+# and then invoke btattach with the right parameters, this is intended to be
+# invoked from a hardware-activated systemd service

+# For now this only suports ACPI enumerated Broadcom BT HCIs.
+# This has been tested on Bay and Cherry Trail devices with both ACPI and
+# PCI enumerated UARTs.

+# Note the kernel bt developers are working on solving this entirely in the
+# kernel, so it is not worth the trouble to write something better then this.
