I have a problem when trying to work with USB devices mounted with user 'root'. I explain, I mount a USB device as root under command line (console mode only), and I can work with that device with no problem, but when changing to one limited account, that device mounted is in read-only mode. I've tried to apply chmod and chown but not to work. Also, I've tried this:

$ sudo mount -t vfat -o rw,users /dev/sdb1 /mnt/pen/

and same result. How can I resolve this without using fstab file? I think there must be a solution, 'cause under X-Windows with a limited account, this USB device is recognized, mounted and worked with no problem.

Try using the uid and gid bits to specify you as the userID which owns the file. You may also want to use umask:

sudo mount -t vfat /dev/sdb1 /mnt/pen -o umask=022,rw,uid=1000,gid=1000

Under GNOME, there's an automounter (part of Gnome-VFS) that provides automounting when HAL/Dbus notifies it that a new device has become available (USB stick plugged in, CD inserted, etc).

To run a 1-off on the commandline, use the mount options uid and/or gid (and/or umask) as John T's answer shows.

To run a system-wide automounter, use HALevt. See my answer to this question for getting HALevt to work on a headless system. In your case, you might tweak things to run the HALevt daemon as your user.
