Affects Olimex CH340 USB-to-serial chips too.

Reverting to 3.13.0-63 restores normal function.

Title:
  3.13.0-65 upgrade vs. usb serial adapter

Status in linux-lts-trusty package in Ubuntu:
  Confirmed

Bug description:
    affects ubuntu

  Hi there,

  I'm using Kubuntu 14.04 32bit and 64bit on two different machines. Doing 
  embedded programming on a daily base, I'm using USB to serial adapters 
  based on the CP2102 IC. No problem so far. Today (September 29th) I 
  upgraded both computers from 3.13.0-63 to 3.13.0-65 as usual with this 
  command and passwd:

  sudo apt-get update && sudo apt-get upgrade -y && sudo apt-get 
  dist-upgrade -y

  After this and reboot, on both machines none of my several USB-serial 
  Adapters seem to work properly. I can receive with e.g. cutecom, but I 
  cannot send anymore. Any help will be apppreciated.

  Thanks Andreas
