Title: 0930:0214 [Toshiba TECRA R700 PT318C-00F001] Bluetooth disabled until reloading btusb module Status in “linux” package in Ubuntu: Confirmed Bug description: When I boot my machine, the bluetooth indicator isn't present. The bluetooth section of the system control panel shows that bluetooth is off, and "bluetooth is disabled". But flipping the switch to "on" doesn't actually turn on bluetooth -- the switch in the GUI gets flipped to on, but bluetooth never actually comes up. If I navigate away and re-open the bluetooth control panel, the switch will be back to "off". Bluetooth works fine in Windows. Still, `rfkill list bluetooth` lists two devices: rfkill list bluetooth 0: Toshiba Bluetooth: Bluetooth Soft blocked: no Hard blocked: no 1: hci0: Bluetooth Soft blocked: no Hard blocked: no And hciconfig lists a device, marked "DOWN": hciconfig hci0: Type: BR/EDR Bus: USB BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0 DOWN RX bytes:34 acl:0 sco:0 events:3 errors:0 TX bytes:12 acl:0 sco:0 commands:4 errors:0 I can ask hciconfig to bring it up: hciconfig up hci0 Warning: unknown command - "hci0" hci0: Type: BR/EDR Bus: USB BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0 DOWN RX bytes:34 acl:0 sco:0 events:3 errors:0 TX bytes:12 acl:0 sco:0 commands:4 errors:0 sudo hciconfig hci0 up [sudo] password for mike: [0] hciconfig hci0: Type: BR/EDR Bus: USB BD Address: E8:39:DF:37:2B:72 ACL MTU: 1021:8 SCO MTU: 64:1 UP RUNNING RX bytes:530 acl:0 sco:0 events:24 errors:0 TX bytes:335 acl:0 sco:0 commands:24 errors:0 But neither the bluetooth indicator nor the bluetooth control panel reflect that bluetooth is up. WORKAROUND: sudo rmmod btusb && sudo modprobe btusb && rfkill unblock bluetooth which causes the bluetooth indicator to be displayed, and the bluetooth control panel to function normally.
