 - IOCTL_STORAGE_RESET_DEVICE = error "incorrect function" The device is type CDROM, is not on a scsi bus and not a scsi device. This complies with the ioctl usage per MS. I code in pascal but the C version of devio I'm using would be I think ... DeviceIoControl(handle, IOCTL_STORAGE_RESET_DEVICE, NULL, 0, NULL, 0, &returned, NULL); ... devio returns an "incorrect function" error. The parameters are per MS as far as I can tell. I can substitute IOCTL_STORAGE_EJECT_MEDIA and it works fine. Thanks for any ideas, Bill Mudd Tag: Safe to remove hardware icon Tag: 70867

 - snetcfg crashing...please help I'm trying to revive about 4 year old VPN Client written as a shim and a virtual adaptor. Installation program does something like this: 1) snetcfg.exe -l .\shimmer.inf -c s -i no_shimmer followed by 2) install.exe netvpntp.inf *no_vpntp Those two programs were checked-into code base and compiled as part of the build. I don't know if they were customized or not. Now, when I try to run those commands from command line, snetcfg.exe crashes and install.exe fails. Here are the respective stack trace and failure msgs. snetcfg.exe crash: msvcrt!wcscpy+0x8 netcfgx!HrCiInstallFilterDevice+0x192 netcfgx!CFilterDevices::InstallFilterDevicesIfNeeded+0x184 netcfgx!CModifyContext::ApplyChanges+0x5cb netcfgx!CModifyContext::HrApplyIfOkOrCancel+0x24 netcfgx!CImplINetCfg::Apply+0x2f snetcfg!HrInstallNetComponent+0x12f snetcfg!wmain+0x14d snetcfg!wmainCRTStartup+0x12b KERNEL32!BaseProcessStart+0x3d install.exe output: .\install.exe netvpntp.inf *no_vpntp Search for Device ID: [*no_vpntp] Compare device ID: [ACPI\ACPI0003] Compare device ID: [*ACPI0003] Compare device ID: [ACPI\PNP0000] Compare device ID: [*PNP0000] ....... .......

 - USB drivers oddity on Win2K This is strange, and I'm wondering if it's something I've done. We have a USB composite device that has two endpoints, one of which is used as a debug channel and one which is a mass storage interface. The mass storage interface works just fine.. however.. When our system (Windows 2000) crashes, it sometimes forgets that it needs the "USB Composite Device" driver and we have to manually reinstall it! This is somewhat tedious and painful, as you might expect, since it looks like that driver has to be reinstalled for each port that we're putting one of these devices on (ugh). I've looked over our debug interface driver code and I can't find anything that would cause Win2K to decide it doesn't need the composite interface any longer. Has anyone seen anything like this before? Does WinXP handle composite devices better? Are there any known issues with composite USB devices under Win2K? All help appreciated, I'm running out of hair to pull out! Tag: Safe to remove hardware icon Tag: 70857

 - UNIDRV Banding Line Count error? Hello, I've got a rendering plugin with ImageProcessing doing RGB24 to CMYK custom halftoning. (That is, DevNumPlanes = 4, DevBPP = 1, DrvBPP= 24.) The conversion itself works fine, *except*: when UNIDRV is doing banding, if the last band is shorter than the previous bands, the difference (in lines) is added to the print as garbage raster data. E.G: for a 3300 line Letter page: ImageProcessing reports 4 x bands of 664 lines, then one of 644. What is printed is the 3300 lines expected, plus (664 - 644 =)20 lines of garbage. For a 3750 line page: ImageProcessing reports 4 x bands of 752 lines, then one of 742. The expected 3750 lines print, plus 10 lines (752 - 742) of garbage. It *looks* like when Unidrv splits the page into bands, it's not tracking the actual count when passing the bands to Output. Comments? Suggestions?? I'd rather not do the compression and output to spooler myself, if there's a known fix for this issue. Thanks! -- Joe C. -- J.C. Tag: Safe to remove hardware icon Tag: 70856

 - Unload what SetupDiCallClassInstaller loaded After disabling/enabling a device with a call to SetupDiCallClassInstaller, my program's memory usage jumps from 900Kb to 9.5 MB (WinXP, according to TaskManager and ProcessXP). Msdn explains: SetupDiCallClassInstaller calls the class installer and any co-installers that are registered for a device or a device setup class. This function loads the installers if they are not yet loaded. The function also calls the default handler for the DIF request, if there is a default handler and if the installers return a status indicating that the default handler should be called. How do I UNLOAD the class installer and co-installers, that are eating my memory? Tag: Safe to remove hardware icon Tag: 70851

 - Miniport's IOCTL interface performance issue. Hi all, I have written a NDIS 5.0 virtual miniport driver that send and receive packets from a usermode application via Direct IOCTL interface. All seems to be working well, except that the miniport drops packets if it receives more that about 3000/second. I have implemented a receive buffer in the miniport and it is clear that the miniport receive all the packets from the above protocols and queue them accordingly but the IOCTL interface seems to be to slow to handle all of the packets, so the queue overflows. Is there any way to improve the IOCTL interface's performance? Thanks, Amos Tag: Safe to remove hardware icon Tag: 70836

 - Driver design thoughts Yes, I'm a driver newbie... We have an open source kernel driver that needs accurate and high-resolution timestamps in order to stamp communication packets. Then, we have an external reference clock producing these timestamps. The problem is to forward these timestamps to the driver. My plan is to write a new driver that interfaces the clock (with serial based protocol) and exports a method for the existing driver in order to request timestamps when needed. This way the existing driver would stay as intact as possible. Does this sound reasonable to you? As far as I understand, my new driver would not be a real "device driver" representing any device, but a kernel-mode helper library. So, what type of driver it should be? Any other thoughts of architectural design? Thanks Ali Tag: Safe to remove hardware icon Tag: 70832

 - scsi rescan caching Hi, Regarding the Microsoft own rescan.exe, as found at: http://support.microsoft.com/default.aspx?scid=kb;en-us;308669 I have found this very utility and particulary the CM_Reenumerate_DevNode() call, which is used within to do actual bus rescan, are behaving as if there is some caching involved. Test as follows: 1. run rescan over and over, from command line, as fast as you can (or write a shell script to do it) 2. Observe how long does it take, each time, for rescan to finish You will see the very 1st rescan does take some time to finish while all subsequent are returning IMMEDIATELLY. Then again, after 30 or some iterations, rescan AGAIN takes some time, as if it actually doing something. I made no device additions in that time. Machine was idle. Test is reproducible. Note I did above test with both NORMAL and CM_REENUMERATE_SYNCHRONOUS setting for CM_Reenumerate_DevNode(), same behaviour. Any thoughts on this?

 - "build" not showing all build - fixed Several months ago, I noted that the DDK "build" utility would in some cases NOT show all errors encountered during a build. I have today found out that this is a side effect of installing the Windows DDK to a path containing spaces. Moving the DDK to a space with no spaces, allows all errors to appear as expected. If anyone is interesting in troubleshooting the DDK build utility, here's a quick way to reproduce it: 1) install DDK to C:\Program Files\Windows DDK 2) drop the 3 files listed below into C:\temp\ 3) Launch a build environment DOS window (in my case Windows 2000 checked) 4) in directory c:\temp, type "build -cZ" ==> The only error shown is an *.obj file missing. The *.log file, however, lists lots and lots of errors. Here are the files I used to reproduce the issue: makefile ========= !INCLUDE $(NTMAKEENV)\makefile.def sources ========= TARGETNAME=temp TARGETPATH=obj TARGETTYPE=DRIVER C_DEFINES=-DNDIS_MINIPORT_DRIVER SOURCES=temp.c temp.c ========= #include <ntddk.h> #include <ndis.h> NTSTATUS DriverEntry( IN PDRIVER_OBJECT DriverObject, IN PUNICODE_STRING RegistryPath ) { return STATUS_SUCCESS; } Good luck! Maybe one of these days the DDK will allow people to use spaces in their paths & filenames.... :-) / Hannes. Tag: Safe to remove hardware icon Tag: 70804

 - uDAPL on Windows? I need to write a driver for a set of PCI-Express boards and there has been a request for supporting uDAPL as the API for interacting with this hardware. The implementations of uDAPL on windows that I have seen appear to be in their infancy and there is a surprising lack of information out there describing what a driver needs to provide for services in order to support this API. Can anyone point me to either some really good documentation or tell me another API that is more "at home" on Windows that would accompliush the same thing (an RDMA type of aAPI). All the uDAPL stuff I have seen has been geared toward Linux support with windows being an afterthought. Thanks, Beverly Tag: Safe to remove hardware icon Tag: 70799

 - USB stack gives misleading indications when Polling Interval not 1 I am seeing some incorrect indications from the usb stack (XP SP2) when my device indicates a Polling Interval of 2 on its isochronous endpoint: My hardware has a high speed (not high bandwidth) iso In endpoint; it generates fixed size 1000-byte packets at an interval very slightly over 250uS. I have taken the isousb sample from the 3790 DDK, and adapted it to work with my configuration. Because of the data rate, it seemed sensible to increase the polling interval on that endpoint so as to only poll every other microframe, so I set a value of two. I use the test app (rwiso) to read an amount of data from the device, and the driver output is as follows: IsoPacket[0].Length = 0x03E8 IsoPacket[0].Status = 0 IsoPacket[1].Length = 0x0000 IsoPacket[1].Status = 0 IsoPacket[2].Length = 0x03E8 IsoPacket[2].Status = 0 IsoPacket[3].Length = 0x0000 IsoPacket[3].Status = 0 IsoPacket[4].Length = 0x03E8 IsoPacket[4].Status = 0 IsoPacket[5].Length = 0x0000 IsoPacket[5].Status = 0 IsoPacket[6].Length = 0x03E8 IsoPacket[6].Status = 0 IsoPacket[7].Length = 0x0000 IsoPacket[7].Status = 0 IsoPacket[8].Length = 0x03E8 IsoPacket[8].Status = 0 IsoPacket[9].Length = 0x0000 IsoPacket[9].Status = 0 IsoPacket[10].Length = 0x03E8 IsoPacket[10].Status = 0 IsoPacket[11].Length = 0x0000 IsoPacket[11].Status = 0 IsoPacket[12].Length = 0x03E8 IsoPacket[12].Status = 0 IsoPacket[13].Length = 0x0000 IsoPacket[13].Status = 0 IsoPacket[14].Length = 0x03E8 IsoPacket[14].Status = 0 IsoPacket[15].Length = 0x0000 IsoPacket[15].Status = 0 IsoPacket[16].Length = 0x03E8 IsoPacket[16].Status = 0 IsoPacket[17].Length = 0x0000 IsoPacket[17].Status = 0 IsoPacket[18].Length = 0x03E8 IsoPacket[18].Status = 0 IsoPacket[19].Length = 0x0000 IsoPacket[19].Status = 0 IsoPacket[20].Length = 0x03E8 IsoPacket[20].Status = 0 IsoPacket[21].Length = 0x0000 IsoPacket[21].Status = 0 IsoPacket[22].Length = 0x03E8 IsoPacket[22].Status = 0 IsoPacket[23].Length = 0x0000 IsoPacket[23].Status = 0 So this suggests that every other packet is coming back zero-length. However, when I look at the entire buffer from the user-space app there are no gaps - every piece of data *is* there (and correct) from beginning to end - all 24 packets. The return value from the read() call is 12*1000 yet the whole buffer has in fact been written. I've also used SnoopyPro to examine what the stack thinks the packets contain, and diagrammatically (and very much simplified), this is what I'm seeing (with "." indicating a zero-length packet): According to stack Actually in buffer 0 1 2 3 0 1 2 3 . 4 5 6 7 8 9 A B 8 9 A B . C D E F 0 1 2 3 0 1 2 3 etc This is a problem to me because I will occasionally get genuine zero-length packets (due to the data generation being asynchronous to the usb frames), and I need to be able to detect them. The USBD_SHORT_TRANSFER_OK flag is not set. This only happens when the Polling Interval is 2; when it is set to 1 then the behaviour is as expected (albeit interspersed with genuine zero-length packets, generated by the h/w when it is polled but has no data available) I'm running a free build XP SP2, but with checked versions of ntoskrnl, hal, usbport.sys, usbccgp.sys and usbd.sys (also from an SP2 version). Is it a bug in the usb stack? There is a report of this kind of problem - http://support.microsoft.com/?kbid=837371 - but although it is dated only a few days ago, it seems to be saying that the issue is fixed in SP2; and I have newer versions of all the files indicated (though why don't I have usbccgp.sys - isn't that needed for composite devices??) [I'm having trouble with my Win2K installation at the moment, so I've not had a chance to compare]. In fact, as I repeat the test today to check my results (before hitting "Send"), I'm *also* now seeing an additional effect: a packet with a length of 1000, but contents all zero - but, again, without any loss of data - where there *is* data in the buffer it is continous and valid (the data stream contains a count to help spot discontinuities). What with the results I was seeing yesterday plus this additional weirdness I'm now seeing, I'm wondering if there are still issues with non-one values of polling interval? Anyone got any thoughts? Can anyone at MS confirm whether 837371 really is fixed? Thanks. Tag: Safe to remove hardware icon Tag: 70727

 - Windows Xp and interrupts. I'm writing a driver for programming performance counters in PIV processor. I've wrote bus driver which enumerates devices and allocates resources and function driver which will do main job. I'm having a problem with allocating resources for functional driver. Currently my IRP_MN_QUERY_RESOURCES handling function looks like this: static NTSTATUS HandleQueryResources(PDEVICE_OBJECT pdo, PIRP Irp) { NTSTATUS status = Irp->IoStatus.Status; PIO_STACK_LOCATION stack = IoGetCurrentIrpStackLocation(Irp); KdPrint((DRIVERNAME " (PDO) - HandleQueryRequirements\n")); PCM_RESOURCE_LIST resourceList; PCM_FULL_RESOURCE_DESCRIPTOR frd; PCM_PARTIAL_RESOURCE_DESCRIPTOR prd; ULONG resourceListSize; // // Following code shows how to provide // boot I/O port resource to a device. // resourceListSize = sizeof(CM_RESOURCE_LIST); resourceList = (PCM_RESOURCE_LIST)ExAllocatePoolWithTag (PagedPool, resourceListSize, APICBUS_POOL_TAG); if (resourceList == NULL ) { KdPrint((DRIVERNAME " (PDO) - HandleQueryRequirements: STATUS_INSUFFICIENT_RESOURCES\n")); return STATUS_INSUFFICIENT_RESOURCES; } RtlZeroMemory( resourceList, resourceListSize ); resourceList->Count = 1; frd = &resourceList->List[0]; frd->PartialResourceList.Count = 1; // // Get pointer to first Partial Resource // Descriptor in this FRD. // prd = &frd->PartialResourceList.PartialDescriptors[0]; prd->Type = CmResourceTypeInterrupt; prd->ShareDisposition = CmResourceShareShared; prd->Flags = CM_RESOURCE_INTERRUPT_LEVEL_SENSITIVE; prd->u.Interrupt.Level = 3; prd->u.Interrupt.Vector = 64; prd->u.Interrupt.Affinity = -1; Irp->IoStatus.Information = (ULONG_PTR)resourceList; KdPrint((DRIVERNAME " (PDO) - HandleQueryRequirements: STATUS_SUCCESS\n")); return STATUS_SUCCESS; } But IRP_MN_START device in my function driver doesn't get any resources(either translated or raw). Can anybody explain me haw handle this IRP correctly? And please anybody explain to newbie meaning of Interrupt.Level, Interrupt.Vector fields? How should I implement IRP_MN_QUERY_RESOURCE_REQUIREMENTS handling function? Best Darek Tag: Safe to remove hardware icon Tag: 70724

 - Converting Win2k monolithic printer driver to a Longhorn driver - Installation problems Converting Win2k monolithic printer driver to Longhorn driver - INSTALLATION Problems.. The current monolithic(not using Microsoft Universal Printer Driver Model) Windows printer driver has been converted to "user-mode" and installs/runs fine on Win2k, WinXP, and WinServer2003. However, for "Longhorn Beta1" the following error message is given during an attempt to install the driver: Error Message: "The driver that you are trying to install is not compatible with Windows Server 2003 family. Please contact the manufacturer for an updated version." It appears (according to the following windows log files: setupapi.app.log, setupapi.dev.log) that the installation (via the Add Printer Wizard) successfully copies the driver files to a system location, but immediately after that point, the error occurs and the installation is cancelled. I suspect that when the "loader" attempts to load a driver DLL (toward end of installation), it cannot resolve a reference in the DLL to some Win API function (NOT IN Longhorn), and therefore the DLL is not loaded. Normally, one would get some kind of error message that indicates a particular function could not be found/resolved; but this may not be the case while using the "Add Printer Wizard". I placed calls to "MessageBox(-)" at several "entry-point" functions in the DLLs (like DllMain, DLLInitialize, WinMain, DrvQueryDriverInfo, etc.) but these are NOT reached during installation on "Longhorn"; however, they are reached during installation on the other OS's. Any Ideas? Rudy Tag: Safe to remove hardware icon Tag: 70716

 - USB Problem when using a Philips ISP1521 based hub We are using a TI TUSB3410 USB to Serial chip and recently identified an issue when using this device with a Philips based ISP1521 based Hub. On the USB-IF Developers Discussion Forum a post was made that matches our problem exactly. This post also has a statement that Philips apparently made which states the issue is that the Windows USB host controller driver. Basically Philips states that the host controller driver is not terminating Start Split transactions with a Complete Split transaction. For the original posting see http://www.usb.org/phpbb/viewtopic.php?t=6636&highlight=tusb3410&sid=92ad332153ccee7ed3babd646910e98d. We have been told by TI that Microsoft acknowledges that this is a bug and that it will be fixed in Vista. However in the meantime our customers are experiencing problems when using our hardware with ISP1521 based hubs. My question is, how can we work around this issue? Is there something we can do in our application or in the driver to cause the host controller driver to terminate the split transaction? Thanks in advance for any help in resolving this issue. - Steve - Tag: Safe to remove hardware icon Tag: 70696

 - port monitor UI Hello, I have been trying to find an answer in the newsgroups and MSDN Library for this without success. How does one go about installing a port monitor UI? It's difficult to tell from the library docs whether this can be done either programmtically or through an INF file. Is it at all different from installing a port monitor server DLL? -- Matt Kane m k b a t d i r t y d o t o r g Tag: Safe to remove hardware icon Tag: 70695

 - Installation Issues sample IsoUsb from the DDK As I described before, I want to develop a USB Driver based on the sample on the DDK. I have compiled a driver from that in the 2k3 Server Environment without any error messages and adapted the INF file for the fitting PID&VID of the device. Now I want to check the general communication via the RWISO.exe tool, belonging to that sources.

 - Several problems building the DDK USB-Drivers Examples under W2k BE Hello folks, I beg you to forgive my very little skills in developing drivers. So I'll report my problems right from the start and how I tried to solve 'em. I'm about to develop a USB-driver that implements Bulk-, Interrupt-, Isochronous Transfers. Getting things started, I intended to build the isochronous USB-Drivers from the latest DDKs (3790 & 3790.1830) and communicate with the self-developed device. I'm working on a x86, W2K plattform and because of upward-compatibility on a x86 XP. On both platforms I got the warning, that the existing sample would not be valid for the current OS target. I changed the makefile in looking after a platform >= 0x500, i.e. Win 2k. But problems went on. While the Windows Server 2003 BE builded the driver reliably, the Win2k BE brings up an error C1083: Cannot open include file 'usbbusif.h'. BUILD: Compile errors: not linking c:\usb\sys directory. I looked after the .h file and it appears in %WINDDK%\3790\inc\ddk\wdm\wnet and ...\wxp but not in the adequate w2k-dir. I copied the missing file(s) in ...\w2k but in the aftermath over 700, mostly syntactic errors occured while compiling. The syntax is correct. This sounds clear to me 'cos WNET-Build works fine. I restored the original dirs of the inc\ddk\wdm... I followed some tips in the newsgroup. Although I have no spaces in between dir- or file-names the error still occurs. I have no errors in compiling the test-programs to the usb-drivers of the ddk. I've consulted the DDK-docs, the newsgroups and Walter Oney's 'Programming the WDM 2nd ed.', but none could take me on the fast lane. Now YOU are my only help and I appreciate that very much.

Hi, My question is :
How to get rid of the icon in system tray?

I writed a driver for our usb device, and every when the device
was attached to the PC, the icon would appear in system tray.

How to hide the icon? Should I add something in my driver or in
the inf file?

Advance thanks!
