bluetooth problems

Рабочая ОС - Fedora, постоянно отваливается bluetooth и, соответственно, bluetooth-мышка.

Набрав dmesg, видим следующую ошибку:
[162742.155590] Bluetooth: hci0: last event is not cmd complete (0x0f)
[162758.026567] Bluetooth: hci0: last event is not cmd complete (0x0f)
[162773.898560] Bluetooth: hci0: last event is not cmd complete (0x0f)
[162790.282573] Bluetooth: hci0: last event is not cmd complete (0x0f)
[162806.154573] Bluetooth: hci0: last event is not cmd complete (0x0f)
[162822.025571] Bluetooth: hci0: last event is not cmd complete (0x0f)

Далее, грепаем по firmware:
$ dmesg | grep -i firmware

Видим:
[52159.395988] bluetooth hci0: Direct firmware load for rtl_bt/rtl8723b_config.bin failed with error -2
[75519.659634] bluetooth hci0: Direct firmware load for rtl_bt/rtl8723b_config.bin failed with error -2

[95998.271165] bluetooth hci0: Direct firmware load for rtl_bt/rtl8723b_config.bin failed with error -2

Временно устраняем проблему:
$ modprobe -r btusb
$ modprobe btusb
