    - Work with driver by User without admin rights Hi ! I want to allow user ( without admin rights ) access to device object of the NDIS miniport driver ( use PCI card ). I changed permissions of the driver to full for users and that work. I read that the same possible to do by INF : 1) http://www.microsoft.com/whdc/driver/security/drvsecure.mspx?pf=true#secmod2 show the example line: HKR,,Security,,"D:P(A;;GA;;;SY)" So I wrote next in the INF [mydevice.Security] HKR,,Security,,"D:P(A;;GA;;;WD)" In the registry I see Key "security " with a string - "D:P(A ( 6 characters ) Before I tried AU instead of WD with the same effect 2) http://msdn.microsoft.com/library/default.asp?url=/library/en-us/setupapi/se tup/specifying_a_security_descriptor_from_an_inf_file.asp show line : "D:P(A;CI;GA;;;BA)(A;CI;GA;;;SY)" I wrote next [mydevice.Security] "D:P(A;;GA;;;WD)" Cannot correctly install driver at all Any comments ?

    - USB device and timeout Hi all, I develop a USB device. I would like to know, what to do, if I send a IRP for IN transfer (OUT transfer) from my USB driver to lower level driver and my USB device doesn't send (receive) any data (only "NAKs" are on the USB bus). Therefore should be useful to set a timeout. Is it possible to set the timeout in my USB driver or firmware in the USB device sould resolve this problem? If I use something like this: ... ntStatus = IoCallDriver(pdx->StackDeviceObject, irp); if (ntStatus == STATUS_PENDING) { status = KeWaitForSingleObject( &event, Executive, KernelMode, FALSE, &timeOut); if( status == STATUS_TIMEOUT ) { IoCancelIrp( irp ); KeWaitForSingleObject(&event, Executive, KernelMode, FALSE, NULL); } } on win98 if I set the timeout about 100ms has been result BytesTransfered = urb->UrbBulkOrInterruptTransfer.TransferBufferLength; 0x400 but through USB bus has bees transmitted 0x440 bytes. I don't know why this situation occured. Does anybody help me please? Thanks a lot Slavo Tomascik msonetime@zoznam.sk Tag: PCI_COMMON_CONFIG Tag: 44566

    - Device Manager and devcon do not remove driver service entries for PNP drivers on uninstall It seems that the Device manager and devcon.exe do not actually remove the service associated with a driver when uninstalling a device from the system. Additionally, it does not look like the SetupDi... api supports this functionality. Both tools are properly removing device instances in my case, but the service entries are left behind in the registry, and the driver binary files are left on the system. This happens on both XP and W2K3. Looking through the docs there doesn't seem to be a PNP way to remove them. DeleteService() and manual delete of the binaries seems to be the only way to get everything off the system. There is an api to remove OEM .inf and .pnf files, but not a driver service or binaries. Is this on purpose, or was this an accidental omission from the PNP install support? Is this going to be a problem in WHQL validation of a driver package? Is there something I'm missing?

    - software raid0/striping on C: ? My topic here is to discuss why microsoft does not implement the ability to utilize at OS-Setup two disks as raid0/striping. Yes I know, raid0 is not safe, or at least is just as safe a a 1-disk which is the most popular solution for 99% of the users in the desktop computing. So why after all not allowing this ??? I think users should be allowed doing this, assuming the risks on their own. the fact of the matter is that nowadays everybody may afford a couple of hard drives and if put on different IDE channels/perhaps controllers they could 'fly' with raid0. This limitation indeed exixts within the Redhat/Fedora implementations too as well as others, but just because of 'lack of care' for those requirements that many users would appreciate instead if given the chance. Slackware Linux on the other hand SHOWS that it is possible to in fact have two separate devices paired as raid0 mounted on / (equivalent to c:) This raid0/striping on boot/root is way possible, I am a linux guru too, although I love and prefer Microsoft, and since it's possible because I made it and used it, I am wondering if this limitation is made perhaps because the microsoft's disk structure/software could not handle this at all unlike linux.

    - Legacy driver "cannot find the device specified" Hi All - First my apologies I am not a driver developer, but I hope some of the experts on this group can help! I have an XP machine on which the Microsoft userdump utility fails to install. The problem appears to relate to userdump.sys, installed as a legacy kernel mode driver. This will not start, and on boot-up or attempting to start (via the service userdump.exe which depends on it) SCM logs "The system cannot find the device specified". sc query udmpdrvr shows it stopped with WIN32_EXIT_CODE 20, which I think means the same. During an attempt to start it, Regmon shows an enum\root subkey LEGACY_UDMPDRVR being created by Services.exe, but it is then promptly deleted again. Can anyone please suggest ways of troubleshooting this issue, or suggest what might be going wrong? Thanks in advance - Mike. Tag: PCI_COMMON_CONFIG Tag: 44515

    - [XP] disk class filter & FAT32 Hi, I recently wrote a disk class upper filter driver. It starts at boot time! The very strange problem is that it is somehow dependent on the file system of the host system. case 1: WinXP is on a NTFS partition -> no problems at all case 2: WinXP is on a FAT32 partition -> I get 0x0000007b meaning INACCESSIBLE_BOOT_DEVICE. Since the filter only acts on disk class devices it shouldn't depend on the filesystem, right? Any ideas about that? regards M.O. Tag: PCI_COMMON_CONFIG Tag: 44514

I searched the archives but the threads i found talked only about communications among drivers lying on the same stack. If i have to route packets coming to the NIC to some other PCI device so that it can process them, how do i call that PCI device's driver's functions and pass them the packet data so that it can process them and then return them back and i can pass them over to the NIC. I am using the DDK's sample "NDIS passthru intermediate driver" for hooking the packets and now want to call the other PCI card's functions to process those packets before sending them over i dont know much about drivers. is there a way i can get the other driver's handle from the kernel and call its funcitons any help will be appreciated. and since i am a novice therefore details are welcome taj.

    - Help, why PCI bus master memory read fails, many retries? I have a PCI device that seems to be unable to read from main memory but only after a large amount of virtual memory has been freed up by an unrelated application. This is on Win XP. I'm new to Windows drivers so don't know all the terminology and have hunted google for this answer without success. The PCI device is controlled with a Jungo based WinDriver and peridically the PCI device reads a few words from main memory so it knows what to do. The driver when opened has used Jungo's WD_DMALock() call to lock the pages in physical memory. All seemed to run well for 6 months until a new big application that allocates a lots of memory came along. And it is only when that big application exits that the problem occurs. It seems like a virtual memory management thing is getting in the way. Anyway, the PCI bus analyzer shows that the PCI device tries a bunch of times (currently 127 retries) to read from main memory and eventually gives up when all reads timeout. So what is going on?

    - Newbie Q : TDI driver communicating with user app? Hi, I'm totally new at this, so please forgive the basic question. I am attempting to modify a TDI filter driver so that it communicates with a user mode application to do some processing of the data. Based on the application's response, the driver will change some of the data before forwarding on the rest as usual. It seems that I can share the data with the app by making DeviceIoControl() calls to pass in a buffer to the driver to fill in and then for the app to send its response after it has completed its analysis. An article, http://www.osronline.com/article.cfm?id=108, suggested using named events created by the app to control access to shared buffers, so I attempted to incorporate that. My problem is that the driver, while it's fetching the data, can't seem to wait on a named event. However, if I stick in a KeWaitForSingleObject() within the handler for the command sent by DeviceIoControl(), it seemed OK. Does this sound like the right approach? What am I missing? Thanks for any help. V Tag: PCI_COMMON_CONFIG Tag: 44433

    - CIS in common memroy Does Windows occasionally access CIS on other times then at start up (power-up)? I'm interrested in this because I'm thinking of loading CIS into my 1 KB SRAM during power-up, which is the only space on the card that is used by the PC card interface. And then remove the CIS, after Windows have read all it need, to make the space avalible for registeres that is needed for the cards original function. Needs all of the 1KB space. (The PC Card have the logic that supports this replace-idea, but those Windows/ PC Card standard support it?). This implies that the CIS have to be in common memory. Tag: PCI_COMMON_CONFIG Tag: 44410

    - how to match usb vid/pid with mass storage drive letter in win98 Hi I would like to find the drive letter assigned to my usb mass storage device. In win2k/xp, I can use QueryDosDevice and the SPDRP_PHYSICAL_DEVICE_OBJECT_NAME registry property to find the drive letter. But in win98, I have encountered a few problems using the same method 1. QueryDosDevice always give me back the device name. e.g.: i use "c:" as input, the function will give me back "c:". Is it a normal behaviour in win98 2. I use umss as the driver of my device so I cannot find the volume interface of my device. So how can I get the SPDRP_PHYSICAL_DEVICE_OBJECT_NAME of my device in order to compare with the returned value from QueryDosDevice 3. I do not know whether I should also use this method in win98 or not. Is there anybody who have tried this I am just a newbie. Can anybody give me some hints?

    - Accessing floppy disks with 10 sectors per track Hi, I've got some old double-sided double density disks that are formatted with 10 sectors/track rather than the standard 9. Do anyone have any ideas how I could read/write these under 2000/XP? I noticed from looking at the DDK that flpydisk.sys doesn't support this layout. I was wondering whether it's possible to write some sort of simple filter driver to tell it about the extra sector per track? Just in case this is important, sector ids run 1 through 10, track numbers (in the sector headers) run 0-79 on side 0 and 128-207 on side 1. Actually, it would be really handy if I could get at the actual sector headers as well as the data... Regards, Jonathan Needle Tag: PCI_COMMON_CONFIG Tag: 44392

    - Question about system page table entries Hi reading about terminal server sizing I recognized the term "system page table entries" quite often. Unfortunaltey I understand the 4 GB virtual memory is devided into 2 GB users space (a private space for each process) and a 2 GB system space. Page table entries are used to map virtual memory addresses to physical ones. From my understanding, system page table entries are used to map the complete 2 GB system space to physical memory and normal PTEs describe the users space. I heard SPTEs are a limited resource and the OS is not able to use the complete 2 GB space due to this limitation If I'm wrong and SPTEs describe only portions of the system space, which portions are described? Why isn't it possible to use just PTEs I appreciate your help Stephan Tag: PCI_COMMON_CONFIG Tag: 44391

    - How to Set default audio device? Hello to all, I need your help. I'm programming in VC++ and I need to change the default audio device in Windows98, 2000 and XP. I've found a function that returns the ID of the preferred audio device (waveoutmessage) but I need to change the preferred audio device. I don't know how to do that... may be It can be done through the registry... Thank you. Tag: PCI_COMMON_CONFIG Tag: 44385

    - question about using VC6 with DDK Hello, i just bought Walter Oney's book on WDM drivers. so far it is really good, but i am just at page 100. at this moment i have 2 question: - in the introduction Walter says that he uses VC6 for programming and building device drivers, but i havent found am explanation so far that tells me how to set this up. is it enough to just change the compiler? and what am i supposed to enter for build target?is it enough to use the VC6 plugin or do i need to do more? - is it possible to use VC .NET 2003 instead of VC6? i still use both on my system, but i would rather move to VC .NET where possible. i am sorry if i ask questions that are answered in the book, but i have skimmed through it to see if they were, and did not find anything. i have not read the book completely, but wanted to compile an empty example to get a feel for it. rather than taking a finished example from the CD, i would build an empty driver myself so that when it is finished, i would really know what was in there. kind regards, Bruno.

    - Bluetooth HCRP credit flow Hi Folks, I am developing an HCRP firmware (Printer side HCRP profile) and testing it against the XP Bluetooth HCRP driver. I am successfully able to - have the XP host detect my device as a "HCRP Printer", - the L2CAP Control and Data channels getting created - a new printer also gets added to my "Printers and Fax" collection on the HCRP Host. Now When I try and print a document using this HCRP printer following happens: a. I get a CR_DataChannelCreditRequest on the L2CAP COntrol Channel (Printer side) to which I reply with a large number of credits (0x00 00 00 00 00 FF FF FF). b. I start recieving bytes on the L2CAP Data channel. c. After recieving 64KBytes, the Host application doesnt send any more packets. Neither any bytes on Data Channel, nor any more CR_DataChannelCreditRequest. However I recv. all the data for if the print data is less than 64K, my question is this 64K any magic number ? IMO I should be getting periodic requests for credits on the Printer side after the HCRP Host has exhausted all the credits, but no such thing happens. How has the HCRP driver in XP been implemented to handle this situation ? I have also tried sending some credtis (voluntarily) from the printer side to the Host using the CR_DataChannelCreditGrant after the 64K bytes of credit have been exhausted, but to no avail. help in any direction appreciated. thanks people for all your patience.

    - Bypass print processor Hi I have a customized print processor associated to a printer. That print processor copies the Spool files of jobs printed by users. In another application, users will take actual print outs with those spool files using the same printer. When they are actually printing, I should bypass printprocessor (Otherwise, it again copies the spool files). How to write RAW data directly to Port monitor/Printer, bypassing the print processor In my application I tried like this StartDocPrinter() StartpagePrinter() Read the spool file() WritePrinter(); // Tried printer name, Port name. Both are spooling the data.1 loop until end of file EndPagePrinter() EndDocPrinter() In the above approach, printprocessor is getting invoked. Also I tried different spooler properties like Print directly to printer. That too didn't work Is there another approach all together(My client does not want 2nd printer associated to another print processor) Thanks & Regards Kira Tag: PCI_COMMON_CONFIG Tag: 44374

PCI_COMMON_CONFIG structure does not have a type1 UNION defined? how TYPE 1 headers are used in a driver?

My guess is that you are including WDM.H. Include NTDDK.H instead.

Thanks Eliyas, ntddk.h has both types defined, I was looking in the DDK documentation and it only defines type 0 in the PCI_COMMON_CONFIG reference section.
