+Subject: [PATCH 17/22] grub-core/bus/usb: Add function pointer for
+ attach/detach events
+
+The xHCI code needs to be called for attaching or detaching a device.
+Introduce two functions pointers and call it from the USB hub code.
+
+Will be used in future commits, currently this doesn't change any functionality.
