    - Wakeup problem with PCMCIA card I am writing a WDM driver for a simple PCMCIA card and testing it under Windows 2000/SP3. The driver is based on a framework created with Walter Oney's WDM Driver Wizard. In particular, the Power handling functions are more or less unchanged. My problem is, that when the system wakes up from standby mode, Windows thinks that the hardware has changed and starts the New-Hardware-Wizard. The driver appears to complete the processing of the power IRPs, but then receives a IRP_MN_SURPRISE_REMOVAL request, following which the driver is unloaded. The New-Hardware-Wizard indicates that it has detected a device named MTD-0002. I have been advised that this probably means that Wihdows is unable to read the Card Information Structure (CIS) on the PCMCIA card, but I can see no reason why this would be the case. I have set D3Latency parameter to 1000 (100ms) which should be more than enough. On inserting the card into the slot, Windows never has any difficulty reading the CIS, so I don't see why there should be a problem when it is powered up on leaving standby mode. Does anybody have any idea what could be causing this effect? I would be grateful for any help. Thanks in advance Phil (By the way, this is newly developed hardware and the error could be in the CIS. It is not a big problem for us to reprogam this memory.) Tag: WHERE TO FIND THE DDK? PRINTERS DDK? Tag: 27775

    - how to display bitmap on screen constantly? Hi, I'm trying to find a way to display a bitmap on the top- right portion of the screen at all times, even when an application using directx in full-screen mode is in use. Can this be accomplished using display filter drivers? I was thinking of writing a driver that would simply map the bitmap data to the screen along with the rest of the screen data. So, could a filter driver be installed "below" GDI and Directx that would map the bitmap regarless of wich interface(gdi or directx) is in use? And if so, since GDI and directx are different components that each communicates directly with the video adapter (as I understand it), will the driver have to be device specific? Anyway, if u guys know a way to accomplish this bitmap mapping whitout using drivers i'll be more than happy to hear it. Tag: WHERE TO FIND THE DDK? PRINTERS DDK? Tag: 27768

    - Enable/Diable Device Driver from Non-Admin account In our Video Conferencing systems, we have multiple propritary drivers running on the system and also our system works with different third party Conferencing Devices. Obviously differnt drivers for variety of HW devices are running on the same system. Our recent version of HW is getting problems with one of HW that is colloborated with our unit. Then I played with different drivers and finally I found a way to make it work. Disable the HW unit driver before reboot and enable after the system booted completely using Windows ddk api from one of test app. But the Microsoft documentation is expalaining that these APIs for Enable/Disable, SetupDiChangeState, is only for Administrator group. Is there any way to disable / Enable the Drivers when we login as a Non-Admin also. Can somebody to help to solve this problem. If I am following the wrong way, Can you update me the proper way to solve this issue. Thank You Murthy Tag: WHERE TO FIND THE DDK? PRINTERS DDK? Tag: 27743

    - sub-optimal performance through CardBus controllers on Windows Problem Statement - The Windows XP and 2000 driver in the OS for CardBus controllers are not programmed for optimal throughput or performance. Observations - We have a Network adapter that runs roughly the same speeds as a Fast Ethernet NIC. - We can sustain data rates in the Tx and Rx directions (simultaneously) of roughly 80Mbps through the NIC and Ndis driver across PCI. - When running through a Cardbus controller programmed by Windows (with the Windows provided Cardbus controller drivers) we see Rx rates of approximately 78 Mbps. Tx rates top out at roughly 38 Mbps. - We have noticed that the Cardbus bridge is NOT programmed for optimal performance, even though the PCI configuration space shows settings that the CardBus controller driver seems to be ignoring. For example, burst read and write were set in the PCI config space for the card (MBURSTDN and MBURSTUP) but the CardBus controller is NOT programmed to burst by the Windows OS CardBus controller driver. - When we manually change the cardbus controller to enable bursting, the Tx performance improves dramatically. Questions. 1. Can the Network card do anything to influence the Windows Cardbus controller driver to enable Burst read and write ? 2. Are there other settings the Network card can use to ensure the Cardbus controller is set for optimal performance? 3. The Fast Ethernet NICs must have run into this same problem already. We see that that off the shelf Fast Ethernet NICs also are not running anywhere near optimal performance / throughput. We see simliar rates for Tx and Rx on with Fast Ethernet Cardbus NICs. We can program the CardBus controller maually to dramtically improve the performance but we still do not see what we would expect (90+ Mbps in both directions). Below are some detailed notes about our investigation and characterization of the problem. We are doing performance characterization on our Cardbus NIC, which has a PHY throughput roughly equivalent to a Fast Ethernet NIC (approximately 100 Mbps simultaneously for Tx and Rx). But, we are seeing some performance issues, while transferring data across the Cardbus interface. We have not been able to get the Cardbus interface, on any laptop to transmit data at rates higher than 37 Mbps and receive data across the Cardbus interface at rates higher than 78 Mbps. Also, there are some laptops where the upstream througput is as low as 3 Mbps and the downstream throughput only 7 Mbps. The throughput seems to vary with the part no. of the Cardbus Controller, being used in the laptop. Following is a list of observations that we made while running the tests, with each laptop: 1. Sony Vaio Laptop running Win2k with RICOH 5c475 II Cardbus controller: This laptop showed a throughput of 37 Mbps upstream and 78 Mbps downstream, when we transfered data at roughly 100 Mbps at the PHY layer. 2. Dell Latitude laptop running WinXP with the TI PCI-1420 Cardbus controller: This laptop showed a throughput of 37 Mbps both upstream and downstream, when we transfered data at roughly 100 Mbps at the PHY layer. 3. IBM Thinkpad running WinXP with the TI PCI-1510 Cardbus controller: This laptop showed a throughput of just 3 Mbps upstream and 7 Mbps downstream, when we transfered data at roughly 100 Mbps at the PHY layer. When we monitored the Cardbus transactions on a logic analyzer, we saw that although the controller was allowing DMA bursts, it was issueing a lot of retries, to the device. 4. If we replace the NIC with an out of the box Fast Ethernet NIC, we see strikingly similar numbers in all cases. All the above setups are running the standard Cardbus controller drivers which came with the Operating System and we are running standardout of the box NDIS Miniport drivers, to drive our NIC. So, the question is, how can we get the Cardbus controller drivers on each platform and OS, to configure the controller correctly, to allow maximum throughput across the Cardbus interface ? Programming the TI Cardbus controller manually Since, the datasheets for the RICOH controllers, are not available online, we looked at the Cardbus configuration registers, of only the TI controllers. Following was the default configuration on both the TI controllers on the WinXP laptops: 1. The MBURSTDN and MBURSTUP bits (bits 15 and 14) were set in the System Control Register (PCI Config space offset 80h), for bursts, both for Read and Write transactions. 2. The POSTEN bit (bit 10) in the Bridge Control Register was set, enabling write posting, which is recommended for good performance while bursting. 3. The Latency Timer settings are different on the controllers: TI Controller Latency Timer Cardbus Latency (Secondary Bus Latency) PCI-1420 20 20 PCI-1510 40 B0 4. The KEEPCLK bit (bit 1) in the System Control Register was cleared, which implies that usage of the CLKRUN protocol was enabled, although we implement the CCLKRUN# pin as a NO-CONNECT on our device, since it was decided not to support this protocol. I tried running the tests, after toggling this bit, so that the Cardbus clock is always kept active and is not throttled using the CLKRUN# protocol, but that did not improve the performance, in any way. 5. The PCIRETRY and CBRETRY bits (bits 7 and 6), in the Retry Status Register, are set, indicating that PCI and Cardbus retry timeout is enabled. Following was the configuration of our device: MIN_GNT = 18 MAX_LAT = FF Latency Timer = F8 While running WinXP, we got a similar low throughput of 19 Mbps. Subsequently, looking at the Cardbus Controller registers and we found that again the MRBURSTUP bit was not set by the XP CB controller driver. So, after setting this bit, manually, I was able to acheive an upstream throughput of 51 Mbps. This strongly suggests that the Microsoft WinXP Cardbus controller drivers are not optimized setting the Controller hardware for optimum performance basedon the parameters of the CardBus cards plugged into the bridge. We are wondering if other NIC vendors would have run into the same issues on Windows and got some fixes from Microsoft. Following, we were able to achieve a new performance high on our Cardbus NIC using the Dell Latitude laptop with the TI PCI-1420 Cardbus controller. We were able to acheive 46 Mbps upstream and 79 Mbps downstream, while trying to transmit packets at roughly 100 Mbps. So, we are almost at par with the Cardbus Fast Ethernet performance, seen on the various laptops. The differences this time are: 1. This NIC is programmed with a new EEPROM image which programs the PCI MIN_GNT, MAX_LAT and the latency timer to values optimized for the maximum throughput. 2. Before we started this test, we made sure that the PCI latency timer values on all the intermediate PCI-PCI bridges and PCI-Cardbus controller, was set to the max possible value of 0xF8 (since I found that the latency timer values on some of the intermediate bridges was set to zero, by default, which might have inhibited the Cardbus performance). --- Larry Cawley Airgo Networks, Inc. 636 458 1462 <mailto:LarryCawley@AirgoNetworks.com> Tag: WHERE TO FIND THE DDK?

My current driver is as good as empty, I can successfully start & stop it during a normal (non safe) session. Also it boots up in a normal (non safe) session when being installed as SERVICE_SYSTEM_START. Everything looks just fine. But during safe boot XP suddenly is not able to load the driver. It tries to load it (I've added it to the safe boot registry keys), but it fails. The XP event log sais, XP was not able to load my driver, but it doesn't tell me why. If I check out the properties page of my driver (via device manager) after a safe boot I can see that it is not running. If I then try to manually start it, the dialog freezes for about 5 seconds, but the driver still does not run. What do I have to change to make my driver run successfully in a safe boot? Thanks!

    - WinDDK Fails to Build Examples I've installed the winddk 3790, read the release notes and getting started guide, and attempted to build the examples but I've had no luck-- the build is silently failing. Executing 'build -cZ' from the command prompt spawned by "Windows 2000 Checked Build Environment" rapidly scrolls through all the example directories (much too fast to be building) and exits without errors. If I look into an example (i.e. src\general\portio) at the build log file, I see entries like the following: > Compiling c:\winddk\3790\src\general\portio\sys directory ************* > 'nmake.exe /c BUILDMSG=Stop. -i NTTEST= UMTEST= NOLINK=1 NOPASS0=1 386=1' > Bad command or file name Any ideas? The log output is identical for every example driver in the DDK. I'd expect building examples to "just work" but I'm not familiar enough with this environment to even begin to guess what is wrong. It should be mentioned that I had this exact error mode using a previous Win2K DDK, so I elected to grab the latest 2003 Server DDK in the hopes that the integrated compiler, etc, would make the effort easier.

But if I try to DeviceIoControl() IOCTL_STORAGE_GET_DEVICE_NUMBER, IOCTL_SCSI_GET_INQUIRY_DATA, and other disk and storage control codes as well, after opening the device through CreateFile() with the following symbolic link name, it fails with the error code 50, which means ERROR_NOT_SUPPORTED. \??\USB#Vid_0c76&Pid_0005#0304281630200#{a5dcbf10-6530-11d2-901f-00c04fb951ed} To be more precise, my USB storage device supports Bulk-Only Transport protocol and announces itself as a SCSI transparent subclass device. If there is anybody who had ever stuck in this type of problem, please give me some clues for solving it. **** I have one more question. I'm in the position to develop hardware and software. So for now, I'm trying to compose a small program controlling a mass storage device of another manufacturer. If I'm to develop the firmware without relying on the USB controller customized to the specific application, do I have to write a firmware parsing all the SCSI command set? Or is there any documentation that specifies which part of the standard SCSI command set USB mass storage device spec supports? I'm afraid if I have to deal with a whole bunch of SCSI command set. Need some advice. Thanks Tag: WHERE TO FIND THE DDK? PRINTERS DDK? Tag: 27664

    - Problems sending named events to Driver Hi NG My driver has problems recieving a event from my user mode applikation. But there is no problems recieving the same event in my appilication from the device driver. Thia is what I do: In my DriverEntry i create the event with this: // Create event for user-mode processes to monitor RtlInitUnicodeString(&uszNotifyEventString, L"\\BaseNamedObjects\\AppEvent"); // Trying to create the event NotifyEvent = IoCreateNotificationEvent(&uszNotifyEventString, &NotifyHandle); if(NotifyEvent) { // Success KdPrint(("NotifyEvent event created with success\r\n")); // Clear it... KeClearEvent(NotifyEvent); } I get the handle to the event in my application like this: // Creating event. ITs created by the driver.. hEvent = OpenEvent(SYNCHRONIZE, FALSE, _T("AppEvent")); if(NULL == hEvent ) { return 0; } They both succed. My application then waits for the event: // The events used.. hEvents[0] = pService->HEndThread; byNumOfEvents++; hEvents[1] = hEvent ; byNumOfEvents++; dwWait = WaitForMultipleObjects(byNumOfEvents, hEvents, FALSE, INFINITE); if((WAIT_OBJECT_0 + 1) == dwWait) { // Set event again. Driver does not respond to this SetEvent(hEvent ); <----- No responds in my driver on this } When my driver signals the event ( KeSetEvent(NotifyEvent, 0, TRUE) ) my application is responding OK to the event But when my application sets the event my driver does not respond to it. // Setting event KeSetEvent(NotifyEvent, 0, TRUE); <--- My application responds to this KeResetEvent(NotifyEvent); // Waiting for the service to answer status = KeWaitForSingleObject(NotifyEvent, UserRequest, KernelMode, FALSE, &WaitTimeOut); // Never reached. if(STATUS_SUCCESS == status) { KdPrint(("Got event.\r\n")); // Service has answered. Clear the event. Shutdown in progress KeResetEvent(NotifyEvent); } Any Idea ?? Schould I call the OpenEvent() with EVENT_ALL_ACCESS instead of SYNCHRONIZE ?? If I do I got an error that say "Access is denied". How can I create the event with privilege to do this ?? Thomas Tag: WHERE TO FIND THE DDK? PRINTERS DDK? Tag: 27659

    - Error STATUS_NO_LOGON_SERVERS on HalAssignSlotResources We've developed device driver for PCI device, which worked fine on Windows 2000 and Windows XP. BUT after we installed the latest SP4 for the Windows 2000, the call to the HalAssignSlotResources returns error 0xC000005E , which is translated as STATUS_NO_LOGON_SERVERS. What may be the reason of such behavior? Tag: WHERE TO FIND THE DDK? PRINTERS DDK? Tag: 27644

    - WAVERR_BADFORMAT Error I've got an app plays wav files in MULA format (7) using the standard API calls (waveOutOpen, waveOutPrepareHeader, waveOutWrite, etc.). This app has been running without problem on hundreds of machines and every operating system Microsoft has put out from Windows 95 to Windows XP. Suddenly we've got a client using NT 4 SP6 who's getting WAVERR_BADFORMAT errors returned from waveOutOpen. When I call waveOutGetDevCaps on the device, it puts 4095 in the WAVEOUTCAPS.dwFormat field. Anybody have any ideas what might cause this? Tag: WHERE TO FIND THE DDK? PRINTERS DDK? Tag: 27524

I need a copy of the DDK, particularly for printers. It provides stuff
like code for localspl.dll. MS does not provide this on the web-site.
Anyone know where I could find this? Even better, any chance I could
get it emailed? My driver development for the printer is pretty
advanced (have written a port monitor), but I cannot progress without
the DDK.

You could have found the answer by searching this or related groups.

Microsoft will send the DDK on CD (in the US and Canada at least) for
the cost of shipping, about US$15. I believe the only legal download
site is the Microsoft MSDN, whose membership fee is rather more than
$15.

Ask your friends who has MSDN Pro or universal subscription.
The DDK is included in MSDN delivery on CD/DVD and also available in
subscribers downloads.
