    - Does the vender can disable any property page of the printer?? Hello all, There are many property pages in the printer, like the "General", "Sharing", "Ports", "Advanced", and "Color Managment". Can I disable one of them (Ex: disable "Advance" page), or to disable all the radio buttons of one page(Ex: disable all the radio buttons of "Advance" page)? Thanks.

    - 1394 Isoch on Windows 2000 I have developed 1394 driver similar to 1394diag. Isoch operations(no special requirements like TAG or SYNC) works almost. But very few times, I observe the buffers are not transmitted even if they are attached. I see it on analyzer. I stop Isoch and start it. Still Isoch wont transmit. No error in allocating Isoch buffer resources, no error in attaching buffers but simply my Isoch completion callback never called. Attached buffer callback is called and no error is reported. I dont understand what is causing the problem. No error is returned for attach buffers. Finally I found a work around, not really useful :( Unplug the cable and plug again. Allocate Isoch buffer resources and attach buffers and Isoch talk. It works now. So unplugging and plugging is causing something to reset and Isoch transmit works. I am not undertstanding circumstance that causes this problem. But I observe very few times. If I initiate bus reset through software command, no use. Only unplugging and plugging device will help. I have temptation to blame microsoft 1394 bus driver because after attaching the buffer, it is bus driver that transmits the Isoch data. But I couldn't find out the circumstances clearly that are causing the problem nor the way to debug. Any gliches in Isoch operations after every bus reset?

    - ksproxy INF File Basic Question I have been studying the INF file associated with one of the usbcamd2 examples (the USBINTEL.INF) and creating a commented version such that I can grasp all the details. One bit that is not quite clear yet involves the interfaces. Living as I do in the past and being most comfortable with device objects/symbolic links rather than device interfaces, it took me a while realize what the [.Interfaces] section was actually doing. Now that I realize that AddInterface registers the interface(s) supported by the KM driver (as opposed to, for example a COM interface which gets registered in other ways), I am a bit unclear on what is happening in the subsequent AddReg section. The relevant parts of the INF file are: [Intel.USBDCam.Interfaces] AddInterface=%KSCATEGORY_CAPTURE%,GLOBAL,Intel.USBDCam.Interface AddInterface=%KSCATEGORY_VIDEO%,GLOBAL,Intel.USBDCam.Interface [Intel.USBDCam.Interface] AddReg=Intel.USBDCam.Intf.AddReg [Intel.USBDCam.Intf.AddReg] HKR,,CLSID,,%ProxyVCap.CLSID% HKR,,FriendlyName,,%USB\VID_05D0&PID_FFF4.DeviceDesc% HKR,PageAliases,"{71F96464-78F3-11d0-A18C-00A0C9118956}",1,21,E8,C2,3D, 13,47, d2,11, 0xba, 0x41, 0x0, 0xa0, 0xc9, 0xd, 0x2b, 0x5 HKR,PinFactory\1\Interfaces\{5BB95400-52BB-11d2-BA41-00A0C90D2B05},,, Now for the questions: 1) A question about interfaces. It is now my understanding that, in general, the registry entries specified in [Intel.USBDCam.Intf.AddReg] only have meaning in the context of the interface, for example KSCATEGORY_CAPTURE. In the context of some other interface, for example MY_CUSTOM_INTERFACE, there could be some completely different set of registry settings that could be used as needed. Thus, the fact that KSCATEGORY_CAPTURE and KSCATEGORY_VIDEO can be registered with the same AddReg section indicates that the implementors of those two interfaces chose to require the same registry settings. It does not indicate anything profound about interfaces in general. Is this correct? 2) Regardless of the answer to 1, what is the meaning of the listed entries? CLSID seems to be set to a GUID defined in ksproxy.h for what reason, I do not know. Perhaps to permit multiple implementations of ksproxying? I would have thought this was known by the KSCATEGORY_CAPTURE GUID. FriendlyName is clear. PageAliases is completely unclear. I cannot find any mention of it via google or the directx docs. This appears to be the only inf file it exists in. PinFactory is equally opaque. It exists in several inf files, but with different GUIDs. Is this something I need to understand or can I just close my eyes and "la, la, la....". Regards, Tom Udale PS one last slightly random question. Does an AddReg section always "Device Parameters" subtree or is it specific to the top level inf section? Tag: Using system DMA in PCI Device Tag: 34274

    - How to make WPA error indication? Not sure if anyone wants to tackle this one, but here goes: In my 802.11 driver I simulate two MIC failures within 30 seconds - to test "countermeasure" feature of WPA. After 2nd failure I make indication of NDIS_802_11_AUTHENTICATION_REQUEST , with Flags = NDIS_802_11_AUTH_REQUEST_PAIRWISE_ERROR. The Funk Odissey client understands this indication, sends EAPOL pairwise error packet, the AP receives it, etc - all as expected. But WZC (update 815485) just ignores my indication.

    - negotiate paper sizes with printer driver? Hi, for a bitmap printer driver I would like to adjust the paper size to the printed area. Consider e.g. a image drawing program (MsPaint) that wants to print a 600x600 pixel image into a printer driver with 600dpi. Is there a possibility to negotiate a custom paper size of 1x1 inch? As a second example, take the acrobat reader, who has the information about the used paper coded into the pdf. There is an option in the Advanced dialog "Choose Output Tray by PDF paper size". Do I have to support all known paper types, or is there a possibility to negotiate the desired paper size with the application prior to printing? thanks in advance Dirk Tag: Using system DMA in PCI Device Tag: 34255

    - Bitmap Printer Driver (reference implementation)? Hi, I'm in the need to write a printer driver that can write a bitmap file on a W2K od XP system. I searched this newsgroup and found that a few other people where in the same situation. The proposed method seems to build upon the oemuni sample and to hook into the FilterGraphics method. Before I start coding such a driver on my one, I would like to ask, wether there is a reference implementation of such a driver, or wether anybody can provide his source code to the community? BTW.: There is a GPLed print driver in SourceForge called PrintMirror, that writes to a bitmap and EMF file. This is a custom printer driver and not based on the unidrv architecture.

    - HID Minidriver for Media Center PC remote Hi, I am trying to develop an HID Minidriver that interfaces to a Media Center PC remote control using the Consumer IR block inside a Super I/O device. This device is on the LPC bus, but the DDK says it's ok to have HID Mindrivers on buses other than USB. In any case, the sample drivers are very helpful, especially the new virtual HID Minidriver in the Windows 2003 DDK. (kudos to Kumar Rajeev & Eliyas Yakub). However, I got stuck when I tried to write a HID_REPORT_DESCRIPTOR for the remote. I studied this Microsoft document: Using the Remote Control Device with Windows http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwmt/html/remote_control.asp I also read the entire DDK section on Interactive Input Devices a few times. And I read most of the USB Device Class Definition for Human Interface Devices (HID) Ver 1.1 along with the USB HID Usage Tables Ver 1.11. I am still confused about how to write a report descriptor that meets the requirements specified in the Microsoft document about "Using the Remote Control Device with Windows". Usage page and ID's are provided for mapping the WM_INPUT messages but the document does not explain what usage page and ID's should be used for the APPCOMMAND_ and VK_ buttons. Would it be just Keyboard? (usage page 0x01 usage ID 0x06). Would Microsoft Media Player see these buttons? Is it correct to map the entire remote using a single report descriptor? Is there some kind of fatal flaw in my approach? Given the limited scope of the Media Center PC remote, would it be possible for Microsoft to publish the report descriptor that meets the requirements of the remote? Thanks in advance for your help.

    - Non deterministic register access in HwFindAdapter Now that I'm on the right path with my video miniport driver, Im having some difficulties with the PC-Card. First off, when I wrote a standard miniport I was able to successfully retrieve resources and map them and then turn on the video display. This worked 100% of the time. But that was not the correct method for dealing with a display. So i rewrote it using only the VideoPort functions. I do get the cards resources, just a small register range, and am able to map them. But when I go to enable the card (tried in both HwFindAdapter and HwInitialize) and the device turns on, maybe 5%-10% of the time. I can't explain this. All I'm doing is writting a simple value to one of the mapped registers. And let me point out that under the other method I was getting 100% success so I do not think it is anything dealing with the PC-Card. Any help you can give would be appreciated. -- Brian V.

    - Sending MMC 4 commands All, I want to send MMC 4 commands to a DVD burner (Plextor 708A, supports +R/RW and -R/RW) for data storage purposes. I've downloaded the DDK and gone through MSDN and a couple of driver development books over the past few days, I nothing has jumped out at me as a way to send the commands. Now, is there some generic SDK class that will allow me to talk to the ATAPI or some other I/O driver to send the commands, or do I have to write a filter driver (or something similar) as a DLL for my application to talk to, or do I have to write a driver specifically for the burner?

    - problem: a pci device with no memory IO or port IO addresses?? hi, I am a newbie in device driver development area and also don't have detailed knowledge on pci device internals, design specs etc. in addition, let me tell you that I am not looking for a way to write a device driver (at least for now :) but, I am confused with the my system's pci device configuration and cannot explain this sitution. please find the deails below: the hardware of concern is a PIII module with the popular Intel PIIX4E chipset (82371AB/EB) and running Windows XP as the OS. first let me emphasize that PIIX4E is a multi-function pci device and those are: 1. PCI-ISA bridge 2. IDE Controller 3. USB Controller 4. Power Management Function when I look inside the 'device list' window, all functions BUT the power management function are listed. this was the first confusion point for me. after that, I had tried some utilities, apps (like pci sniffer, windriver) hoping to list all details of my enumerated pci devices. the result was still amazing to me. With all of such utilites I was able to see all the functions of my pci devices including the power management part, but this time I had realized that even though some of the devices are listed with a corresponding memory IO and/or port IO resources, some -like power management device- do not contain any memory IO or port IO resources. my question is -simply- how can this (a pci device with no memory or port IO sapce) be? is this something meaningfull, or am I missing something with pci technology. for instance, is it possible that the system knows this device as a "bridge" (I don't know between what)? from another point of view, when I want to read/write a single register of power management function, which addresses should I use? I think I have to write a device driver to run on XP but which IO should this driver access? I am really stuck due to this problem. your help is really appreciated, thanks in advance. serkan Tag: Using system DMA in PCI Device Tag: 34241

    - help for capture device Hi, In my quest to understand and to be able to build a non-wdm capture driver, I have some question. I want to get the big picture... I think it goes like this: * UserDriver/App - create a buffer large enough to hold one frame 1. calls read (wich is direct io in driver) - waits for read to complete * Driver - gets the read IRP and the MDL describing the memory from the I/O manager - use dma (scatter gather maybe) to fill this memory - completes request * UserDriver/App - uses buffer to draw frame - go to 1 Is this right or am I missing something ? The I/O manager builds an MDL, but does it lock these pages ? Another thing is since a keep using the same buffer, it recreates the same MDL each time, doesn't this cause an overhead ? And can I get an DmaAdapter for a non-WDM driver ? It seems that IoGetDmaAdapter needs the PDO, I don't have that, can I get it ? Is there another way for non-wdm drivers ?

    - AllocateCommonBuffer Can someone verify an assumption for me ? I am using Windows XP DmaOperations->AllocateCommonBuffer to allocate a really large (64 to 96 Megabytes) buffer for Device DMA. I have 1Gig memory. It appears that if there is enough memory in the NonPagedPool, AllocateCommonBuffer will get the data from the NonPagedPool. I have been able to adjust the NonPagedPoolSize through the registry. However, even if there isn't enough NonPagedPool, The AllocateCommonBuffer operation eventually returns a pointer (success). This takes about 55 seconds, and the Windows XP boot appears to freeze during that time. My question: It doesn't say in the documentation that AllocateCommonBuffer has to use the NonPagedPool. Does it probe and lock pages, or perform some other operation that will ensure that the memory will always be available for DMA? Am I guaranteed non-paged memory when this routine returns and gived me a pointer? Is that what is taking so long? Thanks in advance for your help. Jay Tag: Using system DMA in PCI Device Tag: 34203

    - Questions about 802.11b WEP keys and wireless NIC cards Howdy. I'm writing an application that uses the PCAUSA rawether tool to set various settings on 802.11b wireless cards. Rawether (amoung many other things) lets user level programs get and set network adapter card properties described by the various NDIS OID values. For purposes of this question, I am working with 802.11b infrastructure mode using WEP authentication as you would find in a home or small office. No server based authentication is used, I'm working with the access points and wireless adapters you would purchase at Best Buy. I am able to get and set SSIDs on most wireless cards, and am able to set WEP keys for most wireless cards, but I am running into some anomalies. In particular, when I set the WEP key with my application, the settings usually do not persist through a reset, but when I use WZC or the OEM setup utility to set values then the WEP keys and SSID settings persist through resets, even if I disable WZC and the OEM setup before I reset. I'm trying to figure out why this is happening. Here are some questions I have about WEP based on the IEEE guidelines for 802.11 network adapters ( http://www.microsoft.com/whdc/hwdev/tech/network/802x/80211_netadapteula.mspx ) : 1) Under OID_802_11_ADD_WEP it talks about global and per client keys. I'm a little hazy on what these terms mean. I talk it that a global key is the WEB key that we usually use with garden variety access points. Are there access points that support a different key for each client ("per client"?). 2) When setting a value for OID_802_11_ADD_WEP the guideline says about the NDIS_802_11_WEP keyindex value: "Specifies which key to add or remove. The global keys are represented by values of zero to n. When bit 31 is set to 1, it indicates the key used to transmit to the access point. When bit 30 is set to 1, it indicates that the key is a per-client key". What is this all about? In my experiments, setting bit 31 of the key index seems to make no difference, and setting bit 30 causes the call to fail. 2) The standard says "When this OID sets the same index twice, the miniport driver should overwrite the previous WEP key at that index". What does that mean in practice? What is the difference in adapter behavior if I only set the wep key an a particular once or twice? Besides making a valid call to OID_802_11_ADD_WEP and turning WEP on by setting Ndis802_11WEPEnabled to Ndis802_11WEPEnabled, is there anything else I should do to make the WEP key persist through a reset? Any hints will be very welcome. Tag: Using system DMA in PCI Device Tag: 34192

    - 1394 Address Range Allocation I'll preface my question by stating that I am an extreme novice when it comes to driver development. I'm basing my driver on the 1394diag DDK sample. I would like to understand how one makes use of FifoSListHead. My 1394 device will be transferring 32MBytes of data. Since data integrity is a must, asynchronous transfers will be used. I have an application that allocates 64MBytes. I make a call into the driver via IOCTL which calls AllocateAddressRange(). Is it possible to have the data that comes across the bus DMA'd to the buffer allocated by the application? The 1394Diag sample allocates a buffer of nLength and then allocates memory for the array of ADDRESS_RANGE structures. Do I need to allocate the buffer of nLength size or is it possible to map the User mode allocated buffer to physical memory? It appears to me when using Win1394.exe and selecting Fifos really has no effect. The 1394diag driver seems to only allocate one MDL. Am I interpretting this right?

    - GetPrinterDataFromPort() and GetPrinterData() I am attempting to communicate from the Printer Interface dll to the Language monitor under Windows 2000. There is no documented way to do this, but there are messages throughout the Google usenet archive about people using the spooler GetPrinterData() call which makes a call to GetPrinterDataFromPort(). However under Windows 2000 with a user-mode driver I am unable to get this to work - calling GetPrinterData with a value that is not in the registry just returns ERROR_FILE_NOT_FOUND. So my question is whether there is a way to get this to work? If not what is the recommended way to talk directly to the language monitor (to query printer parameters) under Windows 2000?

    - problem: a pci device with no memory IO or port IO addresses?? (newbie) hi, I am a newbie in device driver development area and also don't have detailed knowledge on pci device internals, design specs etc. in addition, let me tell you that I am not looking for a way to write a device driver (at least for now :) but, I am confused with the my system's pci device configuration and cannot explain this sitution. please find the deails below: the hardware of concern is a PIII module with the popular Intel PIIX4E chipset (82371AB/EB) and running Windows XP as the OS. first let me emphasize that PIIX4E is a multi-function pci device and those are: 1. PCI-ISA bridge 2. IDE Controller 3. USB Controller 4. Power Management Function when I look inside the 'device list' window, all functions BUT the power management function are listed. this was the first confusion point for me. after that, I had tried some utilities, apps (like pci sniffer, windriver) hoping to list all details of my enumerated pci devices. the result was still amazing to me. With all of such utilites I was able to see all the functions of my pci devices including the power management part, but this time I had realized that even though some of the devices are listed with a corresponding memory IO and/or port IO resources, some -like power management device- do not contain any memory IO or port IO resources. my question is -simply- how can this (a pci device with no memory or port IO sapce) be? is this something meaningfull, or am I missing something with pci technology. from another point of view, when I want to read/write a single register of power management function, which addresses should I use? I think I have to write a device driver to run on XP but which IO should this driver access? I am really stuck due to this problem. your help is really appreciated, thanks in advance. serkan Tag: Using system DMA in PCI Device Tag: 34162

    - Why does USBD "freeze" when configurating interface? I have a USB 2.0 device driver and it worked well before. But recently after I updated USB 2.0 bus (version 5.0.2195.6717, date: 6/19/2003) and host controller (version: 5.1.2600.1, date: 2/15/2003) driver from Microsoft website, it doesn't work anymore. Then I made a various testing and found it works on USB 1.1 port, works on manufacturer-provided USB 2.0 bus driver/host controller driver (from a floppy disk with USB 2.0 card), and I recalled that it also worked on a beta version of Microsoft provided USB 2.0 bus driver when I was developing the device driver.

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've configured Wireless network to a "Adhoc" mode, Network authentication to "WPA-None", and Data encryption to "AES". Finally, my device driver has received SetInformation of OID_802_11_ADD_KEY, but the key material was not same data that i've entered as a Network key using WinXP Wireless Client program. In contrast, the key material was same data that i've entered if i select "WEP" as a data encryption. Please, let me know why the key material was not same data that i've entered and give me some information about key generation algorithm if any. Thank you. //Daum Tag: Using system DMA in PCI Device Tag: 34140

    - Question: Learning FSD Hi, I'm an experienced NT KMD programmer in WDM, NDIS, video, and other filter drivers. Recently, I want to learn how to write FSDs and/or FS filters. I understand FSD is very difficult to learn compared to all other drivers I've written so far. I would like to know the best approach of overcoming the learn curve(or "cliff" I should have said). I have Nagar's book on File System. I plan to order the IFS kit and play with it. I want to know if it would be beneficial to take a FSD seminar with zero experience in FSD? Or should I learn some basic by myself then take the seminar later, so that I know better what the instructor is talking about? This will cost me more than an arm and a leg in terms of time and money. I was wondering if a FSD programmer gets better pay than a DD programmer in general? Is that correct that most FSD related work is contracted to consultants? Thanks, Calvin Tag: Using system DMA in PCI Device Tag: 34130

    - CF Card and Video Miniport Ok, so I'm trying to get resources for my CF-Card in my Video Miniport driver. In HwFindAdapter I'm doing a VideoPortGetButData and for testing have cycled through all of the possible bus types. The only bus type that returns any data is 0, Internal. I was expecting something to come up under Isa, or Eisa or maybe even PCI. But nothing. So my question is, how do I get access to my cards resources, -or- do I have to explicitly list them because CF (via cf-pc-card adapter) falls under the ISA bus? Thanks! -- Brian V.

Basically you cannot use system dma for your PCI device. If your
device does not do busmaster dma then you must use PIO to transfer
data. The CPU is far faster than the crappy legacy system dma
controller anyway.

You cannot. System DMA is ISA only.
(well, there is the so-called Distributed DMA, but is not applicable for your
case anyway).
