Is the device mounted? Typically, you plug in the USB Mass Storage
device, then do "mount /dev/sda1 /mnt/somewhere". I don't use Redhat,
and they may have automated this mounting process for digital cameras
(dumb idea) but you should check. After you plug the camera in, open an
xterm or konsole or Eterm, then enter "mount". You will see a list of
mounted devices, like so:

/dev/hda6 on / type ext3 (rw,noatime)
proc on /proc type proc (rw)
none on /proc/bus/usb type usbdevfs (rw)
//opus/dev on /mnt/opus type smbfs (0)
/dev/hde1 on /mnt/cf type vfat (rw,umask=000)

/dev/hda6 is my root filesystem, //opus/dev is a 'Doze2K machine with an
SMB share called DEV, and /dev/hde1 is a PCMCIA CompactFlash adapter.

The output from "mount" should include the string "/mnt/camera". If it
doesn't, do "mount /mnt/camera". You can set up a pointy-clicky
shortcut for this in KDE by right-clicking on the desktop, choosing
"Create New->Hard Disk", then choosing "/dev/sda1 (/mnt/camera)" in the
"Device" tab.

If /mnt/camera is indeed mounted, but nothing shows up when you do "ls
/mnt/camera", then it gets more complicated. Post the output of
"lsmod" and the output of "dmesg | tail -30".
