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.
