    - 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? Thank you for your efforts! -- h.wulff [dont send me an email] Tag: Enabling a device Tag: 57643

    - 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. If my question is too vague and shows my ignorance, maybe someone can direct me to some good educational material? Tag: Enabling a device Tag: 57597

    - 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. Tag: Enabling a device Tag: 57584

    - 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: Enabling a device 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: Enabling a device Tag: 57486

    - USB Host Driver Greetings, We are currently developing a specialized USB host controller mini-port driver that is not UHCI, OHCI, or EHCI compliant for Windows 2K, 2003 server, and Windows XP. The current DDK does not provide any information concerning the interface between the Windows host controller driver (e.g., usbport.sys under WinXP) and the minicontroller drivers (e.g., usbuhci.sys). The design of our hardware requires that we interface to the USB host controller stack at the USB mini-port level, so we need information about how to create a USB mini-port driver for these different operating systems. We've had discussions with other developers who have done this and they've told us we need to contact Microsoft directly to obtain this information. Could anyone please advise us how we go about obtaining this information? Thanks, Keith Tag: Enabling a device Tag: 57443

    - How do USBCAMD for USB2.0 receive over then 1 packet per SOF Hello there, I modify the USBCAMD from video minidrv for using usb 2.0 device. I use bcdUSB to check the device is running on usb1.1 or usb2.0. I also modify the USBCAMD_StartDevice(), so that usb 2.0 device can allocatebandwidth if (bcdUSB==0x200){ USBCAMD_NUM_ISO_PACKETS_PER_REQUEST=256; //32 USBCAMD_MAX_REQUEST=4; //2 } However, when I choice a 900*3 alternating setting, the packet receive 1 packet/1 SOF all the time. I am sure the packet that waiting for transfer is over then 900, but why there is only packet transmitted? I need your help: Where is the point that the USB driver knows there exist more then 1 packet/SOF can be used? Where is the command that the driver set the packet to be 3? Can anybody help? Thank you!! -- D.D. Tag: Enabling a device Tag: 57439

    - how to signal an app from video miniport driver? Hi I have a video miniport driver and i want to signal my application when somethign interesting happens inside that driver. What i want to do is sort of what in pure WDM land would be said to be as : "open the driver in asynchronous mode , and send an ioctl from app to the driver and inside the driver do not call IoCompleteRequest UNTIL sometihng interesting happens . In the aplication , keep waiting on the event associated with the particular asynchronous call." Now the problem following a similar approach in case of vidoe miniport driver is that videoport.sys manages a strictly synchronously serialized interface with all video miniport drivers where at the most ONE VRP can be outstanding at any given time with a video miniport driver. How can i manage to solve this problem ? Should i manage it through EVENT objects shared between user and kernel mode , and by passing the address of the user mode EVENT object to my driver in the call to EngDeviceIoControl ? what would be the best approach here thanks in advance regards Taha Tag: Enabling a device Tag: 57436

    - suggestion needed on win98 display driver Hello developers, I am working on a display driver for windows 98. it is supposed to support the rotation of screen of monitor. I mean to various angles like 90,180,270. While reading ddk documentation i came across various structures like pdevice and gdiinfo. I guess there must be some specific value needed to setup which does this. any hints ?? regards, Andrews Tag: Enabling a device Tag: 57430

    - What's the PScript5 driver's MAX resolution(DPI)? Hello. I'm working in PScript driver in Windows platform. I wanna know what's the PScript driver's MAX resolution(DPI)? I have ever set it to PPD up to 1200 DPI. What's the limit of DPI in PScript driver? Is it different between Win9x and, Win2000 or later? Then, what's the limit of each OS? Thanks in advance.

    - usbccgp.sys Hi, I read somewhere usbccgp.sys is the prefered parent driver than usbhub.sys for a multifunction device. I use usbhub.sys for our usb device on windows 2000 and now want to move it to windows XP. I modified the inf for windows 2000, by simply changed all reference to usbhub to usbccgp. I then use this inf file for the device installation on a Windows XP (we also used tested our driver with the old usbhub with this XP machine), and delete some related .inf file in windows\inf directory and the registry key in HKLM\SYSTEM\CurrentControlSet\Enum\USB\ location. However after inserting the device and suplied the new .inf file. Hardware Update Wizard in XP reports that there was a problem installing this hardware, the name is already in use as either a service name or a service display name. I suspect this is because of the previous installation of this device with usbhub.sys (the XP used with uncleaned registry entry). Is my analysis correct? You guys have any comments? Best Regards, Wayut Tag: Enabling a device Tag: 57423

Hi:

I'm having a problem programmatically enabling my "Local Area
Conection". I've got the NTDDK and have compiled the "Enable" demo. If
I disable the device using the demo, then re-enable it using the demo,
everything seems to work.

But if I use Network Connections, right-click on my "Local Area
Conection" and click "disable", then use the demo to re-enable the NIC,
the "Local Area Conection" does NOT become re-enabled.

What am I doing wrong???

Please use the Devcon sample from the latest DDK. The enable sample from the
Win2K DDK is known to have some problems.

Enabling/Disabling a network connection is the same as PnP enable/disable
of the NIC's devnode.
The way to go is SetupDiCallClassInstaller with proper function codes,
DEVCON (as Eliyas mentioned) is a sample.
