Dan,

Your camera definitely uses the USB-Storage module for support.  I did a
search for the USB Device ID in your dmesg output there, and that device
is actually the example device used here:

http://www.linux.com/howtos/USB-Digital-Camera-HOWTO/c249.shtml

The "Is not claimed by any active driver" message means that the
appropriate driver isn't loaded.

USB Storage uses SCSI emulation, so make sure that you have the
following modules loaded:

scsi_mod	(The SCSI Subsystem)
sd_mod		(SCSI Disk Support)
usb-storage	(USB 
vfat		(fat filesystem)

If you still can't get it working, try upgrading the kernel.  Redhat has
provided several errata kernels since 2.4.18-3 was released, including
fixes for 2 local root exploits, so an update wouldn't be a bad idea
anyways.
