    - Do I have to pay special attention on receiving an udp datagram? Hello, I have to implement dns name resolution in kernel mode. My only problem is to receive an udp datagram. I can see that the datagram is send by the name server (with tcpdump) but I'am unable get it. I implemented in a similar way as James Antognini did in his tdi sample code <http://home.mindspring.com/~antognini/drivers/> except my isn't working. ;) At TdiBuildReceiveDatagram() I have the tdi ip address of the name server as ReceiveDatagramInfo and an empty tdi ip address as ReturnInfo. The ReceiveDatagramInfo is a pointer to the same ip address that I used to send the datagram and this works. I have double checked my code but I'am unable see the problem. So I have some questions: What does the transport with an udp datagram that is not taken by a tdi client? Will the transport delete such an datagram? Or is there a timeout before the transport will delete such a datagram? Is it a problem to have a slow machine? That the ReceiveDatagram() call might be to late and the datagram is already received by the transport and no client took it. I'am sorry if I ask stupid questions! -- h.wulff [dont send me an email] Tag: PCI Express Tag: 53486

    - handle leaks inside usb client driver Hello, I have a client usb driver which is built from bulk usb DDK sample . When some data is being sent to the driver ( through an ioctl ) , the Handle count of the user mode application talking to the driver keeps rising ( it keeps rising as long as we are sending data , for the amount of time no data is being sent , handle count remains stable ) The cause of the handle leakage has been isolated to be related to the driver . The GDI handles and User handles of the process however remain stable . I have seen through the code of the driver and there seems to be no explicit handle leakage . Any ideas on how to track this thing down? what could it most possibly be? I am opening the handle to the driver asynchronously from the user mode process , and all ioctls are passed an overlap structure , some of them i want to wait on so i also pass an event handle in the overlap str. and wait on them , for other ioctls i dont . I do not maintain any IRP queueing inside the driver however , since there is no particular type of IRP that i would possibly need more than once unprocessed inside the driver in a row. as a related question , the usb client driver's DLLs is not directly loaded into the address space of the user mode process talking to it ,and some Windows component ( IO / Pnp manager etc load the dll ) so why is it that the handle count is shown to be increasing in the task manager for user mode process for something that is apparently happening inside the driver? thanks and regards Taha Tag: PCI Express Tag: 53485

    - Phantom Interrupt Hi all, I have a PCI device that is displaying some strange behaviour, which I cannot seem to track down. When I put the machine into standby everything goes as normal and the machine ends up in its low power state. I then press the power button to bring it back up and I get the following: XP: My ISR gets called almost immediately and any of my calls to READ_PORT_UCHAR() result in a delayed response of 0xFF. When I say delayed, I mean it takes 20-25 PCI clock cycles as opposed to the normal 2. Inspection of the hardware shows that its not generating an interrupt. Inspection of the PCI bus shows there are no interrupts. 2K: ISR gets called a bit later than XP, calls to READ_PORT_UCHAR() result in valid responses, although there is still no real interrupt. Also, the phantom interrupt will occur randomly thereafter, sometimes in small bursts of 10-20. Now to finish everything off, the problem remains when using a different machine with same hardware, but disappears when moved to a completely different machine. For reference; I am experiencing the strange behaviour with a Dell Dimension L800r (I've used BIOS versions A09 and A14 with the same results). Has anyone ever run into something like this before? Thanks, Chris Tag: PCI Express Tag: 53477

    - DDK USBView sample bug There is a bug in the usbview DDK sample when they display the wMaxPacketSize information for high-speed isochronous and interrupt enpoints. In the current sample (3790.1218) the just display the wMaxPacketSize field. In the description of this field in the USB 2.0 spec, it says: For all endpoints, bits 10..0 specify the maximum packet size (in bytes). For hight-speed isochronous and interrupt endpoints, bits 12..11 specify the number of additional transaction opportunities per microframe. Since I do not know where to file DDK bug report I am posting this on this newsgroup. Olivier Lechenne Logitech Inc. Tag: PCI Express Tag: 53473

    - USB DATA Frame Synchronization I'm using interrupt endpoints to read data from my USB device. I appear to be having some problems related to maintaining the correct DATA0/DATA1 data frame synchronization between my device and the USBD. I've read the documentation and still am confused. So, my questions are: When, if ever, does the USBD reset the data frame for a particular endpoint back to DATA0? Can I (and is it ever wise to) force the USBD to reset an endpoint's data frame to DATA0? Thanks in advance for the help, Dennis Tag: PCI Express Tag: 53466

    - issue with DHCP discover and wireless Hi, I have a WPA client that works fine, receives the group key, no problem. If I use static IP I can connect to the Internet. But if I send a DHCP discover message (broadcast), I don't get a DHCP offer back. (I also never get a dhcp address) Now someone said I need to reset the Multicast list for this to work. I set the oid OID_802_3_MULTICAST_LIST with 0 but still I don't get any DHCP offer. I set this oid before I set ssid and those oids. any idea what I need to do? thanks! /Niklas Tag: PCI Express Tag: 53457

'Logitech' knows this problem on XP, and says on the site that it can do nothing ('Logitech' provides the user with the latest drivers, but it says that they don't solve the problem). - - - So, anyone who knows how to solve this?

    - drive verifier makes DMA impossible Dear all, Im writing a WDM driver for a PCI device doing bus master packed based DMA. The device and the driver are working well so far, until I followed the suggestion of some experts to turn on driver verifier. OK, I did that and ran into several problems (which actually was caused by my not so correct code). The most ones I could solve but there was one I couldn't get rid of: The DMA runs perfectly but the data are always 0x0E, no matter what was in my user buffer! The device is not "scatter/gather-able" so I split up the DMA transfer into several small one-page DMA transfers. The logical address determined by MapTransfer() seemed to be NOT describing my user buffer. When DMA checking of driver verifier is disabled the transfer works perfect and the logical address determined by MapTransfer() is higher (e.g. 0x0a2ed1f8), but I don't know if the address has anything to do with that problem. Thanks for help Daniel Tag: PCI Express Tag: 53439

    - WinXP PRO - UPS Minidriver Dll localisation bug ? Hi, I've written an UPS minidriver Dll. When running the Dll on an english version of Windows XP Pro everything works fine. According to the DDK documentation the battery status (HKLM\System\CurrentControlSet\Services\UPS\Status\BatteryStatus) has 3 documented states (0=unknown, 1=OK, 2=replace). Looking at the UPS status display (Start\Settings\Power Options\Power Options Properties\UPS) the display shows "Good" for state 1 and "Needs replacing" for state 2. When shutting down the system because of lost AC power a messenger service dialog box pops up saying "The UPS service is starting shut down at XXX". So far so good, the DDK documentation is consistent with the user display. Running the same Minidriver Dll on a german Windows XP shows a slightly different behaviour. The UPS status display shows "Niedrig" for state 1. This means "low" - a big difference to the documentation and the english version and confusing for the user because he thinks the batteries are low. The messenger service dialog box says "Der USV Dienst beginnt, wegen geringer Batteriespannung, bei XXX mit dem Herunterfahren." This means "The UPS service is starting shut down because of low battery voltage at XXX". This is also a big difference to the english version and confusing for the user because he thinks the batteries are low. The behaviour is the same with SP1 and SP2 of the german version. Now my question : is this just a bug in the german translation of XP or are there any other side effects (internal state etc.) ? Tag: PCI Express Tag: 53418

    - large block size under NTFS Hi I understand that the largest cluster/block size under NTFS is 64KB. I wonder how I can get around this and use a larger block size of , say, 2MB. In other words, each time when an application writes a large chunk of data, say 2MB, I want consecutive sectors be used. Can this be done with a filter driver on top of NTFS?

    - Printer drivers and StretchDIBits calls Hello I am writing a virtual printer driver for Win XP/2000. The driver is using an engine-managed surface and is hooking all next DDI functions: - DrvBitBlt - DrvStretchBlt - DrvTransparentBlt - DrvCopyBits - DrvAlphaBlend - DrvStretchBltROP - DrvPlgBlt All these functions are tested when printing from different applications, and they work fine. But when an application is printing a bitmap using StretchDIBits function, none of the above driver functions is called. Is StrechDIBits function writing directly on the driver surface bitmap, without calling any of Drv...() functions? Is there any way I can hook this function before it is writing the bitmap on the driver surface? Thanks Luminita Tag: PCI Express Tag: 53407

    - WinXP build environment I have installed (in this order): VC++ 6.0 Platform SDK February 2003 Windows 2000 DDK in my system (Windows XP SP1) for my build environment but it seems I messed it up.I cannot build the sample plotter driver. When I launch the checked build or free build utility, it says that there are some program or batch files that cannot be recognized. When I build the sample plotter driver, there is a U1073 error. plotlib.lib build method is not set, something like that. When I installed the SDK, I chose to automatically set the environment. Any idea on this. Thank you. Tag: PCI Express Tag: 53395

    - WDM NIC driver causes diabling of all network properties Hi All, I have a WDM driver for W2k/XP for a NIC this **IS NOT AN NDIS DRIVER** but a normal WDM driver that allows direct access to the NIC hardware. The hardware is a 3COM 3c90x on PCI. Once the driver is installed the user is not able to change any network settings for other installed network drivers (that do use NDIS drivers). The properties of other installed network drivers is disabled. The client has to uninstall the non-NDIS WDM driver to change the network setting and then re-install. Why is this and how can I prevent it? Cheers, SAB. Tag: PCI Express Tag: 53390

    - Dll Build I am trying to build a class installer dll and I want to use a .def file to specify the exported functions. After looking at the SDK and some DDK samples, I'm still a bit confused. How should I be building the dll: use the command line utility included with the SDK or the VC++ build enviroment? Is it just a matter of preference? I found a section in the MSDN library about how to use a .def file in the VC++ IDE, but was unable to locate the "project Property Page" to set the /DEF option. Can someone explain the steps needed to export functions in a dll using either the VC++ IDE or command line? Or point me to an article. Thank you for your time. Tag: PCI Express Tag: 53385

Is this a correct ? thankx Tag: PCI Express Tag: 53375

    - hooked functions in usermode printer driver I have a monolithic usermode printer driver (see my numerous previous question for details :) under development. It's adapted from an earlier kernel-mode printer driver. I'm trying to work out the final kinks, and I've come across some rather odd behavior. I've found that some applications have trouble printing particular shapes (diagonal lines and ellipsesfor example) on any page except the first. In the kernel-mode driver, these work fine, and in the debug output I can see calls to DrvBitBlt for each of these shapes that is drawn on the printed image. In user-mode, I don't see these calls. In fact, I don't see any of my driver code being called. Somehow these shapes make it onto the first page I print, but never the second. I am hooking DrvBitBlt, DrvCopyBits, DrvStretchBlt, DrvTextOut, DrvFillPath, DrvStrokePath, DrvStrokeAndFillPath, and DrvLineTo. How would the application get data onto the driver's surfaces? -- Matt Kane mkane@zebra.camel.com minus cigarettes Tag: PCI Express Tag: 53373

    - WDM driver and services What are the things that one needs to consider when interacting with a user mode component( say with a service EXE) from a WDM streaming driver. Basically, the service si started before the logon and it makes an IOCTL to the driver with the necessary data. It also wants to create an Event that the driver would call whenever it needs data and waits on the event so that when the event is triggered, it does an IOCTL(KssyncrhroniseDeviceControl through a cutom property set) and then goes back into Wait mode for the event to signal. How would this be done ? Just implementing a pending IRP wont do as there are no IRP's, but SRB's and the WMD streaming driver would only interact with the Stream Class driver. Does, the WDM driver need to implement EVENT_SETS(I guess not) ? Because, in this case, the service can Create an Event and send that event handle to the WDM driver and wait on it to get into signalled state ? so if thats the right approach, what does the WDM streaming driver need to do to handle this scenario and signal the event, whenever it needs some data. Thanks. Tag: PCI Express Tag: 53369

    - Device CoInstaller Hello, Following the toaster example in the Windows XP DDK, I have been able to make a device co-installer and have had my inf file register it properly. I am handling the DIF_ADDPROPERTYPAGE_ADVANCED event, but am unable to get my property page to show up. If I make it a class installer, I can get the page to show up (this is the specific example in the DDK, whereas I want to have it device specific). I get no errors, and everything seems to be as the DDK describes, but the page simply does not show up. Am I having the page get added to the wrong device instance (though I only have 1 enumerated)? Does anyone have any additional examples where this is being done for a device co-installer? Thanks, Abe Krebs Tag: PCI Express Tag: 53363

    - how to notify? Hello all, From time to time I want to send some data from NDIS driver to user-mode application. How can I do it? The first thing that comes up to my mind is to create a device with NdisMRegisterDevice and query it in a loop from user-mode program. But this will take some processor resources... Are there any other ways to receive notifications from driver? What I need is a two-way pipe between driver and user-mode application. Thanks. Best regards, Serge. Tag: PCI Express Tag: 53362

    - Question on porting the USB driver from Windows 2000 to Windows 98 Hoi, I have a USB driver like this(quoted from the driver user guide, a little bit complicated): --------------------------------------------------------------- The USB host driver runs on Windows 2000 and Windows XP platforms. It simulates two types of legacy functions or devices over USB: modem and serial port. The driver accepts the following: * Single-function device â?? includes the USB modem and the simulated legacy serial port device * Composite device â?? consists of a logical modem and a logical serial port device Although the driver is designed to work with the device compliant to USB CDC 1.1 Abstract Control Model (ACM), it accepts standard USB CDC ACM descriptors as well as AAA vendor-specific descriptors. (here, AAA stands for the company name) --------------------------------------------------------------- Do you think it can be ported to Windows 98 SE without major changes(e.g., have to change the driver model from WDM to VxD)? If yes, modify the existing driver source code so that it could be compiled under 98DDK successfully, or use Walter Oney's WDMSTUB technique? which method is possible and easier?

I found that the disk drive will be automatically assigned if I set the RMB(Removable Medium Bit) in the SCSI Inquiry just like the USB card reader.
