+Subject: [PATCH 14/22] grub-core/bus/usb: Parse SuperSpeed companion
+ descriptors
+
+Parse the SS_ENDPOINT_COMPANION descriptor, which is only present on USB 3.0
+capable devices and xHCI controllers. Make the descendp an array of pointers
+to the endpoint descriptor as it's no longer an continous array.
+
