+Subject: [PATCH] ADB on linux: Handle USB SuperSpeed extra Descriptors
+
+Under Linux, ADB manually parses USB Descriptors to check for
+possible ADB USB Interfaces. USB Devices connected with SuperSpeed
+will exhibit extra USB SuperSpeed Endpoint Companion Descriptors.
+This patch handles these USB SuperSpeed specific USB Descriptors.
