• To check USB Port in Ubuntu 

            $ lsusb -t

• To install ubsview in Ubuntu 16.04

           $ sudo apt-get install usbview

• ls /dev > notplugged
• # plug in device
• ls /dev > plugged
• diff notplugged plugged

       if above does not work try this one

$ ls /dev 

then

$ dmesg | grep ttyS

You will get like this

put the command as in picture after that if you will get like this  it means your USB is connected at ttyS0

Now to check for any USB to serial converter use dmesg | grep tty command.


$ dpkg -l libusb-1.0*
