С перерывами не удается подключиться к гарнитуре Beats Bluetooth от CLI

У меня есть Bluetooth-гарнитура Beats Studio Wireless, которая с перерывами не может подключиться к Kubuntu 14.10. Это происходит:

$ lsusb | grep -i blue

Error: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

Если я постоянно нажимаю на значок системного трея Blueman «Недавние подключения -> Звуковой приемник на Beats Wireless», то в конечном итоге гарнитура будет подключаться.
