If the USB is formatted with FAT32 you have to set the perms when mounting ("mount -t vfat -o uid=lina,gid=lina,utf8,umask=xxx...") which is done automatically when your DE mounts it. Remmeber that FAT32 filesystem is completely unaware about file/folder ownership and permissions. Greetings, -- Camaleón
