+Subject: [PATCH] fastboot: turn the USB hostcontroller initcalls into async initcalls
+
+the USB host controller init calls take a long time, mostly due to a
+"minimally 100 msec" delay *per port* during initialization.
+These are prime candidates for going in parallel to everything else.
+
+The USB device ordering is not affected by this due to the
+serialized-within-eachother property of async initcalls.
