You may occasionally experience the following symptoms when you wake a Windows Vista-based computer from sleep:

•	A Bluetooth device no longer works correctly.
•	When you view the Bluetooth device in Device Manager, an exclamation mark in a yellow circle is displayed for the device. When you view the properties of the device, the status for the device reports Code 43. This status code indicates that Windows has stopped the device because the device has reported problems.

This problem occurs on a system in which a Bluetooth device is connected through a universal serial bus (USB) connection.

Note The Bluetooth device may be an external USB Bluetooth transceiver, or it may be integrated into the system by using an internal USB hub. For example, a portable computer may use an internal USB hub to provide external USB ports and to connect to integrated USB-based devices.
