I'm poking around here and getting a certain degree of progress 
but no joy.  

"fdisk /dev/sd/c0b0t0u0" returns "Unable to read /dev/sd/c0b0t0u0" and
in /var/log/messages the following appears:

Dec 29 13:25:07 juanita kernel: usb-uhci.c: interrupt, status 3, frame#
374

REQUEST.

sectors (8 MB)

Dec 29 13:25:07 juanita kernel:  unable to read partition table
Dec 29 13:25:07 juanita kernel:  I/O error: dev 08:00, sector 0

By the way, "cat /proc/bus/usb/devices" returns:

Unfortunately, the KDE Control Center and the add camera dialog for
gtkam does not have my camera (Vivitar Vivicam 3555t) listed, and I
don't have any equivalency info for this cam and Google turns up nothing
so far.

So:  SmartMedia card reader for me?  And, what of that 6-in-1 card
reader thing I saw?  I don't even understand how such a bugger is
supposed to hook up inside the box.
