    - How to use solid RGB colours in a printer driver Help, I am working now for weeks on this vector CGM printer driver and I become more and more confused how I am supposed to get RGB colours. I tried to make sense out of the HPGL msplot example vector driver, but I don't understand the relationship anymore between brushes and solid colours. If my device supports 24bits colours, do I still need to create some kind of bitmap pattern just to draw for example a red line? (My virtual device can handle 24bits RGB colours.)

    - IOemUni::ImageProcessing problem Hi. I am implementing a bitmap printer driver using oemuni sample in NTDDK. My problem is... When I print a document, some(it could be one or more) garbage bitmaps are generated in ImageProcessing. I just dumped the pSrcBitmap data to a bitmap file in ImageProcessing. I think I can get a printed bitmap image by merging all band images. But there is a problem in my driver. As I mensioned above there are some garbage band images. For example... During one page is printed through my driver, the page devided into 5 bands and I saved each band. When I checked the saved iamges after printing is finished the last image is a garbage image. It has any portion of the document. But the portion has already been included in previous band image. So to get a perfect bitmap I should merge the first four images in this case. But I think there is no way to find out what image is garbage. I think the number of bands is sensitive to or dependent on the GPD. But I don't know where should I change to solve this problem. If there is no garbage image every printing job, all I have to do to get an image is to merge all band images. Anyone has good idea to solve my problem?

    - DrvEnablePDEV is called more than DrvDisablePDEV Hi Going through my driver, I noticed that DrvEnablePDEV is called more often than DrvDisablePDEV in a printjob' The docs say I should allocate resources for PDEV in DrvEnablePDEV, and deallocate in DrvDisablePDEV, but this way I get a memory leak BTW, the driver seems to work !!! Any help on this ? TIA LB Tag: DIFxApp error codes Tag: 50403

    - RNDIS question Hi all , I am working on RNDIS device now and have a couple of questions on this regard : 1. There are two fields in the REMOTE_NDIS_QUERY_MSG { InformationBufferLength, InformationBufferOffset } . Those fields indicate where the params for the specific query are located in the transfer . The question is : where can I get a list of the structs which are passed for each query ? I have searched in the MSDN and DDK information , but nothing . For example , for the OID_GEN_LINK_SPEED I see that the host passes some params - but I dont know what they are . 2. I have noticed that params for the same query are different between 2K and XP . For example , for the same OID_GEN_LINK_SPEED 2K sends 4 bytes while XP sends about 40 . Does anyone know what is the deal there ? Why is the difference ? Where can I see the list of differences ? thanks a lot Oleg Tag: DIFxApp error codes Tag: 50402

    - IoGetDeviceObjectPointer on serial driver !! Hi The first time I call IoGetDeviceObjectPointer on \Device\Serial0 the function call do not fail. Any attempts to open the COM port from user mode app. fails, which is fine. But when I stop the driver i stil can't open the COM port from a user mode app. ?? In my DriverUnload function I do call ObDereferenceObject() on the fileobject returned by IoGetDeviceObjectPointer. Any further attempts to call IoGetDeviceObjectPointer on \Device\Serial0 fails, (with error code 3221225506) which according to the DDK help files, can't be returned ? Isn't IoGetDeviceObjectPointer a combination of ZwCreateFile, ObReferenceObjectByHandle, IoGetRelatedDeviceObject, ZwClose ?? So why can't I reopen the COM port ??

    - 1394 devices: Bus reset while processing SRB_INITIALIZE_DEVICE ! Hello list! I am still working on the issue that my drivers fail to communicate with a IEEE1394 ( firewire ) device on device initialization. This is what I see: The driver gets an SRB_INITIALIZE_DEVICE request. While this happens, another bus reset is happening on the IEEE-1394 bus which changes the generation count. Now the driver tries to access the device to initalize the drivers structures and the device state BUT every register access fails due to "STATUS_INVALID_GENERATION". According to MSDN, the driver should now request the current generation count using the REQUEST_GET_GENERATION_COUNT bus request BUT it should not use this generation count unless the next Bus Reset Notification is recevied by the driver. And in fact, it is not possible to do a single register access while processing the SRB_INITIALIZE_DEVICE request from now on. So what am I supposed to do in this situation? If I fail the SRB_INITIALIZE_DEVICE request with STATUS_IO_DEVICE_ERROR, the driver gets unloaded for the device and is not accessible at all. If I succeed the SRB_INITIALIZE_DEVICE in the hope that I get the Bus Reset Notification afterwards to update the generation count and finish the initialization in SRB_INITIALIZATION_COMPLETE also does not work because SRB_INITIALIZATION_COMPLETE is called first and the Bus Reset Notification is called later on. Worst of all, this behaviour is completely reproducable on my system since I installed the Service Pack 2 for windows XP! If I uninstall the service pack, I do not get multiple bus resets when connecting the device ( at least I do not get a bus reset while processing SRB_INITIALIZE_DEVICE ) anymore and everything works fine. I am completely stuck. I fear, this one is going to cause BIG TROUBLE!!! -Arne Tag: DIFxApp error codes Tag: 50398

    - How to get the indication in protocol driver? Hello, I have written an protocol driver (Modifid from DDK sample code, Ndisprot). I found that if the service "QoS packet Scheduler" is enabled, then my protocol driver can't receive the indication in ProtocolStatus(). But if I disable the service "QoS packet Scheduler", then my protocol driver can receive the indication. How can my protocol driver receives the indication and the service "QoS packet Scheduler" is enabled? Best Regards, Ivan Tag: DIFxApp error codes Tag: 50395

    - Wireless Provisioning Services (WPS) documentation now available ------=_NextPart_0001_4280AB10 Content-Type: text/plain Content-Transfer-Encoding: 7bit See http://www.microsoft.com/whdc/device/network/wireless/wps.mspx. Wireless Provisioning Services Updated: August 18, 2004 Wireless Provisioning Services (WPS) enable the discovery of and connection to wireless networks. WPS enhancements are included in Microsoft Windows XP Service Pack 2 (SP2) and under consideration for Windows Server? 2003 Service Pack 1 (SP1). WPS extends the wireless client software included with Windows XP and the Internet Authentication Service (IAS) included with Windows Server 2003 to allow for a consistent and automated configuration process when connecting to public wireless hotspots or private wireless networks that provide guest access to the Internet. The WPS APIs allow for the pre-provisioning of network information to connect to these networks and the provisioning of network settings to connect to private wireless networks.

    - SCSI SRB FLAG does not make sense - SRB_FLAGS_NO_DATA_TRANSFER Hello everyone, In the DDK, page SCSI_REQUEST_BLOCK (System Support for Buses->SCSI Bus->Reference->SCSI Bus Structure->SCSI_REQUEST_BLOCK), the SrbFlags can have a flag set as 'SRB_FLAGS_NO_DATA_TRANSFER'. The page says, "Indicates no data transfer with this request. If this is set, the flags SRB_FLAGS_DATA_OUT, SRB_FLAGS_DATA_IN, and SRB_FLAGS_UNSPECIFIED_DIRECTION are clear" Now when I look at the include file srb.h, this flag is '#define'd as 0x00000000. Can anyone explain this? If I am going to test the flag using the following statement: if( srb->SrbFlags & SRB_FLAGS_NO_DATA_TRANSFER ) { // do all this } I will never have the block executed. This got to be a bug, true or not? Thanks. Tag: DIFxApp error codes Tag: 50372

    - microsoft os descriptor (usb) Can anyone help me locate the information on how to implement the Microsoft OS descriptor in a USB device? I found some "os descriptor" defines and structs in the 2003 DDK which, when returned by my device does seem to make WinXP SP2 to query for more information. However, I have not found (ddk help, microsoft.com, google, etc.) any documentation whatsoever on how to correctly/fully implement this. http://www.microsoft.com/whdc/system/bus/usb/USBFAQ_intermed.mspx <quote> The Microsoft OS descriptor is a set of data structures that IHVs can use to include extra information in device firmware, information that Microsoft OS descriptor-enabled applications and operating systems can extract. The data is extracted by vendor-specific USB requests to the device as indicated in the OS Descriptor specification.

    - USB port monitor error 1223 Hi there, I'm working on a custom language monitor for a USB printer. I've found that if the printer is unplugged then plugged back in, any WritePort calls to the USB port monitor result in failure with an error 1223. Obviously I can't write to the printer while it's unplugged :) but once it's plugged back in, is there anything I can do to get the port talking again? If I delete the job that is failing, the next one writes to the printer without a problem. -- Matt Kane mkane@zebra.com Tag: DIFxApp error codes Tag: 50358

    - IRQ Sharing causes multi-function adapter to lock PC We are having problems with a third party vendors card. Everytime it shares an IRQ with another PC device, it locks the controller. We've been able to recreate and fix the symptoms by freeing up the sharing IRQ resource. The vendor is trying to integrate a LSI mulitfunction chip that passes about 120MB/s (yes, 120 Mega Bytes per second) on the PCI bus. This is near the theroetical bandwidth of the PCI bus. One caveat that we have is that for stability purposes, we have to use the "Standard PC" HAL instead of one of the ACPI HAL's available with XP/2K. This is for compatibility purposes with legacy devices integrated into our product. Our ultimate goal is to get the device to share an IRQ. We aren't going to rewrite their driver. Are there any BIOS settings or OS fixes that might help to let this device share an IRQ? Any suggestions? Anyone? Thanks. Tag: DIFxApp error codes Tag: 50354

    - Listing files that comprise a display driver Hi, One of my current tasks is to list out all the files that comprise a display driver, and the final piece of code should work on both WinXP and Win2000. I have written a piece of code that will list out the files of a driver, given the driver inf file, and the device id. Now my task is to figure out the inf file of the display driver installed on the system. When I use EnumDisplayDevices, the field DeviceKey gives me some information about a location in the registry to the driver registry area within HKLM\SYSTEM\CurrentControlSet. Would like to know if I could and if yes, how, could I use the information in the DeviceKey to get to the inf file of the driver... Can anyone help?? Thanks, Radha.

I've read that "Except on Win 98 and Millennium, file and print sharing must be active" How can my install program ensure this (programmatically)?

    - VFW Streaming Transfer under WME Hi, I have port a 32bit, user-mode only VFW driver from bravodo sample to an user-mode only Video Capture Driver. I understand that VFW using two transfer mode - Frame (Single Capture) and Stream. For eg, Dorgem, use Frame (Single Capture), However, AMCAP and WME seem use Stream (WDM based). My only problem now remain is on STREAM transfer mode Cause it quite long, in summarized, I used as follow : on DVM_STREAM_PREPAREHEADER - return DV_ERR_NOTSUPPORTED, so suppose client will supply the buffer on DVM_STREAM_ADDBUFFER - add into queue, return DV_ERR_OK When the data ready, I use DriverCallback (with MM_DRVM_DATA). But however, the data seem not pass-through client driver, the preview and/or output screen show nothing, and the WME FPS (Frame per Seconds) show zeros, but show encoding... and my debug show DVM_STREADM_PREPAREHEADER, then DVM_STREAM_ADDBUFFER repeated for about 40 times, then my driver fill the buffer and callback, and this repeat. FYI, I'm using separate thread procedure to supply the data into VHdr (buffer queue), synchronized through semaphore (replace STI/CLI for H/W board), and notify client with DriverCallback (MM_DRVM_DATA etc). I understand that WME, AMCAP etc use somekind of VFW wrapper for WDM, How do I verify that my Callback worked ? Any recommend for a sample WDM client with source-code for me to easy debug (for,eg, the callback did called correctly) ? Thank in advance wp Tag: DIFxApp error codes Tag: 50348

For getting quick results about feasability, I used libusb-win32 (latest version). I tried to reset the device, enumerate all for getting a new handle set config but got an error.

    - problem using a standalone device object with NDIS Hello, I have a problem when using 'NdisMRegisterDevice()' in my NDIS driver. I use this call to create a standalone device object so that my application can communicate with my driver. Using this, I can communicate with my driver fine from my app. However, the file handle that my application creates to talk to my driver does NOT get notified when I register to receive device notifications using 'RegisterDeviceNotification'. However, if I create a handle using the REAL device name (obtained by using the SetupDixxx functions), my app properly receives the notifications. I can't use this handle tho', 'cuz NDIS owns it and my driver won't received Irps sent to it. The basic problem I'm trying to solve is this: if the device is unplugged WHILE the app is running, the app needs to close the handle to allow the driver to unload.

    - Getting quick IP address on P2P RNDIS network There is a small problem that we've run into, which I hope somebody can help us with. We have a USB device, which supports RNDIS and that causes an XP machine to create a separate network for it. The device also creates a "remote" node on that network essensially establishing point-to-point network inside the device itself. Now to the problem, how do we quickly assign IP address to this network? I am looking for any suggestions - from totally legal to semi-legal. So far this device is restricted to a lab environment, but having fully supported solution is obviously preferred. Static IP assignment is out of question. So is auto IP as it is too slow. We need to be able to assign a address in a matter of seconds or even faster. Also a requirement - multiple instances of this device can be connected to the same machine and they all have to sit on separate networks and don't conflict with each other. The only solution that I can think of at a moment is to have the device being a DHCP server for its own net. Problem: multiple devices can be connected to the PC and there must be a solid algorithm in place to avoid any conflicts. I was also told that IPv6 would solve this issue. This is very generic problem and I am sure there are good solutions to it. Can anybody offers any suggestions or refer me to relevant RFC or something? Any help would be appreciated. Thanks! -- Max.

    - DIFx Framework - HOWTO Hi All, First, I have only a basic understanding of the certificates, signing, etc. so please excuse me if some question appears to be a stupid one :-) I'm evaluating the MS DIFx framework as to make a single file installation of the driver I've made. In connection with this I have tried to set-up an installation through DIFx framework but have some troubles with it. I get the following error in DpInst.log file for every INF file in the driver: "ERROR: driver package 'drive:\path\INFFILE.INF' is unsigned. Error code 0x800B0100, No signature was present in the subject." Could somebody explain me what is the right way to set-up the installation. - As far as I know only the cat file should be signed not all the files in the driver package... Follows a short description of how I've tried to make the installation: In the INF file I have included the requested CatalogFile and DriverPackageType sections: CatalogFile=CBMA.cat DriverPackageType=PlugAndPlay The content of CBMA.cdf file is: [CatalogHeader] name=CBMA.cat [CatalogFiles] CBM.dll=CBM.dll OEMUI.dll=OEMUI.dll OEMUNI.dll=OEMUNI.dll CBM.ini=CBM.ini CBM_CT1000II.INF=CBM_CT1000II.INF CBM_CTS300.INF=CBM_CTS300.INF CBM_PPU700.INF=CBM_PPU700.INF CBM1000II.GPD=CBM1000II.GPD CTS300.GPD=CTS300.GPD PPU700.GPD=PPU700.GPD ttfsub.GPD=ttfsub.GPD CBMA.HLP=CBMA.HLP eula.txt=eula.txt From this file I have successfully created .cat file and subsequently signed it with a test certificate obtained through makecert.exe and cert2spc.exe... After that I copied DpInst.exe in the driver directory and made eula.txt and dpinst.xml files. Subsequently when I ran DpInst.exe I received the described error.

I know Windows queries the Ndis driver using OID_GEN_LINK_SPEED, which is supposed to return the max Tx rate. In a wireless network, the max rate is determined by the Service Set. Therefore, I would assume that when associating with a particular Access Point, I should always get the same link speed. However, I've seen cases where the link speed changes between 1, 2, 5.5 & 11Mbps - even though I'm still connected (i.e. no disassociation/reassociation occurs). My service set consists of a single Access Point, which is configured to use all 4 rates (i.e. they're all marked Mandatory in the beacon parameter set).
