I disabled the bluetooth adapter by mistake, and after a restart I can no longer enable it.
rfkill list all
0: tpacpi_bluetooth_sw: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
and after enabling modprobe btusb and restarting the bluetooth systemd service, I get
