[OT?] looking for intro-level content on USB

[Robert P. J. Day]

  i might have posted on this before once upon a time, but i'm looking
to collect some newbie-level linux-related USB explanatory content for
a seminar i'm supposed to give in a couple of weeks.

  in a nutshell (and is there any other kind?), it would be nice to
start from scratch and build up to the point where attendees could
then look at, say, the output from "lsusb" or the contents of
/proc/bus/usb/devices and understand what it all means.

  this wouldn't involve any USB kernel programming -- just the ability
to understand the basic USB technology, hierarchy and so on.  and,
yes, i'm aware of sites like linux-usb.org, but even those sites are
sadly sagging under the weight of out-of-date content.  so, rather
than pointers to sites in general, if you have a URL for a specific
page or tutorial, that would be even duckier.

  once i collate all of it, i'd be happy to summarize and put it up at
my wiki.  thanks.
