I've tried the latest suggestions and the dmesg results appear below the
second double dotted line below.
I am running Mandrake 8.1 -- kernel 2.4.8-26mdk
uname shows this:
Linux localhost.localdomain 2.4.8-26mdk #1 Tue Mar 5 11:59 EST 2002 i686
unknown
cat /proc/bus/usb/devices does recognize the camera connected by USB
cable by name, model number, and serial number ... so why can't I mount it?
The serial number shown, though, is different than the one imprinted on the
camera case. Does that matter?

As you suggested, I did this:
'rmmod usb-storage' followed by 'modprobe usb-storage',
then 'dmesg | tail -50'
The complete result of the last 'dmesg' is shown below the second
double dotted line (far below).
I also did a diff of dmesg results after 'rmmod usb-storage' (dmesg5)
and then after 'modprobe usb-storage' (dmesg6) which shows the
following info:
# /sbin/rmmod usb-storage
# dmesg _ tail -50 >> dmesg5
# modprobe usb-storage
# dmesg | tail -50 >> dmesg6
# diff dmesg5 dmesg6

The great mystery remains, why can't I mount the camera
and why does the attempted mount return "unknown device"
when 'cat /proc/bus/usb/devices' shows that the device is,
in fact, recognized and 'modprobe' establishes that the USB
Mass Storage device >IS< "found" and it has "support registered"?
# mount -t vfat /dev/sdb1 /mnt/camera
mount: /dev/sdb1: unknown device
