Subject: [Bluez-users] Bluetooth Mouse and kbd looses connection after some time of inactivity

I have a logitech dinovo bluetooth mouse and keyboard on a Ubuntu 64bit box.

I can pair both easily using the tray applet, and they both work
flawlessly initially.
However, after some time of inactivity (Not using one mouse for some
time, Going away from the System, etc) the connection is lost and
won't be re-established, even after moving the mouse constantly.
In bluetooth manager i can see the both devices are still listed like
connected.

To make them work again i have to manual disconnect them. After that i
can move the mouse and click the kbd and they reconnect immediatly.

Kernel version is 2.6.24.16 (also have this problem in 2.6.22).
