    - Programmatically power up or down a particular device [on a hotplug bus] Is there any documented way to programmatically change the power state of a device (i.e. power off or power on) from usermode? (I'm not particularly knowledgeable about programmatically controlling power management...) In particular, I'm looking to be able to power on or power off an arbitrary USB or 1394 device (i.e. not a device I wrote the driver for). For example, I might have an externally powered USB or 1394 device that is attached to a battery backup system that is separate from the battery backup system the computer is on. I can determine whether the battery backup system that the external device is on is low on power or not, but I need a way to gracefully shutdown the appropriate device before an impending power loss. Because the computer itself is on a different battery system (say for the sake of argument that it is a higher capacity battery system), I don't want (or need) to shut down the computer entirely, just the affected devices. Assume for the moment that I have control over any applications that might be using said devices and can make sure that they relinquish usage before I try to shutdown the device. One option I see is to request a graceful device removal (e.g. CM_Request_Device_Eject_Ex), since the devices are going to be on a hotpluggable bus, but this seems suboptimal for what I'm looking for.

    - Q) NDIS_STATUS_PENDING for a MiniportSetInformation and NdisMSetInformationComplete. Dear all, I'm developing NDIS miniport driver for Win2K and WinXP. If a Miniport D/D return NDIS_STATUS_PENDING for a MiniportSetInformation, it will need to return the final status for the NdisMSetInformationComplete. However, the NdisMSetInformationComplete does not have NDIS_OID or Informationbuffer that was from MiniportSetInformation. So, I think it is impossible to identify what the paired MiniportSetInformation is if there were multiple MiniportSetInformations with NDIS_STATUS_PENDING. Q) Between returning NDIS_STATUS_PENDING for a MiniportSetInformation and NdisMSetInformationComplete, is it guaranteed not to issue another MiniportSetInformation from the Window operating system? This can apply to MiniportQueryInformation/NdisMQueryInformationComplete as well. Have a nice weekend. Thank you. // Daum Tag: Saving Device Parms to the registry Tag: 78138

    - bug found only in signed printer driver, how to debug? I recently got my printer driver signed. After getting signed, our QA group found a bug. When I (and then they) tried to reproduce it, we found it only happens with the signed version. The unsigned version does not have the problem (it's a spooler crash when doing a test print as part of the install; test prints after install and normal application prints work fine). So I'm wondering how to debug this. I can't very well submit a debug version of the driver to be signed (cause then it will be part of windows update and all our customers will get this debug driver). And debugging the non-debug, signed, version of the driver is less than productive. Any ideas? Thanks, ScottR -- Scott Robins Tag: Saving Device Parms to the registry Tag: 78136

    - UpdateDriverForPlugAndPlayDevices does not remove all devices. Hi, I have a device driver that has many virtual devices that have been added through PnP via the AddDevice DriverObject Function call via the PnP system. I can have up to 255 of these devices for this driver. When I have created a new version of this driver, I update it with the system call, "UpdateDriverForPlugAndPlayDevices()". I was hoping that this call would force a call to my driver to "REMOVE_DEVICE" one at a time until there are no devices. At this time the PnP system would call my unload routine. Then when the PnP system calls the AddDevice routine the new driver would be loaded. It does work this way if I only have one or two devices on the driver. However, If I have more devices than this, then the PnP system sends the "REMOVE_DEVICE" IOCTL for a few of them, then calls the AddDevice for the devices that were just removed. Then it repeats this until all of the devices have been removed and re-added. Consequently, the number of devices never reaches zero and the unload routine is never called. At the end of the driver update, a reboot is required, because the previous version of the driver is still the running driver. My question is this: Is there anyway to tell UpdateDriversForPlugAndPlayDevices to remove all the devices before adding them back? Thanks in advance, -David G Tag: Saving Device Parms to the registry Tag: 78134

    - System hang Hi all, got a nasty system hang issue that I have about run out of ideas on: We only get the hang on an Asus A6000 U, we havent seen it on any other laptop, and, in fact, the driver for this device has been WHQLed in various versions for the last 6 months or so. The device is a PCCard device with an FPGA interface (It is also made by us). We are using WinDbg on a 1394 cable to debug. The hang happens with release drivers, and debug drivers that have no DbgPrinting. With a lot of DbgPrinting, the laptop doesnt hang. With just one DbgPrint at the very start of the Isr, wew do get tha hang, but WinDbg does not show a continuous trace, so this is not an unhandled interrupt as the ISr is not getting called. We cannot break into the hung laptop using Ctrl+Break. We can also not generate a user crash via the RightCtrl + Scroll Lock x 2 technique. Tag: Saving Device Parms to the registry Tag: 78125

STATUS_NOT_SUPPORT (0xc00000bb) returned by IoCallDriver when I pass down IRP_MN_QUERY_INTERFACE irp to lower driver stack PDO (which is BTHPORT). The driver is enumerated by BTHPORT all right, *I assumed*. One way or another, I may get STATUS_INVALID_DEVICE_REQUEST with various attempt to send IRP_MN_QUERY_INTERFACE. Doron suggested that I might have the interface structure not well formed. I'm not sure what may the interface structure I need to form. I don't think I'm doing anything different to query interface.

    - Vista graphics question Hi, I just downloaded the Feb Vista CTP Beta. I have installed in the system a NVidia Quadro FX 3400 video card which has a beta Vista driver and the "aeroglass" display subsystem seems to be working correctly. The display driver in Hardware manager claims to have 2 drivers for the NVidia card, a video card "miniport" driver in the Drivers directory and a .dll display driver in the system32 directory. This sounds just like Win XP/2000. However when I attach a debugger to the system, the only file that I see load is the video card miniport driver. Does this mean that the display driver is not used, and if so why does NVidia have a display driver? Tag: Saving Device Parms to the registry Tag: 78096

    - How to identify the driver that prevents the OS from hibernation? I'm occasionally getting error 0xc000009a, reporting that hibernation got disabled due to "insufficient resources". I suppose this is a driver issue, and I'm wondering how one can go about diagnosing it. It appears to be memory-related, it happens on a desktop with 4GB RAM and on a notebook with 2GB RAM, never on any of the machines with a smaller amount of memory. What could be the reasons for such behavior, and where to look for the evidence? Your advice would be appreciated. I've tried on different forums without any success. I'm running Win 2k3 EE + SP1.

    - MAC Addresses Returned By OID_WAN_PERMANENT_ADDRESS How does NDISWAN generate the MAC address returned through a query of OID_WAN_PERMANENT_ADDRESS or related OIDs? The low-order 4 bytes are always " RAS" while the high-order 2 bytes seem to be different on different laptops/desktops. For example, on one desktop these bytes are 0x2c-0x31, while on another they are 0x4A-0x47. Also, since NDISWAN is in the way and appears to spoof a MAC address for the underlying WAN device, does that device have it's own MAC address and is it accessible through any type of OID query?

    - Port Monitor memory allocation I'm still fairly new to driver development, so please have patience with me if some of my questions may seem dumb... I've written a Port Monitor dll which is supposed to intercept print jobs, write them to disk and process them further. This is working the way it's supposed to, for the most part, but a problem I am having right now is that I'm not sure how to properly allocate memory properly. I tried several methods (malloc, GlobalAlloc, etc.) to allocate space for strings, for example, but they all seem to compromise stability, either leading to outright crashes, or leading to the Spooler process terminating quietly eventually. Only using something like fixed arrays of char seems to be stable, but ... well, I don't think I have to explain the drawbacks of having to specify the size of strings at compile time... Is there something I am missing? Are there any special rules for Printer Driver DLLs for allocating/freeing memory (besides the obvious one to make sure to free everything you allocate, which I am pretty sure I am already doing)?

    - Commercial component: joystick driver controlled by user software Hello, I'm look after a commercial joystick driver controlled by my application (determine the number of axis, determine the number of buttons, transmit axis values and button values). I thing, the virtual joystick driver possible is a combination of an joystick or game port minidriver and a opportunity to control this driver through IOControl or an ActiveX component etc. which I can order about my application. Why I look after such comonent is, about the defined DirectInput interface other applications should be able to get data from my application (process communication). I thinking, the DirectInput interface is the best combination with the kind of data, which should be exchange by this interface. And destination computers where my application will be installed, dosn't have a real physical joystick. Do anyone kow such component?

    - reg. frame descriptor of USB 1.1 video class specification Hi, YUV2 Packed data format It is mentioned that USB 1.1 video class specification supports YUV2 (uncompressed) packed data format. What does that mean? what type of packing is supported i.e., 1. Y-Cb-Y-Cr or 2. Y-Cr-Y-Cb or 3. Cb-Y-Cr-Y or 4. Cr-Y-Cb-Y Also, at the host side, how does it know which packing is supported as the Frame descriptor does not have any fields to mention about that? Frame Buffer Size One sample (pixel) is 16-bit size, suppose if the resolution is 1024 * 768 then the video buffer size would be 1024 * 768 * 2 (1.6 MB). Is this correct? The buffer allocation at the host side would be Y - 1024 * 768 * 1 (8 -bit) U - 1024 * 384 * 1 (8-bit) V - 1024 * 384 * 1 (8-bit) In total it is 1.6 MB. Is this correct? Minimum and Maximum Bit rates The two fields dwMinBitRate and dwMaxBitRate are not clear to me. How will you set the value for it? For Uncompressed data, will both contain the same value? Suppose I have a frame size of 1024 * 768 * 2 (as above) and 15 frames per second then the bit rate would be 1024 * 768 * 2 * 15. is this correct? Kindly provide me the answers asap.

    - Dynamically Loading/Unloading NDIS Drivers From USB Drive Is it possible to load/unload NDIS drivers (in this case, an NDIS IM driver) on XP and W2K from a USB drive without actually installing the driver (i.e., changing the registry)? I know one solution would be to install the driver using the INetCfg API as shown in BindView, but that would require an install through an .inf file with modifications made to the registry. I wanted to see if it's possible to dynamically load the driver and avoid the registry changes. Thanks! Tag: Saving Device Parms to the registry Tag: 78013

    - Incorrect INF - Installer File ? Hallo! I have a driver, I would like to install with an INF Files because it is a PnP/WDM Driver. But when I want to install it via the Hardware-Manager, there is an error: ~"The specified place has no information about the hardware" The Hardware is plugged in. Here the content of the INF - File: [Version] Signature = "$Windows NT$" Class=Net ClassGUID={4d92c6ab-cfe1-42c8-a81b8b62ee20f9ad} Provider=%MarkusSoft% DriverVer= 4/4/2006 [DestinationDirs] treiber.Files.x86_12 = 12 [SourceDisksNames.x86] 0=%Desc_x860% [SourceDisksFiles.x86] driverbase.sys=0,.\treiber, [Manufacturer] %MarkusSoft%=MarkusSoft [MarkusSoft] %TreiberDesc%=Treiber_Inst,PCI\VEN_CEBA&DEV_2319 [Treiber_Inst.ntx86] CopyFiles = Treiber.Files.x86_12 [Treiber.Files.x86_12] driverbase.sys [Strings] MarkusSoft= "Markus Software" Desc_x860= "MARKUS" TreiberDesc= "Desc." The Files are in in the following structure: .\basisTreiber_install.inf .\treiber\driverbase.sys Does someone find a mistake in the INF? Or could this also be a problem of the SYS-File?

    - SetupCopyOemInf Failiure Hello, Attempting to install our printer driver on Windows XP Pro x64, SetupCopyOemInf() fails with error 87: The parameter is incorrect. The .INF is copied to the INF directory as OEM9.INF, and OEM9.PNF is created, which -- I believe -- is what is supposed to happen. The same .INF works properly with Add Printer Wizard. In the debugger, just after the pop-up about unsigned drivers, Continue Installation is selected, then an access violation occurs: mov [r15], eax ; ds:fffff97f`00000000=???????? The parameters to are: SetupCopyOemInf(szInf, 0, SPOST_PATH, 0, NULL, 0, 0, NULL); Also, I noticed that SETUPAPI.LOG shows a difference when installing via Add Printer Wizard and via our setup program. Add Printer Wizard: #W367 - "A valid signature ... .INF" for driver "Printers" will be installed ..." Our Setup program: #W367 - "A valid signature ... .INF" for will be installed..." The words 'driver "Printer"' are missing. Could this be a clue as to what SetupCopyOemInf() is failing on? Thanks in advance. Tag: Saving Device Parms to the registry Tag: 78008

    - Does the system automatically disable drivers? Are there situations when the system will automatically disable (i.e. set Start to SERVICE_DISABLED) a legacy driver configured as a system-start driver? Mike Tag: Saving Device Parms to the registry Tag: 78004

    - OID_TCP_TASK_OFFLOAD In DDK doc is written: "If an intermediate driver modifies the contents of TCP packets that it forwards down to an underlying miniport driver such that TCP offload functions cannot be performed on the packets, the intermediate driver should respond to OID_TCP_TASK_OFFLOAD queries with a status of NDIS_STATUS_NOT_SUPPORTED instead of passing the request down to the underlying miniport." I dont understand what modification can it be ? For example IM driver that has implemented NAT. IP addresses and ports are changed, NdisSend() is called and miniport takes packet, calculates checksum and send it. I dont see any difficulty with calculating checksums by miniport on such NAT-ed packets. Or is there mean other type of modifications ? Peter Tag: Saving Device Parms to the registry Tag: 78003

    - How is WMI better I am trying to understand and use WMI for last two months. I am new to this. I am not able to convince myself why WMI is easier than directly talking to application or driver.

    - Dual SATA Disk Drive Issue Experiencing a problem with a SATA disks attached to a dual SATA disk Raid Controller. Posting here because it has happend with two different devices. Generating approximately 800,000 files and the entire machine locks up with insufficient resources error (0xc000009A). The files are generated as fast as possible, basically: do { name = getNewFilename() file = new File(name) file.write(data) file.close() } while(true) This did not happen while writing to a SATA drive attached via the mother board and controlled by the system bios. So given this has happened on two different controllers I was wondering if this is a problem with the class driver interface? System Configuration OS Version: Windows XP Pro Service Pack 2. CPU Type: Intel Pentium 4 3GHz (Intel Chipset 630) Memory: 1GByte DDR 400 Hard Drives: 3 X Western Digital Caviar 250GB SATA2 16MB (WDC WD1600JS-75NCB1) Transfer Type: SATA SATA Raid Controller: A-181 SiI 3x12 SATA PCI 2-Port Raid Card and Adaptec AStl-1205 SA 2pt SATA Both the SATA controllers above generate this problem repeatably.

    - When to use memory mapped io register? Hello all, I am a new device driver developer and hope that someone can help on the memory mapped io register. I am working on a new chipset which is recently supporting memory mapped io space feature. For earlier chipset, this feature was not available. To bad to say that my team members have not experienced in memory mapped io register. Therefore, we are not sure when to use memory mapped io register or read the io register from the pci config space instead. If someone can give some advices, that will be great. Thank you.

    - Registration Hi! I need to register a virtual serial port so that it can be enumerated with SetupAPI. As far as I understand, this can be achieved by exposing an interface towards the device using IoRegisterDeviceInterface. This function, however, fails for me. This is what I do: IoCreateDevice(DriverObject, sizeof(MY_EXTENSION), &Name FILE_DEVICE_SERIAL_PORT, 0, TRUE, &DeviceObject); // Check status etc IoRegisterDeviceInterface(DeviceObject, &GUID_CLASS_COMPORT, NULL, &ext->SymLinkName); This does not succeed, but instead returns status = 0xC0...10 (invalid PDO). What could cause this? The serial port works, i.e. it is possible to open, close, read, write etc, but the interface registration fails.

    - Capturing bits copied beyond primary display in a mirror driver Hi, I'm trying to mirror the output of a BitBlt executed in user mode at a position beyond the primary display (1024,0) in a mirror driver. The user application executes the following code: // initialize DEVMODE DEVMODE devmode; FillMemory(&devmode, sizeof(DEVMODE), 0); devmode.dmSize = sizeof(DEVMODE); devmode.dmFields = DM_BITSPERPEL | DM_PELSWIDTH | DM_PELSHEIGHT | DM_POSITION; devmode.dmBitsPerPel = 32; devmode.dmPelsWidth = 50; devmode.dmPelsHeight = 50; devmode.dmPosition.x = 1024; devmode.dmPosition.y = 0; // change display settings int code = ChangeDisplaySettingsEx(deviceName, &devmode, NULL, CDS_UPDATEREGISTRY, NULL); code = ChangeDisplaySettingsEx(deviceName, &devmode, NULL, 0, NULL); HDC hdc = CreateDC("DISPLAY", deviceName, NULL, NULL); // we should be hooked as layered at this point HDC hdc2 = CreateCompatibleDC(hdc); // call DrvCreateDeviceBitmap HBITMAP hbm = CreateCompatibleBitmap(hdc, 50, 50); SelectObject(hdc2, hbm); // blt 50x50 to destination 1024,0 BitBlt(hdc2, 0, 0, 50, 50, hdc, 1024, 0, SRCCOPY); Using WinDbg, I can verify that DrvBitBlt function (hooked in the kernel driver) was not being called in response to BitBlt. However, changing devmode.dmPosition.x to 0 resulted in the calls being routed to DrvBitBlt. Can anyone explain what is missing from the above code? Any suggestions are much appreciated.

    - Kernel mode to user mode communication Hi, I am developing a mini filter using the Microsoft IFS kit. My mini filter communicates with a user mode service which contains certain business logic. I have written the user mode service as a Windows NT service. The communication is done using the standard api's like FltCreateCommunicationPort, FilterConnectCommunicationPort, FilterSendMessage and FilterReplyMessage etc. Can the user mode service (not necessarily an NT service) be written in any other language such as Java? I mean, is it possible for the mini filter to communicate with a user mode service written in any other language then c++? Can the service written in other language such as Java, perl call the functions FilterConnectCommunicationPort, FilterReplyMessage etc.? Another approach could be that the user mode service written in Java can some how connect to the communication port created by the mini filter and read the raw data that is posted on it by the minifilter (assuming there is some standard format for the data posted by the Windows api's)? Is this feasible. (1st problem I face is I cannot connect to the port using its name '\\TestPort'). I would choose Java so that my application is portable across other OS, where I will just have to port the mini filter portion while the user mode application remains the same.

    - NDIS filter installation issue Hello, I have wrote a NDIS intermediate filter (NDIS 5.0) based on the passthru filter sample code, and I sometime run into an odd issue when installing the driver. The installation will be going fine (Windows asks me to confirm that I want to install that unsigned driver) and I can see the driver listed in the "Items list" of the computer network connection, but the driver doesn't work, it's driver entry function DriverEntry() isn't even called. This seems to occurs if I install/uninstall the driver a couple of times. If the computer is rebooted before re-installing the driver, it work fine. Thanks for any tips/advices.

Is there any recommended maximum size of data that can be saved to the
registry rather than saving to separte on disk file.

For instance for my device to work I might need 6K bytes of radio PHY
parameter data to program into the card.

Is it OK to save that much data to a single Binary Value under my parameter
key in the registry?

How about in multiple Binary Values?

thanks

IIRC REG_BINARY is up to 4MB or so (the limit possible raised in XP
timeframe)
