Title:
  USB 3.0 feature not working on Asus X553MA, Working in USB 2.0 mode
  only

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  The USB 3.0 port which comes with Asus X553MA seems not to be working on Xubuntu 14.04. I have tried several kernels including 4.0 rc 4 mainline kernel. Currently getting USB 2.0 speeds of maximum 30 MBps only. 
  This was earlier working previously with one of the kernels or OS, i donot remember exactly. May be the stock kernel that came with Xubuntu 14.10 or Linuxmint 5.
