Yes, that's a possibility. However, when I connect or disconnect my
digital camera there's no message at all showing up in my
kernlog/syslog. My understanding is that udev gets a message from
kernel if the status of a device changes, and since there's no
message, my problem seems not to be at level of the udev interface
file.


Well, your thinking makes sense to me, I don't see how much can happen
until the kernel sees it there.

Does it look like the camera itself may have a hardware problem?

Well, that would be the next thing to check as you have already
suggested you will do on your wife's computer.

Well, I was finally able to access my wife's machine. I connected the
camera to a USB port and powered the camera on (did no use wall wart
power), and nothing happened in syslog. That makes it sound like the
camera itself has broken, unless for some reason I needed external power
rather than batteries..

As long as the batteries have sufficient charge, I doubt the camera knows
the difference.

I assume the camera still takes pictures and can display them ok on itself
or else we wouldn't be discussing this topic.

If you have a windows machine to try it on, do so and, if it works, make
sure it's unmounted properly before disconnecting it. I'm not sure what
the terminology is for unmounting in Windows but there will probably be
some icon in the tray for doing that, there always seems to some icon in
the tray for stuff.
