(CLI and GUI)
The problem is i cant see my files inside the USB upon insertion. I can only see me files after I clicked the icon in the Desktop.
-i used "ls -l" to view my files, but nothing was there.(without clicking the icon), but when i clicked the icon, and typed "ls-l" again, it was there.

Is there a way to detect the files inside a USB flash drive without clicking the icon in the Desktop?

i added this line in fstab:
/dev/sda2 /media/sda2 vfat auto,users,exec 0 0
***this allows me to mount a USB without typing "mount" command every boot up.
