DOCUMENT:Q174504 09-AUG-2001 [winnt] TITLE :Detection of IntelliPoint Mouse on Serial Adapter Fails PRODUCT :Microsoft Windows NT PROD/VER:WinNT:4.0 OPER/SYS: KEYWORDS:kbsetup ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation version 4.0 - Microsoft Windows NT Server version 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== Windows NT does not detect the IntelliPoint (wheel) mouse if using a serial adapter. It will detect a serial mouse or a PS/2 mouse, but, if the PS/2-style IntelliPoint mouse has a serial adapter, Windows NT does not detect it. If a serial mouse driver was previously installed, Windows NT will use it; however, the Mouse tool in Control Panel shows the mouse type as Unknown and the Change button is grayed out. CAUSE ===== Windows NT Plug and Play service is not handling the migration of the mouse and keyboard devices at each boot properly. Windows NT installs the device as class Unknown instead of class Mouse. And, after the device type is set to Unknown, Windows NT stops trying to detect it. RESOLUTION ========== To resolve this problem, obtain the hotfix below, or wait for the next service pack. STATUS ====== Microsoft has confirmed this to be a problem in Windows NT version 4.0. A supported fix is now available, but has not been fully regression tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix. Contact Microsoft Technical Support for more information. ====================================================================== Keywords : kbsetup Technology : kbWinNTsearch kbWinNTWsearch kbWinNTW400 kbWinNTW400search kbWinNT400search kbWinNTSsearch kbWinNTS400search kbWinNTS400 Version : WinNT:4.0 Issue type : kbbug Solution Type : kbfix ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
