Bug Description
I have a bluetooth mouse (Genius Traveller 9005BT) that I have been using without problems with Ubuntu for over a year. Since a few weeks ago, however, it started disconnecting and reconnected from the computer. The symptoms are like this:
1. The mouse works, and the bluetooth icon on the computer is visible (in gnome-shell's top bar)
2. The mouse stops working, but the bluetooth icon is still visible. This state lasts between 1 and 10 seconds.
3. The bluetooth icon vanishes. This can last for half a second if I keep trying to use the mouse, to forever I I leave the mouse alone
4. The bluetooth icon reappears and the mouse starts working again. This state last from 2-3 seconds if I don't move the mouse, to seemingly forever if I continuously move the mouse
This seems to occur only after a suspend/resume cycle, and rebooting the computer fixes the issue.
The only thing I see in syslog is this when the mouse reconnects:

I just noticed that I can do this instead of rebooting to work around the issue:
sudo hciconfig hci0 down
sudo hciconfig hci0 up
