+Subject: [PATCH] HID accepts bonded device connections only.
+
+This change adds a configuration for platforms to choose a more secure
+posture for the HID profile.  While some older mice are known to not
+support pairing or encryption, some platform may choose a more secure
+posture by requiring the device to be bonded  and require the
+connection to be encrypted when bonding is required.
