This may be a separate issue from the btusb binding problem described
above.

Additional data that may be relevant:

Hardware: MT7925 (Lenovo laptop, Ubuntu-based system)

Observed behavior:
- Bluetooth controller is present (bluetoothctl list works)
- bluetoothctl show → Powered: no
- bluetoothctl power on → org.bluez.Error.Failed
- GUI toggle successfully enables Bluetooth

Key finding:
The device is soft-blocked at boot:

rfkill list
→ hci0: Bluetooth
   Soft blocked: yes

Manually unblocking resolves the issue immediately:
sudo rfkill unblock bluetooth

Permanent workaround:
A systemd service that runs "rfkill unblock bluetooth" at boot resolves the 
issue completely.

Conclusion:
This appears to be a power/control state issue (rfkill), not a driver binding 
or firmware problem. Possibly related to ideapad_laptop or ACPI behavior.

It may be useful to investigate why Bluetooth is soft-blocked at boot on
this hardware.
