  Log:
  Use a different task queue for host controller and peripheral driver
  tasks. Since the host controllers rely on tasks to process transfer
  timeouts, if a synchronous transfer from a driver was invoked from
  a task and timed out, it would never complete because the single
  task thread was stuck performing the synchronous transfer so couldn't
  process the timeout.
  
  This affected the axe, udav and ural drivers.
