    - problem using a standalone device object with NDIS Hello, I have a problem when using 'NdisMRegisterDevice()' in my NDIS driver. I use this call to create a standalone device object so that my application can communicate with my driver. Using this, I can communicate with my driver fine from my app. However, the file handle that my application creates to talk to my driver does NOT get notified when I register to receive device notifications using 'RegisterDeviceNotification'. However, if I create a handle using the REAL device name (obtained by using the SetupDixxx functions), my app properly receives the notifications. I can't use this handle tho', 'cuz NDIS owns it and my driver won't received Irps sent to it. The basic problem I'm trying to solve is this: if the device is unplugged WHILE the app is running, the app needs to close the handle to allow the driver to unload.

    - Getting quick IP address on P2P RNDIS network There is a small problem that we've run into, which I hope somebody can help us with. We have a USB device, which supports RNDIS and that causes an XP machine to create a separate network for it. The device also creates a "remote" node on that network essensially establishing point-to-point network inside the device itself. Now to the problem, how do we quickly assign IP address to this network? I am looking for any suggestions - from totally legal to semi-legal. So far this device is restricted to a lab environment, but having fully supported solution is obviously preferred. Static IP assignment is out of question. So is auto IP as it is too slow. We need to be able to assign a address in a matter of seconds or even faster. Also a requirement - multiple instances of this device can be connected to the same machine and they all have to sit on separate networks and don't conflict with each other. The only solution that I can think of at a moment is to have the device being a DHCP server for its own net. Problem: multiple devices can be connected to the PC and there must be a solid algorithm in place to avoid any conflicts. I was also told that IPv6 would solve this issue. This is very generic problem and I am sure there are good solutions to it. Can anybody offers any suggestions or refer me to relevant RFC or something? Any help would be appreciated. Thanks! -- Max.

    - DIFx Framework - HOWTO Hi All, First, I have only a basic understanding of the certificates, signing, etc. so please excuse me if some question appears to be a stupid one :-) I'm evaluating the MS DIFx framework as to make a single file installation of the driver I've made. In connection with this I have tried to set-up an installation through DIFx framework but have some troubles with it. I get the following error in DpInst.log file for every INF file in the driver: "ERROR: driver package 'drive:\path\INFFILE.INF' is unsigned. Error code 0x800B0100, No signature was present in the subject." Could somebody explain me what is the right way to set-up the installation. - As far as I know only the cat file should be signed not all the files in the driver package... Follows a short description of how I've tried to make the installation: In the INF file I have included the requested CatalogFile and DriverPackageType sections: CatalogFile=CBMA.cat DriverPackageType=PlugAndPlay The content of CBMA.cdf file is: [CatalogHeader] name=CBMA.cat [CatalogFiles] CBM.dll=CBM.dll OEMUI.dll=OEMUI.dll OEMUNI.dll=OEMUNI.dll CBM.ini=CBM.ini CBM_CT1000II.INF=CBM_CT1000II.INF CBM_CTS300.INF=CBM_CTS300.INF CBM_PPU700.INF=CBM_PPU700.INF CBM1000II.GPD=CBM1000II.GPD CTS300.GPD=CTS300.GPD PPU700.GPD=PPU700.GPD ttfsub.GPD=ttfsub.GPD CBMA.HLP=CBMA.HLP eula.txt=eula.txt From this file I have successfully created .cat file and subsequently signed it with a test certificate obtained through makecert.exe and cert2spc.exe... After that I copied DpInst.exe in the driver directory and made eula.txt and dpinst.xml files. Subsequently when I ran DpInst.exe I received the described error. Any help will be appreciated! 10x ___________________________________________ Best regards, Ivan Dimitrov Tag: How do you tell WZC that our driver/adapter is WPA compliant Tag: 50299

    - DPC has high latency only with SMP Hallo, i'm back with my DPC latency problem: i'm testing my driver on an SMP machine, and 4 or 5 times every second when in the isr i request the dpc, i find that the old request is still in queue. When I start the OS with the /onecpu option, this behaviour disappears and the DPC is never delayed too much (>1ms). Does anyone have some clue for solving this problem ? I don't understand why the dpc handling seems to slow down so much on a SMP machine. Thanks, e. Tag: How do you tell WZC that our driver/adapter is WPA compliant Tag: 50298

    - [Q] how can i get the CR3 value? Hello all. I have a question about getting cr3 value. (page directory base address) In softice, the 'PAGE' command shows the cr3 value exactly. (on windows 2000, 0x30000. on windows xp, 0x39000) But, my driver can't catch the value. (0xb9e83d8f <- like this) the code is this. push cr3 pop eax it doesn't work. I think this is because my driver is called in a user process, not in kernel. so, my question is this. is there any way to get the cr3 value of the kernel? (running a thread in kernel?) if no, how can i use the same method like softice's. thanks for reading. Tag: How do you tell WZC that our driver/adapter is WPA compliant Tag: 50295

    - network link speed Hello, does anyone know how the link speed is determined by Windows when attached to a wireless network? I know Windows queries the Ndis driver using OID_GEN_LINK_SPEED, which is supposed to return the max Tx rate. In a wireless network, the max rate is determined by the Service Set. Therefore, I would assume that when associating with a particular Access Point, I should always get the same link speed. However, I've seen cases where the link speed changes between 1, 2, 5.5 & 11Mbps - even though I'm still connected (i.e. no disassociation/reassociation occurs). My service set consists of a single Access Point, which is configured to use all 4 rates (i.e. they're all marked Mandatory in the beacon parameter set).

    - scsi troubles... Hi folks, my (first attempt of a) pcmcia scsi miniport driver is driving me insane... The driver consists of only a DriverEntry() - which initializes a HW_INITIALIZATION_DATA structure - and a few (empty) functions for the drivers entry points. (As seen at MSDN->SCSI Miniport Drivers). Here's how the initialization of the HW_INITIALIZATION_DATA structure looks like: ULONG DriverEntry(IN PVOID DriverObject, IN PVOID Argument2) { HW_INITIALIZATION_DATA InitData; ULONG Status; ULONG i; for (i=0; i<sizeof(HW_INITIALIZATION_DATA); i++) ((PUCHAR)&InitData)[i] = 0; InitData.HwInitializationDataSize = sizeof(HW_INITIALIZATION_DATA); InitData.AdapterInterfaceType = PCMCIABus; InitData.DeviceExtensionSize = sizeof(MY_DEV_EXT); InitData.NumberOfAccessRanges = 2; InitData.HwFindAdapter = FFS_FindAdapter; InitData.HwInitialize = FFS_HwInitialize; InitData.HwStartIo = FFS_StartIo; InitData.HwResetBus = FFS_ResetBus; InitData.HwAdapterControl = FFS_AdapterControl; InitData.HwInterrupt = FFS_Interrupt; InitData.HwAdapterState = FFS_AdapterState; InitData.HwDmaStarted = NULL; Status = ScsiPortInitialize(DriverObject, Argument2, &InitData, NULL); __asm int 3 return(Status); } The bare minimum inf file to install my bare minimum driver looks like this: [Version] Signature="$WINDOWS NT$" Class=MTD ClassGuid={4D36E970-E325-11CE-BFC1-08002BE10318} Provider="Mike" DriverVer=08/14/2004 [DestinationDirs] DefaultDestDir=12 [Manufacturer] "Flashcard"=DeviceList [DeviceList] "PCMCIA Flashcard"=DriverInstall,PCMCIA\UNKNOWN_MANUFACTURER-0000 [DriverInstall.NTx86] CopyFiles=@ffs.sys [DriverInstall.NTx86.Services] AddService=ffs, 2, ServiceInstallSettings [ServiceInstallSettings] DisplayName = "PCMCIA Flashcard" ServiceType = 1 StartType = 3 ErrorControl = 1 ServiceBinary = %12%\ffs.sys LoadOrderGroup = SCSI Miniport Dependencies = PCMCIA AddReg = ServiceRegistryEntries [ServiceRegistryEntries] HKR, "Parameters\PnpInterface", "8", 0x00010001, 0x00000001 The driver is ment to be pnp compliant as the PnpInterface registry key and the presence of the HwAdapterState-function indicate. After the driver is installed and a memory card is pluged in, the drivers DriverEntry() function is called and ScsiPortInitialize() returnes a value of zero. (Which seems to be ok). But after that, no other function will be called! The main question is: Why is no other function than DriverEntry() called? Acording to MSDN this may happen if PnpInterface is present but the driver is not installed as a service for the device. Which leads directly to the question: The above inf file should install the driver ffs.sys as service (with the name 'ffs') for devices of type PCMCIA\UNKNOWN_MANUFACTURER-0000. Is this the case? Or do you see any mistakes? (I used msdn and Oneys WDM book to 'tinker' the above inf file together, but it's well possible that i've missed something... ?!?) I have no idea why my driver does not initialize proper. Maybe a legacy driver would be a better idea than a pnp driver... Please let me know if you have any advice.

    - USB Driver : 0xC0000B00 + 0xC000A00 errors with Isochronous OUT Endpoint when ASAP is specified ! Hi, My device supports an Isochronous OUT Endpoint, set to 895 bytes/ms.

Each URB also gets completed but some are completed with 0xC0000B00 error (USBD_STATUS_ISOCH_REQUEST_FAILED). For those URBs that fails with this error, Iso packets (that do not have data) are told to be in error (0xC0000A00 = USBD_STATUS_BAD_START_FRAME), whereas all URB are sent with the USBD_START_ISO_TRANSFER_ASAP flag.

    - Using DIFxApp for Net Client install I've been trying to use the DIFxAPP code to install our NFS Client Device driver and have been running into problems. The DIFxAPP code requires a WHQL digital signature.for use with Windows 2000 and XP. Since we have no hardware we cannot take advantage of that program. An Authenticode signature can be used for Windows Server 2003, but apparently not for Win2k and XP (According to the Authenticode doc anyway). Has anyone else run into this problem? Any workarounds? Does anyone know why a WHQL digital signature is a requirement? Any idea if this requirement might be relaxed in the future? The error that cat get past is 0x800B0100L which is "No signature was present in the subject." I have supplied an Authenticode signiture, so I'm guessing that it wants a WHQL digital signature, correct? Regards, Duane Johnson WRQ, Inc.

    - Terminal Server, virtual audio driver, and lossless audio I was unable to locate a better newsgroup, so if there is a better place to post this question, please let me know. I am working with streaming audio over a Terminal Services connection in Windows 2003 Server. However, the application we'd like to use will be used in an audiological setting, so having lossless audio is of paramount importance and there doesn't appear to be a way to configure the virtual audio driver to use a lossless codec for transmission across the network. My question, then is this: Is there a way to configure the virtual audio driver for Terminal Services to use lossless compression? If not, to whom would I speak in order to have this option implemented in a future version? Thank you for your time in this matter.

As I'm running on DISPATCH_LEVEL, I need to specifiy NonPagedPool as a pool type. But as I'm allocating rather a big amount of memory, I'd prefer a paged pool allocation. Is there any way to do this in DISPATCH_LEVEL? Thanks to everyone Sam Tag: How do you tell WZC that our driver/adapter is WPA compliant Tag: 50206

    - Ndis packet user mode round-trip Suppose you have a Ndis IM over a Gigabit NIC. The IM sends all packes to user-mode then a console application will write the packes to the IM that will send them. What would be the resonable lowest degree of performance degradation one could expect from this scenario? Tag: How do you tell WZC that our driver/adapter is WPA compliant Tag: 50180

    - bug (?) in SfGetFileName in the SFilter sample, SfGetFileName will produce a string from various pieces. It gets a device name, a related file name (if any) , and then the filename and glues them together. I'm seeing that when a file from the network is being written, the device is \device\harddiskvolume2 then the related file object is '\' and then the routine appends a \ also finally the file name is \test\alpha.txt. This results in a name = \device\harddiskvolume2\\\test\alpha.txt. Can this possibly be correct? -- Gak - Finecats Tag: How do you tell WZC that our driver/adapter is WPA compliant Tag: 50163

    - IOCTL and mutex Hello I guess I am little confused and would appreciate if someone were to help me resolving this. I have written a driver for PCI based device to be meant to be used on Windows 2000 and up. The device has a few controls that the user application can get and set through IOCTL interface that I have provided in the driver. In order to serialize access to ioctls, I use Kernel Mutex as shown KeWaitForMutexObject(&pdx->ioctlMutex, Executive, KernelMode, FALSE, NULL) ; /* do stuff */ KeReleaseMutex(&pdx->ioctlMutex, FALSE) ; I could have used spinlocks but I reasoned that Mutex would work just as fine in this case because driver would not be in an arbitrary thread context while processing IOCTLs and I could spare raising the IRQL to DISPATCH. Also, I should mention that my driver installation does not put another filter driver on top of my driver. Now I am wondering if my above reasoning is indeed correct. In other words, can it ever happen that, either on XP or windows 2000, the driver receives IOCTL in an arbitrary thread context in which case I should probably switch to using spinlocks.

    - Restarting a print job I work for a small printer manufacturer as a software engineer developing. I'm currently modifying a USB print driver to add an error recovery capability, it should allow a job to be reprinted from the same page where an error happened. I've already implemented this feature for a parallel port driver but I'm facing some problems now that I'm trying to do the same for USB port. The problem is as follows: 1. When an error condition is detected the Language Monitor's WritePort function stops sending data to the printer but keeps reading data from the print spooler unitl it detects an end-of-page token. 2. When this happens I set the job to be restarted using the SetJob function using the command JOB_CONTROL_RESTART. 3. I can see in the print queue the job restarting and respooling. The print spooler starts sending data again to the Language Monitor. 4. This is when the error happens. The WritePort returns error 183, which is "Cannot create a file when that file already exists". So, I read some documentation and tried some option without much success. My best gess is that the print processor is not being restarted. There is two files (FP00000.SPL and FP00000.SHD) that are never deleted as the way the should when this error happens. I tried to use the ControlPrintProcessor() function to terminate the print processor manually when the job is done, but I couldn't get the correct handle. Did some one have this problem before? any suggestions? Sincerely, Fabio Milan Tag: How do you tell WZC that our driver/adapter is WPA compliant Tag: 50159

    - Device Initialization File I am trying to have my driver read a .ini file and apply the described settings to hardware. Are there any routines available, similar to GetPrivateProfileInt and GetPrivateProfileString, that are available to drivers? If not, any suggestions on how to parse individual lines?

    - Problem with linked list Hi again, I implemented the following double linked list stuff: typedef struct __MYSTRUCT { UINT t; [...] UINT bufferlen; //length of buffer BYTE *buffer; }MYSTRUCT; typedef struct __MYLIST{ MYSTRUCT mystr; LIST_ENTRY linkfield; }MYLIST, *PMYLIST; LIST_ENTRY DoubleHead; ------------------------------------------------------- [...] MYSTRUCT a; //filled with data /*The size of all the entries is dynamic, that's why the size of the structure is allocated again every time*/ UINT structsize = sizeof(UINT) + sizeof(UINT) + sizeof(a.buffer) + a.bufferlen; PMYLIST psElement = (PMYLIST) ExAllocatePoolWithTag(PagedPool,structsize,'HASA'); //here we CRASH!!! if(psElement == NULL) { DBGPRINT(("Allocatepool failed!")); } else { psElement->mystr = a; NdisAcquireSpinLock(&GlobalLock); if(numberofentries <= MAX_LIST_ENTRIES) //limit for #elements { InsertTailList(&DoubleHead,&psElement->linkfield); numberofentries = numberofentries + 1; } NdisReleaseSpinLock(&GlobalLock); } When I execute the code above, the computer crashes: DRIVER_CORRUPTED_EXPOOL, with an error in the marked line above. Any ideas why? Thanks Peter Tag: How do you tell WZC that our driver/adapter is WPA compliant Tag: 50144

    - FILE_DEVICE_DISK and VPB in a device filter Good people: I've a question about the toaster filter sample attaching to the disk stack. The filter calls IoCreateDevice specifying FILE_DISK_UNKNOWN on wxp since IoIsWdmVersionAvailable(1, 0x20) returns TRUE. Later in AddDeviceRoutine, the newly created device type was update with the lower's type which is FILE_DEVICE_DISK. I/O manager didn't create a VPB for the DO since it was FILE_DISK_UNKNOWN at the time it was created. Is there anything bad if the topmost device object is DEVICE_DISK but the VPB is NULL? It didn't crash on XP though. Thanks, Calvin - Calvin Guan Software Engineer ATI Technologies Inc. www.ati.com Tag: How do you tell WZC that our driver/adapter is WPA compliant Tag: 50142

    - Matching WM_DEVICECHANGE to a Device Object I would like to tie the WM_DEVICECHANGE message to a device object (DBT_DEVICEARRIVAL or DBT_DEVICEREMOVECOMPLETE). Is it possible to translate the dbcc_name received in the message to something that can be used in kernel mode to identify the device object? Or the reverse--is it possible for a WDM filter to get the dbcc_name given a device object? Just somehow need to bridge the message to the exact device.

    - how to stop network search for Microsoft Kernel Components? Hi, I'm deeply appreciated if anyone can provide clues on the following: I try to install an audio device through INF file in a system with fresh Windows XP. After the driver loaded, i could see a list of unknown devices in the device manager and it turns out that it is the OS tries to load up the Microsoft Kernel Components. However, it takes extremely long time just to load up each components. I notice that if the network cable is disconected, the loading time of those components takes only few seconds. It seems to me that the OS tries to scan through the network for the latest kernel components (correct me if I guess wrongly). 1. What is the bypass this network search process? 2. Can a device coinstaller affect it in any way? Thank you so much :) Tag: How do you tell WZC that our driver/adapter is WPA compliant Tag: 50129

    - DPC latency and ISR interruption resolved Sirs, thank to you all for your help and support, I'ver finally resolved the problem. In the end it resulted to be the kernel mode debugger which was interrupting the whole work to do his stuff. I've tested the driver on a fresh installation and it ran smoothly, after installing and enabling the debugger the problem reappeared. Anyway, I would like to thank you all for the effort and the ideas. Regards, and enjoy the weekend ernie Tag: How do you tell WZC that our driver/adapter is WPA compliant Tag: 50126

Unfortunately, that ain't enough. For XP, your driver needs to pass all of
the tests that WZC throws at you in order for it to know your driver is
worthy. These tests are defined in the 802.11 driver guidelines, which you
can get at:
