Hi all. I rebooted XP today and it made it back to the logon screen. Problem is the mouse and keyboard do not respond. The keyboard works as far as selecting "safe mode" etc. but as soon as it get to the ASCii load bar I am unable to press "num-loc" or "caps-lock" it makes it to the login screen But I cannot do anything. I have tried a USB mouse and PS/2 and a usb keyboard and Ps/2 type keyboard with the same problems. any help would be great. Mike.

Ok something new. When I reboot and it goes through the chkdsk, the keyboard works. I can hit esc to get out of it, but when it exits that check it's dead agian.. This actualy started happening right after I uninstalled my logitech mouse drivers, and from what I have found on the net it seems that the uninstall may have disables the keyboard/mouse services in XP? does anyone know if that is possible, and if it is is there a way to fix it from the XP recovery console?

No Mouse/Keyboard hat might help it is not exactly your problem , but very related, you unistalled the drivers and restarted right? SYMPTOMS After you install Windows on a computer that has a Microsoft Natural Keyboard Pro keyboard attached (Device Manager identifies it as a "Standard 101/102-Key or Microsoft Natural PS/2 Keyboard"), some of the Internet, multimedia, e-mail, and programmed hotkeys across the top of the keyboard do not work. If you start the Keyboard tool in Control Panel, click the Hardware tab, click Properties, click the Driver tab, click Update Driver, click Show all hardware for this device class, and then click the Microsoft Natural Keyboard Pro driver, you receive the following warning: Installing this device driver is not recommended because Windows cannot verify that it is compatible with your hardware. If the driver is not compatible, your hardware will not function correctly and your computer might become unstable or stop working completely. Do you want to continue installing this driver ? If you click Yes, the drivers are loaded. After the required reboot, the keyboard and mouse no longer work. CAUSE The "Microsoft Natural Keyboard Pro" updated driver description is misleading. This driver is intended to be used solely with the Universal Serial Bus (USB) version of the Microsoft Natural Keyboard Pro keyboard. Even though your Microsoft Natural Keyboard Pro keyboard has both a PS/2 and a USB connector, the keyboard itself is i8042-port-based, while the USB connector is strictly for the built-in USB hub. Installing the incorrect driver disables the i8042prt port and enables Human Input Device (HID) support, which does not work with this keyboard. RESOLUTION To re-enable the keyboard, use any of the following methods. First, try the Last Known Good Configuration option by pressing F8 at the boot menu. If the Automatic Logon feature is enabled on this computer and has already logged on a user and there is no keyboard or mouse functionality, use one of the following procedures: Use Recovery Console Boot the computer from the Windows installation media and press F10 when you see the "Welcome to Setup" screen to start Recovery Console. Type "cd \system32\drivers" (without the quotes) and press ENTER. Type "ren kbdhid.sys kbdhid.org" (without the quotes) and press ENTER. Type "copy i8042prt.sys kbdhid.sys" (without the quotes) and press ENTER. Quit Recovery Console by typing exit. This causes a reboot. Log on as an administrator and reinstall the regular "Standard 101/102-Key or Microsoft Natural PS/2 Keyboard" drivers by starting the Keyboard tool in Control Panel, clicking the Hardware tab, clicking Properties, clicking the Driver tab, and then starting the Update Driver Wizard. NOTE: You will not have mouse functionality until you reload the correct keyboard driver and restart the computer. Install the full Microsoft IntelliType Pro version 1.1 update or later drivers for Windows 2000 that support the Microsoft Natural Keyboard Pro. These new drivers are available on the Microsoft Web site, and once installed activate the hotkeys across the top of the keyboard.

I got you the right way to , try this this should work, let me know No Keyboard or Mouse After Installing Logitech 9.0 Mouseware Drivers on Windows 2000 This article was previously published under Q256233 IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base: 256986 Description of the Microsoft Windows Registry SYMPTOMS After you upgrade a Microsoft Windows NT 4.0-based computer to Windows 2000, the mouse and keyboard may become non-functional if you reinstall the Logitech 9.0 mouse drivers and reboot the computer. This usually occurs only if the Logitech 9.0 Mouseware drivers were installed on Windows NT 4.0 before the upgrade to Windows 2000. NOTE: Booting the system into Safe mode or using the "Last known good configuration" option does not restore the mouse or keyboard functionality. CAUSE The Logitech installer adds filter drivers to enhance mouse and keyboard functionality. The problem because the installer program adds "Lkbdflt2" and "Lmouflt2" entries to the following registry locations: HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}: UpperFilters:REG_MULTI_SZ: Lkbdflt2 kbdclass HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E96F-E325-11CE-BFC1-08002BE10318}: UpperFilters:REG_MULTI_SZ: Lmouflt2 mouclass These entries require associated entries in the HKLM\System\services key to be added to work properly, but these entries are missing. RESOLUTION WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. To remove the "Lkbdflt2 and Lmouflt2" filter driver entries, use one of the following methods. Method 1: Connected to a Network If the computer is connected to a network, you can remotely edit the registry as follows. NOTE: If the computer is networked but not part of a domain, you may need to map a connection to the computer's IPC$ share by using that computer's local administrator credentials before you can attach with Regedt32.exe as described below. To map a connection to the computer's IPC$ share, use the following command: net use \\remote_computer_name\IPC$ /user:administrator * From another Microsoft Windows NT-based or Windows 2000-based computer on the same network, run Regedt32.exe. On the Registry menu, click Select Computer, and then type the computer name of the computer that has no keyboard or mouse. After you connect, click Hkey_Local_Machine on Remote_Computer_Name on the Window menu, and then navigate to the following key: SYSTEM\CurrentControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318} Double-click the UpperFilters:REG_MULTI_SZ: Lkbdflt2 kbdclass value, and then remove only the Lkbdflt2 entry. Navigate to the following registry location: SYSTEM\CurrentControlSet\Control\Class\{4D36E96F-E325-11CE-BFC1-08002BE10318} Double-click the UpperFilters:REG_MULTI_SZ: Lmouflt2 mouclass value, and then remove only the Lmouflt2 entry. On the Registry menu, click Close. On the Registry menu, click Exit. Restart the computer with the mouse/keyboard problems. After the computer restarts, the mouse and keyboard should be functional. Method 2: Not Connected to a Network If the computer is a stand-alone computer with no networking installed: Boot the computer from the Windows 2000 CD-ROM or Setup disks, and then start Recovery Console. Change to the %SystemRoot%\System32\Config folder, and then rename the System file to System.bad. Change to the %SystemRoot%\Repair folder, then copy the System file to the %SystemRoot%\System32\Config folder. Quit Recovery Console (type exit). The computer restarts. This should return the keyboard and mouse to a functional state. Note however, that any new devices or services that have been installed since the initial installation will be missing. To restore these services or devices to functionality, continue with these steps. Log on to the computer, and then start Registry Editor (Regedt32.exe). On the Registry menu, click Load Hive, navigate to the %SystemRoot%\System32\Config folder, and then double-click the System.bad file. When you are prompted for a key name, type Test. Double-click the Test key to expand it, and then click the Select key. Note the value for the Default value: Default:REG_DWORD:0x1 (This number represents a ControlSetXXX number.) Navigate to the following registry key based on the ControlSet number you noted: TEST\ControlSetXXX\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318} Double-click the UpperFilters:REG_MULTI_SZ: Lkbdflt2 kbdclass value, and then remove only the Lkbdflt2 entry. Navigate to the following registry location: TEST\ControlSetXXX\Control\Class\{4D36E96F-E325-11CE-BFC1-08002BE10318} Double-click the UpperFilters:REG_MULTI_SZ: Lmouflt2 mouclass value, and then remove only the Lmouflt2 entry. Double-click the Test key to collapse the entry, and then click Unload Hive on the Registry menu. Quit Registry Editor. Reboot the computer by using the Windows 2000 CD-ROM or Setup disks again, and then start Recovery Console. Change to the %SystemRoot%\System32\Config folder, and then rename the System file to System.good. Rename the System.bad file to System (with no extension). Quit Recovery Console (type exit). The computer restarts. This should return the keyboard and mouse to a functional state. Note that all previous services and devices are present and operational again.
