A Bluetooth keyboard or mouse does not work when you start Windows XP Service Pack 2 or Windows XP Tablet PC Edition 2005

After you connect a Bluetooth adapter to your computer for a Bluetooth-enabled keyboard and for a Bluetooth-enabled mouse, the keyboard and the mouse are not detected in Windows when you start the computer. Therefore, you cannot use the keyboard or the mouse in Windows.

This issue occurs if your Bluetooth adapter is enabled for the Microsoft Bluetooth stack in Microsoft Windows XP Service Pack 2 (SP2) or Windows XP Tablet PC Edition 2005.

Note The Windows XP SP2 features and components are included in Windows XP Tablet PC Edition 2005.

The Microsoft Bluetooth stack that is included in Windows XP SP2 does not let Bluetooth devices function until after you configure and pair the devices in Windows. This requirement helps prevent unauthorized access to your computer. When you connect the Bluetooth devices and then start the computer, the following behavior occurs:

1. When the computer starts, but before the Microsoft Bluetooth stack loads, the Bluetooth devices operate in Human Interface Device (HID) mode or by emulating a universal serial bus (USB) device.
2. When the Microsoft Bluetooth stack loads, it disables HID mode or USB emulation for the Bluetooth devices.

To resolve this issue, connect a wired keyboard and mouse to your computer to configure the Bluetooth devices.

The Bluetooth stack in Windows XP SP2 is designed to help prevent a Bluetooth device from connecting until you explicitly configure that device. This requirement helps prevent unauthorized access to your computer through a Bluetooth device.

Additionally, you must connect a wired keyboard and mouse to the computer to install Windows when Windows XP SP2 is integrated with the Windows XP installation media. (This installation is also known as a slipstream service pack installation.) When you install Windows XP by integrating the Windows XP SP2 service pack with the Windows XP installation media, Windows does not detect a Bluetooth mouse or a Bluetooth keyboard during the graphical user interface (GUI) mode part of the Setup program. Therefore, you cannot complete the Windows installation or log on to Windows by using a Bluetooth mouse or a Bluetooth keyboard.
