By the way, setting that USB wakeup setting in the BIOS seems to have
some effect for me.  The port no longer dies after suspend but instead
it just doesn't work very well (random disconnections, file transfers
from my digital camera fail).

Title:
  [Samsung NP900X4C-A03US] USB 3.0 ports don't work after suspend,
  xhci_hcd errors in kernel log

Status in “linux” package in Ubuntu:
  Incomplete
Status in Arch Linux:
  New

Bug description:
  My laptop has one USB 2.0 port and a couple of USB 3.0 ports.  The USB
  3.0 ports only work after a fresh shutdown/restart, not after I
  suspend/resume.  There are a couple of different USB controllers
  listed in lspci:

  $ sudo lspci -nn | grep USB
  00:1d.0 USB controller [0c03]: Intel Corporation 7 Series/C210 Series Chipset Family USB Enhanced Host Controller #1 [8086:1e26] (rev 04)
  03:00.0 USB controller [0c03]: Renesas Technology Corp. Device [1912:0015] (rev 02)

  lsusb lists a 3.0 root hub along wit the 2.0 one.

  $ sudo lsusb
  Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
  Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
  Bus 001 Device 003: ID 8087:07da Intel Corp.
  Bus 001 Device 004: ID 2232:1024

  I see the following errors in dmesg output (and nothing when I
  plug/unplug a device):

  $ dmesg | grep xhci
  [ 3916.808221] xhci_hcd 0000:03:00.0: WARN: xHC restore state timeout
