Title:
  USB to Serial Device not assigned to a  ttyUSB device

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I am running a current-updated version of 14.04.

  I have a USB to Serial cable with an embedded FTDI chip.

  When I plug the cable in, I *think* it should be assigned a
  /dev/ttyUSB0 slot...I can then map that as need for my application.

  I do not get this assignment.
