After the first setup, Bluetooth worked well until reboot. It is very strange because I didn't installed any updates or made any configuration.
First time I loaded Bluetooth:
sudo modprobe btusb
sudo systemctl start bluetooth.service
bluetoothctlAfter reboot there is no more Bluetooth device. btusb wasn't loaded, and bluetooth.service wasn't running. rfkill is empty:
