How to make Serial to USB Converter (Cable) work in Ubuntu

1. Get hardware address to which Serial-USB converter is attached

$ dmesg | grep tty

dmesg (display message or driver message) command is useful to gather hardware information loaded into kernel at the booting time or when a plug and play device is connected. You will get result something like below. Note down the port value, in my case it is ttyUSB0

2. Provide permission to this port

$ sudo chmod 666 /dev/ttyUSB0

You need to provide permission everytime you connect your serial-usb converter.

3. Try with Putty now to connect to your Serial device, it should work!
