usb digital camera detection problems on Fedora Core 2

I'm using Fedora Core 2, I just recently upgraded from FC1. I'm having difficulties with accessing my digital camera (Canon Digital Ixus 430). It worked with FC1.

I get the following stuff:
[root@localhost root]# dmesg|tail -15

I also can't mount any sda device when I try
mount -t vfat /dev/sda* /mnt/usbcam,
with * some numbers
(mount: /dev/sda is not a valid block device)

So apparently he sees some USB stuff, but not my camera.
Ideas anybody?

1) Try not specifying a filesystem type
2) Make sure you have the neede modules loaded

Here's what I use:

mount /dev/sda1 /mnt/camera -o uid=500,gid=500

the uid/gid stuff is just so the user can modify the contents of the card, instead of root having to do it.

The usb-storage module is needed; it seems to me that there was another one, too, but in more recent versions of Linux, identifying the needed modules for this particular operation hasn't been needed.

For more info, google or:
