Периодически не удается подключиться к Bluetooth-гарнитуре Beats из CLI

У меня беспроводная Bluetooth-гарнитура Beats Studio, которая периодически не может подключиться к Kubuntu 14.10. Вот что 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 в системном трее Blueman «Недавние подключения -> Аудио приемник по беспроводной сети Beats», то в конце концов гарнитура подключится.
