how to mount usb flash memory on RHEL 3.0


How can I mount USB flash memory on RHEL 3.0 ?
I added the following line to fstab & used following mount command:
/dev/sdc1 /mnt/usb vfat user,noauto 0 0 <-- added to /etc/fstab
mount /mnt/usb <-- mount command
/dev/sdc1 is not a valid block device <-- got this errmsg

I read in another post from Villajohn Nov 29/04 that usb flash
memory is configured as a scsi disc
Since I have 2 SCSI discs, sda & sdb, I guessed that
the USB flash memory would be sdc ?? but errmsg says otherwise
How can I tell which scsi device to use ?

After I installed my USB card (adaptec USB2connect)
I did see bootup messages such as:
usb.c: registered new driver usbdevfs
PCI found IRQ for device 00:1f.2
PCI sharing IRQ 9 with 01:0b.0
usb-uhci.c: detected 2 ports
usb-uhci.c: v1.275.USB universal host controller interface driver
usb.c registered new driver hiddev

How can I tell which SCSI device to use ?
Thanks, Owen

jhibbets:
Thanks for solving my problem.
I had looked in dmesg for the scsi device assigned but I needed
to reboot a 2nd time before it showed up, And it was sdc1 as
we would expect since I have 2 SCSI hard disks.
There is 1 minor problem, the permissions are reset to 755
when I mount (I set 777 before mounting on /mnt & /mnt/usb)
I tried modifying /etc/security/console.perms similar to my
other posting reply which worked for the floppy drive
I modified the <flash>=/mnt/flash* to <flash>=/mnt/usb
& chnaged <console> 600 <flash> 0600 root
to ---------> <console> 666 <flash> 0666 root
But I can live with using root to write to my usb flash memory
if no easy solution to the permissions problem
Thansk again, Owen
