What device is it.
# lsusb

What options is it getting automounted with? What are you using to view its content (what application)? What user privileges and FC9 settings do you have?

lsusb output

lsusb output is as follows

[root@localhost ~]# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub


I think automounter is not installed on my system. option used to mount is not visible to me, issue 'mount' command doesn't show mounted usb. What i recognized now that usb get unmounted in few second even without browsing its content. mounting and unmounting happen in loop.


thanks

try to put the usb then restart your pc allow linux to detect during startup.

AUTOMATIC MOUNTING OF USB

1. goto /mnt
2. mkdir usb
3. you try to vi /etc/fstab
4. "mount /dev/sda1 /mnt/usb vfat,user,noauto 0 0"
5 after you edit press ESC :wq to save your new settings

try this if it is ok

hope it helps.
