    - doc about EAP Hi, I have created a client that can associate a wireless adapter to a WPA-PSK-tkip network. Now I have been setting up the wired network to use a radius server too (IAS) and I monitored what the wzc send and noticed it starts sending EAP messages instead of EAPOL (in the pairwise handshake and group handshake) Now the 802.11i draft describes more the EAPOL messages, where can I read how the EAP messages are structured and used, at the moment I have set it up to use PEAP-MS-CHAP v2, but also EAP-TLS is interesting. thanks /Niklas Tag: Get the USB host controller speed within miniport driver Tag: 46106

    - Virtual Device Driver Basics Good Day I was wondering where to get information on Virtual devices on windows 2K/XP I want to make a driver that detects if any of our products are connected (Serial/USB) and then acts as a generic PCSC driver to any of these devices. Our clients do not want to layer the driver atop the HID/Serial driver because they also want direct access to the hardware from user mode.. Can anybody help me with this With Best Regards StreaX Tag: Get the USB host controller speed within miniport driver Tag: 46103

    - To Microsoft Guys Hi all I was installing a Proxy server which uses an IM driver on windows 2003 server. It was an old version. (It woks pretty good on 2000) The system generated error message telling that the driver would not be loaded because it can make the system unstable ………but it allowed the bindings to be changed. This caused all the Network communication to stop. Even when I uninstalled the proxy program the bindings and the registry data for the drivers were still there.( I changed the registry entry in driver to make the miniport’s manually un-installable). My question is if Windows determines that the drivers will make the system unstable and will not load them, then why during installation it allows the bindings to be changed …….or why doesn’t it reverts back to the old bindings?

    - How to turn off dithering in (RDP) display driver When an application uses more colors that the video device can generate, the device driver (and/or GDI subsystem ?) for line objects (like text) approximates requested color to the nearest color device can generate or for solid brushes - simulates requested color by dithering (mixing colors in a pattern). In common situations the color simulation is a very useful but sometimes it gives unexpected effects when color of written text is the same as (or similar to) one of dithered colors of the background plane. The lowest color depth of the video device the worse visual effects we get - e.g. for 256 colors video driver for Win 2K Terminal server (based on RDP 5.0 protocol). In such case it could be very interesting to observe how display quality would improve (if any) when dithering will be turned off. But how to disable this function of RDP display driver? Is that any dedicated registry key which controls dithering? Or perhaps is any other way to disable dithering? Thanks in advance A.

    - USB Port resets after S3 standby Hi, I have an application that automatically brings my computer out of standby and immediately issues a command to my USB-based (1.1) infrared blaster. The problem is that it seems Windows XP likes to "reset" the USB ports as it comes out of standby, which takes about 5-10 seconds. I know this, because I can hear the generic USB plug-in sound. And while the reset is happening, the command to the infrared device takes place and fails (because Windows doesn't think the device is present until the "reset" is complete). By the way, the USB device stays on all through the S3 standby (enabled with the correct motherboard jumper settings). So, this "reset" seems somewhat useless to me. Does anyone know how to stop Windows from re-registering the USB port after S3 standby? I'm sorry that this is more of a configuration question than a development one, but I'm not having any success elsewhere.

    - Driver Chain Manager Hi, all! Did anybody write driver, compatible with DCM? Task is to write magnifier. I think, this will require tapping video driver. DCM establishes a set of rules, governing display driver interception. First of all, I should estimate complexity and volume of work. Now, I am trying to write test chain driver, intercepting DDI calls. Questions: 1) I can't compile driver, using WinDDK. Linker can't resolve DCM calls. I have dcmkrnl.dll, dcmuser.dll installed. I do not have any .lib files.(Do I need them or I can manege with .dll files?) What should me adjust? 2) Documention, that I have found, is insufficient. I don't have samples, that I can modify. Does anybody have samples or detailed documentation? 3) DCM is a relatively new component. Is it reliable enough? Yuri Tag: Get the USB host controller speed within miniport driver Tag: 46051

    - Generic Device Identifier I am attempting to create a program that will inspect our companies machines and determine any drivers needed for devices based on the hardwareID, DeviceID, etc. One problem that I have encountered is a case where the mouse hardware ID is a generic ID. For example, the hardware ID on a Dell laptop is listed with the generic identifier of: ACPI\PNP0F13,*PNP0F13 This could match any number of mouse drivers, i.e. Alps touchpad driver or Synaptic, etc. The correct driver, or at least the driver shipped with the unit is an Alps touchpad driver. Do cases where a generic hardware ID is listed (and I'm sure there must be others --USB drivers come to mind) mean that any driver/INF matching that ID --whether it is Alps or Synaptic-- will work properly? Secondly, is there a way to determine which is the proper manufacturer/driver to install? Many thanks! JW Tag: Get the USB host controller speed within miniport driver Tag: 46030

    - Strange Shutdown Problem I'm writing a driver for a PCI-Express device, although the "-Express" part should be irrelevant for this discussion. I started the driver from Walter Oney's driver wizard, and the power management code is essentially unchanged from the wizard code. Windows XP SP1a Checked. (I haven't tried Free; I suppose I should...) I can load, unload, and restart the driver to my heart's content. On a system restart, power state goes to D3, driver unloads, everything is happy. But when I try to do a system shutdown, most of the time it gets everything shut down, my power state goes to D3, my driver (apparently) unloads, the kernel debugger disconnects and waits for a reconnect, the screen goes to blue, and that's it. The power doesn't go off. SOMETIMES a shutdown works fine, but most of the time, I get this hang. If our device is not plugged in, it shuts down OK. Anybody have any wild ideas for me to try? I don't THINK it is a driver issue; I don't think the debugger would disconnect if my driver were still running. Any "I saw this once and here's what I did" stories welcome. -- - Tim Roberts, timr@probo.com Providenza & Boekelheide, Inc Tag: Get the USB host controller speed within miniport driver Tag: 46028

    - Wheel tab on mouse control panel Does anyone know how the mouse control panel decides whether to show the "Wheel" tab? Our experiments seem to be indicating that, rather than using some kind of IOCTL_MOUSE_QUERY_ATTRIBUTES call, it may be looking at the PNP ID of the currently installed mouse (at least for PS/2). The symptom is that if we install our driver using a compatible ID (PNP0F13) the tab shows up, but if we install the exact same driver on a device/platform specific PNP (e.g. SYN0010) the tab goes away, with no other changes. If this guess is correct, is there some kind of registry key or something that would cause the Wheel tab to come back? Some of our customers are complaining about it going away. -- ../ray\..

    - USBCAMD2 Video Freeze issue. Hi all, I'm having a stange problem with a USBCAMD2 based driver for a custom USB camera we're working on. We have only 1 video stream whose format is RGB24. In ProcessRawVideoFrameEx(), if I do the following: frameBuffer = (BYTE*)FrameBuffer; frameBuffer[0] = frameBuffer[1] = frameBuffer[2] = 0; . . fill in the rest of the frame buffer with actual data . the video frame is not drawn. However, if frameBuffer[0], frameBuffer[1], or frameBuffer[2] is non-zero, the video frame is drawn (Note that only one needs to be non-zero, not all three). We noticed this because the video stream would "freeze" whenever the first pixel was completely black RGB(0,0,0). As soon as the pixel goes to anything but black, the video resumes. Has anyone else seen this? I find it quite bizarre & can't figure out why it's doing it. Thanks, Jerry Tag: Get the USB host controller speed within miniport driver Tag: 45920

    - User-mode midi-driver Hi everyone, I'm not sure if this is the right place to ask for, but I will just go ahead: I'm currently writing a virtual midi-driver which is implemented in a user-mode-driver mymidi.drv. I have taken the sample from the nt 4.0 ddk and adapted it to my needs. I got two problems: 1.) If I install on a system where no midi-driver has been installed previously, my driver will not show up in the audio & midi settings in the control-panel. I think that I need to install some MS component which will not exist until the first midi-driver is installed... Any hints, on what I need to include in my inf-file? 2.) If I get this thing installed right (on a system which already got a midi-port active), the driver is installed. Unfortunately there, the audio & midi settings control panel applet won't start any more. With OutputDebugString I found out, that my driver is loaded and the DriverProc is called with "DRV_LOAD" - but that's it... Does anyone have ideas why driver-loading seems to fail (even so bad that the control panel applets aborts)? Best regards, Tobias Tag: Get the USB host controller speed within miniport driver Tag: 45905

Get the USB_BUS_INTERFACE_USBDI_V1 interface from the bus and call
IsDeviceHighSpeed. For an example on how to send query-interface, take a
look at the ToasterGetStandardInterface function in the
toaster\func\toaster.c file.
