    - Setting WPA key by OID_802_11_xxx Hello, I am trying to set WPA key using OID_802_11_xx OIDs. I set following OIDs in order OID_802_11_INFRASTRUCTURE_MODE to Ndis802_11Infrastructure OID_802_11_AUTHENTICATION_MODE to Ndis802_11AuthModeWPAPSK OID_802_11_WEP_STATUS to Ndis802_11Encryption2Enabled OID_802_11_ADD_KEY using output of PBKDF2("KT12345678",ssid,ssidlength,4096,256) algorithm (to get 256 bits key from "KT12345678" preshared ASCII key ) OID_802_11_SSID using ssid But there is something wrong with EAPOL 4-way handshake communication. AP stays in authentication phase so I can not get IP address from DHCP server. Do I use wrong key algorithm or my order of OIDs is not correct? I saw that people are sending two OID_802_11_ADD_KEY OIDs after OID_802_11_SSID OID and it works. Could someone tell me at which moment these two OIDs are sent and what is used as WPA key (preshared or output of PBKDF2 algorithm)? I do not understand who is responsible for WPA authentication, client software or wireless driver. If I send WEP key to wireless driver everything is Ok (driver takes key, authentication process is done by driver and I get IP address from AP) but with WPA it is not case.

    - Custom DeviceIoControl Handling in Stream Minidrive ? (shared memory user - kernel) Hi, I have the screnario as below : I need to have custom IoControl code to communicated with user-mode application, I know how to to it in non-minidriver kernel mode, but how about in stream minidriver ? On kernel streaming driver code: DriverEntry(IN PDRIVER_OBJECT DriverObject, IN PUNICODE RegisteryPath) { DriverObject->MajorFunction[IRP_MJ_DEVICE_CONTROL] = <ouriocontrolhandler> ... ... } Then we have a function: NTSTATUS OurIOControlHandler(IN PDEVICE_OBJECT DeviceObject, IN PIRP Irp) { irp = IoGetCurrentIrpStackLocation(Irp); controlCode = irpStack->Parameters.DeviceIoControl.UoControlCode; switch (controlCode) { .... <do our work here> } } However, on stream minidrive, DriverEntry( IN PDRIVER_OBJECT DriverObject, IN PUNICODE_STRING RegistryPath ) { HW_INITIALIZATION_DATA HwInitData; HwInitData.HwReceivePacket = MyReceivePacket; HwInitData.HwCancelPacket = MyCancelPacket; HwInitData.HwRequestTimeoutHandler = MyTimeoutPacket; <continue> ReturnValue = StreamClassRegisterAdapter(DriverObject, RegistryPath, &HwInitData); } So can I l put in the line (or is it safe to do so ?, will it be overwritted) : DriverObject->MajorFunction[IRP_MJ_DEVICE_CONTROL] = <ouriocontrolhandler> in stream minidriver ? what <StreamClassRegisterAdapter()> put in for this parameter (IRP_MJ_DEVICE_CONTROL) ? will it overwrite my parameters ? If I want to have my custom IoControl In minidriver, what is the proper way ? Note: Ref: TestCap DDK sample Thank in advance WP Tag: DrvFillPath Tag: 48697

    - passthu problem again. hi, a few days ago i posted a query regarding pasthru IM driver not transmittng larger packets. Mr. Thomas Devine pointed out the article at the following link : http://www.ndis.com/pcakb/KB05280101.htm, but even when i return NDIS_STATUS_NOT_SUPPORTED for OID_TCP_TASK_OFFLOAD in the MPQueryInformation() , the problem persists. any more suggestions ? i have a hunch that this has got something to do with MTU. when i access larger files across the network, the passthru sends the packets of the size of MTU and when i append my own headers, the size gets larger than the MTU and ultimately results in the rejection of the packet. can anybody tell me how i can make the top level network driver to send the packets with size a little less than the MTU so that i can accomodate my headers without exceeding the MTU for NIC ?? thanks in advance. regards.

    - Video streaming USB device driver based on USBCAMD and AVstream ar Hi, Im trying to develop a driver for USB2.0 camera. I was going through the Microsoft DDK site and it mentions that future driver development must be done with the Windows Server 2003 DDK. So, I have installed this DDK and on going through the samples have come across a driver for an Intel USB Camera. This sample is located in the "...\WINDDK\3790\src\wdm\videocap\usbintel\sys". folder. On going through this example I find that it is based on USBCAMD and on the "stream class" architecture. The "USBCAMD" is fine, but the "stream class architecture" is not. The DDK documentation states that the "stream class architecture" should no longer be used, though it is still provided. The document states that new video drivers must follow the "AVstream architecture". So, I was wondering if there's any way I could get a similar sample driver code for a Video streaming USB device based on USBCAMD and the AVstream class architecture. Please suggest. Thank you, Ravi.

    - request for info Hi, I'm hoping to find some help from you device experts. I need to find a way to catch events from a bar code scanner that is confiured as a keyboard wedge. It shows up in my device manager as a HID and I can open it using the HID functions. However, since it's a keyboard device I can't get read or write access (it's already locked by the OS). Can I still get notifications of events from this device after opening it (CreateFile) without read/write permissions? If so, please give me a hint. thanks very much, Deanna Tag: DrvFillPath Tag: 48677

    - Re: Power Management in PASSTHRU Thanks Maxim. I think I found the thread you're referring to. There certainly was good information there. I now know, among other things, that MPHalt can be called without PtUnbind ever being called. Unfortunately, however, it didn't address my issue. I believe my question boils down to this: 1. Does NDIS serialize PNP events with respect to send/receive paths? 2. If not, is it a requirement that a packet does not leave the driver from an edge that is in low power? If the answers are 1)no and 2)yes, as I suspect they are, then I believe we have a bug in the PASSTHRU driver. As always, I am very grateful for any insight anybody may have on this.

    - NDIS Prism2 I am looking to add some functionality to an 802.11 card so that I may put it into some of the test modes that the firmware supports but windows doesn't. what do I need to do/where should i look to get example prism2 chipset NDIS miniport code. I feel like it should only be a minor addition to the driver to make it work, but I don't want to have to write the driver over from scratch. any thoughts/help would be greatly appreciated. thanks, brad Tag: DrvFillPath Tag: 48625

    - dumping packet contents from USB driver for debugging Hi, In my usb driver , i have ot communicate isochronous data to a USB device . Before calling the IOCallDriver for the lower level Windows provided drivers , i make the requiest packets , and fill the usual structs etc including Urb.UrbIsochronousTransfer.IsoPacket[]'s length and offset parameters , but the memory they are using is in an MDL structure . Is there a way to dump the content of each packet in the IsoPAcket array , into a debugger? Can this be done by enabling the tracing level of any lower level windows USB driver stack component? can and should this be done is my USB driver? regards Taha Tag: DrvFillPath Tag: 48610

I renamed them to unidrv.dll,unidrvui.dll. Now I went to the XP ddk and built the koemuni.dll. I tweaked up the oemdll.inf in the \oemdll directory of the XP ddk to point to the koemuni.dll instead of oemuni.dll. Now I do the Add printer steps and finally it lands with a failure dialogbox on windows 2000 saying:- --------------------------- Add Printer Wizard --------------------------- Printer driver was not installed. Operation could not be completed. --------------------------- OK --------------------------- "D:\WINDDK\2600\src\print\oemdll\oemdll.htm" says:- "However, the Windows NT® 4.0 printer driver files will either need to be copied to the local directory containing Oemdll.inf, or during installation, you will need to point to the location where these files may be found. For the kernel-mode samples to work, the kernel-mode drivers (the Windows NT 4.0 drivers) used most support COM OEM Printer Customization DLL extensions, while the driver files in Windows NT 4.0 Service Pack 4 and earlier do not." I do this on a windows 2000 machine.Am I using a wrong version of unidrv4.dll and uni4ui.dll,etc. thanks vipin Tag: DrvFillPath Tag: 48583

    - how apc work? I've read that after kernel has queued apc in destination thread it request software interrupt at apc level. All threads execute at irql<=1 so how is it made?. Is it that nothing happens with apc queued calls until irql drops below 1(to 0) to start apc interrupt and than we are in some thread. What will happen if apc is in other thread. Is kernel checking all threads in system for threads with apc and executing them and after processing all apc releases interrupt or how it works? Tag: DrvFillPath Tag: 48581

    - printer driver -> font much too small Hi In the DrvTextOut function of my virtual pritner driver I'd like to calculate the font size (in device units) that I have to pass to the CreateFont function to replay the recorded print job. Now... how do I calculate this? like this: IFIMETRICS *ifFnt = FONTOBJ_pifi(pfo); XFORMOBJ *xFrmObj = FONTOBJ_pxoGetXform(pfo); XFORML xFrm; XFORMOBJ_iGetXform(xFrmObj, &xFrm); float eXScale = sqrt(xFrm.eM11 * xFrm.eM11 + xFrm.eM12 * xFrm.eM12); float eYScale = sqrt(xFrm.eM22 * xFrm.eM22 + xFrm.eM21 * xFrm.eM21); int SizeInDeviceUnits = (int)(0.5 + (eYScale * ifFnt->fwdUnitsPerEm)); well, this code is not invented by me... I got it from http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q264243 ok, they calculate the point font size... so the Size they calculate is iTmp = (int)(0.5 + eYScale * fwdUnitsPerEm * 72) / sizLogResPpi; Now the problem: The calculatet font size is about 10% too small. ... can someone explain me why? I mean, 10% is not nothing... could this have to do with the resolution of my device? ... any ideas how to find out what's wrong here? thanks a lot MR Tag: DrvFillPath Tag: 48578

    - PnP test tool report registry error even though it runs fine The driver is for a special disk controller. It is witten based on a floppy disk controller model and runs fine. But after running the test using the PnP test tool provided with the WinXP DDK, it does not work any more. Test result in PnP test tool shows under PROBLEM INFORMATION: case CM_PROB_REGISTRY. Under device manager, the device show in General TAB: "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged (Code 19)" According to the doc in the DDK, the cause to this is said: "This error message occurs when a device has more than once service defined, if there is a problem opening the Service key, or if you cannot locate the driver name from the Service key" I looked in the registry, and found only one ImagePath for this device And the path is correct.

    - ISR problem with my own com-port FDO-driver hello, i'm currently working on a simple fdo-driver to replace serial.sys on my win2k machine. the driver only has to read/write over COM-port, but needs a special isr. the serial-source from the ddk is very complex and does not properly build, so i thought to make my own serial-driver. the main problem is: within the function to handle the pnp-irp IRP_MN_START_DEVICE i want to connect my isr. it seems to work (the debug-msg tells me so). but i can't notice any call of this isr. so far the driver can read/write over the com-port, but only on IRP_MJ_READ/_WRITE. now i need an isr to read when data is available. i set the appropriate register values (interrupt enable = 0x01) but nothing happens when uart receives a byte. what am i doing wrong? i would be very happy about any suggestions, because i couldn't crack this prob for nearly a week :( thanks here my code of the interrupt connection: ========================================================================================= NTSTATUS HandleStartDevice( IN PDEVICE_OBJECT pDO, IN PIRP pIrp ) { USHORT IntMode; ...

Hi

When Windows calls my DrvFillPath function of my printer driver, it passes
(sometimes) more than 6000 subpaths (MoveEx, Polyline, Polyline,
CloseFigure).... so my question now: Where does this come from? Just from
one command? Or did the creating application call the FillPath fuction
several times? ... 6000 times? Or how's this handled? So, when I'd like to
write a test application that creates me that many subpaths and just one
DrvFillPath call... what do I have to do?

thanks

ok... it was a bug in my driver...
it only gets 57 points, but because of a bug the driver reads it about 2000
times... I don't understand why it doesn't crash... but anyway...
