+# Author: https://github.com/thekk1
+# Version: 1.5

+# https://github.com/ublue-os/bazzite/issues/1289
+# https://github.com/ValveSoftware/steam-for-linux/issues/8678
+#
+# Description:
+# This script monitors connected PS4 and PS5 gamepad devices and disconnects
+# the Bluetooth connection if specific button combinations are detected (Home and Triangle buttons).
+# The script handles background processes for each device and maintains a record of process IDs
+# to ensure proper cleanup of processes associated with devices that are no longer present.
+#
+# This script should be removed if there is a native solution under one of the mentioned issues.
+#
+# Usage:
+# ./bazzite-bluetooth-ds4-ds5-workaround [-d]
+# -d: Enable debug mode
