    - MultiOS Printer INF and Internationalization I can't seem to get the (MultiOS-based) INF that installs correctly on 2000, XP and 2003 to load "additional drivers" for 2000/XP/2003 for Point and Print on the 2003 machine. It keeps saying: "The selected driver must be installed remotely from an x86 computer running Windows 2000, Windows XP or Windows Server 2003." Then I thought that because the drivers are in .\English\i386, .\Chinese\amd64, etc., it would need to know the locale of the remote client to set LANGFOLDER= properly to locate the correct driver (and since it can't, it doesn't). So, I changed %LANGFOLDER% to ENGLISH, but did not help. Then I found http://whidbey.msdn.microsoft.com/library/default.asp?url=/library/en-us/ins tall/hh/install/create-inf_7l9j.asp ... anyone know for a fact that I am on the right or wrong track?!? Is it just plain impossible to support Point and Print with Internationalized INFs? Tag: forceIfDriverIsNotBetter DPInst Tag: 57759

    - USB Reset I am writing a driver for a usb device that contains a hardware watchdog. At this time, as well as during firmware updates, the device can be reset. The PC then shows the device (using usbview) as failing enumeration and of course my driver is unloaded. If I try to reset the device using devcon restart usb* I get the "requires reboot" message next to my device. But then it sometimes works anyway? I'm thinking that I need IOCTL_INTERNAL_USB_RESET_PORT but I can't quite figure out where to use it. My driver is unloading, do I send it on the way down? Or do I then do it on the driver restarting and I still need the devcon functionality. thanks Tag: forceIfDriverIsNotBetter DPInst Tag: 57756

    - how to detect "turn off monitor" activation? hi i want to know in my application whenever the monitor goes to power off or power on state because of the expiration of inactivity in the monitor due to the following setting: Display Properties -> Screen Saver -> Power -> Power Schemes Tab -> Turn Off Monitor Currently i am doing it the hard way , i.e. adding escape codes in my display driver that in turn talk to the video miniport driver through IoControl . first my user mode app creates an event and sends event to the miniport this way. whenever miniport driver gets power change status from vidoeport.sys it sets the user mode event at whicch the app would query its value thru another escape code in a similar way. Given the complicated method of getting a simple piece of information , i am forced to think there might be an easier way of doing the same , some API or any other simpler method is there any? thanks in advance Taha Tag: forceIfDriverIsNotBetter DPInst Tag: 57755

    - IEEE1394 & XP SP2 Incompatibility Hi, We are manufacturers of a 1394 based flash memory card reader. It is presented to Windows as a generic SBP2 device and as such, uses the standard Windows 1394 SBP2 device drivers. The reader is currently being shipped and works well with Windows XP SP 1/1a and Windows 2000 SP4. However, with Windows XP SP2, our embedded 1394 software stack crashes during the initial startup phase. Windows XP continues to run, but the device is not detected. We have tried different 1394 PCI host controllers without seing any difference. Our device presents itself to Windows as a single LUN with 6 Management Agents, one for each media type. We use a 1394 software protocol stack running in VxWorks on a Toshiba TMR3927 microcontroller. We have used a 1394 CATC hardware bus analyser to capture and compare the traffic between the PC and our device under XP SP1a and XP SP2. With XP SP1a we see a bus reset followed by logons to each of the 6 Management Agents. With XP SP2 the above also happens but is followed by another bus reset followed quickly by 6 reconnects to each of the Management Agents. Shortly after this things start to go badly wrong. The 1394 bus topology following enumeration after each reset is different. Our suspicion is that there is not enough time for our software to recover from the second bus reset before Windows starts communications with the new configuration. What is the purpose of the second bus reset? Is it necessary? This is only a theory; from the embedded device side of the bus, we see multiple errors and eventually a total system crash. The errors are not repeatable and vary from test to test. The symptoms would suggest that we are being overloaded with unexpected events and can't keep up. Keep in mind that we are running a relatively slow software protocol stack and need time to respond. Any advice/suggestions/explanations ?

    - ZwCreateFile create directory question I want to only open a directory to read its security settings. I am of course in kernel mode , and I would assume then that I'd be allowed to do whatever I might want. Status = ZwCreateFile(&FileHandle, GENERIC_READ|GENERIC_WRITE, &ObjAttrs, &StatusBlock, 0, //allocation size FILE_ATTRIBUTE_NORMAL, FILE_SHARE_WRITE|FILE_SHARE_READ, //share access FILE_OPEN_IF, // disposition FILE_DIRECTORY_FILE, // CreateOptions, 0, // EaBuffer OPTIONAL, 0); In many cases this code works, but if the directory has any security settings, then I've gotten status_access_denied as the status. I've made this code work by changing the desired access to GENERIC_READ rather than GENERIC_READ|GENERIC_WRITE. So my question: If I'm in kernel mode, how come I'm being prohibited from opening the directory with GENERIC_WRITE access? -- Gak - Finecats Tag: forceIfDriverIsNotBetter DPInst Tag: 57704

    - NDIS - asymmetric link speed Dear NDIS gurus, Now I have adapter with asymmetric send/receive speed ( uplink speed about 1/3... 1/4 of downlink). The media type is ethernet (generic or, possibly, 802.11 emulated). How TCPIP relies on link speed value reported by driver? which link speed the driver should report? And same question, if the device does throttling and prioritizing - the actual link speed is different for different payload types. The marketing, sure enough, wants to display the biggest speed value... Thanks, Pavel Tag: forceIfDriverIsNotBetter DPInst Tag: 57703

    - How to get USB Printer Serial Number I am writing an application which needs to retrieve the USB Serial Number from a printer connected to the system. I have access to the Printer Queue name, and hence I also know which USB00x port (generated by USBPRINT.DLL) that it is connected to. What is the best strategy to use to get the printer's serial number? Would there be any difference in this strategy depending on whether the OS is Win98, Me, 2K, or XP?

    - BITSPIXEL bug in Postscript drivers It looks to me as if GetDeviceCaps(hdc, BITSPIXEL) always returns 1 if the driver is the Microsoft Postscript Printer Driver (Pscript, implemented in pscript5.dll).

Am I doing something wrong? Is there an alternate way to determine the color depth supported by a printer? Nolan Tag: forceIfDriverIsNotBetter DPInst Tag: 57657

    - Route table for dialups Hi, Our company is developing an intermediate filter driver implementing Mobile IP. There is one virtual adapter (called "Home adapter") in the system that serves as Mobile IP tunnel entry point and all packets sent to it are encapsulated into MobileIP tunnel and sent using filter driver to one of physical adapters. All packets that are sent to physical adapters from windows are blocked by filter. In order to get it work correctly windows tcpip must route all packets to Home adapter. Its not hard to do it if there are only connection-less adapters, but when there is dialup connection dialed we have a problem. No matter how the connection has "use default gateway" flag set - tcpip always adds a routing rule for this connection the only difference is whether its mask is 0.0.0.0 or 255.0.0.0. We need to delete this rule every time the connection is dialed. It works but not everywhere. It seems that Windows XP SP1 machines have problem with the deletion of such rules. "route delete" command that works on SP2 does not work on SP1. Is it some bug in tcpip or route table ? Or is there any (other) way how to get rid of that nasty rule ? thanks in forward -- Martin Stangel, Technology Research and Consulting Whitestein Technologies AG Pestalozzistrasse 24, 8032 Zurich, Switzerland URL: www.whitestein.com, Phone: + 41 44 256 5016, Fax: + 41 44 256 5001 Tag: forceIfDriverIsNotBetter DPInst Tag: 57656

    - Reasonable to put the encryption module for an encrypted filesystem driver outside the kernel? Hello, from my point of view I would put the encryption module (which belongs close to the file system driver) inside the kernel. On the other hand I could mention that encryption is not a task for a kernel and therefore I should put the encryption module outside kernel. May I ask for your option?

    - XP USB driver stack/lost bytes on bulk transfer Hello I loose bytes ( some multiple of 64 bytes ( =MaxPacketSize ) ) with Windows XP SP1 on a Gibabyte PC 566 MHz ( single CPU ) with a VIA chipset ( USB 1.1 HC ). The following happens: My USB device driver sends 'read' urbs down the stack ( reading a picture ~1.5MB from scanner ). USBD_SHORT_TRANSFER_OK ist set and MaximumTransferSize ist default ( 4KB ). If i read the image with urb->UrbBulkOrInterruptTransfer.TransferBufferLength=64 bytes, some 64 byte-packets get lost in lower drivers. When TransferBufferLength is set on some higher value ( multiple of 64 ) the image is transfered correctly. Tests: Tested some ( faster ) ASUS pcs with Intel chipset -> No problems. Downloaded and installed the latest USB hotfix -> No changes. Wrote a filter driver 'lower' my driver -> Yes, bytes get lost when requesting 64 bytes. Wrote a 'HC debug driver' permanent checking the HC registers -> HC never reports errors ( did not check transfer descriptors ). Counted bytes on USB analyzer -> The whole image is transferred. Activated debug outputs in my driver -> OK, also when TransferBufferLength=64! Changed internal flowings in my usb driver to be faster -> Bytes get lost on TransferBufferLength=64 AND TransferBufferLength=128 ( OK, on higher values )! Tested my own NT and OS/2 drivers on that motherboard ( the image is transferred twice faster than under XP ) -> OK. Used checked build versions of the XP usb drivers -> did not see any errors reported in windbg, but i'm not very experienced in that. I know, that VIA has ( maybe had? ) some special 'features' implemented in USB ( in contrast to Intel ), but for me it looks like a bug in the XP USB driver stack; maybe some 'timing issue' ( the faster the usb device driver, the more bytes it must request each urb!? ). Any ideas? Thank you, Bernhard Ruhsam PS: The reason, why i have to request just 64 bytes is, that there's a bug in the firmware of the scanner, which does not send zero length packets.

    - Printer driver-newbie question Hi, This forum is way beyond a question such as this, but here goes: First, I should state that I don't know jack about networking. Anyway, if I develop a printer driver for XP, most likely using the Unidriver approach...and it works fine as a local printer, can I also expect it to work on a network? In other words, is a network printer driver different than a local printer driver? The printer has a serial or USB interface, not ethernet.

    - XP SP2 WDM driver - Sharing Memory between driver and application : Hi all, I have to confess... I'm almost translating my application from Windows to Linux just because I can't make a WDM driver for my PCI card... Help me, please! I have a motion control PCI card that can command 2 motors. That card generate interrupts. I have an application and an old driver (VxD) working very well with Windows 98 SE, but now I'm trying to make a WDM driver for Windows XP Professional SP2 because Microsoft is not selling Win98 anymore. In my new WDM driver, the communication with the PCI card from the driver and from the application (I pass an address from the driver to the application, so the app can communicate directly with the card) is tested and working fine. The interrupt service routine (ISR) is working very weel too. The only big problem is that I need to share 10 buffers between the driver and the user app (velocity, aceleration, etc). Those buffers can't be swaped to the disk and some of then are 1MB length, and one is 9MB lentgth. They are filled with velocity, aceleration and other information by the application, and the driver fill some buffers with other kind of information. My PCI card has no memory, so I have to make use of "user buffers" (created in the app) or "system buffers" (created in the driver). The most important thing is that those buffers MUST be used (read & write) inside the ISR, at any moment, as weel as the buffers MUST be accessed (read & write) from the user app at any time (of course, not when the driver is inside the ISR). The app must be running all the time because it needs to get events from the user to communicate the driver to start or stop listening to interrupts, so it seems to me that I can't return STATUS_PENDING with METHOD_DIRECT (can I?). And the two big questions are: 1. Is that realy possible? (Are you sure?) 2. How? I've been reading all the posts about this subject from all lists and years, since Jan.2004 to this day, and I couldn't find a way to get that driver working ok. I also have the Viscarola & Mason "Windows NT Device Driver Development" book... Good help, but couldn't sove the problem. Can you help me? Thanks a lot. Paulo.

    - IoConnectInterrupt Continued... From the DDK documentation, title "Registering an Isr": To register an ISR, a driver's DispatchPnP routine must call IoConnectInterrupt when it receives an IRP_MN_START_DEVICE request. In response, the I/O Manager creates an interrupt object for each processor that the device can interrupt. In a previous thread, I had gotten several suggestions about which parameter to IoConnectInterrupt was causing it to fail with STATUS_INVALID_PARAMETER, but none of them helped. The code worked OK on single processor systems. If the affinity argument (extracted from the translated resource list in the start device IRP) indicates that more than one processor can be interrupted, how does the I/O manager return a pointer to multiple interrupt objects? Is there some special coding to connect an interrupt on a multi-processor machine? The DDK documentation seems to have little to say about this. Tag: forceIfDriverIsNotBetter DPInst Tag: 57579

    - UNIDRV IOemUni::ImageProcessing Question I am confused about how to use the bBlankBand variable in the ImageProcessing function. When the print driver is banding, bBlankBand will be 1 for the first band and then 0 for the remaining bands. The documentation says that if it is 0 then the data is invalid. But I never receive any further calls to ImagePricessing with bBlankBand set to 1. As a result I only get the top portion of the image. Do I have to do something else to get the remaining bands rendered? I am using the oemdll example in the DDK. When the driver is not banding then I get the whole image in one shot but higher DPI's force me to deal with banding in ImageProcessing which I can't seem to get to function correctly.

    - Windows Update causing problems with Cypress FX2 development board Hi all, I would like to warn the Windows Cypress FX2 USB development community about and bring to Microsoft's attention a very annoying problem that I had this morning. I plugged in my Cypress FX2 development board (CY3681) and Windows went searching for drivers for it, because between today and the last time I used the board I had uninstalled the USB 2.0 host controller in order to force renumeration of previously-installed USB devices on my system the next time I plug them in. (This is something I do from time to time during development to make sure that my development devices enumerate properly.) Anyway, Windows found the proper .INF file and installed the correct driver... then promptly went ahead and installed a DIFFERENT driver, one for a 'Sperling USB HDTV' device! I assure you I have never installed any USB HDTV drivers on my system. Ever. I went looking through the .INF files and found an entry in one of the oem##.inf files (in my case oem18.inf) there was an entry with the SAME VID and PID as the development board! It looks like some hardware developer was building a prototype with the FX2 sans EEPROM and let the development board's VID and PID slip into the .INF file. I removed the offending entry from the .INF file, did the aforementioned uninstall trick on the USB Host Controller, plugged in my development board, and got the SAME RESULTS. This time, however, the offending entry had been written to a brand-new .INF file. I tried removing the .INF file altogether the second time and the same thing happened. Many different combinations caused the same thing to happen. Whatever I tried to do to force that entry to be gone was undone. I had a colleague look at it and he suggested that it might be picking up the information from Windows Update. So I unplugged my network cable, uninstalled the USB Host Controller again, and plugged in my FX2 board, and it worked. I am not really familiar with what happens with Windows Update behind the scenes. I would first of all like to know what was happening, if in fact the .INF file entry was getting picked up from Windows Update, and, if so, if there's a way to prevent this in the future. (I have auto-updates turned off, but I know my company pushes periodic updates to my machine.) Secondly, it seems very bad to me thata vendor is shipping an .INF file with the same VID and PID as another device from another vendor. For reference, the entry appeared on my machine in oem18.inf. The first few lines of the file mention USBHDTV.INF and 'This file contins installation information for OnAir USB HDTV, An MPEG2 WDM capture driver that requires hardware'.

    - HID Joysticks and Win98 I wrote a WDM HID minidriver to create a virtual joystick. Problem is that the joystick does not show up in the game controller control panel app of Windows 98. The device manager, however, shows the HID-compliant game controller device create by my driver. Since it works fine in Windows Me/2000/XP, I suspect that my HID report descriptor cannot be parsed by Windows 98 (I noticed that the WinMe implementation is somewhat picky in that regards, whereas 2000/XP takes about anything), but I am not positive on that. I wonder if somebody has a working report descriptor (joystick or other type of game controller that shows up in the control panel app) that is known to work with Windows 98 and is willing to share. I tried already many different variations, but no fun yet. Also, any hints on that topic would be greatly appreciated. Karl Tag: forceIfDriverIsNotBetter DPInst Tag: 57486

    - Blocking PCMCIA, SCSI and IDE storage devices Dear All, I need to block all mass storage devices that can be connected to PCMCIA, SCSI and IDE slots. My current plan is to write 3 class filter drivers to PCMCIA, SCSI and IDE and block their PnP irps. Does there any other method so that we can block these devices ( PCMCIA, SCSI and IDE) from a single driver. Your comments and suggestions are welcome. regards John Tag: forceIfDriverIsNotBetter DPInst Tag: 57484

    - Notifications in Printer Driver Hello All, I developed universal mini printer driver which prints a image rather than output to a printer. I used a rendering plug-in and some GPD files. I need to compress the image created. I have some existing library to do this. I need to do some loading and unloading of objects and other stuff at various print states. My question is which component should i implement to get the notification of the following print states: starting a job, ending job, cancelling job, start doct, ending doc, start page, end page. The rendering plug-in implements OEMStartDoc, OEMEndDoc, OEMStartPage, OEMSendPage. Is this the correct component to handle my requirement? I did not find any job related routines in rendering plug-in. Which component should i implement for print job related status like start,end and cancelling a job? Do i need to implement a print processor or print monitor? Is it possible to implement everything in a single component? Any suggestions would help me. Thanks in Advance. Regards, Madhu.

    - graphics function in windows 98SE Hi, Can anyone tell me about the sequence of various graphics functions being called in windows 98 SE to draw the screen over monitor. regards, Andy Tag: forceIfDriverIsNotBetter DPInst Tag: 57476

I'm trying to test unsigned driver (miniport) installation using DPInst.exe.
I tried running it with the /f /q /s command line options expecting it to
install as described in the documentation. It does not seem to work. When I
run it with just /f /q options, it says "it did not install because it was
not better than the software you currently have...".
Why does not this work? I also tried setting these flags in the DPInst.xml.

I can also add that this miniport driver is being installed for a device that
already has a driver (obviously). So this is an "update". A manual update
driver via the Control Panel -> Device Manager works fine.
