    - Intermediate Driver -vs- Filter Hook Driver First, thank you all for getting me started in the right direction. The links for info have been excellent. As I have begun to learn the technology and vocabulary I can now communicate somewhat better. I have pushed back to management that we do not need to develope a true vNic. The requirements are thus: Watch all network packets and redirect some of them to a different address. The the redirected packet will become a piece of data in a new stream of data sent by a socket to the different address. The "packet watcher" doesn't need to send the packet to a new address,it can call to "up" to an appliation layer to send it. Forgive me if this is not making sense, I am still getting the terms down. So, I think it can be done with: NDIS Intermediate Driver OR Filter Hook Driver Filter Hook Drivers seem to have the contsraint of only one hook. Some kind of entry point table for the hook and whover installs the address of their entry point gets the call. From my description, which do you think is the approach I should continue to research? Maybe there is an approach I have missed? Thank you for your help. Gil Tag: How to send a vendor command to usb audio driver from app? Tag: 34608

    - microsecond precision timing in VxD's and kernel drivers? Hi, I'm looking for a way to get reasonable 1-microsecond accurate timing in a VxD (9x/Me) on one hand, and in a kernel-mode driver (NT/2000/XP) on the other hand. What I need is a way to measure some delays inside the driver. I don't need to "schedule" anything. So it's just a measurement. Tag: How to send a vendor command to usb audio driver from app?

    - Device Manager icon --> custom icon? Hi all, I have my .INF file to install the registry keys for my new device class. Looking at the "Icon" string in other classes, it contains a value like -1 or -51 or -102 or 1401. The value is all over the map... of seemingly random rhyme/reason! Where do these Device Manager icons come from? Can I browse them all somewhere? (using "Change Icon..." in some system DLL file's Properties I assume) I don't know if they're from one file or individual DLLs specified by the EnumPropPages32 value. Right now the only way I can see to set my icon is by using the same one that another class uses. What I really want to know is: Can I create and specify my own custom Icon? Thanks for any help!

    - 64-bit driver install I am trying to figure out why pre-installing our USB driver works a little differently on a 32-bit WinXP than on a 64-bit WinXP. The only difference is that after the install on the 64-bit system, when the device is plugged in, instead of popping up the "Found New Hardware" wizard to allow the user to complete installation, the installation silently quits, and the user has to go back to Device Manager to ask it to install the driver. The pre-install of the .inf logged a warning about the INF not containing a digital signature(same on both systems). Yes, our driver is unsigned. The policy on the computer is "Warn". The only error I see in setupapi.log is 1168 "Element not found". But this shows in the successful installation anyway, so I am assuming it has something to do with our driver being unsigned. We have a 64-bit version of the driver, and the required NTia64 decorated sections in the .inf file. Our application and install program are 32-bit. We use SetupCopyOEMInf() to pre-install the .inf file. The DDK says "Provide both 32-bit and 64-bit compilations of all kernel-mode drivers, device installation applications, device installers, class installers, and co-installers. " Does it have something to do with our install program being 32-bit? We aren't using UpdateDriverForPlugAndPlayDevices, and I don't see any other specific instructions on what problems a 32-bit install would cause. Any suggestions would be appreciated. The driver itself works fine, we just have this one little installation glitch. Thanks, Diane Tag: How to send a vendor command to usb audio driver from app? Tag: 34566

    - Implementing JPEG support in unidriver based rendering plug-in Does ICM have to be handled by the driver in order for it to be recognized as one supporting JPEG compressed images? DDK is somewhat vague on the issue. Also it appears that for unidriver you should rather hook Escape instead of QueryDeviceSupport (it never gets called?). However, when application calls ExtEscape with QUERYESCSUPPORT and CHECKJPEGFORMAT parameters, it always returns 0, while rendering plug-in never gets called. (Though if you do QUERYESCSUPPORT for something else, it will call Escape of plug-in.) The flGraphicsCaps2 has GCAPS2_JPEGSRC bits set and both QueryDeviceSupport and Escape are hooked. Am I missing something? ICM? Tag: How to send a vendor command to usb audio driver from app? Tag: 34542

    - NDIS 5.0 intermediate driver problems with Nortel's VPN Hi, I am having some difficulties to operate my NDIS 5.0 intermediate driver in conjunction with Nortel's Contivity VPN Client. I start with a Dell laptop with an on-board 3Com NIC running Windows XP SP1. The laptop is plugged into a docking station with an additional identical NIC. I install the Nortel VPN Client software and reboot my machine. When the system comes up I install my software which includes an intermediate NDIS driver. The installation seems normal and no error messages are displayed. However, after I restart Windows, I cannot access the network (ipconfig only sees the VPN virtual NIC). The above problem has not been observed on any hardware except the Dell laptop, nor has it been observed on the same laptop when the installation is performed outside the docking station. Also, if I reverse the installation order (i.e. 1st my software, then Nortel's VPN), everything seems fine! Can anyone suggest what's going on? Any input will be most appreciated.

    - Q : About WPA of WLAN - How to generate AES key material? Q : About WPA of WLAN - How to generate AES key material? Hello, everyone. I am developing a WLAN Ndis driver for WPA and use WinXP Wireless Client program as a WPA configuration. Currently, I¡¯m testing "AES" encryption facilities at "Adhoc" mode configuration. I know 32 bytes of key material should be generated from SHA1 algorithm defined at Wi-Fi. (Shane noticed me that. Thank you very much Shane) But i couldn't understand the appendix F of Wi-Fi specification, April 2003. I need more information to generate AES key material. The details are: 1) In 802.11i D3.0, an HMAC-SHA1 Test vectors shows that sha1 has 20 byte output, but we need 32 bytes output for key material. I couldn't find any explanation about that. 2) I couldn't know that where "digest" came from as an input parameter when the first call to hmac_sha1. See below. hmac_sha1( digest, ssidlength+4, //Where from digest? Did it come from SSID value? (unsigned char *)password, (int)strlen(password), digest1); 3) What's the value of A_SHA_DIGEST_LEN when the 2nd call to hmac_sha1? Is it 32? Where was it defined or explained? See below. hmac_sha1( digest1, A_SHA_DIGEST_LEN, (unsigned char *)password, (int)strlen(password), digest); Thank you. Tag: How to send a vendor command to usb audio driver from app? Tag: 34536

    - Usb v1.1, Iso URB callback frame number is out of sequence I have written an Usb v1.1 Isochronous driver implementation. The attached Usb device uses the Philips Isp1581 chip. For the most part it works fine. I am resubmitting/recycling 2 Urbs. Each Urb has a buffer length to contain 4 frames worth of data. The Iso Max Packet size is 1020 bytes so the Urb buffer is 4080 bytes. The Urbs are passed back to my driver from the bus driver at intervals of 4 frames per Urb. All frames are in sequence. Occasionally, a Urb comes back at an interval of 8 frames (i.e. some frames have been skipped). Later, a subsequent Urb callback occurs containing the missing frames. In other words, this Urb has a frame number less then the previous Urb. When this occurs, The frame order is out of sequence and the data stream becomes non-contiguous. Does anyone have any idea how this can happen? Rex Tag: How to send a vendor command to usb audio driver from app? Tag: 34535

    - IoGetDeviceObjectPointer getting STATUS_SHARING_VIOLATION? I'm using IoGetDeviceObjectPointer to open \??\PhysicalDrive0.

    - MEDIATYPE_??? for grayscale images. I have googled heavily trying to find the appropriate mediatype and sub type for grayscale images. While I cannot find anything I would call definitive, I cannot believe that this has not been done before. Since there is no point in reinventing the wheel, I wonder if someone could point me in the right direction. The formats that need to be supported are: grayscale 8bpp, one byte per pixel grayscale 10bpp, two bytes per pixel, upper bits zero extended grayscale 12bpp, two bytes per pixel, upper bits zero extended (I can see the need for more bits in future cameras) I assume the major media type would be MEDIATYPE_Video. But the subtype?? I have seen a fourcc type Y800 (with apparent aliases Y8 and GRAY) that could work for the 8bbp. Should that idea be extended for 10 and 12 bits (Y010 and Y012 perhaps) or would another approach be better? MS seems to recommend creating new GUIDs which seems reasonable to me. I am hoping that there is a convention already in use (there must be a monochrome camera community out there using dshow right?) such that my device can fit in with any renderers that happen to support the existing formats.

    - How to find port resources used by hard drives? I need to find the i/o port and status port for each IDE hard drive connected to a system. So far I've been able to get these from the standard primary/secondary IDE controller by using the following method: 1. Open \??\PhysicalDriveX, where X is the drive number I'm intersted in. 2. Send it an IOCTL_SCSI_GET_ADDRESS 3. Open \Device\ScsiPortX, where X is the PortNumber returned by IOCTL_SCSI_GET_ADDRESS. 4. Send it IRP_MN_QUERY_DEVICE_RELATIONS with relation type of TargetDeviceRelation 5. Use IoGetDeviceProperty to send the DEVICE_OBJECT returned by #4 a DevicePropertyBootConfiguration query. 6. Walk through the CM_RESOURCE_LIST returned by #5 I can find the port resources for the drive. However, this doesn't work for a serial ATA drive for some reason. It works fine up to #5, but the IoGetDeviceProperty returns STATUS_OBJECT_NAME_NOT_FOUND (0xC0000034). So, is there a better way to get this information for each IDE drive? I've only been working with Windows device drivers for the past 3 weeks, so if anything doesn't sound right, it probably isn't. Let me know if I can provide more clarification to the question.

    - Replacing signed drivers Hello All, I have a doubt regarding one signed driver replacing another signed driver. My situation is as follows: [1] I have a set of drivers (version 1.0) which install a given USB device. These drivers were successfully WHQL tested. [2] Now i have a new set of drivers (version 2.0) for the same device. These drivers will also be tested with WHQL tool for certification. It can be noted that apart from driver versions there is nothing different between the 1.0 and 2.0 INF files. At this point i have a few scenarios which need clarification from experts: =========================================================================== 1) If user has installed version 1.0 drivers first and later tries to install 2.0 drivers (signed ofcourse) then will the 2.0 drivers replace the existing 1.0 drivers? 2) If user has installed version 2.0 drivers (signed) first and later tries to install 1.0 drivers, then when the device is connected which of the INFs will be considered for installation? 1.0 or 2.0? Is INF-matching based on newer of older versions of the INFs? NOTE: Installation in the above scenarios are done programatically through SetupXXXX functions. Any pointers on this will be highly appreciated. Hari Tag: How to send a vendor command to usb audio driver from app? Tag: 34507

I use win2k DDK to build the PORTIO sample in DDK successfully. But something is wrong when I use the gpdread and gpdwrite to test the driver. I use command line "GpdWrite -b 1 2" to write the number 2 to assigned 'base port address + 1', and then "GpdRead -b 1 "to read out. But the number read out is always 0xFF. I also tested writing a number every 1000 milliseconds and reading every 600 millisecond, but the read-out number kept 0xFF. what does the sample mean? could you tell me why? thanks Tag: How to send a vendor command to usb audio driver from app?

    - Receiving DBT_DEVNODES_CHANGED from a Windows service I have a Windows service that needs to be notified when a particular device has been enabled or disabled. When either of those actions happen, I have noticed that Windows broadcasts WM_DEVICECHANGE with a wParam of DBT_DEVNODES_CHANGED. Since services don't receive Windows messages, I understand that I should be using RegisterDeviceNotification along with HandlerEx to receive device notifications. However, the documentation for RegisterDeviceNotification says that it only supports the DBT_DEVICEARRIVAL and DBT_DEVICEREMOVECOMPLETE events, which doesn't help me. So my primary question is: How can my service be notified when a device has been disabled or enabled? Related questions: 1. I've heard that some people create a hidden window to receive broadcast messages in cases like this. This sounds kind of weird to me. What are the possible problems with this approach? 2. Also, can what I'm asking about be done from a Windows service with WMI? If so, is there any sample code of WMI being used for this purpose (in a service or otherwise)? Much thanks, -j Tag: How to send a vendor command to usb audio driver from app? Tag: 34490

    - How to use IOCTL_USBPRINT_VENDOR_GET_COMMAND and IOCTL_USBPRINT_VENDOR_SET_COMMAND Hello, I'm trying to use IOCTL_USBPRINT_VENDOR_GET_COMMAND and IOCTL_USBPRINT_VENDOR_SET_COMMAND to communicate with UsbMon(UsbPrint) in my language monitor but I have no idea how to set parametes of device io contorI that will be passed to portmonitor. I need to call GetPrinterDataFromPort of USBMon (portmonitor) inside GetPrinterDataFromPort of Language monitor to get/set some vendor specific data using IOCTL_USBPRINT_VENDOR_GET_COMMAND and IOCTL_USBPRINT_VENDOR_SET_COMMAND command. Are the following codes correct? In case of IOCTL_USBPRINT_VENDOR_GET_COMMAND, cbOutBuffer = 13; //3 1st:Vendor specific code, // 2nd:Vendor Request value - Most Significant Byte // 3rd:Vendor Request value - Lease Significant Byte //+10 size of data to receive lpOutBuffer[0] = VENDOR_SPECIFIC_CODE1; lpOutBuffer[1] = 0; lpOutBuffer[2] = 10; bRet = (*pIniPort->fn.pfnGetPrinterDataFromPort) (pIniPort->hPort, IOCTL_USBPRINT_VENDOR_GET_COMMAND, NULL, NULL, //pInput, 0, //cbInput, lpOutBuffer, cbOutBuffer, lpcbReturned); //...wait until this function finished... // Can I assume that lpOutBuffer[0] is the first byte of data after call above ? In case of IOCTL_USBPRINT_VENDOR_SET_COMMAND, cbOutBuffer = 13; //3 1st:Vendor specific code, // 2nd:Vendor Request value - Most Significant Byte // 3rd:Vendor Request value - Lease Significant Byte //+10 size of data to receive lpOutBuffer[0] = VENDOR_SPECIFIC_CODE2; lpOutBuffer[1] = 0; lpOutBuffer[2] = 10; lpOutBuffer[3] = 0x01; lpOutBuffer[4] = 0x02;....;lpOutBuffer[12] = 0x0A; //Set data here to sent. bRet = (*pIniPort->fn.pfnGetPrinterDataFromPort) (pIniPort->hPort, IOCTL_USBPRINT_VENDOR_SET_COMMAND, NULL, NULL, //pInput, 0, //cbInput, lpOutBuffer, cbOutBuffer, lpcbReturned); //...wait until this function finished... Because I have a situation that I can't verify, so I need to know correct implementation. Please give an advise for this. Thanks Jeth Tag: How to send a vendor command to usb audio driver from app?

    - New at this... need direction Hello, I have been assigned to write a device driver for 2000 & XP. I am a seasoned developer with an M.S. in C.S. I have zero experiece in writing device drivers. I have downloaded the DDK. Are there any web sites by MVP's that help? Is there a FAQ? Books? I was told that I have to have a development tool, that Visual Studio 6 will not do this. Is this correct? Help me get started so that I can understand the "vocabulary" of device drivers and better understand the posts in this news group and allow me to ask precise and informed questions. Thank you, Gil Tag: How to send a vendor command to usb audio driver from app? Tag: 34469

    - Example class installer for Win98 I've been tasked with writing a class installer for a Win98 driver. Unfortunately, there seems to be a conspiracy of silence on this subject. I have Googled until my mouse cramped. I have searched the Knowledge Base. I have searched the Technical Resources. I have read books (which have said there are no known samples and/or that the task is "hard" and will not be addressed). I simply cannot believe that there is not and never has been documentation on how to write a Windows 98 class installer DLL. After all, such installers do, in fact, exist! I would greatly appreciate any guidance that any of you may have on this topic. Feel free to email me directly, and I solemnly promise not to break the sacred layer of secrecy by telling anyone else of your help. Many thanks in advance. -- Roy M.

    - need help resolving crash cause hi all I have been working on a driver for winXP that emulates a harddisk, based on hardware that connects to the system through some General Purpose IO pins. therefore it is not PnP Enumerable and is "manually" root enumerated using IoReportDetectedDevice(). the DriverEntry and AddDevice routine load fine, and I can use it as the current drive in the CMD utility, read, write and copy from it, until it reports the following correspondence with the system: --------8<------------8<----------- CREATE/CLOSE function issued. major=IRP_MJ_CREATE, minor=0 RemoveLock acquired with tag 80F33330 Unrecognized IOCTL 4D0008h about to release RemoveLock with tag 80F33330 CREATE/CLOSE function issued. major=IRP_MJ_CLOSE, minor=0 CREATE/CLOSE function issued. major=IRP_MJ_CREATE, minor=0 RemoveLock acquired with tag 80F33330 Unrecognized IOCTL 4D0008h about to release RemoveLock with tag 80F33330 CREATE/CLOSE function issued. major=IRP_MJ_CLOSE, minor=0 CREATE/CLOSE function issued. major=IRP_MJ_CREATE, minor=0 RemoveLock acquired with tag 80F33330 Unrecognized IOCTL 4D0008h about to release RemoveLock with tag 80F33330 CREATE/CLOSE function issued. major=IRP_MJ_CLOSE, minor=0 ------------8<-----------8<-------------------- which is followed by the shutdown of all the harddrive- type drivers in the system. my driver is still operable until other services need the original harddrives and start crashing the system. what is the meaning of the above IOCTLs? I can't find this number in any .h file. it must be the result of some sinister #define. I tried to Install the checked version I downloaded from MSDN, but so far the installation either gets stuck in the file copying phaze or stops after not finding the license agreement file (I would appreciate help on this one also). thanks in advance, iddan Tag: How to send a vendor command to usb audio driver from app?

    - How to install genprint.dll?? Hi~, I'm newbie in ms-windows and VC programming. :) I should develop NT service program that prohibit user's printing any documents. I tested SetPrinter() and I found a problem. Using SetPrinter() can't control network printer that attached in other machine. ('Access denied' error is displayed when calling OpenPrinter() using DesiredAccess set to PRINTER_ALL_ACCESS) So I should find another method. I want to block all printers installed in local machine(local printer and network printer). But for the network shared printer, another computer should can print using this network shared printer. (Only a computer that my program is installed should be influenced by my program) Q.1 Can I hook printing event or job or print spooler? (I think GetJob() also can't filter user's printing job...) I posted this question to many newsgroups or forums but I didn't get suitable answer(may be impossible??...) Now, I'm testing Customized Print Processor using genprint.dll from ddk. I built and copy it to C:\WINNT\system32\spool\drivers\w32x86. And I made its installation program. int main() { ... nResult = GetPrintProcessorDirectory(...,processorPath,...); _tcscat(processorPath, _T("\\genprint.dll")); nResult = AddPrintProcessor( NULL, // server name NULL, // environment name processorPath,//processorPath, // path "My Processor" // ----> what string should I use?? ); } It returns error string("The specified module could not be found."). Q.2 Which string should I use in pPrintProcessorName field? and processorPath string(C:\WINNT\system32\spool\drivers\w32x86\genprint.dll) is right? Q.3 If I success AddPrintProcessor(), how can I change Print Processor to "My Processor" from "WinPrint" of existing printer? Q.4 I can't change Print Processor property of network printer manually(Print Processor button is disabled). That means, using customized print processor also can't control printing network printer? Thanks in advance. And I hope you can understand my poor english :) Tag: How to send a vendor command to usb audio driver from app? Tag: 34450

    - PCI sample driver for 2K Hi, Is there any place where I can find a sample PCI device driver for Windows 2000. Or can anybody mail me the skeletal driver of the PCI driver. I am a newbie and have to write a device driver for a PCI based device on win 2k. Can anyone tell me if it is possible to have 2 drivers loaded for the same device? One more question... Can a user application directly talk to this PCI device without any device driver in between? Somebody was saying something about IOCTLs... Is that the right lead? Please help!

    - handling multiple interrupts?? hello sir, am working on developing wdm driver for a cpci carrier board.four independent I/O modules can be mounted on a carrier.so in a memory map there are four seperate memory space for each i/o module. usually in a application i call createevent & send it to driver inturn driver calls ObReferenceObjectByHandle - Registers Event in kernal mode. on interrupt driver calls KeSetEvent to notify the app the event. there is a single driver & four different applications comunicating with driver. now the question is how do i handle interrupts?? should each application call create event & send to driver? & how driver notify the different applications correctly when multiple interrupts are generated?? how to hold each application handle & notify to it?
