No one responded on this query, but, for the sake of posterity, here's
the fix:
Many modern digital cameras have two modes in which the flash memory
operates, USB and PTP; I do not know what PTP means, but the effect of
it is, it doesn't allow the memory to be seen as ordinary flash memory.
Digikam can recognize a connected device operating in PTP mode and
that's why it worked there. In Windows-land, PTP mode, as I understand
it, is designed to work with Nikon's own software for managing photos. I
do not know if other manufacturers use this protocol, or whether it's
unique to Nikon. On some Nikon cameras, there are options in the menu to
run the memory in USB or PTP mode, but, the D90 does not offer this
choice, and can only run in PTP. The fix is to either use Digikam or
other software that can work with PTP mode enabled memory, or, remove
the memory from the camera and use a card reader.

I'm having problem with one device, a Nikon D90 camera, that

automount. At some point in the past, I had set something that would
cause it to be detected, but the only option offered was to download
pictures with Digikam. (At some time in the past, the device notifier
would offer options including opening the device in Dolphin which is
what I'd prefer.) For some reason, this function didn't work properly
because Digikam would open and stall on the process of detecting my
images, and never would open. I have a very large image archive and this
process could take a couple of minutes in the past, but it would
eventually open. This camera will mount under Windows; however, in
Windows, the icon never appears that allows you to eject it gracefully
once you're ready to dismount it. When I attach the camera to the
Windows box, it automatically opens an explorer window and shows me the
folder structure, but, the eject button never appears.
