It has worked fine for several versions before. Error message from syslog is: Failed to set mode: Failed (0x03) Which according to various random forum posts seems to suggest the device is not powering on. Powering on manually also does not work: % bluetoothctl Agent registered [bluetooth]# power on Failed to set power on: org.bluez.Error.Failed And results in the same set mode failure getting logged again in syslog. hciconfig reports the device as down: % sudo hciconfig hci0: Type: Primary Bus: USB BD Address: 00:11:67:00:00:00 ACL MTU: 1021:4 SCO MTU: 48:10 DOWN RX bytes:498 acl:0 sco:0 events:21 errors:0 TX bytes:101 acl:0 sco:0 commands:24 errors:0 And, again, it refuses to power on: % sudo hciconfig hci0 up Can't init device hci0: Connection timed out (110) rfkill does not appear to be blocking it: % rfkill list 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no And systemd-rfkill.service is masked: ~ % sudo systemctl status systemd-rfkill.service ● systemd-rfkill.service Loaded: masked (Reason: Unit systemd-rfkill.service is masked.) [..] The system does not have tlp installed. I have tried numerous reboots, power offs, and moving the USB Bluetooth adapter to different ports, with no change in result. I have also tried unloading and loading btusb. The adapter is a cheap noname thing off of eBay, I trust the system report will provide every possibly interesting detail about it.
