 - HELP NEEDED: Mirror Display driver problem... Hi, I am trying to access the miniport driver from user mode, when trying to access the display driver all works fine, BUT when trying to get the miniport handle ( at user mode ) I keep getting an invalid handle with a file not found last error code... Why can this happen? The driver name I am using is found under 'HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\%DriverName%' and the same name found in the .inf file used to install the driver... What am I doing wrong here? following is a snap-shot of the code used to create the driver and the .inf file used to install the driver... THE CODE USED TO GET THE DRIVERS HANDLE ======================================= // Returns an invalid handle, GetLastError returns file not found...

 - unresolved external using standard C lib I feel like an idiot, but this is my first time trying to compile things in the DDK environment. I'm trying to use the C standard runtime function "fopen" in a driver. I've included stdio.h and the code compiles fine, but when it links, I get "unresolved external symbol __imp__fopen referenced in function..." I figured the standard C library stuff would be setup to link by default. What am I missing, and where does it go? Thanks, pw Tag: Access USB device from userland Tag: 40922

 - [802.11] Windows NDIS questions Hello, I am beginner at this subject. Sorry I if ask some bullshits. I need develop an application that detect the available access points and establish a connection. The target O.S. are Windows 2000 and Windows XP. My questions are: 1. What are the diferences among NDIS, NDISUIO and NDISPROT? 2. Must I develop a Protocol driver(like NDISPROT or NDISUIO) or it's better call directly the NDIS library functions(like NdisRequest)? 3. How can I disable Wireless Zero Configuration (WZC) service inside my application? Thanks, Claudio. Tag: Access USB device from userland Tag: 40920

 - Questions on PCI config space when ressetting a PCI board Hi, I'm developing a wdm driver under Win2K for a proprietary PCI board. Unfortunately, the board's PCI interface logic is part of a FPGA that can only be fully reset by reconfiguring the FPGA. We foresee that we need to reset our board on certain occasions and we do not want to power-cycle our system for this. Therfor, I'm implementing the following reset sequence in my driver: Because the reconfiguration of the FPGA resets the PCI config space, I start with saving this data (after having disabled the boards PCI interface). I then call PoRequestPowerIrp to force the board to go to device state D3. In the IoCompletion routine, PoRequestPowerIrp is called again to force the board to go back to device state D0 (this actually resets our FPGA and the PCI config space). In the IoCompletion routine of the second PoRequestPowerIrp, I restore the PCI config space data and reenable the PCI interface. When, in the above scheme, I use the sequence IoBuildAsynchronousFsdRequest() - IoSetCompletionRoutine() - IoCallDriver() to read or write the PCI configuration space, this completion routine is called with DeviceObject = NULL. I solve this by passing the DeviceObject via the 'context' of the completion routine. Is this normal or could I be doing something wrong here? Apart from the above problem the sequence seems to work, but I am not sure wether I should also save and restore the power management registers of the PCI config space. Or should I leave this to the pci.sys bus driver who does the actual D0/D3/D0 switching ? Also, I'm not sure that the above will work under all circumstances so I would appreciate it if anybody knows where to find some more info on stuff like this. Thanks in advance, Koen Tag: Access USB device from userland Tag: 40909

 - Basic kernel mode driver question. I have the following development workstation: Windows XP Pro, VC++6.0, DDK 2600.1106 (installed in C:\DDK\WINDDK\2600.1106), Platform SDK February 2003. As a confirmation that all of the above components are installed correctly, I compiled one of the sample projects (oemps) by doing the following: 1.. Opened an XP checked build window via the start menu. 2.. Navigated to "C:\DDK\WINDDK\2600.1106\src\print\oemdll\oemps". 3.. Typed "build -cef" 4.. The kernel mode driver KOEMPS.DLL was built and placed in "C:\DDK\WINDDK\2600.1106\src\print\oemdll\i386". My goal is to generate a random number in PSCommand method of "C:\DDK\WINDDK\2600.1106\src\print\oemdll\oemps\command.cpp" 1.. Using the VC6.0 IDE, I added the following to the pscommand method: LARGE_INTEGER time; ULONG seed; // seed value should be a global or in device extension ULONG rand; // random value KeQuerySystemTime(&time); // only do first time or in init code! seed = (ULONG) time; rand = RtlRandom(&seed); // get random number 2.. I Opened an XP checked build window via the start menu. 3.. Navigated to "C:\DDK\WINDDK\2600.1106\src\print\oemdll\oemps". 4.. Typed "build -cef". Command.cpp failed to compile because KeQuerySystemTime and RtlRandom were 'undeclared identifiers'. Because these two api's are defined in ntddk.h, I added '#include <ntddk.h>' to command.cpp. The compile failed because it could not find ntddk.h. I then changed the line to '#include < C:\DDK\WINDDK\2600.1106\inc\ddk\wxp\ntddk.h>'. The compile failed again because I had several redefinition errors. How do I get api's defined in NTDDK.H to compile in this (oemps) Microsoft provided sample project? Tag: Access USB device from userland Tag: 40908

 - Unidrv: Custom Halftoning on Windows NT Since The *HTCallbackID does not work on Windows NT, we have hooked the IPrintOEMUni::ImageProcessing() callback to apply the custom halftone pattern This Unidrv based PCL driver is for a monochrome printer. The values in our custom halftone pattern are in the range of 0 to 255. Hence to apply this pattern we have the following values in the ColorMode feature of our GP *Feature: ColorMod *rcNameID: =COLOR_PRINTING_MODE_DISPLA *DefaultOption: Mon *Option: Mon *rcNameID: =MONO_DISPLA *Color?: FALS *DevBPP: *DevNumOfPlanes: *DrvBPP: *IPCallbackID: 334 We *have* to convert the source DIB to 1BPP and give it back to the UNIDRV after ImageProcessing() returns. The indexes in the pSrcBitmap to the pColorTable where converted to grayscale values using the formul greyvalue = rgbRed * 0.299 + rgbGreen * 0.587 + rgbBlue * 0.114 We tried dithering the 8BPP grayscale DIB using Flyod-Stienberg algorithm, but are not able to reproduce the same quality DIB the UNIDRV gives us when the *DrvBPP is Are we missing something How does GDI do the dithering from 8BPP to 1 BPP Is it possible to dither 8BPP greyscale to 1BPP Monochrome image of the same quality as GDI's dithering Tag: Access USB device from userland Tag: 40899

 - Question about using IoGetDeviceObjectPointer() in Win98 Hi, All, I develop a WDM Driver that in the AddDevice()£¬I use IoRegisterPlugPlayNotification() to register listen to an USB device's insert/remove.In its callback function, I use following code to get the DeviceObject£º if(IsEqualGUID(dicn->Event, GUID_DEVICE_INTERFACE_ARRIVAL)) { status = IoGetDeviceObjectPointer( dicn->SymbolicLinkName, FILE_ALL_ACCESS, &pFile, &pdo); ................. } I found that in win 2000£¬the pdo return back is tha same as the DeviceObject of the lower driver. So after that, the IRP build by me can be successfully send to the lower device¡£At this time, the dicn->SymbolicLinkName looks like \??\USB#Vid_6513Pid_0089#51e37dc9701#{guid} But in win98, the same codeget different result. IoGetDeviceObjectPointer £¨£©return NTSUCCESS£¬but the pdo return back is different from the DeviceObject of the lower driver. The IRP build by me£¬can't be send to lower driver by IoCallDriver()¡£what's the problem? this time £¬the dicn->SymbolicLinkName looks like \DosDevice\0000000000000002\{guid} Further more, I found that, in win 2000, when I call IoGetDeviceObjectPointer(), the lower driver will recieve an IRP_MJ_CREATE. But in win 98, the lower one can't recieve that IRP. why? It seems so strange. in win98, the IoGetDeviceObjectPointer() can return success, and give a pdo to me, but I can't use it. Could anybody be kind enough to show me some light in that? Thanks in advance! Tag: Access USB device from userland Tag: 40894

 - Need Help on POSUSB Hi , I am implementing a Virtual Com port driver for our Target Device on WinXp. For this, I have taken the reference driver code from Microsoft POSUSB The issue is that while doing an install / Uninstall or Enable / Disable of the Virtual Com Port, the OS asks for a system restart. I am interested in knowing if this is an acceptable behavior as we are planning to do HCT validation of the driver. We have referred to the HCT documentation for the same, but in no place does it say that this restart is acceptable. Unfortunately, I have not been able to find how serial port emulation can be done without the above said behavior. when i Disable/Enable or Install/Uninstall the device, i am not handling the RemovalRelations in the IRP_MN_QUERY_REMOVE_DEVICE.i am just passing that IRP down as STATUS_SUCCESS. after that i am geting IRP_MN_CANCEL_REMOVE_DEVICE this is because of bus driver not process it proper. But as per Documentation you need not worry about this IRP. I would be very grateful if you can guide me in this regards. thanks in advance Regards, Deepak.

 - Writing storage device driver for a flash PCI card Hello, I have a PCI adapter that has flash memory on it. I know everythings about this card, including the PCI manuf device ID, the PCI config register, and how to read and write from/to the flash memory. I want to write a driver for it such that when I open windows explorer I will see my card shown as drive D: (or E: if there is a CD rom in the system). I have been reading books, including Programming the MS WDM 2nd, Oney, and the DDK documentation from the lastest DDK for Window 2000/XP. Too much information has made me confused. 1. Should I write the SCSI mimiport driver that will layer below the scsi port driver? I read about this SCSI miniport things but it's really confused. I have thought about this but when I look at the functions that I have to implement shown in the DDK, it is too complicated. My PCI card does not use DMA and IRQ. It only need two 32-bit registers and a 4k memory range and an IO port that is part of the PCI config space. 2. What are the alternatives? Port driver? I thought my driver must be a port driver, since it must tell the system how to read and write to the PCI register. But it must contain a layer that tell the system that my drive is a D: drive. Anyhow, this whole thing is a mess in me right now. Can someone explain or show me what the best approach to this? Thank you so very much. Long Tag: Access USB device from userland Tag: 40880

 - Keyboard mouse stream separation - again... Hello folks, again I am having a few questions belonging to my previous topics. I want to separate keyboard and mouse streams originating from different devices - Windows shall only get the information of one device combo. The others shall be used for whatever. I have written adopted DDK filter driver examples for PS/2 chain. This works but is a bit dirty. The DDK also contains the original "keyboard class" and "mouse class" drivers. Wouldn´t it be possible to adopt them to deliver this feature? How are those driver examples installed? DDK help says that they are protected by system driver protection... How can you prevent XP from caring about those drivers? Many thanks for your help... Volker Tag: Access USB device from userland Tag: 40878

The service entry for the driver in the registry shows that INITSTARTFAILED is 1. The same device can be reconnected fine in Windows XP Professional SP1. I use the same version of sbp2port.sys (5.1.2600.1106) in both cases. Any advices what and where to change in WinPE configuration? Thank you. SD. Tag: Access USB device from userland Tag: 40866

 - Share memory between user mode and kernel mode Hi A windows application (user mode) create a memory area with CreateFileMapping(INVALID_HANDLE_VALUE, NULL, PAGE_READWRITE,0,TAILLE_BUFFER,"SharingImage" I want to use this area in a driver (kernel mode). According to the Microsoft knowledge Base 191840. I have to use the following functions - ZwOpenSection( -ZwMapViewOfSection( But I don't know how to get adress of the area The source is RtlInitUnicodeString(&ShareMemoryName,L"\\SharingImage") InitializeObjectAttributes( &InitializedAttributes, &ShareMemoryName, OBJ_PERMANENT | OBJ_CASE_INSENSITIVE, NULL, NULL) status = ZwOpenSection( &pat_AcquisitionFile,SECTION_MAP_READ, &InitializedAttributes) the return code is always "STATUS_OBJECT_NAME_NOT_FOUND" What can I do to point to the right are Thanks Pasca Tag: Access USB device from userland Tag: 40854

 - Win98 unidriver/landscape mode banding Is there anyway to get a vertical banded RGB data in Win98 unidriver ? I set sPlanes=1, sBitsPerPixel=24, thus a fnOEMDump() function is required. Unidriver bands portait pages in printing direction, that's fine. Problem raises when i print with landscape mode: If i set MD_LANDSCAPE_GRX_ABLE in fGeneral, it will band landscape page horizontally, which is not the printing direction. If i clear MD_LANDSCAPE_GRX_ABLE in fGeneral, UniControl() returns the whole page dimension at 1st time NEXTBAND was called, and returns empty rect at 2nd time NEXTBAND was called. This is absolutely not what we want. We'd like to have correct band rect(s) for landscape mode. Is there any solution for such condition in unidriver ? Or the only way is to write my own driver ? Thanks in advance. Tag: Access USB device from userland Tag: 40853

 - firewire delayed write failure Hi everybody, i have a problem with an external firewire hard disk. The problem is a "Delayed Write Failure" when i try to read some kind of file (DV AVI most of the time). The root cause of the problem is explained at http://www.bustrace.com/products/delayedwrite.htm. On this page there is also a little test tool that is able to reproduce the problem. The solution is to write a filter driver that prevents IO larger than 128Kb to reach the drive. Is there anyone able to write a filter driver like the one described in the link and post it to the community? thank you. Tag: Access USB device from userland Tag: 40851

 - 1MHz interrupt Hello, I would like to write an application that would periodically write bytes to the parallel port with frequency ranging from several Hz to 1MHz. I thought I could use the hadrware timer to genearte interrupt every time and write a device driver to handle it. However, my first question is: Is it possible to accomplish it? I mean, is it possible to get such a high frequency reliable under Windows? will not my interrupts be delayed by task switching, other interrupts etc. Is it possible to disable task switching etc for a short time? Or would it be realiable at least in the case that no other applications run Thank you very muc Tag: Access USB device from userland Tag: 40844

 - SPTI rejects valid requests I'm witing some low level CD access stuff (writing DAO in RAW mode and things). I'm mainly using SPTI, cos I'm developing under XP. The problem I'm having is that a number of calls are failing for no apparent reason. These calls work perfectly when I use ASPI as the transport (I choose to use ASPI or SPTI when my base level object is initialised - all the CDB construction and so on are in higher levels and identical). The 2 calls which I'm seeing give problems are Read TOC (ATIP) and ReadCD (with a -ve LBA). I've looked at the CDB and in both cases it is identical. The errors I'm seeing are Address out of Range (for Read CD) and 'invalid Operation for this track' for the ATIP reading. I cannot believe that something in Windows is doing this. But on the other hand, nor can I see anyting odd I'm doing with these particular functions. The Object proper is quite happy to use dozens of other functions (including ReadToc with other parameters!) and happily writes audio cds and DVDs and reads the same. Just these few functions ... Can ayone throw light on this? Iain Tag: Access USB device from userland Tag: 40839

 - Map interface index from the IP Helper API to an intermediate driver miniport instance. Hi! Is there any way for an intermediate driver to find out (in either ProtocolBindAdapter or MiniportInitialize) what interface index (IP Helper API) it will get. In userspace I keep track of adapter by their iphlp index and I would like to make a call down an intermediate driver with that index instead of the name of the adapter. It would be awesome if each of my miniports instances could figure out that index on their own. Cheers! Tag: Access USB device from userland Tag: 40836

 - ISR not called Iam writing a device driver for PCI card Iam using a interrupt. I have initialized the interrupt and connected the InterruptServiceRoutine by the call IoConnectInterrupt.Also the DPC object is initialized for the DpcForIsr routine by IoInitializeDpcRequest. In the interrupt service routine First checked for the interrupt whether it is from my card if it is not returned FALSE immediately. If it is from my card then acknoledged it. Then some processing is done. Then the DPC object is queued to continue the request processing by IoRequestDpc. Return TRUE from the Interrupt Service routine. When I debugged the program ISR routine is not called. Am I doing any mistake. Secondly when I restart the system, the system was hung.I think the problem is due to not disabling the interrupts in correct way.What am I supposed to do.

 - UPS minidriver Dll Hi I'm currently developing a UPS minidriver Dll for Windows XP The UPSTurnOff function has a parameter DWORD aTurnOffDelay The DDK describes the parameter as Specifies the minimum amount of time, in milliseconds, to wait before turning off the UPS unit's power outlets. Called by the UPS service, I get here 180 Does this mean that I have to wait 180ms before issueing the output to the UPS to shut down Does this mean that I have to issue the output 180ms long It CANNOT mean that the UPS has to turn off 180ms after issuing the output because XP has no even begun to shut down I assume this value is in seconds. 180s seems to be an appropriate value for shutting down XP Thanks for your help Tag: Access USB device from userland Tag: 40819

 - How can I lock user memory at DISPATCH_LEVEL? Hi My driver has to do lots of Scatter Gather List DMA operations. This used to be ok at PASSIVE_LEVEL, but it becomes a problem when I try to use a system queue and call DMA operation in my StartIo routine. Before I can start DMA operation, I need call IoAllocateMdl() to build MDL for the user memory and call MmProbeAndLockPaged() to lock the user memory into the physical pages. According to DDK document, MmProbeAndLockPages() function can be called at DISPATCH_LEVEL ONLY when the memory is not pagable, but I have no way to guarranttee that the user memory is nonpagable, right Is there anyway I can get around this Thanks zhong Tag: Access USB device from userland Tag: 40799

Hi,

I'm trying to write a application that is able to send vendor unique reqeust
to our USB device. I tried USBView in DDK, but it doesn't work on my XP box.
It always fails in IOCTL_USB_GET_NODE_CONNECTION_INFORMATION_EX.

Is there any documentation related with USB userland app? The DDK
documentation is all about writing a driver, which I'm trying to avoid here.

Thanks,

Zhen

See CreateFile(), DeviceIoControl(), CloseHandle (also see ReadFile() and
WriteFile() ).

Three excellent books on USB are:
* "USB Complete" Jan Axelson, Lakeview Research, http://www.lvr.com
* "USB Design by Example", John Hyde, Intel Press
* "Universal Serial Bus System Architecture", Don Anderson, MindShare

The first two are excellent general USB references with lots of good
implementation examples. Be sure and check out Jan's web site, there's lots
of good info there. The third is an excellent detailed reference on how USB
works but is very thin on implementation examples.

*THE* book on writing WDM drivers is, "Programming the Windows Driver
Model", Second Edition, Oney, Microsoft Press.
