    - Can I use safe string functions at raised IRQL? The WDK states that these functions (RtlStringXXX) must only be used at IRQL passive level. I need to perform some string operations at DPC level and all of my strings exist in non paged pool. Is it ok to use these functions at IRQLs > passive level in these cases? I noticed that the implementations of all the safe string functions are in ntstrsafe.h and they are not wrapped in a #pragma PAGED_CODE section so I suspect that this is ok. Are there any dangers of using these functions at raised IRQL that I may not be aware of? Tag: Does User Mode driver requires a certification? Tag: 91622

    - Volume mount fails after Volume{Class-GUID} exceeds 9999 I am unable to create partition/assign drive letter for disk drive. Up on checking the registry "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{71A27CDD-812A-11D0-BEC7-08002BE2092F}" the subkeys number reached maximum limit i.e 9999. ( http://www.microsoft.com/technet/prodtechn...7.mspx?mfr=true ) at the same time, if I delete a subkey from then list, I am able to create/mount the volume. looks like, Windows keeps the subkeys of volumes which is no longer valid ( disks were initially presented to the host and later removed) is this a microsoft limitation? is there any workaround to remove all the invalid references so that operation succeeds Tag: Does User Mode driver requires a certification?

    - MSI install bus driver Hi all, I'm usind WIX and DifxApp to install drivers (MSI packages), until now the drivers installations have been ok. But Is it possible to manage Bus Drivers installation by MSI ? I've no error on generating the package (installation's files are ok) the problem is when i install the bus,i've no error too but the installation seems to be the same as a "simple" driver, the system waits for a "plug device" to finish the installation! => Only a pre-installation is done! Is there anything special for a Bus driver package to do? Or it's simply not possible?! Thanks Rach. Tag: Does User Mode driver requires a certification? Tag: 91608

    - Showing Advanced Tab for recording endpoints in Vista Hi, I'm having some issues to show the advanced tab of my recording endpoints in Vista. I've implemented an audio driver using AVStream architecture for a USB device. For the capture pin, my driver support DataRangeIntersection calls. What I found is that in order for the advanced tab to be shown, I must allow for multiple instances of the recording pin to be created. But I'm only prepared to support 1 instance of recording pin, and the advanced tab does not show up when I support only single pin instance. Can anyone provide some help?

    - Drivers I am having trouble with 3 drivers at this time. I cannot get Bluetooth to work on my hp dv2000t. I reinstalled drivers, and would have fully functioning Bluetooth, and if I restart it hangs and windows will not load. I have to boot to last know good working configuration. Then Bluetooth no longer works and I cannot fix it. I also cannot connect my iPod. It continues to search for drivers and nothing. I cannot find any online, and I have installed iTunes and uninstalled and still nothing. Today I stuck my memory stick pro into my integrated memory card reader, and it searched and searched for drivers. Nothing again. SO I looked for drivers. Found them, installed them, and now all I get is a safely remove hardware icon in the system tray. I cannot get to the actual device to remove the pictures or see what's on it. OR DO ANYTHING... I have been messing with this computer all dang day and I really need some help. Please if you have these issues and have resolved them, help me too!! Also if you have no issues and your plug and play devices work fine. Let me know I want to know if there is something I am missing. Thanks in advance!

    - Toaster Filter driver Hello guys, I have a question. I have modified some of the KMDF toaster sample filter driver from WDK6000 and tried to install this to one of usb function driver to see if I can get the right IRPs from it. But unfortunately I couldn't make it work when I install it with the INF file coming with the sample code. How can I modify this INF file to make it sit on top of one of the USB devices? or is there a simple way to do it manually as use to be with the WDM?? I used to make a registry key "UpperFilters" in the designated device and disable/enable the device manually, then it was working fine. How can I do this with the KMDF? Should I always use the INF to install it? even to the filter driver? Thank you. Tag: Does User Mode driver requires a certification? Tag: 91586

    - When exactly USBD_STATUS_ISO_NOT_ACCESSED_BY_HW is reported ? Hi, To give you a little background of my query, We are developing a USB Host Controller and it is expected to work with the standard HCDs (usbehci / usbohci) on Windows XP SP2. All the devices, except high-speed isochronous (camera), work properly. With the HS camera (logitech) we see that enumeration is all success, but we don't see any picture. Upon debugging further we observed that the client driver of the camera gets all the packets back with the status 'USBD_STATUS_ISO_NOT_ACCESSED_BY_HW' ! The URBs are posted with USBD_START_ISO_TRANSFER_ASAP flag set. On the bus however we see the Isoch transactions going (and device responding to it). As very little information is available on this, I was curious as to when the USBEHCI resorts to this return value. Exactly what causes it to deduce that 'the controller did not access the TD asocated with this packet' ? Any pointers will be greatly appreciated.

    - 1394 Driver Install Prompts When Only Chip ID Differs Hi All, Is there any way to prevent the user from being prompted for .inf and .sys files when a second or more 1394 device is plugged in of the same type? e.g. When only the Chip ID of my device is different? It seems Windows should recognize when it sees a second 1394 device of the same manufacturer and device name (but only the chip id differs) and load the driver for that device. It seems that this can be done since I'm not prompted, for instance, when two different USB memory sticks are plugged in of the same model. Thanks in advance. As always, any help is appreciated.

    - Network adapters immediately re-detected/installed after uninstall Can anyone explain why, when uninstalling a network adapter class device, the OS immediately reinstalls it. Sometimes even while the uninstall is still in progress? Or can anyone confirm that this is actually a bug in Vista? It doesn't appear to happen with any other device class - just network adapters. Uninstalling any other class makes it's instance disappear from Device Manager. With network adapters though, it looks like there is a PnP refresh and it re-detects the hardware.

    - Filesystem overlay (poor mans unionfs) Hi there. For a legacy application that expects all its customization (.dlls, mostly) in its working directory and because I need to constantly switch projects (which involves "copy the working directory, replace it with another one and restart") I searched for a kind of unionfs[1] for windows, which would allow me to create a logical view on the application directory which includes external directories as neccessary. Sample: C:\MyApp\Bin\ C:\MyApp\Projects\Foo\ I'd like to map all file requests that would fail for the Bin to check another directory again. Being new to this stuff (and doing it out of lazyness, since the process described above sucks) I'd love to hear that this barely involves dispatching IRP_MJ_CREATE? My current idea would be to deploy a minifilter which does the following steps in the PreCreate event: - Check if this request wants a file inside of my Bin directory., else ignore the request - Check if the request is readonly (no create file, no append), else ignore the request - Check if the requested file exists (ZwFileOpen?) and - ignore the request if the file exists - redirect the request to the overlay directory otherwise (setting the filenameinfo and marking the request as dirty) Since I'm bloody new here: Can anyone comment on obvious mistakes? Is this too hard for a beginner's (talking about drivers here) task? Thanks in advance, Ben Tag: Does User Mode driver requires a certification? Tag: 91547

    - print driver default settings strategy in 2003 server and xp Hi, in a point and print relationship between printQ on 2003 server and xp client, I set up "advanced / printings default" in the print driver option on the server. When the customer install (with point and print method)the printer on the XP, the default setting in the driver match the printQ configuratin of the server. Everything seems ok I use this method for setting up a global print strategy (like force duplex and black and white printing by default).But when the user changes default printing options locally, system keeps this setting as default. I'm looking for a way to allow the user changes setting "on the fly" when printing, but forbid permanent local settings change. In other words, when user opens its application again for printing, default printings option should match the server one. Thanks in advance for your help.

    - bulkusb sample with DTM test Hello, I am new to DTM test. I use Vista DDK's bulkusb sample to transfer MP3 files between PC and Handset. The Handset just has a bulk-in and a bulk-out pipe, and our purpose is just to transfer MP3 files. It works on Vista. Now I use DTM to test it, the .inf shows it belongs to USB class (just like bulkusb.inf). I use usb cable connect handset and pc. And I choose WDK\ConfigureUSBController in MCU Ploicy tab to start DTM test. And then I create a submission(x86 Vista) to run test items(it shows 7 items on DTM Studio) and always failed immediately after I schedule these jobs. All I want to ask are: If the .inf must has a CAT file first and I must add a CatalogFile=XXXX.cat and can not give it a blank CAT file? If I should make a CAT file first and then can do other test items, or they will all fail? Should it must connect through a usb 2.0 HUB? I had test HCT before, it seems simpler than DTM. I am not sure about DTM whether something important that I must to do and I forget to do. Please help me. Thanks. Ricky Tag: Does User Mode driver requires a certification? Tag: 91533

    - Poor DMA read rate I have a PCI device (32-bit/66MHz) that has a really poor DMA read rate (host to device) that is somewhat decent in one machine (59MB/s) but is really poor in another machine (4MB/s). The performance in the second machine is equivalent to directly reading memory from the host 4-bytes at a time. The DMA write rate (device to host), however, is roughly the same in both machines and close to the theoretical (262MB/s). The device acts as the master for both reads and writes. I have a limited knowledge of the details of the PCI bus. Does this look like an issue with the PCI bridges getting configured differently, resulting in the read transactions being terminated prematurely? I have access to a PCI analyzer and will be setting that up as soon as I have access to the machines again, but I was wondering if this looks like something obvious to someone more knowledgeable about the PCI bus. Also, are there any parameters that can be tweaked to improve the read DMA rate overall? I realize that this is probably highly dependent on the DMA engine on the device itself.

    - Help!! Out of the Pot and into the Driver Fire I need some help. I have been thrown in front of a bus at work. We are having trouble fully testing our network enabled apps for their resilience to the effect of lag and dropped packets and I got tagged as the lucky developer to find a solution. As usual, we can't buy anything; but, in this case I cant find anything that would work anyway. I need to create a small app that will allow me to catch UDP/TCP packets going up and down the stack and hold them for a resizeable amount of time to "fake" lag for our app. I also need to be able to throw out packets based on some known frequency and unknown (psuedo-random). Of course, None of us here are Windows driver developers, but from the research that I've done, it looks like I will need to make a Intermediate NDIS driver and/or Filter driver. I am pretty sure I can't do this project in VS 2005, and I need the WDK....Right? Are there any other things that I will need before I install the WDK? I have been studying the MSDN literature on NDIS intermediate/filter drivers, but I am not real sure where to go next. Thanks a billion for any help.

In CreateClose routine: irp.Status = STATUS_SUCCESS; irp.Information = FILE_OPENED ; IoCompleteRequest(irp, IO_NO_INCREMENT); return STATUS_SUCCESS; Seems to be OK. I'v tried to call IoCreateSymbolicLink. Same promblem. Whats wrong? Tag: Does User Mode driver requires a certification? Tag: 91513

    - Communication with driver Hi, I'm currently developing a user mode application that creates a rather big linked list which contains lots of structures that may contain linked lists theirselves. Now, how can I transfer this rather complex linked list into kernel mode? What's the best approach? Thanks a lot, Peter Tag: Does User Mode driver requires a certification? Tag: 91508

    - HP lagging in providing printer drivers for Vista my HP1012 laser printer does not work in Vista. I have posted asking for help elsewhere ... I am interested in reading opinions on why HP would be so slow in having printer driver support for printers on Vista. - the 1012 is no longer sold by HP but it is still relatively new. assuming HP is providing Vista support for the printers it sells, will it be difficult for HP to clone one of their working drivers to work with the 1012? - in general are printer drivers harder to write in Vista than XP? - has HP simply become a lame company that has little regard for its legacy customers? -Steve Tag: Does User Mode driver requires a certification?

    - How to properly support an interface in an upper filter driver ? I am an upper filter driver and set & Enable an interface (IoRegisterDeviceInterface & IoSetDeviceInterfaceState() . Depending what stack this filter is on , the stacks below it will fail IRP_MJ_CREATE , some will succeed it. Some stacks depend on the IRP_MJ_CREATE , if filter completes with success , they are not happy. If the IRP_MJ_CREATE fails , user mode apps cannot access my interface, and value of filter. What is the proper method for supporting this ? Tag: Does User Mode driver requires a certification? Tag: 91506

    - How do I clean up the registry Hi, When I run ndistest, 1c_faulthandling test modifies the registry to simulate various error conditions (causing scenarios). During one of the test-runs, system crashed in 1c_faulthandling. Now I am unable to load the driver because of some tweaking done by 1c_faulthandling. Question is: How do I restore the registry/fix this problem? Regards, -Praveen Tag: Does User Mode driver requires a certification? Tag: 91501

    - USB Selective suspend support by Vista? Our device is a usb 1.1 low speed device with remote wake up capability. and it runs with the Vista in-box hid driver. it also passed USBCV suspend/remote wake up test, Well, after choosing maximum power saving policy in the Vista, we still can not obeserve the driver would send out the "set feature" command to enable the remote wake up function in our device. The deivce keep working on D0, and was not able to go into a power saving state. ""========= Per the ..http://msdn2.microsoft.com/en-us/library/ms793200.aspx In Microsoft Windows XP and later operating systems, the USB core stack supports a modified version of the "selective suspend" feature that is described in revision 2.0 of the Universal Serial Bus Specification. The USB selective suspend feature allows the hub driver to suspend an individual port without affecting the operation of the other ports on the hub. Selective suspension of USB devices is especially useful in portable computers, since it helps conserve battery power. Many devices, such as finger readers and other kinds of biometric scanners, only require power intermittently. Suspending such devices selectively reduces power consumption. More importantly, as long as any USB device remains powered, it will prevent the system from entering deeper sleep states, such as C3. The Windows selective suspend behavior is different for devices operating in Windows XP and Windows Vista. ""========== Once the device keep working on D0, it would prevent the CPU enter C3, it would result in the whole system consume more power.. Does anyone knows 1. The in-box HID driver in Vista support seletive suspend feature? 2. If yes, what's the requirement for arming the command to the device? Thanks. -chueh8 Tag: Does User Mode driver requires a certification? Tag: 91495

    - Multiple MiniportMessageInterruptDPCs on the same CPU In the following scenario, does NDIS call one MiniportMessageInterruptDPC per MSI message or just one DPC call? 1. The driver uses two MSI-X messages. 2. MiniportMessageInterrupt always sets QueueDefaultInterruptDpc to TRUE and returns TRUE. 3. The device sends one MSI message and interrupts a CPU. This causes a DPC. 4. While the last DPC is either running or is scheduled to run, the device sends a different MSI message and happens to interrupt the same CPU. Is this always going to result in another DPC because the interrupt is due to a different MSI message? Thanks... Tag: Does User Mode driver requires a certification? Tag: 91490

    - 1394 Debugging - So Close - Need Help I've set up my host and target machines for 1394 debugging. I have the virtual 1394 device drivers installed on the host machine and am able to connect to the target machine to begin the debug session. Right after the target's 1394 host controller loads, the debugging connection is lost. When I check the target's hardware properties, the 1394 host controller is whacked. I've read the documentation that warns to disable the target 1394 host controller before debugging with the caution "Be careful not to accidently disable the 1394 net adapter instead". The problem is, when I disable the 1394 host controller on the target, the 1394 net adapter disappears from the listing and thereby not allowing a debug connect at all. Any help would be greatly appreciated. Tag: Does User Mode driver requires a certification? Tag: 91488

    - IOCTL_SCSI_PASS_THRU commands in limited user mode Hi, Currently I am using IOCTL_SCSI_PASS_THRU commands in admin user mode, when logged in limited user mode I am not able to send IOCTL_SCSI_PASS_THRU commands to an USB device. The reason is Create file will fail due to Generic_read/Generic_write which is not available in limited user modes, and IOCTL_SCSI_PASS_THRU needs these options in DeviceIOControl. As I am working with USB Mass Storage device using usbstor.sys mass storage driver is there a method that would send same commands through USB end points or pipes. Also I found IOCTL_USB_USER_REQUEST which has USBUSER_PASS_THRU option but I could not locate any sample codes, i guess these are not documented. What I am trying to do is to send an vendor specfic command to an USB Mass Storage deivce. Thanks, JK Tag: Does User Mode driver requires a certification? Tag: 91485

    - machine hanging after reboot when enabling driver verifier When enabling the driver verifier and rebooting the machine (done automatically for some tests by DTM), the machine is hanging during the reboot. I can reproduce the problem also by doing the same thing manually (without DTM). I have Windbg attached and it seems the system is hanging at the very beginning: it seems the driver under test is not loaded yet, the last messages from windbg are "kernel debugger connection established", some stuff about symbol paths and "system uptime: not available" as last message. I'm only able to break into the debugger until after a very long time (more than 10 minutes). The strange thing is that I do not see the problem on all my test machines. I'm currently using 2 machines: the one which has the problem is a single-processor machine, the other one, which is a multi-processor machine, does not have the problem. Another difference between them is that the one with the problem has both XP and Vista installed on it while the other has only Vista installed. Both are 32-bit machines. Has anybody already seen this problem before or does anybody have suggestions to debug this problem? Thanks, Jeroen Tag: Does User Mode driver requires a certification? Tag: 91476

    - inf update Hi, I made a USB WDM driver. I am trying to make an update on my driver. Every time I use the update driver the system crash. And I can't find anything wrong. I have to physically remove first the old driver and reboot I was wondering if there is anything in INF to specify the removal and/or the replacement and/or reboot of the system. Thanks.

    - Tcpip.sys bug: FTP Upload. MiniportHalt isnt called untill it has returned all the outstanding sends. So, set up an FTP upload, then do a safe remove. Result, underlying USB bus driver gets the query remove and retuend INVALID_DEVICE_STATE for the Ndis miniport driver writes, but the miniport drivers Halt routine doesnt get called and the device doesnt get unloaded, hanging the PnP manager with device manager showing the device stil present. (You can tell the PnP manager is hung because an inserted USB stick isnt recognised). Via an applet and an IOCTL interface, the Ndis driver can be told to stop, whereupon it cancels all its send packets with a status of NDIS_STATUS_MEDIA_DISCONNECT. After this has hapened the miniport halt function does get called. So, from looking at the DDK: The PnP Manager issues an IRP_MN_QUERY_STOP_DEVICE request. On receiving this IRP, NDIS calls the ProtocolPnPEvent function of all protocol drivers that are bound to the adapter. In this call, NDIS specifies an event code of NetEventQueryRemoveDevice. If a protocol driver fails the NetEventQueryRemoveDevice event by returning a failure code from ProtocolPnPEvent, the PnP Manager might ignore the failure and subsequently succeed the IRP_MN_QUERY_STOP_DEVICE request (but it looks like it doesnt) ... After all protocol drivers are unbound from the NIC, NDIS calls the miniport driver's MiniportHalt function. So, it looks like tcpip.sys is failing the NetEventQueryRemoveDevice because it still has outstanding sends with the Nic driver, but the Nic driver cant complete them till its Halt function is called. Chicken...egg...chicken...egg. This is on XP SP2. I wonder if its 'fixed in Vista', like selective suspend ; ) Tag: Does User Mode driver requires a certification? Tag: 91474

I was wondering:

I need to develop a driver for my USB device and I found that Vista now
support a User mode driver.
Does that means that those do not require a certification?

Regards,
DC
