+### Misbehaving Bluetooth devices
+
+Bluetooth or bluetooth devices turning themselves off after a few hours and
+recovering a system reboot to work again? Enter Bluetooth autosuspend on
+Linux. Alternatively it could be a case of device requiring a HID reset
+command on reboot. There are two solutions:
+
+- Configure the Bluetooth kernel module through kernel command line parameters
+  `btusb.enable_autosuspend=0 btusb.reset=1`
+- Or configure `/etc/modprobe.d/<whatever-you-want>.conf` with
+  `options btusb enable_autosuspend=0 reset=1`
