From 1109ef2dc48779edb875a009b75784228acfb316 Mon Sep 17 00:00:00 2001

Subject: Make uhub_explore() return an int rather than a usbd_satus.  This has
 no direct impact since its return value is never checked but it allows me to
 get rid of one (usless) status value.

Note that usbd_status should be used for USB transfers.
