    - Is WinXP SP2 support WPA2? WPS ddk says: Authentication modes of WPA2 and WPA2PSK are currently not supported in Windows XP with SP2 and Windows Server 2003 with SP1. So that means Win XP sp2 does not support WPA2 now? If yes, when will Microsoft publish WPA2 supplicant? Regards, RedOctober Tag: Port redirection using Remote desktop Tag: 53323

    - How to access mapped memory from kernel driver Hello, This is probably a very simple thing, but somehow i can not find any examples on the internet dealing with direct memory access. I have embeded board that has battery backed memory - this memory is linked to ram (like video RAM) and it is located at D000:0000 (in DOS like format) I can access this memory from dos and i also can access this memory from winDriver utility and other utilities dealing with memory access from windows XP. however in my kernel driver I'm getting Access violation - code c0000005 (!!! second chance !!!) error on any attempt to acces this memory range. I have portions of my driver accessing ports - this works fine so I'm really lost here. this is what I'm doing: in driver entry: PHYSICAL_ADDRESS MemAddress; ULONG MemLength; MemAddress.HighPart = 0x00000; MemAddress.LowPart = 0x0D0000; //NVRam Base Address (d000:0000, 4 kb window) MemLength=0x1000; //4kb window ...... ResourceList.List[0].PartialResourceList.PartialDescriptors[1].Type = CmResourceTypeMemory; ResourceList.List[0].PartialResourceList.PartialDescriptors[1].Flags = CM_RESOURCE_MEMORY_READ_WRITE; ResourceList.List[0].PartialResourceList.PartialDescriptors[1].ShareDisposit ion = CmResourceShareDriverExclusive; ResourceList.List[0].PartialResourceList.PartialDescriptors[1].u.Memory.Star t = MemAddress; ResourceList.List[0].PartialResourceList.PartialDescriptors[1].u.Memory.Leng th = MemLength; ..... devExt->MemLength =MemLength; HalTranslateBusAddress(Isa,0,MemAddress,&MemType,&MappedAddress); devExt->MemBase = MmMapIoSpace(MappedAddress, MemLength, MmNonCached); ... works with no erros the value of devExt->MemBase is set to something like ( F416F000 or F4526000 and so on - it it helps to understand my problem) in reading IOCTL i'm doing this: *(PUCHAR)pIOBuffer = READ_REGISTER_UCHAR((PUCHAR)((ULONG)devExt->MemBase + 0x00) ); and it giving me Access violation - code c0000005 (!!! second chance !!!) nt!READ_REGISTER_UCHAR+0x4: 80516ef8 8a02 mov al,[edx] Actually the best way for me is to access this memory just by pointer, something like varchar=*((PUCHAR)((ULONG)devExt->MemBase+Some_Seed)); this also do not work , with same error what am I doing wrong? Also, should I setup and use DMA instead?? Thank you Alex Novikov Tag: Port redirection using Remote desktop Tag: 53318

    - PsSetCreateProcessNotifyRoutine What is the problem with unloading a driver that called PsSetCreateProcessNotifyRoutine?

    - SetupCopyOEMInf SetupCopyOEMInf does not recopy the file if it finds that a binary image of the specified INF file already exists in the INF directory with the same name or a name of the form OEM*.INF. My question is: If I wanted to replace the INF file and OEM file every time installing the driver, what method or function call I need to use in order to make this happen? I used CopyFile() to copy the INF file while installing but it pop up the window asking for the DLL file and I don't want the pop up either, it suppose to be silent install. I also tried SetupCopyOEMInf(szInfFullPath2, NULL, SPOST_PATH, SP_COPY_REPLACEONLY, szInfNameAfterCopy, MAX_PATH, NULL, NULL) to replace the INF file and I got error code 0x80070002 Any help are apreciated, Thanks, Hannah.

    - 1394 + WinXP SP2 Hi All! Unfortunately, I'm a total newb to driver development and I have a broken driver that I have no idea whats going wrong. Its a 1394 isocronous camera driver that was developed on W2K but had been working on XP until SP2 was released. Now the driver will no longer load itself. The failure occurs on IOCallDriver which returns 0xC0120090. The error is defined as STATUS_FLOAT_INVALID_OPERATION. I can not determine what that error means. The driver is in the process of initializing an address space to receive quadlet write requests (status messages) from the camera. An isochronous channel and bandwidth has not yet been allocated at this point. Any hints or clues would be greatly appreciated! Regards, John Tag: Port redirection using Remote desktop Tag: 53283

    - Where to find more detailed INF description? Hi I have the problem that I don't get usber.sys working on Windows ME. On Win2k it works, but I guess that it's more luck than knowing what exactly goes on (there are some good examples to find). The key-problem is, that the i.e. registry entries are not fully specified (what's possible in the Install section). Does anybody know where to find a more detailed information about INF files, i.e. what different registry entries are possible, or how to extract a default driver from default Windows installation CD, etc? Without additional information it will stay trial-and-error to complete the INF file - but still: how to know about existing possibilities without having a description about it? Many thanks for help Holi Tag: Port redirection using Remote desktop Tag: 53280

    - How to set up a USB driver to read an Interrupt End Point Dear Experts, I have a device with an interrupt endpoint where data can be asynchronously sent by the device. To read this data, I have followed the technic presented by Mr. Walter Oney in his book on WDM driver - setup a End Point in transaction to be always pending on the desired end point. This technic works functionally but reads data one byte by one. This is slowing down my driver. I want to setup this pending IRP to read as many bytes as are present in the EP buffer in one shot. How do I do this? Do I simply set the IRP to read multiple bytes? What will happen if the device has just one byte to be sent? Will this not keep the IRP pending till the device has as many bytes of data as requested? I do not want this to happen either - I want to read "as many bytes as present at the time of issueing this IRP" without waiting if less no. of bytes are present. Thanks for any ideas.

    - How to precisely control timing write I/O to lpt with driver? can someone tell me how to precisely control timing to write I/O out to Lpt with kernel mode driver? I had compiled and modified a kernel mode parallel port driver, a user mode dll to export I/O read and write, and a MFC application that issues I/O read and write through the driver to an externel device connected to the parallel port. Everything seem like ok, but when i use QueryPerformanceCounter and QueryPerformanceFrequency api in the MFC application to obtain accurate desired timing delay (in nanosecond accuracy), the application writing out a waveform to the Lpt to the external device, may not appear as accurate as desired. Sometime the delay appear longer, though most of the time it works fine. In some computer it has such delay error appear at every particular interval. And it will not produce a desired delay when a CD or music is played at the computer. below is the source code: do{ BOOL bResult = ::QueryPerformanceCounter(&liCurrentCnt); if(liCurrentCnt.QuadPart < liBeginCnt.QuadPart) { AfxMessageBox("Error occured in timing!"); // never happen break; } }while(liCurrentCnt.QuadPart < liMaxBoundCnt.QuadPart); Is there any solution to this problem? Is there any method in kernel mode driver, that I can hog the CPU processing for a certain amount of time? Or is there any way can I put my application thread or driver service routine to the highest priority that no other software can interrupt it? Can anyone please help?

    - Interrupt handler with an event flag We are passing an event flag (from "CreateEvent") into a Device Driver with the command "DeviceIOControl" to signal an Interrupt from the hardware back to the software and make sure it is properly synchronized. This works OK until we try to close the Windows Console application when Windows 98 hangs up and needs to be rebooted. Walter Oney's instructions were heeded: closing the handle to the Device Driver and calling "ObDereferenceObject" with "KeReleaseSpinLock" to release the event flag inside the Device Driver. However the Windows Console application still does not exit cleanly. Any clues would be appreciated. Tag: Port redirection using Remote desktop Tag: 53238

I am using a fairchild transceiver with the opencores usb1_funct and usb_phy which ( according to their forum ) works out of the box. I am also going to post on there incase the problem is at that end. Could someone point me in the right direction 1) Has the device responded? If so, is it a corrupt response (i.e. a noise or timing issue). Has it stalled? According the device it has not stalled or had any CRC or overflow errors. 2) Can it be recovered (by some call into the driver, such as a reset) that will allow me to continue, or is it terminal. If I do nothing and simply try to write to using 'WriteFile' it just locks up. Thankyou, in advance, to anyone that bothers to reply to me! Matt Tag: Port redirection using Remote desktop Tag: 53232

    - How to support 3 packet transfers for USB 2.0 isochronous ? USB high speed isochronous can transfer up to 3 packets in a microframe. In wMaxPacketSize of end point descriptor, bit 0 ~ bit10 indicates maximum packet size and bit 11~ bit12 specify the number of additional transaction opportunities per microframe. The driver usually prepares USBD_ISO_PACKET_DESCRIPTOR->offset by multiplying wMaxPacketSize. Now the driver would issue isochronous read and the device may transfer 3 packets in a microframe. How does driver prepare the ISO packet offset? ISO->offset = i * (wMaxPacketSize & 0x3FF) * 3 Is the above code correct ? XPDDK usb isochronous sample code uses wMaxPacketSize directly though it said high speed transfer is supported in the code. Does it support multiple transactions in one microframe?

    - What's Microsoft policy for USBCAMD? Microsoft provides USBCAMD library driver for USB PC camera. In Win2000 DDK, Microsoft still proivdes sample code for usbcamd.sys. In XP DDK, the sample code is removed since Microsoft don't want vendors to replace Windows build-in usbcamd.sys. So I think Microsoft hope vendors only develop usbcamd mini driver for their usb pc cameras. However, usbcamd.sys doesn't support multiple interfaces device. What driver model does Microsoft recommand for multiple interfaces device? Currently, Microsoft provides usbvideo.sys and recommands vendors follow USB video class spec. USB video class seems to be multiple interfaces device. One interface is for some descriptor tables and the other interface is for video stream. Vendors still need to provide their own driver for old OS. Does any one know the answer? Best Regards Jackal Huang Tag: Port redirection using Remote desktop Tag: 53187

    - OID_PNP_CAPABILITIES Problem Hi, I'm trying to enable wake on wireless in my device driver but am enable to check the boxes in the Power Management Screen(i.e. Properties Window) for my Wireless Lan Driver. I have returned the query to OID_PNP_CAPABILITIES in accordance with the NDIS document and see that there is no change in the check box status as yet. I would appreciate any help in fixing this.

    - NDIS Driver question Hello, I am trying to explore PASSTHRU sample, provided by MS. So far, I am facing two problems: 1) how to hide the corresponding checkbox in network adapter properties dialog box? I know that commercial firewall programs (Kerio firewall for example) do not put any checkboxes there... 2) How to force system initialize driver? DriverEntry is never called. Thanks.

    - WDM streaming driver and user mode interaction I have a WDM streaming driver(Video) solution and I want that to interact with a user mode component( a Service Exe loaded at logon time in my case). What would be the best way to go about this ? Basically, the service sends some data eveyr now and then to the streaming minidriver. Should I use IOCTL's and send data excluseively ? or shall I use FileMapping or some shared objects ? 1>I know there are no direct IOCTL's going into the streaming minidriver as the class driver handles everything. But can I overload the class driver's IRP_MJ_DEVICE_CONTROL with mine ? 2>Should I use Property Sets and Plug ins ? Remember that the service will need to send data every now and then( and I am thinking of using Events to communicate between driver and the service where driver initiates an event and the event when evoked, either does an IOCTL or some other way to communicate data to the streaming minidriver) so the calling would be something like a service -> Plugin -> Minidriver ? 3>any other method that anybody can suggest ? Thanks. Tag: Port redirection using Remote desktop Tag: 53149

    - How to send proprietary commands to a mass storage device ? Hi, I have to access to an USB device declared as mass storage (or maybe CD) in order to send proprietary commands from an application without the need to write a kernel driver. I guess that using CreateFile with a name as \\.\PHYSICALDRIVE<x> or \\.\<x>: will be fine to send a proprietary command to my device via a DeviceIoControl. But after some investigations, I did not find any way to do this. I expected mass storage commands to be available from user mode. Can anyone give me some hints about this ? Thanks and regards, Jean Tag: Port redirection using Remote desktop Tag: 53143

    - How to find the size of data in SystemBuffer? Hi, I am writing a serial upper filter driver which needs to be able to monitor the read and write data for a serial port. The driver is on a port being used by Windows "Dial Up Networking" to establish an Internet connection via a modem. The buffering method used by RasDial is METHOD_BUFFERED (Mdl is NULL). I can see the write data in my DispatchWrite routine OK and the size of the data in SystemBuffer is correctly reported in OutputBufferLength I use a CompletionRoutine to see the read data coming back up but although the contents of SystemBuffer appear to be correct the size is wrong. It is reporting the same size that was passed down in IRP_MY_READ request and not the actual size of the data received. How can I find the actual size of the data present in SystemBuffer? Thanks O.C.

    - GetCommState Function I wrote some functions to open, close, read and write to our custom printers. In the open function, I use GetCommState to get the serial port state. It compiles with no problem. When I use the function, I get the error Invalid Function when GetCommState is called. The weird part is that first it works fine, but when I uninstall the printer and I reinstall it, that's when I get the Invalid function error. Here is part of my code: hFile = CreateFile(thePortName, GENERIC_READ|GENERIC_WRITE, 0, 0, OPEN_EXISTING, (DWORD)NULL, 0); if ( hFile != INVALID_HANDLE_VALUE ) GetCommState(hFile, &dcb); -- Vern Tag: Port redirection using Remote desktop Tag: 53131

    - DDKBuild ISSUE with WINDDK... Hi Mark/All, My Dev Env is: Windows2000 + VC++ 6.0 + Latest DDKBuild + WINDDK (windows server 2003 ddk) Env variable is set to: W2KBASE C:\WINDDK when I create the project as it's been suggested by MARK at his website www.hollistech.com I get a directory called "objchk_wnet_x86" under my source directory which contains all the .sys, .pdb and others.... (this is right after creating the project and build it for the first time) then I make the change to let say one or multiple of .c files and do the build again.... build goes through with no error.... then I look at my .sys file under the "objchk_wnet_x86" and I'll see that it hasn't been updated... the creation time is still the old one.!!!!!! why? then I delete the log file and all the old file and do the build again and guess what... It doesn't generate any of the outputs??!!! what is happening here is what i have under the project setting Build command line: ddkbuild -debug -W2k checked . Rebuild all options: /a Output file name: passthru.sys Browse info file name: passthru.bsc the system works (regenerates and updates the outputs) if I unistall the WINDDK and install NTDDK (Windows 2000 DDK) with the following setup My Dev Env is: Windows2000 + VC++ 6.0 + Latest DDKBuild + NTDDK (windows 2000 ddk) Env variable is set to: W2KBASE C:\NTDDK Build command line: ddkbuild -debug -W2k checked . Rebuild all options: /a Output file name: passthru.sys Browse info file name: passthru.bsc Do I need to make any change in source/make file? do I have to set certain option under the IDE??

(WDF support coming soon.) What exactly do you mean by not working? Also try running "ddkbuild -h" as that will pop up the man page for the script. You do have to set an environment variable correctly along with the correct command line options to indicate which ddk you are using and where it is located.

Hi,

When "Serial Port" redirection is enabled for TS sessions over the WAN,
writting to PORT using WriteFile is slow. But same works fine over LAN.

Is there any settings needs to be done to improve the performance ?

Client (placed remotely) is using remote desktop to connect to windows
server 2003. Pole display device is attached to his local WS.
We use CreateFile & WriteFile WINAPIs for Pole Display. These works but only
issue is, it is slow when accessing it over the WAN.

Thanks in advanced,

WAN is always slower then LAN :)
