Estou usando o Debian Jessie (teste). Eu tenho um mouse bluetooth (Microsoft Sculpt Comfort) e posso emparelhá-lo e usá-lo ok, mas depois de algum tempo de inatividade (em torno de 10 minutos) ele para de funcionar, tenho que tocar manualmente no set discoverable botão no mouse e re-emparelhá-lo na linha de comando.
O mesmo mouse que eu tentei no OS X e funciona, então não é um problema de hardware
Kernel 3.14.12-1 (2014-07-11)
Eu emparelhei o mouse com este comando:
sudo hidd --connect 30:59:B7:72:A5:A7
Quando emparelhado corretamente, esta é a saída / var / log / syslog
Jan 7 15:22:42 desktop hidd: New HID device 30:59:B7:72:A5:A7 (Microsoft Bluetooth Mouse )

Após algum tempo ocioso, isso é impresso no mesmo arquivo de log:
Jan 7 15:34:34 desktop acpid: input device has been disconnected, fd 20
Se eu clicar com o botão do mouse ou movê-lo, isso será impresso:
Jan 7 15:49:55 desktop bluetoothd[650]: Refusing input device connect: No such file or directory (2)
Jan 7 15:49:56 desktop bluetoothd[650]: Refusing connection from 30:59:B7:72:A5:A7: unknown device
O que parece indicar que o mouse ainda está funcionando e tentando fazer com que o sistema operacional se reconecte, mas não pode.
Esta é a resposta do udevadm info -p :
