  [Asus A8V-E DELUXE] ehci_hcd fatal error - USB devices randomly crash

Bug description:
  At seemingly random times (twice in the past week) all USB devices
  connected to the system suddenly stop working. /var/log/kern.log shows
  errors from ehci_hcd, then usually several filesystem I/O errors from
  the USB hard disk. After this USB devices may automatically reconnect
  as USB 1.1 or may not work until the machine is rebooted.

  In one case I came home to find my USB mouse powered off, and messages
  like "host controller halted, very bad" in kern.log. USB hard disk was
  also inaccessible (I/O errors) and appeared to have locked up
  (constant blinking LED). After rebooting and plugging in my phone to a
  powered hub there were messages complaining about "insufficient
  available bus power", which doesn't sound like it makes a lot of sense
  (shouldn't the powered hub and the phone's battery be enough?).

  While browsing the web today again the controller crashed producing
  the messages shown in dmesg; in this case the devices reconnected as
  USB 1.1 and the hard disk is still partially accessible (some files
  can be read, others give I/O errors). The mouse kept working during
  this time. After the crash I disconnected and reconnected a few USB
  devices to see if anything else would happen, but it looks like ehci
  has already been unloaded.

  (Errors about "unknown partition table" happen because the drive is
  encrypted with Truecrypt.)
