I don't know either. I have the same behavior as Peng Deng and it stops working if I don't use it for a while.

I hope we're going to get a update to bluez that fixes this. -- [Jaunty] Cannot connect to a bluetooth mouse https://bugs.launchpad.net/bugs/343727 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
