Loading usbserial mobile on Ubuntu 14.04 LTS

I want to use USB to Serial Converter for serial connectivity.
I have one cable that provides the converter, but it does not have drivers for Ubuntu 14.04 LTS.
So I have downloaded FTDI drivers and copied the lib files as per the instructions.
I have also did “sudo modprobe usbserial vendor=0xXXXXX product=0xXXXXX” and then added it in the “/etc/modules”. For the first time use it did work from my java application but then after it started giving serial read timeout error, and some how I am stuck with this error now.

So I have below questions:

  1. Do I need to install any drivers for USB to Serial Converter?
  2. Also do I need to do “sudo modprobe usbserial…” is it required?
  3. What is the cause of read timeout?
