    - SilentInstall Hi We have developped a device driver stack that "mounts" removable storage. When a new volume is detected by PnP manager, the system ask for one of our drivers (the one actually creating the disk objects), even is this driver has already been installed in the system. We have then to provide the path to this driver file, and this is somewhat annoying. We want to avoid this behavior. In our DispatchPnp routines, we set the SilentInstall capabilities this way: case IRP_MN_QUERY_CAPABILITIES: { PDEVICE_CAPABILITIES capabilities; capabilities = irpSp->Parameters.DeviceCapabilities.Capabilities; capabilities->SilentInstall = 1; ... ntStatus = STATUS_SUCCESS; break; } Our drivers are not digitally signed and won't be for a long time. What can be done to avoid that the system asks for the driver file, that has actually already been installed ? TIA VV Tag: Wlan drivers Tag: 47264

    - powrprof.h missing in 2003 ddk I need to call power management API "CallNtPowerInformation" in my function. The function is defined in powrprof.h, but I cannot locate the file under win2003 ddk include files. How am I to use that? But I do find that powrprof.lib is still available under 2003ddk, but header file is missing. thanks Tag: Wlan drivers Tag: 47263

    - WHQL: can Microsoft sign the filter driver? Can Microsoft sign the filter driver + its class coinstaller DLL for the CD/DVD-ROM stack, which inserts itself between IMAPI and the storage port? The class coinstaller is needed with the sole purpose of patching the LowerFilters value for the newly arrived hot-plug (SBP-2 or USB) drives, and injecting our filter below IMAPI, so that IMAPI's SCSI traffic will also be monitored. -- Maxim Shatskih, Windows DDK MVP StorageCraft Corporation maxim@storagecraft.com http://www.storagecraft.com Tag: Wlan drivers Tag: 47231

    - Writing kernel API functions Can anyone direct me to documentation on how to write, or whether it is feasible to consider writing, a kernel API function that permits a kenerl component, such as a device or filter driver, to initiate communication with a user-space service? I have a need to develop something like the Event Log API that is available for device drivers or the WMI interface. I know that these actually communicate with other kernel code, but I would really like to send information to a service, without requiring that the service issuing an IOCTL to the driver and waiting for a response. -ken Tag: Wlan drivers Tag: 47221

    - printer driver signing Hello, Does driver signing requires the driver to be associated with hardware device. For e.g:- If I have a printer driver which acts as a format convertor(lets say converts to .doc format), how can I get this driver signed? I feel it is possible to have computer policies which restrict installation of drivers which aren't digitally signed. So I would prefer to get them signed. Any insights here with the above case. This is for windows 2000/XP/2003. thanks vipin Tag: Wlan drivers Tag: 47220

    - decrypt WPA group key Hi, This probably isn't the best newsgroup for this question, but probably the ones knowing the answer can be found here :) During WPA group key handshake using TKIP I will recieve a key encrypted with RC4 I have used OpenSSL to decrypt and that works fine, but I would like to use CryptoAPI. This is how I have done it with OpenSSL void DecryptGTK(unsigned char *pIV, unsigned char *pKEK, unsigned char *pData, unsigned char *pRet) { unsigned char keys[32]; memcpy(keys, pIV, 16); memcpy(&keys[16], pKEK, 16); RC4_KEY key; RC4_set_key(&key,32, (const unsigned char *)&keys); unsigned char tempin[256]; /* Temporary input (discard) */ unsigned char tempout[256]; /* Temporary output (discard) */ RC4(&key, 256, tempin, tempout); /* Step 256 times */ RC4(&key,32,pData,pRet); } now I started to implement the CryptoAPI, but right now I can't make sense out of it. DWORD dwCryptoPasswordLength; DWORD dwDataValueLength; HKEY hKeyResult; HCRYPTPROV hCryptoProvider; HCRYPTKEY hCryptoKey; HCRYPTHASH hHash; if(!CryptAcquireContext( &hCryptoProvider, NULL, NULL, PROV_RSA_FULL, 0)) { printf("!CryptAcquireContext"); } if(!CryptCreateHash(hCryptoProvider, CALG_MD5, 0, 0, &hHash)) { printf("!CryptCreateHash"); } dwCryptoPasswordLength = 16; if(!CryptHashData(hHash, (LPBYTE)pKEK, dwCryptoPasswordLength, 0)) { printf("!CryptHashData"); } if(!CryptDeriveKey(hCryptoProvider, CALG_RC4, hHash, CRYPT_EXPORTABLE, &hCryptoKey)) { printf("!CryptDeriveKey"); } if(!CryptSetKeyParam(hCryptoKey, KP_IV, pIV, 0)) { printf("\nCryptSetKeyParam\n"); } dwDataValueLength = 32; DWORD dwBuff = 32; if(!CryptDecrypt(hCryptoKey, 0, TRUE, 0, pData, &dwDataValueLength)) { printf("!CryptDecrypt"); } any ideas how this should actually be solved? /thanks Tag: Wlan drivers Tag: 47219

    - Terminal server and windows 2000 Printer driver Hello, Can someone explain me this behaviour:- 1) Installed my printer driver on machine A locally on 2000 terminal server. 2) Connect to machine A from a 2000 professional machine "vipin" using remote desktop connection and login as USER1(this is in administrative groups) 3) Connect again to machine A from 2000 professional machine but with login USER2(Administrative group rights) Observation:- Each time I connect, I see a new printer getting created of the form printername\vipin\session0 printername\vipin\session1 .... and makes it the default for the session. Everytime I logoff the session, the correspomnding session instance gets deleted. It would have been fine if there were one session instance viewable in the session's printer folder, printer session instances of all the sessions to the Terminal server are visible. In addition there is a printer of the form "printername". These are viewable also when you log as a user on the Terminal server itself. So I installed the Microsoft drivers(one's that come with the operating system using Add Printer), I make connections, I don't see the behaviour. Can someone tell me whats causing this behaviour? thanks vipin Tag: Wlan drivers Tag: 47210

    - "The file or directory is corrupted and unreadable" during installation of a PnP printer device. Hi All, I have a strange problem with a Printer INF file that I don't know how to resolve... I have created an INF file through MS genINF tool. The printers included in the INF file support serial, parallel (IEEE 1284) and USB interfaces and as you may suppose the parallel and USB interfaces support PnP. The file in my opinion is a correct one and when I install the driver without "Automatic Windows detection wizard" but with manually choosing the Printer port and driver location all the things work fine. The installation wizard copies the driver files successfully to windows driver directory. However during the driver installation for automatically discovered PnP printer (for example with USB interface) when I choose "Specify a location" in "Locate Driver Files" dialog page and after that "Next" Windows locate my INF file as a correct driver INF file but when I press "Next" button the following message appears in the next dialog page: "An error occurred during the installation of the device. The file or directory is corrupted and unreadable.". I have tried the mentioned procedure on 3 different machines and always get the same result (Windows 2000 SP4). That is why I suppose that the problem is not with the directory but with the INF file. Can someone help with this ? 10x in advance! ___________________________________________ Best regards, Ivan Dimitrov Tag: Wlan drivers Tag: 47201

    - Help! layered drivers lead to Blue Screen Dear All, I develop a layered driver for a usb token including 3 part. Enum.sys -> VR.sys -> key.sys Enum.sys is a enumerator to enum key, VR.sys is the driver for virtual smart card reader and key.sys is the driver for the key. Now, I meet a problem, I write a PC/SC application to send APDU sequentially to my token, but some time when I surprisedly remove the token, the system will crash and show there is a 0x000000ce fatal system error in VR.sys. That means there is an operation not cancel in VR.sys when key.sys unload. I think may be when the token removed, the VR will delay to get the message and the application still send IRP to VR.sys, so it will cause system crash. Is that right? And who can help me to get the solution to this problem. Thank you very much! Best Regards! Tag: Wlan drivers Tag: 47196

    - Multiport Serial I am writing a kernel mode driver for a PCI card with 16 serial ports. It is a WDM style driver, and in my INF file I've made the class "Multiport Serial" (GUID 50906cb8-ba12-11d1-bf5d-0000f805f530). The driver archetecure is based on the multifunction example in Walter Oney's 2nd edition WDM book. In the AddDevice routine for the child part of the driver, I'm calling IoRegisterDeviceInterface, using the GUID that the serial driver uses for the same call (86e0d1e0-8089-11d0-9ce408003e301f73). None of the 16 child devices seem to appear to the system as serial ports. Hyperterminal does not recognize them. Although the Device Manager shows a Multiport Serial entry, with the 16 devices (and the controller/parent device, which I really don't want users to see), it does not list them under Serial Ports. What exactly does "Multi Port Serial" mean to Microsoft? If not RS232 type serial, then what was the intention? Does anyone have any ideas on how I can let the system know that my devices are serial devices? Tag: Wlan drivers Tag: 47189

    - I need help... with large project that I have worked on for many years described below. I am looking for help in any form. The projects hopefully should begin to produce some cash flow not too far in the future. Unfortunately because I am the only developer and the project is very large, releases are occurring dreadfully slow. I think there may be compatibility between your knowledge and experience and mine. I would like to set up a private access CVS directory. I have the server and a copy of CVSNT and have already installed it. But I have no experience with getting things setup. If you would like to help please reply to infoz@edenspeace.com. Also I'm kind of burned out so I'm not able to do anything really challenging at the moment. Description of the project below. Thanks, Tim ------------------ The immediate problem: At www.reago.com click on MouseHead. I have a user mode continuous AV recorder however as soon as I stress the system with the audio/video comprehension, wdmaud and video are locking up in terminal loops inside of the kernel drivers. I may need to move down to a kernel mode driver. ------------------ The larger project: A collaborative project for generalize data comprehension and responsive feedback is forming from work I have done over the past 10 to 15 years; resulting in part in a signal processing data abstraction engine. The goal is to provide human-like interactive conversational access to a distributed human knowledge network. And on local machines, instead of reading books, to provide a conversational interface. Florida Institute of Technology is interested Virginia Tech Human Interface Lab is interested TC Williams, a tech savvy high school is interested A pipeline of software releases has begun at mi web site http://www.reago.com leading up to ai-Books and ai-Mentor. The first release is a web cam controlled mouse, MouseHead. The business plan is simple. Give away the products and ask for donations. If necessary, charge for spin-off services and products. These products represent an enormous effort on mi part. Substantial innovative technology. How to grow beyond a one man project is the challenge. International University associations seem likely to be one of the best solutions. To date outside of the US the following countries have produced the most hits on the web site, in this order: Belgium, Switzerland, Australia, Hungary, Netherlands, Brazil, Germany, South Africa, Poland, Italy, Lithuania, Israel, Sweden, Norway, Argentina, plus about 50 more countries. I have contacted professors at two of the universities in Switzerland with related high-tech development departments and I will contact compatible universities in these other countries from the top of this list to extend the collaboration. Hopefully gathering together a developer or two from each university. Two private access discussion forums are set up at www.edenspeace.com/groups. ai-Books for development and NSP for architecture. More will be added as needed. Thousands of pages of existing source code were developed using Borland C++ Builder v5. I am presently considering a switch to the following cross-platform open source building blocks for the visualization and maintenance interface: OpenGL, foundation 3D libraries OpenSceneGraph, 3D scene visualization and construction OpenProducer, 3D camera control BlueMarbleViewer, large scale data paging and region zoom wxWidgets and wxGLCanvas, OpenGL compatible O/S windows wrapper GCC compiler OpenThreads, cross-platform multi-threading interface Features extracted from CVS version control for multi-developer support Also: Custom server and network visualization and maintenance environment Custom applications and server layers The NSP core network architecture recently finished a full review by a uspto primary examiner, no conflicts found. Specifically with reference to AT&T research labs one of the problems yet solved is the visualization and editing of massive continuously evolving data networks, including real-time changes, and probably best displayed in 3D. Formerly I handled this on a 2D flow-graph basis which is insufficient for the large volumes of data associated with the neural comprehension engine. Does AT&T have any interest in this project? Having read the various project you all are working on, I know there is compatibility. Specifically with reference to OSR one of the problems yet solved is industrial strength continuous audio/video recording. Thus far audio/video recording in user mode is not working too well, having tried as many combinations of possibilities as I can imagine. The project presently has zero budget.

    - Passthru problems at Distpatch_Level Hi, I am using the NDIS IM Passthru driver. I have to redirect the packets to another (Target) driver for processing. I did it by sending IRPs from MPSend and PtReceive functions. User mode applications will also be accessing that Target driver. I used Mutexes to enforce mutual exclusion in access to resources in that driver. However I soon got Bug Checks and Page Faults. The reason was that MPSend often was called at DISPATCH_LEVEL and waiting for mutex at IRQL=2 caused those errors. The question is why MPSend is called at DISPATCH_LEVEL ? Is there any way to avoid it ? If not, can I wait (for the mutex) at DISPATCH_LEVEL ? (I searched the internet and have concluded that I cannot ). If also not, what should the ioctl handler of the Target Driver do if it gets the IRP containing the packet from MPSend and the mutex is not available. I cannot queue the IRP and return status_pending because that would also mean waiting in MPSend at Dispatch_Level ? any help from anybody would be appreciated. thank you. Tag: Wlan drivers Tag: 47125

    - Winsock internals... Hi, Take in mind the following scenario: two computers are sending data to each other ( using winsock ), one computer send data faster then the rate data is being processed by the other computer, this will cause the target computer TCP Stack to get filled and the source computer will not be able to send data until the target computer will handle this data, Taking that in mind, what happen in the period of time the source computer try to send data to the full TCP Stack of the target computer? does the data is being re-sent over the net in each try? how does this functionality is implemented by winsock? what happen in this period of time? what data is sent over the net at each re-try???

    - ask expert of PCSC driver one question dear all: I have finished one driver of usb device that comply with PCSC spec.The driver can work correctly.I use the usbverify to test my driver and device.I found I could not transfer the data to the device after I install the usbverify on my device. I can not alansys the problem with windbg.And if I insert my device into the USB 2.0 hub connected to the NEC PCI to USB CARD .The windbg will report that usbehci.sys +237a has one error.I doubt whether the PCSC affect the transfer. I found the struct of _SCARD_READER_CAPABILITIES in DDK.Does the member in _SCARD_READER_CAPABILITIES affect the transfer? Note : usbverify is the test tool provided by DDK .It can test usb device. Thanks a lot! Tag: Wlan drivers Tag: 47091

    - ISA Interface Card DDK experts, We are porting Device Control software from MSDOS to Windows 98 and need to write a Device Driver for a legacy ISA Interface Card. I built the sample Device Driver for an ISA Card in chapter 7 of "Programming the Microsoft Windows Driver Model" by Walter Oney with Visual C++ 5.0 and the Windows 98 DDK (Driver Development Kit). We are now entering the testing stage and I was wondering how to specify what ISA bus is being used by the Interface Card. Maybe in the LogConfig section of the INF file ? The Device Driver seems to install OK whether the Interface Card is plugged in or not since this Interface Card is not "Plug and Play". Stephen Tag: Wlan drivers Tag: 47080

    - What registry key to delete to reinstall a device Dear developers, I am a newbie in device driver programming and installation. I am developing device driver for my usb device. The first time my device re-enumerated with PC, the PC will ask for .inf file for driver installation. Now I want to update the driver and have I written a new .inf file for the device installation, but the problem is, PC never ask for another .inf file anymore. I understand the installation information from the first installation had been saved to registry. Now I just want to make my PC fresh just like it's never been installed the old usb driver. How can I do that? What registry entry should I delete? Please help. I tried to delete registry key: \HKLM\SYSTEM\CurrentControlSet\Enum\USB\Vid_xxxx&Pid_xxxx but regedit won't allow it.

    - Convert serial port to TCP/IP and back again I am trying to write a windows 2000 driver that co-operates with an application on another Posix compliant system (QNX). Posix app gathers data from a serial port and transmits it via TCP/IP. The function of the windows 2000 driver will be to take this data and reconstruct it and present it as though it were coming from a local serial port. The first thing I would like to know is ... am I trying to re-invent the wheel here? I mean is there some existing driver I could use for this purpose? Is this a potentially large and difficult task or is there some fairly easy way to approach the problem? How would you approach it? Tag: Wlan drivers Tag: 47074

    - Having Problems With PsGetVersion when TARGETTYPE=MINIPORT. I get link error 2019 and PsGetVersion is not recognized. If I change to TARGETTYPE=DRIVER everything is ok. The problem is that I am dealing with a tape driver so I believe it needs to be MINIPORT. Is there anyway to get around this situation. Thanks! Tag: Wlan drivers Tag: 47070

    - Logging FastIO File Accesses How should I go about logging FastIO file access. I basically want to log every file (full path) that is accessed on a system. Currently IRP requests are logged fine. At which stage can I query the file system for the filename of a FastIO request? Thanks Tag: Wlan drivers Tag: 47062

    - NAT implementation in an IM driver Hi all, To implement NAT in an IM driver, besides translating IP, ports, adjusting checksums, a new Ethernet header needs to be constucted. Getting the new source MAC address (from one of the miniports below) is not a complicated task. But how to get the destination MAC address? Should the above protocols (ex. TCP) be involved in the process of getting this MAC address? Valeriu Tag: Wlan drivers Tag: 47058

    - compiler switches, #defines I'm using the USER_C_FLAGS in my sources file to create a #define for my source files as in USER_C_FLAGS = /_DRIVER_ here is a dab of the my code #ifdef _DRIVER_ ldkfsl dkfs; #else sldkfj slkdfjs; #endif now you might think I'd end up with an error from one of these lines as this code is compiled, but I'd never expect my output to look like this: e:\filearch\abc.h(2): error C2061: syntax error : identifier 'dkfs' e:\filearch\abc.h(2): error C2059: syntax error : ';' e:\filearch\abc.h(4): error C2061: syntax error : identifier 'slkdfjs' e:\filearch\abc.h(4): error C2059: syntax error : ';' seems the compiler is happy exploring both paths?
