    - deleting a registry ke I save some device specific information in the registry that is created with ACCESS_ALL. Sometimes it is necessary go back to default configuration, so I would like to delete the information. I am opening an handle to the key and calling ZwDeleteKey, but I get an error with the status that I can't delete it (0xC0000121). The information has a tree structure (the key itself contains sub keys) and it also contains values. Is this the reason the delete fails? I can delete the node easily enough using regedit, why can't I delete it in my driver entry? Tag: can symbolicname be used to communicate with the device Tag: 99709

    - can symbolicname be used to get handle hi all, During the USB device design, a problem confused me. I want to get the handle of the USB device, and the symbolicname of this USB device in register, like following: \??\USB#Vid_xx&Pid_xx#x&xx&x&x#{xxx..} somebody told me, this symbolicname can be used in CreateFile to create the handle. After some tests (by change the symbolicname into the right form), I can use the "new" symbolicname in createfile, and the return handle is VALID_HANDLE. I want to know, is this symbolicname the right parameter in CreateFile? And the handle is which handle? Can this handle be used to communicate with the USB device? If it can, how?

    - how many sys file i need? Hi all: My device has to support xp32,xp64,vista32,vista64,so generally the solutions is to have 4 sys files for each OS: xp32.sys,xp64.sys,vista32.sys,vista64.sys(built with corresponding build enviornments) My question is: can i reduce my sys file numbers? for example,use vista x86 build enviornment,and this vista32.sys supports both xp32 & vista32. Is this possible?How to do? Or just one sys file to support all the OS,possible?? Thanks in advance. Tag: can symbolicname be used to communicate with the device Tag: 99703

    - Bootloader execution halts for DaVinci Board DM6446 with 64mb memo Hi, I am working on DaVinci Board DM6446. I have written a small utility program which loads my UBL in the SRAM and then loads the Bootloader in the memory on the address depending on the settings of .bib file and imagecnf.inc file while executing the Bootloader i.e. during the step of downloading the NK.bin file it stucks when it reaches to loading the record where actually the executables of bin are since the size is maximum in it. Also I am using a SDRAM of 64 mb only in the board.

    - How user wait for kernel? Hello, I am a new comer. I have a question: My user application need to wait for kernel interrupt and than do something. I think I will pass the request to kernel throught IOCTL call and wait for return. My kernel IOCTL function call KeWaitForSingleObject When interrupt happen, in ISR DPC, I will call KeSetEvent than my IOCTL function will return to user. Is this a good way to implement this? If not, what is the best way? Thanks, Xinshou Tag: can symbolicname be used to communicate with the device Tag: 99696

    - delreg section in INF not truly deleting registry entry I have a heisenbug I could use help on. I have service that creates several registry keys. The service has an associated INF file which has a DefaultUninstall section which is called by our product's installer when removing the service. The DefaultUninstall section calls out a delreg section which deletes about 20 keys from the registry. All but one of these keys gets deleted correctly. Now for the heisenberg portion of the bug. The installer prompts the user for a reboot at then end of the removal process. If I pull up regedit before saying yes to the reboot, the key in question is indeed not in the registry any longer and is not when the system comes back from reboot. If I do not pull up regedit and just reboot, the key is still present when the system comes back from reboot. Obviously, regedit is causing the change to be permanent in some way. Is there some lazy write problem here? Is there a way from the INF I can flush or commit the reg changes? Thanks. Bill M. Tag: can symbolicname be used to communicate with the device Tag: 99688

    - Verifier doesn't catch IRQL violation I accidentally called ZwReadFile at APC_LEVEL IRQL (holding a fast mutex actually) in a driver running on Vista RTM and got a weird result. ZwReadFile just wouldn't return. No crash, no bad status return, the thread just hung. Then of course the application was stuck with an open handle and neither the app or the driver could die properly. I turned on DriverVerifier for my driver with all options selected except low resource simulation and it never complained. It seems 1) ZwReadFile should be checking the current IRQL and returning a bad status if it isn't PASSIVE_LEVEL and 2) DriverVerifier should have caught this no? Just FYI to any MSFT folks that might care. I caught it pretty fast on my own, but this could cause someone no end of pain if they didn't know what to look for. Btw, this driver ran fine on XP SP2...don't know if that was (bad) luck or just a change in under arching operation. Haven't tried SDV on it yet. Bill M.

    - Language Monitor I wrote a language monitor for our custom made printers. It reads the status of the printer every 30 seconds and flag if there is a problem with the printer. Everything works fine, we can install different printers and it works. The problem is when I reboot my PC, only the first installed printer is seen by the language Monitor. I can see all the printers in the "Printers and Faxes" window, but only the first one that was installed is polled by the language monitor. I started our language monitor from the pjlmon example from WINDDK. -- Mario Tag: can symbolicname be used to communicate with the device Tag: 99677

    - Vista does not allow config space reads beyond 0xFF I have verified in winDBG in pci!PciExternalReadDeviceConfig that it checks the offset and verifies that the aligned offset is below 0x100. If it is at or above 0x100 then the returning status is 0xC0000010 or STATUS_INVALID_DEVICE_REQUEST which is exactly what I am getting. This is contrary to msdn documentation http://msdn2.microsoft.com/En-US/library/aa906253.aspx that says extended config space access is allowed: "Drivers can read from the extended PCI device configuration space (that is, more than 256 bytes of configuration data) using the IRP_MN_READ_CONFIG request or the GetBusData method of BUS_INTERFACE_STANDARD" Please tell me that I am wrong! I really would rather not calculate the offset from 0xe0000000 (using bus, dev, func) and manually read physical memory at that location to get to the extended config space. I WANT to use OS calls! Thanks. Gabe Tag: can symbolicname be used to communicate with the device Tag: 99670

    - Ethernet driver buffer allocation This may not be the proper spot to post, but I figured it was a good starting point. I also suspect this may be dependent upon the actual Ethernet device driver, and not an industry standard. That being said: When data is transferred across an Ethernet connection using, say a TCP-IP socket connection, the end caller issues a receive call, and passes in a pointer to a buffer where the data is written. My question is: a) Is the data being transferred ONLY written into that buffer which is passed in, or b) is there an intermediate buffer contained w/in the driver to store the data as it is transferred across the medium (and then copied into the buffer passed in on the receive call)? I am trying to minimize copies in my code, because I have large amounts of data being transferred. Again, I realize that this may be totally dependent upon the ethernet card being used, I just was curious if there was an industry standard, or some underlying protocol/handshaking to which I was not aware of. Thanks. Tag: can symbolicname be used to communicate with the device Tag: 99669

    - Getting started modifying a NT serial card driver to run on XP Hello I have the source code to a driver that works fine on NT4 but we now need to get it to work on XP. Our testing indicates that the driver does not work on XP. It is possible that it is a configuration issue however - as the driver gets some data from the registry - I am checking if we have that correctly configured. But I am guessing that is not the problem. Should a driver written for NT4 work on XP without change? The driver is for an RS422 multidrop card. Are there any areas of the driver code which I should be watching out for? Is this a total re-write situation or only minor changes? Any comments would be much appreciated.

    - Can't get reading extended config space to work on Vista I am pretty sure that the BIOS is allowing Vista to take control of PCIe since in WinDBG I can do a !pci 0x101 3 0 0 (my device is on bus 3, dev 0, func 0): ..[Config Space 0x00-0xFF omitted]... Enhanced Capabilities: 100: CapID 0002 Virtual Channel Capability Version 1 NextPtr 800 800: CapID 0001 Advanced Error Reporting Capability Version 1 NextPtr 000 However on another machine running Vista where I'm pretty sure the BIOS does not do the _OSC method and I think it is verified when I run !pci 0x101 on the same device there will be no "Enhanced Capabilities listing at all. Neither of the two Microsoft sanctioned ways (that I am aware of (i.e. GetBusData and IRP_MN_READ_CONFIG)) to access extended config space worked for me. I have even used the example verbatim from http://msdn2.microsoft.com/en-us/library/ms795302.aspx. The status returned from the IRP_MN_READ_CONFIG method is STATUS_INVALID_DEVICE_REQUEST. I've even tried installing Vista SP1 Beta, but the results are the same. Any other venues I should take/investigate? Thank you in advance.

    - missing DirectoryChange notifications Hi all, I'm writing an IFS minifilter doing some HSM stuff. Most operations are queue using FltQueueXXX functions. In worker function changes to files are done using e.g. FltSetInformation, FltWriteFile. This works very well. But user mode applications using NtNotifyChangeDirectoryFile or ReadDirectoryChangesW (e.g. Explorer) are not notified about these changes. Changes on files triggered from any user mode application are notified! How can I notify changes from IFS filter (system thread)?

    - Multple LUN support question for USB flash drive Hi, I'm trying to expose a USB composite device with the mass storage interface at interface 2. Although I reported support for Hierachial support (HiSUP bit set to 1), the system does not try to query me for my other LUNs except for LUN 0. I never received the REPORT LUNS command that is suppose to be compulsory when HiSUP bit is set. When I change the mass storage interface to interface 0, I get the INQUIRY command for LUN 1 as well and all is well. Question is, why doesn't the system check for additional LUNS when my mass storage interface is not 0? Is this a requirement? Thanks.

    - FTDI's FT232R chipset Junk data bytes Hi All, I am writing a Custom WDM USB-UART driver(Single VIRTUAL COM PORT) for FTDI's FT232R chipset. In my InitializationModule() and startdeviceroutine() I could able to Get the device descriptor and configure the Device perfectly. I am getting the Interface and pipe information correctly. My problem is after start device, If I try to Read data from the device by calling the following //Satrt the request ulFlags = USBD_TRANSFER_DIRECTION_IN | USBD_SHORT_TRANSFER_OK; UsbBuildInterruptOrBulkTransferRequest(pCtx->m_pUrb, sizeof(struct _URB_BULK_OR_INTERRUPT_TRANSFER), hPipe, pbBuffer, NULL, cbBuffer, ulFlags, NULL); // Setup completion proc IoSetCompletionRoutine(pCtx->m_pIrp,(PIO_COMPLETION_ROUTINE) RequestCompletedThunk,pCtx,TRUE,TRUE,TRUE); // Call next device with this IRP status = IoCallDriver(pCtx->DeviceExtension- >TopOfStackDeviceObject, pCtx->m_pIrp); in My Completion routine I am getting 2 bytes of junk data, Which is unexpected(There is no data kept in port). When I open the Virtual Com Port and write some data bytes, still I am getting these 2 junk bytes. I tried to resolve this issue by resetting the pipe. Still problem exists. Can anybody help me to get rid of that unnecessary junk bytes. Your valuable suggestions are always appriciated.

I want to reinvent the wheel, just as the COM d3d api usermode dll is one alternative to get to the driver, I want to make my own alternative. However I don't know how to do this. It all starts with an application in usermode loading my usermode dll providing an alternative to the COM api. How does my usermode dll penetrate into the kernel driver ?

My notebook is the host and a 4-pin connector on the notebook and a 6-pin on the desktop adapter connects the two machines. Unfortunately, it's not working. Could some of you share the hardware specs of a 1394 PCI adapter for a desktop, and the cable specs, that you've used? I'd have to buy the stuff again.

I've rebuilded the source code to do the modem test in Windows Vista. But it didn't work in Windows Vista x86 and x64. It was working a few months ago in Windows Vista. As of present, Suddenly it didn't work in Windows Vista. After executing RasDial function, it showed up the error message as belows: The specified port is already in use or is not configured for remote access dial-out. I checked communicating from the device by Dignosis Tool. The device is worked to reply for AT command. I don't know why. Could you explain me about this situation? I'm very confused this situation.

    - TDI listen hangs. How to know, why? Hello, I try to make my TCP TDI client to listen for connection (that is I try to bring the server side of the connection up). This is, I hope, 5 steps process: 1) Open transport address. (I use 0.0.0.0:5000) 2) Open connection endpoint 3) Associate transport with the connection 4) Hook some event grabbers (I have set event handlers for TDI_EVENT_CONNECT and TDI_EVENT_RECEIVE) 5) Listen... The first 4 steps of the 5 succeed, but the last TDI_LISTEN CallDriver return STATUS_PENDING which never ends. (below please find a code fragment). I expected that TDI listen request must never hang, because this is (i hope) a transport service "mode" setting only. What could be the reason for it to hang? How to make the server listen? Please help. (probably somebody could post few lines of sample code) Thanks, Sergei. //----------------------------------------------------------- //------------------------------------------------------------ // // Tdi_Listen // NTSTATUS Tdi_Listen(PFILE_OBJECT pConnection) { NTSTATUS NtStatus = STATUS_INSUFFICIENT_RESOURCES; PIRP pIrp; PDEVICE_OBJECT pTdiDevice; TDI_COMPLETION_CONTEXT TdiCompletionContext; TDI_CONNECTION_INFORMATION ConnectionInfo_ret; TDI_CONNECTION_INFORMATION ConnectionInfo = {0}; IO_STATUS_BLOCK IoStatusBlock = {0}; ULONG User_D = 0x40404040; // a "don't care" value // PAGED_CODE(); KeInitializeEvent(&TdiCompletionContext.kCompleteEvent, NotificationEvent, FALSE); // // TDI Device Object to send requests to the TDI Driver. // pTdiDevice = IoGetRelatedDeviceObject(pConnection); // // Build the IRP. // pIrp = TdiBuildInternalDeviceControlIrp(TDI_LISTEN, pTdiDevice, pConnection, &TdiCompletionContext.kCompleteEvent, &IoStatusBlock); if(pIrp) { // // Add the correct parameters into the IRP. // ConnectionInfo.UserData = &User_D; ConnectionInfo.UserDataLength = sizeof(ULONG); ConnectionInfo.Options = NULL; ConnectionInfo.OptionsLength = 0; ConnectionInfo.RemoteAddress = NULL; ConnectionInfo.RemoteAddressLength = 0; TdiBuildListen(pIrp, pTdiDevice, pConnection, NULL, NULL, 0, // Flags, &ConnectionInfo, &ConnectionInfo_ret); // PTDI_CONNECTION_INFORMATION NtStatus = IoCallDriver(pTdiDevice, pIrp); // // If TDI_LISTEN will not hang I'll have BSOD(CC01). // if(NtStatus == STATUS_PENDING) { KeWaitForSingleObject(&TdiCompletionContext.kCompleteEvent, Executive, KernelMode, FALSE, NULL); NtStatus = IoStatusBlock.Status; KeBugCheckEx(0xDEADCC01, 0, 0, 0, NtStatus); }else{ KeBugCheckEx(0xDEADCC02, 0, 0, 0, NtStatus); } } return NtStatus; } // Tdi_Listen Tag: can symbolicname be used to communicate with the device Tag: 99488

    - FILE STREAMS:??? I'm trying to use an alternate data stream to contain information about some files I wish to manage. However I am very confused about certain semantics. In particular if FileA has an alternate stream Meta, then I might have two streams FileA (FileA::$DATA) and FileA:Meta. When FileA is opened for write, it seems that FileA:Meta is getting nuked. I would like to get a better understanding of the conditions under which FileA::$DATA can be written to without disturbing FileA:Meta, etc. Also, what about security? Can I set more restricted privileges on FileA:Meta than on FileA::$DATA Is there documentation for any of this beyond a few toy examples? -- Gak - Finecats Tag: can symbolicname be used to communicate with the device Tag: 99487

    - Disable Device is persisted, but where? Hi, On Vista, if I go to Device Manager and disable a device, then reboot, the device is _still_ disabled. My question is where is this config change persisted? (e.g. in the registry or FileSystem) I guess it will initially write the change to the volatile area in the registry CurrentControlSet\Enum\..., but it does not appear to write the change to the related keys under the hardware profile area of the registry. I therefore don't understand how it can persist across a reboot? -- Gerry Hickman (London UK) Tag: can symbolicname be used to communicate with the device Tag: 99475
