    - Driver Dev for Win Mobile 5 I am having trouble creating the driver installation package for a USB to Serial adapter cable. The chipset manuf. has provided the .000 and .001 as unsupported files only. What I need to do is connect our PPC Phone Ed. devices (T-Mobile MDAs) to our telco switches/routers (VT100 emulator prog.) for diagnostics and basic config for our techs. Since the drivers for WinMob 5 are .dll, which is the best way to create an install package or manual indstall? I am a primarily a 3-Tier entrerprise application and SOA developer and have not had to write a driver for years. Additionall,y I have just been handed our mobile device dev./mang. and am under a tight schedule. Any info would be great. - S-Rez BT Americas NYC Sen.

    - Getting the "bus relations" of a device I have a webcan that is both appearing in the "USB controllers" and "Imaging Devices" sections in the Device Manager. How can I find the relations between the two drivers (in user mode). I have tried SetupDiGetDeviceRegistryProperty but it seems there is no unique property that I can use. One possible way would be to retrieve the "bus relations" of a device as displayed in the Device Manager->Device XXX->Details->Bus relations. But how ?

    - How can I register multiple Coms via a virtual serial port driver? Hi friends, I have written a virtual serial port driver using a pair of bulk endpoint of USB. It can register a virtual COM symbol such as "COM3" in my computer. The driver function well using WIN32 applications. Now I have requirement to emulate 3 COMS at the same time in host computer via this pair of bulk endpoint. Questtions: 1.First I have to find a feasible way to register 3 COM symbol, they are symbolic link to FDO, how can I register them at the same time? 2.Only one PDO(physical device object) is created by lower USB driver , then I have to register 3 FDOS(functional device object) , fatal error occured when I attach them to PDO using IoAttachDeviceToDeviceStack(), How can I deal with it? 3. Is there any sophisticated virtual driver sample for my requirement? Waiting for expert's comments. All your comments are welcome.

    - PCI express payload mystery We have got our WDF driver up and running with an 8 lane PCI express card. It uses hardware DMA scatter gather and appears to be working well. However we are only getting about 50% of the theoretical bandwidth over 8 lanes (1GB/s instead of 2GB/s). Unfortunately we need to hit around 60%. The 50% doesn't include driver overhead and is measured by the hardware during the transfer. One of the main factors that can affect PCI express efficiency is the payload size. From what I have read the maximum payload is 4k which is supposed to give near to 100%. For 128 byte payloads with an estimated application overhead it's around 55%, and for 64 bytes it is around 40%. On our AMD platform as we are not measuring the overhead, it is feasible that we're getting 64 byte payloads (our card supports 4k). A few things we have noticed so far: ATI X1900 XT has a maximum payload size of 128 (according to SiSoft tool) Intel 965 chipset has a maximum payload size of 128 (according to the data sheet). Here are a couple of questions I hope someone can shed some light on: 1) On an AMD system PCI express is interfaced by HyperTransport which is packet based, and has a maximum payload size of 64 bytes. Does this mean its PCI express interface is also limited to 64 byte payloads? 2) Does anyone know of a motherboard chipset that supports large payloads (4k)? Apologies if this is slightly off topic, but I guessed it is something that will affect anyone writing a PCI express driver. Tag: WinMobile 5 Driver Dev For USB to Serial Adapter Tag: 86785

    - SCard reader driver is not getting registered properly hence not I have modified the ddk sample for smart card reader, pscr to support the PCI interface. I installed smart card reader driver i could able see my driver details in the registry (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MySmartreader). But, Smart Card Subsystem is not recognizing my reader, that means he is not adding my registry details to (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\calais\Reader) . I have a GEMPLUS Serial reader hardware and .sys file, which is installing and passing driver details to above registry with my inf file (with their device and vender ID). So, I think my driver initialization is not proper in the driver, I have updated all the mandatory parameter in the SMARTCARD EXTENSION Structure. What else need to be done to make my reader driver visible to the resource manager. Regards Esha Tag: WinMobile 5 Driver Dev For USB to Serial Adapter Tag: 86782

    - AddPrinterDriver failed. Hi friends, I have used DRIVER_INFO_3 with AddPrinterDriver API to install my printer driver manually. In 32 bit OS its working fine. But in 64 Bit versions (windows Xp x64) I am getting an error message saying that "The system cannot find the path specified". (ERROR_PATH_NOT_FOUND =3). But the printer driver path is retrieved through "GetPrinterDriverDirectory" API only. Even I tried with direct addressing also.(c:\windows\system32\x64\spool\drivers\3...).But in both methods Iâ??m getting the same error message. Please suggest me how to come out from this problem.

    - EMF I grant to you I m a bit confused about the workflow during a print job. Where is the best place to catch the EMF Output ? I did it now in the printprocessor trough copying the Spoolfiles. But they may a better place or a more fashionable solution. What's about catching the EMF-Commands in the printdriver or is it better to use a portmonitor ? I want to use it to catch output from vector-graphic programs. Until now I saw the best results if I choose a Plotter as Output device. Has anybody any sugesstions ?

    - virtual disk driver - write a volume header I am writing a virtual disk driver which uses a file as a virtual disk. The disk file can be mounted with a drive letter and normally used. Internally, ZwReadFile and ZwWriteFile in the dispatch routine for IRP_MJ_READ and _WRITE do the job to write on and read from "disk". As far, everything works fine. Now, I would like to write a volume header sector at the beginning of the disk file. This volume header sector should not be formatted by e.g. the windows format command. It should be ignored by any write operation on the disk file. I think I have to modify the StartingOffset in the VERIFY_INFORMATION when IOCTL_DISK_VERIFY comes down and shift as well the offest of IRP_MJ_WRITE to save this special sector for overwriting? Until now, e.g. the windows format begins at StartingOffset 0 and thus, overwrites my volume header sector which was previously written when the disk file was created. Any help would be gratefully appreciated. More info can be provided if applied. Tag: WinMobile 5 Driver Dev For USB to Serial Adapter Tag: 86775

    - MS toaster sample and driver signing When a new toaster device is plugged-in ( using command: enum.exe â??p 1 ) device Setup pops-up a warning that the driver is not properly signed. Question 1. If I use remote desktop the warning message is displayed not on my screen but on the primary or main screen and is not visible to me. I have to login from a monitor which is physically connected to the machine where toaster software runs in order to see this warning dialog and continue the driver installation. Any suggestions how to deal with this problem without passing WHQL tests? The workaround known to me is: go to Device Manager, find the newly created toaster device, select Update Driver and go through the installation process from the very beginning. Question 2. After installing the driver for toaster device number 1 I want to add toaster device number 2. Same warning message pops-up again. I already approved the driver installation for device number 1 and device number 2 will use the same driver. How to avoid the warning if the driver has been previously installed for another device?

    - NDIS Version question. Looking at the sources file for passthru example im driver in the 2003 ddk, it is evident that for a w2k build ndis 4.0 will be used and for xp/2003 ndis 5.1 will be used. I just spent some time researching the different versions of ndis and its seems ndis 4.0 is real old and ndis 5.0 was introduced in w2k. Why then does passthru want to be built using ndis 4.0 for w2k and not ndis 5.0? The sources file looks like this ... !if "$(DDK_TARGET_OS)"=="Win2K" # # The driver is built in the Win2K build environment # C_DEFINES=$(C_DEFINES) -DNDIS40_MINIPORT=1 C_DEFINES=$(C_DEFINES) -DNDIS40=1 !else # # The driver is built in the XP or .NET build environment # So let us build NDIS 5.1 version. # C_DEFINES=$(C_DEFINES) -DNDIS51_MINIPORT=1 C_DEFINES=$(C_DEFINES) -DNDIS51=1 !endif I am tempted to change it to ... !if "$(DDK_TARGET_OS)"=="Win2K" # # The driver is built in the Win2K build environment # C_DEFINES=$(C_DEFINES) -DNDIS50_MINIPORT=1 C_DEFINES=$(C_DEFINES) -DNDIS50=1 !else ...

    - WDF Class Filter Driver Installation Hi, I was wondering if anyone had experience installing a CLASS filter driver on an already existing setup class. I have found limited resources on the subject (at least for a class filter driver), and I haven't found anything on msdn on how to install a class filter driver with WDF. Their link points to here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/devinst_d/hh/DevInst_d/specinst_708d78ad-ba66-40a0-946a-a0bb261e8a8a.xml.asp which directs you to use an app to do the following: 1. Call SetupInstallFilesFromInfSection for the [upperfilter_inst] section. 2. Call SetupInstallServicesFromInfSection for the [upperfilter_inst.Services] section. 3. Call SetupInstallFromInfSection for the [upperfilter_inst] section, once for each class key it wants to register the upperfilt service for. However, I think WDF is a different beast as it requires the wdfcoinstaller to install the runtime. So I am not sure if this method is what I should do (and besides it didn't work). So, I found from osronline that with wdf we are supposed to use WdfPreDeviceInstall and WdfPostDeviceInstall. How do these fit in with a class filter driver? >From what I understand, I can use those functions along with CreateService to install my filter driver's service, but what about registration? As far as I know step 3 in the older documentation says to use SetupInstallFromInfSection to register the class filter driver. Does that only add the "UpperFilters" value to the class key in the registry? Does it do anything else? When I tried to use it I didn't see any entry appear Any help on how to install a class filter driver using the WDF/KMDF would be much appreciated. Thanks!

    - PoStartNextPowerIrp special case I'm curious about something in "Calling PoStartNextPowerIrp" in the DDK docs. In most cases PoStartNextPowerIrp is supposed to be called just before the power IRP is passed back up or completed, except in the case of filter drivers for system power IRPs where PoStartNextPowerIrp is apparently supposed to be called before passing the power IRP down.

    - KMDF Class Filter Drive INITSTARTFAILED Hi, I'm working on a class filter driver but to start I have installed the filter as a device upper filter on a device of the class that I am to filter on (both have services installed at boot time). It works fine as a device upper filter with the exception that in the registry key I have noticed that it sets INITSTARTFAILED to 1 for the enum key of the service (i.e. .../System/CurrentControlSet/Service/myService/Enum). However the count is 1 as is the nextInstance. I thought that if the service truly did fail that the count would be zero? The filter driver installed correctly as it does what it is supposed to do. Furthermore, setting a breakpoint on my driver entry results in the behavior expected (registers my device add and everything). It works as far as I can tell except for the INITSTARTFAILED that is set. I have deleted the key and the next time I boot it is back again. I think this may be a problem because when I try and have the filter be a class filter driver, I get an INACCESSIBLE_BOOT_DEVICE (7b) I just want to make sure this INITSTARTFAILED doesnt' have anything to do with this... In order to make the filter a class filter I have added to the key corresponding to the class guid in currentcontrolset/control/classs with UpperFilters myFilt. I have also tried putting in a CoInstallers32 wdfcoinstaller01005.dll,WdfCoInstaller since when I installed the filter as a device filter it put those values in the device instance key (am I missing something else?) So I guess I really have two questions 1. Anyone know why INITSTARTFAILED would be set to 1, but yet load the service and it function properly? 2. Anyone know if for a CLASS filter driver if there are any other values I have to set besides the UpperFilters in the registry key for the class? Thanks in advance!

    - USB to Ethernet miniport Adapter: SetPower Request handling. Hi, I am writing a USB to ethernet miniport driver. My question is about SetPower Request handling when device is unplugged during Standby. The Device is connected and PC is put to Standby, When the PC is in Standby mode the Device is unplugged. Now the PC is made to come out of Standby. As soon as the PC comes out of Standby we get SET_POWER Request. Since the Device is no longer connected I am returning STATUS_ADAPTER_REMOVED from the SET_POWER request. It seems to work fine in most of PC's but in a few of PC's the MiniportHaltHandler is not getting called. I tried NDIS checked build and we get a message "Assertion failed NDIS_STATUS_SUCCESS == ndisstatus" The other messages that I get are as follows "**** source file: d:\xpsprtm\net\ndis\sys\ndispwr.c, Line 1164 NdisDevicePowerOn: Miniport 82EB9AC8, PowerOn Failed by device driver for the miniport, error C0010018! NdisDevicePowerOn: Miniport 82EB9AC8, PowerOn Failed by bus or device driver for the miniport, with error C0000001!" We get the same status in the PC where MiniportHaltHandler is getting called. According to the DDK documents we should always return STATUS_SUCCESS. But since the Device is no longer connected to the PC, returing STATUS SUCCESS seems to be illogical. If we have to return STATUS_SUCCESS from the SET_POWER request all the time. Is there a specific place (function call) from where we should return STATUS_ADAPTER_REMOVED. I would be very grateful if somebody can throw some light on this. Regards, Anuj Tag: WinMobile 5 Driver Dev For USB to Serial Adapter Tag: 86700

    - Help needed on writing a pseudo audio driver Hi, I have done lots of ground work, but could not find any satisfactory explanation on this. My requirement is like that - i will have an pseudo audio driver registered. For one of my application (voice chat application), I will select this driver for audio i/p and o/p. Application will deliver any incoming voice to the pseudo driver for audio o/p (in normal case, it would have been given to the sound card driver in the system). The pseudo audio driver will forward this voice to somewhere else(lets say X). The pseudo audio driver will get user voice i/p from X and forward it to the voice chat application (in that case X is acting as a microphone source). Initially I was thinking it won't be possible in windows. Then I came across MSVDM where they have written a driver for storing voice to a file instead of o/p it to sound card. I was thinking to tweak this for my purpose, but, as I am new to windows driver I could not understand few things. How about writing a audio filter driver? Please guide me as to what will best suit my requirement. I must admit windows is a very difficult bitch to grab. It is taking hell lot of time. the more I read more I get confused. An early reply will be very much appreciated. Any pointers or help in this regard will be highly appreciated. -paul Tag: WinMobile 5 Driver Dev For USB to Serial Adapter Tag: 86684

When I move cursor, bounding rect of cursor is drawn with wrong image. For example when I move cursor on the desktop, cursor bounding rect of old location will be redrawn with the image which will be there if I dont rotate the screen in my driver. To achive perfect screen rotation do I need to develop any more supporting drivers like miniport filter driver etc? if yes, what should be function of that?

    - PcNewPort the Only Way? I'm trying to develop a dummy audio device for streaming. PcNewMiniport doesnt appear to support any kind of Wave devices. PcNewPort seems affiliated with DMA and pci bus & all that jazz. I know the msavd driver just hacks around it, but is there a more sensible solution? thanks rektide Tag: WinMobile 5 Driver Dev For USB to Serial Adapter Tag: 86661

    - ScsiDebugPrint Okay, I'm pulling my hair out over an issue that does not deserve near the amount of time I've devoted to it. I'm trying to get ScsiDebugPrint to work in a ScsiPort miniport driver. Here's what I've got: - A test "driver" with only DriverEntry. It #includes miniport.h and scsi.h. I have 4 calls to ScsiDebugPrint() in DriverEntry, with 0-3 values for first the DebugPrintLevelArg. - I link against scsiport.lib. I'm using the latest WDK. - I've tried running with a checked build of scsiport.sys that I rammed into the sys drivers dir of my target box (having turned off file protection in the registry [SFCDisable]). - I run with a debug serial hook-up to my target PC. - I've got Debug Print Filter registry entries: DEFAULT, DPFLTR, IHVBUS, IHVDRIVER, IHVNETWORK all set to dword 0xf. - If I change the driver to instead include wdm.h, link against wdm.lib, and use DbgPrint(), this works. But of course I can't use DbgPrint() w/ a ScsiPort miniport driver. Help, anyone?

    - WPA2 pre-authentication I'm working on WLAN driver for Windows Mobile 5. On AKU3.0 I tested PMK cache and it works just fine. But full pre-authentication does not work. When device is connected to the AP it does not try to pre-authenticate with other AP using existing link. It cause full 802.1x authentication when first AP is turned off. Does AKU3.0 support pre-authentication? Is there any additional requerments for the WLAN driver? Thanks, Artiom Tag: WinMobile 5 Driver Dev For USB to Serial Adapter Tag: 86644

    - wdk Vista mirror driver After making the needed changes my mirror driver is back runnning in Vista. But it act the same as before, directx stuff (like screensavers) generate a black screen. In the documentation "3 lines of extra info" they mention GCAPS2_EXCLUDELAYERED GCAPS2_INCLUDEAPIBITMAP but no futher usage doc is available. Tha sample mirror driver have the function DrvRenderhint() this seems to be total undocumented. 1) Does the mirror driver on Vista have a way to capture directx ? 2) Is there any documentation available about the changes between XP and Vista and usage of the new options ?
