Following-up on #16: Obviously, this is _not_ the solution for everyone,
but for my work computer, system stability is far more important that
USB3. I disabled xhci in UEFI (so ehci is used instead) and have not had
any more non-responsive USB ports in close to two weeks.

Title:
  USB stops working after a while (xhci_hcd 0000:00:14.0: Timeout while
  waiting for setup device command)

Bug description:
  On my laptop the kernel will sometimes drop the USB hub. After this,
  the laptop doesn't recognise any device plugged in to the USB ports -
  plugging and unplugging any device I've tried into any of the USB
  ports produces no response, not even dmesg entries.

  Strangely this also applies to bluetooth - it no longer works once USB
  has dropped (possibly the module is hung of the bus internally).

  Once this has happened only a reboot fixes it; I've not managed to
  find any combination of module unload/reload or suspend cycles to
  reinitialise things correctly.

  Relevant snippet of dmesg:
