There's a regression somewhere between bluez 5.69 bluez-libs 5.69 (working) and latest (currently 5.73) that breaks Bluetooth for device :
bluetooth.service says condition unmet : /sys/class/bluetooth/ not found, checking it;
looking through the log there's also errors :
attachment is logs taken from the working version.
Bus 001 Device 010: ID 0bda:b00a Realtek Semiconductor Corp. Realtek Bluetooth 4.2 Adapterbluetooth.service says condition unmet : /sys/class/bluetooth/ not found, checking it;
/sys/class/bluetooth/ exists but is empty when it's supposed to have a symlink from /sys/class/bluetooth/hci0/ to /sys/devices/pci0000:00/0000:00:08.1/0000:03:00.3/usb1/1-4/1-4:1.0/bluetooth/hci0/looking through the log there's also errors :
