title: FTDI chip detection issue
body: <p>I'm trying to do some transactions over serial ftdi interface to an ARM based board. On windows i'm able to detect it but when from virtualbox i'm unable to detect the same.
  When i connect the same board to a linux sever box, it gets detected and gives me the port /dev/ttyuSB0. Any idea why Virtualbox does not detect?</p>
