Try putting this line in /etc/fstab:
/dev/sda /mnt/usb vfat defaults 0 0
If you want to make it more readable, put tabs between each param
instead of spaces.
Firstly, make sure that usb-storage is in the output of 'lsmod':
[root@xxxxxxx root]# lsmod
Module Size Used by
usb-storage 39008 0 (unused)
usb-uhci 21536 0 (unused)
usbcore 51712 0 [usb-storage usb-uhci]
You should see something like the above. If not, try 'modprobe
usb-storage' and it should add it. If it isn't there, you may wish to
put 'modprobe usb-storage' at the end of you /etc/rc.d/rc.local file so
it runs every time the machine is booted.
Secondly, plug your disk in and power up - make sure there is mention of
it in the output of the 'dmesg' command:

(yes I know it's actually a digital camera and not a disk, but they use
the same interface dammit).
The important line here is the one that says sda: sda1, although you
will probably see the same if you have no other scsi devices on your
system.
I then did mount /mnt/sda1 /mnt/usb, and it worked just fine. This was
without anything in the fstab. Conversely, if you *did* put entries in
the fstab, you would only need to do something like 'mount /mnt/usb'.
That's half the point of the fstab file.
If that doesn't work, then try mount /mnt/sda /mnt/usb Another good
thing to note is that you shouldn't need to specify a file type 90% of
the time. Linux is generally smart enough to work it out on it's own.
