OK, I see what you're getting at... I have a couple of USB books here (and
an overload of information), but I've definitely seen a "select this
interface for use" message somewhere in one of those.  So, I would agree to
your assertion that I can have only one interface selected at a time.

Hmmm... I wonder what I should expect a Windows host to do when I plug in a
device that says it has two interfaces, one an HID and one an MSD?  I'll
find out soon enough by experimentation, but I suppose it's possible that it
could select interface 1 when it needed to access the disk and interface 2
when it needed to access the mouse... hmmm that doesn't feel right -- does
that mean I can't move my mouse/disk while I'm listing files?

Ahh... the adventure continues :)

I appreciate the dialog -- it helps me to sort through the gush of
information flowing at me right now.
