Unable to automount USB.

I am trying to enable auto mount usb in Unity. I followed this post.

Mean while I faced the error:

sudo mount -t vfat /dev/sdb1 /media/usbstick
mount: special device /dev/sdb1 does not exist error

Before and after connecting USB.

ravan@ravan:~$ ls /dev/ | grep sd

ravan@ravan:~$ ls /dev/ | grep sd

I have tried posts linked here

EDIT 1:

I solved the error by creating partition using gparted. Still auto mount problem exists.

ravan@ravan:~$ lsblk

your USB have only raw disk space. there is no partition. see your output TYPE of sdb:

ravan@ravan:~$ lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 931.5G  0 disk 
├─sda1   8:1    0 120.1G  0 part 
├─sda2   8:2    0     1K  0 part 
├─sda3   8:3    0 255.4G  0 part 
├─sda5   8:5    0  16.3G  0 part [SWAP]
├─sda6   8:6    0  39.6G  0 part /
├─sda7   8:7    0  99.4G  0 part /home
└─sda8   8:8    0 400.7G  0 part 
sdb      8:16   1   3.8G  0 disk 
sr0     11:0    1  1024M  0 rom 

First you have to create partition and assign complete space to that partition. then you will be able to do that.

For that you have to go:

sudo fdisk /dev/sdb

press n to create partition and follow other option and assign complete space to this single partition.you can take help from here to create partition.

NOTE: disk never mount
