to mount follow these basic steps
# tail -f /var/log/messages
you are looking for the USB to connect (so do this BEFORE you plug the usb device in)
it will be /dev/sdx#
still as root:
chmod -R 4777 /mnt/flashdrive
now edit the fstab:
/dev/<device from above> /mnt/flashdrive auto noauto,users,rw 0 0
now mount and test the fstab changes:
ls -laF /mnt/flashdrive
chmod -R 4777 /mnt/fashdrive
that last mount is done as user. thus the 4777 sticky bit completely UNSECURE permissions on the flash drive. 4777 says it will always be usable and accessible to ANYONE/USER on that computer.
you are done. umount and pull it out of the system.
