The error occurs because your Bluetooth adapter's USB ID is not
recognized by the btusb driver.
Quick Fixes:
Check Device ID: Run lsusb to find your adapter's vendor and product ID.
Update Driver: Update your OS or manually add the USB ID to the btusb.c file and rebuild the driver.
Install Firmware: Ensure required firmware files are in /lib/firmware/.
Inspect Logs: Use dmesg | grep bluetooth to gather more details.
Seek Support: Contact the manufacturer or refer to forums for specific patches.

Bug description:
[Impact]
BT hardware is not available on certain machines:
1. Machine with MT7925 BT (USB VID/PID 13d3/3628)
2. Machine with MT7925 BT (USB VID/PID 0489/e14e)
[Fix]
Add USB device IDs into device table in btusb.c fixes the issue.
1. For VID/PID 13d3/3628, the patch has already been merged into
linux-next:
f597b8982d51 Bluetooth: btusb: Add new VID/PID 13d3/3628 for MT7925
2. For VID/PID 0489/e14e, the patch is still under review. Out of the
urgency, we're going to make a SAUCE patch first.
[Test Plan]
1. Install Ubuntu image and boot into the OS
2. Run $ sudo checkbox-cli run com.canonical.certification::bluetooth/detect-output and see if the test is passed
[Where problems could occur]
The two BT hardware may have not yet been matured, so there might be issues in the future.
