Thanks Jon, for the link. I tried modifying my current driver installation. 
It still shows the same error. 

Although, now the board boots up but the serial connection gets dropped. 
The serial and power connections are somehow still mutually exclusive. The 
serial connection appears only when I turn off and plug out the micro-USB 
(power).
