    - How determine network itnerface disable status ? Hi all, I am writing a gui for network adapter config tool like mux example in DDK. In my UI i want to determine if any network component is disabled or not. i can send an ioctl to the lower interface and get the connect status but how can i find out disabled / enabled status ? "Network and dial-up connections" windows is able to show the status of any netowrk adapter as disabled/connected/network cable unplugged. how can i get this status ? This is for win2k and above.

    - commit charge(k) in Windows 2000 Task manager After testing my driver for few hours, I observe a raise in commit charge(k) value in Task Manager of Win 2k. I dont think there is memory leak in my driver because if there is it would be traced by driver verifier. Also I dont see any significant raise in Kernel memory section of Task Manager. I cannot understand what the raise in commit charge means. Tag: User-mode class-specific request? Tag: 31911

    - Update PnP driver Hello, I trying to make a setup application to update a PnP driver for 1394 devices. The devices are installed but possible not connected to the computer during the update session. A new software release means also a new driver and if a user want to use the new software he must update first the driver for all 1394 devices. It would be nice if the driver for the devices can be installed without interaction with the user. Maybe someone out there with suggestions? Regards Ronny Tag: User-mode class-specific request?

    - FileSpy IFS sample Hi, I'm playing with the IFS kit's filespy sample as a learning exercise: What I'm trying to do is obtain a file's path-name whenever an IRP_MJ_CREATE completes successfully - I'm not interested in knowing the name at any other time - the whole filename caching that filespy does is much more complex than I require. So, is there a simple way to obtain the name at IRP_MJ_CREATE time? Maybe through the parameters that the create IRP passes? I am aware that sometimes obtaining the filename through a FILE_OBJECT structure is not possible, because the IRP_xxx routines might be execute at IRQL dispatch-level - but maybe there's a shortcut I can use to simply get the name at creation/open-time? Please advise me of any potential danger areas, I need to learn this stuff properly.. TIA James Tag: User-mode class-specific request? Tag: 31890

    - sequence of dispatch routines Hi, I looked at the SniffUSB (usbsnoop(y)) project and I can't figure out why the dispatchroutines of the filter driver are carried out before the dispatch routines of the function driver. It is a lower level filter driver, so I would expect that an IRP will be completed by a functiondriver routine before the filter driver can dispatch the given IRP. Could some-one give me a clue on this, I would really appreciate it. Thanx Tag: User-mode class-specific request? Tag: 31813

    - NDISUIO, problem reading packets Hello, I was wondering if someone could help me, I am using the standard NDISUIO sample of the Windows XP DDK in a WIndows 2000 FREE build environment. I have managed to install it successfully under WIndows 98 and 2000 and XP but run into the following problems: - Under Windows 2000 none of the adapters bind - Under Windows 98 I can't seem to retrieve the packets that are sent back using an MJ_READ command. The packets I get back do have the correct Header information (802.1X EAPOL) and the sizes are correct. 60 bytes for the EAPOL Identity. But the data returned using the IRPS is full of hex 0xAFAFAFAF. Retrieving and setting OIDS works perfectly. Has anyone else run into these problems? I do remember someone stating that MJ_READ and MJ_WRITE not working with a Windows 98 driver and is this what I am experiencing? I don't know what is going wrong under Windows 2000 but maybe the inf file is incorrect. Thanks Tom Rixom Tag: User-mode class-specific request? Tag: 31808

    - need some help with VideoPortGetBusData HI all, I am very new to this field of device driver I am using windows 2000 ddk kit and developing this driver on windows 2000 only. Please help me out in getting the base address of the adapter device. I am using Matrox graphic chip G200. i want to write a miniport driver for this chip. If I look into device manager, it gives me information that this device is on pci bus 1, device 0. So to get the base address of this device I am using VideoPortGetBusData, according to document it should return the length of the data return. So I am checking it. If I use it as follows it allways returns 0. PCI_COMMON_CONFIG PciData; vpStatus = VideoPortGetBusData( hwDeviceExtension, PCIConfiguration, 0, &PciData, 0, PCI_COMMON_HDR_LENGTH); VideoDebugPrint((0,"\nvpStatus is 0x%x \n",vpStatus)); Please let me know were am I going wrong............ Also I have tried with be EisaConfiguration. For EisaConfiguration it returns same 0...... vpStatus = VideoPortGetBusData( hwDeviceExtension, EisaConfiguration, 0, &EisaData, 0, PCI_COMMON_HDR_LENGTH); VideoDebugPrint((0,"\nvpStatus is 0x%x \n",vpStatus)); BUt for CMOS it returns 64. It fills up the Pcidata buffer......... vpStatus = VideoPortGetBusData( hwDeviceExtension, Cmos, 0, &PciData, 0, PCI_COMMON_HDR_LENGTH); VideoDebugPrint((0,"\nvpStatus is 0x%x \n",vpStatus)); I am not getting what exactlly it means..........

What are the specific commands I need to search all memory on my computer? A situation where this is needed is suppose you have a script that is encrypted.

    - WDM use of IoCreateDevice I believe it is correct for AddDevice to call IoCreateDevice and IoCreateSymbolicLink and then call IoAttachDeviceToDeviceStack for the AddDevice physical device object and the IoCreateDevice functional device object. But if I need to additionally call IoCreateDevice and IoCreateSymbolicLink for each physical device found and passed via IRP_MJ_PNP IRP_MN_START_DEVICE, is it also necessary to pass those IoCreateDevice functional device objects to IoAttachDeviceToDeviceStack? If yes, what physical device argument should be used for IoAttachDeviceToDeviceStack? IRP_MJ_PNP only passes a functional device object argument, from the AddDevice call to IoCreateDevice, not a physical device object. Thanks. Tag: User-mode class-specific request? Tag: 31771

    - 1394 Isoch operations After IsochAllocateResources, when should I call Request_Talk or Request_Listen? Should I call Request_Talk ( or Request_Listen) everytime after attaching buffers or only after Allocating buffers. I DONOT have any start time requirement. Now I am implementing : Method in use: -------------- 1. REQUEST_ISOCH_ALLOCATE_RESOURCES 2a. REQUEST_ISOCH_ATTACH_BUFFERS 2b. REQUEST_ISOCH_TALK (or) REQUEST_ISOCH_LISTEN (later REQUEST_ISOCH_DETACH_BUFFERS...sometimes it happens before talk or listen request) Repeat 2a and 2b Repeat 2a and 2b Repeat 2a and 2b Repeat 2a and 2b 3. REQUEST_ISOCH_FREE_RESOURCES Can I do like this -------------------- 1. REQUEST_ISOCH_ALLOCATE_RESOURCES 2b. REQUEST_ISOCH_TALK (or) REQUEST_ISOCH_LISTEN 2a. REQUEST_ISOCH_ATTACH_BUFFERS (later REQUEST_ISOCH_DETACH_BUFFERS) Repeat 2a Repeat 2a Repeat 2a Repeat 2a 3. REQUEST_ISOCH_FREE_RESOURCES I think second method should work. But since first method is working, I didnot modify. I think this is waste of processing power to call talk/listen after each attach. How others are implementing? Thanks.

    - Using SetupDiSetDeviceRegistryProperty to change driver on a particular device A while back I spent a lot of time on NTDEV asking about changing the PnP IDs in a SCSI Bus filter so the PnP system would load a different class driver on a device. That worked fine for me, once I understood which IRPs to muck with. I didn't get around to running verifier on it, but from recent posts, running verifier could be a problem for me. Without Verifier, I could change all the instances of DISK to DIAG, for a particular PDO, and the system thought I had a DiagDevice. My Inf installs my DiagClas driver, I can enumerate the DiagDevices with the interface GUID the DiagDevice class driver exports, and everyone is happy. During that discussion, one of the MS storage guys suggested that SetupDiSetDeviceRegistryProperty, with the SPDRP_SERVICE property, could be used to change the driver for a specific device. For another use, I don't want to use the filter, so I'm trying to do this, with mixed results. The registry entry gets changed OK, and stopping and restarting the device causes my custom class driver to load, but it's not causing the PnP system to think it's something new, the system still thinks that it's a disk, so partmgr still attaches to it. Maybe I could use it that way, except that enumerating the interface GUIDs for disk and my diag driver doesn't find anything at all. So somehow this different driver in the stack for this one devnode has not only failed to produce a DiagDevice, it causes some impairment of the normal disk interface. I tried SetupDiSetDeviceInterfaceDefault with the DiagClas interface GUID in the SP_DEVICE_INTERFACE_DATA for the device, but that resulted in a 0xE0000225, which is ERROR_NO_SUCH_DEVICE_INTERFACE, in SetupAPI.h. Removing and re-enumerating results in my class driver not being loaded again. This isn't a surprise, since my custom class driver isn't signed, and probably never will be, so I expect the system to load the signed disk driver in the absence of my filter. So at this point, all I've done is substituted my custom class driver for disk.sys, and that's not what I want to do. I want to remove the device as a disk, and load it as a DiagDevice. So my question devolves to: Constraining to user-mode only, what else do I need to do to create a DiagDevice, instead of a disk with a different class driver? Remember that I can already do this OK with a filter, I'm trying to do it without using the filter. Since SPDRP_HARDWAREID and SPDRP_COMPATIBLEIDS are R/W, should I be changing those, too? Anything else I should change? Thanks, Phil -- Philip D. Barila Windows DDK MVP Seagate Technology, LLC (720) 684-1842 As if I need to say it: Not speaking for Seagate.

    - Access VGA port SDA and SCL lines HI, I am using INTEL 82845G grapghic controller (which support DDC2BI protocol)and working on windows 2000 operating system. I am developing a software which will interact with the monitor through VGA port's SDA(system data line) and SCL(system clock line) data lines. According to access.bus protocol, pin 12 and pin 15 of a VGA port (D_SUB connector) are for SDA and SCl data lines. And they have given a protocoll about the data which should be sent to these data lines. Now my problem is how to send the data these lines through program. setSDA(), getSDA() .... should be the underline functions which will interact with the hardware (VGA port), which I guess should be implemented in the driver , now how to access these functions through my software? If I have to write a driver, I can use VideoPortDDCMonitorHelper function , but here also I have to supply the address were I want to send the data. I have to write the functions like typedef struct _I2C_CALLBACKS { PVIDEO_WRITE_CLOCK_LINE WriteClockLine; PVIDEO_WRITE_DATA_LINE WriteDataLine; PVIDEO_READ_CLOCK_LINE ReadClockLine; PVIDEO_READ_DATA_LINE ReadDataLine; } I2C_CALLBACKS, *PI2C_CALLBACKS; VOID I2CWriteClock(PVOID HwDeviceExtension, UCHAR data) { const ULONG nbitClock = 3; const ULONG Clock = 1 << nbitClock; PHW_DEVICE_EXTENSION hwDeviceExtension = HwDeviceExtension; ULONG ul; P2_DECL; ul = VideoPortReadRegisterUlong(DDC_DATA); ul &= ~Clock; ul |= (data & 1) << nbitClock; VideoPortWriteRegisterUlong(DDC_DATA, ul); } Can anybody over there guid me , how to write these functions and the addresses which I should supply so that it will get written on VGA port's 12'th and 15'th pin. for eg. this is sample code from 3dlab's driver, Now if I want to use same code, what will be the value of DDC_DATA, DDC_DATA is actually a virtual address of the DDC_control registor. Will it be same for all graphic chips? VOID I2CWriteClock(PVOID HwDeviceExtension, UCHAR data) { const ULONG nbitClock = 3; const ULONG Clock = 1 << nbitClock; PHW_DEVICE_EXTENSION hwDeviceExtension = HwDeviceExtension; ULONG ul; P2_DECL; ul = VideoPortReadRegisterUlong(DDC_DATA); ul &= ~Clock; ul |= (data & 1) << nbitClock; VideoPortWriteRegisterUlong(DDC_DATA, ul); } Also I want to know who supply the PVIDEO_PORT_CONFIG_INFO ConfigInfo parameter in the Find Adapter function? As to get the base affress I need AdapterInterface = PCIBus, but in my case, this whole struture is something like not accesseble.

    - Where should KDevice::CreateLink() be called from? In order to create a symbolic link to myDevice should pmyDevice->CreateLink() (Class myDevice derived from base class KDevice) be called from myDriver::DriverEntry() or from the device Constructor myDevice::myDevice()? The SoftIce DriverWorks documentation does not specify. Thanks. Antranik Tag: User-mode class-specific request? Tag: 31705

    - driver compile problem Hi, I am writing a WDM video capture driver by Win2000 DDK and VC6.0. My environment is Windows98 se. I put my source code under c:\xxxxxxx\wdm.nt directory, then build the source code. The generated .sys works well under Win98/ME, but it crash the win2k/xp immediately when it starts. Later I rename the directory to c:\xxxxxxx\wdm1.nt, (one more character), it works well on all Windows OS. My question is: Does it have any relationship between the source code directory name and generated .sys file? Or it is VC linker's problem? Tag: User-mode class-specific request? Tag: 31703

    - Blocking in IRP_MJ_WRITE, KeDelayExecutionThread, threads I have a question about KeDelayExecutionThread(). Do I understand the documentation correctly: If I call KeDelayExecutionThread() to block in my IRP_MJ_WRITE handler, and the thread which called WriteFile() is terminated by TerminateThread(), will Ke... return immediately, no matter what I specify for the Alertable parameter?

    - Error msg upon adding printer Hi, I am trying to install my custom printer driver via the Add Printer Wizard. Upon clicking on Finish, I get an error message saying: "Printer Driver not installed. Operation could not be completed." My .inf file installs 3 files: a graphic DLL, a UI DLL and a print processor. Error messages in setupAPI.log complained about the files not having digital signature information. This also happens to samples that come with the DDK. Does anyone know why I get the error message and how I can fix it ? Is it a must to have the DLLs properly implemented ? My goal at this stage is to install my print driver that does nothing. Regardless of what it does, I want to be able to install it at least. Many thanks, Michael. Tag: User-mode class-specific request? Tag: 31700

    - USB Bulk In&OUT each need two handles? Hi If my usb device has two endpoints - Bulk_IN and Bulk_OUT. I try to use the bulkusb sample code within windows 2000 ddk to communicate with my usb device. According to the sample code, it seems that I need to use two GUID based string plus the "\PIPEXX" string to CreateFile() in test application and get back two handles, one for Bulk_IN and the other for Bulk_OUT, if I need to bulk-in & bulk-out data to device. My question is that can I use one handle to bulk-in and bulk-out data ? If yes, which way is the best way and what can I do? ps. I try to use GUID based string but not plus the "\PIPEXX" string (for example, "\PIPE00") and CreateFile() is successful. The handle I got can used to send DeviceIoControl(), but can't used to WriteFile() ( or ReadFile() maybe) and gets the error code ERROR_INVALID_HANDLE. Ricky Tag: User-mode class-specific request?

    - Power Management fails with the USB 2.0 host controller Hi, We have USB to Serial port converter. We have written windows-2000/XP WDM driver for that device. The 2000/XP WDM driver is working fine with all the serial port applications. When we receive PowerDeviceD1,PowerDeviceD2 or PowerDeviceD3 we are stopping the all the USB transactions. And configuring the device (Setting the registers and starting the USB transsactions) when the we receive PowerDeviceD0. When the systems comes out of the standby mode, my device (Application) works fine with the 1.1 hostcontroller. But the same thing is not happenning with the 2.0 hostcontroller. i.e My device doesn't work when system comes out of standby mode. I Debugged this issue and I found that VendorCommands (For Configureing the device registers) and Usb Bulk requests are failing when we are processing the PowerDeviceD0. That is why device is not working properly. URB status is 0x80000300 with VIA2.0 Hostcontroller URB status is 0xc0000005 with NEC2.0 Hostcontroller Operating system used windows-2000. Does anyone have any idea why this not work? Thanks in advance B. Madhukar Reddy Tag: User-mode class-specific request? Tag: 31693

    - usermode memory management In Kernel space, after we can allocate memory, we can also get a table from debugger to see what is the size of memory allocated, how many allocations done, tag of allocation, how many allocations are not freed/leakage. Do we have any mechanism that give same type of info in user mode Apps when I use virtualAlloc() and virtualFree() functions. I want to make sure I am not causing memory leaks in user mode App and how to check that. Thanks. Tag: User-mode class-specific request? Tag: 31671

    - NDIS Intermediate driver for CE To whom it may concern, I am desperately looking to find example code to write an NDIS Intermediate driver for CE. I found IMSamp.exe, which contains examples for desktop platforms. However, my understanding is that the NDIS IM driver for CE is different. Thus, any help that you can give me will be greatly appreciated. We have purchased MSDN Universal support under bryan.glancey@mobilearmor.com.

    - Question regarding netvmini NDIS driver! Hello, I am a NDIS newbie, I was trying to understand the NDIS device driver and write my own. For that I am going through the netvmini ndis driver source code, in the DriverEntry routine, the global variables are being initialized, and the comment says that "GlobalData structure is used to track the multiple instances of the same adapter". What does this mean? In which scenarios we might be having multiple instances of the same adapter running? Also, why do we initialize the GlobalData before registering the unload handler (I know the comment says that "unload handler has a more global scope"??)? Any help in this regards would be highly appreciated. Regards, Tar Tag: User-mode class-specific request? Tag: 31640

    - NDIS IM & Miniports & Bluescreens & how to support Hello, There is a well known problem between NDIS IM and Miniport drivers where the addition of the IM causes the Miniport to bluescreen. The solution is always upgrade the miniport to the latest, which has solved the problem. My problem as a vendor shipping an IM is when our product is installed the bluescreen happens so it is our products fault. Our support folks don't like having to tell customers to go get the latest driver from their NIC vendor. When I have looked at the fault it typically is a pointer dereference of an information buffer in a get or set oid. Does anyone have any idea what the underlying problem is with the minport. Why does it work without the IM? Is there anyway for the IM to protect against such problems? Thanks in advanced. Regards, Michael Wright Tag: User-mode class-specific request? Tag: 31632

    - NDISUIO problem, can't retrieve NDIS packets Hello, I am using the NDISUIO sample and have successfully installed it under WIndows 98. I have got everything working, binding, querying OIDS and so forth but as soon as I try to read packets I get the right size for the data packet but the data itself is full of 0xAF(HEX). I have used both the MJ_READ method and a IOCTL command to retrieve the buffers into user space but both give the same result. I think it is going wrong when retreiving the actual NDIS buffer but the code for this is all Microsoft. Can someone point in the right direction? Maybe I am building the sample incorrectly?

    - Windows DDK (XP SP1) Hi, I upgraded my PScript printer driver plug-in to the latest DDK i.e., XP SP1 DDK and all my balloon tips are not working now. After some debugging I found out that registration for the tootip control is failing i.e., my SendMesssage command with TTM_ADDTOOL fails and return false. There is no error registered, when I called GetLastError() it returns success. Same code worked when I compiled under older windows 2000 DDK. Also attached is the code snippet. Thanks, Athar Ahmad.

    - DDK Kernel Driver I have ran a RunTime function _Strdate(), which retrieves date in sd.c file compiled with Microsoft Compiler. It ran properly. But when I linked that sd.obj file to my driver, then it resolved those linker errors e.g., for _strdate() function . the exec. file sd ran upto my expect. . Before linking my driver with this sd.obj, my driver ran upto my expect. Now after when I linked out sd.obj to my kernel driver , It imported the _strdate() into my driver, then my driver couldn't even load ??? Tag: User-mode class-specific request? Tag: 31616

Hi,

Is there any way for a User-Mode Application to send a
class-specific request(hid spec 1.1 - section 7.2) to a
USB HID device in Windows (with or without the Driver
Development Kit)? I am trying to send a Set_Protocol
request(7.2.6) to a HID device. Everything I've read so
far requires driver level stuff.

Excerpt from Hid Spec.
7.2 Class-Specific Requests
Description:
Class-specific requests allow the host to inquire about
the capabilities and state of a device and to set the
state of output and feature items. These transactions are
done over the Default pipe and therefore follow the
format of Default pipe requests as defined in the USB
specification.

Thanks for the help,
Jackson
