Provide access to USB devices

I have been having problem with accessing USB devices I use in the lab. Whenever I unplug device and plug it again, it always cries for providing admin access. So here is what I did :

jenis@Jenis-Laptop:~$ ls -al /dev/ttyUSB0

crw-rw---- 1 root dialout 188, 0 Sep 19 12:15 /dev/ttyUSB0

Add your user to dialout group by using :

"sudo adduser jenis dialout"

And you are done. Restart/Re-log your machine.
