    - Problem! Either memory or IO locations are accessed in Win2K WDM driver Hi All, We written a WDM driver for 16 bit PCMCIA PC card in Win2k.We are able to read only either Memory or IO locations.We defined one IO resource,one INTR and Two Memory ( attribute and common) resources in INF file using LogConfigOverride section as shown below. PCCARD.NT.LogConfigOverride] LogConfig = Override0 [Override0] ConfigPriority = NORMAL IOConfig = 21@300-3FF%FDF ; IRQConfig = 3,4,5,7,9,10,11,12,15 ; IRQ MemConfig = 1000@0-FFFFFFFF%FFFFF000 ; Attribute Memory Descriptor MemConfig = 4000@0-FFFFFFFF%FFFFC000 ; Common Memory Descriptor PCCardConfig = 1:0:0(AC M XM0) ; ConfigIndex In device manager our device properties window If I use automatic settings, we are able to read/write Attribute and Common Memory. We are not able to access IO locations. And if I uncheck the "Use Automatic settings" , and select one of the IO resource from the "Settings base on" combo box which is not conflicted IO resource. In our case it ranges from 0x200 to 0x221. In CIS tuples I defined 0x200 as IO base and 0x21 as IO Range.If I set this only resource as current configuration. Then We are able to read/write IO locations. Since this manually selected Current configuration, there is no memory resource that's why memory is not accessible. In order to get the access to both memory and IO What should I do? Any mistake in INF file please correct me. Thanks in Advance. Mahender. Tag: writing on Base Address Registers Tag: 72415

    - UniDriver Printer Driver with Plugins, adding device(custom) fonts at run-time via OEMQueryFont UniDriver Printer Driver with Plugins, adding device(custom) fonts at run-time via OEMQueryFont Basically, I need to be able to add "device fonts" at run-time WITHOUT having to specify the fonts in the GPD file. I can install device fonts at run-time, but am limited by the "DeviceFont" entry in the GPD file which is fixed upon printer driver installation. More details follow: I need to be able to add "fonts" via OEMQueryFont(-) at run-time (via "Printer Properties"); the fonts are constructed at "run-time" by user input. I cannot (do not want to) list all possible variations of the fonts in the GPD file or likewise specify "font files" for all of these variations. (Please note that the "monolithic" version of the printer driver functioned correctly.) The test to see whether a "device font" is installed is to go to MS Word and see the device font entry in the "Font" drop-down list. As for adding device fonts, apparently, OEMQueryFont(-) is called ONLY when there is an entry in the GPD file for device fonts (i.e. " *DeviceFonts: LIST(1,2) "). Furthermore, the function is called once for each entry in the list (i.e. in this case, once for "1", then for "2"). If only 2 device fonts are "created" at run-time, then everything works OK. However, if more than 2 device fonts are "created" at run-time, then NO device fonts appear to be installed (i.e. not seen in MS Word "Font" drop-down list. Any ideas? Thanks, Rudy Tag: writing on Base Address Registers Tag: 72408

    - More Printer driver debugging More confusion in debugging printer driver :( I am debugging the MSPLOT sample driver by placing OutputDebugString on the main exported functions to see which of these are being called, on adding the driver by the add printer wizard. Using WinDbg I am receving some output from DllMain and DrvQueryDriver but after that all output stop (not because these are the only functions called, it has to build the propertysheets so wheres the output from those functions), even if I output to a trace file. Whats strange is that I am recieving some error msgs from DrvDeviceCapabilities but without recieving the debug str that i wrote to inform me that it entered the function. I think it could be because 1. The driver fell to Kernel Mode at somepoint 2. The driver created some other process outside the spooler and all msgs are falling 3. The spooler process doesnÂ´t give me the rights to see the messages or doesnÂ´t allow the driver to send messages or write to files! What do you people think?

    - Symantec Ghost 10.0 on XP SP2 w/WinDbg In the past I've used DriveImage and later Symantec Ghost to image disks on machines used for debugging particularly invasive, or particularly unstable driver projects. Setting up a new Dell PowerEdge 1800 dual Xeon box, I installed XP SP2 and connected it via a serial cable to another box running Windows Server 2003 (which I don't think is relevant but I've been wrong before). The basic setup worked as expected. However, attempting to use the latest Ghost 10.0 from Symantec was no picnic and I'm wondering if anyone here can explain the problems that I'm seeing. Install attempt #1: As a matter of course, I typically always boot the target box with all debugging options enabled in the boot.ini file and connect to it with WinDbg regardless of if I'm debugging a driver project or not. So I thought nothing of running the Ghost 10.0 installer on this setup. However, this generated first-chance exceptions that halted execution landing me at the WinDbg command prompt. Although somewhat atypical for production code, I thought nothing of it and figured that the exception would be handled. Possibly it was. But the Ghost installer reported "setup was interrupted - no files or settings have been modified". Well that's not true at all but it's off topic. Install attempt #2: Rebooted without the debugger, installed Ghost w/o obvious error and performed an initial backup of the test target's single SATA drive. Maybe this was just some installation problem? I tried rebooting back into the debugger with Ghost installed only to be hammered with exceptions in WinDbg. According to the Symantec support pages Symantec products aren't compatible with kernel-mode debuggers. The following two articles on the Symantec website provide an insufficient amount of detail to be of any use whatsoever. Kernel debuggers and debug output viewers are incompatible with Symantec programs http://tinyurl.com/ddoor Compatibility with kernel debugger programs http://tinyurl.com/dlyfj What's the conventional wisdom these days for imaging disks on hosts that (a) must be run routinely under WinDbg (b) are likely to suffer such abuse that they become unbootable and require restore from backup image in order to efficiently re-esablish the controls required for valid testing of kernel drivers? sysresccd.org sure looks nice but it doesn't seem to support SATA drives yet. Anyone have a suggestion for getting Ghost working, a way to use sysresccd on a SATA drive, or suggestion for another utility? - Thanks in advance and regards Chris Tag: writing on Base Address Registers Tag: 72393

    - usbvideo.sys verbose output? I'm having trouble getting any debug output from the usbvideo.sys driver. I have a Windows XP SP2 machine, with a partially checked build installed (usbvideo.sys and usbport.sys are checked builds). It is connected via firewire to another XP machine. WinDbg connects in kernel mode. I do not get much in the way of debug output. What's the next step to get verbose output? I'm developing a USB Video Class compliant device. Thanks!

    - Autoplay Radio device? I am trying to build an USB FM receiver. The USB device have a preset frequency programmed into the microcontroller. My ultimate goal is to have the device plug in and start playing the radio station PC with no drivers or software installation. I am stumped on the best way. I have considered a mass storage device with player software in the flash memory. Is there a better way? I would think Audio Class would be good. Can a Audio device automatically send data to the sound card (or speakers) with out special drivers or software? Thanks much! Tag: writing on Base Address Registers Tag: 72383

    - Problem on 64 bit processor I have ndis IM driver - tested on w2k+sp4,w2k3+sp1,wxp+sp2 on 32 processors. All is ok. When I install this driver on w2k+sp4 on 64 bit processor (Intel EM64T) driver crashes, no blue screen appears and system restarts without blue screen. Question: When I want to use ndis IM driver on 32 windows systems installed on 64 bit processors - do I need to add some defines, or does need my driver code some adjustments for running on 64 bit processor ?

    - Loading a driver from a mapped drive fails The call StartService() fails when the driver is located in a shared network drive or have a network drive mapped to a drive letter. As an example, the DDK's sample exe for CANCEL and EVENT have this issue. I can run them OK within my local drive, but when I place them in a network shared drive (mapped to Z: drive), the call to StartService() returns ERROR_PATH_NOT_FOUND. I called QueryServiceStatusEx() and ControlService() with SERVICE_CONTROL_INTERROGATE, and dwCurrentState always shows ADS_SERVICE_STOPPED and not ADS_SERVICE_START_PENDING. Can anyone help?

    - Debugging IRQL_NOT_LESS_OR_EQUAL Hello, I have a driver than runs on ksproxy for my hardware device. The driver works but I have intermittent issues on enable/disable of the driver which will generate the IRQL_NOT_LESS_OR_EQUAL exception and kill the machine. The driver was made with DriverStudio's tool derived from their KsDevice. I'm trying to track down whether it's something I've done (with bad use of spin locks perhaps) or if it's something in the DriverStudio framework. Has anyone had similar issues or have some suggestions for tools/techniques to nail down the issue. I'm using SoftIce as my debugger right now but the error doesn't happen in my functions, that I've been able to trap. It seems to happen (at least on enabling the driver) after I receive an IRP_MN_QUERY_DEVICE_RELATIONS which I don't handle directly. Thanks for any help!

    - DDK EULA / using sample source in commercial projects Hi-- My employer has a DDK license. I'm not sure of the exact licensing details (e.g. which flavor if there are indeed flavors). We would like to include some code from the DDK in a utility we are developing. The project in the DDK is called DevCon. So: We'd like to include/use some source from DevCon for an installer we are writing. We don't want to actually use the DevCon utility executable. We just want to use some of the source code from the utility which will be compiled into a new utility that does other things beyond what DevCon does at the moment. But it is a commercial project and could be going on potentially tens of thousands of CDs. Can someone categorically say 'Yes, you can use code from the DevCon project for your own utility. Don't be stupid, that's what its there for.' Or can someone say 'No, you can't use code from DevCon in your own project because its not redistributable, can't you read?.' Or can someone point me in the direction of a more developer-friendly FAQ or some other resource that won't require a lawyer to understand (the EULA below is just plain confusing)? Or, if its a gray area, can someone tell me which department at Microsoft to contact? In the EULA it says: "You may also reproduce and distribute the Sample Code in object code form along with any modifications you make to the Sample Code, provided you comply with the Distribution Requirements described below." There is no section in the EULA titled 'Distribution Requirements', but there is a section called 'Redistribution Requirements'. In the redistribution requirements it says (amongst other things not applicable to a utility): "Contact Microsoft for the applicable royalties due and other licensing terms for all other uses and/or distribution of the Sample Code." Further, there is text on the page describing DevCon (http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q311272) which says: "DevCon is not redistributable. It is provided for use as a debugging and development tool. You can freely modify DevCon for *private* (my emphasis) use. The sample demonstrates how to use the SetupAPI and CfgMgr32 functions together effectively to enumerate devices and perform device operations." I'm not a a lawyer. And the EULA that comes with the DDK seems to be confusing if not inconsistent when viewed in light of other text that governs individual utilities included on the DDK. The EULA is below.

    - step in-between printer (LPT) I need to develop some software that will step in between a computer and it's printer. The software should read from one LPT port (connected to printing computer) and then redirect that traffic out a second LPT port (connected to printer). It will do stuff to the data as it goes by. Can you give me any direction on what is needed to develop this? How do I read/write to/from the LPT port in Windows? Are there any libraries available that can manage the communications? Do I need to develop a driver to do this? Thanks! Tag: writing on Base Address Registers Tag: 72324

    - USB selective suspend freeze Hello I'm writing usb function drivers. The usb device is a composite device with 4 interfaces. The device supports remote wake-up. 1 driver services 1 interface, another the 3 other interfaces. I'm running on WinXP SP 2. When the device is idle for 3 seconds, the drivers send down a idle request on each interface. After that, the callback routine of the idle request is called for each device. Each device sends down a wait wake irp and transitions to device power state D2. At this point, I can surprise-remove the device, I can disable the composite driver (to imitate safe removal), I can go to standby, I can hibernate, but I can't shut the system down. When the system goes to S5, something hangs in the USBD. I've tried to cancel the idle request in the power dispatch routine for "Set S5", but the IoCancelIrp() never returns. I've tried not to cancel, but then the usbd gets stuck when I abort a bulk out pipe. When I shut down without the device in selective suspend mode, everything is okay. What am I doing wrong ?

    - multicast Will ping to multicast address work in Windows at all? Eg: ping 224.0.0.1 Will this fetch responses from hosts already joined to this group and in the same subnet. Though I see that I receive this multicast packet on my stack, there is a time out to this ping in the command prompt. thanks Tag: writing on Base Address Registers Tag: 72305

    - Printer driver install Hi there, I have build a small monolithic printer driver prototype for win2003 x86 and I am trying to install the driver via the add printer wizard but it is not installing and I am recieving a "Printer driver was not installed. Operation could not be completed" (not much info :(). Now I am trying to attach windbg to the spool process to see what is happening but windbg is not loading the symbol files and not recieving any of my debugging messages from the driver. I think that the driver is not being started at all, but then what could be causing error? I am stumpped, is there any body out there that can help me; what functions are loaded first by the spooler when installing and what could be the causes of such malfunction. Thanks in advance Tag: writing on Base Address Registers Tag: 72304

    - =?iso-8859-1?q?NdisIMInitializeDeviceInstance=ADEx_Not_Returning_(dead_lock)?= Hi, I have an IM driver that worked well untill now. I encounter a problem on 2-processors machine (windows 2003 sp 1) with 2 NICs teamed together with compaq teaming driver (cpqteam.sys). The problem is that when issuing "ipconfig /all", the IP configuration is empty. During debugging the OS startup, I noticed that my driver is waiting for the cpqteam to finish it's binding to specified NIC (inside NdisIMInitializeDeviceInstance=ADEx function), and that cpqteam driver is waiting to my driver to finish it's binding to the same NIC (again, inside NdisIMInitializeDeviceInstance=ADEx ). That is a dead lock. After waiting for a while, the 2 threads are killed and the binding process is failed. More info: In my driver, the MiniportInitalize function is called returns successfully. Any help whould be appreciated. Thanks, Ran. Tag: writing on Base Address Registers Tag: 72302

    - Keyboard filter driver - obtaining keyboard indicator status Hi all, I am new to device driver development and am currently writing an upper filter driver for a USB keyboard. My first step I am trying is to obtain the LED information from the keyboard from a user-mode application. I have followed the Windows example (toaster filter) regarding creating a control device object in the upper filter driver and am able to obtain a handle to this control device object in the user-mode application. However, I then attempt to obtain the LED information as follows in the application: USBHandle = CreateFile("\\\\.\\KeyboardUSB", GENERIC_READ | GENERIC_WRITE, NULL, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL); if (USBHandle != INVALID_HANDLE_VALUE) { status = DeviceIoControl(USBHandle, IOCTL_KEYBOARD_QUERY_INDICATORS, NULL, 0, &kbdParam, sizeof(kbdParam), &outLength, NULL); } In the filter driver, I receive the correct IRP (as below in my DispatchIO routine), but am unsure how to obtain and return the correct data. Below shows what I am currently attempting to do. irpStack = IoGetCurrentIrpStackLocation(Irp); switch (irpStack->MajorFunction) { case IRP_MJ_DEVICE_CONTROL: #ifdef DEBUG WriteLogFile("DispatchIo: IRP_MJ_DEVICE_CONTROL\r\n", 35); #endif switch (irpStack->Parameters.DeviceIoControl.IoControlCode) { case IOCTL_KEYBOARD_QUERY_INDICATORS: #ifdef DEBUG WriteLogFile("DispatchIo: IOCTL_KEYBOARD_QUERY_INDICATORS\r\n", 45); #endif return FilterPass(MainDeviceObject, Irp); break; default: break; } default: break; } Therefore, my main question is how to execute the IRPs correctly that are created from my application using DeviceIoControl. Do I need to use completion routines and if so, how should these be used? Thanks in advance, Kyzer Tag: writing on Base Address Registers Tag: 72294

    - USB client driver between Usbhub.sys and other client drivers. Greetings Experts! I hope some of you were written USB Client drivers for XP and 2000. I have to do the same - an USB client driver on top of Usbhub.sys. The only purpose of this driver is to implement vendor-specific request IOCTRL_ and talk to the Enpoint 0 of an USB device. The problem here is that in our system there are some other USB Client drivers like usbser.sys, blan.sys, some composite client drivers, etc. The driver I am to write should expose an additional interface in the Device Manager and co-exist with these client drivers. In my opinion I should place my 'vendor-specific' driver on top of Usbhub.sys and below another USB client drivers that we have. Please correct me if I am wrong. It seams that the problem here is how to place this driver properly in the driver stack... I will be very grateful if you can give me information, an advice or direct me to some DDK samples implementing a similar driver. Thanks in advance!

    - How to load NDIS driver for SDIO bus in Windows CE? I hope some one can help. I am trying to write a NDIS driver in windows CE. The driver interface is an SDIO bus. My first step was to write an SDIO stream driver to test that card. It's worked like magic. Second step was to try loading an NDIS driver for this card. According to Microsoft documentation I have to do the fallowing: 1. Write a dll that export "DriverEntry". 2. Add a key in the registry [HKEY_LOCAL_MACHINE \Comm \MYDRV] DisplayName="MYDRV NDIS Driver" Group ="NDIS" ImagePath="MYDRV.DLL" [Linkage] Route="MYDRV1" [HKEY_LOCAL_MACHINE \Comm \MYDRV1] DisplayName="MYDRV NDIS Driver" Group ="NDIS" ImagePath="MYDRV.DLL" [Parms] BusNumber=0 BusType=0 [HKEY_LOCAL_MACHINE\Drivers\SDCARD\ClientDrivers\Custom\MANF-02DF-CARDID-9103-FUNC-1] DLL="NDIS.DLL" Prefix= "NDS" Miniport=" MYDRV " As a resulted my DllMain was call twice one for load and one for unload. Can some one tell me what I am doing wrong? Tag: writing on Base Address Registers Tag: 72286

    - WinCE crash - HeapAlloc function Hi, I am working on a passthru driver for WinCE platform and recently (after updating the wlan.dll as there was some problem with the adhoc mode), it started crashing randomly. Some of the crashes are outside the modified passthru driver. I have attached few crash dumps below. I am not having any clue for the crash as it is happening randomly, sometimes after running the system for few minutes and sometimes after few hours. Any insight in this problem will be greatly appreciated or how can I go about debugging this problem. Thanks, -Niranjan Wireless Terminals Lab, Samsung Telecommunication America.

    - Bug check calling nt!RtlQueryEnvironmentVariable_U Hello, I am writing a minifilter driver that reads some configuration data from the registry in its DriverEntry procedure using RtlQueryRegistryValues. If I use REG_SZ values in the registry then everything works as expected. However if I use REG_EXPAND_SZ values the system bug checks when calling nt!RtlQueryEnvironmentVariable_U. The bug check is PAGE_FAULT_IN_NONPAGED_AREA (50) and it occurs right at the beginning of RtlQueryEnvironmentVariable_U. When I examine RtlQueryEnvironmentVariable_U in the debugger it looks like the procedure is paged out (the debugger just shows ?? for the diassembly). Details are at the end of the message. Can anyone tell me what's going on and how to fix the problem? I'm using the Windows XP SP2 checked build with the driver verifier enabled for my driver (same problem occurs with the free build without the driver verifier IIRC).

    - A question about gdi functions for a print processor. Hi I'm working on a printer driver. ours is Unidriver-based driver. I'm programming with the sample sources of a print processor that are in the Windows DDK. (\WINDDK\3790\src\print\genprint) The sample sources already implemented a few printing features such as n-up, reverse printing, etc... i want to make a feature of manual duplex with the sample sources, but i got a problem. As you know, the manual duplex feature is that the front data of pages for duplex is printed at first, and then the driver show a message box that inform of the user to put the printed matters on the multi-purpose tray. Finally, the back data of pages for duplex is printed. So, i refered to the sample code amd made a linked list that store a page information. i used Gdi functions for a print processor such as GdiStartDocEMF() and GdiEndDocEMF().... but.. I got a problem.. the problme is that after the front data of pages for duplex is sent to spooler, i called GdiEndDocEMF() function to eject all the front data of page from printer. At that time, unforunately.. the emf data is deleted from spooler. T_T although i called GdiStartDocEMF() to tranlate the back data of pages, the return of the function is failed,(the GetLastErr() is 62).. what function do the GdiEndDocEMF() replace to eject all data from printer? how can i implement the maunal duplex feature in a print processor?? if you know, plz... let me know how to do or what to do.... thanks. wany.

    - How to open this transport address Hi, I have tried to open raw ip in kernel mode "\device\rawip\255" or "\device\rawip\17" (UDP) or "\device\rawip\1" (ICMP), all is OK, I can to use it for sending packets. Problem is that I need to open raw ip for TCP. When I am trying to open transport address with device name for TCP: "\device\rawip\6" ZwCreateFile() returns 0xC000000D. I am trying it with the same way like for above successful attempts, I pass only different device name. What is different in opening address for TCP ? Must be set some different object attributes or something other ? Peter Tag: writing on Base Address Registers Tag: 72253

    - getting serial.sys to work for an ISA based 4xserial port card to work I have an ISA based card with 4 serial standard serial ports(16550 type) that share an IRQ (using a cpld) that I would like to use with windows 2K. As far as I can understand it, i can use the driver included with windows (serial.sys) and I need to write a wrapper of some kind and an INF file. Is this a correct assumption ? Are there any links to information that more or less outline the steps to do something like this ? (as i have no prior experience with developing kernel mode drivers on microsoft platforms.) I would just like to estimate the difficulty of this job first, it seems to me that it should be fairly simple. Thanks very much, Tag: writing on Base Address Registers Tag: 72250

    - Page limit when using GDI to print Although this is a client side issue, I believe the real issue is a buffering limit in the printer driver. Since our Unidrv-based printer driver is the first driver Iâ??ve ever worked on, I am curious if I am diagnosing this problem correctly and if I understand all possible solutions. We are experiencing a page limit when using GDI printing. After printing 85 pages from our application, we get a failure. We raised our Unidrv-based printer memory limit to 2 GByte maximum and printing fails consistently on the 86th page. This happens whether we print to an external printer or to our Unidrv-based software PDF printer, i.e. a printer that creates a PDF document. When we print from our application using GDI printing, the return value for the EndPage function for the 86th page is 0cFFFFFFFF, i.e. -1, and GetLastError returns 0 (zero). We then call AbortDoc. If I modify the code to allow printing to continue, only the first 85 pages are printed. The same thing happens on an external printer. Note, we do not believe that any pages approach the 350 MByte limitation mentioned in the documentation. Also, if we delete pages at the beginning of the document, then the document will still print only 85 pages, i.e. some pages that previously didnâ??t print suddenly print. Is the only solution to reduce the color-depth the 24 bit color images ouor application produces, and of course, greatly reduce the size of the images for gray scale or black and white printing? Then Ican modify the device context to reduce the memory requirements for each page. Is there anything else I can do? If that is the solution, do printers typically use 16 bit color, 8 bit color, or something else? We do need to be able to print photographs to high quality printers, but the buik what our application deals with is black and white documents. If those documents contain a color photograph we do want to support printing that without such a small page limit. We've heard of customer documents that exceeded 4000 pages! (Granted, these are quite rare, but 1000 pages is no unheard of). Thanks in advance. P.S. Our printer driver is a Unidrv-based PDF printer driver, i.e. it produces PDF files. It was built using DDK 3790. We support Windows 2000 and Windows XP. It was developed using the Unidrv sample code provided in the DDK. The printer-generated PDF file is sent to an application we also have developed, i.e. there is no hardware printer. ------------------------------------------------------------------------- I posted the message above in the win32.programmer.gdi newsgroup in a post titled "Page limit when using GDI printing.", and I received the reply below from Rhett Gong [MSFT]: Note however, despite his reply, that this is NOT just a Unidrv issue. It happens when using GDI to print to other printers. I responded in that forum, and included the calculation that shows that 2 GBytes will handle 85 8.5 inch by 11 inch 300 DPI 24 bit color images. (2 to the power 31) / ( (300 DPI * 8.5 I) * ( 300 DPI * 11.0 I) * 24 bits/pixel) ) = 85.0 This is what makes me believe the page limit is related to buffering in the driver (or at least buffering somewhere). The issue is that printing doesn't start until EndDoc() is called. Is it reasonable to raise the driver buffering way above the virtual memory limit? Is this data all mapped to a file? I do not want to segement a 1000 page print job into multiple jobs as these arrive back asynchronously from the Unidrv printer and are loaded into our application. Having to append these over and over again would annoy most users. Note also, there are two separate issues. 1. GDI to other printers. 2. GDI to our Unidrv-based printer. A solution to either of these would be useful. Is this a fundamental limitation of GDI printing? (An answer to that would help me to stop pursuing something with no solution). ------------------------------------------------------------------------- Hello From your description, you write a Unidrv by yourself, but you can only print 86 pages and then EndPage return -1 and not further error code returned . Based on my understanding, this is a Printer Driver issue and require debugging into the printer driver to find out the problem, so I would suggest you post this question to following newsgroup: microsoft.public.development.device.drivers It is a managed newsgroup. and all DDK issues and driver dev questions are posted in the newsgroup above.

    - Synchronizing Timers and ISR I am attempting to synchronize Timer procedures with the ISR. When my timer expires it should perform operation A. If the ISR runs prior to that it will perform operation B and cancel the timer. What I am concerned about is the possiblity that the timer will expire, start executing, and get interrupted prior to reaching the Critical Section. In this scenario, Operation B will be performed by the ISR followed by Operation A by the timer. Is there a method to prevent this from happening? Thank you.

    - Correct DDK Windows 2000 SP4 I have Visual Studio 6, my O.S. is Windows 2000 SP4. According to the MSDN order site the correct DDK for my system is the Windows Server 2003 SP1 DDK, which I ordered. My main interest in the DDK was to obtain the Usbview,c source code, however Usbview.c will not compile on my system, it generates errors. I have been told by a systems developer that I need the 'Windows 2000 DDK' in order to compile Usbview.c on my system. The 'Windows 2000 DDK' is now only available to MSDN subscribers and I am not yet an MSDN subscriber. If the above infromation is correct, can anyone here on the forum who has the Windows 2000 DDK post back with the year(s) and month(s) of the MSDN subscription CD that included the DDK.

    - Problems performing USB Isochronous/Bulk Read/Writes and unplugging device Hello all, hello Mr. Roberts! After clearing some general misunderstandings, maybe you could help me once more with the second part of my former post. I would be very grateful for your assistance. I described it as follows: >Depending on the pipe type I leave the dispatch routine forwarding the >current Irp and device object to a validation routine for isochronous >transfers (because they are more complicated) or bulk transfer >completion routine. Isochronous completion is done as it can be seen >the original sample. Microsoft did in their samples the validation for >isochronous and both validation and transaction in the case of bulk >transfers in the dispatch routine. Although I copied and pasted the >whole algorithm from their (fine-working [standalone]) drivers, the system >crashes when I try to perform a bulk/isochronous read or write. What >rule did I violate? Moreover I recognized the same crash behaviour when I unplug one or both devices. I tried to get some debugging messages via DbgView from Sysinternals, but the system crashes, without storing the information into the given log file. I checked the in- and decrements on the stack without result. They seem okay to me. Since I solely introduced the validation routine for isochronous transfer and sourced the transfer algorithm of the bulk transmission out, I assume it must have something to do with the parameters I forward to these functions. I appreciate your help in advance, special thanks to Mr. Roberts who helped me this far. Tag: writing on Base Address Registers Tag: 72211

I need to give the IP datagram to the NDIS protocol stack then pass to Windows CE media player does anybody have any NDIS example for WinCE I can follow? I understand how to transfer data via SDIO interface the experience I am lacking is after I get the data how do I pass to upper layer protocol stack (NDIS) so when user want to watch live TV using windows media player they can do it. It should be similar to 802.11 just the out put from our chipset is IP packets not Ethernet packet Tag: writing on Base Address Registers Tag: 72209

hi,
how does a typical driver writes address on pci bus, i mean if i'm
targeting the address 01h
then could it be, 00000001h (32-bit AD bus in pCI).

Thx.

Address 1 on the PCI bus is part of the vector for INT 0.

If you mean address 1 within some device's address space, then your driver
will get resources in its AddDevice handler. The physical addresses from
the PCI BAR register will be given to the driver there. Your driver will
map that into kernel space, and access it through regular memory pointers.
