Title:
  [Dell Inspiron 3137] Atheros Bluetooth [0cf3:0036] does not work on
  this system

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  CID: 201307-13940 Dell Inspiron 3137

  The Bluetooth controller, Atheros AR3011 [0cf3:0036], is not working on this system.
  (According to bug 1288180 and bug 1219660, this device should work in 12.04.4)

  Steps:
  1. Install 12.04.4 + update (3.11.0-20), boot to desktop
  2. Try to pair with any device

  Expected result:
  * Bluetooth applet available and working normally.

  Actual result:
  * The Bluetooth applet is not there, just like there is no such device on this system.
  * You could see this device in lsusb, but few minutes later, it will disappear.

  Cause:
  ath3k's firmware loading function works badly with xHCI.
