the PC Card and as per the initial investigation looks like to me no memory available to address by 24 bits. I have tried modifying the inf to specify (D) for MemConfig and that maps the device on the higher address range addressable by 32 bit and gets installed properly but since it is a multifunction card I cannot get the functional device working, I get error 10. Once I specify (D) do I need to do anything else so that system and PC Card controller will be able to map the addresses properly? As well as is there any other workaround? - SK Tag: Default USB interface Tag: 54575

 - Passing a Synthetic Write to a lower level Filter driver Hi folks, I am fairly new to the WDM Driver world. I have written a lower filter driver to view some serial port traffic,and now I want to be able to write to the driver my data - vs just passing down data from upper filter drivers. I got that working using iobuildasynfsdrequest with the MJ_WRITE ,and the lower Serial.sys driver responds with the correct response too. However - here's the problem - if any other application,eg hyperterminal has this port open,then that app also gets the writes from my driver. I tried queueing the IRPs from the above filters too-that did not work. So my question is this:how do I prevent my writes being "read" by other upper filter drivers? Have I layered my driver wrong? Any help appreciated.Thanks in Advance Jack Tag: Default USB interface Tag: 54573

When I return STATUS_SUCCESS in the completion routine the pc reboots immediately without showing a blue screen.

 - 1394 Surpise Removal I have a two 1394 cameras setup and I run into an error which causes my application to never exit the task manager. The application goes through the entire shutdown process (even the destructor of the main frame) but the process seems to still be running. I cannot kill the process but it eventually dies (~10 minutes or so). Disconnecting both devices at the same time while the application is running causes the following behavior: 1) WM_DEVICE change leads to a getDeviceList (using the setup api). 2) Setup API returns 1 device present which is technically not correct. 3) My app tries to do a REQUEST_ASYNC_READ to determine if the device is valid. 4) This 1394 driver fails the submit to lower device with an error of NO SUCH DEVICE. 5) Because I did this read, the application does not shutdown properly. Does anyone have any ideas for things that I can look at? Thanks in advance, Mukul Tag: Default USB interface Tag: 54561

 - A doubt on handling IRP's I am writing a storage filter driver and need to keep track of all read/write requests. So for every device (volume) that I monitor, I have a small cache in the device object (in device extension). As soon as a read/write request comes in, I add this info to this cache. I need to synchronize access to this cache. So I have a mutex (wont work on multiprocessor but this is just a demo) which guards the code that manipulates the cache. All this is working fine but I am kind of doubtful about this access to the cache. Since I am adding this synchronization object to keep track of the IRP's, I am kind of slowing down the behavior because of the synchronized access to the cache. Every Read/Write request will have to wait to access this cache. So I am kind of skeptical about this design. Is there a better way to do this? I feel that the IRP's being "tunnelled" thru will affect overall performance. Thanks, Gary. Tag: Default USB interface Tag: 54503

I am wondering if OpenHCI will handle data buffers bigger than the max packet size on the pipes. It appears that it also does not like the buffer (512 bytes) I pass to the interrupt pipe (with max packet size of 8 bytes). The usbport.sys, which my driver calls on XP, handles bigger buffers just fine. Now MS document on UsbBuildInterruptOrBulkTransferRequest does not put size limit on the data buffer used. However, I am also highly suspicious that this bug happens under special circustance--a bug like this would have been spotted long time ago. // routine to init and send URB // Note: the call to read the response failed with STATUS_INVALID_PARAMETER--the input buffer size ( // pReply->BufferSize is 0x120 (while my max packet size for the input pipe is 64 bytes).

 - Detect video rotation Many recent notebook computers have added various features to rotate the display either to switch between portrait and landscape, or to rotate 180 degrees (usually, the argument for this is that in Japan, they like to sit across the table from their customers and flip the display so that it's face up to the customer but upside down to them). Detecting the difference between portrait and landscape mode generically is pretty easy (if nothing else, you can look for a WM_DISPLAYCHANGE message and see whether X or Y is bigger). However, I haven't (in a very short amount of searching so far) figured out any way to generally (i.e. not dependent on video driver) detect a 180 degree rotation. Does anyone here know whether there is a general way to detect this? -- ../ray\.. Tag: Default USB interface Tag: 54484

Dear ALL,

I am working for company, which creates high-speed USB devices using
Cypress microcontrollers. To reprogram Cypress firmware I need to send
it several specially formatted USB control requests. My goal is to
develop universal application and may be driver (if unavoidable), to
reflash our devices during testing and in the field. It would be nice
to have such application because firmware update implemented by
Cypress microcontroller in hardware and do not depend on whatever junk
we loaded it with previous time.

I figured out, that all USB devices support interface with GUID
{a5dcbf10-6530-11d2-901f-00c04fb951ed}, which is
GUID_DEVINTERFACE_USB_DEVICE. Is there any way to get anything useful
out of this device interface? I figured out, that it is exported by
usbhub.sys driver and get created even if no driver loaded for USB
device. I can open this device with CreateFile() Win32 API call, but
that is all. I tried to open this link from one of my drivers and use
the object returned by ObReferenceObjectByHandle() as lower physical
device object to send URBs to, but it didn't work.

As a last resort, I can develop USB filter driver if anything simple
would not work for me, but I am not sure if I will get access to USB
device without driver loaded.

Thanks for reading my message :) I will really appreciate any help on
the issue.

Thanks for your time,
With best regards,
Vladimir S. MIrgorodsky

the default usb device interface is ther purely for enumeration , it does
not provide any of the facilities you require. since this is your device,
there is no need for filter. load the firmware download driver, download
the firmware.
