And then an icon of a USB stick appears on the desktop with Open, 
Unmount, Eject, etc (so it has obviously bee mounted, and indeed it 
shows in /media as USB DISK

With the help of the good folks on the enlightenment list, I fixed the 
original USB problem:

But I see nowhere in the interface where it says "do something different 
when the device identifies itself as a camera". In any case, this may be 
something that is handled correctly when using xfce: I haven't tested 
that yet, but I do remember from years past that getting a camera NOT to 
be usurped by an over-eager operating system that thinks it knows best 
was HARD.
