Print more info for -v runs and temp hack for usb vs uhub

Despite best efforts to regularize, there's a few tables in the system

uhub (where usb devices attach). Add a temporary workaround for this
until these places have been eliminated (likely my fault).

Second, when running verbose, describe what we're doing when
searching. This output can be quite long, but says exactly what's
going on (this output is to stdout, so it's useless for scripting).
