Pairing a DualShock 3 over Bluetooth on modern Linux (BlueZ 5.85) when the sixaxis plugin is broken

On some modern distros (tested: Ubuntu-based, BlueZ 5.85, kernel 7.x) the built-in BlueZ sixaxis plugin silently does nothing — plug the controller in over USB and it never sets the master address, never registers the device, never writes an SDP record. The result is either no connection at all, or a controller that connects and instantly disconnects (js0 flaps), with this in journalctl -u bluetooth:

profiles/input/device.c:hidp_add_connection() Could not parse HID SDP record: No such file or directory (2)

Configuration Security

Detect secrets in code

Identify missing authentication checks
Detect improper authorization patterns

	#!/usr/bin/env bash
	# ds3-bluez-setup.sh — pair a DualShock 3 / Sixaxis over Bluetooth using pure BlueZ
	# (no sixad). Run with the controller connected via USB cable. Needs sudo.
	#
	# sudo ./ds3-bluez-setup.sh
	#
	# What it does (the 5 steps):
	# 1. Writes this host's adapter MAC into the controller (hidraw report 0xf5)
	# 2. Trusted-but-not-bonded device entry under /var/lib/bluetooth
	# 3. Pre-seeds a correct DS3 HID SDP record in BlueZ's cache (the key fix)
